Its Friday, you all know what that means! ... Its results day for practiseSafeHex's most incompetent co-worker!!!
*audience: wwwwwwooooooooo!!!!*
We've had a bewildering array of candidates, lets remind ourselves:
- a psychopath that genuinely scared me a little
- a CEO I would take pleasure seeing in pain
- a pothead who mistook me for his drug dealer
- an unbelievable idiot
- an arrogant idiot obsessed with strings
Tough competition, but there can be only one ... *drum roll* ... the winner is ... none of them!
*audience: GASP!*
*audience member: what?*
*audience member: no way!*
*audience member: your fucking kidding me!*
Sir calm down! this is a day time show, no need for that ... let me explain, there is a winner ... but we've kept him till last and for a good reason
*audience: ooooohhhhh*
You see our final contestant and ultimate winner of this series is our good old friend "C", taking the letters of each of our previous contestants, that spells TRAGIC which is the only word to explain C.
*audience: laughs*
Oh I assure you its no laughing matter. C was with us for 6 whole months ... 6 excruciatingly painful months.
Backstory:
We needed someone with frontend, backend and experience with IoT devices, or raspberry PI's. We didn't think we'd get it all, but in walked an interviewee with web development experience, a tiny bit of Angular and his masters project was building a robot device that would change LED's depending on your facial expressions. PERFECT!!!
... oh to have a time machine
Working with C:
- He never actually did the tutorials I first set him on for Node.js and Angular 2+ because they were "too boring". I didn't find this out until some time later.
- The first project I had him work on was a small dashboard and backend, but he decided to use Angular 1 and a different database than what we were using because "for me, these are easier".
- He called that project done without testing / deploying it in the cloud, despite that being part of the ticket, because he didn't know how. Rather than tell or ask anyone ... he just didn't do it and moved on.
- As part of his first tech review I had to explain to him why he should be using if / else, rather than just if's.
- Despite his past experience building server applications and dashboards (4 years!), he never heard of a websocket, and it took a considerable amount of time to explain.
- When he used a node module to open a server socket, he sat staring at me like a deer caught in headlights completely unaware of how to use / test it was working. I again had to explain it and ultimately test it for him with a command line client.
- He didn't understand the need to leave logging inside an application to report errors. Because he used to ... I shit you not ... drive to his customers, plug into their server and debug their application using a debugger.
... props for using a debugger, but fuck me.
- Once, after an entire 2 days of tapping me on the shoulder every 15 mins for questions / issues, I had to stop and ask:
Me: "Have you googled it?"
C: "... eh, no"
Me: "can I ask why?"
C: "well, for me, I only google for something I don't know"
Me: "... well do you know what this error message means?"
C: "ah good point, i'll try this time"
... maybe he was A's stoner buddy?
- He burned through our free cloud usage allowance for a month, after 1 day, meaning he couldn't test anything else under his account. He left an application running, broadcasting a lot of data. Turns out the on / off button on the dashboard only worked for "on". He had been killing his terminal locally and didn't know how to "ctrl + c a cloud app" ... so left it running. His intention was to restart the app every time you are done using it ... but forgot.
- His issue with the previous one ... not any of his countless mistakes, not the lack of even trying to make the button work, no, no, not for C. C's issue is the cloud is "shit" for giving us such little allowances. (for the record in a month I had never used more than 5%).
- I had to explain environment variables and why they are necessary for passwords and tokens etc. He didn't know it wasn't ok to commit these into GitHub.
- At his project meetups with partners I had to repeatedly ask him to stop googling gifs and pay attention to the talks.
- He complained that we don't have 3 hour lunch breaks like his last place.
- He once copied and pasted the same function 450 times into a file as a load test ... are loops too mainstream nowadays?
You see C is our winner, because after 6 painful months (companies internal process / requirements) he actually achieved nothing. I really mean that, nothing. Every thing was so broken, so insecure / wide open, built without any kind of common sense or standards I had to delete it all and start again ... it took me 2 weeks.
I hope you've all enjoyed this series and will join me in praying for the return of my sanity ... I do miss it a lot.
Yours truly,

Hello everyone, found this place recently, decided to bore you with one (or many) Navy story... tech Navy story. I'll start from the end.
Little backstory: I've deployed a simple domain setup on the ship I served, nothing fancy, a server, a switch, 10 computers, all Windows (details on that at another rant). I enter the ship Monday morning, and the XO tells me that he can't access his online folders.
OK, I say, I'll get to it. I fire up my laptop, try to RDP to the server (I know, I know, burn me at the stake later) no connection. WTF? Is the service down? I try pinging. No luck. I tried pinging the switch. OK. Looking at the switch admin panel, I see the server's port is dead. "OK, probably the cable." (we have old ethernet cables)
So, I drag my ass over to the server (same room with ship comms) with the cable tester to confirm that. What do I see?
The IMBECILES had pulled the plug from the server so that they could charge their mobile phones. I literally slammed my head against the door (calming exercise in case of spontaneous murder impulses - the things you learn at the Academy). My CO was nearby, and lucky for the guys, he heard me yell at them, while throwing mobiles and chargers around.
"But we thought it was OK, we just wanted to charge our-"
I kid you not, I reached for the firefighter's axe.
My CO grabbed me by the collar and dragged me to his room. I explained to him (between two cigarettes) that we MUST get a UPS and a server cabinet (budget constraints in the military are something that will give you people nightmares, trust me). I carefully explained to him that unless we got those, nothing would prevent the next moron from destroying confidential data and me from murdering him.
I plugged in and booted the server, after installing a multi socket extension. Two days after, surprise surprise, the server was off again. That was the first time I opened the door to the CO's room with a low kick. I must have looked like a psycho on drugs, he gave approval for the purchase in twenty seconds flat.
After that, I installed the UPS and the cabinet. Everything went inside, from the UPS to the very plugs. Just a locked box with cables coming out.
One of the guys came to my room, and asked if I could unlock the cabinet so that they could plug a "device" they needed.
I actually reached for my folding knife.
Disclaimer: The story above is TRUE. Even the almost violent parts.23 -
My friend: OMG OMG OMG My laptop is dead!
Me: What do you mean it's dead? It doesn't even turn on?
My friend: Nooo, it does nothing?
Me: Are you sure it's plugged in?
My friend: Yesss
Me: You sure?
My friend: Yess, it's actually plugged into a multiple socket thingy...
Me: And that thing is plugged in to the wall..?
My friend: Well duh!
Me: And did you turn the switch on?
My friend: Of course I....oh, wait!! Never mind!!!!!
Me: >:/5 -
It finally hit me the other day.
I'm working on an IoT project for a late-stage ALS patient. The setup is that he has a tablet he controls with his eye movements, and he wants to be able to control furnishings in his room without relying on anyone else.
I set up a socket connection between his tablet and the Raspberry Pi. From there it was a simple matter of using GPIO to turn a lamp or fan on or off. I did the whole thing in C, even the socket programming on the Pi.
As I was finishing up the main control of the program on the Pi I realized that I need to be more certain of this than anything I've ever done before.
If something breaks, the client may be forced to go days without being able to turn his room light on, or his fan off.
Understand he is totally trapped in his own body so it's not like he can simply turn the fan off. The nursing staff are not particularly helpful and his wife is tied up a lot with work and their two small children so she can't spend all day every day doting on him.
Think of how annoying it is when you're trying to sleep and someone turns the light on in your room; now imagine you can't turn it off yourself, and it would take you about twenty minutes to tell someone to turn it off -- that is once you get their attention, again without being able to move any part of your body except your eyes.
As programmers and devs, it's a skill to do thorough testing and iron-out all the bugs. It is an entirely different experience when your client will be depending on what you're doing to drastically improve his quality of life, by being able to control his comfort level directly without relying on others -- that is, to do the simplest of tasks that we all take for granted.
Giving this man some independence back to his life is a huge honor; however, it carries the burden of knowing that I need to be damned confident in what I am doing, and that I have designed the system to recover from any catastrophe as quickly as possible.
In case you were wondering how I did it all: The Pi launches a wrapper for the socket connection on boot.
The wrapper launches the actual socket connection in a child process, then waits for it to exit. When the socket connection exits, the wrapper analyzes the cause for the exit.
If the socket connection exited safely -- by passing a special command from the tablet to the Pi -- then the wrapper exits the main function, which allows updating the Pi. If the socket connection exited unexpectedly, then the Pi reboots automatically -- which is the fastest way to return functionality and to safeguard against any resource leaks.
The socket program itself launches its own child process, which is an executable on the Pi. The data sent by the tablet is the name of the executable on the Pi. This allows a dynamic number of programs that can be controlled from the tablet, without having to reprogram the Pi, except for loding the executable onto it. If this child of the socket program fails, it will not disrupt its parent process, which is the socket program itself.13 -
A friend of mine is heavily into java. Like seriously... programming teachers at our school ask him for help.
Everytime he gets drunk he starts saying the weirdest things like "DUDE what's your alpha value I can hardly see you".
He greets me with "What's up socket boy" and after throwing up he thinks about the best ways to sort the data. (his vomit)
Has anyone else had such experiences? I want to hear some funny stories! :D12 -
/*
It's a pretty long rant. Hope you didn't get bored :P
*/
So I have this friend of mine who has learnt Python at good level (that's what he says) and is with me in all classes in college. I have worked with C, C++, C# and Java only and hated Python when it was taught (wk44).
So the following happened in the last 2 weeks:
Once he wrote a Python function in terminal just returning a hard coded string (lame right) and will show me how cool is it and that it is sooo much easier.
Whenever we do a mini project together he will force that we use Python. Even in Image processing when everyone is ready to work on Matlab, he insists that Python would be a better option.
We asked that this XYZ is very easy to implement on Matlab.
We then had to listen about the large and great community of Python and that it has Libraries for everything and that it is the greatest programming language ever.
One day he saw my C# project for DFA and NFA simulation which was the greatest project I have "completed" myself, and went like "Hmph, if I was you, I would use python and make a more "professional" code" (then went on arguing as always)
This happened today in Networking lab-
(Sockets was taught and we are expected to learn its programming aspects)
All students: Open linuxhowtos.org and start reading on socket programming
He : Opens some websites and downloads books on Networking with Python or someting
Now while I am reading the documentation of sockets and bind, he opens spider IDE, copy-paste the code in the book and start bugging ME that he is getting all these errors like literally showing me those errors and whining about all those problems.
Me: We are supposed to learn this in C. Here take a look at this link.
HE: No I'll use Python cuz it is better than your C. It has libraries for everything and is much easier.
Me: Alright whatever I am fed up, do whatever you want11 -
What my lecturer think I have learned:
- Programming Patterns
- C, C++, Java
- Socket programming, web programming
- Operating system...
What I have actually learned:
1. printf("Hello World");
2. echo "Hello World";
3. console.log("Hello World");
4. Console.Writeline("Hello World");
5. cout << "Hello World" >> endl;
6. System.out.println("Hello World");
7. puts "Hello World";
8. "Hello World"
9. write("Hello World");
10. Display "Hello World"10 -
Last weekend I witnessed the most infected computer I have ever seen in my life...
I went on a private party. A girl had her laptop plugged to the speakers to play some music. This thing was literally 99% cancer. The first thing I noticed, when I looked at her opened browser, was that nearly half the screen was taken by toolbars. Also any popular website you could visit had additional ads INJECTED into it. The fist 10 YouTube search results: always porn. No idea how that didn't make her suspicious.
Precisely every 10th click (anywhere not only in the browser) would open up a window with either more ads or an aggressively blinking message saying: "A virus has been detected on your machine. Click here to download our antivirus programm. You have 60 seconds left before your firewall breaks!!!".
Also physically this device was on the edge of completely broken. The power supply had to be taped to the socket because it was so loose. Every little jiggle would immediatly shut the system down and Windows had to be completely reinstalled (which of course didn't solved any of the "software issues").
First I wanted to use that laptop to show some friends a new web project of mine but this thing probably would have DDoSed the shit out of my recently finished work or something.
I couldn't decide if I should laugh or cry...9 -
My first hack... Back at the days when phones had disks to dial a number. I was a kid of cause, I'm not that old. I used to like to call my grans. Once, when I supposed to go to sleep already, I've found out that there is phone socket in my room (the one connected to the copper wire, that is where the word "phone line" came from).
It took me about a half of an hour to detach handset from the toy phone and about two ours to reverse engineer dialing protocol (you just need to disconnect the line sequentially corresponding number if times).
And after that I've heard my granny's voice. I was literally overwhelmed that it worked.6 -
Since most of the pics here are either joke/memes or battlestations or laptop on a nice desk..... I give you my humble coding corner on my bed from a 3rd world country. Still student so....gotta improvise. No, desk is too far away for power socket.

