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 …[Read more]
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.
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 …[Read more]
MySQL team attends and speaks at the MOSC 2014 on September 24-25, 2014 in Kuala Lumpur, Malaysia. We are having a MySQL booth and above that our local colleague Ricky Setyawan has secured one 45 minutes talk scheduled for Wed, Sep 24 @2:15-3:00pm on the MySQL Web Reference Architecture.
We will also run two hours workshop on MySQL Fabric scheduled for Thursday, Sep 25 @2:30-4:30pm. If you are around do not forget to come to our booth and/or visit our MySQL session & workshop!
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 …
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).[Read more]
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 …[Read more]
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 …[Read more]
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.
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 …[Read more]
Towards the end of last year, I was asked to investigate the Red Hat Software Collections by someone that popped by one of my talks. SkySQL has been working heavily with Red Hat, and with Fedora 19 shipping MariaDB as a default, it seems like MariaDB is getting even more distribution. The Red Hat Software Collections 1.0 Beta is now available for users of Red Hat Enterprise Linux 6.
From a database standpoint, users now get MariaDB 5.5. I encourage all to try it, as it is an in-situ upgrade. It is described as:
MariaDB version 5.5, which introduces an easy-to-adopt alternative for MySQL for Red Hat Enterprise …[Read more]
