curl cheat.sh — get an instant answer to any question on (almost) any programming language from the command line
tldr
do curl cht.sh/go/execute+external+program to see how to execute external program in go
And this question: why I actually should I start the browser, and the browser has to downloads tons of JS, CSS and HTML, render them thereafter, only to show me some small output,
some small text, number or even some plot. Why can't I do a trivial query from the command line
and instantly get what I want?
I decided to create some service that will work as I think such a service should work.
And that is how wttr.in was created.
Nowadays you probably know, how to check the weather from the command line, but if not:
curl wttr.in
or
curl wttr.in/Paris
(curl wetter in Paris if you want to know the weather in Paris)
After that several other services were created (the point was to check how good the console
can solve the task, so I tried to create services providing information
of various nature: text, numbers, plots, pseudo graphic etc.):
curl rate.sx/btc # to check exchange rate of any (crypto)currency
curl qrenco.de/google.com # to QRenco.de any text
And now last but not least, the gem in this collection: cheat.sh.
The original idea behind the service was just to deliver a various UNIX/Linux command line cheat sheets via curl. There are several beautiful community driven cheat sheet repositories such as tldr, but the problem is that to use them you have to install them first, and it is quite often that you have no time for it, you just want to quickly check some cheat sheet.
With cheat.sh you don't need to install anything, just do:
curl cheat.sh/tar (or whatever)
you will get a cheat sheet for this command (if such cheat sheet exists inf one of the most popular community-driven cheat sheet repositories; but it surely does).
But then I thought: why actually show only existing cheat sheets? Why not generate cheat sheets or better to say on the fly? And that is how the next major update of cheat.sh was created.
Now you can simply do:
curl cht.sh/python/copy+files
curl cht.sh/go/execute+external+program
curl cht.sh/js/async+file+read
or even
curl cht.sh/python/копировать+файл
curl cht.sh/ruby/Datei+löschen
curl cht.sh/lua/复制文件
and get your question answered
(cht.sh is an alias for cheat.sh).
And it does not matter what language have you used to ask the question. To be short, all pairs (human language => programming language) are supported.
One very important major advantage of console oriented interfaces is that they are easily
programmable and can be easily integrated with various systems.
For example, Vim and Emacs plugins were created by means of that you can
query the service directly from the editor so that you can just write your
questions in the buffer and convert them in code with a keystroke.
The service is of course far from the perfection,
there are plenty of things to be fixed and to be implemented,
but now you can see its contours and see the contours of this approach,
console oriented services.
The service (as well as the other mentioned above services) is opensource, its code is available here:
https://github.com/chubin/cheat.sh
What do you think about this service?
What do you think about this approach?
Have you already heard about these services before?
Have you used them?
If yes, what do you like about them and what are you missing?

I'm a week into my new job right now. What do I love the most about it?
Learning things all day long and getting paid for it!
I'm learning about hosting things, DNS, cyber security, configurations, Linux (although my current skill set with Linux has been enough for now) and so on!
Hell, easy day today (not that many tickets) so decided to start learning Ansible! Next to that I've gotta learn vim (it just autocorrected that to cum.... O.o), work with hosting panels, mail stuffs (dns, debugging etc etc) and so fucking on.
The boss hasn't been at location yet which will happen tomorrow but he seemed like a very chill guy.
I love this!21 -
Someone saw that i didn't use mouse while typing code and asked me how do i do that and i told him that i just use vim. He didn't know what it is and i told him some things that it has a learning curve and stuff and he told me that he will definetely look into it.
Come to the dark side kid.5 -
I hate that trend of making things more lax in terms of implementation quality while writing it off with a simple but stupid "oh computers are faster now, users have the RAM, yadda yadda". Yeah but back in a day things were actually running pretty damn fast in comparison while doing it on hardware that is totally potato in comparison to what's used now. This trend eats away ANY gains we get in terms of performance with upgrades. It deprecated the whole notion of netbooks (and I kinda liked them for casual stuff), since now every goddamn one-page blog costs you from several megabytes and up to tens of megabytes of JS alone and lots of unnecessary computations. Like dude, you've brought in a whole Angular to render some text and three buttons, and now your crappy blog is chewing on 500 MB of my RAM for whatever reason.
