Useful in a pinch, but I would not recommend using these. Make your own. If you plan on using the language, making your own cheat sheet is the best way to learn it. By the time you are able to make one, you know what you use, what you always forget, and what is obscure, but important enough to need a quick refresher.

letney 13 years ago | |

What? Did you even look through at how comprehensive the list of APIs they have online here is? I'm a full-time developer . No way I'm going to waste my time making a cheat-sheet for functions I may only write a few calls to when I could be doing productive coding. There's just too many APIs I need to use.

This is an awesome resource.

Kluny 13 years ago | | |

Yeah dude.

For something I love and want to use all the time, like Python, I'll make my own cheat sheet. For something like MySql, where I have to kick myself to pay attention every thirty seconds, there's no way I'm doing my own cheat sheet. I can barely bring myself to do the actual work.

farinasa 13 years ago | | |

>I'm a full-time developer .

So I take it you must be used to reading documentation and picking up new languages pretty quickly? If you must keep going to the documentation to remember a function, copy it out. I don't see how needing to dig through out of order lists is any more useful than digging through long winded documentation. The point of a cheat sheet is not just remembering the thing, but finding it quickly.

Agreed. Pretty cool when starting out though

Why are you encouraging deprecated mysql_* functions for PHP? overapi.com/php/

eksith 13 years ago | |

Agreed. No note of PDO or even mysqli anywhere, which is pretty unfortunate since novice programmers starting with PDO would be building safer apps.

Slightly off topic, but my rule of thumb: If your project is too big for Sqlite, it's big enough for Postgres. If it's too small for Postgres, it's small enough for Sqlite.

MySQL doesn't absolutely need to fit anywhere in the picture, but of course, this is precluding any host complications for existing projects.

Here's a very nice Common Lisp quickref for anyone else who might be into it: http://clqr.boundp.org/

Is that the Comcast Sports South logo being used for CSS?

CSS -> http://www.csssports.com/

ville 13 years ago | |

Yeah. Looks like they also use a modified FedEx logo for regular expressions, some sort of unofficial Apache logo for mod_rewrite and .jar file type icon[1] for Java :)

The website seems useful, however.

I think I know why. It's the first google images result that is even remotely logo-friendly.

frogpelt 13 years ago | |

Sure is. I wondered if that was on purpose.

I would strongly encourage you to undo the backspace capturing and just allow my browser to go back in navigation the way I like it to.

Shivetya 13 years ago | |

Firefox user here, I was able to backspace just fine. If your somewhere other than top it takes two of them, one to go to top and the next worked just fine.

Now the dzone links requiring registration can take a hike

dylangs1030 13 years ago |

What, no Lisp? I'm offended.

No but seriously this is useful. Bookmarked and pinned, extra points for making it pretty with nice UI. Certainly loads better than sifting through pages of monochrome documentation for a simple, quick answer to small problems.

goldfeld 13 years ago |

Damn, I read that as in "How to program cheat sheets." This is cool. That would be awesome.

gfapps 13 years ago |

We also built something very similar, but targeting mobile users only. We started working on this app as an experiment on html5/cross platform apps; as well as to get server side experience supporting mobile apps.

https://itunes.apple.com/us/app/keyboard-shortcuts!/id489432...

https://play.google.com/store/apps/details?id=com.greenlife....

The traction has been low till now, highlighting the fact that we need to seek a lot of feedback and iterate on it.

Why are some entries very fleshed out and comprehensive (jquery: http://overapi.com/jquery) while others are just links out (vim: http://overapi.com/vim)?

Would love to see more listings of keyboard shortcuts. Overall this is really cool. I'm working on a printed cheat sheet/shortcut product so I'll definitely use this ...

strongvigilance 13 years ago | |

On the about page, they suggest making a pull request if you want to add to it, so I guess it's a work in progress.

Repo is here: https://github.com/overthecs/overthecs.github.com

megablast 13 years ago | |

What, are you kidding? Why are some movies 3 hours long, but some are only 60 minutes?

apl002 13 years ago | |

Yes, I would also love to see something on all the keyboard shortcuts

The javascript one is incomplete.

