Hobby time...

more like clients tinkering with their own website 😂

Story, !rant.

This memory came up as I was commenting on another rant, and thought it was worthy of a better retelling.

So about a year or two ago, I had just gotten a Software Defined Radio, and was tinkering with it and looking around for cool stuff I could do with it. After stalking planes for a while (caught a 747 over my area 😎) I saw this program that decoded satellite images of earth, coming from the NOAA satellites. I thought this was amazing.

So I waited until one was over my area and let the software do its magic. The image was not great, since I had this set up on the first floor and there was a lot of material between me and the satellite.

So I came to the brilliant conclusion that I'd leave the program on automatic more (it will start sampling when the satellite is near) on my terrace, which should yield better results, right?

Perhaps. Who knows. Anyways, couple hours pass and we are running late to a family dinner. So we book it. Family dinner was great, good food and all, and was having fun, so never thought about my poor laptop, sitting alone in the night.

But then, when I was walking home in the rain... It hit me. I started running. I couldn't believe what I had done. Fast forward five minutes, and I'm out of breath, but home. I run upstairs, and see the laptop just sitting there, lid open, no lights on, and of course soaked right through.

I couldn't believe it. My only piece of tech at the time, and my only avenue for programming, gone. And I was 15, so I wasn't getting another one any time soon. Took it inside and drained the water out of it, and just left it there lying on its side.

Next day it worked just fine 🤣 the battery on my laptop only lasted max one hour, so by sheer luck it had lost power before the rain came. That is the one time I have to thank that battery for being such utter trash.

It was the year 2000, when IE was considered awesome. The internet then was slow and expensive and I had a quota about half an hour a day for dial up.

I discovered that I could view the source code of any page and while it looked rather cryptic I slowly started to understand how it worked. After months of tinkering in Notepad, I was able to write some html and JavaScript. No books, no online tutorials, just pure act of curiosity and a sense of adventure.

How to write JavaScript properly had to wait for another decade after an engineering degree, a dozen other languages, and new browser. But those tinkering days were what got me into coding.

Like most people I needed some extra cash during uni, so I proceeded to learn CSS + Photoshop (yeah, I know). Followed by PHP and WordPress.

It can be a very shitty platform until you realize that you can stop combining plug-ins from all over the place with dubious code quality and roll your own.

Anyhow I kept at it until I was able to join a niche company doing a quite popular caching plug-in for WP (yeah, W3 Total) when I suddenly became *very* interested in anything and everything performance.

This landed me a very cozy consulting gig in the Nordics - they were using WP for an elephant-traffic website and had run into a myriad of perf issues.

Fixing them and breaking the monolith awarded me with skills in nodejs, linux, asynchronous caching among others.

I was soon in charge with managing the dev boxes for the entire team, and when the main operations dude left, I was promoted to owning the entire platform. (!) Tinkering with Linux for most of my life really came in handy here. (remember Debian potato?)

Used saltstack + aws cloudformation to achieve full parity between all environments. Learned myself some python and all various tips and tricks which in the end amounted to 90% reduction in time-to-first-byte and considerable cost savings.

By the end of the 2yr contract I had turned myself into a fullstack systems engineer and never looked back.

Lawyers not getting along resulted in us having to abandon NewRelic, so I got to learn and deploy the ELK stack as a homegrown replacement, which was super-fun.

Now I work in the engineering effectiveness department of a Swedish fintech unicorn where all languages under the Sun are an option (tho we prefer Python), so the tech stack is unlimited. Infinite tools and technologies, but with strong governing principles and with performance always in mind so as to pick the right tool for the job.

It's like that childhood feeling when you've just dumped a ton of Lego on the floor and are about to build something massive.

I guess the morale here is however disappointed you feel by your current stack - don't. Always strive to make things better, faster, more decoupled, easier to test, etc. and always challenge yourself to go outside the comfort zone.

I didn't scream.. just told him to jump off of terrace..
What ticked me?! He was a support guy..slowest mofo ever..
I was in the middle of fixing major fuckup on prod, when our VPN to client disconnected. I rushed over to support to ask if it is 'just' an expired session (which he was in charge of renewing but constantly fucked up) or if there is some other problem, so I know how to proceed..do I need to contact our sysadmins, client's support guys etc..
He
started
to
slooooooooowly
explain
I
am
not
the
only
one
with
VPN
problems
...
Was that what I asked you?! // he had an annoying habit of slooooowly talking and explaining unrelated things & personal stuff that bothered him & most of the times he chose the most time sensitive period to drone off..
So I cut him of saying, that others were probably not 'tinkering' with production and that I need this back ASAP, so if he could tell me when the session will be renewed or if there is something else problematic..
He said he will check..I didn't move.. he looked at me insurprise, you want me to check *NOW*?! Yeah, it's urgent.. He proceeded very very veeeery slooooowly, taking the support phone../* he was even eating sandwich during that, so only one hand free, typing one letter at a min */
I was finaly notified that the session expired and that he will fix it soon (meaning in 15-20mins o.O which should not take him more than 5).. and was like 'can I do sth else for you'?! Yeah, do the backflip.. you know the rest..

My father while I was tinkering in the workshop :
"You see, I think you chose the wrong studies, you would have liked something else like material science a lot more."
At this moment my face took a question mark shape.
"Wait.. What? I mean... You know, I quit mechanical engineering to computer science, I actually made this decision because I thought it was better for me."
Him :
"But you will never have a good job in it. Material science for example is the booming industry, it's the future."
"What the... No, just no. Every year at my university several mechanical engineering students get thrown out because they can't even find an internship. Whereas most CS students find more than one and end up sharing job offers with their friends. And talk about an interesting job, in the mechanical domain everything already exists and it's just a matter of applying the same boring standards over and over again, when it's not just pure technician managing. In CS new technologies and tools appear regularly, keeping it interesting because evolution is hardly limited by real life physics, just by one's brain."

