--- HTTP/3 is coming! And it won't use TCP! ---

A recent announcement reveals that HTTP - the protocol used by browsers to communicate with web servers - will get a major change in version 3!

Before, the HTTP protocols (version 1.0, 1.1 and 2.2) were all layered on top of TCP (Transmission Control Protocol).
TCP provides reliable, ordered, and error-checked delivery of data over an IP network.
It can handle hardware failures, timeouts, etc. and makes sure the data is received in the order it was transmitted in.
Also you can easily detect if any corruption during transmission has occurred.
All these features are necessary for a protocol such as HTTP, but TCP wasn't originally designed for HTTP!
It's a "one-size-fits-all" solution, suitable for *any* application that needs this kind of reliability.
TCP does a lot of round trips between the client and the server to make sure everybody receives their data. Especially if you're using SSL. This results in a high network latency.
So if we had a protocol which is basically designed for HTTP, it could help a lot at fixing all these problems.
This is the idea behind "QUIC", an experimental network protocol, originally created by Google, using UDP.

Now we all know how unreliable UDP is: You don't know if the data you sent was received nor does the receiver know if there is anything missing. Also, data is unordered, so if anything takes longer to send, it will most likely mix up with the other pieces of data. The only good part of UDP is its simplicity.
So why use this crappy thing for such an important protocol as HTTP?
Well, QUIC fixes all these problems UDP has, and provides the reliability of TCP but without introducing lots of round trips and a high latency! (How cool is that?)

The Internet Engineering Task Force (IETF) has been working (or is still working) on a standardized version of QUIC, although it's very different from Google's original proposal.
The IETF also wants to create a version of HTTP that uses QUIC, previously referred to as HTTP-over-QUIC. HTTP-over-QUIC isn't, however, HTTP/2 over QUIC.
It's a new, updated version of HTTP built for QUIC.

Now, the chairman of both the HTTP working group and the QUIC working group for IETF, Mark Nottingham, wanted to rename HTTP-over-QUIC to HTTP/3, and it seems like his proposal got accepted!
So version 3 of HTTP will have QUIC as an essential, integral feature, and we can expect that it no longer uses TCP as its network protocol.

We will see how it turns out in the end, but I'm sure we will have to wait a couple more years for HTTP/3, when it has been thoroughly tested and integrated.

Thank you for reading!

My first job: The Mystery of The Powered-Down Server

I paid my way through college by working every-other-semester in the Cooperative-Education Program my school provided. My first job was with a small company (now defunct) which made some of the very first optical-storage robotic storage systems. I honestly forgot what I was "officially" hired for at first, but I quickly moved up into the kernel device-driver team and was quite happy there.

It was primarily a Solaris shop, with a smattering of IBM AIX RS/6000. It was one of these ill-fated RS/6000 machines which (by no fault of its own) plays a major role in this story.

One day, I came to work to find my team-leader in quite a tizzy -- cursing and ranting about our VAR selling us bad equipment; about how IBM just doesn't make good hardware like they did in the good old days; about how back when _he_ was in charge of buying equipment this wouldn't happen, and on and on and on.

Our primary AIX dev server was powered off when he arrived. He booted it up, checked logs and was running self-diagnostics, but absolutely nothing so far indicated why the machine had shut down. We blew a couple of hours trying to figure out what happened, to no avail. Eventually, with other deadlines looming, we just chalked it up be something we'll look into more later.

Several days went by, with the usual day-to-day comings and goings; no surprises.

Then, next week, it happened again.

My team-leader was LIVID. The same server was hard-down again when he came in; no explanation. He opened a ticket with IBM and put in a call to our VAR rep, demanding answers -- how could they sell us bad equipment -- why isn't there any indication of what's failing -- someone must come out here and fix this NOW, and on and on and on.

(As a quick aside, in case it's not clearly coming through between-the-lines, our team leader was always a little bit "over to top" for me. He was the kind of person who "got things done," and as long as you stayed on his good side, you could just watch the fireworks most days - but it became pretty exhausting sometimes).

Back our story -
An IBM CE comes out and does a full on-site hardware diagnostic -- tears the whole server down, runs through everything one part a time. Absolutely. Nothing. Wrong.

I recall, at some point of all this, making the comment "It's almost like someone just pulls the plug on it -- like the power just, poof, goes away."

My team-leader demands the CE replace the power supply, even though it appeared to be operating normally. He does, at our cost, of course.

Another weeks goes by and all is forgotten in the swamp of work we have to do.

Until one day, the next week... Yes, you guessed it... It happens again. The server is down. Heads are exploding (will at least one head we all know by now). With all the screaming going on, the entire office staff should have comped some Advil.

My team-leader demands the facilities team do a full diagnostic on the UPS system and assure we aren't getting drop-outs on the power system. They do the diagnostic. They also review the logs for the power/load distribution to the entire lab and office spaces. Nothing is amiss.

This would also be a good time draw the picture of where this server is -- this particular server is not in the actual server room, it's out in the office area. That's on purpose, since it is connected to a demo robotics cabinet we use for testing and POC work. And customer demos. This will date me, but these were the days when robotic storage was new and VERY exciting to watch...

So, this is basically a couple of big boxes out on the office floor, with power cables running into a special power-drop near the middle of the room. That information might seem superfluous now, but will come into play shortly in our story.

So, we still have no answer to what's causing the server problems, but we all have work to do, so we keep plugging away, hoping for the best.

The team leader is insisting the VAR swap in a new server.

One night, we (the device-driver team) are working late, burning the midnight oil, right there in the office, and we bear witness to something I will never forget.

The cleaning staff came in.

Anxious for a brief distraction from our marathon of debugging, we stopped to watch them set up and start cleaning the office for a bit.

Then, friends, I Am Not Making This Up(tm)... I watched one of the cleaning staff walk right over to that beautiful RS/6000 dev server, dwarfed in shadow beside that huge robotic disc enclosure... and yank the server power cable right out of the dedicated power drop. And plug in their vacuum cleaner. And vacuum the floor.

We each looked at one-another, slowly, in bewilderment... and then went home, after a brief discussion on the way out the door.

You see, our team-leader wasn't with us that night; so before we left, we all agreed to come in late the next day. Very late indeed.

Also a big “fuck you” to whoever decided under any circumstance holding the power button down on a computer case meant anything other than shut this mother fucker all the way down and try the fuck again.

Gahhh. When I hold the power button I don’t what you to sleep, I want you to die! I’m electronically smothering your bitch ass. When I’m holding down the power button to restart, the computer should feel like it’s being waterboarded! Like these may be it’s last moments on Earth if it doesn’t act right and get in compliance! No it’s not nap time, it’s time to shut up or shut down...forever!

Oh the joy of helping elders with their computers..

...

Client: My computer is broken.

*Me expecting some kind of hardware issue*

Me: In what way is it broken? Are you able to start the computer?

Client: Yes. I can read Windows and then there's a login. It works fine but then It's broken.

*me standing next to client while client struggles to type password*

...

*5 minutes and a coffee brake later*

/* the client is finally able to figure out the password.. What a suprise! A note in the drawers containing all passwords.. */

Me: I'm sorry but I can't see any problems so far. You are supposed to be welcomed by your desktop *points at screen*. In what way is it broken?

Client: It's not the same as before. *now the client points at the screen*. Here. There used to be a picture here. It took me to <site>. Now It's not there. Something has changed.

*realizing that the client has lost his shortcut and wants a new one*

Oh the joy of helping elders with their computers.

Well, here's the OS rant I promised. Also apologies for no blog posts the past few weeks, working on one but I want to have all the information correct and time isn't my best friend right now :/

Anyways, let's talk about operating systems. They serve a purpose which is the goal which the user has.
So, as everyone says (or, loads of people), every system is good for a purpose and you can't call the mainstream systems shit because they all have their use.

Last part is true (that they all have their use) but defining a good system is up to an individual. So, a system which I'd be able to call good, had at least the following 'features':
- it gives the user freedom. If someone just wants to use it for emailing and webbrowsing, fair enough. If someone wants to produce music on it, fair enough. If someone wants to rebuild the entire system to suit their needs, fair enough. If someone wants to check the source code to see what's actually running on their hardware, fair enough. It should be up to the user to decide what they want to/can do and not up to the maker of that system.
- it tries it's best to keep the security/privacy of its users protected. Meaning, by default, no calling home, no integrating users within mass surveillance programs and no unnecessary data collection.
- Open. Especially in an age of mass surveillance, it's very important that one has the option to check the underlying code for vulnerabilities/backdoors. Can everyone do that, nope. But that doesn't mean that the option shouldn't be there because it's also about transparency so you don't HAVE to trust a software vendor on their blue eyes.
- stability. A system should be stable enough for home users to use. For people who like to tweak around? Also, but tweaking *can* lead to instability and crashes, that's not the systems' responsibility.

Especially the security and privacy AND open parts are why I wouldn't ever voluntarily (if my job would depend on it, sure, I kinda need money to stay alive so I'll take that) use windows or macos. Sure, apple seems to care about user privacy way more than other vendors but as long as nobody can verify that through source code, no offense, I won't believe a thing they say about that because no one can technically verify it anyways.

Some people have told me that Linux is hard to use for new/(highly) a-technical people but looking at my own family and friends who adapted fast as hell and don't want to go back to windows now (and mac, for that matter), I highly doubt that. Sure, they'll have to learn something new. But that was also the case when they started to use any other system for the first time. Possibly try a different distro if one doesn't fit?

Problems - sometimes hard to solve on Linux, no doubt about that. But, at least its open. Meaning that someone can dive in as deep as possible/necessary to solve the problem. That's something which is very difficult with closed systems.

The best example in this case for me (don't remember how I did it by the way) was when I mounted a network drive at boot on windows and Linux (two systems using the same webDav drive). I changed the authentication and both systems weren't in for booting anymore. Hours of searching how to unfuck this on windows - I ended up reinstalling it because I just couldn't find a solution.
On linux, i found some article quite quickly telling to remove the entry for the webdav thingy from fstab. Booted into a root recovery shell, chrooted to the harddrive, removed the entry in fstab and rebooted. BAM. Everything worked again.

So yeah, that's my view on this, I guess ;P

Today my manager asked me about my research into using RabbitMQ as a backup in case Azure Service Bus ever goes down.