The example I spotted immediately is the extremely useful document.querySelectorAll()[1] which works very much like $('.someSelector') in jquery, but completely native and supported by pretty much everything.

Done and done.

Very useful. And a really neat execution of a webpage. Was pleasantly surprised on how the elements shift as the page is resized.

notum 13 years ago |

http://overapi.com/religion/ Erm, alright. I was looking for Redis :)

When time travel is achieved, many of us will need this when our future programmer selves come back to retaliate.

dougk16 13 years ago |

Cool idea, and nice execution. Although, I generally work in environments where I have auto-complete or documentation integration of some kind in the editor itself, so it's been quite a while since I've used a cheat sheet...maybe for MySQL if I ever use it again...never seem to become fluent in it.

aroman 13 years ago |

What I want to know is why the icon for regular expressions is the Fedex (or in this case, Regex) logo.

obstacle1 13 years ago | |

Going to go out on a limb here and say it was intended as a cute little joke.

3dptz 13 years ago |

Great work and nice execution.

Although I would rather not see the list of API's be cluttered with items like "Icons", "Logic", "Physics", etc. They are just general concepts and besides they have no actual contents beside a wikipedia and Wolfram Alpha link.

prg318 13 years ago |

Seems like a neat idea, however I can't get any of the cheat sheets to load. Not sure if their servers are getting hammered or what, but all of the language cheat sheets show "Loading..." indefinitely for me.

SeanDav 13 years ago | |

You probably have javascript disabled. I use noscript to do this and got the same until I enabled JS for the site.

microtherion 13 years ago |

It looks like C++ entry is missing my favorite C++ reference site by far: http://www.cppreference.com/index.html

gmrple 13 years ago |

To the author: Small spelling mistake on the Regex Cheat Sheet: the sub title of the anchors group is currently "anchros".

Looks cool! will have to use at some point.

ajq5623 13 years ago |

This is pretty useful! It would be cool if when you clicked a section title (i.e. String) it would take you to general documentation for that topic.

I was clearly expecting a nice and shiny presentation of Linux kernel API (or at least system calls) when clicking on the penguin.

letney 13 years ago |

Where can I recommend missing cheat sheets? I often use the GLSL cheat sheets and I can't see any links to them on the site.

Shopify liquid cheat sheet: http://cheat.markdunkley.com/

The Python Class Special Methods have got extra dashes in. (But I love the clean look & uniformity overall)

hayksaakian 13 years ago |

When is this faster than Google combined with THING.methods ?

At least as far as ruby goes it seems of limited use.

nakovet 13 years ago |

It should be on github pages or something similar, no ads, easy to fork and contribute.

wasd 13 years ago | |

It looks like it is on github pages: https://github.com/overthecs/overthecs.github.com

I don't mind the ads. If its a useful tool, he can feel free to monetize on it.

letney 13 years ago | | |

I just hope he can keep it up to date. Some cheatsheets/APIs can change considerably over subsequent releases.

amerf1 13 years ago |

Simply amazing, exactly what I was looking for thank you very much

suyash 13 years ago |

How does the author plan to keep the cheat sheet updated?

companyhen 13 years ago |

Pretty awesome. Is there anything similar to this?

DaveChild 13 years ago | |

There's Cheatography.com (my site), where you can make your own cheat sheets.

TommyDANGerous 13 years ago |

this is amazing, I am so happy someone took the time to put this together. Love it!!! Where is Objective-C? :(

droncancio 13 years ago |

it would be awesome to query for a cheatsheet on sublime or the console

jordan_clark 13 years ago |

I like it. Nice work.

jfmercer 13 years ago |

bookmarked. good work.

SiVal 13 years ago |

I was looking for the current, living Python (3.3), not the one kept on life support for legacy maintenance (2.7).

tlarkworthy 13 years ago | |

Eh? GAE and Ubuntu LTS
