intrace - intrace - Traceroute-like application piggybacking on existing TCP connections - Google Project Hosting
InTrace is a traceroute-like application that enables users to enumerate IP hops exploiting existing TCP connections, both initiated from local network (local system) or from remote hosts. It could be useful for network reconnaissance and firewall bypassing.September 09 2011

Home - PHP-FPM
PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites.These features include:
Adaptive process spawning (NEW!)
Basic statistics (ala Apache's mod_status) (NEW!)
Advanced process management with graceful stop/start
Ability to start workers with different uid/gid/chroot/environment and different php.ini (replaces safe_mode)
Stdout & stderr logging
Emergency restart in case of accidental opcode cache destruction
Accelerated upload support
Support for a "slowlog"
Enhancements to FastCGI, such as fastcgi_finish_request() - a special function to finish request & flush all data while continuing to do something time-consuming (video converting, stats processing, etc.)

The Monkeysphere Project
The Monkeysphere project's goal is to extend OpenPGP's web of trust to new areas of the Internet to help us securely identify servers we connect to, as well as each other while we work online. The suite of Monkeysphere utilities provides a framework to transparently leverage the web of trust for authentication of TLS/SSL communications through the normal use of tools you are familiar with, such as your web browser0 or secure shell.October 28 2010

jcole’s weblog: Jeremy Cole’s take on life. » Blog Archive » The MySQL “swap insanity” problem and the effects of the NUMA architecture
When running MySQL on a large system (e.g., 64GB RAM and dual quad core CPUs) with a large InnoDB buffer pool (e.g., 48GB), over time, Linux decides to swap out potentially large amounts of memory, despite appearing1 to be under no real memory pressure. Monitoring reveals that at no time is the system in actual need of more memory than it has available; and memory isn’t leaking, mysqld‘s RSS is normal and stable.Normally a tiny bit of swap usage could be OK (we’re really concerned about activity—swaps in and out), but in many cases, “real” useful memory is being swapped: primarily parts of InnoDB’s buffer pool. When it’s needed once again, a big performance hit is taken to swap it back in, causing random delays in random queries. This can cause overall unpredictable performance on production systems, and often once swapping starts, the system may enter a performance death-spiral.

Thoughts about this DIY-Thumper and storage in general - c0t0d0s0.org
But there is another misunderstanding: There is no unimportant data, data is important or it's outdated, but then it was important at a certain point of time. When it isn't or wasn't important you wouldn't have stored it on disk. You can't classify data in important or unimportant. But you seperate in different classes of needed availability. There is data which you need it at high speed at any time and there is data that you need with a low frequency and it's sufficient to have it after minutes, hours, days.May 08 2010

isolate - Project Hosting on Google Code
The Problem All your Unix applications run with the full authority of the account that launched them: your browser can read your SSH private key, your mail reader can mine your browser history, your image converter can delete all your email, and so on. So it is not safe to listen to songs from untrustworthy sources: a maliciously-crafted MP3 could crack your music program and use its authority to send your SSH key to a maniac with an evil mustache. What's an "untrustworthy source"? The Internet would be one example... The Solution This utility, isolate, runs processes in a chroot-ed environment, with constrained resource limits, as a random UID, and with limited access to the X server. An isolated program ("isolatee") no longer has all the authority of your user account, but you can still enjoy its legitimate functionality. You can play even maliciously-crafted songs in an unsafely implemented music player, with greatly minimized risk to your other data.October 12 2009
