Woman Blames Dell and Ubuntu For Missing Online School Classes

Another clueless woman has claimed that Dell computer and Ubuntu Linux have kept her from going back to school via online classes. According to a story - a woman bought a Dell computer and realized she ordered it with the Ubuntu Operating System rather than MS-Windows. She tried to change OS to Windows but Dell refused. Her Verizon High-Speed Internet CD won't load, so she can't access the internet. She also can't install Microsoft Word, which she says is a requirement for MATC's online classes. As a result, with no internet and no Microsoft Word, Schubert dropped out of MATC's fall and spring semesters. The full story is here including followup.

Now, I've no idea about Verizon's modem and DSL connection but most A/DSL provider modem (router) comes with an Ethernet port. There is no need to use wizard or CD based installer. Other software such as MS-Word can be replaced with OO (I submitted all my school work using OO office writer and no one even noticed the difference... ). Further both Verizon and MATC ready to help:

Verizon says it will dispatch a technician to try to assist her accessing the internet without using the Windows-only installation disk.

MATC also says it promises to accept any of Schubert's papers or class documents using whatever software she has installed.

So what is the problem here?

Wikipedia Moving 400 Servers To Ubuntu Linux From Red Hat Linux

Wikipedia is ditching out a mix of Red Hat and Fedora for Ubuntu Linux. Wikipedia has 10 million articles in 250 languages and it is one of the 10 most visited websites in the world.

One of the reasons for this switch was that they did not want to pay Red Hat for support on their provided software solutions. Ubuntu Linux get updated frequently and nothing can beat apt package manger.

According to Vibber, CTO of the Wikimedia Foundation:

We had a mix of things: some Red Hat 9, some Fedora -- several different versions. The group used a custom-scripted installation procedure, but found that having a multitude of versions was more difficult to maintain for its small five-person IT staff around the world. The move to all-Ubuntu was primarily done with the goal of "making our own administration and maintenance simpler. We decided that we want to standardize on something.