Pissed me off.

Look what arrived today. I'm so excited to start tinkering. I might install Kali Linux on another micro SD card

Been tinkering with circuits all afternoon, and then i made the mistake of eating some pastry right off of my table. Pretty sure i ingested like half a roll of solder lmao.

Basically: Shoutout to my dad!

My dad's not an engineer or anything. But he likes building PCs and has a bunch of tech at home.

Well, thanks to him, I had a PC very early on, and of course, I did the typical skiddie stuff it, aka "fake batch virus haha funny" and playing Minecraft.

Well, at some point, after tinkering with mods to enhance the quality of gameplay, I found the ultimate mod: Macro / Keybind Mod.
This mod allows you to bind stuff to keybinds, such as commands or chat messages, or... Macros.

This mod has a custom macro language. (Hint: This is where the fun begins)

Another mod I used was AutoSwitch. However, that mod required a "core mod" (aka library installed in a dumb way). I thought, "why do I install 2 mods to get 1 thing? dumb", and made an ugly macro with lots of nested if-elses, which perfectly emulated AutoSwitch behavior for the Minecraft version I was on.

Yup, I basically got rid of 2 jar files in my mods folder by making my own ugly macro.

The fact that I recreated something in an obscure language, having not even coded any program before, made me grow interest into actual programming languages.

In the middle of tinkering with live database. Got to take a dump. 2 min later 😂

Yaay, after several hours of tinkering I finally got a simple chat over TCP working in rust. I'm happy, I like rust :)

A classmate's earphones once stopped working, I went to go look at it. After a bit of tinkering, I said, "The speakers on these are toast, you'll need a new pair." Then, some random kid grabbed the tablet mind you, and not the earphones, played in the settings, and said "Fixed." I then told them, "This is a hardware issue, not a software issue." What's worse? Some people said "So, software and hardware are the same thing."
Mississippi is just full of computer Illiterates.

I miss when my job was just about coding, I could spend entire workdays writing C# or TypeScript while listening rock or metal with few meetings in between, being very passionate in programming and computers sometimes I found was I doing so engaging which I spent more than my 8 hours workday on company's code base trying to improve it and my older coworkers were very happy with my code.

Then a "promotion" happened, I went to work directly with a client, a huge enterprise which is working on renovating his internal software and here the fun stopped. Long useless meetings are a regular occurrence, there are absurdly long procedures to do everything (for example since CI/CD is leaky we have to do dozens of workaround to get a microservice deployed) and having very little written documentation this gives an huge advantage to people which actually enjoy to spend their entire workdays on a MS Teams call over "lone programmers" like me which actually feel significant fatigue in doing that (alone sometimes I was able to log 12+ hours of programming daily between work and personal projects while after 3 hours of PP I feel drained) since the information passes in meetings/pair programming and I dread both.

I feel which my passion is still there, I still enjoy coding, tinkering with Linux and BSD, broadening my knowledge with technical books and having passionate conversation about tech but I dread my job, sometimes I try to look at it under a more optimistic eyes but most of the times I just end disappointed.

My NDA prevents me of revealing a lot but here we go...

Hi,
during a 2 year hiatus after High School I decided to study CS. Coming from a third world country with no prospect of getting a nice job without breaking my back or getting spit on by overconfident CS geeks who now actually make a living wage there, I decided to study abroad.

I immediately realized what I have been missing... the culture, the people, the happenings,... I have been starved of LIFE

Anyways, I got the language pretty much down, uni is pretty hard but doable and I got the unthinkable... A JOB. I am currently a working student for a year at a multimillion dollar global conglomerate, doing what some may think of as scripting/data tinkering. I get payed more than both my parents combined, which is why they don't know anything... 😂 (yet, gotta ease em into it).

Now I have gotten my contract extended, which shows that I am doing a decent job there, the boss is firm but chill, coworkers are helpful and resourceful.

But what really grinds my gears is that I am mashing code together whilst googling my brain out, but I am not gaining any skill...

Now comes my grievance, the bane of my existence, the evil Morty to my Morty,... GitHub.

In this professional surrounding, where I got handed a $2,5k notebook and a overly huge paycheck, I never use Git (because we have a proprietary, internal, and very transparent alternative (transparent for the higher ups 😬 ))

I always wanted to contribute on GitHub, but I get very intimidated by the projects there and their scopes, people are waaay too knowledgeable in comparison to me and I will most certainly screw something up and embarrass myself. Since I am very self-conscious and awkward I would most probably just delete my profile there and lurk in the shadows again.

I need help, not only for my mental health, but also to expand my skillset and improve myself, since skill is the only thing I can still acquire.

Does anyone know where I should start as a overglorified python script-kiddy who still thinks 1337 is cool and mr Robot is a decent show?

Thanks,
@rn

Gotta admit. Amazon fire tablets are awesome for cheap tinkering and installing custom firmware in it. Using 7 of them to use at my super efficient smart home (😎) and they don't break at all...
I wish they allow direct international shipping tho...

Do you guys think it’s time “Hackers” gets its 2020 remake? I know it was cheesy for its time (1995) but 8 year old me was INTO that music video montage direction and that movie inspired was what inspired me to get into tinkering with electronics/embedded systems.

Rewatching it tonight and the casting is so on point, too.

