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

Projects management in a nutshell

Question for vim veterans:

I am fairly confident with vim. I know a couple of commands like delete line, delete under cursor, copy, paste, undo and stuff like that.

So in command mode it's hjkl to move the cursor, which is a good idea because I won't have to move my right palm to the arrow keys.

However, in insert mode, if I needed to move the cursor, I would still have to move my left palm to the esc key in order to use hjkl. Why not just use the arrow keys then?

A super creepy webcrawler I built with a friend in Haskell. It uses social media, various reverse image searches from images and strategically picked video/gif frames, image EXIF data, user names, location data, etc to cross reference everything there is to know about someone. It builds weighted graphs in a database over time, trying to verify information through multiple pathways — although most searches are completed in seconds.

I originally built it for two reasons: Manager walks into the office for a meeting, and during the meeting I could ask him how his ski holiday with his wife and kids was, or casually mention how much I would like to learn his favorite hobby.

The other reason was porn of course.

I put further development in the freezer because it's already too creepy. I'd run it on some porn gif, and after a long search it had built a graph pointing to a residence in rural Russia with pictures of a local volleyball club.

To imagine that intelligence agencies probably have much better gathering tools is so insane to think about.

A story about how a busy programmer became responsible for training interns.

So I was put in charge of a team of interns and had to teach them to work with Linux, coding (Bash, Python and JS) and networking overall.
None of the interns had any technical experience, skills, knowledge or talent.
Furthermore the task came to me as a surprise and I didn't have any training plan nor the time.

Case 0:
Intern is asked to connect to a VM, see which interfaces there are and bring up the one that's down (eth1). He shuts eth0 down and is immediately disconnected from the machine, being unable to connect remotely.

Case 1:
Intern researches Bash scripting via a weird android app and after a hour or so creates and runs this function: test(){test|test&}
He fork-bombed the VM all other interns used.

Case 2:
All interns used the same VM despite the fact that I created one for each.
They saved the same ssh address in Putty while giving it different names.

Case 3:
After explicitly explaining and demonstrating to the interns how to connect to their own VMs they all connect to the same machine and attempt to create file systems, map them and etc. One intern keeps running "shutdown -r" in order to test the delay flag, which he never even included.

Case 4:
All of the interns still somehow connect to the same VM despite me manually configuring their Putty "favorites". Apparently they copy-paste a dns that one of them sent to the entire team via mail. He also learned about the wall command and keeps scaring his team members with fake warnings. A female intern actually asked me "how does the screen knows what I look like?!". This after she got a wall message telling her to eat less because she gained weight.

Case 5:
The most motivated intern ran "rm -rf" from his /etc directory.
P.S. All other interns got disconnected because they still keep using his VM.

Case 6:
While giving them a presentation about cryptography and explaining how SSH (that they've been using for the past two weeks) works an intern asked "So is this like Gmail?".
I gave him the benefit of the doubt and asked if he meant the authorization process. He replied with a stupid smile "No! I mean that it can send things!".

FML. I have a huge project to finish and have to babysit these art majors who decided to earn "ezy cash many" in hightech.

Adventures will be continued.

The programmer and the interns part 2.

We will discuss numerous events that happened over the past week or so.

Case 0:
We had our weekly engineering meeting. The interns were invited as well.
We hold meetings in the generic, big, corporate meeting rooms with a huge table in the middle.
There were more than enough chairs for everyone yet the most motivated and awkward intern (let's call him Simon) chose to stand, cause "it's cool man, I always stand". At this point we all know that he probably read about Agile stand up meetings and is confusing it with this one. Otherwise he's simply trying to stand out from the rest. (See what I did there?)
Anyway the meeting has started way later than planned (what a surprise) and took much longer than Simon expected. Everybody is sitting and listening to the CTO while occasionally glancing at the weird looking intern standing awkwardly and refusing to sit because it would make his original intentions pointless. He even tried to nod whith a serious face and his hands crossed when the CTO said something and looked at his general direction. The meeting was about a hour and a half long but with the delay it was at least 2.5 hours.
At the end Simon was so exhausted that he fell asleep on the office puff, was forgotten and locked inside. 3 hours later when I was home I received a call from him with his sleepy-trying-to-sound-awake voice telling the news. Lucky there's a 24/7 Noc team that could rescue him.

Case 1:
An intern who was late on his Linux test connected to every test VM (should I remind you that each one has a personal VM but they share passwords for their roots?) and tried to reset it with "sleep 10s; shutdown -h now".
He took down all 13 of those so I had to turn them on and switch passwords again.

Case 2:
One of the interns didn't do any of his training chores. Apparently he forgot what he was told to use, ignored all online documentation and used Windows CMD with Linux commands for almost a week already.

Case 3:
Simon uses Vim to write all text possible. Even mails, he then selects all and copies into the mail body. He spent half a day on a homework task I gave them. He wrote everything inside one text file using Vim. When he was done he saved the file and quit the editor. He then said "Oh shit! I've forgot to sign my name!". I explicitly told him that theres absolutely no need for that because I see which mail the file was sent from. He said "I don't even need a program for that!" and gave a couple of strokes on the keyboard.
Later I received an email from him with a .txt attachment. When I opened it the only text that was inside was "by Simon ;)".
I logged to his machine and checked the last command ran on the file:
echo "by Simon ;)" > linuxtasks.txt

Case 4:
The girl here uses a MacBook. She keeps getting confused with the terminal windows and rebooting her own machine instead of the remote VM.

