This rant is particularly directed at web designers, front-end developers. If you match that, please do take a few minutes to read it, and read it once again.
Web 2.0. It's something that I hate. Particularly because the directive amongst webdesigners seems to be "client has plenty of resources anyway, and if they don't, they'll buy more anyway". I'd like to debunk that with an analogy that I've been thinking about for a while.
I've got one server in my home, with 8GB of RAM, 4 cores and ~4TB of storage. On it I'm running Proxmox, which is currently using about 4GB of RAM for about a dozen VM's and LXC containers. The VM's take the most RAM by far, while the LXC's are just glorified chroots (which nonetheless I find very intriguing due to their ability to run unprivileged). Average LXC takes just 60MB RAM, the amount for an init, the shell and the service(s) running in this LXC. Just like a chroot, but better.
On that host I expect to be able to run about 20-30 guests at this rate. On 4 cores and 8GB RAM. More extensive migration to LXC will improve this number over time. However, I'd like to go further. Once I've been able to build a Linux which was just a kernel and busybox, backed by the musl C library. The thing consumed only 13MB of RAM, which was a VM with its whole 13MB of RAM consumption being dedicated entirely to the kernel. I could probably optimize it further with modularization, but at the time I didn't due to its experimental nature. On a chroot, the kernel of the host is used, meaning that said setup in a chroot would border near the kB's of RAM consumption. The busybox shell would be its most important RAM consumer, which is negligible.
I don't want to settle with 20-30 VM's. I want to settle with hundreds or even thousands of LXC's on 8GB of RAM, as I've seen first-hand with my own builds that it's possible. That's something that's very important in webdesign. Browsers aren't all that different. More often than not, your website will share its resources with about 50-100 other tabs, because users forget to close their old tabs, are power users, looking things up on Stack Overflow, or whatever. Therefore that 8GB of RAM now reduces itself to about 80MB only. And then you've got modern web browsers which allocate their own process for each tab (at a certain amount, it seems to be limited at about 20-30 processes, but still).. and all of its memory required to render yours is duplicated into your designated 80MB. Let's say that 10MB is available for the website at most. This is a very liberal amount for a webserver to deal with per request, so let's stick with that, although in reality it'd probably be less.
10MB, the available RAM for the website you're trying to show. Of course, the total RAM of the user is comparatively huge, but your own chunk is much smaller than that. Optimization is key. Does your website really need that amount? In third-world countries where the internet bandwidth is still in the order of kB/s, 10MB is *very* liberal. Back in 2014 when I got into technology and webdesign, there was this rule of thumb that 7 seconds is usually when visitors click away. That'd translate into.. let's say, 10kB/s for third-world countries? 7 seconds makes that 70kB of available network bandwidth.
Web 2.0, taking 30+ seconds to load a web page, even on a broadband connection? Totally ridiculous. Make your website as fast as it can be, after all you're playing along with 50-100 other tabs. The faster, the better. The more lightweight, the better. If at all possible, please pursue this goal and make the Web a better place. Efficiency matters.8
Does someone happen to know a book that goes deep in C, like really deep ?

Actually clears the terminal instead of just scrolling down like clear.1
The amount of people who don't know the difference between kilobyte and kibibyte is too damn high. So much confusion.
TL;DR : Most people use Kilobyte ( KB ) and Kibibyte ( KiB ) wrong and i am angry about it.
When i first got involved with software as a teenager, i always wondered why we convert kilo to mega with multiplying by 1024, when we do it with multiplying by 1000 basically everywhere else. Our physics teacher called this SI unit system and told us that this is an internationally accepted statement. So why is there a different rule ? Did i miss out something ? Regrettably I didn't ask her about this.
I just didn't get fully as a teenager. Now, as I am a developer now, i understand that dealing with power or ten is troublesome. Due to ease of work, we lazily mess with SI system and use it wrongly. Isn't it the time we end this abomination ?
2 years ago i talked to a friend about this, he said that i shouldn't bother.
I talked to a teacher, he said "you are right but using different brand of unit system can be overkill, since there is not much difference anyways." I said okay and left.
1 mega = 1000 kilo
1 giga = 1000 mega etc
MB = Megabyte ( 1000 Kilobyte )
KB = Kilobyte ( 1000 Byte )
MiB = Mebibyte ( 1024 Kibibyte )
KiB = Kibibyte ( 1024 Byte )
I am writing this because today i saw someone do it wrong on the internet, all of these came into mind. I wonder your approach about this, for research purposes.
Call me dick all you want, but i am the guy who always corrects uncertainty, no matter what. Things should be in place, correctly. No i don't have OCD. If you say something like "I have 1 MB of executable file, which means i have 1024 KB of it", i will find you, and i will correct you.37
You're fucking using a PC.
If you're using an apple product that is a computer (it fucking computes things) and you can use it on your own then it is a personal computer. That's what PC means for the love of #keepDevrantReligionFree
I just saw someone saying that they use neither: Mac nor PC
Upon asking for clarification they said that they are using arch.
Are you fucking kidding me? Do you want to be as "cool" as Apple and refuse to use a name that's used for those kind of devices just to not belong in the same group as others?19
“404” jokes are the equivalent of “what’s brown and sticky? A stick”.