Me: "Good. The way we designed the framework, all we have to do is drop the DLLs into the directory, update the config, and the services will start using RabbitMQ."
Mgr: "Excellent. Probably should be looking into using RabbitMQ as a permanent replacement for Azure"
Me: "What? The whole reason we moved to Azure was to eliminate the problems with having an on prem service bus. Since we've switched, there has been zero downtime."
Mgr: "That's what VP-Joe is afraid of. If Azure ever goes down, he won't know how to explain Azure to the president as to why we're not taking orders or can't ship packages."
Me: "That makes no sense. What did VP-Joe tell the president when a database goes down or a server mis-configuration?"
Mgr: "President understands internal outages, its just the whole 'cloud' thing he doesn't understand."
Me: "Um..then VP-Joe needs to explain it to him?"
Mgr: "The decision has already been made. Are you on board? Lets look at this move as a cost savings."
Me: "You mean the $10 a month? How much hardware will we need to support RabbitMQ?"
Mgr: "Yea, nobody probably thought of that."
Me: "I'm on board with whatever decision, but I'd like a little more than VP-Joe being afraid of the president."
Mgr: "I'm sure its not being afraid."
Me: "..."
Mgr: "OK, lets wait and see if VP-Joe forgets about this and moves on to something new."

I really, honestly, am getting annoyed when someone tells me that "Linux is user-friendly". Some people seem to think that because they themselves can install Linux, that anyone can, and because I still use Windows I'm some sort of a noob.

So let me tell you why I don't use Linux: because it never actually "just works". I have tried, at the very least two dozen times, to install one distro or another on a machine that I owned. Never, not even once, not even *close*, has it installed and worked without failing on some part of my hardware.

My last experience was with Ubuntu 17.04, supposed to have great hardware and software support. I have a popular Dell Alienware machine with extremely common hardware (please don't hate me, I had a great deal through work with an interest-free loan to buy it!), and I thought for just one moment that maybe Ubuntu had reached the point where it just, y'know, fucking worked when installing it... but no. Not a chance.

It started with my monitors. My secondary monitor that worked fine on Windows and never once failed to display anything, simply didn't work. It wasn't detected, it didn't turn on, it just failed. After hours of toiling with bash commands and fucking around in x conf files, I finally figured out that for some reason, it didn't like my two IDENTICAL monitors on IDENTICAL cables on the SAME video card. I fixed it by using a DVI to HDMI adapter....

Then was my sound card. It appeared to be detected and working, but it was playing at like 0.01% volume. The system volume was fine, the speaker volume was fine, everything appeared great except I literally had no fucking sound. I tried everything from using the front output to checking if it was going to my display through HDMI to "switching the audio sublayer from alsa to whatever the hell other thing exists" but nothing worked. I gave up.

My mouse? Hell. It's a Corsair Gaming mouse, nothing fancy, it only has a couple extra buttons - none of those worked, not even the goddamn scrollwheel. I didn't expect the *lights* to work, but the "back" and "Forward" buttons? COME ON. After an hour, I just gave up.

My media keyboard that's like 15 years old and is of IBM brand obviously wasn't recognized. Didn't even bother with that one.

Of my 3 different network adapters (2 connectors, one wifi), only one physical card was detected. Bluetooth didn't work. At this point I was so tired of finding things that didn't work that I tried something else.

My work VPN... holy shit have you ever tried configuring a corporate VPN on Linux? Goddamn. On windows it's "next next next finish then enter your username/password" and on Linux it's "get this specific format TLS certificate from your IT with a private key and put it in this network conf and then run this whatever command to...." yeah no.

And don't get me started on even attempting to play GAMES on this fucking OS. I mean, even installing the graphic drivers? Never in my life have I had to *exit the GUI layer of an OS* to install a graphic driver. That would be like dropping down to MS-DOS on Windows to install Nvidia drivers. Holy shit what the fuck guys. And don't get me started on WINE, I ain't touching this "not an emulator emulator" with a 10-foot pole.

And then, you start reading online for all these problems and it's a mix of "here are 9038245 steps to fix your problem in the terminal" and "fucking noob go back to Windows if you can't deal with it" posts.

It's SO FUCKING FRUSTRATING, I spent a whole day trying to get a BASIC system up and running, where it takes a half-hour AT MOST with any version of Windows. I'm just... done.

I will give Ubuntu one redeeming quality, however. On the Live USB, you can use the `dd` command to mirror a whole drive in a few minutes. And when you're doing fucking around with this piece of shit OS that refuses to do simple things like "playing audio", `dd` will restore Windows right back to where it was as if Ubuntu never existed in the first place.

Thanks, `dd`. I wish you were on Windows. Your OS is the LEAST user friendly thing I've ever had to deal with.

Who said programmers cannot solve hardware problems?

My router just said "Check hardware connection of your WAN port"

I took the cable out, blew in the socket and put it back in.

My internet is back in action.

Like car accidents, most hardware problems are due to driver error.

A room full of mostly old male stressed out engineers sat in chairs, and the presenter said:

"So who watched Judging Amy last night?"

The presenter went on to express her surprise that nobody in the room had seen last night's episode of Judging Amy.... and wasn't going to drop the topic.

The meeting, if it ever had any, now had no chance of going anywhere good.

By the end of the meeting someone would walk out and "retire" shortly there after, and it certainly wasn't going to be the presenter....

Backstory:

The company built on the IBM model of sell pricey custom hardware (granted it worked really well) and sell expensive support contracts wasn't doing as well as it had hoped. Granted it was still doing better than most of its neighboring companies, but it was clear that with the .com bust the days of catered lunches every day were over.

The company had grown fat and everyone knew that while the company had a good enough product(s) to survive, there weren't enough lifeboats for everyone to survive.

In the midst of this an HR department that took up nearly 20% of the office space at HQ felt it needed to justify its existence / expenses.

They decided to do this in the same way they always had, by taking funding from other departments, this time not by simply demanding more direct budgets for themselves.... they decided to impose mandatory 'training' on other departments ... that they would then bill for this training.

When HR got wind that there were some stressed out engineers the solution was, as it always is for HR.... to do more HR stuff:

They decided to take these time starved engineers away from their jobs, and put them in a room with HR for 4 days. Meanwhile the engineer's tasks, deadlines and etc remained the same.

Support got roped into it too, and that's how I ended up there.

It would be difficult to describe the chasm between HR and everyone else at that company. This was an HR department that when they didn't have enough cubes (because of constant remodeling in the HR area under the guise of privacy) sat their extra HR employees next to engineering and were 'upset' that the engineers 'weren't very friendly and all they did was work'.

At one point a meeting to discuss this point of contention was called off for some made up reason or another by someone with a clue.

So there we all sat, our deadlines kept ticking away and this HR team (3 people) stood at the front of the room and were perplexed that none of these mostly older males in this room had seen last night's episode of Judging Amy.

From there the presentation was chaos, because almost the entire thing was based on your knowledge of what happened to poor stressed out Amy ... or something like that.

We were peppered with HR tales of being stressed out and taking a long lunch and feeling better, and this magical thing where the poor HR person went and had a good cry with her boss and her boss magically took more off her plate (a brutal story where the poor HR person was almost moved to tears again).

The lack of apparent sympathy (really nobody said much at all) and lack of seeming understanding from the crowd of engineers that all they should do is take a long lunch, or tell their boss to solve their problems ... seemed to bother the HR folks. They were on edge.

So then they finally asked "What are your stressers?" And they picked the worst possible person they could to ask, Ted.

Ted was old, he prickly, he was the only one who understood the worst ass hell of assembly that had been left behind.

Ted made a mistake, he was honest with folks who couldn't possibly understand what he was saying. "This mandatory class is stressing me out. I have work to do and less time because of this class."

The exchange that followed was kinda horrible and I recall sitting behind Ted trying to be as small as possible as to not be called on. Exactly what everyone said almost doesn't matter.

A pedantic debate between Ted and the HR staff about "mandatory" and "required" followed. I will just sum it up that they were both in the wrong for how they behaved for a good 20 minutes...

Ted walked out, and would later 'retire' that week.

Ted had a history and was no saint. I suspect an email campaign by various folks who recounted the events that day spared ted the 'fired' status and he walked with what eventually would become the severance package status quo.

HR never again held another 'training', most of them would all finally face the axe a few months later after the CEO finally decided that 'customer facing, and product producing' headcount had been reduced enough ... and it was other internal staff's time for that.

The result of the meeting was one less engineer, and everyone else had 4 days less of work done...

Aren't most problems hardware ? 😛

After returning back from the company we were purchasing a new phone system (hardware+software, $100K+, kind of a big deal)
VP: “I need the new phone system software integration for our CRM by next week. I need to demo the system for the other VPs”
Me: “No problem. Were you able to get their API like I asked?”
VP: “Salesman didn’t know for sure what that was, but he said all the developer software documentation is on their site.”
Me: “Did he give you a URL? Their main site is all marketing mumbo-jumbo. I assume there is another one specific for developers.”
VP: “Yea, he might have said something, but I don’t understand why you need it. The salesman said the integration would be seamless. He showed me several demos.”
Me: “No, I mean I need to know, is the API a full client install? a simple dll? is this going to be a web service integration? How will I know what to program against?”
VP: “I think I heard him say something about COM? Does that sound like an API?”
Me: “It’s a start. Did he provide you anything, a disk, a flash drive, anything with the software?”
VP: “No, only thing he told me was our CRM integration would be seamless and our development team would have no problems.”
Me: “OK..OK…I get it…he’s a salesman. Is there an 1-800 number I can call? A technical support email address? Anyone technical I can reach out to?”
VP: “Probably, but I don’t understand what the problem is. I need the CRM integrated by next week. I gave the other VPs a promise we would get it done. I do not break promises.”
Me: “Wait…when are we installing the new system?”
VP: “Well, the purchase order will be cut at the end of the month’s billing cycle, the company has about a two month turnaround time to deliver and install the hardware, so maybe 3 months from now? Are you going to be able to have the integration ready for next week?”
Me: “If we won’t see any of the hardware for 3 months, what exactly am I integrating with?”
VP: “That API you wanted or whatever it is. COM…yea, it’s COM. I was told the integration would be seamless and our developers would have no problem. I don’t understand why you can’t simply write the code to make it work. Getting the hardware installed is going to be the hardest part.”
Me: “OK, so I have no documentation, we have no hardware, no software, and no idea what this ‘seamless integration’ means. I’m afraid there isn’t anything I can do right now. ”
VP: “Fine!...I’ll just have to tell the other VPs you were not able to execute the seamless integration with the CRM.”
Which he did. When the hardware+software was finally installed, they hired consultants (because I “failed”). I think the bill was in the $50K range to perform the ‘integration’ which consisted of Excel spreadsheets (no kidding). When approached with the primary CRM integration, the team needed our API documentation, a year’s development time and $300K. I was pissed off enough, and I had the API documentation, I was able to get the basic CRM integration within 3 days. When an agent receives a call, I look up the # in our database, auto-fill the form with the customer info, etc. Easy stuff when you have the documentation.
The basics worked and the VP was congratulated by ‘saving’ the company $300K. May or may not have been bonuses involved, rumors still out on that one, but I didn't see em'. Later my manager told me the VP was really ticked that I performed the integration ‘behind his back’, but because it was a success, he couldn’t fire me.

!rant
Just finished my CNC.
Lots of problems but it works... More or less.
Need better steppers and other drivers. But I did it, learned a lot, did lots of mistakes, and don't get me started on debugging hardware...
Z axis unfortunaly can't even pull the motor up lol.

