100 € Laptop für jeden

Bei Golem und Heise ist zu lesen, dass man unter
http://www.xogiving.org/
(momentan leider wegen Überlastung down) ab 12.11.2007 einen der Laptop kaufen kann. Leider(?) nicht für die angekündigten (und mehr als nur einmal revidierten) 100$ sondern für voraussichtlich 399$. Damit kauf man jedoch gleich einen 2. Laptop, der als Spende weitergereicht wird.

Für jeden, der nicht viel mehr als eine tragbare Schreibmaschine baucht, wäre dies vielleicht eine gute Idee um etwas gutes zu tun. (und wer sich eh n Laptop für 1500€ kauft, der kann ja auch so die 200€ spenden, da kommt es ja nicht mehr darauf an, oder? ;)

Danke an das MAKE Blog, dadurch bin ich gerade über William Kamkwamba Windmühlenblog gestolpert.

Ich bin auch, die von MAKE, einfach mal so frech und kopiere einen Teil aus seinem ersten Blogeintrag, ich denke, es ist eine gute Zusammenfassung, um was es eigentlich geht.

Our family is poor like many families in Malawi and Africa, and as a result, we have no electricity in our village or my home. For many years we had only paraffin candles to light my home at night. They are expensive, smoky, smelly and have to be purchased about 8 km from home.

During that time I decided to try to get as much education as possible by reading as many books as I could find. An organization called the Malawian Teacher Training Activity (MTTA), a project of USAID contributed a large quantity of books to the primary school library near my home. I read many of them. One of the books I read was called Using Energy, a primary school textbook about how energy is made. Inside the book there were plans for a windmill. I decided to build a windmill to provide power for my family.

Es scheint, dass Bücher wirklich die bessere Entwicklungshilfe sind.

Wikipedia: Automatisiertes Vertrauen

Beim UC Santa Cruz gibt es gerade ein Forschungsprojekt, welches eine Analyse erstellen will, wie sehr einzelne Bereiche eines Textes in der Wikipedia vertrauenswürdig sind. Dazu werden Textbereiche, die von “fragwürdigen” Editoren stammen farblich unterlegt. Je mehr Farbe, desto vorsichtiger sollte man mit den Text umgehen.

Natürlich handelt es sich dabei auch nur um ein Hilfsmittel. Wenn ein Dr. Dr. Dr. Müller als erstes einen neuen Artikel einstellt und er vorher noch nie was in der Wikipedia gemacht hat, wird der Artikel komplett eingefärbt sein, egal wie gut der Artikel ist. Solche Fälle sind inzwischen in den größeren Sprachversionen (Englisch, Deutsch, Fanzösisch, Polnisch) eher eine Seltenheit.

Im Moment gibt es leider nur ein paar hundert Seiten, die bearbeitet wurden und ein Einbau in die Wikipedia selbst ist wegen der wahrscheinlich ziemlich hohen Last für die Rechner doch unwahrscheinlich. Aber vielleicht wird man ja bald zumindest als Administrator so ein Tool zur Verfügung haben, wenn die lange angekündigte stabile Versionen mal endlich da sind.

Clocking In And Out Of Gene Expression

http://www.bio.com/newsfeatures/newsfeatures_research.jhtml?cid=30100025

A chemical signal acts as time clock in the expression of genes
controlled by a master gene called a coactivator. Using steroid receptor
coactivator-3 (SRC-3), it was demonstrated that activation requires
addition of a phosphate molecule to the protein at one spot and addition
of an ubiquitin molecule at another point. Each time the message of the
gene is transcribed into a protein, another ubiquitin molecule is
chained on. Five ubiquitins in the chain and the protein is
automatically destroyed.
