Devops Needs Sushi

Mysql

Using broken development frameworks , or why we don't use Zurmo

People often wonder why DBA’s used to hate developers, and with DBA’s also the System Engineers,
(note that I just expanded devops by adding dba’s to the picture..)

So let me tell you a story ..

A couple of weeks ago one of our customers wanted to start experimenting with a new type of CRM. A gamified CRM.
Zurmo …

So we set this thing up in a dev environment and started playing with it , while at first it looks nice ..
the application actually felt pretty slow.. however given that is a low resource development environment we looked no further.

Gentwerpen Devops Meetup & Conference Season Update

A couple of us have been taking about it a lot already .. we wanted to host a one day #devops event in .be already last year.. then talks about starting a meetup group started again with @wonko_be but it was @fs111 pushing the final button and calling the rest of the .be community to order, we’ve set a date
and the first session will take place (agenda still needs to be detirmined)

Devops in Munich

Devopsdays Mountainview sold out in a short 3 hours .. but there’s other events that will breath devops this summer.
DrupalCon in Munich will be one of them ..

Some of you might have noticed that I`m cochairing the devops track for DrupalCon Munich,
The CFP is open till the 11th of this month and we are still actively looking for speakers.

We’re trying to bridge the gap between drupal developers and the people that put their code to production, at scale.
But also enhancing the knowledge of infrastructure components Drupal developers depend on.

At Fosdem

  • on Friday evening , apparently having a confirmed reservation in a resto is not enough to actually be welcome at that restaurant.
  • at DrupalDevdays, only 2 laptops were open during our presentation
  • at DrupalDevdays, almost nobody in the room was already using CI
  • at Fosdem , the parking lot is full before 11:30 on a saturday
  • at Fosdem , much less Macs than last years .
  • at Fosdem , way too much rooms are already at full capacity so you need to have 2-3 backup alternatives ..
  • at Fosdem , people expect me to be in certain rooms, at the same time
  • at Fosdem , even with too much rooms already full one still misses a bunch of interresting talks
  • at Fosdem , one doesn’t even realize friends are speaking there too ..
  • at Fosdem , Android is the standard …
  • at Fosdem , you are confronted with the fact you probably forgot more names of people than you remember ;(
  • at Fosdem , you are surrounded by famous open source people, that aren’t even on the schedule
  • at the MySQL Meetup Dinner, Monty brings Salmiakki
  • at Fosdem , you wonder how many other people have survived their 11th edition
  • at Fosdem , you can’t get into any devroom on sunday morning
  • at Fosdem , begging on Twitter to get in to a devroom from the other side of the door works (at least for me :))
  • at Fosdem , netbooks are much less popular as opposed to 2-3 years ago ..
  • after fosdem … you crash ..\

High Availability MySQL Cookbook , the review

When I read on the internetz that Alex Davies was about the publish a Packt book on MySQL HA I pinged my contacts at Packt and suggested that I’d review the book .

I’ve ran into Alex at some UKUUG conferences before and he’s got a solid background on MySQL Cluster and other HA alternatives so I was looking forward to reading the book.

Alex starts of with a couple of indepth chapters on MySQL Cluster, he does mention that it’s not a fit for all problems, but I’d hoped he did it a bit more prominently … an upfront chapter outlining the different approaches and when which approach is a match could have been better. The avid reader now might be 80 pages into MySQL cluster before he realizes it’s not going to be a match for his problem.

yum install mariadb

I`m not the biggest fan of openSUSE but this weeks post by Colin Charles makes me happy ..

openSUSE users can now do a mariadb install from their default repositories.

With all the fuzz about Snoracle and MySQL’s future last year to me it became clear that we would end up having different MySQL based distributions, probably with different names, and that it would be up to the Linux distributions to provide the users with what they preferred, working with those Linux distributions
therefore would be very important for the MySQL distributions.

Inuits Day

Couple of Fridays ago we had one of our @Inuits days again. Rather than having some people give talks and presentations about what they have been doing for the past couple of months this time we set out to research, test, and build stuff.

We split up in 3 different groups, one focusing on CI and testing freshly build stuff with cucumber, a second one setup and tested Galera

We setup a 3 node Galera cluster , not really as smooth as we’d like to ..

MySQL HA , an alternative approach

For those who’ve seen my presentation on MySQL HA, you already know that I often use a multimaster setup with a meta OCF resource that groups my favoured MySQL instance with the service ip , using a meta resource means that pacemaker monitors mysql, but it doesn’t actually manage it. It’s an approach that works for us.

One of the other approaches I will be looking at soon is the freshly released OCF resource that Florian announced last week.

Linux Open Administration Days 2010

So about 4 monts ago there was the crazy idea to start a new FOSS event in Belgium targeted at sysadmins.

What started out as an event for local people to meet local people with some local speakers actually ended up being a small local event with some top international speakers on onfiguration mananagement and system administration mixed with a bunch of good local ones !

I had the honour to open the conference with an extremely short version of the Devops talk I gave earlier last year.. extremely short as I knew that over the course of the weekend the topic would reoccur a lot.
