Add some resource

[s18alg]

Hello!
I added two little resource I find very useful.

I hesitated to create a "Math" category for the first one but I don't know if it's fine to have a category for a single link so I added it to general. It may be an interesting idea in the future to gather a bit more resource on the topic to create a dedicated category.

Thank you for reading and have a nice day!

Please get rid of the backtick after math.

Typo fixed!

Thanks, I guess in order to push to store, we'll merge this after the switch. @S3B4S what do you say?

[s18alg]

@lostdesign not sure of what you mean here, but i'll keep an eye on that PR and make sure it can be merge at any time

@SuliacLEGUILLOU We're changing store.json into multiple <category>.json files, see #91. That's what @lostdesign means. :)

I'm surprised we didn't have https://internetingishard.com/ already, it's a great resource. Though I'd prefer a link to the homepage instead of directly to the first lesson.

Sounds like a nice idea indeed!
I'll keep an eye on that PR and adapt it once you are done with the split.

Regarding of the lesson/homepage thing, I felt like a link to the direct content was more useful as I prefer getting straight to the point, but I'll edit it to indicate the homepage when I'll work on that PR again.

@SuliacLEGUILLOU #91 has been merged! So if you could resolve the conflicts and edit as above discussed that'd be great 👍

Also, please reopen this into master.