Childish thing really, and slightly related to my current job

Was working on a small pet project (it was a website really) back in college, and collaborating with another friend on it who lived in a different city. Had to show him my progress but he wasn't a programmer, just had to show him how much front end part is done and the functionalities till that time. Of course hosting it online was the best solution, but I was a student and broke.

So I got this python script caller pagekite which would make my laptop into a server for the duration I run the script. It ran but I couldn't manage to show him the site for days since I didn't know where it was connecting to. (No one had any docs on it back then)

Did some tinkering and saw that it connects to localhost, so I fired up my xampp server and it worked as I wanted it to :')

Since that day, I decided that I want to be a developer and learn and implement more of such things.
Moral: the smallest, insignificant things can sometimes give you the most happiness.

Have u ever opened a website and thought if u had the chance, u would kill their fucking frontend guy. Ya well i had to open a lot of such websites on a daily basis , so i found a extension that lets me change the website's css. After tinkering for a while, i came with this for the homepage of duck duck go.

I work with J2EE every day, especially Spring and Spring Boot.
I like it very much but when I am home I love tinkering with C++ (even tough I am a beginner in this language).
Is anyone else like this? It's like C++ has a misterious charm for me, not sure why. I also enjoy haskell and erlang, but keep at getting back at C++.

I did a project once and it came back to haunt me - this is how I got the job I have now:

I was already working for the company, in the second year of my vocational training as an electronics technician when I got a assigned The Project.
In brief, The Project was a kind of measurement automation implemented with some arduinos. I was tinkering with them at the time in my free time so they must've thought 'Hey, great, she can do that, so she can also do The Project!'

Just that I couldn't - after investing nearly a year, getting frustrated because of the lack of time, support, knowledge etc. The Project died quite unceremoniously and I resumed my training normally.

I just wish devRant already existed back then, it'd have made up for some spectacular rants - The Project was fucking nerve-wrecking due to incoherent behaviour by some hardware and I had to battle the whole big, ugly thing more or less alone as an apprentice.
If it hadn't died at the time it did I feel like I would've brutally murdered it with a shovel - that is, if someone actually would've cared enough to buy me a shovel.

But it ended and I let it go.

In the last year of completing this vocational training, my feeling of "This is not enough" and growing boredom with the routines of my future job had manifested. I wanted to go back to university but also continue working at the same time.

I wasn't ready to do freelancing nor did I want to quit at that time - most people there are amazing and I'm still learning much from them - so I asked early for a student position and got one.

And to get some continuity in my work, it wasn't just any student project I was assigned to but The Project. It came back alive, laughing at me, leaving bodies of dead electronics in its wake, after all these years.*

And that's how I got my current job.

*(They asked me if I was OK with it and they dropped the Arduinos and other hardware in exchange for a bit more software. Also I have a team of great engineers which I can ask for help anytime should I get stuck, so I got that going for me which is nice.)

After spending my entire holiday vacation fucking around with the one language that really digs with my state of mind (Ruby) when developing and having to do some quick troubleshooting on 2 of our applications (Java and PHP respectively) I can honestly say: I legit don't want to go back to that ever again.

But money means more to me than my own personal biases. I have delved in some of the most HATED platforms that developers could normally ask for in terms of work. And have only done some very basic (fucking obnoxiously basic) consulting in terms of Rails, to the point that it might not be even worth putting on a cv. But fuck me man, if I could just fuck around building rails solutions for a living, from the frontend to the backend, I think I would for once be happy with the things that I work with with things more than monetary pleasure.

Y'all know your boy, I ain't no neckbeard, but I fuck with things that a lot of others don't, to me Lisp dialects and Smalltalk are gifts from dev heaven, and I have thrown out Clojure in production (my app is still chugging along just fine at work thank you very mucho) but in terms of pure web development, I have never been happier than when I generate a rails project and start tinkering around.

Sigh.......here is to hoping that maybe I will eventually open my own rails shop.

I love python, but I hate dealing with python dependencies, especially on Windows.
I was tinkering and researching with neural networks, so I wanted to try out pybrain. I wrote my project, with pybrain installed via pip, and tried to build it.
Oh, what's that? Pybrain doesn't work with python 3? Well I'll download the version that's supposed to. Oh, that version has a deprecated numpy api? Let me just install those other resources. Oh, that requires a broken module that has no publicly available source?
Let's try python 2. Oh, now that's working, I just need to export environment variables for some "bls source". Some quick Google searching and the only solution that would work is building a bunch of cywgin modules by hand. That's fine, I have an ubuntu partition.
An hour later I'm compiling FORTRAN dependencies on Ubuntu.
Coding time: 1 hour
Dependency time: 3 hours

It's dangerous to be curious. And have time to spare.

This morning I was in THAT state and decided to spin up kubernetes inside an... Alpine docker container.

The day has almost passed and I think I'll have enough tinkering left for the night.

yay........... I guess...

Toughest part of dev interviews? There are multiple I can think of.

Getting an interview altogether in this dumpster fire of an economy.

Negotiating salary (i.e. prevent getting a low-ball offer)

When the interviewer is a dev themselves and they get on a power trip and ask you the toughest/trickiest questions.

Convincing the interviewer that something you don't know now can be learned later just by googling and tinkering around.

Trying not to burst out in anger when you get asked stupid questions like "Why aren't you married?"

'Hey, I've learned proogramming from this book[...]' - said nobody ever while being honest to himself.

I can't decide on a linux distro because all I've tried are great. Seriously.

I'd call myself a novice-to-intermediate linux user (heavy on the novice part) and since I work as a web developer it's been a great learning experience to use the same OS on my workstation as the webservers my projects run on. (Ie I started out with Ubuntu and a LAMP setup).