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.3 -
Windows 10 is asking me if I want to put my 5-8kg desktop computer in flight mode.
I'm now picturing my self looking for a power socket needing 650w in a airplane3 -
Years ago we deployed this system with a SQL DB on a separate windows server.
Every now and then we had error messages saying that the system could not connect to the db. It was going on for about 5 minutes or so and then the db was up again.
We built a bunch of fallback logic to handle it gracefully.
Then one day one of the guys was in the "server room". It was not a real server room but like a dedicated office in another building.
He saw how the cleaning lady came in, unplugged the server's cable from the wall socket and plugged in the vacuum cleaner...6 -
If you are a salesperson, you can just go straight to hell. You're all a bunch of cocksucking twats and I'm amazed you manage to get yourselves dressed each day. You're a no good fucking waste of oxygen and you need to put your fork in a socket the next time you're eating.
I'm working on building a crm and ticket management system for use in the office to handle client passwords. Since I'm building from scratch I wanted to make sure I had properly planned my classes and functions before opening the code editor so I put a message on my door that says "Don't interrupt, thanks" followed by the date so people knew it was a fresh message and not something left from the previous day.
I'm deep in the zone, the psuedo code and logic is flowing, I'm getting classes planned and feeling really productive for an hour or so when suddenly my door flies open and in comes a sales person.
SP: "Hey, do you have any extra phones lying around? Mine's being slow and keeps hanging up on people."
Me: "Do you see the sign on my door right there at eye level which says not to bother me?"
SP: "oh, do you want me to come back later?"
Me: "You've already interrupted me now, let's go see what's going on before I spent an hour setting up a new phone for you." While we are walking across the office I asked him when the last time the phone rebooted.
SP: "idk, Salesperson#2 suggested that as I was headed over here but I figured I'd just ask you."
We get over to his desk and I see he has two phones sitting on his desk. "Where did this one come from?"
SP: "Oh that was on the desk over here but I figured I could use it."
Me: "Well aside from the fact that the phones are assigned to specific people for a reason, you took the time to unhook your phone to set this one up and you didn't think to reboot your phone first. Plug your phone back in."
He plugs the old phone, which is assigned to him, and while booting it does a quick firmware update and boots up fine. He tests a few things and decides it's all better now.
So someone suggested a fix for you and you decided, instead, you would break company IT policy by moving equipment from one station to another without notifying the IT department. You entered a room which had a closed door without knocking, and you disobeyed the sign on the actual door itself which politely requests that you go away. All because you couldn't be bothered to take 2 minutes and reboot your phone, which you had to do anyways.
You completely broke my train of thought and managed to waste 2 hours of effecient workflow because you had an emergency.9 -
Forgive me father, for I have sinned. Alot actually, but I'm here for technical sins. Okay, a particular series of technical sins. Sit your ass back down padre, you signed up for this shit. Where was I? Right, it has been 11429 days since my last confession. May this serve as equal parts rant, confession, and record for the poor SOB who comes after me.
Ended up in a job where everything was done manually or controlled by rickety Access "apps". Many manhours were wasted on sitting and waiting for the main system to spit out a query download so it could be parsed by hand or loaded into one of the aforementioned apps that had a nasty habit of locking up the aged hardware that we were allowed. Updates to the system were done through and awful utility that tended to cut out silently, fail loudly and randomly, or post data horrifically wrong.
Fuck that noise. Floated the idea of automating downloads and uploads to bossman. This is where I learned that the main system had no SQL socket by default, but the vendor managing the system could provide one for an obscene amount of money. There was no buy in from above, not worth the price.
Automated it anyway. Main system had a free form entry field, ostensibly for handwriting SELECT queries. Using Python, AutoHotkey, and glorified copy-pasting, it worked after a fashion. Showed the time saved by not having to do downloads manually. Got us the buy in we needed, bigwigs get negotiating with the vendor, told to start developing something based on some docs from the vendor. Keep the hacky solution running as team loves not having to waste time on downloads.
Found SQLi vulnerability in the above free form query system, brought it up to bossman to bring up the chain. Vulnerability still there months later. Test using it for automated updates. Works and is magnitudes more stable than update utility. Bring it up again and show the time we can save exploiting it. Decision made to use it while it exists, saves more time. Team happier, able to actual develop solutions uninterrupted now. Using Python, AutoHotkey, glorified copy-pasting, and SQLi in the course of day to day business critical work. Ugliest hacky thing I've ever caused to exist.
Flash forward 6 years. Automation system now in heavy use acrossed two companies. Handles all automatic downloads for several departments, 1 million+ discrete updates daily with alot of room for expansion, stuff runs 24/7 on schedule, most former Access apps now gone and written sanely and managed by the automation system. Its on real hardware with real databases and security behind it.
It is still using AutoHotkey, copy-paste, and SQLi to interface with the main system. There never was and never will be a SQL socket. Keep this hellbeast I've spawned chugging along.
I've pointed out how many ways this can all go pearshaped. I've pointed out that one day the vendor will get their shit together they'll come in post system update and nothing will work anymore. I've pointed out the danger in continuing to use the system with such a glaring SQLi vulnerability.
Noone cares. Won't be my problem soon enough.
In no particular order:
Fuck management for not fighting for a good system interface
Fuck the vendor for A) not having a SQL socket and B) leaving the SQLi vulnerability there this long
Fuck me for bringing this thing into existence5 -
On a tiny vacation in another country. Don't have a converter plug (for the power sockets) so borrowed one.
*connects laptop to charger* (old charger which might die soon)
*nothing happens*
*slight panic*
*tries different sockets*
*nothing*
😨😲😭
"you might want to check your phone with that thing as the socket seems loose as hell"
*tries phone with charger that definitely works*
*nothing*

