A Road to Common Lisp (Common Lisp への道)
これまで、「最近のCommon Lispをどう学ぶとよいでしょう？」と助言を求めるメールをたくさん受け取ってきました。そこで私は、これまでメールやソーシャルメディアに投稿した全てのアドバイスを書き下すことにしました。これが誰かに有益ならば幸いです。

| 22 Hacking Sites, CTFs and Wargames To Practice Your Hacking Skills | |
| InfoSec skills are in such high demand right now. As the world continues to turn everything into an app and connect even the most basic devices to the internet, the demand is only going to grow, so it’s no surprise everyone wants to learn hacking these days. | |
| However, almost every day I come across a forum post where someone is asking where they should begin to learn hacking or how to practice hacking. I’ve compiled this list of some of the best hacking sites to hopefully be a valuable resource for those wondering how they can build and practice their hacking skill set. I hope you find this list helpful, and if you know of any other quality hacking sites, please let me know in the comments, so I can add them to the list. | |

tl;dr I want to use Rust to program robots. Help me find the best core libraries to build on.
Robotic systems require high performance and reliability, but also have enormous complexity in terms of algorithms employed, number of subsystems, embedded hardware control, and other metrics. Development is mostly split between C++ for performance and safety critical components, and MatLab or Python for quick research or task iteration.

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.
For the sake of this example, let’s pretend the subfolder containing your site is named dist.
Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).
