Page list for Linux

  • Today I got a really strange error. Part of the message was:

    E: Encountered a section with no Package: header
    E: Problem with MergeList /var/lib/apt/lists/<some name>
    E: The package lists or status file could not be parsed or opened.

    That seemed really bizarre. I had never seen such an error before...

    So I searched for it and one thing to know is that the files under that directory are temporary, so you can actually delete them. apt-get knows how to regenerate them.

    So in other words you can do something like this:

    sudo rm /var/lib/apt/lists/<some file>
    # or ...
  • WARNING: This is actually wrong. The -F is a SEARCH feature. Not a way to recalculate the value on your own system. So you can verify that the value is the same in your database, but SSH already does that and shows you that terrible warning... so in effect it is the exact same command.

    Whenever you connect to a computer with SSH, it gives you a fingerprint of the host.

    Ever wondered how to check whether that fingerprint is a match? Yeah... I figured, 99% of us don't even know how to make sure that it is indeed a match.

    There is the command line to generate that fingerprint:

  • Got to setup a new server and first got the firewall to where I wanted it to be:

    • Block everything except ssh, Apache, SMTP, a few other things, but really not much more than that.
    • Block everything with IPv6 since we don't use it.

    Then I installed Apache and a couple of websites.

    The first one finally started to work, but it was so very slow to show up. I checked the code, the database, nothing wrong... And the database is lightning fast! ( in comparison to our previous server that is.)

    So I wondered and thought maybe that my Apache firewall is in the way. I turned it ...

  • Noticed today that I had an easy to use facebook URL. It goes like this:

    So, the Facebook URL followed by my first and last name. Easy, hey?

    Another important thing, in your facebook privacy settings, make sure you select the necessary flags so people can see your page! If you make yourself totally private people won't find you and won't be able to see your page!

    You can also let Google, Yahoo!, MSN Live find your profile!

    Sample of where you need to click to get at the right place in Facebook:

    Settings and Privacy Flags to change to make sure people find you!

    It seems this should work with tools and ...

  • The attached package currently includes a C function and a SIMD function that both are used to blend two images together.

    At this point I do not like the fact that the result is invalid (1 off with large values—if you have an alpha of 255, then you are likely to get the source component value minus 1). Outside of that, it works nicely and it is VERY fast.

    I can blend 3,300 NTSC images per second with my i5 (Intel(R) Core(TM) i5 CPU 760 @ 2.80GHz.) With my newer computers I can run 3,750 NTSC images per second. These have Xeon processors (Intel(R) Xeon(R) CPU E31220 @ 3.10GHz.) The ...

  • Have you seen animated icons in your tabs? This has been working for a while, with IE and FF and Co.

    All you have to do is create an animated GIF file as your "favicon.ico", and it is better to name it .gif, by the way.

    Because icons can now be pretty much any image format, not just .ico

    And if you need some favicon for your site, check this one out:

    Many of these are free!

  • Introduction

    The Qt library version can be retrieved in all sorts of ways. There are a few I use:

    Command Line Version

    The Qt tools will display the version. One of the simplest way is to use qmake as in:

    qmake --version

    It will tell you which version of the Qt library it is using.

    When writing a configuration script, you most certainly want to make use of the pkg-config tool (at least under Linux and Cygwin):

    pkg-config --modversion QtCore

    The result is just the version of the specified module. To find all the available module look in the ...

  • I create this page to talk about the work I've done to create a small Flash animation (under 1Kb) used to play a stream of audio (most specifically, from the radio Hotmix 106.)