last night i was searching for a way to check the battery charge level of my bluetooth headset on linux. None of the workarounds seemed to work for me. I did some research on how bluetooth devices communicate over socket and wrote a python script to do the job. I'm sharing it here. It may be useful for you too.

Some of my friends and me stayed the night in a small house. Everyone except me drank beer and now they are all sleeping while I am sitting right next to the socket in a corner listening to music and reading through the documentation of java.

I have in my head parts of a game, I'd love to build. A top-down space colonization game. You control various spacecrafts and build spacestations etc. to expand your control.
The catch is that you have limited direct controls in-game. Most of the "gameplay" consists of having your own piece of software running somewhere, communicating with the API and controlling your colony.
Similar to Screeps, but I don't like the limitations of writing JavaScript and uploading it to the service. I'd love for the user to have free control of what language to use. They just need to be able to create a TCP socket and communicate with the API24 -
Number one thing I never expected, when moving networking equipment...

The IT head of my Client's company : You need to explain me what exactly you are doing in the backend and how the IOT devices are connected to the server. And the security protocol too.
Me : But it's already there in the design documents.
IT Head : I know, but I need more details as I need to give a presentation.
Me : (That's the point! You want me to be your teacher!) Okay. I will try.
IT Head : You have to.
Me : (Fuck you) Well, there are four separate servers - cache, db, socket and web. Each of the servers can be configured in a distributed way. You can put some load balancers and connect multiple servers of the same type to a particular load balancer. The database and cache servers need to replicated. The socket and http servers will subscribe to the cache server's updates. The IOT devices will be connected to the socket server via SSL and will publish the updates to a particular topic. The socket server will update the cache server and the http servers which are subscribed to that channel will receive the update notification. Then http server will forward the data to the web portals via web socket. The websockets will also work on SSL to provide security. The cache server also updates the database after a fixed interval.
This is how it works.
IT Head : Can you please give the presentation?
Me : (Fuck you asshole! Now die thinking about this architecture) Nope. I am really busy.11 -
Hi hackers!
Just not sure about this one:
Is this true?
The closer i get to the router , the more packets i might be able to sniff.
And something else:
I might loose the traffic sent to the other APs while i'm close to one another.
Is there any way to capter all packets?
(I also have wired access to network but since the socket isolates the traffic let me know if there is any other method)
Thanks16 -
Coolest thing I’ve built solo?
Damn, there’s been a lot of things over the years, but I guess the most used one I’ve made would be my voice activated tv remote - yes it’s real.
So in essence it’s a google home... yea I know spyware and all, but look it was free so I’m going to make use of it... err where was I, oh yea.
An IFTTT account which taps into the google assistant API and creates a webhook, although the authentication side of things is 0 to none, so had to put a api-key into the requests to at least have some layer of auth.
This webhook then hits a raspberry pi containing a PHP API to accept and authenticate the request in, digest this into KEY commands for the TV, and drops this into a Python script to connect to the TV over a web socket connection ( I found python more stable for this ) and sends the pre made key requests, it can even do multiple keys at a time... that was a pain.
So after all that, the end game becomes about a second from saying “hey google, change the tv channel to xxx”
This sick and twisted contraption is finished and the tv is my little bitch.
This has been built out to handle channels by name, number, volume up/down, sources switching to hdmi, tv, vga and a bunch of other things.
The things we do when we can’t find a tv remote for days....
Next up, getting it to launch Netflix app and going to a specified show / episode.. but may be to adventurous. -
Spent an hour trying to figure out what was wrong in my socket disconnect detection code because it was constantly reporting disconnects when it shouldn't have... Only to find it was a pinched cable causing the problem. Meaning it actually did work the entire time.1

iPhones are ridiculously picky when it comes to finding a mate- um charger. And knowing why doesn't really make it any easier to understand why. If anything it baffles me more.
So, let's start with appliances that are not phones. Think Bluetooth headsets, keyboards, earbuds, whatever. Those are simple devices. They see 5V on the VCC line and 0V on ground, and they will charge at whatever current they are meant to. Usually it will not exceed 200mA, and the USB 2.0 spec allows for up to 500mA from any USB outlet. So that's perfectly reasonable to be done without any fuss whatsoever.
Phones on the other hand are smarter.. some might say too smart for their own good. In this case I will only cover Android phones, because while they are smarter than they perhaps should be, they are still reasonable.
So if you connect an Android phone to the same 5V VCC and 0V ground, while leaving the data lines floating, the phone will charge at 500mA. This is exactly to be within USB 2.0 spec, as mentioned earlier. Without the data lines, the phone has no way to tell whether it *can* pull more, without *actually* trying to pull more (potentially frying a charger that's not rated for it). Now in an Android phone you can tell it to pull more, in a fairly straightforward way. You just short the data lines together, and the phone will recognize this as a simple charger that it can pull 1A from. Note that shorting data lines is not a bad thing, we do it all the time. It is just another term for making a connection between 2 points. Android does this right. Also note that shorted data lines cannot be used to send data. They are inherently pulled to the same voltage level, probably 0V but not sure.
And then the iPhones come in, Thinking Different. The iPhones require you to pull the data lines to some very specific voltage levels. And of course it's terribly documented because iSheep just trying to use their Apple original white nugget charger overseas and shit like that. I do not know which voltage levels they are (please let me know!), but it is certainly not a regular short. Now you connect the iPhone to, say, a laptop or something to charge. An Android phone would just charge while keeping data transmission disabled (because they can be left floating or shorted). This is for security reasons mostly, preventing e.g. a malicious computer from messing with it. An iPhone needs to be unlocked to just charge the damn thing. I'm fairly sure that that's because the data lines need to be pulled up, which could in theory enable a malicious computer to still get some information in or out of it. USB data transmission works at at least 200mV difference between the data lines. It could be more than that. So you need to unlock it.
Apple, how about you just short your goddamn data lines too like everyone else? And while you're at it, get rid of this Lightning connector. I get it, micro USB was too hard for your users. I guess they are blind pigs after all. But USB-C solved all of that and more. The only difference I can think of is that the Lightning connector can be a single board with pads on either side on the connector, while in USB-C that could be at the socket end (socket being less common to be replaced). And at the end of the day, that really doesn't matter with all the other things that will break first.
Think Different. Think Retarded. Such tiny batteries and you can't even fucking charge them properly.6 -

Been working for a while with some terrible code with no documentation that I just inherited from a previous employee
Topic: multi-threaded program in Python
Goal: kill both parent and children with keyboard interrupt
Intuitive idea: check in children processes if parent still alive
Implemented idea:
- parent creates socket connection
- keyboard interrupt kills parent and thus the socket connection as well
- children receive some specific socket error from the loss of connection

