KDE - Authors //Promoting book writing in KDE

If you are in any way related to KDE even if you are just a user and think you can/want to help/join us then without giving a second thought fire an email to me. (supreetpal@gmail.com)




How it all began . .


Last October, Google invited proposals for a GSOC Doc Camp Sprint. The sprint was organised at their offices in Mountain View, California and luckily a team of KDE-Contributors got their proposal selected (I was one of them). Over there, we were teamed up with independent volunteers who were basically professional editors and were briefed about the whole plan. The layout was simple, we had to spend the first few hours outlining the chapters and target audience for our book, then spend the rest of the sprint working on the content. We had proposed to work on a beginner’s guide to KDE development, for developers. Most of the content required by us was available on the wiki but writing a book is a totally different approach than writing a wiki. Working 12+ hours a day , things were on w…

Nouveau - Summer Project

Implementing a software scripting engine on Fermi to achieve safe memory re-clocking.

Fermi stands for Nvidia GPUs based on Fermi architecture.

NVidia cards have long had the possibility to reclock at least some of the engines of its GPUs. Up to the geforce 7 (included), reclocking used to happen at boot time and usually didn't involve memory reclocking at all.

It changed with geforce 8 (nv50) where almost all laptops got the capability to reclock both the VRAM and the main engines. This was introduced in order to lower power consumption when the GPU was mostly idle. The default boot clocks were usually in some intermediate state between the slowest and the fastest clocks. The reclocking process for these cards is mostly understood and Nouveau is not far from being safely reclock on the fly, even while gaming.

Geforce 200 (nva3) introduced load-based reclocking on all the cards. This started being a real problem because the default boot clocks are a third to a half of the maximum …
