Back from openSUSE Asia Summit 2014

October 31st, 2014 by

Thanks to openSUSE TSP, this was my first ever participation in openSUSE event. I spent 15 days in China, traveling outside Beijing after the event, One word to define the experience  would be People, close second would be Food. In this trip I met some of the nicest, friendliest and most helpful people and had food I have never seen before or know the names of.

The summit venue was very impressive, and the event was well organized, there were wide range of topics in both Chinese and English, including mine on openSUSE Education project. What was really missing in the event were many participants. It was a pleasure meeting all the attending community members: Saurabh Sood, Max Lin, Max Huang, Fuminobu Takeyama, Richard Brown, Anja Stock, Raghu Nayyar, Alick Zhou, Qian Hong,  and all the magicians behind the curtains running the show: Sunny, Lance, Yifan et al.

UnReal World RPG and propiertary applications in linux ecosystem

October 24th, 2014 by

While ago new version 3.19 of UnReal World RPG was released. It was very smooth release in my part. Everything was working as expected. Packages were build to several platforms that were planned. Those platforms were Ubuntu 10.04, 12.04, 14.04 and openSUSE 12.2,12.3,13.1 all there packages build from openSUSE 13.1 base distribution. Nobody found nothing to complain about binary packages before someone launched them on Arch distribution. (more…)

Proprietary AMD/ATI Catalyst fglrx 14.9 (14.301.1001-1) rpm released

October 11th, 2014 by

As of October 11th, a bunch of new rpm for FGLRX has been released for openSUSE 11.4 to 13.1 including Tumbleweed.
a special patch has been added for supporting up to kernel 3.17

Installation / update

Please refer to the wiki page SDB:AMD_fgrlx_legacy

Notice radeon HD5xxx or above only

This release concern only owners of radeon HD5xxx or above.
For older gpu, the fglrx-legacy is still 13.1, and thus didn’t work with openSUSE 12.3 or above.
SDB:AMD_fgrlx_legacy
Beware of that, and prefer the free open-source radeon driver which came out of the box from your openSUSE distribution.
For 12.3 and especially 13.1 the free radeon often offer a better experience than the old fglrx-legacy, especially for HD2xxx-HD4xxx range.

openSUSE Factory / 13.2

Dear fellow, unfortunately an still open bug at AMD is not yet resolved to make FGLRX working under newer xorg version.
There’s also a re-organization of how xorg files will be placed in the file system. Once both of them will be fixed Sebastian will produce a newer script.
If those appear soon we perhaps will see rpm fglrx for 13.2.

Ruby: Do not use += in loops

October 8th, 2014 by

Hi,
My motivation for writing this blog post is to have one simple place where I can point everybody using += in a loop. I will describe here why it can kill the performance of any application or library and will also show some measurement to demonstrate it. (more…)