As we're all going about our various Easter, Passover, et al., family celebrations, I have the perfect solution to help train your families to stop asking you for help with mundane computer stuff:
Every time someone asks you to do/fix something, give them a full talk about what is going on in their computer around that system.
Don't forget you can talk about lots of things too:
- concurrency
- TCP IP / socket networking
- multi-threaded programs vs. single threads
- RISC vs. CISC processors
- Why linux is better than Windows or Mac
- algorithms
- logarithmic runtime
- teach them how to convert between hex, binary, and base ten
Really pour it on too. Soon they'll either figure out that you are a highly-skilled individual who is not their personal geek squad, or they'll be too afraid of a big lecture to ask for help.
Works with my in-laws like a charm.6 -
I'm not much a fan of JavaScript. In fact, I am not very fond of any dynamic language, but JavaScript is one of my least favorites.
But this isn't about that. I use NodeJS for all of my web serving. Why would I do that? Am I a masochist? Yes.
But this isn't about that. I use NodeJS because having the same language on client and server side is something that web has never really seen before, not in this scale. Something I really really love with NodeJS is socket connections. There's no JSON parsing, no annoying conversion of data types. You can get network data and use it AS IS. If you transmit over socket using JSON, as soon as that data arrives on the server, it is available to use. It gets me so hard.
JavaScript is built to be single-threaded, and this is rooted deep into the language. NodeJS knows this isn't gonna work. And while there's still no way to multi-thread, they still try their best and allow certain operations (Usually IO) to run async as if you were using ajax.
With modern versions of the language, the server and client side can share scripts! With the inclusion of the import keyword, for the first time I have ever seen, client and server can use the same fucking code. That is mindblowing.
Syntax is still fluffy and data types are still mushy but the ability to use the same language on both sides is respectable. Can't wait for WebASM to go mainstream and open this opportunity up to more languages!10 -
Windows not powering off when I press the shutdown button.
Mandatory long rant warning
Oh my fucking god, how many times have I lost my shit because of this fucking bullshit.
When I press the shutdown button, I want you to shut the fuck down you sorry excuse for an operating system.
Me and my friends want to hang out together, so I shut down my PC and walk over to their house, expecting an intense session of doing programming stuff and debating linux distros. Whatever the fuck we do when we get together.
I get to their house and pull out my laptop,, only its hot as fuck. And then I see it: the battery indicator is red. "What the balls?" I think to myself. I open the lid, and guess what?
WINDOWS DIDN'T FUCKING SHUT DOWN, AND IT STAYED ON THE POWERING OFF SCREEN ALL THIS FUCKING TIME. WHAT THE FUCK?
Now, my laptop has a bomb ass battery, so I didn't even bring a charger with me, and now I'm fucking stuck at a programming session with friends without a computer. FUCKING BULLSHIT.
If this was a one time thing, I wouldn't have cared so much, but this happened countless fucking times. Too many.
I would have deleted this cum socket of an operating system months ago if it weren't for the Windows exclusive software I need for school, and now that Steam supports games for linux, Windows has even less of an excuse to stay on my fucking laptop.
Windows is supposed be fucking simple, but linux takes it by a goddamn long shot. When I type "shutdown now" or "poweroff", linux shuts the fuck down, no questions asked. And if I ever need root permissions, I just type "sudo" instead of restarting the fucking program and requesting admin privileges.
Most of the software I use is compatible with both MacOS and Windows, and I already have Ubuntu installed on my laptop, so what do you guys think, should I butcher Windows off of my SSD and give MacOS a try?
Also, what is this magic? Ranting actually calmed me the fuck down... I need to start ranting more.
FUCK MICROSOFT AND FUCK WINDOWS, I WISH I COULD BURN TO FUCKING OBLIVION6 -
So my father has to deal with some vendors providing niche hardware and software solutions for a single department in the company.
Once the hardware finishes its work and transfers results to the managing PC, the PC has to upload those results to the server on the internet. The problem is that if no one's working with that setup for a few minutes the software in the PC can no longer communicate with the server.
Naturally, since idle time is in the equation, I thought of SO_KEEPALIVE (or whatever it's called in Windows). Wireshark confirms the absence of keepalive packets. However, the app doesn't seem to have any means to enable it... Hence the need to work with support guys.
One would expect the support to be professional, experts considering anything related to the app.
One would NOT expect to receive a call: "Hey, look, I was doing some googling on the internet... You might be right, enabling KA might help with the issue. We were discussing with our engineers and we tried to find some application that could enable KA on your computer. We couldn't find anything, but we believe that's the way to go. So give it a try and try to find some app on the internet that enables KA for our proprietary application". // everything in Lithuanian ofc.
I mean...seriously...?
I was startled to hear this suggestion. Since I expected them to be experts I assumed there's something IDK about Windows sockets -- could Windows enable KA globally, by-default? Did not find such a thing. Could Windows allow application A to control application B's socket options? Frankly, I'm too afraid to even look for this. I dislike Windows already. If this turned out to be true I'd probably become an anti-windows evangelist.4 -
Okay. So my dumbass boss took this project that had a steep timeline. I told him straight up, it won't work because we won't make the timeline. If we do this, I will be the one bending over backwards to deliver. I don't like to promise and fail. I got the oh don't worry let's just try. If we don't make it that's fine. Unfortunately that's not how I work. I refuse to deliberately fail. So I say okay and we begin. I suggested open source is the fastest way to deliver bit the fucked up part is, I am the only senior dev in the team. I will be expected to reverse engineer the open source app to connect our own deployment parameters. Use tech I have never used before. Connect frontend and backend. Handle dns bullshit. I have literally been working on Vibes and coffee for the past two weeks because ofcourse I ran into so many issues. Now I have an extension for Monday and I hate to fail. So I am not sleeping or resting just working on a fucking java app I didnt build and I am expected to make it work seemlessly on our production environment. I made some progress. Deployed frontend, deployed backend. Forgot to connect production dB so I decided to go with azure database for mysql driver since we have credits on azure. Now my java app is pissing itself over ssl handshake. I generate my keystore and add it and now java socket just times out. I want to pummel somebody or a punching bag that looks like my boss.15

HTTPS requests in most languages:
Import a couple of libraries, you may need to install a few as well. It's possible that you will need to initialize and set up the socket. Be sure to specify SSL settings. Create the connection, provide it a URL, and attempt the connection. Read the response, usually in chunks. You may need to manually create a buffer of fixed size, depending on if the language has buffer helper classes or not. You will probably need to convert the input stream response to a string to do anything with it. Close the connection and clean up any buffers used.
HTTPS requests in Python:

Well I WAS going to develop a side project on my day off today (a network of Arduinos and a Raspberry Pi) but the woman my wife hired to clean our house flaked-out, so now I get roped in to fucking housecleaning.
This was going to be an awesome day. Was gonna work on my project, chew some tobacco, and then go shooting, and out for wings for dinner. (where I live, chicken wings can be an entire meal)
Now I'm cleaning the shitter and scrubbing countertops because the little precious snowflake of a cleaning lady is in the middle of a (so-far) 3-day emotional breakdown.
Dear snowflake cleaning lady: Fucking learn IPv4 socket programming on the fly, when you've got an imminent deadline, and a crying, teething baby in the next room, at 3am, and don't fucking lose your cool at any point during all of this, then tell me about your fucking "emotional breakdown."3 -

