Let There Be Light: Promoting OpenOffice.org with Sun

Posted by Paul Verreth Wed, 14 Feb 2007 16:13:00 GMT

The OpenDocument Format (ODF) just keeps on getting stronger. It is now an official ISO standard; there are numerous applications that support it, with varying degrees of fidelity, including Google’s online word processor and spreadsheet; there’s an official Microsoft-funded plug-in for Microsoft Office that allows it to open and save ODF files, and a program that converts between ODF and the Chinese UOF XML office format; and the ODF community has largely sorted out issues of accessibility that threatened to de-rail its adoption by Massachusetts.

At the same time, Microsoft is clearly beginning to feel the pressure. Its attempts to ram its own XML format through as an ISO standard, and the unseemly haste with which its 6000 pages of documentation were approved as an ECMA standard, are an indication that it is playing catch-up in this sector, even if it remains the dominant player.

EasyUbuntu

Posted by Paul Verreth Sun, 11 Feb 2007 13:09:00 GMT

EasyUbuntu is an easy to use (duh!) script that gives the Ubuntu user the most commonly requested apps, codecs, and tweaks that are not found in the base distribution – all with a few clicks of your mouse.

EasyUbuntu is so easy to use in fact, that even your grandma could be playing encrypted dvds, streaming Windows Media, and sporting the latest Nvidia or Ati drivers in minutes! And yes, EasyUbuntu is GPL.

EasyUbuntu works on (X/K)ubuntu and on all the three architectures (x86, AMD64 and PPC).

Thunderbird: instellen van de voorkeurbrowser

Posted by Paul Verreth Wed, 07 Feb 2007 08:48:00 GMT

Soms is het niet mogelijk om op niveau van het OS, de voorkeur browser in te stellen.

Hier is een methode om de voorkeurbrowser in te stellen voor Thunderbird, zodat die dan gebruikt zal worden bij het klikken op een link in een mailbericht.

In de prefs.js van Thunderbird, die zich bevind in een directory zoals $HOME/.mozilla-thunderbird/d5bnqttu.default kan je volgende lijn bijvoegen:

user_pref("network.protocol-handler.app.http", "firefox");

Opgelet: Enkel doen wanneer Thunderbird niet actief is, want anders wordt prefs.js toch terug overschreven.

convert een.png -thumbnail 500x500 een-thumb.png

Dit maakt van een png van 778×605 een thumbnail die past binnen een box van 500×500. De grootte van deze thumbnail is dan 500×389.
