Spring Europen 2013

This Monday I was the first time guest and speaker at (contrary to it’s name) local Czech conference Europen. It was interesting experience. And I would like to share a bit of what I experienced. What made it different from conferences I usually speak at was the audience. Not many Linux guys and quite some …

4 Conferences in October in Prague

There will be a lot going on in fall this year in Prague. There will be awesome cluster of four conferences! And as I’m somehow involved in all of them, I want to promote them a little bit as well. So what’s going on? There is openSUSE Conference coming to Prague. We were planning where to have it, how to do it and stuff like that. During the planning of this one and one new Czech one called LinuxDays, I took Jos with me to the LinuxDays conference meeting so we can discuss how can both conferences help each other. Meeting was really great and we ended up with deciding to merge both conferences! Have them both at the same time, same place and make them both even more awesome! We also had Theo with us, who was by that time thinking about organizing new conference for Gentoo people. So we throw in another conference! What is the result? During weekend from 20th October to 21st October, we will have four conferences at the same place! Gentoo miniconf, LinuxDays, openSUSE Conference and SUSE Labs conference! And the openSUSE/SUSE Labs one will continue even for two extra days ;-) I’m really looking forward to it, to see all these communities merge. And to have a lot of fun, on this surely awesome multiconference! We even have a common poster and landing page as you can see bellow ;-)

And why am I writing about it just now? Well, I was ill last week, working on getting better, but mainly because CfPs opens up today!!! So you can start submitting your talks/workshops! Here are links for all of them – directly to CfP page, but I would recommend to go through the longer way and checkout the respective websites as well ;-)

Help me polish MySQL in openSUSE 12.2

Categories:

April 14, 2012

"We can do it!" by workerIf you are following news regarding openSUSE and MySQL, you probably already know, that we have both MySQL and MariaDB in openSUSE to allow users to choose what they want to use. And if these two options are not enough, we’ve got server:database repository with newest and greatest development versions of both and MySQL Cluster on to of that. I think all this is great and awesome, that we have all of that.

Now to the not so great part. Unfortunately I’m bare human, I have to eat, sleep and I have some work, some bugs that takes a lot more time that I expected, some school duties to take care of and of course openSUSE Conference to organize! So as a result of all that, I can’t polish MySQL and MariaDB as much I would love to. And on top of that, I’m not expert in MySQL configuration. Part of that is that it just works and I never had any server where MySQL was slowing things down. But there is plenty of skilled MySQL administrators out there in community! So I’m calling out for help. You skilled MySQL admins probably have a lot of interesting tweaks you are applying to default configuration file. So take a look at them and think what could be useful for everybody, not just in your specific use-case. And either send me snippet with short explanation in the comments, or create .cnf file add it to the flavor directory and send me pull request on github! I’ll keep credits and your explanation of the snippet inside, so people will know, who came with this cool option and what does it do ;-)

Oh, and don’t get discouraged if I don’t include it right away, it may take me some time to get to it, but I’ll appreciate every suggestion ;-)

Some news about MySQL in obs

MariaDB logoIf you follow MySQL community at least as much as I do (browsing trough the planet from time to time), you know that some exciting milestones were reached both in Oracles MySQL and in MariaDB. And as I love bleeding edge software, you can try all these exciting things prepackaged in openSUSE ;-)

Oracles MySQL

Let’s start with news from guys at Oracle. Recently they released new MySQL Cluster 7.2. Yes 7.2 is GA now. And you can find a lot of exiting info online about how fast it is! If you don’t believe benchmarks done by others, try it by yourself! We have it in server:database repository for all supported openSUSE versions, SLE and few other rpm based distributions. Just add the repository and install package mysql-cluster_72. Pretty easy, isn’t it? ;-) So if you have MySQL cluster and want to take advantage of the latest improvements, give it a try ;-)

MariaDB

Now a some information regarding MariaDB. Folks at Monty Program were not sleeping either. They released release candidate of MariaDB 5.3, progressing towards GA and yesterday they released first alpha of MariaDB 5.5.20 – merge between their 5.3 and MySQL 5.5. Everything is packaged and ready for you to try in server:database ;-) But let’s speak a little bit more about MariaDB…

MariaDB 5.3 series

MariaDB 5.3 is currently in version 5.3.4 and is considered release candidate. It is around for quite some time already. It contains many improvements and people are doing benchmarks and are excited about changes. And it’s getting closer and closer towards GA. I asked on #mariadb channel and was told that GA is probably just a few weeks away. So here comes what I plan to do. openSUSE already contains MariaDB and we have MySQL Community Server as default. Therefore I’ll put MariaDB 5.3 into openSUSE 12.2 (next planned release). I’m running it for quite some time on this server and I haven’t lost any data. Looks quite stable and if somebody think that is still too new and untested, he can always use MySQL Community Server. If you have any objections, comments are lower on this page ;-)

