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?

Who the fuck at Microsoft decided to put python on their store? I don’t care if it’s on the store. What I do give many shits about is that I spent 20 minutes uninstalling and reinstalling and reconfiguring my fucking PATH because the python & python3 commands did not work but instead SENT ME TO THE FUCKING STORE PAGE FOR PYTHON 3.7
THEN I FIND OUT ITS NOT A PROBLEM WITH THE PATH MICROSOFT PURPOSELY CREATED ALIASES FOR BOTH COMMANDS SO THEY HAVE TO SEND YOU TO THE STORE PAGE WHEN YOU TYPE python OR python3 INTO THE CMD OR POWERSHELL.
I turned it off after finding that out, but I’m still furious. Fuck Windows.22 -
Enough is enough! I can't do it anymore!

alias pm='python manage.py'
alias ga='git add .'

alias gi='git init && touch .gitignore && printf ".idea \n venv \n node_modules \n out \n *.iml \n *.log \n build \n target" > .gitignore'

Much better :D12 -
Today's rant: JavaScript's type system.
I realized halfway through that I can't happily call JavaScript a "programming language" so just assume
alias programming="scripting"
I'm sure it's not actually as frustrating as it seems to me. Thing is, I'm used to either statically-typed languages or dynamically-typed languages that actually make sense. If I were to try to add an integer to something I'd forgotten was a string in Python, it'd immediately tell me "look, buddy, do you want me to treat this as a concatenation or an addition? I have no idea the way you've got this written." I've found that mistakes are a common thing with dynamic typing. Maybe I'm just not experienced enough yet, maybe it's really as stupid as it looks. JavaScript just goes "hey look I'm gonna tack all of these guys together and make a weird franken-string like '$NaN34.$&' because that's absolutely what we want here!" Then I run my webpage and instead of a nice numeric total like I wanted, good old JavaScript just went "Yep, I have no idea what I'm doing here I'm just gonna drop this here and pretend it's right." Now absolutely I do not expect my programming language to make correct assumptions and read my mind, otherwise JavaScript would be programming me and not the other way around. But it could at least let me know that I had incompatible types going on rather than just shamelessly going along with what it's doing. Good GRIEF, man, some of the idiosyncrasies of the EMCAScript language definition itself just make me want to punch a horse.6 -
Be developing in python 3
$ pip install <library>
Don't understand for hours why it doesn't work
I should alias pip3 -
Installation instruction for a program written in Python:
> pip install MyProgram
Ok but I do not have pip, so I install it... Oops, needs Python 3 but linux has Python 2 installed by default. I try to start the program; it crashes.,...
People using Python, are you serious??????????? 👏👏😳 So it is possible to install a program written in Python only if I f*ck around with Python versions? I have both 2 and 3 installed but how the hell do I know what version is used when I run pip? I set global alias python=python3 but it did not help. RIP.8 -
!something annoying
I've always had this in the back of my head, and off lately it's eating me alive.
Why don't we just rename python3 to python and Python to python2?
no I'm not gonna alias it in my shell. I'm talking about renaming them in all the distros.
there've been talks about renaming python3 to python and marking it as the default for quite long, but nothing has come of it yet.
I get that a lot of shit is gonna go down if this happens rn, systems breaking, migrations, panic, a lot of systems still working on python2 but we need to migrate.
we've also been hearing a lot of speculation about "Python 4", from earlier this year.
WHAT IS HAPPENING UGHHHH
pls revolution now7
