  • I anatomize a successful open-source project, fetchmail, that was run as a deliberate test of the surprising theories about software engineering suggested by the history of Linux. I discuss these theories in terms of two fundamentally different development styles, the “cathedral'' model of most of the commercial world versus the “bazaar'' model of the Linux world. I show that these models derive from opposing assumptions about the nature of the software-debugging task. I then make a sustained argument from the Linux experience for the proposition that “Given enough eyeballs, all bugs are shallow'', suggest productive analogies with other self-correcting systems of selfish agents, and conclude with some exploration of the implications of this insight for the future of software.
  • Your browser will load a Java Applet from our webserver that will emulate BitTorrent and TCP transfers in upstream and downstream direction. This means, you need to have a Java plugin installed in your browser (If you do not have Java you can download it for free from here).
  • A daemon is a process on UNIX that runs in the background and will typically keep running until it is explicitly told to stop. Examples of daemon processes include web servers (lighttpd and Apache httpd), schedulers (cron and at), DNS servers (bind), mail servers (courier and dovecot), and database servers (MySQL and PostgreSQL).

    The typical web user will probably interact with at least one UNIX daemon in the form of a web server, DNS server, or database server on an average day. These types of processes run in the background on a server somewhere, unattended by any person, working tirelessly to do the work that they were designed for.

    You can background a process on UNIX by putting an ampersand (&) at the end of the command that you started it with.

  • Every time a file is read from your Linux ext3 partition it writes back a attribute to the file detailing the last access time. There are very few programs that actually use this to operate and it slows everything down.

    Disabling atime and diratime on your Linux ext3 file systems can improve disk performance up to 40%!

  • Computer people are fine human beings, but they do a lot of harm in the ways they "help" other people with their computer problems. Now that we're trying to get everyone online, I thought it might be helpful to write down everything I've been taught about helping people use computers.
  • The AutoRun function in Windows can launch installers and other programs automatically when you insert a CD or flash drive, but this convenience poses a serious security risk.

    Unfortunately, simply turning off AutoPlay, a separate feature, isn't enough to prevent AutoRun from introducing a rogue program into your system.

  • When you start Cinelerra for the first time you should see four windows. The Program window at the bottom of the screen shows the timeline, with video and audio tracks. Time runs along the horizontal axis. Above this on the left is the Compositor window. In this window your masterpeice will take shape. To the right is the Viewer window. This is used for viewing clips and selecting which parts of the clips to put into your video. Finally on the bottom right is the Resources window. This shows all the original clips you have imported in, as well as resources like audio and video effects which are available to be used.
  • Unleash the 50,000 watt flamethrower of content creation in your UNIX box. Cinelerra does primarily 3 things: capturing, compositing, and editing audio and video with sample level accuracy. It's a movie studio in a box.
  • A software application which handles the editing of video sequences on a computer is called video editing software. It can also handle limited editing of the audio clips which accompany the video or at least the ability to sync the audio with the video.
  • While digital video editing today is an affordable, popular activity for both the computer hobbyist and amateur cinematographer, many people seem to think that video creation under Linux is either impossible or too difficult for the average computer user. Not so! From video capture to editing to DVD authoring and encoding, you can create high-quality videos easily with free, open source software.
  • Show hidden files and folders not working – after virus attack (heap41a svchost.exe)
    (tags: windows virus fix)
  • So, is Brain Workshop better than other brain training programs? The research that has been done suggests that it is better at actually improving your intelligence. That is a good thing. However, it is not as fun to play in my opinion as other brain games. So which is better? The exercise you actually do because it's fun? Or the exercise that is better for you, but which you don't play as much?
