Kernel Log: Ceph file system in 2.6.34, kernel and KVM presentations at the CLT2010

Filed under
Linux

Linus Torvalds has integrated the Ceph distributed network file system and released the second release candidate of 2.6.34. Torvalds intends to vary the length of the merge window from now on. Slides of the presentations at the Chemnitz Linux Days provide background information about kernel and KVM topics. Ubuntu has been given an AMD graphics driver which cooperates with series 1.7 X Servers.

When he released the first RC of 2.6.34 early, which surprised many subsystem maintainers, Linus Torvalds announced that he might still integrate the Ceph distributed network file system, which didn't make it into 2.6.33, although the merge window had already closed. He did this last weekend and, shortly afterwards, released Linux 2.6.24-rc2 – the usual release email for the new version has not so far appeared on the LKML.

Licensed under the LGPL, Ceph is a "Distributed Network File System" which, according to the developers, can manage data on a petabyte scale "and beyond", it is robust and offers numerous functions that are missing in other similar open source file systems. Detailed information about Ceph is available on the project's homepage, in a short description which was integrated into the kernel sources together with the file system code, and in an older article on LWN.net which describes an earlier, Fuse-based version of the file system.

Red Hat CTO unexpectedly quits, amid rumors of executive 'friction'

No-one among the rank and file at Red Hat seem to have seen this coming. In a move the Linux giant's staffers said was "shocking" and a "punch in the gut," long-time Red Hat chief technology officer Brian Stevens has resigned. In a short press release, the company announced: "Brian Stevens will step down as CTO." In the same release, Red Hat's president and chief executive Jim Whitehurst said, "We want to thank Brian for his years of service and numerous contributions to Red Hat’s business. We wish him well in his future endeavors." Read more

Is Microsoft engaging in digital imperialism?

Windows, the common carrier of Microsoft, is such a sordid mess that it suffers regular glitches and conducts mass surveillance on users. Microsoft knows that without Windows it cannot survive, so dirty tricks resume in a very big way. This is not a beep on the radar but somewhat of a surge. Nothing is going to change in Munich, but Microsoft is trying to maintain an international/universal perception that the migration to GNU/Linux was a disaster. Numerous anonymous blogs were created to attack Munich over this and provocateurs of Microsoft loved citing them, only to be repeatedly proven wrong. Microsoft is trying to make an example out of Munich in all sorts of nefarious ways. We need to defend Munich from this malicious assault by the convicted monopolist and corrupt enterprise that’s acting as though it fights for its very survival (while indeed laying off tens of thousands of employees).

Shortlist of open source software used at NASA lab

Yes! We use a lot of open source. The short list includes Python, GitHub, Processing, VLC, jQuery, D3.js, Blender, VRUI, ImageJ, VMD, ParaView, MeshLab, VNC, ImageMagick, SWIG, Emacs, and many more. We like using open source because it gives us more flexibility because of licensing and allows us the opportunity to contribute back to the community using our expertise. Our favorite open source project that we work on is OpenMDAO. This project is run out of another Division at our Center. Our team provides some programming support. OpenMDAO is an open source Multidisciplinary Design Analysis and Optimization (MDAO) framework, written in Python. You can use it to develop an integrated analysis and design environment for your engineering challenges. Read more

GSoC: Thumping the Malaria and voyaging in cosmos with KStars

Let's talk about my project now. KStars is desktop planetarium application under KDE Education Projects. I developed QML based cool interface to enable users to browse through image database of community of astrophotographers (i.e. astrobin.com) which contains more than 1,20,000 (number is increasing everyday) real time and very high resolution images along with various information related to them (i.e. Date on which image was captured, Bortle Dark-Sky Scale, RA Centre, DEC Centre, Telescope or Camera used, Description added by astrophotographer etc). I am sure that this browser will enthrall school children by showing them real time images of stars and galaxies located at hundreds of light year far from earth. Read more