I'll just start off with how I really feel. Fuck big corporations with their career robots and retarded practices!
Now for a story. So I work remotely for most of the time nowadays, since my company has as clients big corporations. Used to be embedded with said clients, but it became kind of painful to work with them all so I asked to be reassigned to a remote position.
Now for the retarded part: The fucking Klingons I'm working with have two tiers to their VPN, but won't let me have the full version because it would be too fucking expensive. I checked and it's fucking 50 bucks per year difference.
So for that the Klingons are making me code through a remote connection that has a "best effort" priority.
Fuck.
Anyway after 3 weeks of writing code at a 400-600ms latency I finally snap.
I try to use a proxy and it. I write one myself, gets balcklisted in 2 days.
After about another week of writing code through a fuck straw I start working on node socket with 2 clients and a server that encrypts the send data, and syncs 2 folders between my workstation and the remote one.
It's been a month now and it is still working. It's not perfect, but I can at least write code without lag.
Question for you peeps: What shenanigans have you pulled to bypass shit like this?3 -
You know what, let me jump in on the "I hate PHP" bandwagon.
A couple months ago I upgraded my mail servers unattended. Roundcube got fucked for a couple of months, and I figured.. fuck it, I can still use Dovecot for authenticating with desktop mail clients like K-9.
Recently I unfucked it, turns out that it was an issue with the sock file in php-fpm. That's also when I noticed that PHP apparently hardcodes in its current version in the bloody socket file. Because why the fuck wouldn't you? It makes upgrades so much fucking easier!!! Said no fucking sysadmin ever!!!
And today I upgraded one of my mail servers to Ubuntu Server 18.04, finally, after a lot of hesitation. Bad decision, because now PHP got fucked YET AGAIN.
Again an issue with socket files? I have no fucking idea. systemctl shows no failed services (because you know PHP, why would you fail your service with an error message instead of throwing a meaningless 502 Bad Gateway, right?!!) and looking at the config files, well the socket file got its new php-fpm 7.2 file (still got the fucking version number hardcoded in) and thus I changed that socket file location in /etc/php/7.0...
devRant may just have been my rubber duck.
WHY THE FUCK DO YOU STINKING FUCKING PILE OF SHIT CALLED FUCKING PHP KEEP THE FUCKING 7.0 DIRECTORY OUT THERE WHEN YOU'VE UPGRADED, WITHOUT EVEN HAVING THE FUCKING BALLS TO RENAME THE MOTHERFUCKING DIRECTORY TO 7.2, IF YOU'RE GOING TO HARDCODE IN YOUR VERSION NUMBERS ANYWAY?!!!!!
Bloody fucking pile of fucking junk!!!!18 -
Last time, working on a project with two mates at school.
I'm the one who knows how to read and understand correctly a doc for low-level c libraries (portaudio, opus) and working on sockets.
I make the barebone of our server. Co-workers should work on socket client.
After a week, the socket client is ugly, and almost unusable.
I rewrite the socket client in two days.
Co-worker, for a week : "the only contribution of Orionss is deleting my code" (it wasn't the first time)
In these moments, I would like to kill this guy1 -

I fucking hate printers. And printers hate me too.
I've been working as a software engineer for almost seven years now, and not a single day as a printer technician, which does not stop my mother from calling me each time a printer breaks down, as she did today. I hop over to her place, the printer is connected via usb into the ethernet socket, but she swears it's been printing an hour ago, and she hasn't moved a thing. - "weird", I think, "it must be connected wirelessly". Suddenly my sister, who's an Arts major, comes over, saying her printer broke down too - "cool so they're both wifi printers". I reset the router and my sister's printer springs back to life.
But my mom's printer, which is old and in bad shape (the printer, not my mom! assholes...), doesn't. It keeps on displaying a weird error message, and fails to receive any print job, whether wired or wireless.
I spent 15 seconds resetting the router, and 15 minutes troubleshooting mom's printer. Nothing worked.
I finally give up and leave the house.
Not a minute goes by and I receive a "your sister fixed the printer" text from mom.
I fucking hate printers.5 -

Coding has brought me into new communities and is the reason I have some new friends. I have to say, the best part is knowing how things work. I love knowing how this rant is sent to a remote devRant server thru a socket. How my rant gets divided up into an array of characters, each just a string of 0’s and 1’s. How my rant is stored in a database. How the devRant server connects everyone, and how everyone can (if they have to) use a VPN if it’s blocked, etc. And of course, how it’s all done securely. It’s great having that confidence going into the future knowing that you’ll be relevant and you have technological security. I love talking with people and explaining how things work. How when people say “stop acting so smart, you don’t know anything about X,” which to I reply “do you know how many fucking Xs I made.” Coding is great.

Asus announced their AM5 board X670E Extreme. The E already stands for Extreme, which makes it an Extreme Extreme.
My feeling is that AM5 will be extremely - expensive!
That's because the AM5 LGA socket moves cost from the CPU (formerly PGA) to the mobo, but AMD certainly won't drop CPU prices, rather the opposite, and then there's also DDR5 as cost driver, not to mention tons of PCIe 5.0 where we don't even have AIBs.
On the upside, that would finally end the days of GPUs causing a disproportionately large share of the system cost - if only because the rest gets more expensive.6 -
My project manager one time called me while I was waiting in the bank. He told me that the latest changes in the project I was working on were not deployed to production and they were having a meeting to demo those changes to the client later that day.
I had my laptop with me but it wasn't charged. I asked the security guys if I could use the socket used to power up the cleaning/sweeping machines and they didn't mind.
So it was me sitting on the floor in the bank hall using a side socket to power up my laptop holding my cellphone so I can use the hotspot and get internet connection deploying yesterday's changes to a production server.
Eventually, the client didn't attend the meeting that day!4 -
The worst type of debugging: Programming an MCU without a Serial Monitor.
Some Context: I've spendt today about 3h+ on getting an attiny 45 to read 3 digital values on 3 pins. So for every test I wanted to make, I needed to put the MCU inside a socket put this socket on a arduino and flash it. Then extract it from the socket and put it on a breadboard for testing.
After getting headaches for nothing making any goddamn sense, I ended up noticing that one input pin is a multiplexed reset pin with the reset having top priority and no way to change it. So whenever this pin should have read a low signal, it got held in reset! FML -

Last week I wired up my home network (including custom modem and routers) myself, because the stuff my ISP wanted me to use was garbage.
Luckily Germany has "router-freedom" so ISPs are not allowed to force us to use their device to dial into the network.
I did everything myself, because the 'technicians' they kept sending me were just idiots who didn't know anything, considering the highly paid job they are doing. Usually they told me, to get the device from my ISP, because my "Router" (actually a business grade, standalone Modem by Cisco, to feed my Router) didn't even have WiFi ( lol ). Also all Technicians didn't arrive at the agreed date but at some other time. I wasn't able to wait any longer.
So I did it myself.
Consider me something more like a student of theoretical computer science. Not actually supposed to be experienced with hardware stuff.
The ISP is serving me with a DOCSIS 3.0 Network based on the television cable network in my city. For some reason they are providing the internet-access to only one socket in the apartment, which has a rather uncommon "WICLIC" connector. After having trouble getting an adapter for WICLIC to common coaxial F-Connectors (used by every DOCSIS-Modem), I made one myself.
After setting up everything (not that hard, once the connectors fit) my modem told me, that, while I'm perfectly connected to the ISPs internal Network, I still can't access the internet.
So I called the ISP...
After getting ranted at, about that what I'm doing is illegal and only certified employees are allowed to do this and I will break more, than actually do good and that I can't just connect my own "Router" (again I needed to correct her: Modem) I hang up the phone.
Also she accused me of hacking their devices because I'm not supposed to see my IP address... (My Modem told me on its web interface. I didn't even need telnet for that.)
I went to the ISPs head office, told the first desk as many technical terms as I could remember and got forwarded to something like the main technician.
He was a really nice guy. The only sane and qualified person I dealt with at this company. He asked me for my Address and Device Model, I told him my MAC and last internal IP, I had seen and he activated my internet access within a minute.
We talked a while about the stupid connector that ISP is using in the homes and he gifted me some nicer adapters to connect my modem to the wall.
Why do ISPs hate their customers that much?2 -
** this means words are muted **
Friday:
I send a mail the client a Google doc with elaborate details about evaluation of an Android tablet from a Chinese manufacturer.
Monday:
The client is upset, he says "You say there is no GPS chip on the tablet while the manufacturer says otherwise"
Me- "I have clearly mentioned that it has a GPS chip"
Client- Opens the Google doc, points to a sentence. Looks at me like I did something horrible.
Me - **This guys is either word blind or something else is wrong with him, the line reads 'GPS chip available'**
Me- "Look, it says 'GPS chip available'.
Client- **Blinks n blinks again** "Alright, but why did you share a Google document, why not PDF, docx"
Me-**Politely** "You can download the document in any format, look I will show you..."
Client- "It should have been in the mail itself ideally"
Me- **WTH** "We normally maintain a document for such things to keep everything organised, but if you want I will put everything in mail itself"
Client- "Hmm.. do both from next time"
Me- "Alright" **BS**
Client- "Why is the new feature taking so much time"
Me- "As planned earlier, we going to deliver it tomorrow"
Client- "Why not today??" **Gives a strange look.**
Me thinking - **Enough**
Me- "See, I am trying to integrate a smarten with a socket connection, reading it's data via exposed APIs that are hardly documented, we need faster performance so I need to implement caching, multi threading, offline handling, multiple processes to avoid memory fluctuations, sync adapter to sync data...."
Client- "Ok ok ok, it's fine if you give working build tomorrow"
Me- "Ok, fine"

So, I move house with my amazing, already configured and stable router with built in VPN, DDNS, Port forwarding and DHCP addresses.
Received ISP shitty router at new address and want to use as modem only, so I go read the manual.
"Bridge mode requires you to configure your other router with PPPoE and the ISP's credentials"
Landline is not working, so I cannot call the number to retrieve my password. After 2 days of waiting, engineer visits, installs master socket, dial tone yaaay.
Call number to get password, automated voice message has such a bad sound quality that I cannot figure out if it's saying F or S, and there are two of those letters.
Put ISP router in bridge mode, set other router to PPPoE and put credentials, nothing. Try with F and F, S and F, F and S, S and S... Nothing. Put it back to dynamic IP address, it works.
I resign myself and manually configure everything I had on the good router to the ISP one. A few issues with my server and DDNS, but hey, internet works.
Start missing the other functionality, try the password idiocy again. Nothing.
Next day, go to work, talk to a colleague that lives close and has the same provider: "I just put it into bridge mode and it worked".
Go back home, bridge mode on ISP router, Dynamic IP on good router, no credentials. It works.

