OpenSuse 11.3 Mobile internet USB dongle problem

Posted by on September 29, 2010 No comments

Has anyone be experiencing problems with USB mobile broadband Dongles on OpenSuse 11.3? Once the device (Huawei E156) is inserted OpenSuse recognises it automatically but after a few minutes it drops the connection and the device is not able to connect again. 

The Network Manager drops the device from the list and then re-inserts it, but for some reason it disables the Mobile Broadband. Removing and re-inserting the device dos not resolve the issue. I used this device very often on OpenSuse 11.2 without any problem. 

Is anyone having a a similar problem? Does anyone have the solution?

LinuxCon 2010 Just for Fun Poll Results explained

Posted by on August 12, 2010 No comments

The results of the “Just for Fun” Poll  linux.com community have just been released.  You may be wondering what some of those weird names actually mean, so here goes a short guide for those, like myself, who are not up to date with it all.


Best new Kernel Feature

  1. Btrfs: is a new copy on write filesystem for Linux aimed at implementing advanced features while focusing on fault tolerance, repair and easy administration. Initially developed by Oracle, Btrfs is licensed under the GPL and open for contribution from anyone.

    Linux has a wealth of filesystems to choose from, but we are facing a number of challenges with scaling to the large storage subsystems that are becoming common in today’s data centers. Filesystems need to scale in their ability to address and manage large storage, and also in their ability to detect, repair and tolerate errors in the data stored on disk. [extracted from https://btrfs.wiki.kernel.org/index.php/Main_Page ]

  2. Dynamic Tracing: Dynamic event tracing is one of the newest feature on perf/ftrace. This allows users to dynamically add/remove additional trace-events with various arguments in the kernel. This feature consists of kprobe-based event tracer and ‘perf-probe’ user-space command which helps users to find probe points easily from source code by analyzing kernel debuginfo.  Extracted from http://events.linuxfoundation.org/lfcs2010/tracing
  3. LogFS: is a Linux log-structured and scalable flash filesystem, intended for use on large devices of flash memory. It is written by Jörn Engel and in part sponsored by the CE Linux Forum. [extracted from http://en.wikipedia.org/wiki/LogFS ]
  4. Ceph Filesystem: Ceph is a distributed network file system designed to provide excellent performance, reliability, and scalability. [ extracted from http://ceph.newdream.net/about/ ]

How software patent broke the system

Posted by on May 18, 2010 No comments

The issue of Software Patent has been around for a while, but unless you really  have the time and drive to try to understand all that is involved you will be left like most of us, just wondering. The guys at Patent Absurdity have made a great documentary about this issue.

Patent Absurdity explores the case of software patents and the history of judicial activism that led to their rise, and the harm being done to software developers and the wider economy. The film is based on a series of interviews conducted during the Supreme Court’s review of in re Bilski — a case that could have profound implications for the patenting of software. (extracted)

The whole documentary was made with free software.

  • Cinelerra for video editing
  • Audacity for audio editing
  • Inkscape, Python and Blender for animation
  • Ogg Theora and Ogg Vorbis codecs
  • Edited on GNU/Linux machines