My laptop started making faint high-pitched noises - I hope I misheard and it's actually just some coil singing inside the power-supply and not one of the disks/something else - also, I seem to have dropped 4GB of RAM suddenly where there should be 8GB.

(Also, I should really wipe the messed up dual-boot still residing on disk from last semester and replace it by a fresh arch-only install. (No time and joy in debugging that right now.) Probably something for tomorrow evening.)

The device is ~8 years old by now and starting to fall apart - nothing duct tape can't fix - but I'm somewhat worried about the rest right now. D:

Meh, I really need that laptop during the next two weeks, I just hope the hardware doesn't die on me in the meantime because I can't wait for an order to arrive, let alone afford some cheap replacement.

I just found a game (have not played it yet) that I think everyone here will cream over.

It's an insanely detailed hardware/ low level/ make-your-own-computer game.

I watched the trailer and it sets you up by teaching you logic gates and basic circuitry.

Then, it eventually teaches you how to build your own computer using these gates.

Then, you start creating your own assembly language using the computer you made.

Then, you use your computer to solve problems like sending a robot through a maze or just building snake on a display.

Absolutely check it out, it's on sale for $13 USD. I just bought it. Turing Complete on Steam.

Help.

I'm a hardware guy. If I do software, it's bare-metal (almost always). I need to fully understand my build system and tweak it exactly to my needs. I'm the sorta guy that needs memory alignment and bitwise operations on a daily basis. I'm always cautious about processor cycles, memory allocation, and power consumption. I think twice if I really need to use a float there and I consider exactly what cost the abstraction layers I build come at.

I had done some web design and development, but that was back in the day when you knew all the workarounds for IE 5-7 by heart and when people were disappointed there wasn't going to be a XHTML 2.0. I didn't build anything large until recently.

Since that time, a lot has happened. Web development has evolved in a way I didn't really fancy, to say the least. Client-side rendering for everything the server could easily do? Of course. Wasting precious energy on mobile devices because it works well enough? Naturally. Solving the simplest problems with a gigantic mess of dependencies you don't even bother to inspect? Well, how else are you going to handle all your sensitive data?

I was going to compare this to the Arduino culture of using modules you don't understand in code you don't understand. But then again, you don't see consumer products or customer-specific electronics powered by an Arduino (at least not that I'm aware of).

I'm just not fit for that shooting-drills-at-walls methodology for getting holes. I'm not against neither easy nor pretty-to-look-at solutions, but it just comes across as wasteful for me nowadays.

So, after my hiatus from web development, I've now been in a sort of internet platform project for a few months. I'm now directly confronted with all that you guys love and hate, frontend frameworks and Node for the backend and whatever. I deliberately didn't voice my opinion when the stack was chosen, because I didn't want to interfere with the modern ways and instead get some experience out of it (and I am).

And now, I'm slowly starting to feel like it was OKAY to work like this.

Microsoft Office Sharepoint Server.

There is no technology on Earth that speaks worse of Microsoft than is this crap. Nothing they ever made (not even Comic Sans) is as bad as Sharepoint.

No proper editor. Everything is slooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooow. To run it you need a state-of-the-art server. There is no way to make the UI modern, as Sharepoint itself is built upon 1995 era HTML. Tables in tables in tables in tables in tables. And even if you do a web part that's readable, it will be wrapped in shit and presented to the client anyway.
It's so easy to break too. Most of the time I was just watching why the fuck it didn't work. Huge problem with caching as well. Deploying any change requires 10 minutes of manual labor.

I get why companies want to use it. Out of the box it's got quite a few very nice features, and aside from the problems setting it up, and hardware requirements, it works decently well.

But I won't come near it unless I'm paid 100$ per hour or starving to death.

Do you know when you think "Oh that doesn't look too hard. I bet I can do it in no time"?
That is how I felt when I saw the DIY 3D printer kit Anet A8. It's only 150€ on gearbest so that is pretty cheap.
The reviews said it takes about 3 - 4 hours to build and I though "Ok I am a computer specialist and engineer so 3h sounds reasonable".
When I bought it from gearbest the first problems started: 5 days after the estimated shipping date the packet was still not on its way. After I fucked the support up, it finally arrived 3 weeks after the estimated date.
When I took the first look, everything seemed to be fine except for some small scratches but for that price that is not a problem.
So I started to build the printer at about 14:00 and even if some random sites in the manual were in Chinese I felt confident to get it done in a view hours.
And then it started to get really fucked. The first problem was that 2 screws were unusable and I had to use my own screws instead. The next problem was that the manual was just in the wrong fucking order at some points and I had to reverse multiple steps to get it right.
But the most fucked up thing: There should have been 2 threaded rods with a length of 345mm but the rods had a length of 310mm which was nowhere listed in the parts list. So I had to go buy some aluminium rods to fill the gap temporary so that I can at least go on with the build before getting a replacement. And I could go on and on and with the problems but the point is, it is now 19:30 which is about 5.5 hours after I started and I am still not fucking done with this.

So what have I learned?
Cheap Chinese hardware is good, but only as long as you don't have to assemble that shit yourself.

TLDR: There’s truth in the motto “fake it till you make it”

Once upon a time in January 2018 I began work as a part time sysadmin intern for a small financial firm in the rural US. This company is family owned, and the family doesn’t understand or invest in the technology their business is built on. I’m hired on because of my minor background in Cisco networking and Mac repair/administration.

I was the only staff member with vendor certifications and any background in networking / systems administration / computer hardware. There is an overtaxed web developer doing sysadmin/desktop support work and hating it.

I quickly take that part of his job and become the “if it has electricity it’s his job to fix it” guy. I troubleshoot Exchange server and Active Directory problems, configure cloudhosted web servers and DNS records, change lightbulbs and reboot printers in the office.

After realizing that I’m not an intern but actually just a cheap sysadmin I began looking for work that pays appropriately and is full time. I also change my email signature to say “Company Name: Network Administrator”

A few weeks later the “HR” department (we have 30 employees, it’s more like “The accountant who checks hiring paperwork”) sends out an email saying that certain ‘key’ departments have no coverage at inappropriate times. I don’t connect the dots.

Two days later I receive a testy email from one of the owners telling me that she is unhappy with my lack of time spent in the office. That as the Network Administrator I have responsibilities, and I need to be available for her and others 8-5 when problems need troubleshooting. Her son is my “boss” who is rarely in the office and has almost no technical acumen. He neglected to inform her that I’m a part time employee.

I arrange a meeting in which I propose that I be hired on full time as the Network Administrator to alleviate their problems. They agree but wildly underpay me. I continue searching for work but now my resume says Network Administrator.

Two weeks ago I accepted a job offer for double my current salary at a local software development firm as a junior automation engineer. They said they hired me on with so little experience specifically because of my networking background, which their ops dept is weak in. I highlighted my 6 months experience as Network Administrator during my interviews.

My take away: Perception matters more than reality. If you start acting like something, people will treat you like that.

A colleague of mine had to debug performance problems in a foreign, proprietary application that is ancient.

To be crystal clear: Only reason that thing exists is because some old geezers fear change.

Asked me for help cause it's an _ancient_ MS SQL server that is luckily running on hardware owned by us.

Finding the credentials was already a funny task.

We had to access the vault (not joking here, we have a physical vault for storing sensitive data and critical backups), grab a folder and find the necessary data cause no one ever dares to touch that thing.

The application is btw for a sort of ERP / inventory system that is used in some ancient shops not yet migrated...

Yeah. Story speaks for itself.

Anyway, after dusting off ourselves, we were able to connect.

Was a bit ... Interesting. Everything's in german. The worst kind of german.

After looking at the first tables, I started giggling.

My colleague knew immediately that this was a sign of danger (insert Simpson meme here), raised his eyebrows and asked "How bad is it....".

Me, still giggling, "lemme take a further look, this is gold".

*long sigh from the colleague*

Well... It ended with me putting my hands in front of my eyes, turning around and saying: "I cannot look at it anymore, it hurts too much...."

To summarize:
- German table names
- When a table exceeded 300 plus columns, they added another table with the same plus suffix "_ddd"… where ddd is an zero filled integer sequence like 001
- To join this mess, they created views... Named "generator" - Sequence Number ... Some had the beginning of table names appended, which doesn't make it less confusing.
- the process list was listing queries running longer than 5 mins.

Which isn't at all surprising when generating carrtesian products of N tables with left join.

I've seen shit.... I've seen a lot of shit.

But that shit scared me.

Alright, this my fucking rant right here. Distraction? This whole company is a distraction! Boss decided to throw us all in an open work environment doing jobs that require careful concentration. Straight outta college I'm getting handed vague ideas, (make a desktop app that helps our customers put data on the internet, make an iPhone app) with out so much as an inkling of what technologies to use, just make it work.
Ok I will but when you hit a roadblock with very little resources to draw in it's hard to stay focused.
On top of that since I worked in support for a year I'm our senior support person! But sometimes support just doesn't use their brains and I'm using my time to solve very basic problems.
That brings me to my next point, the goddamn piece of shit that is our telephone. Fuck that thing when it rings it's never good. Moreover, since I don't want to get roasted for not being responsive I have the motherfucker forward to my personal cell. So I answer every fucking call and I get so many spam calls!
Not to mention I'm mainly running the hardware show around here. Shits broke I'm the one fixing it. Need new shit I'm putting the order together.
Tried to get a new guy to be the sys admin, ordered a 6th gen board with a 7th gen proc, had to pull 3 machines apart to get that sorted. Then he left bc family issues, and has been gone for weeks.
The other devs are also slam up busy, and the main product is about 15 people's piss on a plate of garb age spaghetti. (I got a lot of shit going on but at least I'm the only one pissing in my spaghetti) it's a constant run around if who does what with a code first plan later mentality causing confusion and delay.
Nobody wants to help anybody because they are also annoyed with this setup and are getting bitched at by customers or management.
Sales is mostly composed of a bunch of crackhead yes men and women who just want a commission and only half know the shit we sell and have sold 15 new features that had not been discussed. But management always says make it happen. In what priority? It's all a priority they say! Wtf.
So yea, then it brings me to me, dealing with this much chaos at work makes it seem like a high amount of chaos in my life is normal. I'm just now learning to control this.
I've had to do a lot of growing up as a person and as a developer. I've went from being the most junior to about the 3rd most seniors and I've no doubt my efforts have contributed to the growth of the company.
I'm a big believer in coding flow, and that it takes at least 15 mins to get in that flow and about 5 seconds to break it. There is no do not disturb on the company chat, everything always on fire it seems.
So fuck a lot of this, but I've done the research and where I'm at is the best opportunity in a 100 mile radius. So I am thankful for this job. Plus I usually win the horror story contest.

So TL;DR the biggest distraction is every fucking thing in this god forsaken place.

Hey guys.
Arduino + Bluetooth + L293D + car Chacis and 4 DC motors.