PSA: If you do reverse proxying stuff, prefer unix domain sockets over localhost internet sockets, if it's on the same machine (and if it's forwarded over ssh too). You can even serve HTTP as a unix socket.
Unix domain sockets don't have the overhead of IP, so generally speaking, data will flow to your other process with much less overhead.
I've recently stopped being lazy at this, and it's worth it.3 -
ok guys, im having a little trouble diving into this, anyone wanna help?
ive got a server set up, and a client app. the client has a the server's public key built in, and encrypts the aes key/iv and sends it to the server, simple enough.
but now, after the first socket connection is over, what do i do? ive got both sides with the same aes key, but the server has multiple keys for other clients. so when the first client connects again, how do i know which key to use?
ive tried implementing a session class where there's a session id, but it doesnt work because the id must be encrypted, too. can someone help a fellow ranted out?1 -

/** Null until this web socket is connected. Used for writes, pings, and close timeouts. */
private ScheduledExecutorService executor;
Dear boys and girls.
If you ever do this again and release this as a public library (even better - an official client of your solution, e.g. kuber-fucking-netes), I will get my way into dR's gateway servers, trace down your IP in nginx's logs, find your location, probably use some means to get your first and last name (you prolly have a domain registered under your IP anyways...), buy a ticket to your town, get to your home and wait for night to fall. Once it's dark and you're asleep, I'll make sure to leave a real nice, warm and extraordinarily smelly turd on your doorstep (I'll also make sure the process of manufacturing that gem is as noisy as it gets - you just have to bend the right way, and....).
Gents. If you really, REALLY want to make writes asynchronous, at least provide a way to either get a notification once the write is synchronized, or allow the user to handle the threads/executors himself!

With a recent HAProxy update on our reverse proxy VM I decided to enable http/2, disable TLS 1.0 and drop support for non forward-secrecy ciphers.
Tested our sites in Chrome and Firefox, all was well, went to bed.
Next morning a medium-critical havock went loose. Our ERP system couldn't create tickets in our ticket system anymore, the ticket systems Outlook AddIn refused to connect, the mobile app we use to access our anti-spam appliance wouldn't connect although our internal blackboard app still connected over the same load balancer without any issues.
So i declared a 10min maintenance window and disabled HTTP/2, thinking that this was the culprit.
Nope. No dice.
Okay, i thought, enable TLS 1.0 again.
Suddenly the ticket system related stuff starts to work again.
So since both the ERP system and the AddIn run on .NET i dug through the .NET documentation and found out that for some fucking reason even in the newest .NET framework version (4.7.2) you have to explicitly enable TLS 1.1 and 1.2 or else you just get a 'socket reset' error. Why the fuck?!
Okay, now that i had the ticket system out of the way i enabled HTTP/2 and verified that everything still works.
It did, nice.
The anti-spam appliance app still did not work however, so i enabled one non-pfs cipher in the OpenSSL config and tested the app.
Behold, it worked.
I'm currently creating a ticket with them asking politely why the fuck their app has pfs-ciphers disabled.
And I thought disabling DEPRECEATED tech wouldn't be an issue... Wrong... -
Any other language: Hey fuckface, you can't name this variable by a single letter, tf is wrong with you? use some descriptive shit.
Golang: lmao fuck u
I really find it interesting how we use short variable names for items in golang. Kinda makes sense when you think of it. Most of these items come up in short methods for which the mental model lets you know and remember what you are doing, they even make sense when going through the std lib in which that shit is all over the place. YET years of going by other languages has made me squint my eyes a bit in frustration every time I see it.
Say for example that a function is implementing io.Writer. What would you call the method parameter? you could argue that writer would be sensible since it has it in the signature, but what about when the io.Writer in itself is a file or a socket or whatever? writer would be funny or strange? nah fuck it just w, it makes sense, but x wouldn't. I find these points to make sense even if i don't like them.
Would, now, this practice be acceptable in C? you are supposed to write the same modular code with C in which you compose large functionality in separated units of code, yet I am sure this practice of single name variables is something that C engineers dislike greatly.
Are go devs just doing this out of blind love for their preference in languages? and how would this work if mfkers add generics to go(I hope not, Go is simple enough to understand in order to extend functionality through the empty interface, but that is a preference of mine as well)
The more I use Go the more I like it to be honest, I think the code looks ugly syntactically, but that is subjective as all hell and based on my constant preference for a language to look like Ruby, which even though it might not be everyone's cup of tea it remains to my eyes as the most beautiful language in existence, again, an obvious personal preference.18 -
I would like to call out the moron who decided to control docker through HTTP when the maximum time the server can take to finish the task is longer than the HTTP timeout.
If you expect things might time out, you don't use a HTTP request. You use a resource and poll it, or Websockets, or possibly SSE.
Shoehorning your API into a frame that obviously doesn't fit doesn't help anyone. Just admit that you don't know what HTTP is and use a regular TCP socket with regular pings.2 -
I built my first web server literally from scratch (standard socket lib) today! In Python <3.
It is able to execute php and get the stdout to use it in the Python script afterwards and make use of parallel connections.
Now to the real rant...
I am using HTTP/1.1. I want to use h2 (aka HTTP/2) tho. I am stuck on this. Found the papers to the specs of the h2 and spdy protocols, but they are not really helpful.

Today I have created a server application on Python Tornado which can forward TCP Packets directly to HTTP request queue without any intermediate caching.
Our remote IOT devices (microcontrollers with sensors attached) send sensor reading over TCP Socket to our server and all the connected web applications can show the data instantly using long polling and the above mentioned technique.1 -
Does anyone else get triggered when you use the python socket .recv() and the server does not return anything so the program just stays there indefinitely? For me, I can't even Ctrl+C it so I have to close the entire window. It's especially annoying when I start a server in the interpreter (quite a bit of lines) and I have to rewrite it afterwards.7

The AMD song, to the tune of Sam Riegel's DnD Beyond jingle:
You got the perfect casing
Its drive bays and supplies
But you need something to run your stuff
Cause you're late for that deadline
You click open a web page
You've heard about Phoronix test suite
And now you see a red company rise
In a field of blue and green
It's AMD! (AMD)
Yeah! AMD Radeon!
Yeah! AMD! (AMD)
Yeah! AMD Radeon!
You've got your motherboard
You've got your processors
And you've got Socket AM4!
It's AMD (AMD)

I've got a kinda basic networking question I can't quite figure out
How does a push notification work?
Like, on an Android app. A good example is an authenticator. Say I don't login to the service for 4 months.
Then, one day, I try to log into the web portal and it prompts me to accept the request on my authenticator app on my phone.
Immediately, there's a push notification on my phone.
Wtf.
Is there a socket open for 4 months? Does it send requests every few seconds for 4 months? I can't imagine that either of these options scale whatsoever: both horrendously waste bandwidth and server connections.
How the fuck does it work? I don't even have the first idea.7 -
How to run PHP in a container :
1. Begin a docker file for an existing php cron app (when all you know is php, everything looks like a php app)
2. Set the FROM.. Apt get update .. Do composer install
3. Builds the image
4. Discover I need git
5. Add git to apt get install step
6. Builds the image
7. Launch the php script
8. Fatal : use of undefined constant SOL_UDP
9. Opens the source code of the third party. The there's no mention of where that constant is from.
10. Spend many minutes online to find what's missing.
11. Find the PHP sockets page about that option. Digs into the documentation to find out that's missing from the installed PHP.
12. Find out I need to add a step to install the socket extension in my docker file.
13. Build the image again
14. Execute it, finally it works
15. Remember why I hate php
(for brevity I've omitted the even more complex part of having to set up zlib)

