[Read more]Interview mit Lukas und mir auf der DevOpsCon 2015 in Berlin, kurz nach dem Talk über Private Cloud mit OpenSource.
Auf der FrOSCon 10 in St. Augustin habe ich kürzlich ein Update zu unseren Erfahrungen mit dem Thema "Private Cloud mit OpenSource" gegeben. Leider sind noch nicht alle Probleme, über die letztes Jahr berichtet wurde, behoben, aber wir sind schon ein gutes Stück weiter und haben neue Stolperfallen gefunden und z. T. auch überwunden.
Leider habe ich mich mit der Zeit ein wenig getäuscht, da ich den Talk vorher schon einmal in gekürzter Form in 40 Minuten unterbringen musste, aber in der Präsentation den Countdown für die FrOSCon wieder auf 60 Minuten zu stellen vergessen hatte. Zwischenzeitlich war ich deswegen der Meinung, ziemlich hinterherzuhängen... Hoffe, es macht trotzdem ein bisschen Spaß, so blieb am Ende mehr Zeit für Fragen und Gespräche :)

[Read more]At Percona Live MySQL Conference 2015 next week I’ll be presenting on “Towards One MILLION queries per second” on 14th April at 4:50pm in Ballroom A.
This is the story of work I’ve been doing to get MySQL executing ONE MILLION SQL queries per second. It involves tales of MySQL, tales of the POWER8 Processor and a general amount of fun in extracting huge amounts of performance.
As I speak, I’m working on some even more impressive benchmark results! New hardware, new MySQL versions and really breaking news on MySQL scalability.
In MySQL Character encoding – part 1 we stated that the myriad of ways in which character encoding can be controlled can lead to many situations where your data may not be available as expected.
UTF8 was designed on a placemat in a New Jersey diner one night in September or so 1992.
Setting MySQL Client and Server Character encoding.
Lets restart MySQL with the correct setting for our purpose, UTF8. Here we can see the setting in the MySQL configuration file, in this case /etc/mysql/my.cnf.

Breaking and unbreaking your data
Recently at FOSDEM, Maciej presented “Breaking and unbreaking your data”, a presentation about the potential problems you can incur regarding character encoding whilst working with MySQL. In short, there are a myriad of places where character encoding can be controlled, which gives ample opportunity for the system to break and for text to become unrecoverable.
The slides from the presentation are available on slideshare.
