The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
H: preserves hard-links
A: preserves ACLs

NGINX Tuning For Best Performance

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.

Some examples of SNAT, DNAT with iptables with comments

mainly used in start-up script

How to test 'safely'

When we play with iptables aka firewall we might end up in situation, where we execute rule, which has unforseen impact - lock yourself out. Recovering from this situation is necessity.

How to:

Enable reboot via SMS.

Test all commands in shell first before putting them into Start-up script. This way the command will be wiped out, when unit is rebooted.

`__invoke` VS `function` VS `Closure`

This gist is about:

Mainly:

function cannot (should not) be used when side-effects occur

$ wget -e robots=off -r -np 'http://example.com/folder/'

-e robots=off causes it to ignore robots.txt for that domain
-r makes it recursive
-np = no parents, so it doesn't follow links up to the parent folder

Examples for how a __toArray() magic method could be useful in PHP.

In a nutshell, __toArray() would not be as useful when you have full control over the entire codebase.

But where __toArray() would be extremely useful is in interfacing with existing code that expects arrays and wants those arrays to be a specific format. Using classes and type-hinted methods allow to encapsulate the intelligence into the class, and using __toArray() makes for a nature use-case.