In high-school we had comp science classes which obviously hardly had anything to do with real stuff. In fact, our teacher was really clueless, so we decided to fool her. I made a tiny app that took a screenshot and set it as its background while being full screen and with hidden cursor. So it basically looked as if the computer was frozen. I also made it so pressing alt+f4 would set the background to a fake BSOD image. Next class we fired it up, the teacher tried everything to unfreeze the computer. She obviously failed, so we told her to try alt+f4. BSOD came up, she tried to fix it by hitting on the side of the PC. That didn't work so she unplugged it from the wall socket. We barely managed to not burst out in laugh, it was absolutely hilarious 😂

Follow up to this:
https://devrant.com/rants/6403741/
So we had today a meeting....
To restart the project, as the current state is garbage.
Turns out the whole team has after two weeks of being left alone with it - kinda like the rant says - zero clue how lucene works, what it does, what its for.
In case anyone of you wonders why some managers are micromanaging biatches, there you have it.
The whole meeting had more "oooh"... "ehm".... "eh"... and other fillwords just to cover the shame of not having any clue at all.
I'm really disappointed that a team of up to 5 people really thought they could pull a stunt of "fake it till you make it". Collectively. Really noone had a real clue.
Now to an interesting discussion: How would you devs reprimand them?
:)
Just curious. Firing is out of option, for several reasons, e.g. law.
Serious answers, I would be really curious. :)
I'm feeling sad for the socks metaphoric in the last rant btw.
Even a cum socket deserves more dignity than them imho.6 -
TD;DR: I have school instead of vacation but 5 hours of spare time. I got my laptop with me and I'll work in school.
I didn't want to take part of the course-trip with the 12th graders (my course sucks, there are too many assholes for the neutral people to compensate). After speaking with the director, and the only condition was to tell the course why. I did deliver them a nicely put "fuck you, you bullied my only friend out of this school" and now is the time where I visit the 11-graders while the other 12-ers are on "school vacation".
I got a "new" plan for the courses I should visit. Today, Wednesday, I have 5 FUCKING FREE HOURS IN A ROW. Oh yes, baby, the teacher generating the plan hates me as well. (He really does but it's probably just unlucky not his fault).
So today, I decided, I would take my heavy-ass laptop with me, in a laptop bag, which doesn't fit into the school bag I have and my laptop doesn't fully fit in the laptop bag as well (sticks out), that's the perks of having a laptop!!
— so I can work on my (I wanna say this once in my life without being a professional) "CLIENTS PROJECT" - the funny thing is that the client is a (really fucking good but small) advertising agency and too lazy to design their own website. Since I had my internship, they know how hard I *can* work even without being payed. Now they do wanna pay me but that's another story.
I'm on the bus and I have this monster of a bag which isn't lighter than a freaking huge bag of rice and I'm so fucking excited for this day. The library is my best friend. Hopyfully I'm going to find a socket for power..
Sorry for so many commas, I'm german. :D3 -
Nice. I have now wasted about 8 hours or so debugging to find out why my (fully functional) program wouldn't receive messages (from an FTP server through a socket). It just received an timeout from the server after 300 seconds. Then I discovered that my messages didn't include '\r\n' in the end.

A long time ago in a decision poorly made:
Past me: hmm we're having trouble getting IT to give us a new build machine with the new compilers.
Past me: I know we'll just use one of the PCs that belongs to a member of the team to tide us over.
[2 months pass]
Present me: that's odd, Jenkins is really slow today.
[Several minutes pass]
Present me: holly shit fuck; it's building the whole weekends worth of builds at 9am on a workday and eating licenses like a cast away that suddenly teleported to an all you can eat buffet.
Present me: [abort, abort, for the love of fuck abort]
Present me: contacts IT, they can't find any problems, wtf happened.
Present me: discovers team member turned off his machine on Friday and builds had been stacking up all weekend.
Lessons learnt: disable power button on team members pc and hire a tazer guy to shoot whenever someone goes near the wall socket.
1 hour lost and no build results for the last 3 days.
It's looking like a bad morning

Some people really get paid to not think at all! Licensing server stuff got changed by one of our suppliers. Licensing client basically screams nonsensical errors when wanting to move a license.

Why do you push online updates before the local ones! Fucking electrical socket impregnators!2 -
Oh, all sorts, but the one I always quote at her is the time she couldn't plug her laptop in because it had, I quote, "A funny plug on it that doesn't quite fit."

So I was looking into phone app development again (as you do) and I'm working on a simple QoL app for me and my SO that will help us automate some home management and finances stuff. Naturally I delved down the rabbit hole deep and wanted to have push notifications so we don't have to check the app periodically to know when certain things happen... Oh boy... Why is mobile development so convoluted, especially if you don't want to rely on Google Services...
It seems that the most accepted way of doing this is Firebase (FCM). Well me being me, I refuse to use google services for this and I prefer self hosted solutions (for data privacy reasons) which eliminates most products out there.
It also didn't help that my framework of choice is Flutter/Dart, because fuck Android Studio and the insane buggy XML stuff and fuck Android and it's constantly changing APIs...
Well In the end I decided on a rather simple solution and self hosted an AMQP service (RabbitMQ in my case, as I have some experience with it already) and implemented a foreground service in android platform specific code on top of my flutter project to kickstart it and made my phone a queue listener... This now means I can push notifications from my server to the Messaging Queue and it will be pushed into my App automatically!
One thing I found out on this journey was that Android now kills most background services and enforces foreground services to have a visible notification in the status drawer... which I actually approve of. It's a bit annoying that you can start a reliable background service, but I'm absolutely on-board with long running processes started by my apps are constantly visible...
Long story short, I love reinventing all the wheels, especially if it's for free and private... And I also went to sleep at 2AM again because this took longer that I'd like to tune... but it works, and it's google free...
I'm thinking of trying to package this up as a flutter module later, but first I want to do testing on battery life and the general life cycle of the service. RabbitMQ says they have the client library optimized for long-lasting connections and it should be just using a tcp socket, which should pretty much be what all the push notification services are doing anyway. I'm also not completely satisfied with how the permanent notification looks.. it isn't collapsible like some of the other ones from other apps and it's about 2 lines high instead of single line... which is something quite annoying and I'm struggling to find any relevant docs on how this is done other than possible making a custom Notification Style... but I just can't believe that everyone is doing that.. there must be a built-in somewhere -_-... Ugh Android is hell...
Anyway, if any android devs here have some hints, tips and tricks on how to handle this type of background/foreground process stuff and I'm doing something wrong let me know, cause googling this shit is a nightmare too!6 -
So I am making a real time chat app using MERN and socket.io but I was disappointed to discover that the newer version of socket.io ie 2.2.0 fails overtime on Chrome.

Has anyone else found that not all USB C inputs are the same? You can't just buy an cable and expect it to plug into any socket.
1. I replaced the cable for a power pack, but the new one didn't fit my OP6 socket well, no clicking and have to push it in very hard to get it to charge, and still eat to fall out
2. The pixel 2 cable fits it nicely and all cables are ready to plugin and work
3. I tried charging my new Pixel 4a with ur though but very hard to plug in. Had to install the charger and cable that came with.
4. Amazon Fire takes all of them nicely and send all the others can use the cable that came with it too8 -
Question: which is better approach?
1. Use push notifications to tell react website that new data is available
OR
2. Use SignalR (similar to socket.io) and push data in real time?
The down side of SignalR is server needs to map connections --> use more memory while push notifications doesn't require that12 -

Fuck this shit. Any socket connection on JIO's fucking network gets dropped after 5 seconds if no data is sent. It's working on any other network. Wtf is going on???
Does anyone have any idea on this?
If someone has jio network please go to https://www.websocket.org/echo.html
And connect and check how long until it gets disconnected. Would be greatful if someone can validate this.
The project I am working on uses websockets extensively and this thing is screwing it up. I have temporarily set websocket ping interval to 3 seconds but what if the f**ckers over at JIO decide to start dropping connections every 1 second?7 -

Python3's asyncio is awesome.