Also, Electron apps. Hate them. Whoever invented the concept, deserves their own warm spot in Hell. You're doing the same you would've done more efficiently in Qt or whatever there is. Qt actually takes care of a lot of stuff for you, so it doesn't look like you'll be slowed down by choosing it over Electron. Like yeah, web version will share some code with your desktop solution but you're the whole reason I'm considering your competitor's lack of Electron a huge advantage over you even if they lack in features.
Same can be said pretty much about everything that tries to be more than it should, really. IDEs, for example, are cancerous. You can do 90%+ of what you intended to do in IDE using plain Vim with *zero* plugins, and it will also result in less strain on your hands.
People have just unlearned the concept of conscious consumption, it seems.28 -
@JoshBent and @nikola1402 requested a tutorial for installing i3wm in a windows subsystem for linux. Here it is. I have to say though, I'm no expert in windows nor linux, and all I'm going to put here is the result of duckduck searches, reddit and documentation. As you will see, it isn't very difficult.
First things first: Install WSL. It's easy and there's a ton of good tutorials on this. I think I used this one: https://msdn.microsoft.com/en-us/...
Once you got it installed, I guess it would be better to run "sudo apt-get update" to make sure we don't encounter many problems.
Install a windows X server: X is what handles the graphical interface in linux, and it works with the client/server paradigm. So what we'll do with this is provide the linux client we want to use (in this case i3wm) with an X server for it on windows. I guess any X server will do the work, but I highly recommend vcXsrv. You can download it here:
https://sourceforge.net/projects/...
for i3 just "sudo apt-get install i3"
Configurations to make stuff work:
open your ~/.bashrc file ("nano ~/.bashrc" vim is cool too). You'll have to add the following lines to the end of it:
"""
export DISPLAY=:0.0 #This display variable points to the windows X server for our linux clients to use it.
export XDG_RUNTIME_DIR=$HOME/xdg #This is a temporary directory X will use
export RUNLEVEL=3
sudo mkdir /var/run/dbus #part of the dbus fix
sudo dbus-daemon --config-file=/usr/share/dbus-1/system.conf #part of the dbus fix
"""
Ok so after this we'll have a functional x client/server configuration. You'll just have to install your desktop enviroment of choice. I only installed i3wm, but I've seen unity and xfce working on the WSL too. There are still some files that X will miss though.
*** Here we'll add some files X would miss and :
With "nano ~/.xinitrc" edit the xinitrc to your liking. I only added this:
"""
#!/usr/bin/env bash
exec i3
"""
Then run "sudo chmod +x ~/.xinitrc" to make it an excecutable.
Then, to make a linking file named xsession, run:
"ln -s ~/.xinitrc ~/.xsession"
Now you'll be able to run whatever you put in ~/.xinirc with:
"dbus-launch --exit-with-session ~/.xsession"
There's a ton of personalisation to be done, but that would be a whole new tutorial. I'll just share a github repo with my dotfiles so you can see them here:
https://github.com/DanielVZ96/...
SHIT I ALMOST FORGOT:
Everytime you open any graphical interface you'll need to have the x server running. With vcXsrv, you can use X launch. Choose the options with no othe programs running on the X server. I recommend using "one window without title bar".10 -
Depends. No one took for the job. VSCode is really good for web and Python. I use Visual Studio for c#, c++ and c. Jetbrains for Java stuff, including Android studio.
When writing SQL I usually use vendor-provided editors like MySQL Workbench. They're the tool made for the job.
Visual Studio Code is my generic editor thanks to it's easy-access terminal. Makes running anything a breeze.
