PHP fsockopen for FAST DNS lookups over UDP

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 8.8.8.8, 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.

Boosting Googles PageSpeed Module with TMPFS

Boosting Googles PageSpeed Module with TMPFSGoogle's mod_pagespeed speeds up your site and reduces page load time. This open-source Apache HTTP server module automatically applies web performance best practices to pages, and associated assets (CSS, JavaScript, images), all transparently like a Squid Proxy.

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!

Get Number of Running Proccesses with PHP

Apache Httpd Number ProcessesRecently 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.

Advanced Windows Batch File Scripting

Windows Batch Programming ExampleIf 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.

:SETPROMPT
set PROMPT=$_[%USERNAME%@%USERDOMAIN%]$S[$P]$_$M$G && EXIT /B

Create an AT job to run as system in Notepad++ IDEMy 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.

King Penguin Linux Notebook

King Penguin Linux Notebook 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

Alienware M18xR2 Review of Dells fastest LaptopClevo > 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

Bash Script to Create index.html of Dir Listing

Bash Script to Create index.html of Dir ListingIf 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!

Hacking and Hackers

The use of "hacker" to mean "security breaker" is a confusion on the part of the mass media. We hackers refuse to recognize that meaning, and continue using the word to mean someone who loves to program, someone who enjoys playful cleverness, or the combination of the two.
