  • 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:

  • Use at your own risk! These are links to other pages outside of this website:

  • 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.)

  • Working on a PHP application setup, I stumble upon a problem. Going to the installation page, I got the dreadful error:


    You don't have permission to access <root-path>/admin/install on this server.

    Looking at the error logs, the only thing reported was:

    client denied by server configuration

    The fact is that Apache does not tell you which setting actually forbids the access. I guess that's because once it gets checked by Apache, it is a blend of all the settings and not a tree being followed.

    Looking a round, and since I already had that error not too long ...

  • Internet

    Inter-Network. The Internet was created at a University to attempt to connect computers between each others from "far away places" (i.e. two buildings in the same University). The main concept was to create a set of protocols to make the systems work. Namely, the SMTP, FTP and TELNET. Now we have many others such as the well known HTTP, which is based on the TELNET concept.

  • SQL

    SQL, or Structure Query Language, is a programming language used to manage data in a relational database system. It was made an ANSI standard in 1986.
