According to Vint Cerf, vice-president of Google and the man dubbed “the godfather of the net”, Europe will run out of IPV4 addresses by mid 2011. It’s time to switch to IPV6.
IPv6 was developed by the Internet Engineering Task Force (IETF), and is described in Internet standard document RFC 2460, published in December 1998. It has the capacity to provide 3.4×1038 IP addresses (around 340 trillion, trillion, trillion), probably making NAT (Network Access Translation) something of the past.
Are network and system administrators ready for the change over? Are SMEs ready for the change over? It’s time for a bit more reading I guess.
OpenSuse 11.3 Mobile internet USB dongle problem

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?
Echofon shamefully drops Firefox for Linux

Echofon has officially announced it is dropping support for Custom build Firefox, so it will no longer work with “minor” platforms. How dare you Echofon!? This is such short sightedness.
Apparently the previous version (1.9.6.4) of the Echofon plugin to Firefox still works, but I would appreciate suggestions for a different Firefox plugin. I would be happy to ditch Echophon alltogether, it was a good product untill the developers killed it for me.
If you get the error - Echofon does not support this platform or custom build Firefox. (Can’t get OAuth signer.) / Cc['@naan.net/twitterfox-sign;1'] is undefined (Fx version 3.6.8 / ABI x86-gcc3) – according to the Echofon developers you are using a minor platform, and that includes 64bit build on Mac and Windows..
LinuxCon 2010 Just for Fun Poll Results explained

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
- 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 ]
- 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
- 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 ]
- Ceph Filesystem: Ceph is a distributed network file system designed to provide excellent performance, reliability, and scalability. [ extracted from http://ceph.newdream.net/about/ ]
