While reading up on gethostbyaddr on PHP.net, I saw a nice idea for using fsockopen to connect over UDP port 53 to any Public DNS server, like Google DNS
18.104.22.168, and sending the reverse addr lookup in oh about 100 bytes, then getting the response in oh about 150 bytes! All in less than a second. This is how/why to read/write data directly to the wire! This would be extremely valuable for use in things like my online header tool because it's faster than any other method. As usual, I went a bit overboard optimizing it to be lean and fast.
With TMPFS you can dramatically improve the speed of mod_pagespeed and the webpages served by it. TMPFS will store/serve the optimized PageSpeed output directly from RAM!
PHP's fsockopen function lets you open an Internet or Unix domain socket connection for connecting to a resource, and is one of the most powerful functions available in the php language.
Recently I had to setup a script to curl 10k urls, but it could only do 500 requests at any one time. In order to work under that limit, I created a function that returns the number of currently running processes on the machine in an extremely fast and efficient way, thus allowing the curl_multi requests to queu themselves such as GNU xargs.
If for some reason you need to use windows .bat batch file scripting to do some task, or you just want to learn the most universal batch programming language on Windows machines, you lucked out and found the AskApache example. My expertise is the shell, in this article the shell is Windows
cmd.exe. It has some pretty advanced windows shell usage, including pipes and redirection, but it's the modular linux-like coding approach that earns this script it's "advanced" title.
set PROMPT=$_[%USERNAME%@%USERDOMAIN%]$S[$P]$_$M$G && EXIT /B
My favorite tool (and I've tried sooo many) for editing most Windows files and especially .bat files is the free and open-source Notepad++. Set that up and you will have a color-syntax-highlighted editor for Batch Scripting that works very very well.
The machine itself is super super ultra-thin, wafer thin, very cool looking. It's crazy light, I was amazed how slick it looked when it arrived.
Huge amount of open-source hardware/chipsets/etc.. The first time I went through the dmesg I was smiling. 2 USB 3.0 ports, and they actually work as promised, very very fast transfer speeds to my USB 3.0 external SSD. Incredible speed, boot time is the fastest I've ever seen. Starts at $720, mine was $1,800
Clevo > Dell > Alienware. This is the best of the best. I've had mine for about a year now and have had 0 issues with it. It's fast, as in crazy unreal fast. It's not a huge server slice, but it acts like it. With 16GB of RAM, 8 cpus, SSD Raid, USB-3, and of course the graphics. Downside: about $3.5 - $6k
A pure bash alternative to the python reflector, using curl, xargs, and sort for ranking Arch Linux mirrors.
Nice and simple. Short and sweet.
Want to redirect all links with any uppercase characters to lowercase using pure mod_rewrite within an .htaccess file? Sure why not! OR how to use RewriteMap and mod_speling for those with access to
If you use Apache to auto-generate directory index listings of files/dirs, and you have a large number of files and directories in the root directory and/or slow IO speed, then generating the index could take Apache over a minute!
