Qt Developer Days 2010

June 4th, 2010 by

Today I got a email about registration for “Qt Developer Days 2010”. This conference will be in Munich (October 11-13) and in San Francisco (November 1-3). I think this is the biggest and best Qt-event. Last time there was more than 700 people. It’s very interesting for me as the KDE developer, but it’s not free like FOSDEM or openSUSE Conference 🙁

For example, 3 days in Munich cost 499€ (if you pay befor 15th september and 699€ if you pay after). Ok, I know that Qt/Nokia makes very good coffee, but anyway this event is very costly for students like me 😉

I will wait for the openSUSE Conference and meet the Qt/KDE hackers there.

Guest Blog: Rares Aioanei – Weekly Review of the PostgreSQL Project with openSUSE flavor

June 4th, 2010 by

Hello all, and welcome to this week’s edition of the PostgreSQL Weekly News, openSUSE-style!

As accustomed, we’ll start with news picked from the mailing lists, then we’ll move on with news from the PostgreSQL Planet. Here we go…

-We start off this week with Mark Hills’ announcement of the release of pgnotifyd, which,  if we listen to Mark, ” connects to a PostgreSQL database, listening for the named  asynchronous notification. When notification is received it executes the given command.

It is typically a cleaner and more efficent alternative to polling a PostgreSQL database for changes (using a crontab(5) or similar.)

I’ve been using it successfully to synchronise passwords and mailing lists. This is an initial release in the hope others can benefit from it.”
You can find out more here : http://www.pogo.org.uk/~mark/pgnotifyd/ .

-Oleg Bartunov announced he posted pictures from PgCon 2010; you can watch here : http://www.flickr.com/photos/obartunov/sets/72157624042768831/ .

-Giuseppe Maxia announced OpenSQL camp 2010; I will try to copy the most relevant stuff from his announcement, in order not to make this article too big :
“OpenSQL Camp is a free conference of, by, and for the open-source database community of users and developers. The OpenSQLCamp 2010, European Edition (http://opensqlcamp.org/) will take part in parallel to the Free and Open Source Conference 2010 (http://froscon.org/) on Saturday 21st and Sunday 22nd August in St. Augustin, Germany, which is located close to Bonn and Cologne.[…] We would like to invite your project to participate in this event.

We’ve set up a call for participation (http://opensqlcamp.org/Events/2010/Call_for_Participation) – the deadline for submitting your proposal is July 11th.

We are seeking talks related to Open Source Databases of all kind, not just relational databases! Submission about tools and technologies related to OSS databases (e.g. connectors/APIs) are also welcome.

Some ideas and for submissions:

* A how to presentation, showing how to solve a common problem in the database field.
* An introduction/overview about a certain database project/product or related tool
* Providing “best practices” information for administrators
* A deeply technical and developer-centric session about some project’s internals or an API used to connect to a database.

We look forward to your contribution! Please don’t hesitate to contact us via IRC (#opensqlcamp on FreeNode) or our Discussion Group (http://groups.google.com/group/opensqlcamp) ”

-Bruce Momijan announced the timetable for the release of 9.0, which would be as  follows : “Assuming we want a release Postgres 9.0 by mid-August, here is how the timetable would look:

Need RC release to be stable for 1-2 weeks before final
RC must be released by August 1
Beta must be stable for 2-3 weeks before RC
Stable beta must be released by early July

So, we have 5-6 weeks to get a stable beta.  Looking at the open issues: http://wiki.postgresql.org/wiki/PostgreSQL_9.0_Open_Items#Resolved_Issues

it looks like we are doing OK, but we must continue progressing.”

-The ChronicDB release team announced version 2.2.2 ; ChronicDB is a live DB schema update system, allowing DBAs to minimize the downtime of their servers. More on their website, http://chronicdb.com/

-On the Planet , we have Christophe Pettus posting his slides from the Open Bridge 2010 conference, called Introduction to PostgreSQL, here : http://thebuild.com/presentations/intro-to-postgresql-osb2010.pdf.