The thing is I distrohop ad infinitum... Feels like I've tried out every desktop environment known to mankind (I just can't stop myself when I see a new one or a new take on an old one) and I've dipped my toes in Arch territory to. Loved Antergos when that still was a thing. Found EndeavourOS this weekend, kernel panic ensued. I'm a noob with sudo and that's never a good thing. 😆 (Try out in a virtual machine first you say? Bah. Where's the fun in that?!)

So now I'm on Linux Mint w Cinnamon because why not. (Because it's sluggish and boring, that's why...) I had to just get something up and running quickly so I could get back to work. 😬

But one day in and I'm realising I actually miss GNOME. And Ubuntu feels like home. I would feel much cooler using Arch but honestly I don't think I can be trusted with it. I love tinkering with settings, look and feel and whatnot but I can honestly do that just as well in an Ubuntu/GNOME environment.

Maybe Pop!_OS... could be something for me. 😏

Ooh... one I can participate in...

My dad was a Java developer, which primarily got me interested.

Back in early 2012, a favorite MMOG of mine shut down and I was interested in how it worked. I was 13 at the time. A friend of mine, on hearing of my interest, emailed me a bunch of links including Chris Pine's ruby tutorial and TheNewBoston.

From then on I tinkered a little with a bunch of different technologies, picked up a few programming books, and now we're here. I've made a little money as a Java developer and I'm working on an iOS game, but I'm still learning and tinkering with new technologies.

For years I felt like an imposter for not rooting my smartphones, and not owning any raspbis. - Now finally I got an pi 4 and installed my so long desired pi-hole.

Quite disturbing that at least 30-40% of my traffic is known ad shit. Such an infestation.

Degree itself? Marginally useful. Learned most of what I know from youtube/CTFs/tinkering. Most kids graduating with me don't know or care what a rest service is, AWS. What's that?, Etc.

Is what you make out of it honestly.

Now the environment it provided and doors immediately opened by people I met/professors: invaluable. Guaranteed internships and jobs.

At work everybody uses Windows 10. We recently switched from Vagrant to Docker. It's bad enough I have to use Windows, it's even worse to use Docker for Windows. If God forbid, you're ever in this situation and have to choose, pick Vagrant. It's way better than whatever Docker is doing... So upon installing version 2.2.0.0 of Docker for Windows I found myself in the situation where my volumes would randomly unmount themselves and I was going crazy as to why my assets were not loading. I tried 'docker-compose restart' or 'down' and 'up -d', I went into Portainer to check and manually start containers and at some point it works again but it doesn't last long before it breaks. I checked my yml config and asked my colleagues to take a look. They also experience different problems but not like mine. There is nothing wrong with the configuration. I went to check their github page and I saw there were a lot of issues opened on the same subject, I also opened one. Its over a week and I found no solution to this problem. I tried installing an older version but it still didn't work. Also I think it might've bricked my computer as today when I turned on my PC I got greeted by a BSOD right at system start up... I tried startup repair, boot into safe mode, system restore, reset PC, nothing works anymore it just doesn't boots into windows... I had to use a live USB with Linux Mint to grab my work files. I was thinking that my SSD might have reached its EoL as it is kinda old but I didn't find any corrupt files, everything is still there. I can't help but point my finger at Docker since I did nothing with this machine except tinkering with Docker and trying to make it work as it should... When we used Vagrant it also had its problems but none were of this magnitude... And I can't really go back to Vagrant unless my team also does so...

So a co-worker of mine contacted me for help in her project. I was in no mood to help as I hadn't slept properly the previous day. But she begged me to help, so I obliged just so I could get her off my back and catch some rest after 2 hours, or at least that's what I thought it would be. But here I am, 10 hours later, having just finished helping her in her project, and now I have a really bad headache, just waiting to go to sleep, but my brain is betraying me.

It was a project that uses Tryton framework (based on Python), which I sometimes feel is fucking inconsistent. Things won't work as expected most of the time. Her boss (my ex-boss) is a piece of shit, and he wanted the work by the next day (i.e. today). And nobody else (not even the boss, who would have gotten this work done in less than half the time had he helped her even a little bit) was ready to help, because they all hate her for being a slow learner. All I had to do was get some data in a particular format in a text file using the framework. But the amount of tries it took just to get the data in the text files cost around 2 hours due to shitty internet speeds that caused tons of lag on Anydesk. Then we had to take breaks in between for reasons. But due to my agitated state of mind, I couldn't sleep in those breaks. Then I had to spend time tinkering around with ljust and rjust to get the right amount of padding for the data, which took hours due to shitty internet speeds that caused tons of lag on Anydesk. And then Tryton kept throwing errors in between which took some time to fix. But we finally completed half the task, and I am off to sleep.

As I write, my co-worker is still awake completing the work her boss gave her. It's around 1:46am IST. HER BOSS IS A PIECE OF SHIT.

Bought a new toy drone to play with at home, Ryze Yello. It boasts an Open SDK on the box and claims to be programmable. Awesome, I think, I end up buying and going home to get to work.

All is great using the app, I can fly the drone and the video feed is mostly usable. Now let's get in to the SDK and see what we have.

Docs say I've got a few basic commands, 8 directional flips, 6 directions of movement, rotate, takeoff, and land. Plus a config option to set the speed. After a bit of tinkering I discovered that only 3 commands actually work: takeoff, flip, land. The rest error out with no (currently) useful message.

A bit more searching online tells me that they borked the commands with a recent firmware update and are working on it as of 3 months ago.

I wish I knew more about firmware or deconstructing the wifi packets from the app so I could try to do something useful.

