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?26 -
How my keyboard evolves:
0. Like any normal man, I started with a cheap standard Qwerty keyboard. As I began learning programming, I wanted something more elegant, so...
1. I've been using layout Dvorak (and then Programmer Dvorak) for like 5 years+ now. Anyone has intention to type on my machine soon gives up or even is blocked by me from the very start. It always takes a couple of minutes to explain to them what's going on here. They think I'm weird. I feel untouchable :)
2. My first mechkey was a 104-key Filco. Time flew by and I wanted my thing to be more compact so I went for a 66% and a TKL.
3. Recently I find out that though my keyboard is not a full-sized, there're yet some keys I've never touched (the bottom right modifiers, scroll lock, etc), so I look for a leaner one: HHKB and its alike but with slight remappings. Now I'm satisfied with the tiny, corners-trimmed keyboard but others look at it and ask how it is even possible to scroll the web page using the thing.
Prob 1: my boss can never type on my keyboard. Sometimes he still grumbles when he cannot correct my fouls right on my machine.
Prob 2: my keyboards at home and at work are not the same and some keymapping cannot applied to one of the two. That's async.21 -
I built very involved code with multiple auth systems, async programming, business logic, error handling, and etc. I was asking for the missing environment variables during the call with devops and had a screen share going. Environment variables were the last thing I needed before knowing if it would work. I filled in the config and all the code worked perfectly.
The devs lost their shit. One suggested that I had somehow tested it beforehand because it is impossible that it would work the first time. “How? I didn’t have config details or access to any of the remote APIs until now.”
The dev lead finished the call with, “That was some big brain next level shit.” Then they went and reviewed and tested it after the call and didn’t have much to suggest besides naming nitpicks.
It was at that point I knew I was a hero to the other devs.3 -
Modern web frontend is giving me a huge headache...
Gazillion frameworks, css preprocessors, transpilers, task runners, webpack, state management, templating, Rxjs, vector graphics,async,promises, es6,es7,babel,uglifying,minifying,beautifying,modules,dependecy injection....
All this for programming apps that happen to run inside browsers on a protocol which was designed to display simple text pages...
This is insanity. It cannot go on like this for long. I pray for webasm and elm to rescue me from this chaos.
I work now as a fullstack dev as my first job but my next job is definitely going to be backend/native stuff for desktop or mobile. It seems those areas are much less crazy.10 -
JavaScript Motherfucking Asynchronous Bullshit.
I get it, for quite some stuff, async is very, very useful. But why on fucking earth do so goddamn many functions NEED this (and those callback functions) and can't do without?!
If there would be good and nicely understandable await documentation that actually fucking works, I'd be so happy.
I've currently got .then after .then after motherfucking then and its irritating me to no end as it, in this context, shouldn't even be necessary. This thing I'm writing doesn't give a fuck if something takes a few milliseconds before the rest of the program can continue!!
Fuck asynchronous programming in JavaScript for goddamn everything.
(I do love JavaScript!)27 -
Im now working as a fulltime dev for 3 years. I do programming since im 9 and now that I collected some experience, I have to to say, its horrible. Seriously. What the fuck is wrong with german internship companys? Letting me do 3 years of FUCKING CRYSTAL REPORTS. IN A DEVELOPMENT TEAM THAT CONSISTS OF A TEAM LEAD THAT ACTUALLY HAS TO LEARN SHIT LIKE PROPER OOP AND ASYNC/AWAIT FROM ME. THEY EVEN ASKED ME IF I CAN DROP OF MY HOBBY PROJECTS TO WORK ON SAMPLES THAT THEY CAN LEARN FROM! NO! FUCK! JUST BECAUSE THESE DOUCHBAGS ARE TOO LAZY TO FUCKING LEARN TECHNOLOGY THEY SHOULD BE PASSIONATE ABOUT IN THEIR FREE TIME, IM NOT MAKING IT MY JOB TO FREAKING SHOW THEM THAT HAVING A STATIC CLASS CONTAINING ALL MODELS EVER EXISTED IN THE APP IS A BAD THING! SERIOUSLY, THERES ONLY ONE INSTANCE OF EVERY MODEL WE HAVE! AND THEN THEY BLAME SQL SERVER FOR RACE CONDITIONS WHEN TRYING ASYNC!!!! WHAT THE FUCK!! AND STILL, IF I TELL THEM WHATS WRONG, IM AN IDIOT BECAUSE IM A JUNIOR! Please tell me that i didnt waste 10 years of my life dedicating to such bullshit. Will that change? Is it company specific?9

"Why wait when you can ASYNC ":D
Heard this somewhere long back. Coming back to me now while learning node.5 -
Not quite a rant, but looking for opinion/advice.
