Hurry up, submit a paper! The LinuxTag Call for Papers ends tomorrow, February 16th.
Short info about LinuxTag from the homepage:
LinuxTag 2007 opens doors from May 30 to June 2, 2007 on Berlin Expo Center under the Funkturm. We invite users and experts to learn at Europe’s leading conference and expo more about the potential of Linux, Open Source, and Free Software.
FOSDEM, the Free and Open Source Software Developers' European Meeting will again take place in Brussels, Belgium on February, 24th & 25th. I went there last year and really had a great time. This year, I submitted a proposal for a lightning talk, which has been accepted! I've just been informed that the lightning talk schedule is now published. My talk "What's new at MySQL AB" will be on Saturday, at 17:00. I look forward to being there!
The following is what i wrote on “43people.com” about the boss. I thought it was worth keeping in my own archives, since it’s actually a story about my life as it pertains to Mr. Bezos.
Back a few years ago, I was taking some classes down in Edmonds.
The one I’m thinking of in particular was on the care and feeding
of unix. We were using red hat linux 6.0 or some crufty version
that wasn’t so crufty at the time.
Anyway, the prof didn’t require that we buy any books, but he made some suggestions. And he also suggested that we buy them on this new fangled “Internet” thing through a few of his friends down south in Seattle at this place called Amazon.com.
And thus was my introduction to O’Reilly and Associates. I soon thereafter bought a book called “ …
[Read more]I am happy to announce version 0.4 of mylvmbackup, a tool to perform consistent backups of a MySQL server's tables using Linux LVM snapshots.
For this release I'd like to especially thank Robin H. Johnson from the Gentoo project, who contributed another batch of useful changes and informed me that mylvmbackup is now in productive use to perform backups of the MySQL databases that power the project's Bugzilla bug tracking system. I am always glad to read about such use cases - how do you utilize mylvmbackup in your environment?
Now that the source tree for the new Falcon Storage Engine is finally public, here's a quick HOWTO on how to compile the server from source. This procedure is described in more detail in the MySQL Manual. I assume you use Linux and have the required development toolchain installed.
You first should get the free BK client from http://www.bitmover.com/bk-client2.0.shar, unpack and install it:
$ wget http://www.bitmover.com/bk-client2.0.shar --17:34:34-- …[Read more]

Everyone has heard of being slashdotted or maybe dugg. But have you ever been Yahoo!ed?
Phones started beeping, mayhem ensued. The first thing we looked at was the database. Is some MyISAM table locked? Is there a hung log processor running? The database was busy, but it looked odd. The web servers were going nuts.
As we soon discoverd, we (dealnews.com) were mentioned in an article on Yahoo!. At 5Pm Eastern, that article made it to be the featured article on the Yahoo! front page. It was there for an hour. We went from our already high Christmas traffic of about 80 req/s for pages and 200 req/s for images to a 130 req/s for pages and 500 req/s for images. We survived with a little tinkering. We have been working on a …

Recently I stumbled over a posting on the German MySQL Forum from a user
that accidentally removed all table files from a MySQL Server's
data directory with a misbehaving shell script. He was surprised
to find out that the server happily continued to serve requests
and his web site was still fully operational, even though
/var/lib/mysql/<database> was completely emtpy! The reason
for this in a nutshell: the rm command only removed the reference
to the table files from the database directory, the files itself
were not removed from the file system yet as the mysqld process
still had the files opened. So as long as a process keeps a file
open, the kernel will not release the disk space occupied by the
file and it will remain intact, albeit no longer visible.
Of course, the user was now desperate to recover the deleted
tables files and was …

Few days ago I’ve started migration of some of my non-critical servers to Debian Etch (from Sarge). Just after first apt-get update && apt-get dist-upgrade, when apt has been upgraded, I noticed really strange (as for me) error: when I’ve tried to do “apt-get update” it worked fine, but there was annoying message like following:
# apt-get update
......
Fetched 5562B in 13s (421B/s)
Reading package lists... Done
W: There are no public key available for the following key
IDs:
A70DAF536070D3A1
W: You may want to run apt-get update to correct these
problems

UPDATE: Thanks to Kurt Fitzner we know, that:
There is already a mechanism to do this automatically:
$ apt-key update
This will obtain the necesary keys and import them. No need to go through gpg directly.
After not so …