So many stupid things I wanted to do with an automated drone and I'm stuck waiting for them to fix their firmware to put functionality back into the device.

I love tinkering and i lowkey prefer chinese knockoffs to the original arduinos. I genuinely enjoy having to scout the internet for obscure drivers and sometimes having to write my own libraries.

So I gave my younger brother my OnePlus One since he is now using an even older Google Nexus and don't care much for phones. The camera is slightly better basically.

Asked him to test drive it:

Me: so did you set it up yet?
B: nope, what's the rush?
Me: well you see it's running a custom OS (Lineage) as it technically doesn't support it. You need to test drive it and make sure it works with your SIM? May need to change some configs
B: sounds like a pain, should I just get a new phone?

Me: ... yes probably...

He's a just graduated CS major that doesn't like tinkering with tech...

(Well can I have it back then so I can play around with it?)

Why is it such a hassle to get Android Studio to work? Spending several hours filled with with installs, reinstalls, downloads, googling, troubleshooting, more failures, suicidal thoughts, env variable tinkering, crashes, total apathy - before I can finally start writing some fucking code is fucked up.

Student 18/M looking for reliable partner.
I like tinkering, I like the command line and I find i3 convenient, but I also often just need to get things done, I want my os to be rock solid, and I would prefer debian based because I need to run lesser known/supported software occasionally.

Trying to install Linux on an HP Stream 7 has been way more difficult than it should have been, even when you take into account that it's a 32-bit processor with a 32-bit EFI!

First off, the only thing I've been able to get it to boot right of the bat is Android x86 and BlissOS... kind of. You would think that Android x86 would be perfect for a tablet, right? Nope, performance sucked sooooo bad.

After reading some forums, I was finally able to get Ubuntus to load up... with the limiting factor being no on-screen keyboard.

So... at the moment I guess I'm stuck with a useless Windows tablet, and probably will be for a long time (you know, since 32-bit architecture is being dropped)

!rant I need a TL:DR for custom ROMS, I already know what they are, what they do, I need to know how useful they are and where I can start!

Thanks!

Laziest habit? Anything done between 1pm-4:30pm and 4:59pm-8pm. During that time, habits include unnecessary refactoring, poking the CI/CD containers, editing already made prototypes in gimp inkscape, pasting stackoverflow topics to youtube, bouncing from macOS, windows and kde distros in search of zen/rice, adding a calendar emoji on my slack :), making useless automation scripts, building on every variable's value change, tinkering pixels, shades, gradients (and their angles), dimens, anim values, anim curves, opacity, blurs and just nuking the ui just to copy paste an old one, 60% just chatting in code alongs, changing key bindings (from ide to OS), and ultimately zoning out on a podcast about cyber security. And of course: waiting for ++ and comments

In last episode of "How SystemD screwed me over", we talked about Systemd's PrivateTMP and how it stopped me from generating SSL certificates.

In today's episode - SystemD vs CGroups!

Mister Pottering and his team apparently felt that CGroups are underused (As they can be quite difficult to set up), and so decided to integrate them into SystemD by default. As well as to provide a friendlier interface to control their values.

One can read about these interactions in the manual page "systemd.resource-control"

All is cool so far. So what happened to me today?

Imagine you did a major system release upgrade of a production server, previously tested on a standalone server. This upgrade doesn't only upgrade the distribution however, it also includes the switch from SysVInit to SystemD. Still, everything went smooth before, nothing to worry now then, right? Wrong.

The test server was never properly stress-tested. This would prove to be an issue.

When the upgrade finishes, it is 4 AM. I am happy to go to bed at last. At 6 AM, however, I am woken up again as the server's webservices are unavailable, and the machine is under 100% CPU load. Weird, I check htop and see that Apache now eats up all 32 virtual cores. So I restart it, casting it off to some weird bug or something as the load returns to normal.

2 hours later, however, the same situation occurs. This time, I scour all the logs I can, and find something weird - Many mentions that Apache couldn't create a worker thread? That's weird.

Several hours of research and tinkering later, I found out the following:
1 - By default, all processes of a system that runs SystemD are part of several CGroups. One of these CGroups is the PID CGroup, meant to stop a runaway process from exhausting all PIDs/TIDs of a system.

This limit is, by default, set to a certain amount of the total available PIDs. If a process exhausts this limit, it can no longer perform operations like fork().

So now, I know the how and why, but how should I solve this? The sanest option would be to get a rough estimate of just how many threads the Apache webserver might need. This option, though, is harder, than apparent. I cannot just take the MaxRequestsWorkers number... The instance has roughly double the amount of threads already. The cause being, as I found out, the HTTP/2 module, which spawns additional threads that do not count towards this limit. So I have no idea what limit to set.

Or I could... Disable the limit for just the webserver via the TasksAccounting switch. I thought this would work. And it did seem to... Until I ran out of TIDs again - Although systemctl status apache2.service no longer reported the number of tasks or a task limit of the process, the PID CGroup stayed set to the previous limit. Later I found out that I can only really disable the Task Accounting for all the units of a given slice and its parents.

This, though, systemctl somewhat didn't make apparent (And I skimmed the manual, that part was my fault)

So... The only remaining option I had was to... Just set the limit to infinite. And that worked, at last.

It took me several hours to debug this issue. And I once again feel like uninstalling systemd again, in favor of sysvinit.

What did I learn? RTFM, carefully, everything is important, it is not enough to read *half* the paragraph of a given configuration option...

Oh, and apache + http/2 = huge TID sink.

Finally managed to install nvidia driver on my ubuntu laptop after a couple of fucked up resulting in me formatting the ubuntu partition. Im sure there are solutions which didnt require reinstalling the OS but I gave up trying after wasting about hours tinkering with the installation, and restarting into blank screen.