MariaDB 5.5

Other think I would like to speak about a little bit is MariaDB 5.5.20. First alpha was released yesterday. What is so interesting about this release? It is merge of MySQL 5.5 and MariaDB 5.3 so it should contain goodies from both words! Ok, some things from MySQL 5.6 are still missing, but anyway, sounds promising. Although I have really low traffic website I switched today in the morning to this version, just to test that everything works fine and to encounter possible troubles sooner. If you want to try it, just add server:database repository and install package mariadb_55. That’s all and you can start testing new version and reporting bugs (preferably directly upstream ;-) )

KDE 4.8 release party

February 27, 2012

Minulý pátek se v Praze odehrála KDE 4.8 release party. Chvilku nám trvalo ji zorganizovat, ale nakonec přecijen proběhla. Pro ty, se co nemohli osobně dostavit, malé ohlédnutí se (s fotkami, ale už bez dortu, ten už není).

[mj-google-slideshow feed_url="https://picasaweb.google.com/data/feed/base/user/113898425601074911439/albumid/5713780999725380401?alt=rss&kind=photo&authkey=Gv1sRgCLzh_Jqp7_SU6AE&hl=en_US" width="400" height="400" classname="aligncenter" link_target="google.feeds.LINK_TARGET_BLANK" /]

I když se party odehrávala v Praze, kupodivu byla většina přednášek v angličtině a angličtinu bylo slyšet i mez přednáškami. Jakto? Většina našich přednášejících neuměla česky (alespoň prozatím ne). Theo, který party organizoval a zařizoval vše důležité, dokázal na party přilákat i známé zahraniční hosty. Do prahy přijel na party Cornelius Schumacher a Jos Poortvliet. Pokud se zajímate o KDE, určitě jste obě jména už slyšeli. Jos měl přednášku o patnácti novinkách v KDE (oslavující 15 let vývoje KDE) v pěti minutách. Nakonec přednáška trvala minut osum. Proč je dálka přednášky důležitá? Obecenstvo si mohlo tipnout, jak dlouho bude přednáška trvat a tři nejlepší tipy vyhráli plyšového geeka. Cornelius zase mluvil o historii KDE a jak se vyvynulo z projektu pár lidí v celosvětovou komunitu obsahující mnoho a mnoho lidí. Kromě návštěvníků ze zahraničí měl přednášku i Theo (tu jsem bohužel zmeškal jelikož jsem jezdil nahoru a dolu výtahem pro návštěvníky) a Tomáš Chvátal, který mluvil o překladech a o integraci LibreOffice do KDE.

Po přednáškách se Cornelius ujal krájení dortu a každý z návštěvníků mohl dostat kousek. Závěr párty byl tedy ve znamení pojídání KDE dortu, pití openSUSE piva a povídání si o opensource. Party se podle mně vyvedla, alespoň já jsem se dobře bavil i když KDE nepoužívám. Děkuji všem kdo se zúčastnili a těším se na příští setkání, které bude vlastně už tento víkend.

PS: Pokud si chcete KDE 4.8 sami vyzkoušet, nějaká média lze nalézt v SUSE Studiu nebo si můžete počkat na oficiální vydání Gentoo médií později tento týden.

KDE 4.8 Release party

February 27, 2012

Last week on Friday we had a KDE 4.8 release party in Prague. It took us some time to organize everything, but in the end everything went well. For those of you who missed the party, little overview (and some photos, sorry, no cake left).

[mj-google-slideshow feed_url="https://picasaweb.google.com/data/feed/base/user/113898425601074911439/albumid/5713780999725380401?alt=rss&kind=photo&authkey=Gv1sRgCLzh_Jqp7_SU6AE&hl=en_US" width="400" height="400" classname="aligncenter" link_target="google.feeds.LINK_TARGET_BLANK" /]

Even though it was a Prague release party, we spoke quite a lot in English as well. Why? Well most of our speakers don’t speak Czech (yet). Theo was one organizing the talks and inviting speakers and doing all important stuff around the party and he managed to get here Cornelius Schumacher and Jos Poortvliet to come. Both of them has a long history with KDE, so they were giving great talks. For example Jos spoke about 15 new KDE features in 5 minutes and Cornelius about how KDE evolved over the time from small project done by few people to the current state where many people from all over the world works on it. Talk by Jos was also important from other reaseon. People could bet how long will it take and three closest to the actual time have won plush geekos! In the end five minutes talk lasted eight minutes. Apart from famous foreign visitors, we had talks by Tomáš Chvátal about translations and LibreOffice KDE integration and Theo also had a talk which I unfortunatelly missed because I was fetching party attendees in the reception and getting them up through the lift.

After the talks, Cornelius started cutting the cake and serving it to all attendees and we talked and enjoyed the KDE cake and openSUSE beer and talked… I would say, party was great and even though I’m not a KDE user, I enjoyed it! Many thanks to everybody who participated and I’m looking forward to next open source event which happens to be this weekend :-D

PS: If you like to get your hands on KDE 4.8 Live media, you can find some in SUSE Studio or wait for official Gentoo Live media that will be released later this week.
