Free O'Reilly books and convenient script to just download them.
Thanks /u/FallenAege/ and /u/ShPavel/ from this Reddit post
How to use:
- Take the
download.sh
file and put it into a directory where you want the files to be saved. cd
into the directory and make sure that it has executable permissions (chmod +x download.sh
should do it)- Run
./download.sh
and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.

// Objective is to explain describe(), it(), and before()/etc hooks | |
// 1. `describe()` is merely for grouping, which you can nest as deep | |
// 2. `it()` is a test case | |
// 3. `before()`, `beforeEach()`, `after()`, `afterEach()` are hooks to run | |
// before/after first/each it() or describe(). | |

// Which means, `before()` is run before first it()/describe() |

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.
Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon
with HyperThreading enabled, but it can work without problem on slower machines.
You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
