I Super-accurate computer clock created
A free pies of software that allows computers to keep phenomenally accurate time has been developed by researchers in Melbourne. The software, called RADclock, should improve everything from Skype conversations to the tracking of subway trains.

For computers to communicate effectively keeping accurate time is vital. Every application or service that relies on computers collaborating implies that the computers are synchronised,” Julien says.

The problem is, while the clocks built into most computers keep time well, they’re not 100 per cent accurate. These clocks monitor how many times per second a quartz crystal inside the computer vibrates. But this ‘crystal frequency’ is a little different for every crystal, and changes all the time, due to variations in temperature, for example. “And that can make a big difference when errors accumulate,” he says.

At the moment, RADclock works only with open source software, such as Linux and FreeBSD, but a Windows version may be available in the future.

II SIFTR Committed
On July 3, Lawrence Stewart committed SIFTR (Statistical Information For TCP Research) to HEAD. SIFTR was part of the Improvements to the FreeBSD TCP Stack project that the Foundation funded last year. SIFTR is a kernel module that logs a range of statistics on active TCP connections to a log file. It provides the ability to make highly granular measurements of TCP connection state, aimed at system administrators, developers and researchers. (source: FreeBSD Foundation)

III New jail utility “qjail” published for public usage
This is a news announcement to inform people who have interest in jails, that a new jail utility is available.


Has a file suitable for the pkg_add command or the port make files can be downloaded and a “make install” run.

Qjail [ q = quick ] is a 4th generation wrapper for the basic chroot jail system that includes security and performance enhancements. Plus a new level of “user friendliness” enhancements dealing with deploying just a few jails or large jail environments consisting of 100’s of jails. Qjail requires no knowledge of the jail command usage.

IV HOW-TO: Install Apache Tomcat 6 on FreeBSD 8.0
Calebscreek writes: On a recent whim, I decided to spend a Saturday morning attempting to install Apache Tomcat 6 on FreeBSD 8.0. It turned out that it’s not as straightforward as some GNU/Linux distros*; particularly those that are Debian-based. Through some trial and error, though, I got things working as I liked.

VIII DuckDuckGo: A New Search Engine Built from Open Source
DuckDuckGo is a new search engine focused on relevant results and respecting user privacy. Actually a mash-up of several other sites like Wikipedia, About, Bing, and Yahoo, DuckDuckGo also uses it’s own web crawler: the DuckDuckBot. DuckDuckGo uses what it calls Zero-click search results to try to guess what you are looking for and give it to you directly in your search results. I’ve been using DuckDuckGo for a few weeks now, and I’m impressed. What further impresses me is that the entire site is built on open source tools, ranging from FreeBSD for the operating system to good old-fashioned Perl for the logic.
