  • Sometimes you do strange stuff with your Linux PC.
    I did yesterday, when I was expirimenting with what would happen if I would chmod /usr/bin/chmod to 000. That gave me some problems :P.

    Luckaly I had an old (dutch) Linux magazine lying around, and there was the solution! Thanx to: Linux Magazine

    If the CHMOD program is not executable anymore, you should start it via the Linker.
    I do not know what it is, but it worked. If someone knows, then please comment :).

    Execute this command:

    sudo /lib/ /bin/chmod 755 /bin/chmod

    If you're on another distro that doesn't need sudo, then just su.

    This also works for other programs, just as long you know the original path to it… (/bin/rm xD)

    Edit: 777 edited to 755,
    Here is another solution thanks to: Rainer Weikusat
    perl -e 'chmod(0755, "/bin/chmod")'

  • Because on-line search databases typically contain only abstracts, it is vital to write a complete but concise description of your work to entice potential readers into obtaining a copy of the full paper. This article describes how to write a good computer architecture abstract for both conference and journal papers. Writers should follow a checklist consisting of: motivation, problem statement, approach, results, and conclusions. Following this checklist should increase the chance of people taking the time to obtain and read your complete paper.

  • This video tutorial will explain how to losslessly convert any video file format, including quicktime .mov, flash .flv files, open source .ogv, .mp4, .wmv, .asf and more. I show you how to install ffmpeg, check the formats and codecs available to you, convert a file to a new format (windows media and .asf in this example) without any loss in quality during the decoding and encoding process, and create and run a script file that will enable you to run a batch conversion on any number of files at the same time.
  • Much like a vernacular, the universe of UNIX tools changes almost perpetually. New tools crop up frequently, while others are eternally modernized and adapted to suit emerging best practices. Certain tools are used commonly; others are used more infrequently. Some tools are perennial; occasionally, some are obsoleted outright. To speak UNIX fluently, you have to keep up with the "lingo."
  • C# and Java are fairly similar languages. They are similar enough that projects, such as our Encog project, can be converted to C#. Yet they are different enough that this is not always a 100% straight forward process. Additionally, there are several considerations to take into account so that your Java program does not look like a "Java Program converted to C#". C# programs support unique indexing options, properties and many other features that are not available to Java programs. For a true translation, it is important to use these as well.