It doesn't feel as snappy as other editors though and installing plugins just for intellisense to work can be annoying, which is why I use other tools for other workflows.
Generally, I avoid things like vim. Sorry, but I have a mouse AND a keyboard. Paid for em both, and I intend to use em. Sometimes I wanna find a setting in a menu and not fuck around with config files after googling what the right setting is called.
I used Sublime for a while, but never really got too into it. It's okay.1 -
The Sorry State of Web programming (and who should be punished for it)
"And if you’re really lucky, and your following grows to scientology-levels of fanaticism you may get your own con. Yes con. Like DockerCon, or JsCon, or LongConJs, because thats exactly what all this is — and it’s exactly what we need: more excuses to meet up for the already sterile pollination of bedfellows, the unwashed, unvarnished masses of guys in their 30s, obsessively stroking their perfectly manicured beards and arguing over the comparative differences between vim versus emacs while completely oblivious about things like how you’re supposed to wear an undershirt with your button up. If not for hackathons, and ted talks, and sxsw, and conferences, and SomethingCons, and ‘retreats’, and dozens of other pointless synonyms for ‘people just meeting up’, most of us would still be in our cubicle, office, or room, typing away instead of socializing like normal people."
Full post here because I like to insert pictures because like all normie fucking simpletons I like pictures in my books.

I was pressing 'j' in vim and it was typing 'j' onto the screen and i was like what the fuck, why is typing j inserting a j into my file. Realised i was accidentally in insert mode.

Ok so some of you have probably seen my previous rants about my computer science teacher and our project but I'm just going to summarize all of them and share with you more of my pain.
1. He edits in the production environment. Its a laravel project and he is creating test database migrations IN THE PRODUCTION ENVIRONMENT AND SWITCHING BACK AND FORTH FROM MASTER AND DEV.
2. He edits in vim and doesn't follow codestyle even though I printed him off a piece of paper and emailed it to him.
3. He doesn't have any ethic when it comes to more complex things like laravel homestead.
4. He doesnt want me to release features even though he takes really long to do them.
While I love vim and it is my editor of choice, some things should be done in an ide. This is really annoying me and I'm really just considering handing him the project if he can't follow basic outline.6 -
Pressing ESC at the end of the line so that the modal in the browser closes and I have to write everything again.
Just Vim things1 -
So this happened a few days ago
I was working on a module assigned by my senior, and was the sole developer on that module. Just when I was breaking my head to get a bash script correct (was writing a bash script for first time), my senior comes and looks at my messy script and goes "No, no, no, no that's not how you do it. "
Takes the keyboard and starts editing my script opened in vim.
Did some cool restructuring, taught me a few things about bash and while talking to me kept the keyboard back at its place.
I keep my hands on keyboard while talking to him and press
[Escape] :q!
And as I pressed Enter my face went purple/blue thinking this is not good. 😨
(I have a habit to quit as I had almost never edited and saved a vim file before)
And he sees that face and says
what happened?
No nothing. Everything's cool.2 -
Is there something you find genuinely cool and would recommend ? Some webpage, program, OS, library or anything ?
I mean hey. There are SO MANY reaaaally cool things I didn't know until last few months.. Things I'd be so grateful for if I knew them earlier. I'll list some of them and I just know you have few of yours too. Feel free to educate the rest!

Last thing, if nothing, just check the websites on GitHub, that's lifechanger
Looking forward to see some cool links & recommendations!2 -
So here I work with this colleague that , at first , had a reasonable résumé. Whatever.
Time goed by and he is just doing tickets, clicking left and right, the usual grind of a shitty monitoring system which I am working intensely on deprecating that shit. Anyhoo
The last few days it became apparent that his resume was basically a hot air cake and he knows basically nothing intrinsically.
As I have stated before in previous rants, "everyone was a noob once"... But this guy...