Finaly finished my second bot/Drone.
Actually finished it yesterday but had lots of problems with hardware bugs (learned so fucking much in a day).
Tought I fucked two unos with bad soldering... No they are fine, just won't turn on in the circuit that was already working (was fine running the code).
Redone everything from scratch with a arduino uno, it's perfect now.

Funniest part is how I got my hands on a 50€ car kit for almost free... So some Chinese store sended this kit instead of some cheap stuff. Saved another arduino with the chip rack (that one that you can trade the atmega chip), I'll save it to program single chips. Plus a h bridge and lot lot more cool stuff.
Used only the Chacis.
Next: esp8266 and camera... And maby a gun? Would be cool

Best code performance incr. I made?

Many, many years ago our scaling strategy was to throw hardware at performance problems. Hardware consisted of dedicated web server and backing SQL server box, so each site instance had two servers (and data replication processes in place)

Two servers turned into 4, 4 to 8, 8 to around 16 (don't remember exactly what we ended up with). With Window's server and SQL Server licenses getting into the hundreds of thousands of dollars, the 'powers-that-be' were becoming very concerned with our IT budget. With our IT-VP and other web mgrs being hardware-centric, they simply shrugged and told the company that's just the way it is.

Taking it upon myself, started looking into utilizing web services, caching data (Microsoft's Velocity at the time), and a service that returned product data, the bottleneck for most of the performance issues. Description, price, simple stuff. Testing the scaling with our dev environment, single web server and single backing sql server, the service was able to handle 10x the traffic with much better performance.

Since the majority of the IT mgmt were hardware centric, they blew off the results saying my tests were contrived and my solution wouldn't work in 'the real world'. Not 100% wrong, I had no idea what would happen when real traffic would hit the site.

With our other hardware guys concerned the web hardware budget was tearing into everything else, they helped convince the 'powers-that-be' to give my idea a shot.

Fast forward a couple of months (lots of web code changes), early one morning we started slowly turning on the new framework (3 load balanced web service servers, 3 web servers, one sql server). 5 minutes...no issues, 10 minutes...no issues,an hour...everything is looking great. Then (A is a network admin)...
A: "Umm...guys...hardly any of the other web servers are being hit. The new servers are handling almost 100% of the traffic."
VP: "That can't be right. Something must be wrong with the load balancers. Rollback!"
A:"No, everything is fine. Load balancer is working and the performance spikes are coming from the old servers, not the new ones. Wow!, this is awesome!"
<Web manager 'Stacey'>
Stacey: "We probably still need to rollback. We'll need to do a full analysis to why the performance improved and apply it the current hardware setup."
A: "Page load times are now under 100 milliseconds from almost 3 seconds. Lets not rollback and see what happens."
Stacey:"I don't know, customers aren't used to such fast load times. They'll think something is wrong and go to a competitor. Rollback."
VP: "Agreed. We don't why this so fast. We'll need to replicate what is going on to the current architecture. Good try guys."
<later that day>
VP: "We've received hundreds of emails complementing us on the web site performance this morning and upset that the site suddenly slowed down again. CEO got wind of these emails and instructed us to move forward with the new framework."

After full implementation, we were able to scale back to only a few web servers and a single sql server, saving an initial $300,000 and a potential future savings of over $500,000. Budget analysis considering other factors, over the next 7 years, this would save the company over a million dollars.

At the semi-annual company wide meeting, our VP made a speech.

VP: "I'd like to thank everyone for this hard fought journey to get our web site up to industry standards for the benefit of our customers and stakeholders. Most of all, I'd like to thank Stacey for all her effort in designing and implementation of the scaling solution. Great job Stacy!"
<hands her a blank white envelope, hmmm...wonder what was in it?>

A few devs who sat in front of me turn around, network guys to the right, all look at me with puzzled looks with one mouth-ing "WTF?"

Was forced to do some work on Windows this week (CAD tools that runs only on Windows). I spent a few days just setting up the tools. There were quite a few things I realized I forgot about Windows (as compared to Linux).

1) Installation times are down right horrific. What exactly are the installer doing for 10 minutes?
2) .NET is a cluster fuck. Not even Microsofts repair tool can fix it, but rather just hangs. I ended up using another tool to nuke it and reinstall.
3) Windows binary installs are insanely huge, thus, takes forever to download.
4) The registry is a pointless database that must have been written in hell with the single intent of destroying users will to live. The sole existence of the registry is another proof that completely incompetent engineers designed Windows.
5) Rebooting is the only way to solve many problems. This is another sure sign of a fundamentally fucked up OS design.
6) What the heck is wrong with the GUIs designers? The control panel must be the worst design ever. There are so many levels to get to a particular setting I'm getting dizzy. Nothing gets better by the illogical organisation.
7) Windows networking. A perversion of the tcp/ip stack that makes it virtually impossible to understand a damn thing about the current network configuration. There are at least 3 different places that effects the settings.
8) Windows command prompt. Why did they even bother to leave it in? The interpreter is as intelligent as retarded donut. You can't do anything with it, except typing "exit" and Google for another solution.
8) Updates. Why does it takes hundreds of updates per month to keep that thing safe?
9) Despite all updates that is flying out of Redmond like confetti, it is still necessary to install antivirus to keep the damn thing safe. That cost extra money, and further cost you by degrading performance of your hardware.
10) Window performance. Software runs like it was swimming in molasses. The final stab in the back on your hardware investment, and pretty much sends performance on your hardware back a few hundred bucks more.
11) Closed source is evil. If something crash consistently, you might find a forum that address the issues you have. Otherwise you're out of luck. On the other hand, it might be for the better. I imagine reading the code for Windows can lead to severe depression.

I'm lucky to be a Linux dev, and should probably not complain too much... But really, Windows, go get yourself hit by a truck and die. I won't miss you.

Worst thing you've seen another dev do? Here is another.

Early into our eCommerce venture, we experienced the normal growing pains.

Part of the learning process was realizing in web development, you should only access data resources on an as-needed basis.

One business object on it's creation would populate db lookups, initialize business rule engines (calling the db), etc.

Initially, this design was fine, no one noticed anything until business started to grow and started to cause problems in other systems (classic scaling problems)

VP wanted a review of the code and recommendations before throwing hardware at the problem (which they already started to do).

Over a month, I started making some aggressive changes by streamlining SQL, moving initialization, and refactoring like a mad man.

Over all page loads were not really affected, but the back-end resources were almost back to pre-eCommerce levels.

The main web developer at the time was not amused and fought my changes as much as she could.

Couple months later the CEO was speaking to everyone about his experience at a trade show when another CEO was complementing him on the changes to our web site.
The site was must faster, pages loaded without any glitches, checkout actually worked the first time, etc.
CEO wanted to thank everyone involved etc..and so on.

About a week later the VP handed out 'Thank You' certificates for the entire web team (only 4 at the time, I was on another team). I was noticeably excluded (not that I cared about a stupid piece of paper, but they also got a pizza lunch...I was much more pissed about that). My boss went to find out what was going on.

MyBoss: "Well, turned out 'Sally' did make all the web site performance improvements."
Me: "Where have you been the past 3 months? 'Sally' is the one who fought all my improvements. All my improvements are still in the production code."
MyBoss: "I'm just the messenger. What would you like me to do? I can buy you a pizza if you want. The team already reviewed the code and they are the ones who gave her the credit."
Me: "That's crap. My comments are all over that code base. I put my initials, date, what I did, why, and what was improved. I put the actual performance improvement numbers in the code!"
MyBoss: "Yea? Weird. That is what 'Tom' said why 'Sally' was put in for a promotion. For her due diligence for documenting the improvements."
Me:"What!? No. Look...lets look at the code"

Open up the file...there it was...*her* initials...the date, what changed, performance improvement numbers, etc.

WTF!

I opened version control and saw that she made one change, the day *after* the CEO thanked everyone and replaced my initials with hers.

She knew the other devs would only look at the current code to see who made the improvements (not bother to look at the code-differences)

MyBoss: "Wow...that's dirty. Best to move on and forget about it. Let them have their little party. Let us grown ups keeping doing the important things."

Damn maintenance windows. I mean, I get that the SaaS product my boyfriend works on can't go out in the middle of the day. But he just spent weeks on a business trip, with an absolutely mad sleep schedule because he's redesigning their data center (or something. Don't ask me, it's a hardware problem...) and now he's finally coming home today and I'm super excited but all he's going to want to do this weekend is sleep. Even though I'd love to spend Sunday going to this yearly event, or finally getting another round of DnD in (everyone else in the group is available). But nope. Bloody all-hours work is taking away his (and thus my) weekend too.

TL;DR; windows XP + bat scripts + fascination about being able to make things yourself.

I was born and raised in a village. And the thing about living in a village is that you are free :) Among all the other freedoms you are also free to build your own solutions to various domestic problems, i.e. to build stuff. This is one of the things that fascinates me about living outside the city.

When I finally was old enough (and had the means to, i.e. a computer) to understand that programming is something that allows you to build your own solutions to computer problems, it got to me.

With win 3.1 I was still too fresh and too young. With win 95 I was more interested in playing with neighbours outdoors. With win 98 I was a bit too busy at school. But with win XP the time had come. I started writing automation solutions for windows administration using .bat scripts (.vbs was and still is somewhat repelling to me). I no longer needed to browse Russian forums and torrent sites to find a solution to a problem I had! That was amazing!!! [esp. when my Russian was very weak].

That was the time when I built my first sort-of-malware - a bat script downloading and installing Radmin server, uploading computer's IP and admin credentials to my FTP.

I loved it!

However, I'd stumbled upon may obstacles when writing with batch. I googled a lot and most of the solutions I found were in bash (something related to Linux, which was a spooky mystery to me back then). Eventually, I got my courage together and installed ubuntu. Boy was I sorry... Nothing was working. I was unable to even boot the thing! Not to mention the GUI...

Years later I tried again with ubuntu [7.10 I think.. or 7.04] on my Pavilion. Took me a looooot of attempts but I got there. I could finally boot it. A couple of weeks later I managed to even start the GUI! I could finally learn bash and enjoy the spectacular Compiz effects (that cube was amazing).

I got into bash and Linux for the next several years. And then I thought to myself - wait, I'm writing scripts that automate other programs. Wouldn't it be cool I I could write my own programs that did exactly what I wanted and did not need automation? It definitely would! I could write a program that would make sound work (meaning no more ALSA/PA headaches!), make graphics work on my hardware, make my USB audio card to be set to primary once connected and all the other amazing things! No more automation -- just a single program or all of that!

little did the naive me knew :)

I started with python. I didn't like that syntax from the beginning :/ those indentations...

Then I tried java. Bucky (thenewboston), who likes tuna sandwiches, on my phone all the free time I had. I didn't learn anything :/ Even tried some java 101 e-book. Nothing helped until I decided to write some simple project (nothing fancy - just some calculations for a friend who was studying architecture).