I have been programming for a little over a year now, excluding those cringy Lua scripting days with if statement hell. I'm pretty far ahead most of the people in my course (1st year Software Engineering), but I'm at this awkward point where I know quite a bit but not enough. All of my projects so far have been small 1-2 source file programs, mostly in javascript although Python is my main hoe. At the moment I'm reading a book on machine learning and I feel like I'm doing fine, not struggling too much with it, but I don't feel confident at all in my abilities. I had two programming internship interviews half a year ago, both of which I wasn't accepted in. I've been thinking of contributing to an open source project lately to get some "real world" experience but I can't find a good project to start with and just don't feel like I'm good enough. There are also a lot of small things I come across such as async and coroutines in Python which I'm not familiar with yet and they make my confidence drop even lower. I'm guessing most of you have been in a similar position. Would you have any advice for me? Should I search for a project or should I keep on studying with books?2 -
Node: The most passive aggressive language I've had the displeasure of programming in.
Reference an undefined variable in a module? Prepare to waste your time hunting for it, because the runtime won't tell you about it until you reference a property or method on the quietly undefined module object.
Think you know how promises work? As a hiring manager, I've found that less than 5% of otherwise well-experienced devs are out of the Dunning Kruger danger zone.
Async causes edge cases and extra dev effort that add to the effort required to make a quality product.
Got a bug in one of your modules? Prepare yourself for some downtime because a single misplaced parentheses can take out the entire Node process, killing unrelated pages and even static file hosting.
All this makes for a programming experience that demands much higher cognitive load, creates more categories of bugs, and leads to code bloat/smell much more quickly than other commonly substituted languages.
From a business perspective, the money you save on scaling (assuming your app is more compute efficient under Node) is wasted on salaries and opportunity costs stemming from longer dev time, more QA, and more frequent outages.
IMO, Node is an awesome experiment, a fun language, a great tool for specific use cases, and a terrible fucking choice for an entire website.8 -
People around me and clients are increasingly saying i am a genius, because i show them an app i made in react-native or some crappy site i set up in a week as POC.
While im quite noobish still, i barely read publications out of interests, and most of the time i just put in async/await somewhere just to see if it makes the promise work or not, because i dont understand promises fully, and I think in general i just accomplished very little in the 5 years I have been programming
It is really putting pressure on my impostor syndrome, even more when i talk with my peers who can tell who was the driving force behind ES6 :/9 -
Looking for platform specific language options for a new project at work and reading articles from well known sources.
If you start your article with something like, "when I think of a good programming language, I think of JavaScript", I'm going to punch out of your shitty opinion faster than an async function.
When you're trying to convey an unbiased message you generally don't start with, "I'm an absolute shill for {language}".
What the fuck happened to journalistic integrity?7 -
Unrelated to programming:
If I'm doing async karaoke (i.e., I'm using an app like Smule where one person records one part and you join or vice versa) and the other person decides to randomly COME INTO MY LANE and not just sing my part, but sing it off-key, I get irrationally annoyed about it. It's great if they do that at the beginning of the song because then you can just bail. But when they do it at like the very end, I'm like ... 😬 -
Only in React packages...
When you follow the documentation to the exact dot and you get an error and nothing works.
And the stack trace gives you an error coming out of some deep async call, made many calls before the error.
Therefore the stack trace has nothing to tell you.
Equivalent of a brick falling on your head, just bad luck, who said programming should be deterministic anyway...1 -
for my job I need to know,
Programming, C#, Optimization, Multithreading and Async code, Working certain tools, Reading difficult written code, Understanding, Physics, Networking, Rendering, Codeloops, Memory management, Profiling tools, Being able to make Jira tickets and read Jira tickets. Understanding source control branching, merging, push and pull. bug fixing.