Now that I can work and play dota on ubuntu, Im ready to get rid of the windows 10 dualboot

Me: *tinkering on a webpage that spits out random characters, motivations, themes, and genres for the purpose of short story creation*

Me: Okay, so we have a young girl, with the motivation of The Power of Friendship, the theme of Crime, with the story structure of Dan Harmon, and set in a Fantasy genre.

Coworker: Dan Harmon? Improvise. Wait... A young girl, on a Purge planet who befriends Morty... I mean a young boy from a different universe.

Me: *a minute later* Wait a second, that was an episode of Rick and Morty!!

Coworker: I did that on purpose because you said Dan Harmon.

Always want to try Linux as main OS, but troubles with audio stopped me. Have heard about new shiny pipewire, that solves all the linux audio mess.

It's pretty easy to setup, but audio with pipewire has crackled sometimes when recording. Spent half a day to fix it by following random guides and docs...

Now uninstall pipe and install jack. Just works fine: select device, change sample rate and you are ready without any fuckinf annoying crackles and tinkering with a lot of config options

I'm torn on dev bootcamps.

On one hand, I learn the most in hands-on direct tinkering and bootcamps tend to exude this with well-trained instructors following best practices.

On the other hand, the short timeline means corners are cut and an overwhelming amount of material is dropped all at once leading to a leaky retention vessel at the end.

I prefer ramping up learning over a period of time to gain experience than a fire hose approach.

To the SysAdmins and Linux-Engineers here,
How you got into your job?
I'm a Linux-Fanboy by heart and love tinkering and fiddling with systems, so I want to work in the field?
Please tell me, how you got into your job, and how it is to work in the field.

My first dev project was back in the 80's. I might have been around 10, I think.

My friend and I had been tinkering around Shoot'em up construction kit for a while, plus we'd been quite inspired by all the cracktros, intros and whatnot was popular back then (piracy was huge, at least on the C64 platform - I don't think I ever saw an original game until my parents bought an Amstrad CPC).

Anyway, we were inspired. We didn't know how to code except some basic BASIC (ba-dum-tsj). We borrowed a book from the library on how to code an assembler for the C64 in BASIC, and coded for days. I eventually lost interest, but my buddy did actually complete it.

Normally when I revisit an old project feel like tearing out my awful old code and rewriting it all - not today; today I feel like I am backsliding. I sidelined my personal project months ago when my real work got busy.

I have spent the evening discovering all the cool shit the project does and wondering if I'll ever get my head around it all again.

Looking forward to many nights tinkering and getting my memory back.

Received my first recruitment message on LinkedIn today. Generic as fuck "hey your profile looks nice, we have dis thing for you, come take a looksie".

Went ahead and read the whole thing, started laughing while reading requirements:
- own a degree in CS or related field: re-starting college next week
- extensive experience with automation processes: uuuh... I can write bash scripts and gulp tasks, how's that?
- extensive experience with Java, Angular, Selenium and Protractor: sure. Spent two weeks tinkering with those tools. Pretty much an expert already
- two years of experience: not even 6 months into my first job
And some other nonsense

Job would be in a very nice city, extended family lives nearby, actually a nice position. Too bad I am not looking for a job and my classes start on Monday 😂
But hey, at least people are looking at my profile! Yay!

So I've been tinkering with this idea since this morning:
There should be a dictionary for developers, to help give meaningful names for variables, functions.

With some pipe like interface to narrow down possible names,

Out of curiosity, is there anyone else who feels a bit late to the game in terms of their programming skills and training?

I got my start at about 10 with a slightly obscure BASIC dialect for classic MacOS, and while I got the logical bits down strong, I never really branched out too much at the time because I had difficulty understanding some of the more advanced examples I had available on my own.

Skip ahead to college and I tried CompSci my first semester, and did fairly well on paper, but could not get the compiler to work, even copying out known examples character for character and verifying them repeatedly. So after my first semester (and the hardest-earned D I’ve ever gotten) I ended up switching my major.

Skip another 10 years and I’m talking to some people about setting up a website, but the programmer flaked out on us, so I decided to start experimenting in PHP, and while that project never went anywhere I got good at developing resources for helping me keep my Japanese skills up (lots of logic/DB work, minimal interface).

Finally, after 10 more years of tinkering and during a bout of unemployment, I had a friend lament that he needed another programmer for his shop, but didn’t know anyone reliable. I apprenticed under him, learning WordPress along the way, and these days he’s moved on while I run the shop on my own, picking up new skills as needed.

There are times I feel absolutely confident in what I’m doing, but there are several areas where I feel like I’ve got a lot of fundamental gaps I can’t figure out how to address due to my near complete lack of formal training (like when I’ve tried to do non-web programming).

Anyone else have a similar path to where they are now? Ideas on how to break out of this limiting feeling?

I am mostly self-taught. If I am (really) interested in doing something new, or if I feel there is a need of doing something, I just do it. Simple.
Learnt a great deal by looking at others' codes (like how things are done, conventions etc), tinkering with the IDE, working on personal projects etc.

I spent a lot of my time as a little kid playing video games and typing on my old computer. Somehow I found GameMaker (6 or 7, I think) and started pumping out little games with the free version. I didn't like the drag and drop stuff so I learned GML (GameMaker Language).

A few years later someone gave me a PHP book and while I never actually learned anything from it, it did get me interested in learning a real programming language (not GML).

Around this time Minecraft became popular, and with a lot of YouTube videos I got a grasp on Java, and a little C++/C#.