I loved it! It sounds weird, but I found Swing amazing too. With that layout manager where you have to manually position all the components :)

and then things happened and I quit my med studies and switched to programming. Passed my school exams I was missing to enter the IT college and started inhaling every bit of info about IT I could get my hands on (incl outside the college ofc).

A few more stepping stones, a few more irrelevant jobs to pay my bills in the city, and I got to where I am now.

I started to hate programming.
I started with a lot of enthusiasm 11 years ago up to become in 2 years a full stack dev, a sysadmin and had also my fair share of technical assistance on every device plus hardware experience mounting hardware like cctvs, routers, extenders, industrial printers and so on. At the time you actually had the tools to solve problems and had to crack your head and pull hairs to solve stuff and people actually was developing solution and frameworks that solved stuff.

Today I can't stand anything.

Every midschooler feels entitled to release a framework that is announed as the next cure for cancer. Web dev once was thin and simplistic, now simplicity is considered a bug and not a feature.
I'm working on an angular project for the nth time and the whole environment is a clusterfuck of problems held togheter with kids glue.
Someone did a tool/framework for everything but most of it is barely well tested or mature.

Just to start this project we had to know, beside html/css/js techs like Angular, Kafka, Kubernetes, Docker, git, Lit, npm/node, mysql/sql server, webpack/grunt and the hell that it brings, C#/Asp.NET/MVC/WebAPI, and so on, the list is long.

DAMN. Making a simple page which shows a tabbed view with some grids requires you to know a whole damn stack of technologies that need to cooperate togheter.
It's 10x more complex and I actually find it much less productive than ever.

But what bugs me most, is that 90% of that stuff is bug ridden, has some niche use case or hidden pitfall and stuff because with this whole crap of "hey we put on github you open a ticket" they just release spaghetti code and wait for people to do the debug for them.

Angular puts out a version every 2 days and create destructive updates.

I am so tired that I spend most of my 8hrs binging youtube vids in despair to procrastinate work.
I liked to do this once....

After using linux as the main os for the last two weeks, here are the biggest drawbacks of linux in my opinion.

1. AMD hybird apus are not supported by linux kernal and it's very lousy.

2. Cannot do any graphics related work without having my screen going black several times.

3. Using dual screen is not reliable, and black screen occurs in one or both screens.

4. The computer goes crazy after waking up from suspend mode and gets overheated!

5. Kernal updates! Is much worse than Windows updates. At least after the painful windows update restart you know everything will be ok, but with linux good luck!!!

6. Realtek Wifi dongles still suffering since 2010.

In my opinion, if you are going to use linux for the first time make sure your hardware is compatible with linux, else be ready for a fight of unstable hardware problems.

I just fucking hate BGAs* that unsolder themselves.

So, thanks to my laptop slowly breaking apart I decided to reactivate an old netbook my father gave me back in 2014(?) when it failed, to have a device on standby if necessary.

Wasn't really planning to repair it and kept it for spare parts mostly as the whole device is a fucking design failure concerning heat dissipation.

But yet again, I thought I'd give it a try one-two years ago. I soon found out it was said heat problem that caused the error in the device and it'd probably only take some reworking using a heat gun, which I did. Netbook worked for some hours, then was dead again, same error. Lost motivation and stashed it until this week.

Reworked with a hair-dryer this time and it worked! Well, until this morning - same error. Perhaps I shouldn't have tried to run a VM and then shut down the device right after that.

I will now try only one more time, this time just baking the whole damn main board thoroughly.
Either it works or it's really dead after. Either way, I'll be somewhat happier then.

* Ball Grid Array - package type for electronic components like ICs/uControllers

Me: Startup initialization tests fail so the system won't boot properly it until we fix those issues.

Manager: comment out the lines of code that are causing problems.

🤔 So we are just going to feed power to some hardware and see what happens I guess

It’s so great to hear Apple is finally officially making the transition to rolling out their own silicon on everything... fucken fabulous. Sure there may be problems at first but this might just get the ball rolling to get more companies todo the same... we need to eliminate the silicon monopolies... ARM and rolling your own is the future... well it always use to be the standard... back in the day, until the whole modularity and lean manufacturing and order off the shelf shit came about .... but finally we have once again come full circle back to where things use to be.... pairing hardware with software fucken beautiful LOVE IT!!!

Sure this will affect portability but .... guess what folks... means more jobs for us... quit being lazy and complaining about having to work..

Love vertical integration!!!!

Most successful? Well, this one kinda is...

So I just started working at the company and my manager has a project for me. There are almost no requirements except:
- I want a wireless device that I can put in a box
- I want to be able to know where that device is with enough accuracy to be able to determine in which box the device was put in if multiple boxes were standing together

So, I had to make a real time localization system. RTLS.
A solo project.

Ok, first a lot of experiments. What will the localization technique be? Which radio are we going to use?
How will the communication be structured?

After about two months I had tested a lot, but hadn't found THE solution. So I convinced my manager to try out UWB radio with Time Difference Of Arrival as localization technique. This couldn't be thrown together quickly because it needed more setup.

Two months later I had a working proof of concept. It had a lot of problems because we needed to distribute a clock signal because the radio listeners needed to be sub-nanosecond synchronous to achieve the accuracy my manager wanted. That clock signal wasn't great we later found out.

The results were good enough to continue to work on a prototype.
This time all wired communication would be over ethernet and we'd use PTP to synchronize the time.

Lockdown started.

There was a lot of trouble with getting the radio chip to work on the prototype, ethernet was tricky and the PTP turned out to be not accurate enough. A lot of dev work went into getting everything right.

A year and 5 hardware revisions later I had something that worked pretty well!
All time synchronization was done hybridly on the anchors and server where the best path to the time master was dynamically found.

Everything was synchronized to the subnanosecond. In my bedroom where I had my test setup I achieved an accuracy of about 30cm in 3d. This was awesome!

It was time to order the actual prototype and start testing it for real in one of the factory halls.

The order was made for 40 anchors and an appointment was made for the installation in the hall.

Suddenly my manager is fired.

Oh...
Ehh... That sucks. Well, let's just continue.

The hardware arrives and I prepare everything. Everything is ready and I'm pretty nervous. I've put all my expertise in this project. This is gonna make my career at this company.

Two weeks before the installation was to take place, not even a month after my manager was fired, I hear that my project was shelved.

...
...

Fuck

"We're not prioritizing this project right now" they said.

...

It would've been so great! And they took it away.
Including my salary and hardware dev cost, this project so far has cost them over €120k and they just shelved it.

I was put on other projects and they did try to find me something that suited me.

But I felt so betrayed and the projects we're not to my liking, so after another 2-3 months I quit and went to my current job.

It would've so nice and they ruined it.
Everything was made with Rust. Tags, anchors, RTLS server, web server & web frontend.

So yeah, sorry for the rambling.

Sometimes I have to work with physical hardware. There are over 300 machines in our lab, split among two subnets. But for some reason, I can never access my machines by hostnames.

Every other week, there's an IP conflict on this network, requiring me to log into the active directory server and delete old DNS entries. This usually happens because someone decided to deploy 64 VMs on a huge server, all at once, didn't boot them with a delay, let alone with with a warning to IT.

Then when my superior asks how my progress has been and I respond with "I can't even get the machines to ping each other by hostname, there's something wrong with the DNS:, I get the following response: "HOW COME NOBODY ELSE IS HAVING PROBLEMS WITH THIS. YOU'RE FULL OF SHIT", from someone who spends 90% of the year abroad, working remotely.

Ran Windows RAM diagnostic tools because I was too lazy to get my Linux USB-stick. Ran for 20 minutes, restarted - "There are hardware problems present."

NO SHIT. No info how many errors, no log file mentioned, no code or anything. Something happened. How retarded can a diagnostic tool be?

Guess laziness gets you punished immediately...

tl;dr - install ‘Pop!_os’ and try it out if you haven’t yet, it’s pretty damn good!

Heavy Micro$haft user here, have tried using ubuntu a bunch of times in the past and fucking regretted it every time. Ran into issues with stupid shit like the apt cache growing exponentially until the drive was full, or something like the the system python getting borked.

To be fair, I’m 120% certain my dumb-assery is what caused the problems. I’m definitely not trying to blame the OS. But my experience was shitty, even if it was at my own hands lol.

Started playing around with Pop!_os from the system76 team. And I’m seriously in freakin’ love with this OS. It’s clean, is performant, feels way less buggy or just feels more stable somehow. I know it’s based on ubuntu, but I’ve had a great time thus far using it. I’ve got ansible, docker, aws toolkit, aws cli, sam-cli, vscode, dynamodb-local, serverless, npm, brew, and working on steam now.

Everything has been a breeze and again the system feels really fast and snappy. It feels a lot like mac on the smoothness scale, but snappy like a windows box with beefy hardware specs.

I’m still just in the testing phase on a VM, but I’m seriously thinking about blowing away my windows install for Pop!_os.

(I’ll try arch someday when I’m up for some hardcore masochism)

Goddamnit I am an idiot. I just fried a microcontroller because I didnt have the right power supply and I used it anyway because fuck it, right? So now I am not a single step closer to the thing I was trying to do but I fucked up my hardware and it is a huge pain in the ass until I get a new one and figure out all the problems with it. Arghn

So I'm working our remote build/testing server, and all of a sudden my computer just turns off. No crash message, no error, just turned off. My co-worker tries to help troubleshoot the problem.

Nothing.

I take the computer downstairs to the hardware department. They plug it in and it starts no problems.

After it finishes updating, I take it back upstairs and plug it back in.

Nothing.

I suggest that it is the power cable, and my co-worker looks under his desk. Turns out he had kicked the switch on the surge protector. 😑

Aren't you, software engineer, ashamed of being employed by Apple? How can you work for a company that lives and shit on the heads of millions of fellow developers like a giant tech leech?
Assuming you can find a sounding excuse for yourself, pretending its market's fault and not your shitty greed that lets you work for a company with incredibly malicious product, sales, marketing and support policies, how can you not feel your coders-pride being melted under BILLIONS of complains for whatever shitty product you have delivered for them?
Be it a web service that runs on 1980 servers with still the same stack (cough cough itunesconnect, membercenter, bug tracker, etc etc etc etc) incompatible with vast majority of modern browsers around (google at least sticks a "beta" close to it for a few years, it could work for a few decades for you);
be it your historical incapacity to build web UI;
be it the complete lack of any resemblance of valid documentation and lets not even mention manuals (oh you say that the "status" variable is "the status of the object"? no shit sherlock, thank you and no, a wwdc video is not a manual, i don't wanna hear 3 hours of bullshit to know that stupid workaround to a stupid uikit api you designed) for any API you have developed;
be it the predatory tactics on smaller companies (yeah its capitalism baby, whatever) and bending 90 degrees with giants like Amazon;
be it the closeness (christ, even your bugtracker is closed and we had to come up with openradar to share problems that you would anyway ignore for decades);
be it a desktop ui api that is so old and unmaintained and so shitty, but so shitty, that you made that cancer of electron a de facto standard for mainstream software on macos;
be it a IDE that i am disgusted to even name, xcrap, that has literally millions of complains for the same millions of issues you dont even care to answer to or even less try to justify;
be it that you dont disclose your long term plans and then pretend us to production-test and workaround-fix your shitty non-production ready useless new OS features;
be it that a nervous breakdown on a stupid little guy on the other side of the planet that happens to have paid to you dozens of thousands of euros (in mandatory licences and hardware) to actually let you take an indecent cut out of his revenues cos there is no other choice in a monopoly regime, matter zero to you;
Assuming all of these and much more:
How can you sleep at night with all the screams of the devs you are exploiting whispering in you mind? Are all the money your earn worth?

