  • Getting the OS

    First go to http://www.ubuntu.com and get the latest version you're interesting in. They offer server version that they support for 5 years or so. I suggest one of those if you want to run a server. This is an ISO, in generate around 600Mb so be ready to wait a few hours... Even with a really fast connection, because the transfer will be limited by the mirror in most cases.

    WARNING
    Unless you know better, I strongly suggest you get the Ubuntu Server version. Maybe a bit more annoying to use BUT it works on ALL computers. And ...
  • History

    Today I finally noticed that the W3C validator was open source (some people are real slow!)

    This means I can get the source and run that validator on my system! Cool!

    Under Debian you can just download the package with:

       apt-get install w3c-markup-validator

    The will properly install the module, however, it won't be recognized just as is. I had to do several things to get things to mostly work...

    Domain

    If you want to use a specific domain name, you will need to edit your bind configuration file and add it.

    Apache

    Now, Apache is seemingly setup properly to ...

  • Preparations after unzip

    Installing SugarCRM is generally easy, but if you don't want to just make everything writable by Apache, you may find it tricky, especially if you have problems setting up the system.

    First of all, you want to get the code from SourceForget.net and extract it in the root directory of the website where you want to use it. I prefer to dedicate a sub-domain name such as crm.m2osw.com to make use of SugarCRM. That way I don't have to deal with other weird things of using this under a sub-directory.

    Once in there, the user and group should be a user other than ...

  • The other day, I wrote a module for Drupal. Up to here, no problem. What I wrote required a small amount of Javascript to make a dropdown menu feature work. That worked just fine under Mozilla and FireFox, and even Safari & Konqueror.

    When I tried with Internet Explorer, nope. Not working at all.

    The function I was using goes like this:

  • Lately, I have been working on a website that has to work on all mordern browsers (in 2007). And I have had problems with Internet Explorer and Safari. Safari is more annoying because there are less hints on the Internet, but the solutions are still quite easy to find (it's not like it's all broken or something.)

  • Today we were forced to transfer all our services from one server to another.

    One of those services is Jira.

    From what I have seen, there is no good documentation on our to migrate an instance of Jira from one Ubuntu server to another. Yet it is actually not that complicated.

    Step 1. Make sure your current instance is not running

    In order to avoid changes that would not make it to the new instance, make sure to stop Jira in the existing system. If you can, just stop Apache2 or whatever front end you are using.

    Step 2. Copy the Data

    Jira saves data in two locations: your database ...

  • Today I installed a Joomla site because I have a contract to do some development in Joomla.

    So... I started, looks real nice and stuff, clicked next, next and got and error. It tells me that the configuration.php file is not writable and that I'll have to copy and paste once I'm finished or make it writable. Well... I thus copy configure.php-dist as configure.php and try again.

    That makes it fail a little later with the following error:

  • In the last few days I have been working on a small project to get a really nice form for one of my sites. The form uses a lot of JavaScript for all sorts of fancy things (such as check user input to make sure we don't accept total crap such as an empty entry or just "1" as a credit card number.)

    The information finds itself in an IFRAME, which was the easiest way to get the time to load at decent speed and  to better manage the form in a separate area and not the main landing page. This will make it easier to maintain the landing page itself.

    however, that created ...

  • Last night as I was compiling a new PECL extension for an install, after a while it worked... I could run php -v and it would give me the version of the PHP modules without telling me that the it couldn't load the extension (i.e. we already had the extension=http; in the php.ini file.)

    But when testing with php -v on the command line, it would reload the php.ini and apply the extension feature and such.

    However, when testing with Apache, it was still not working. The PECL installation was all correct, so why would it not see the resulting extensions?!

    Because you need to restart Apache. ...

  • If you are using Apache and e-Commerce, you probably want to know all the details of the ciphers used by the Apache SSL module.

    So listing Apache supported ciphers is done using nmap as follow:

    nmap --script ssl-cert,ssl-enum-ciphers -p 443 secure.m2osw.com

    This call gives you a complete list of all the ciphers currently accepted by your running version of Apache. For example, the list may look like this:

    | ssl-enum-ciphers:
    |   SSLv3:
    |     ciphers:
    |       TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA - strong
    |       TLS_DHE_RSA_WITH_AES_128_CBC_SHA - strong
    |       ...