Tinkering around in scripting languages finally lead me to JavaScript which of course introduced me to HTML and CSS.

I loved how quickly a website could me created compared to a compiled program, so I started spending most of my time learning Web Technologies.

And that leads me to where I am today. By this point I've spent over half of my life programing in various languages and formats and I've loved every bit of it!

I think I want to hop distro's.
Been using Manjaro xfce for like 6 months now. It's been really good(especially the AUR and software repos) but every now and then I found myself tinkering with weird probelms, especially when it comes to Nvidia drivers.

I need an easy to use, fire-and forget(auto hardware detection) distro with the newest software possible(I develop in Android and Node, and the most recent versions of IDE's and software are important.

I also don't want too much bloatware. I don't mind that much about customizability, as long as the default UI isn't ugly and hard to use.

Which diatro and DE you guys can recommend according to my preferences?

The sole reason for me not wanting to continue tinkering with the awesome features of Android SDK is Java.

I miss bug hunting... Baking new features is far less fun than debugging all sorts of weird issues across all the layers of the setup. Devops has its charm, but still I find myself looking for problems more often than tinkering with devtools.

I wish there was a "debugger" role in my company.

I have a small NUC-like machine in my home with an old external hdd connected to it. I use it to run my local gitlab, nextcloud and to test a few websites I build for the lolz.
If you too have a homelab, whether it's a single raspberry or an entire room full or racks, you know damn well that everything you have running locally as a web service keeps going until it doesn't, for whatever fucking reason. This time, it was the turn of my nextcloud.
The machine has arch linux running, I chose it since I already use it on my coding laptop and being a rolling release means I don't have to manually upgrade to a newer version, risking various fuck-ups and consequent screaming of profanity.
The downside is that arch is a bleeding-edge distro, so, despite being pretty good for what concerns security, as updates are pushed out some packages may still require legacy software to work as intended, since obviously not all developers for all packages can release simultaneously.
The problem was that php reached 8.2.x but nextcloud couldn't use anything beyond 8.1, so the highlighted solution was to download php-legacy, a package with a set of utilities which the cloud could use instead of mainline php.

Pretty easy, right? fuck my life, here we go.

I edited apache-httpd's configurations to link the new libraries, updated every reference in every virtual host that could possibly screw up the web server.

Done.

Then I went on and disabled the php-fpm mainline, creating a new systemd unit that would instead run the legacy executable and afterwards I edited nextcloud's additional configs so they use that instead.

Done, getting a bit dizzy, but I reboot everything and breathe.

At this point the migration should be complete, but wait, the server returns an error saying that the application is still trying to use php 8.2+...wait, what in the sysadmin Christ?

Back to nextcloud config, everything is set, everything else in every other fucking php-legacy and web server is fine, the old fpm service is disabled, I am confused, and why in the FUCKING FUCK is the new php-fpm unit failing to start at boot with "error 78/config - directory not found"? Hello? Am I being trolled by a shitty dual-core amazon fake NUC?
Maybe yes, cause it turns out that the unit was referencing a directory in the external hdd, which gets mounted at boot time after the unit itself starts, so nothing much, just a matter of tinkering with cron jobs, a reboot and at least this one is off my balls.

But why still isn't the server responding correctly? why? WHY?

After slamming my cock on the keyboard here and there scrolling back through all the config files I think to myself, hmmm, my gitlab is working flawlessly, well yeah, I didn't need to install the whole web stack, everything was nice and easy wrapped in a docker container...so why am I even here, why the fuck am I bothering with all this layered web-app bullshit, why don't I just run the up-to-date docker image that someone else has already set up for me, back up all the data and reupload them on the application?

Oh joy, you can't imagine, after 3...almost 4 hours of pure computer-touching the relief I had from seeing the blue web page with the "welcome to nextcloud" title.

Right now it's copying back all the files, and the external hdd is now linked to include the data folder.
Like really, everything was solved in two lines of bash.

I am still fuming, but at least I learned a valuable lesson, if you want a service up for yourself, implement it and deploy it as fucking easy straight-forward as you can, giving MAXIMUM priority to already fully-working options that are out there just waiting to be downloaded and used. I swing my scrotal sack on web-apps elegance as long as it's MY homelab in MY place.

Eat a fat dick php.

sudo pacman -Rns nextcloud
sudo systemctl disable --now php-fpm-legacy
sudo pacman -Rns php-legacy
sudo pacman -Rns $(sudo pacman -Qdtq)

I recently switched back from Android to using a BlackBerry Bold – a 9700, specifically. This transition was made because I have been growing increasingly impatient with the many, many flaws of Android, and iOS wouldn't work for me, even though it does work well for many people. There are many features of which I was unaware when I was using BlackBerry back in the day, such as general tinkering abilities; while I may not understand everything, I am smart enough to be able to use technical references to figure out most of that which I do not understand. I won't go into detail about this so I don't sound like an advertisement for a product which was abandoned by its own creator, but I thought that the people here might find the ability to fiddle with the device to be interesting.
Having an actual keyboard is pretty nice, too.

- Reading the docs and trying out examples (basically copy paste their example and try it in your computer)

- YouTube videos if I don't understand something from the docs. And to see how people explore various ideas I wouldn't have thought about

- From what I have learned, trying it by myself or applying it to somewhere useful

- Tinkering when free, else move on

Not a rant.

I’m tinkering for some months at something . Something that i want to turn into a startup, but i feel a little burned out, i have all this thoughts now that’s a shit idea that no one would even want it , even though i had great feedback and some users are already using it.

How do you guys deal with things like this?