** As someone already told you elsewhere, HAVE SOME FUCKING PRIDE, shitty people AND WRITE THE FUCKING DOCS AND FIX THE FUCKING BUGS you lazy motherfuckers, your are paid more than 99.99% of people on earth, move your fucking greasy little fingers on that fucking keyboard. **

PT2: why the fuck did you remove the ESC key from your shitty keyboards you fuckshits? is it cos autocomplete is slower than me searching the correct name of a function on stackoverflow and hence ESC key is useless? at least your hardware colleagues had the decency of admitting their error and rolling back some of the uncountable "questionable "hardware design choices (cough cough ...magic mouse... cough golden charging cables not compatible with your own devices.. cough )?

How to compare fan speeds: hold your finger in and compare how high pitched the sound is.

Okay, so yesterday was crazy. So crazy, in fact, that I'm not even typing this on my phone. I'm typing it on an LG G4.

So, I took an Uber out to a Sprint store I'd been told did repairs. My phone's vibrator was broken. So, basically I thought just like that R&M episode "20 minutes adventure in and out" - only to find out they'd need to wipe my goddamn phone, and then send it to Texas. I now have to wait 6 days for my phone lmfao.

So, in the meantime, they took an hour to get me this G4 which makes me miss all the finer things in life - I miss my USB-C and not having to give a damn about how I plug it in and I miss my fingerprint reader (I know, I'm a lazy fuck with first-world problems. I don't care to hear about how fucking stupid I am for either of those thoughts, STFU). Also the G4 is prone to hardware failures, so they said they weren't too happy about giving me this, but it's the only one with NFC.

So in the middle of setup, the Sprint store's power went out. FUUUUUUCK. The phone was pretty much at 5% battery and was being slow as hell, so you can just about imagine the irritation me and this guy had when the phone died in the middle of setup.

The next thing is an unrelated story, but I'm sure some of you older guys here will love this. I was at a place called Triangle Park last night. I go there for burgers, but they also have a bar. Sometimes I get sent to the bar and the bartender gets me my food. So last night I went to pick the food up from the bar for takeout.

The bartender must've had an accident and messed something up, so she told me to sit at the bar. I thought it was obvious I was only 19, so I barely sat. I'm literally not old enough to sit at the bar, even though when I was younger my dad and his friends used to let me sit with them because I had a history of saying stupid shit that made his friends laugh. Nonetheless, I sat with my ass hanging off the edge because I knew it was wrong :/

She comes back and asks what type of drink I want. I had to tell her that I was 19. I wasn't gonna sit here and lie because I'm pretty sure she could've lost her job for serving a minor. I exited and waited in the lobby.

But are we at the point where 19-year-olds look like 25-year-olds? I don't want to think about this because it means I'm getting older. That's a lot to take in. Later in the night it was still gnawing at my gut.

Yesterday was one hella day man.

What the hell has happened to Hewlett Packard?
They used to make the best notebooks around. 10-15 Years ago, basically all notebooks my family bought were from HP. These devices lasted for at least 6-8 years each.
Now I have a fucking expensive OMEN series notebook failing after 2 years with the most embarrasing hardware problems: Once a shielded piece of plastic from the bottom broke off and made a short on the mainboard, next time the way too thin power line that goes from the power plug to the PCB was placed alongside a sharp metal piece that damaged the isolation and again produced a short. When the display is moved, the webcam disconnects, which is also a hint at the production quality.
From my daughter's HP notebook the Display just broke off after like 18 months of use. When we brought it to service I asked the guy whether this happens a lot, he was like "I have 6 other notebooks of that type with the same problem in repair right now". After a repair that took forever because they couldn't get the proper replacement parts, the integrated webcam has died.
Never ever going to buy anything from this shitbrand again.

Well, I've been reading 'rants' in this community, and I'm amazed at how people discuss various softwares, languages, and sometimes even hardware!
I'd say I'm a noob. Can't even compare my 'coding knowledge' with what people know in this community, and I don't want to. I like that I'm now a part of this community. But I feel intimidated at times by the amount of things there are to learn! And I don't know how to start. I mean, we had a course on C for a semester, and I tried to build up on that myself. Other than that, I've been trying to learn web-dev, made a browser based game and tried to learn some back end. But I don't know exactly how to build up my proficiency with code, and solving problems, from here on out. So I would really appreciate if this golden community could help me out.(Not trying to flatter anyone. I don't express much, but all this is what I genuinely feel, and am grateful about.) I want to know how to go on about learning knew things in the realm of programming, and how I can apply it to solve actual problems. What language should I learn first? What will be valuable in this rapid-paced time? And some courses to help out?

I stumbled upon devRant one day out of nowhere, and I'm glad I did.

I dunno if you gents remember the Nickelodeon show known as Drake and Josh.

It was pretty big in Mexico and the U.S.

Well, one of the characters from that show is the singer/actor Drake Bell.

For a while, Drake Bell would **constantly** tweet about how much Justin Bieber sucks.

I aint denying that Justin Bieber sucks, i don't like his music at all.

But the constant attacks came out as jealousy, at least to me.

What does this has to do with development or even computers? Well this is EXACTLY how I feel about Louis Rossman CONSTANTLY making videos about apple products.
We get it man we really do, sadly for a lot of us the only way to get ios development done is through a fucking Mac

EVEN if his whiny ass is right about the hardware not being top notch and all that shit I AM still not able to explain a 2013(early...as in january) macbook pro still working with literally NO fucking problems. Before that the other macbook was just changed because we wanted the 2013 model. The thing worked, the one before did so too and the 2017 model that I have works, amazingly so i will add.

Still, the army of dell,hp and lenovo laptops that I've had before just died or are not functioning properly. Either it is my shit luck or Apple's "shitty hardware" got something really fucking right.

I think its retarded really. If you don't like them then fine, you don't have to, personally I fucking love all computers and os, but I don't get fanboys hating for the sake of hate.

the fuck you care if I spend 2500 on a computer? I would the same shit for your mom and the computer would last me longer.

Does owning multiple macs make me better than you? No

Does this mean that you are piss poor and can't afford shit and that is why you are hating? No

Will I call you <insert number of insults> gor your choice of pc or os? No

What is retarded is this: you all are DEVELOPERS(at least a good chunk) and your ass better fucking know that some people USE a certain tool because IT IS THE RIGHT ONE FOR THE JOB.

It is a damn fine operating system, a really good computing experience. It ain't your taste? Fine, das cool, but for fucks sake it does not mean that the other people are idiots or whatever.

Grow the fuck up and get yourself an opinion.

Sooooo... I've felt a bit lost during my years as a student and maybe this is a nice place to finally talk about it.
I've had my first programming experiences in school (back then it was delphi, a Pascal variant), then decided after graduating I want to study computer science. I've stuck with it and will finish my masters degree in a few months. (Took me a year longer than the university plans but will likely have a very good grade)

Since i have little programming experience and never coded anything useful (mostly study projects or simple programming tasks) I've always been struggling with depressions, worries of being not good enough and never finding a job etc pp, but in the last few months it got worse since I NEED to apply for jobs now as i graduate next may. I'd really like to improve and found some "learn how to code" websites but the progress seems still slow and meaningless when I compare myself to all those guys out there:
- those comparing several hardware/software pieces casually since they know all the (dis)advantages and specs off by heart
- those who have fierce discussions about languages, libraries, runtimes etc
- those who solve the problems in coding websites with 3 lines and incredibly mathematicsl proofs for why this shortcut works (fastest)
- basically the guys who discuss so many things i've never even heard of

I just feel so lost, useless and like i missed years of learning things everybody else just obviously knows now. Is there any way to catch up? I thought about trying to join a local Chaos Computer Club but they sound like they wouldn't be fond of a noob like me.

To me this is one of the most interesting topics. I always dream about creating the perfect programming class (not aimed at absolute beginners though, in the end there should be some usable software artifact), because I had to teach myself at least half of the skills I need everyday.

The goal of the class, which has at least to be a semester long, is to be able to create industry-ready software projects with a distributed architecture (i.e. client-server).

The important thing is to have a central theme over the whole class. Which means you should go through the software lifecycle at least once.

Let's say the class consists of 10 Units à ~3 hours (with breaks ofc) and takes place once a week, because that is the absolute minimum time to enable the students to do their homework.

1. Project setup, explanation of the whole toolchain. Init repositories, create SSH keys for github/bitbucket, git crash course (provide a cheat sheet).
Create a hello world web app with $framework. Run the web server, let the students poke around with it. Let them push their projects to their repositories.
The remainder of the lesson is for Q&A, technical problems and so on.

Homework: Read the docs of $framework. Do some commits, just alter the HTML & CSS a bit, give them your personal touch.
For the homework, provide a $chat channel/forum/mailing list or whatever for questions where not only the the teacher should help, but also the students help each other.

2. Setup of CI/Build automation. This is one of the hardest parts for the teacher/uni because the university must provide the necessary hardware for it, which costs money. But the students faces when they see that a push to master automatically triggers a build and deploys it to the right place where they can reach it from the web is priceless.
This is one recurring point over the whole course, as there will be more software artifacts beside the web app, which need to be added to the build process. I do not want to go deeper here, whether you use Jenkins, or Travis or whatev and Ansible or Puppet or whatev for automation. You probably have some docker container set up for this, because this is a very tedious task for initial setup, probably way out of proportion. But in the end there needs to be a running web service for every student which they can reach over a personal URL. Depending on the students interest on the topic it may be also better to setup this already before the first class starts and only introduce them to all the concepts in a theory block and do some more coding in the second half.

Homework: Use $framework to extend your web app. Make it a bit more user interactive with buttons, forms or the like. As we still have no backend here, you can output to alert or something.

3. Create a minimal backend with $backendFramework. Only to have something which speaks with the frontend so you can create API calls going back and forth. Also create a DB, relational or not. Discuss DB schema/model and answer student questions.

Homework: Create a form which gets transformed into JSON and sent to the backend, backend stores the user information in the DB and should also provide a query to view the entry.

