common_schema 1.1 released: split(), try-catch, killall(), profiling
+2 Vote Up -0Vote Down

I'm very happy to announce the release of common_schema, version 1.1 (revision 300).

This version boasts with compelling new features: innovative QueryScript syntax, libraries, views which add to your skills as a DBA, making some maintenance and management tasks a breeze.

  • QueryScript, split statement: automagically break long queries into smaller chunks, avoid long locks and reduce query/transaction overhead
  • QueryScript, try-catch statement: just try { something; } catch { act_on_error; }.
  • killall(): quickly kill connections based on grantee/user/host information.
  • profiling/profiling_last: utility views to assist in query

Free but not Gratis: A call for Open Source for everyone!
+0 Vote Up -0Vote Down
The term Open Source is not as old as you may think, and the concept actually predates the name. Initially the keyword was Free not Open, but Free is here in the sense of Freedom not in the sense "without cost", and this conflict in the English term "Free" was one of the big reasons that Free really wasn't a good word here. Which all in all doesn't mean that Free isn't still used to describe the Open Source movement, like in FSF (Free Software Foundation).

And Free as in Freedom, not Free as in "without cost", is an important distinction. What the deal was, in my interpretation at least but there are many different views here, was that the software should be available for use by anyone and for any purpose as long as they followed the rules. And the rules was there for a number of purposes, two important ones being:

Is Oracle really killing MySQL?
+16 Vote Up -1Vote Down
There are plenty of "Oracle-is-killing-MySQL" headlines in the tech world:

Is Oracle really consciously and willingly killing MySQL?

I don't think so.

Is Oracle damaging MySQL by taking the wrong steps? Probably so.

This is my personal opinion, and AFAIK there is no official statement from Oracle on this matter, but I think I can summarize the Oracle standpoint as follows:

  • There is a strong and reasonable concern about security.

Linus on Instantiation and Armadaification
+0 Vote Up -1Vote Down

I feel a sense of pride when I think that I was involved in the development and maintenance of what was probably the first piece of software accepted into Debian which then had and still has direct up-stream support from Microsoft. The world is a better place for having Microsoft in it. The first operating system I ever ran on an 08086-based CPU was MS-DOS 2.x. I remember how thrilled I was when we got to see how my friend’s 80286 system ran BBS software that would cause a modem to dial a local system and display the application as if it were running on a local machine. Totally sweet.

When we were living at 6162 NE Middle in the nine-eight 292, we got an 80386 which ran Doom. Yeah, the original one, not the fancy new one with the double barrel shotgun, but it would probably run that one, too.

The brief outage was due to a scheduled move of the servers to a separate rack and subnet dedicated to our work with the Center for Information Assurance & Cybersecurity (ciac) at the University of Washington Bothell (uwb), and a11y.com

I am currently exercising the new (to us) equipment and hope to winnow the less than awesome equipment over the next quarter. I spent the last six months finding the best in breed of the surplussed DL385 and DL380 chassis we (work) were going to have recycled. The team and I were able to find enough equipment to bring up one of each with eight and six gigs of memory, respectively. These will make excellent hypervisors for provisioning embedded instances of Slackware, Fedora, RHEL, CentOS, Debian, FreeBSD, OpenSolaris, OpenIndiana, FreeDOS, etc.

Proud and Excited To Be Part of the MySQL Open Source Community
+2 Vote Up -1Vote Down

Over the past few weeks since joining SkySQL as CEO, I have been meeting with team members to learn more about each person's views on the company, our customers and the industry. The team has done an amazing job since this company of original MySQLers re-emerged onto the scene more than a year and a half ago. We now have over 300 customers globally with very high satisfaction on the quality of services provided. July has for me been all about understanding the unique company culture and heritage from MySQL, and how we as a team can capitalize on our strengths to solve the challenges that our customers face while increasing the attractiveness of the MySQL ecosystem and community.

A Few Thoughts on OSCon and the Open Source Community
+1 Vote Up -0Vote Down

This past week I attended OSCon, the annual conference for open source’s true believers. And there was a religious fervor in the air, particularly from the point of view of someone more accustomed to Oracle conferences.

And if open source is the religion, proprietary closed-source companies are the devil. That having been said, I was surprised how virtually all large companies were demonized. Even long-time defenders of open source like IBM were ignored at best. That didn’t prevent them from coming though, with Microsoft and HP in particular with high-profile sponsorships and PR offensives that didn’t seem to have much influence with the crowd.