Case 5:
Haven't checked yet how this happened but one of the interns deleted the gui from his local Centos.

A man flying in a hot air balloon suddenly realizes he’s lost. He reduces height and spots a man down below. He lowers the balloon further and shouts to get directions, "Excuse me, can you tell me where I am?"

The man below says: "Yes. You're in a hot air balloon, hovering 30 feet above this field."

"You must work in Information Technology," says the balloonist.

"I do" replies the man. "How did you know?"

"Well," says the balloonist, "everything you have told me is technically correct, but It's of no use to anyone."

The man below replies, "You must work in management."

"I do," replies the balloonist, *"But how'd you know?"**

"Well", says the man, "you don’t know where you are or where you’re going, but you expect me to be able to help. You’re in the same position you were before we met, but now it’s my fault."

@dfox so is devrant turned out to be what you thought/hoped it'd be when you first started it, or is it different than the initial idea?

Probably an unpopular opinion here:

I don't use Linux and I genuinely love Windows!

Long rant ahead, but it's worth it.

I used to work with a professor (let's call him Dr. X) and developed a backend + acted as sysadmin for our team's research project. Two semesters ago, they wanted to revamp the front end + do some data visualization, so a girl (let's call her W) joined the team and did all that. We wanted to merge the two sites and host on azure, but due to issues and impeding conferences that require our data to be online, we kept postponing. I graduate this semester and haven't worked with the team for a while, so they have a new guy in charge of the azure server (let's call him H), and yesterday my professor sends me (let's call me M), H and W an email telling us to coordinate to have the merge up on azure in 2-3 days, max. The following convo was what I had with H:

M: Hi, if you just give me access to azure I'll be able to set everything up myself, also I'll need a db set up, and just send me the connection string.
H: Hi, we won't have dbs because that is extra costs involved since we don't have dynamic content. Also I can't give you access, instead push everything on git and set up the site on a test azure server and I will take it from there.
M: There is proprietary data on the site...
H: Oh really? I don't know what's on it.
<and yet he knows we have no dynamic data>
M: Fine, I'll load the data some other way, but I have access to all the data anyway, just talk to Dr. X and you'll see you can give me access. Delete my access after if you want.
H: No, just do what I said: git then upload to test azure account.

Fine, he's a complete tool, but I like Dr. X, so I message W and tell her we have to merge, she tells me that it's not that easy to set it up on github as she's using wordpress. She sends me instructions on what to do, and, lo and behold, there's a db in her solution. Ok, I go back to talking to H:

M: W is using a db. Talk to her so we can figure out whether we need a database or not.
H: We can't use a database because we want to decrease costs.
M: Yes I know that, so talk to her because that probably means she has to re-do some stuff, which might take some time. Also there might be dynamic content in what she's doing.
H: This is your project, you talk to her.
<I'm starting to get mad right now>
M: I don't know what they had her do apart from how it interfaces with what I've done.
H: We still can't have databases.
M: Listen, I don't do wordpress, and I'm not gonna mess with it, you talk to her
H: I won't do any development
<So you won't do any dev, but you won't give me access to do it either?>
M: Man, the bottleneck isn't the merging right now, it's the fact that W needs a db
H: I know, so talk to her
M: THE RESTRICTION TO NOT HAVE DATABASES IS NOT MINE, IT'S YOURS, YOU TALK TO HER. I can't evaluate whether it's a reasonable enough reason or not since I don't know the requirements or what they're willing to spend.
H: It's your project.
M: Then give me fucking access to azure and I'll handle it, you know you'll have to set up wordpress again regardless whether we set it up the first time.
H: Man just do your job.

At this point I lost it. WHAT A FUCKING TOOL. He doesn't wanna do dev work, wants me to go through the trouble of setting up on a test subscription first, and doesn't want to give me access to azure. What's more, he did shit all and doesn't want to anything else. Well fuck you. I googled him, to see if he's anyone important, if he's done anything notable which is why he's being so God damn condescending. MY INTERNSHIP ALONE ECLIPSES HIS ENTIRE CV. Then what the fuck?

There's also this that happened sometime during our talk:

M: You'll have to take to Dr. Y so he'll change the DNS to point to the azure subscription instead of my server.
H: Yea don't worry, too early for that.
M: DNS propagation takes 24 hours...
H: Yea don't worry.

DNS propagation allows the entire web to know that your website is hosted on a different server so it can change where it's pointing to. We have to do this in 2-3 days. Why do work in parallel? Nah let's wait.

I went over his head and talked to the professor directly, and despite wanting to tell him that he was both drunk and high the day he hired that guy, I kept it professional. He hasn't replied yet, but this fucker's pompous attitude is just too much for me alone, so I had to share.

PS: I named his contact as Annoying Prick 4 minutes into our chat. Gonna rename him cz that seems tooooooo soft a name right now.