4. Introduce mobile apps. As it would probably too much to introduce them both to iOS and Android, something like React Native (or whatever the most popular platform-agnostic framework is then) may come in handy. Do the same as with the minimal web app and add the build artifacts to CI. Also talk about getting software to the app/play store (a common question) and signing apps.

Homework: Use the view API call from the backend to show the data on the mobile. Play around with the mobile project to display it in a nice way.

5. Introduction to refactoring (yes, really), if we are really talking about JS here, mention things like typescript, flow, elm, reason and everything with types which compiles to JS. Types make it so much easier to refactor growing codebases and imho everybody should use it.
Flowtype would make it probably easier to get gradually introduced in the already existing codebase (and it plays nice with react native) but I want to be abstract here, so that is just a suggestion (and 100% typed languages such as ELM or Reason have so much nicer errors).
Also discuss other helpful tools like linters, formatters.

Homework: Introduce types to all your API calls and some important functions.

6. Introduction to (unit) tests. Similar as above.
Homework: Write a unit test for your form.

(TBC)

Today, I have installed/uninstalled a combination of [windows 7, arch linux, dual-boot] a total of 9 times...

I wouldn't be surprised if my 120G SSD fails next week

It all started when I had to whip up a GUI-wrapped youtube-dl based program for a windows machine.

Thinking a handy GUI python library will get it done in no time, I started right away with the Kivy quick-start page in front of me.

Everything seemed to be going fine, until I decided it would be "wise" to first check if I can run Kivy on said windows machine.

Here I spent what felt like a day (5 hours) trying to install core pip modules for kivy.. only before realizing my innocent cygwin64 setup was the reason everything was failing, and that sys.platform was NOT set to "win32" (a requirement later discovered when unpacking .whl files)

"Okay.. you know what? Fuck........ This."
In a haze of frustration, I decided it was my fault for ever deciding to do Python on windows, and that "none of this would've happened if I were installing pip modules on a Linux terminal"...

I then had the "brilliant" idea of "Why don't I just use Linux, and make windows a virtual machine within, for testing."

And so I spent the next hour getting everything set up correctly for me get back to programming.... And so I did.

But uh... you're doing GUI stuff, right? -> Yeah...

And you uh.. Kivy uses OpenGL on windows, doesn't it? -> Yeah..?

OpenGL... 2.

-> Fuck.

That's when I realized my "brilliant" idea, was actually a really bad prank. Turns out.. I needed a native windows environment with up-to-date non-virtual graphics drivers that supported at least OpenGL2 for Kivy GUI programs!

Something I already had from square 1.

And at this point, it hurts to even sigh knowing I wasted hours just... making... poor decisions, my very first one being cygwin64 as a substitution for windows cmd.

But persistent as any programmer should be in order to succeed, I dragged my sorry ass back to the computer to reinstall windows on the actual hardware... again.

While the windows installer was busy jacking off all over my precious gigabytes (why does it need that much spaaace for a base install??? fuck.). I had "yet another brilliant idea" YABI™

Why not just do a dual-boot? That way, you have the best of both worlds, you do python stuff in Linux, and when it's time to build and test on the target OS, you have a native windows environment!

This synthetic harmony sounded amazing to the desperate, exhausted, shell of a man that I had become after such a back-breaking experience with cygwin

Now that my windows platter with a side of linux was all set-up and ready-to-go, I once again booted up windows to test if Kivy even worked.

And... It did!

And just as I began raising my victory flags, I suddenly realized there was one more thing I had to do, something trivial, should take me "no time" to do, being in a native windows environment and all.................... -.- (sigh)

I had to make sure it compiles to a traditional exe...

Not a biggy, right? Just find one of those py2exe—sounding modules or something, and surprisingly enough, there was indeed a py2exe—sounding module, conveniently named... py2exe.

Not a second thought given, I thought surely this was a good enough way of doing it, just gonna look up the py2exe guide and...

-> 3 hours later + 1 extra coffee

What do you meeeeean "module not found"? Do I need to install more dependencies? Why doesn't it say so in the DAMN guide? Wait I don't? Why are you showing me that error message then????

-------------------------------

No. I'm not doing this.
I shut off my computer and took a long... long.. break.

Only to return sometime the next day and end up making no progress, beating my SSD with more OS installs (sometimes with no obvious reason to do so).

Wondering whether I should give up Kivy itself as it didn't seem compatible with py2exe.. I discovered pyInstaller, which seemed to be the way Kivy wants exe's to be made on windows..

Awesome! I should've looked up how Kivy developers make exe's instead of jumping straight into py2exe land, (I guess "py2exe" just sounded more effective to me then)

More hours pass, and you'd think I'd have eliminated all of my build environment problems by now... but oh, how wrong you'd be...

pyInstaller was failing, and half the solutions I found online were to download some windows update KB32946..whatever...

The other half telling me to downgrade from Python 3.8.1 to Python 3.8.0000.009 (exaggeration! But you get the point)

At the end of all that mess, I decided it wasn't worth some of my lifespan, and that maybe.. just maybe.. it would've been better to create WINDOWS GUI with the mother fuc*ing WINDOWS API.

Alright, step 1: Get Visual Studio..
Step 2: kys
Step 3: kys again.

Part of the problem, So many dev's here know the real problem with OS's governments and 3ed party apps happly spying on you and making there EULA to so called make it right for them to do it.

I want to know why so many dev's are portending this is not happen or why they not caring, you become part of the problem if your willing to work with the problem and there rules and guide lines.

WE dictate the future of tech not one company or another the people that create the software are the ones can make a difference, the users need to be educated and the dev need to take action now.

I loved this site at first but now I hate it I really do as so many posts are just blind or follow evil companies/software so on this is not how it should be, I wont accept this bull shit anymore and I not going to say quite to show the mass I going to follow them.

Step up and do something about it or stop calling yourself's dev's your part of the problem, you have the a gift and know how to help everyone do it and prove your worth.

I am really sorry I know some here do research and try and help but I rarely seeing it at the moment, things need to change, its not going to be easy but only the dev's can change this and soon, soon all OS's/software companies will get the feeling governments are on there side and governments what this so they have a back door in to WHO you are. FK the or if you have nothing to hide, EVERYONE has something to hide, compaines have already used Facebook Data to fire people working for them as they feel they shouldn't have to have someone working for them who likes or does XYZ,

Open your eyes people, small time dev's are not really included in this but big time dev's that do know how to work around these problems should be working on this to stop these problems, hardware venders are also a big problem but that's not something we can do anything about yet.

I know this rant will go on death ears to some, others will think I am over the top nut but if you really want to make a differences let's here it, lets get this world back on track, its not going to be easy but it we can do it.

Trying to run our Angular application today, got this error message: "Node Sass does not yet support your vurrent environment: OS X-64bit with Unsupported runtime (64)"
JavaScript frameworks cause problems on different hardware architectures and platforms. That probably was not easy to break...

Acer vs MSI Laptops.

Five years ago I bought an acer aspire vn7-591 laptop in Redcoon. It was the expensive laptop I bought ever in those days. My experience at the beginning was really bad because the battery laptop crashed after few months and the screen had some vague/dead pixels, but the worst was the imminent bankruptcy of Redcoon. So I couldn't use the warranty. Anyway, It didn't bother so much I have been enjoying this laptop and still doing it. However, last year the screen put me on alert since it started to fail with vertical bars and color changes.
It was time to buy a new computer and due to the problems with some of the components, I've decided to buy a laptop from a company with a better reputation than Acer in aspects as the reliability of the components.
My choice was a Msi Prestige 15 because of the thunderbolts, since the rest of specs are 'more or less similar', although it has more updated hardware, it is lighter, battery holds up to 4-5 hours etc... But... It is really noisy compared to my Acer computer. 2 CPU fans are around 3000 rpm in idle state... Acer seems to be working without using the fans if you are doing intensive work. I google it as I thought it was a factory problem, but it seems to be not a malfunctioning... In fact I found other users complaining about the same and the community proposed to reduce the fan speed through software.
Right now I have both laptops working and since the new boy is in house, Acer is working flawlessly. I am preparing the Acer for my girlfriend as a gift, otherwise it is a pitty to shut it down and store it in a wardrobe.
So, this is my impression about ACER and MSI. I m still experiencing with the new laptop, but I find weird things like the fan speed or how hot it gets in idle despite it uses a new generation of intel i7 cpu with lower consumption... I should monitor the power consumption...

Can anyone help me with this theory about microprocessor, cpu and computers in general?

( I used to love programming when during school days when it was just basic searching/sorting and oop. Even in college , when it advanced to language details , compilers and data structures, i was fine. But subjects like coa and microprocessors, which kind of explains the working of hardware behind the brain that is a computer is so difficult to understand for me 😭😭😭)

How a computer works? All i knew was that when a bulb gets connected to a battery via wires, some metal inside it starts glowing and we see light. No magics involved till now.

Then came the von Neumann architecture which says a computer consists of 4 things : i/o devices, system bus ,memory and cpu. I/0 and memory interact with system bus, which is controlled by cpu . Thus cpu controls everything and that's how computer works.

Wait, what?
Let's take an easy example of calc. i pressed 1+2= on keyboard, it showed me '1+2=' and then '3'. How the hell that hapenned ?

Then some video told me this : every key in your keyboard is connected to a multiplexer which gives a special "code" to the processer regarding the key press.
The "control unit" of cpu commands the ram to store every character until '=' is pressed (which is a kind of interrupt telling the cpu to start processing) . RAM is simply a bunch of storage circuits (which can store some 1s) along with another bunch of circuits which can retrieve these data.

Up till now, the control unit knows that memory has (for eg):
Value 1 stored as 0001 at some address 34A
Value + stored as 11001101 at some address 34B
Value 2 stored as 0010 at some Address 23B

On recieving code for '=' press, the "control unit" commands the "alu" unit of cpu to fectch data from memory , understand it and calculate the result(i e the "fetch, decode and execute" cycle)

Alu fetches the "codes" from the memory, which translates to ADD 34A,23B i.e add the data stored at addresses 34a , 23b. The alu retrieves values present at given addresses, passes them through its adder circuit and puts the result at some new address 21H.

The control unit then fetches this result from new address and via, system busses, sends this new value to display's memory loaded at some memory port 4044.
The display picks it up and instantly shows it.

My problems:
1. Is this all correct? Does this only happens?

2. Please expand this more.
How is this system bus, alu, cpu , working?
What are the registers, accumulators , flip flops in the memory?
What are the machine cycles?
What are instructions cycles , opcodes, instruction codes ?
Where does assembly language comes in?
How does cpu manipulates memory?
This data bus , control bus, what are they?
I have come across so many weird words i dont understand dma, interrupts , memory mapped i/o devices, etc. Somebody please explain.

Ps : am learning about the fucking 8085 microprocessor in class and i can't even relate to basic computer architecture. I had flunked the coa paper which i now realise why, coz its so confusing. :'''(

My 2 cents on different OSes to use.