And I write almost 1 line of code a week on average..
I'm a programmer.2 -
Guys cover your eyes I'm gonna say two bad words inside a paragraph
Fuck JavaScript and asynchronous programming - I'm not skilled enough for this so I have to insult it periodically until I'm skilled enough to know partially more than now what the fuck I'm doing (therefore the times I use bad words when referring to js and async programming will decrease - or maybe at the increase of knowledge, my usage of bad words will augment. Only time will tell).15 -
Anyone out there a Scala fan? I am! Seems like most of the stories here are quite negative but positively is my thing so here's my 2 cents:
Scala is an amazing data processing language. It's a functional language with a lot of really great things like a consistent collection library api, case classes, brilliant async library's like Akka Actors, and plenty of solid learning resources like Twitter school and Martin Odersky's online course.3 -
Modern Web Developer
(To the tune of "I Am the Very Model of a Modern Major-General" from Gilbert and Sullivan's "The Pirates of Penzance")
I am the very model of a modern web developer
I’m quite fluent with JavaScript; An HTML whisperer
My code is clean and elegant, I genuinely innovate
And even know my way around a Promise and async / await
I’m very well acquainted too with matters vector graphical
I understand why SVG coordinates seem magical
And even without Photoshop I elegantly can produce
A mockup or a logo in most any format that you choose
[Chorus]
A mockup or a logo in most any format that you choose
A mockup or a logo in most any format that you choose
A mockup or a logo in most any format that you choose
I'm quite adept at ES6 expressions like destructuring
I know the ins and outs of functional reactive programming
In short, in matters browser-based or Node.js if you prefer
I am the very model of a modern web developer
[Chorus]
He is the very model of a modern web developer
I know our mythic history, the humble start, the browser wars
I know why Douglas Crockford fought the battle over ES4
The World Wide Web Consortium and Ecma International
My knowledge of our legacy is truly supernatural
With LESS and SASS and CSS, designing for mobility
I’ll perfectly apply the right amount of specificity
From custom fonts and parallax to grid and flex and border-box
I know most every tip and trick both common and unorthodox
[Chorus]
He knows most every tip and trick both common and unorthodox
He knows most every tip and trick both common and unorthodox
He knows most every tip and trick both common and unorthodox
And when it comes to lazy loading, bundling up and splitting code
There’s nothing quite like Webpack, which of course is built on top of Node
Considering my resume, I’m certain that you will concur
I am the very model of a modern web developer
[Chorus]
He is the very model of a modern web developer
When new frameworks and libraries emerge I must be ravenous
And gobble up the hot new thing, my appetite is bottomless
React and Vue and Angular, Immutable, RxJS
The list will be outdated long before I'm finished singing this
My pull requests rely on multitudinous utilities
To help me lint and test and build, a deluge of analyses
And every single day there are a hundred thousand more to learn
The web is going through an irresponsible amount of churn
[Chorus]
The web is going through an irresponsible amount of churn
The web is going through an irresponsible amount of churn
The web is going through an irresponsible amount of churn
This pace is agonizing! Code from yesterday is obsolete!
The speed of innovation is enough to knock me off my feet!
It's happening too fast! I can’t keep up! I’m tired! It’s all a blur!
I am the very model of a modern web developer!
[Chorus]
He is the very model of a modern web developer!1 -
So i have been coding in python and its my main language. Give me 2 reason why i should learn js(node).this question aroused coz i have to work with MS Bot framework and they just support c# & node js (python is still in prev) and their code has asynchronous programming in both *cries in corner also suggest me good resources to lesrn what async prog2

Being new to NodeJS, I wanted to use the framework for a small script that involved connecting to a MySQL database and updating 1500+ records.
With NodeJS's preference towards functional programming over sequential, I wanted to do things the NodeJS way with callback functions instead how I'm used to doing it, using loops (and all the MySQL functions were async).
I couldn't update all the rows at once, so I wrote a callback function that calls back itself after the SQL statement is executed. A recursive callback function... am I doing this right?7