He wants to do "something with Ansible"... "Ok what do you want to do?" , I asked (and I regret to have asked).
He basically wants to write new files on targets. Easy enough, I show him how he could do it with playbooks, inventory and role just for demonstrating the entire chain.
This guy chanes everything up, thereby breaking host group assignment, he launchea it on ALL machines...
Luckily it's a harmless file, so dodged a bullet there.
But the real wtf ia that he did it with the root account for our systems, without understanding the difference between "authentication" and "authorization"...
I am now explaining him what the difference is and how he can be able to check it. I give him the commands literally! ( sudo -l -U <user>)
Manages to fucking open up each sudoer file in vim , mistype or whatever he did in an attempt to leave vim... Breaks sudo...
Now he tries to spin it in such a way that I have steered him to break things.
"Dude you just fucking failed a copy/paste and you did absolutely fuckall without understanding what you are doing, then splurge out accusations because you did it wrong!"

Things that piss me the fuck off about user programs(in this case text editors):
No fucking documentation or signs of it available, a promise from like 3 years ago to post: tutorials/actual docs and yet unfulfilled shit. Yet the author sells the editor, you can get a free version of it, but the extension api is only given in the paid version. It's like $12 bucks, which depending on where you are from is really the cost of a meal.
The editor in question is 4coder, seems like a good stack for building C/C++ based applications with a lot of cool utilities underneath, I see dudes using it to create a lot of cool shit online, but things like moving input, stopping the thing from formatting pasted code etc etc. Shit, even reaching the documentation is fucky, you get the names of the commands......ok...awesome...wtf do I do with these? Why do i need to watch a 20+ minute tutorial from the developer instead of being able to read a retarded ass tutorial regarding how to do the most basic shit? For an editor that is set to replace Emacs and Vim for developers inside of a windows platform....it sure is lacking AF in that regards.
I really want to work with this thing because it seems to be made with a lot of heart, just can't stand the fact that the documentation is lacking like a motherfucker4 -
In today's edition of "things that I don't see the point of", I've been looking at Obsidian today, after hearing more than one person say that it's great for note taking. I use IA Writer sometimes, and I enjoy it, and I was kind of expecting something similar, but more geared toward notes and development type stuff. There are some nice graph-visual type things, and the ability to hyperlink notes together. It seems nice.
So after using it for an hour, I have to wonder why I wouldn't just make a private git repo full of .md files, and save myself four bucks per month? I get my "private vault", vim keybinds, and all of that good stuff without getting another application. Not trying to shit all over obsidian, I know it has fans, but am I missing something?5 -
It's always a matter of much is there to do and in what language...
There is the IDE-Zone, which is dominated by IntelliJ (CLion be praised when you do Rust or C++) for large stuff and heavy refactorings.
Always disputted by VS Code with synced settings. It's nice and comfy and has every imaginable language supported good enough, especially when its smaller change in native code or web/scripting stuff.
Then there is the "small changes" space, where Vim and VS Code struggle whos faster or which way sticks better in my brain...
might be you SCP stuff down from a box and edit it to re-upload, or you use the ever-present vi (no "m" unfortunately)
sometimes things are more easy for multi-caret editing (Ctrl-D or Alt-J), and sometimes you just want to ":%s/foo/bar/g" in vim.
I am sure that each of these things are perfectly possible in each of the editors, but there is just reflexes in my editor choices.
I try to stay flexible and discover strenghts of each one of my weapon of choice and did change the favorites. (Atom, Brackets, Eclipse, Netbeans, ...)
However there are some things I tried often and they are simply not working for me...
might for you. I don't care. and I'll just use some space to piss people off, because this is supposed to be a rant:
nano just feels wrong, emacs is pestilence from satan that was meant for tentacles instead of fingers, sublime does cost money but should not, gives me a constant guilty feeling (and I don't like that) that, and all the editors from various desktop environments are wasted developer ressources.