The companies generating buzz were the small companies built around development of their own open source products. There are a surprising number of them out

NIST::NVD 1.00.00
+0 Vote Up -0Vote Down

I’m leaving myself some room for bug fixes. It works for us in house. I would love to help others to give it a try. especially those who could benefit from making nearly immediately answered queries to the NIST’s NVD database.

The code in this release cannot by itself track the feed from the feds in real time. The nvd entry loader needs a little bit of love in the area of record merging before this starts working. It’s on my TODO list.

I’m sorry for the outage of git.colliertech.org. I’ll get that back up here shortly. In the meantime, feel free to grab it from this location while the CPAN indexes and processes my submission.

TunnelMaker, a simple script to generate multi-hop SSH tunnels
+0 Vote Up -0Vote Down

SSH tunnels provide a very effective means to access remote services and applications. Not only does it provide encryption of data between hosts, but it allows you to route connections between a sequence of servers, thus chaining connections. A common use of this method is to provide encrypted connections to MySQL servers so that user accounts can be limited to only “localhost” privileges, yet accessed from remote workstations without having to run MySQL+SSL.

The concept is simple, for example let’s say you have three servers: localhost (your workstation in America), a server in Europe, and a server in Japan. You want to access Apache running on port 80 on the Japan server but because of firewall restrictions you cannot access port 80 remotely, and to make things more difficult the Japan server only allows SSH connections from the Europe server’s IP. We can

MySQL Conference 2012 – The Keynotes (1)

Here it is finally: The MySQL conference 2012 starts with the Keynote Sessions.

The first keynote speech was by Peter Zaitsev, founder of Percona and a very smart guy, and by Baron Schwartz (Percona), another very smart guy, the brain behind a number of toolkits for MySQL. They’re talking about the MySQL Evolution – what I alluded to in my first post regarding this conference – the ways in which MySQL has grown, evolved, scaled and continues to make new inroads into new applications and industries.

From Peter: “What is most important hasn’t changed – MySQL is still a great piece of technology and it is evolving very rapidly.” (Love that quote!) Also “MySQL is also buzzword compatible: NoSQL, BigData.”

MySQL Conference 2012 Day 0
+0 Vote Up -0Vote Down

Wow! A lot has changed since the last MySQL conference I blogged about in 2007.

MySQL has been acquired twice: once as MySQL by Sun and the second time around bundled with Sun when Oracle bought Sun. The conference is no longer organized by O’Reilly but by Percona. And the MySQL database itself has changed — we were talking about new features in MySQL 5.1, which wasn’t released yet, along with Falcon (where did it go?). 5.1 has long since been released as has 5.5, and we’re now talking about 5.6 instead of 6.0. There was no “Cloud” on the horizon, nor was there MariaDB, XtraDB, Drizzle, Schooner, or any of the other offshoots of MySQL, all of which are creating a new buzz around the product.

Yet, one thing remains constant: the vibrant community around MySQL.

sphinx, sphinx_snippets() & MySQL 5.5
+0 Vote Up -0Vote Down

I've written a patch which completes Sphinx's integration with MySQL 5.5.

Up until a couple months ago, Sphinx would not compile with MySQL 5.5 at all. This is, thankfully, resolved as of Sphinx 2.0.3.

However, to my disdain, I've found out that it only partially work: the sphinx_snippets() user defined function is not included within the plugin library. After some quick poking I discovered that it was not added to the build, and when added, would not compile.

I rely on sphinx_snippets() quite a lot, and like it. Eventually I wrote the fix to the snippets_udf.cc which allows it to run in a MySQL 5.5 server.

Here are the changes for the 2.0.4 version of

Dear Kettle fans,

Today I’m really excited to be able to announce a few really important changes to the Pentaho Data Integration landscape. To me, the changes that are being announced today compare favorably to reaching Kettle version 1.0 some 9 years ago, or reaching version 2.0 with plugin support or even open sourcing Kettle itself…

First of all…

Pentaho is again open sourcing an important piece of software.  Today we’re bringing all big data related software to you as open source software.  This includes all currently available capabilities to access HDFS, MongoDB, Cassandra, HBase, the specific VFS drivers we created as well as the ability to execute work inside of Hadoop (MapReduce), Amazon EMR, Pig and so