-The PostgreSQL Weekly News this week offers some local events info, as well as, as usual, the submitted patches list. Check out the news here : http://www.postgresql.org/community/weeklynews/pwn20100531.

There you go, this was the news this week. Enjoy your weekend.

Guest Blog: Rares Aioanei – Weekly Kernel review with openSUSE Flavor

June 4th, 2010 by

Hello, everyone, and welcome!

This week sees the release of 2.6.35-rc1,  plus other kernel-related news, so let’s start.

-Along with tree updates/patches/fixes for the usually/most updated trees,  such as perf, x86, tracing or infiniband, for example, Linus Torvalds announced the release of 2.6.35-rc1 : “It’s been two weeks, and so the merge window is closed. There may be a few trees I haven’t pulled yet, but the bulk should all be there. And please, let’s try to make the merge window mean something this time – don’t send  me any new pull request unless they are for real regressions or for major bugs, ok?

This time, there are no new filesystems (surprise surprise), but there’s certainly been filesystem work both on an individual FS layer (btrfs, cept, cifs, ext4, nfs, ocfs2 and xfs) and at the VFS layer (superblock
and quota cleanups in particular).

But as usual, the bulk of the changes are in drivers. About two thirds of all the changes, to be exact. infiniband, networking and staging drivers are the bulk of it, but there’s changes all over (drm, sound, media, usb,
input layer, you name it).

And what’s good to see is that we continue to have very healthy statistics. About 8500 commits (of which 400+ are merges), with about a thousand individual developers involved (git counts 1047, but some of them are bound to be duplicates due to people mis-spelling their names etc).
It’s skewed, of course – with the median number of commits per person being just three – but I think that’s what we want to see in a healthy development environment.

Linus

-Greg Kroah-Hartman announced 2.6.32.15, and his description says much in very few words : “It reverts two patches that were previously applied that shouldn’t have been in the .32 kernel series.  If you don’t have any problems with the 2.6.34.14 kernel, there’s no need to upgrade to this release.”

-The H Online has an interesting article named “Kernel Log: Linux 2.6.35 taking shape”. In a few words, the article is about “Linux 2.6.35 will deliver better network throughput,  support the Turbo Core functionality offered by the latest AMD processors and de-fragment memory as required. On LKML, a discussion on merging several patches developed by Google for Android is  generating large volumes of email.” Have a read here : http://www.h-online.com/open/features/Kernel-Log-Linux-2-6-35-taking-shape-1012850.html if you’re interested.

-Eric Anholt came up with improvements and fixes in the drm-intel tree destined for -rc1, including h264 acceleration for Ironlake hardware, Benjamin Herrenschmidt updated the powerpc tree, Konrad Rzeszutek Wilk added some features to the iBFT tree for -rc1, Jeff Garzik had some minor fixes for the libata-dev tree and Arnaldo Carvalho de Melo posted a series of improvements for the perf tree targeted at 2.6.36.

-Jeffrey Merkey announced the Cworthy libraries for Linux kernel utils : “I created a cworthy library under ncurses for xterm and linux terminals (also works on DOS and Windows too) years back and have ported it to .so an .a formats.  Looks like the old NetWare inderface and runs on Linux terminals.  Wrote a sample IFCONFIG lookalike with the cworthy look alike portal manager that displays the same info as IFCONFIG.  May be of use and looks a lot better than the command line. It is not the actual cworthy but recreates the same look and feel and supports all the colors you would want with all the fancy menu and screen functions.  I donate it to make the kernel utils look better and make me feel more at home since NetWare is no more.  I use this lib in most of my projects and it was included in the old NWFS but was not cleaned up and broken out.  I pthread enabled it and also added support for most of the terminals our there (ANSI and dumb not supported but the rest are).”

-Speaking of the perf tree, Frederic Weisbecker and Ingo Molnar also posted fixes in this area, while Paul Mundt updated the sh tree for -rc2; Steven Rostedt posted a fix related to tracing, Dmitry Torokhov updated the input tree for -rc1 and Robert Richter fixed crashes and other improvements in the oprofile tree.

This concludes this week’s Weekly Kernel News. Have a lot of fun.
