Turn your old computer into a music server with VortexBox Linux
Wednesday, March 10, 2010 @ 23:55:14 CET by tw45admin (55 reads) |  donadony writes VortexBox is a free, open source (GPL v3), quick-install ISO that turns your unused computer into an easy-to-use music server/jukebox. Once VortexBox has been loaded on an unused PC, it will automatically rip CDs to FLAC and MP3 files, ID3 tag the files , and download the cover art. Vortexbox will then serve the files to network media players such as Logitech Squeezebox, Sonos, or Linn. The music files can also be streamed to a Windows or Mac OSX system.

Intro to IO Profiling of Applications
Wednesday, March 10, 2010 @ 18:37:10 CET by tw45admin (35 reads) | One of the classic problems in designing storage solutions is that we don’t know what kind of IO performance applications need. We may have some empirical knowledge, “switching to SSD’s improved by wall clock time by 25%,” or, “adding an extra drive improved my application performance by 11%.” While this information is helpful to some degree what is missing is the understanding of why performance improved and by extension, what are the driving mechanisms behind the performance improvement. Perhaps equally important for the application developers is that understanding the driving forces of IO performance for your application can be used to improve the IO performance, if needed.

Installing wxPython 2.8 on Debian Lenny
Wednesday, March 10, 2010 @ 14:47:49 CET by tw45admin (36 reads) |  Actually Debian has the python-wxgtk2.8 package which you can simply apt-get if you wish to have it installed as part of Python 2.5 which is the stable version for Lenny. I’m adding wxPython 2.8 to Python 2.6, which I installed from source. I mostly followed what the official wxPython installation guide says. It was not a smooth installation for me, so this is my own installation note. The version is 2.8.10.1. First, download the tarball for wxPython from the official repository. Here I assume the archive is downloaded to /usr/local/src/wx. You need to first build wxWidgets, and then build extension module for wxPython. Anyways, decompress and untar, and create a working directory for building wxWidgets...

Ubuntu, The Ultimate Linux Distribution
Wednesday, March 10, 2010 @ 13:18:42 CET by tw45admin (77 reads) |  From its Debian roots to its commercially available support to its overwhelming popularity, Ubuntu is the ultimate Linux distribution. For me, Ubuntu became a significant force within the Linux community with its 2006 releases: 6.04 and 6.10. From April 2006, I've installed and used every new version and anticipate each new one the way a child anticipates toys on Christmas morning. But, have you ever wondered why is Ubuntu the ultimate Linux distribution? Why is it so popular? Why did Canonical choose Debian as its distribution template? And, why did Mark Shuttleworth believe in Linux so much that he chose to create Canonical to support it? Let's take a look at Ubuntu Linux and see if we can figure out why it is, in fact, the ultimate Linux distribution.

Twitter to screen links for phishing scams
Wednesday, March 10, 2010 @ 13:11:37 CET by tw45admin (33 reads) |  Twitter launched a new link-screening service on Tuesday aimed at preventing phishing and other malicious attacks against users of the popular microblogging service. Part of the new service is a new Twitter tool to shorten URLs, so users will see some links in email notifications and direct messages from other users written as twt.tl, Twitter said in a blog post. "By routing all links submitted to Twitter through this new service, we can detect, intercept, and prevent the spread of bad links," the blog post said. "Even if a bad link is already sent out in an email notification and somebody clicks on it, we'll be able keep that user safe," it said without elaborating.

March 31, 2010: Document Freedom Day
Wednesday, March 10, 2010 @ 13:06:32 CET by tw45admin (25 reads) |  International free software organizations have declared the last Wednesday in March to be Document Freedom Day (DFD). Activities and information events will take place all over the world, including Canada, United Kingdom and the United States. "Will you be able to read your documents 20 years from now?" ask the organizers in their rally cry for DFD 2010. Their claim is that only open standards like the Open Document Format offers a guarantee. Everyone can use these formats without restrictions or implement them in software.

How Ruby Manages Memory and Garbage Collection
Tuesday, March 09, 2010 @ 16:57:06 CET by tw45admin (62 reads) | Garbage Collection and the Ruby Heap is a presentation given by Joe Damato and Aman Gupta at the recent LA Ruby Conference. You only get the slides for now (all 70 of them!), but they're very detailed and can almost work as a standalone concise e-book on Ruby's garbage collection system. Joe and Aman take a look at C memory management vs Ruby and show the difference between the stack and the heap. As a garbage collected language, Ruby takes the easy route by putting everything on the heap and the presentation demonstrates how the MRI (Matz's Ruby 1.8) does this, as well as how objects are tracked within memory (right down to the underlying C structs).

Klaatu Recommends Nikto for Web Security
Tuesday, March 09, 2010 @ 13:55:32 CET by tw45admin (61 reads) | Nikto is a free, open source, command line scanning script used for testing your web server’s security. It checks for thousands of vulnerabilities and potential security weaknesses such as default files and programs, outdated servers, insecure files, server and software misconfigurations. Nikto uses a configuration file, three dozen plugins for testing and a handful of templates for reporting. Nikto is not a weapon nor is it a remedy for damage that’s already occurred. It is an assessment tool that, when used properly, may prevent a host of potential security threats from becoming reality.