Found my grandmother's Vista laptop from '07. It has 3 problems:
1. Battery lasts 15 seconds at full charge (not a shock)
2. Plastic shell around screen is cracked (not badly, likely fixable with plastic welding)
3. IT'S SLOW AS FUCK
Point 3 is strange, considering the specs:
AMD dual-core CPU at 1600MHz (better than MY laptop...)
Some NVidia onboard GPU thing (no clue)
2x 512MB DDR2-L (immediately swapped out with 1x2GB and 1x1GB, the most we have at the house)
What I noticed, though, is that it's got a SOCKETED CPU (a rarity only like 3 years later), specifically an S1 socket. There's an AMD Phenom quad-core clocked at 1800MHz with that socket, for $16 on eBay no less!
However, it's a different processor family, so I don't know if it'd work in the board...
Anyone think it'd work?9 -
Bloody fucking Android! Updates, updates and more updates! My development Nexus 5X won't allow me to sideload apps since it updated... Hello, printf debugging! Goodbye, profiler and debugger!
My hate for Android grows with each version after 4.0.$something... 2 was shit, I missed 3, 4 was OK, and since then it's going steeply down.
And don't get me started on Material Design...! Good luck figuring out what's a button and what's a label...
And what's up with the "let's keep all apps running all the time to save a few ms on start" philosophy!? Who thought that is a good idea!? Yeah, System.exit(0) works, but... Is it so hard to determine when it's not needed anymore (has no services running etc.)? Why should a web browser (for example) stay in memory after I quit? Minimize is a thing (Home button), why make it so confusing?
Another thing - feedback-less async tasks - why? I like to know when it is working in the background... How the hell am I supposed to find out if it is supposed to do this or if it is frozen?
And Android deciding to kill your process whenever it pleases without any callback... Happened to me once with an Activity in the foreground (no exceptions anywhere in my app, it just quit). How do you do IO properly? It seems you can't guarantee some file or socket or something that must be closed doesn't stay open (requiring to restart Bluetooth 'cause the socket wasn't closed, for example)...4 -
you think that when data comes from server you can read it? well you are wrong! you have to waiForReadReady(0ms) to be able to read data which is already here...

Relatively often the OpenLDAP server (slapd) behaves a bit strange.
While it is little bit slow (I didn't do a benchmark but Active Directory seemed to be a bit faster but has other quirks is Windows only) with a small amount of users it's fine. slapd is the reference implementation of the LDAP protocol and I didn't expect it to be much better.
Some years ago slapd migrated to a different configuration style - instead of a configuration file and a required restart after every change made, it now uses an additional database for "live" configuration which also allows the deployment of multiple servers with the same configuration (I guess this is nice for larger setups). Many documentations online do not reflect the new configuration and so using the new configuration style requires some knowledge of LDAP itself.
It is possible to revert to the old file based method but the possibility might be removed by any future version - and restarts may take a little bit longer. So I guess, don't do that?
To access the configuration over the network (only using the command line on the server to edit the configuration is sometimes a bit... annoying) an additional internal user has to be created in the configuration database (while working on the local machine as root you are authenticated over a unix domain socket). I mean, I had to creat an administration user during the installation of the service but apparently this only for the main database...
The password in the configuration can be hashed as usual - but strangely it does only accept hashes of some passwords (a hashed version of "123456" is accepted but not hashes of different password, I mean what the...?) so I have to use a single plaintext password... (secure password hashing works for normal user and normal admin accounts).
But even worse are the default logging options: By default (atleast on Debian) the log level is set to DEBUG. Additionally if slapd detects optimization opportunities it writes them to the logs - at least once per connection, if not per query. Together with an application that did alot of connections and queries (this was not intendet and got fixed later) THIS RESULTED IN 32 GB LOG FILES IN ≤ 24 HOURS! - enough to fill up the disk and to crash other services (lessons learned: add more monitoring, monitoring, and monitoring and /var/log should be an extra partition). I mean logging optimization hints is certainly nice - it runs faster now (again, I did not do any benchmarks) - but ther verbosity was way too high.
The worst parts are the error messages: When entering a query string with a syntax errors, slapd returns the error code 80 without any additional text - the documentation reveals SO MUCH BETTER meaning: "other error", THIS IS SO HELPFULL... In the end I was able to find the reason why the input was rejected but in my experience the most error messages are little bit more precise.2 -
Dear Lord, please stop people from enforcing standards and bypassing them themselves.
Take kubernetes for example. Since v1.24 CRI has been announced as the standard, and kubernetes is shifting to live by it.
But it's not.
Yes, it's got the CRI spec defined and the unix://cri.sock used for that standardised communication. What nobody's telling you, is that that socket MUST be on the same runtime as the kube. I.e. you can't simply spin up a dockerd/containerd/cri-o server and share its CRI socket via CIFS/NFS/etc. Because kube-cp will assume that contained is running on the same host as cp and will try to access its services via localhost.
So effectively you feed the container via a socket to another machine, it spins up the container and that container tries to
- bind to your local machine's IP (not the one's the container is running on)
- access its dependencies via localhost:port, while they are actually running on your local machine (not the CRI host)
I HOPE this will change some day. And we'll have a clear cut between dependencies and dependents, separated by a single communications channel - a single unix socket. That'd be a solution I'd really enjoy working with. NOT the ip-port-connect-bind spaghetti we have now.4 -
What do you guys think is better: socket, SocketServer or Asyncio??
In my experience i found socket performing better than the SockerServer, but i have heard that Asyncio is even better.4 -
THIS is powering the internet:
"[...] was a protocol number, similar to the third argument to socket today. Specifying this structure was the only way to specify the protocol family. Therefore, in this early system the PF_ values were used as structure tags to specify the protocol family in the sockproto structure, and the AF values were used as structure tags to specify the address family in the socket address structures. The sockproto structure is still in 44BSD (pp. 626-627 of TCPv2) but is only used internally by the kernel. The original definition had the comment "protocol family" for the sp_family member, but this has been changed to "address family" in the 4.4BSD source code. To confuse this difference between the AF_ and PF_ constants even more, the Berkeley kernel data structure that contains the value that is compared to the first argument to socket (the dom family member of the domain structure, p. 187 of TCPv2) has the comment that it contains an AF_ value. But some of the domain structures within the kernel are initialized to the corresponding AF value (p. 192 of TCPv2) while others are initialized to the PF value." Richard Stevens 'Unix network programming' -

Jesus Christ , how does one connect to a third party websocket stream in Laravel. It seems to be so damn complicated with the involvement of Pusher, Broadcast, Echo and a bunch of other useless packages. On Top of that there are no tutorials on this, everyone is busy building a chat app and even then i tried following along, it doesn't work. Does anyone know how to do this?
In python, it is as simple as this
import websocket
SOCKET = "wss://stream.binance.com/ws/..."
ws = websocket.WebSocketApp(
SOCKET, on_open=on_open, on_close=on_close, on_message=on_message
) //you get the damn data
In Laravel, it so bloody complicated. -

Anyone with good understanding of hardware and/or an operating systems network protocols please assist me. I have questions
When using socket api I know it’s not the actual sockets sending the data but the socket api tells the network protocol to send, receive, listen, connect, etc well what I want to know is how that networking protocol works within the operating system
My second question is more an extension of the first. After the operating system knows what the socket api wants to do and wants to do it how does the transmission and receiving work on the physical layer within the hardware
Idk if what I’m asking makes sense. But if anyone also has any resources or a link that’ll help me on the subject I’d appreciate it. I haven’t found anything on the subjects myself19 -

Need advice about protecting ddos via iptables and whitelisting. Currently I launched my gameserver and am fighting against a massive attack of botnets. Problem was solved by closing all ports on my gameserver linux machine and shipping game.exe with injected c++ socket client. So basically only gamers who launch my game exe are being added to firewall iptables via the socket client that is provided in the game exe. If some ddosers still manage to get inside and ddos then my protection is good enough to handle attacks from whitelisted ips from inside. Now I have another problem. Lots of players have problems and for some reason shipped c++ client fails to connect to my socketserver. Currently my solution was to provide support in all contact channels (facebook,skype,email) and add those peoples ips to whitelist manually. My best solution would be to make a button in website which you can click and your ip is whitelisted auromatically. However if it will be so easy then botnets can whitelist themselves as well. Can you advice me how I could handle whitelisting my players through web or some other exe in a way that it cant be replicated by botnets?1

Question about linux iptables. I am currently blocking all access and whitelisting only when my users launch my software. When software is launched a socket client is also launched, it connects to socket server, identifies itself with a password and disconnects. If given password by socket client is correct, then socket server whitelists the users IP by executing the following command: " iptables -I INPUT -s userIP -j ACCEPT".
My problem is that now I have lots of duplicates of IP's whitelisted and as far as I've heard I should not go over 25k iptable rules.
So my question is how to check if ip is already whitelisted, in order to avoid duplicate iptable rules for for same IP?
Obvious solution would be to store whitelist somewhere (mysql/txt) and double check before whitelisting ip, but maybe there is an easier way to do this?4
