Learnings from Swift becoming opensource

Swift is now opensource, and it’s interesting to see Craig Federighi talk about it. This is Apple doing right, considering FaceTime is long overdue to being an open standard. People are nitpicking on Apple’s Open Source tagline, but really, this is akin to nitpicking on Mark Zuckerberg donating 99% of his Facebook stock to his new limited liability corporation charity (key: don’t look a gift horse in the mouth).

Apple has chosen to put …

Mark Callaghan at the Korean MySQL Power User Group

The Korean MySQL Power User Group gets a special guest speaker next weekend (Oct 31 2015 – 4pm – 4:33’s offices in Gangnam — nearest train stop is Samseong station, Line 2 — post requires Cafe Naver login) — Mark Callaghan (Small Datum, @markcallaghan, and formerly High Availability MySQL). I’ve been to many of their meetups, and I think this is a great opportunity for many DBAs to learn more about how Mark helps make MySQL and MongoDB better …

Learn to stop using shiny new things and love MySQL

A good portion of the startups I meet and advise want to use the newest, hottest technology to build something that’s cool, but not technologically groundbreaking. I have yet to meet a startup building a time machine, teleporter or quantum social network that would actually require some amazing new tech. They have awesome new ideas with down-to-earth technical requirements, so I kept wondering why they choose this shiny (and risky) new stuff when all they need is a good ol’ trustworthy database. I think it’s because many assume that building the latest and greatest needs the latest and greatest!

It turns out that’s only one of three bad reasons (traps) why people go for the shiny and new. Reason two is people mistakenly assume older stuff is slow, not feature rich or won’t scale. “MySQL is sluggish,” they say. “Java is slow,” I’ve heard. “Python won’t scale,” they claim. None of it’s true.

osquery is neat

Facebook recently made opensource, osquery. It gives you operating system data via SQL queries! Its very neat, and you can test this even on MacOSX (it works on that platform & Linux). It is by far the project with the most advanced functionality, linked here in this post.

I noticed that rather quickly, there was a PostgreSQL project, called pgosquery, based on Foreign Data Wrappers with a similar idea. (apparently it was written in less than 15 minutes; so a much lower learning curve than the regular MySQL storage engine interface)

I immediately thought about an older MySQL project, by Chip Turner (then at Google, now at Facebook), called …

GUUG Frühjahrsfachgespräch 2014: CfP ends on May 31st!

The German Unix User Group (GUUG) will hold their annual conference "Frühjahrsfachgespräch" on September 23-26 this year (I know, not really "Frühjahr" anymore, but this is how it is).

The Call for Presentations is still open until May 31st. Talks can be proposed in German and English, and there are slots for longer tutorials as well.

The range of possible topics is broad, so if you think you have anything interesting to share with a very passionate and technical audience of sysadmins and developers, here are some suggestions:

  • Operating Systems/Applications: architectures, privilege concepts, new developments, administration, mobile systems
  • Relevant new OS Kernel features: new developments in Linux-, BSD- or other Spen …

Korean MySQL Power User Group

If you are a MySQL power user in Korea, its well worth joining the Korean MySQL Power User Group. This is a group led by senior DBAs at many Korean companies. From what I gather, there is experience there using MySQL, MariaDB, Percona Server and Galera Cluster (many on various 5.5, some on 5.6, and quite a few testing 10.0). No one is using WebScaleSQL (yet?). The discussion group is rather active, and I’ve got a profile there (I get questions translated for me).

This is just a natural evolution of the DBA Dinners that were held once every quarter. Organised by OSS Korea, and sometimes funded by SkySQL, people would eat & drink, while …

Amazon EC2 Linux AMIs

If you use Amazon Elastic Compute Cloud (EC2), you are always given choices of AMIs (by default; there are plenty of other AMIs available for your base-os): Amazon Linux AMI, Red Hat Enterprise Linux, SUSE Enterprise Server and Ubuntu. In terms of cost, the Amazon Linux AMI is the cheapest, followed by SUSE then RHEL. 

I use EC2 a lot for testing, and recently had to pay a “RHEL tax” as I needed to run a RHEL environment. For most uses I’m sure you can be satisfied by the Amazon Linux AMI. The last numbers suggest Amazon Linux is #2 in terms of usage on EC2.

Anyway, recently Amazon Linux AMI came out with the 2014.03 release (see release notes). You can install MySQL …

Open Business Models

When I started writing this I wrote "Last week Opscode came" obviously now that is "A couple of months ago Opscode came with a bunch of announcements ... one of them being that they are also going to support the Open Source Chef .. rather than only their own platform.

I'd love to see more companies formally do this .. Over the past couple of years I've had numerous situations where organizations where happy to pay for support to an commercial backer of Open Source software... but they were not interested in , software updates, fancy dashboards , unneeded features.

Let alone being limited by some of the features of the Enterprise product (what do you mean there's no vlan support in Xen ? We've been using that for ages (anno 2008)

Even right now I`m talking with a customer that is interested in getting …

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.

Yet the next step is that we run into missing features, such as the fact that every contact you create by default is
set to private .. which really isn't productive for a CRM system where you want to be able to follow up on different
customer and share information.

So we tried figuring out what the database changes to do this in …