Show some creativity, numbskull.10
Am I the only one who procrastinates only on starting a task? Like, once I start the task, then it's easy to keep going till completion; but I can't freaking get my butt into the chair and start.
Any tips on how to get over starting troubles?7
Why is there so many memes in this forum? Dude this is about ranting and cursing about stupidity, ignorance or about some bullshit. If I want to see CS memes i go to reddit. This has to stop
I have noticed on here, there is a direct correlation between the number of swear words in a post and that posts ++ count. As a programmer who doesn't swear (I know, "just give it a few years" or "YOUR NOT A REAL PROGRAMMER!!" [side note, I also don't drink coffee]), I guess my ++ counter will only ever be allocated 1 byte...13
I need to rant about life decisions, and choosing a dev career probably too early. Not extremely development related, but it's the life of a developer.
TL;DR: I tried a new thing and that thing is now my thing. The new thing is way more work than my old thing but way more rewarding & exciting. Try new things.
I taught myself to program when I was a kid (11 or 12 years old), and since then I have always been absolutely sure that I wanted to be a games programmer. I took classes in high school and college with that aim, and chose a games programming degree. Everything was so simple, nail the degree, get a job programming something, and take the first games job that I could and go from there.
I have always had random side hobbies that I liked to teach myself, just like programming. And in uni I decided that I wanted to learn another language (natural, not programming) because growing up in England meant that I only learned English and was rarely exposed to anything else. The idea of knowing another fascinated me.
So I dabbled in a few different languages, tried to find a culture that seemed to fit my style and attitude to life and others, and eventually found myself learning Korean. That quickly became something I was doing every single day, and I decided I needed to go to Korea and see what life there could be like.
I found out that my university offered a free summer school program for a couple of weeks, all I had to pay for was the flights. So a few months later I was there and it was literally the best thing I'd done in my life to that point. I'd found two things that made me feel even better than the idea of becoming the games programmer I'd always wanted to be. Travelling and using my other language to communicate with people that I couldn't in English. At that point I was still just a beginner, but even the simple conversations with people who couldn't speak English felt awesome.
So when I returned home, I found that that trip had completely thrown a spanner into my life plan. All I could think about after that was improving my language skills and going back there for as long as possible. Who knows what to do.
I did exactly that. I studied harder than I'd ever studied for anything and left the next year to go and study in Korea, now with intermediate language skills, everyday conversations no longer being a problem at all.
Now I live here, I will be here for the next year and I have to return to England for one year to finish my degree. Then instead of having my simple plan of becoming a developer, I can think of nothing I want to do less than just stay in England doing the same job every day, nothing to do with language. I need to be at least travelling to Korea, and using my language skills in at least some way.
The current WIP plan is to take intensive language classes here (from next week, every single weekday), build awesome dev side projects and contribute to open source stuff. Then try to build a life of freelance translation/interpreting/language teaching and software development (maybe here, maybe Korea).
So the point of this rant is that before, I had a solid plan. Now I am sat in my bed in Korea writing this, thinking about how I have almost no idea how I'm going to build the life that I want. And yet somehow, the uncertainty makes this so much more exciting and fulfilling. There's a lot more worrying, planning and deciding to do. But I think the fact that I completely changed my life goals just through a small decision one day to satisfy a curiosity is a huge life lesson for me. And maybe reading this will help other people decide to just try doing something different for once, and see if your life plan holds up.
If it does, never stop trying new things. If it doesn't (like mine), then you now know that you've found something that you love as much as or even more that your plan before. Something that you might have lived your whole life never finding.
I don't expect many people to read this all, but writing it here has been very cathartic for me, and it's still a rant because now I have so much more work and planning to do. But it's the good kind of work.
Things aren't so simple now, but they're way more worth it.3
Headphones are in, colleague calls my name, I take them out a little annoyed at the interruption.
Colleague: what did one window say to the other?
Me: you're such a pane you know that?
Colleague: no but fuck! That's better1
One of my python students just uses his index fingers to type. And he moves his hands from elbows for each key. He said he completed his post graduation. I don't know how he survived these many years. I advised him to learn touch typing though.2

I'm not a web dev, but I have dabbled.
Discovered CSS grid this week. Really like it. Seems like finally there is some CSS syntax that works with devs rather than fighting with them.
FUCK this startup mentality of implementing all these external services and APIs for absolutely fucking everything.
I get that your vacuous fresh-mint-tea-soaked hipster brains are all cheering about these "only $10/month/seat" services, because you imbeciles with your nodejs-sticker-plastered macbooks have never done anything but knot the work of other dimwits together.
I don't even care about the subscription costs. That shit is more trouble to maintain than writing it yourself, and there's no guarantee that visualizemyballs.com & lintmycock.io still work tomorrow.
I'm getting so sick of being barraged with 502 bad gateway errors because you halfassed yet another API implementation. Stop advertising your crossfit stats, your meditation-app records and your vegan protein bars for a minute, and maybe start writing some fucking code of your own, something with a higher shelf-life than your iPhone screen...
You know... something which actually fucking adds value to the world.16