Finally got Proton to run arbitrary programs with some tinkering. Works fairly well for running nigh anything I throw at it, even some random non-game programs. Might do this more often. (Next up: DXVK)

Started working with AWS API Gateway and needed to process some data coming in from an it via AWS Lambda.

After much tinkering with the API Gateway, realised that no matter what I do, the response body of the API Gateway will be a string literal and not a JSON.

Why does this have to be this way? Half a day lost banging the head against the wall.

!= rant

Does AngularJS still have momentum. I toyed with it for a while on a side project. Since then .Net Core launched and most of my work (both day to day and side projects has been in MVC 5 or .Net Core)

I wanted to go back to tinkering with that one side project but it seems that some of the hype surrounding AngularJS has died off.

Hi there, my 2 cents to rant on WWDC :)

- Check time? My big head is in the way.
- Work tabs... Why is my Wordle in the list?
- Edit message ... Good bye iMessage memes :(
- Dictation. Hello Jarvis. Hi CIA. Sup 0-day devs
- Live Text. Indian tutorials are now just a copy paste away
- Wallet keys sharing through messages 🤌
- Family. Send more screen time through messages (goodness this messaging app is becoming less green)
- Shared libraries in photos, lovely, now your aunt knows you love visit and taking photos of the neighbor (if you forget to turn it off)
- CarPlay, this will need screen time soon, ui so beautiful you gonna plan a journey by tinkering with the dials
- Check time (part 2) on the iwatch, My big head is still in the way
- Fitness app, Sleep app, Health app, Medication app, mmm lovely but still cant put my confidence in AI
- M2, saw it coming. Spec: scaringly powerful.
- isnt the midnight MacBook air elite?! But the notch tho. Magsafe is back, more thin, this thing looks fragile.
- Did they show a game running lower than the videos fps on purpose? Hmmm
- Ventura's stage manager, xbmc vibes
- Is that Facetime attachment free? Is there a subscription to continuity camera?
- Tab Group Collaboration, hehe, "they can see which tabs you're looking at" hehehe
- Free Form: bloatware

Meh, I cant rant more, honestly the new features look good.

I'm needing an idea for a new project. I began tinkering with one of my old C# projects and I'm just **disgusted** with the amount of crap in there.

What do you guys think, should I finish it or move on?

Any good ideas on how to find another idea for a new project?

today I will have the last of my high school finals.
I feel like after today I will be a free boy (for three months, at least). Like I have won the game, beaten the boss level.
After 7 years of resisting to comply to this system which tries so hard to shape every pupil into a compliant individual, it will be done.
My creativity and productivity (which lies in tech, which isn't really represented in any subject in my school), set free.
No more mandatory pseudo-interest in loads of literature and cultural history. The bits that are interesting would have come to me anyways through Reddit.

Victory is mine. YAY \o/
World, here I come!

P.S. yes, of course, there were also positive things. I'm actually thankful for that time I failed the year's end exam about literature which ended in me having to redo that year. It landed me with loads of free time, which got me into tech-tinkering, a now two-year employment as a programmer, and a juniar participation at the nearest Hackerspace. And a chance to pretty much build and operate a 3D-printer, for which the physics department mostly covered the cost. The school unknowingly gave me the opportunity to extend my own horizon outside of school, and it brought me so much nice things. :) But the mandatory interest in literature and cultural/religious history and the lack of technical subjects and the digital oppression still sucked.

P.P.S. oops that was only supposed to be a short P.S.

A change of pace in these weird and wonky times!

Been a good quarantine so far!
I've been working steadily on a few side projects, and I'm quite proud of myself, that I'm actually "working", instead of TODOing them.

Tinkering with a chrome extension, making considerable progress on my personal website, being more mindful, establish a proper routine and started a new project with a friend!

Fuck you, linux modules!! I know tinkering with you was going to be dangerous, but I've already spent 4 hours just rebuilding virtual machines from every screwup.

I personally love the architecture of Linux, it tickles my fancy and it's super elegant... But fuck you!

Just found out about HookTube and Mastodon (I'm @digitaldina) and I was wondering if anyone else knows some good Dev/security related apps/sites that are useful? Also, I'm tinkering with app dev now and I'm wondering if any of you would recommend starting out using Firebase? Is it any good?

Please let me know in the comments I'd love to find out :)

Hey guys ! I want to start some kind of blog so I can share my experiences and tinkering with stuff.
I can't seem to find a good CMS for that ? I've no problem with coding the blog myself (with Rails preferably), but I'd like to not start from scratch ! I'll need handle syntax coloration for code samples for example.
Any advices, ready-to-use stuff or not ? :)

Hi everyone

I have a pretty old sansui tv in my room that I lost the remote for ages ago. I would like to remotely control the TV without having to buy the actual remote for the specific model (which is ~$28). Any ideas on how I can find the remote codes for the tv so I can program my own remote? Let me know if u guys have any ideas, thanks!!

The job is supposed to be about tinkering with and determining what tech to pull together and how to make it work best to solve novel problems. Not to roll back the code and get fast doing the same fucking project

So, despite being pretty experienced with Linux server management, today, I failed, even after hours spent tinkering, to get Bumblebee working on an older laptop of mine (Intel i3 + Geforce 960m).

What's funnier is that before I wiped that laptop with a clean install, it was working, albeit it on an out of date kernel / driver combo.

Though curiously, despite using the newest release of Xubuntu, the Bumblebee PPA repo wasn't signed (Missing InRelease file), and further lacked one of the Package index files (For i386 i believe)

I'm about to sell the laptop tomorrow. Anyone has any hints or things I could have missed? I still have a day to work on it, and if I don't manage, I'll just put on a clean win install...