I think Linux is best for running servers and services and having long run times with little issues (when its Console and not GUI based.) But I have a lot of issues with using its GUI distributions like Ubuntu and it feels kind of unpolished in that area.

I prefer macOS for its GUI as it actually works and has far less issues than Windows GUI and is (IMO) better than Linux GUI's by far. But macOS just doesn't feel like it was designed super users and it can feel like its holding you back a bit. Also you have to use Mac hardware which are amazing machines, they are just overpriced.

I prefer Windows for its GUI and despite its problems, it is very well designed for super users and has very well designed remote desktop features and scalability (although it is a pain to maintain.) Windows works well for connected company systems.

In my opion:
Linux: Servers, databases (no GUI)

macOS: Designers, photo/video editing, IT/programmers and general use as a standalone (not part of a company system).

Windows: IT/programmers, super users, general use but better than macOS at working together in a company setup, but macOS is better at being a personal laptop or PC.

I personally use Linux for our email and web servers. Windows for our company computers (designers use Macs) and I have a Macbook as my own personal computer.

Thanks google for creating the illusion of an option to change the shipping address for a repair order. You even mention the new address in your notification email, but when I click on UPS tracking, I can see that you sent the shipment to the old address, which is in a different city where I can't quickly go to pick up my repaired phone. After charging an extra 95,- Euros for additional damage supposedly not covered by my warranty. Lucky you that my old phone had connection problems with the shitty Vodafone station wi-fi router, which is one of the few reasons that I still even want to use a google hardware product. Thanks google for just being slightly less wretched and mediocre than your competitors, that might grant you some more years before you will be buried in history forever. Pixel phones are just like Macbooks: high quality product and good marketing, good enough to make your customer accept everything else being bullshit. Google search is even worse, but based on the same concept: just suck a little less than your competitors but don't waste any effort trying to actually be really good at anything.

(I'm not completely sure of what I'm saying here, so don't take this too seriously)

Settling on a language to write the api for ranterix is hard.

I'm finding a lot of things about elixir to be insanely good for a stable api.

But I'm having a lot of gripes with the most important elixir web framework, phoenix.

Take a look at this piece of code from the phoenix docs:

defmodule Hello.Repo.Migrations.CreateUsers do
use Ecto.Migration
def change do
create table(:users) do
add :name, :string
add :email, :string add :bio, :string
add :number_of_pets, :integer
timestamps()
end
end
end

Jesus christ, I hate this shit.

Wtf are create, add and timestamps. Add is somehow valid inside the create, how the fuck is that considered good code? What happens if you call timestamps twice? It's all obscure "trust me, it works" code.

It appears to be written by a child.

js may have a million problems. But one thing I like about CJS (require) or ESM (import) is that there's nothing unexplained. You know where the fuck most things come from.

You default export an eatShit() function on one file and import it from another, and what do you get?
The goddamn actual eatShit function.

require is a function the same way toString is a function and it returns whatever the fuck you had exported in the target file.

Meanwhile some dynamic langs are like "oh, I'll just export only some lang construct that i expect you to specify and put that shit in fucking global of the importing file".

Js is about the fucking freedom. It won't decide for you what things will files export, you can export whatever the fuck you want, strings, functions, classes, objects or even nothing at all, thanks to module.exports object or export statement.

And in js, you can spy on anything external, for example with (...args) => debugger; fnToSpyOn(...args)

You can spoof console.log this way to see what the fuck is calling it (note: monkey patching for debugging = GOOD, for actual programming = DOGSHIT)

To be fair though, that is possible because of being a dynamic lang and elixir is kind of a hybrid typed lang, fair enough.

But here's where i drop the shit.

Phoenix takes it one step further by following the braindead ruby style of code and pretty DSLs.

I fucking hate DSLs, I fucking hate abstraction addiction.

Get this, we're not writing fucking poetry here. We're writing programs for machines for them to execute.

Machines are not humans with emotions or creativity, nor feel.

We need some level of abstraction to save time understanding source code, sure.

But there has to be a balance. Languages can be ergonomic for humans, but they also need to be ergonomic for algorithms and machines.

Some of the people that write "beautiful" "zen" code are the folks that think that everyone who doesn't push the pretty code agenda is a code elitist that doesn't want "normal" people to get into programming.

Programming is hard, man, there's no fucking way around it.

Sometimes operating system or even hardware details bleed into code.

DSLs are one easy way to make code really really easy to understand, but also make it really fucking hard to debug or to lose "programming meaning".

I fucking hate Windows... Yes I know it's beating a dead horse, but bear with me for a second here:

I really didnt mind it before, but I fucked up majorly on my dual-booted PC yesterday (dont fuck around with systemd if you don't know what you're doing) and needed to reinstall both Linux and Windows. Linux still has some hardware problems (second screen's not being detected), but else everything's just dandy.
But Windows... Holy motherfucking horse-cum drenched piece of goddamn trash! Shit wont listen to me!! I can click in that retarded settings app whatever I want and it still merrily keeps doing whatever the hell it wants 🙄🙄 Why exactly do I still put up with that?!

(It's gaming)

Working code?
Or fake compiler?
Fix a problem?
Or buy a new computer?
Bring a flash drive?
Or bring a hard drive?
Use water cooling?
Or use an ice cube on top a processor and memory?
Drink some coffee?
Or eat a healthy breakfast?
Do you make hardware?
Or software?
These are the problems programmers face from old people as employers or relatives trying to find something to relate to.

So I've been using Duet on my iPad Pro for a couple years now (lets me use it as an external monitor via Lightning cable) and without issue. Shit, I've been quite happy with it. Then the other day, whilst hooked up to my work laptop, there was a power fluctuation that caused my laptop to stop sending power to connected devices. Which is fine - I have it plugged into a surge protector so these fluctuations shouldn't matter. After a few seconds the laptop resumed normal operation and my connected devices were up and running again.

But the iPad Pro, for some reason, went into an infinite boot loop sequence. It reboots, gets to the white Apple logo, then reboots again.

In the end, after putting the iPad into recovery mode and running Apple's update in iTunes (as they recommend), it proceeds to wipe all my data. Without warning. I lost more than a couple of years of notes, illustrations and photos. All in one fucking swoop.

To be clear, you get 2 options in iTunes when performing a device update:

1. UPDATE - will not mess with your data, will just update the OS (in this case iPadOS)
2. RESTORE - will delete everything, basically a factory reset

I clicked UPDATE. After the first attempt, it still kept bootlooping. So I did it again, I made sure I clicked UPDATE because I had not yet backed up my data. It then proceeds to do a RESTORE even though I clicked UPDATE.

Why, Apple? WHY.

After a solemn weekend lamenting my lost data, I've come a conclusion: fuck you Apple for designing very shitty software. I mean, why can't I access my device data over a cabled connection in the event I can't boot into the OS? If you need some form of authentication to keep out thieves, surely the mutltiple times you ask me to log in with my Apple ID on iTunes upon connecting the damn thing is more than sufficient?! You keep spouting that you have a secure boot chain and shit, surely it can verify a legitimate user using authenticated hardware without having to boot into the device OS?

And on the subject of backing up my data, you really only have 2 manual options here. Either (a) open iTunes, select your device, select the installed app, then selectively download the files onto my system; or (b) do a full device backup. Neither of those procedures is time-efficient nor straightforward. And if you want to do option b wirelessly, it can only be on iCloud. Which is bullshit. And you can't even access the files in the device backup - you can only get to them by restoring to your device. Even MORE bullshit.

Conversely, on my Android phone I can automate backups of individual apps, directories or files to my cloud provider of choice, or even to an external microSD card. I can schedule when the backups happen. I can access my files ANYTIME.

I got the iPad Pro because I wanted the best drawing experience, and Apple Pencil at the time was really the best you could get. But I see now it's not worth compromise of having shitty software. I mean, It's already 2021 but these dated piles of excrement that are iOS and iPadOS still act like it's 2011; they need to be seriously reviewed and re-engineered, because eventually they're going to end up as nothing but all UI fluff to hide these extremely glaring problems.

I don't understand those rants about problems that can be fixed by just googling some keywords..or even the slightly harder ones where you could just tinker with the device for a bit and get closer to a solution/workaround... i mean if it's not a hardware problem then it can clearly have a solution.
my reasons:
1- you use your knowledge for good
2- you learn something new
3- you don't let the tech guys get bothered by small tedious problems

!long_rant
So, my previous rant was one of the most liked rant for me so far, in which I simply stated I am moving to Ubuntu.
I feel ashamed to say that I am moving back to Windows(for now at least).
The reason is not Ubuntu, I actually found it lovely. Its my friggin laptop. While there are many other problems, but the biggest is that the wifi adapter's range has fallen drastically in linux. On Windows it was working fine, I also checked Kali and tails(live) and both show the same issue. My router was literally 3 meters away and this shitty laptop couldn't connect. Since, it connects on Windows properly, its obviously a driver problem, the shitty creators haven't released an API for linux devs. Now, I have tried a lot of suggestions from SO but if I can't find a solution I will either have to arrange another laptop or simply go back to that always updating OS. There is another problem, the graphics card is not even being recognized. No idea how shitty hardare this laptop has.
Btw its an HP ac110tx.
Tell you what, I recently bought it from Paytm and thought its an i7 5gen processor with a graphics card for a reasonable price, what can go wrong. This is the issue. Hardware was shitty. I hate this laptop. If I had the money I wouldn't think twice before dumping this laptop on ebay/quickr. But, we are struggling devs(at least I am), don't have a big amount coming soon.
Very depressed and angry!

Any gift recommendations. My birthday comes up in a few days and he asked what I wanted as a birthday gift(gifts are supposed to suprises but being able to choose is good still).

However I cannot ask for electronic gadgets. That knocks a lot of stuff of. The exception is that if something does not make me spend more time on the computer that is allowed. Kinda weird. For example I can ask for a printer or medical equipment like oximeters since that wont make me spend more time on the computer. Both of these examples were given by my father. I could ask for a new printer however we still have a printer but it is currently in the shop since it is not being used and the shops printer broke and is hell to replace since they need chips to verify toners and you need to get those chips separately from what my father told me and the shops printer should be repaired in a few months since lockdown was lifted a few days ago and I won't need to print something since everything is online and they don't need to show student projects yet.

Thia knocks a lot of hardware off since by definition if I am using hardware I still need to code it to do something which is more time on computer which is not allowed. So no fiddling with aurdino or rasberry pie or whatever is the most used hardware kit.

I can buy some course or a book to learn something but I already have problems with consistently learning c# with a good book which will lose value in November and that most topics I would like to learn like computer networking or some new language are practical which is more time on computer which is not allowed.

So the only thing I can buy are some books to enjoy reading for fun or some school books like a science digest book like Together with or the ultra popular maths reference book RD Sharma

So what things should I ask which comply with the rules my father has laid or just skip this thing
