LaraconEU 2016 - Overview
+1 Vote Up -0Vote Down

Last time I went to LaraconEU as in 2014 as speaker in the community track, it was my first international event ever speaking in english and I had jitters from it.

A lot a friends were made and it was nice to see all of them again this year.

What I also like about LaraconEU it is a Laravel conference that doesn’t talk always about Laravel, being a bit less insular than one would imagine.

Shawn McCool and his team made a great job this year and I was very honoured this year to be in the Track #1 (Blue Track).

The first round of applauses when I was introducing myself and saying …

PostgreSQL Day at Percona Live Amsterdam 2016

Introducing PostgreSQL Day at Percona Live Europe, Amsterdam 2016.

As modern open source database deployments change, often including more than just a single open source database, Percona Live has also changed. We changed our model from being a purely MySQL-focused conference (with variants) to include a significant amount of MongoDB content. We’ve also expanded our overview of the open source database landscape and included introductory talks on many other …

Data Streaming with MariaDB MaxScale
+0 Vote Up -0Vote Down

Thu, 2016-08-25 08:31Massimiliano PintoData Streaming with MariaDB MaxScale

While traditional analytics databases exists, Apache Hadoop is becoming the de facto data storage for big data. It’ an open-source software framework for distributed storage and distributed processing of very large data sets. There is a need for the ability to transfer data from MariaDB/MySQL operational data store into Hadoop. While tools such as Apache sqoop exist to export data out of MariaDB/MySQL into Hadoop - its performance is not suitable for streaming or real-time data transfer as it operates as a batch application.

To address this need, the MariaDB …

Shinguz: Beware of large MySQL max_sort_length parameter
+0 Vote Up -0Vote Down

Today we had a very interesting phenomena at a customer. He complained that MySQL always get some errors of the following type:

[ERROR] mysqld: Sort aborted: Error writing file '/tmp/MYGbBrpA' (Errcode: 28 - No space left on device)


After a first investigation we found that df -h /tmp shows from time to time a full disk but we could not see any file with ls -la /tmp/MY*.

After some more investigation we found even the query from the Slow Query Log which was producing the same problem. It looked similar to this query:

SELECT * FROM test ORDER BY field5, field4, field3, field2, …

Thoughts on MaxScale new license
+3 Vote Up -0Vote Down

MaxScale has been open source until now, just like all MariaDB projects. But the 2.0 version is released under a new license called BSL, which basically makes the covered work non-free until the Change Date (in this case 2019-01-01), when the license will be converted to GPL.

Looks like open source friendly, after all. The license will be GPL, just be patient. And the code is available. Right?

No. Cmpletely wrong. For plenty of reasons.

Some reasons

It is a lock-in. No matter how many times …

Fired for supporting open source
+2 Vote Up -0Vote Down

I have been fired for speaking out about the GPL and MariaDB actions that have caused great harm to our ecosystem.

It has been pointed out that I have a non-compete agreement. None of my tools compete with MariaDB and I have no non-public knowledge of MariaDB technology. GPLScale remains free software under the GNU GPL license and it is my right to fork a github repo. I am not paid to work on GPLScale and I don't intend to get paid to maintain it by anyone. All my projects are labors of love.


Who wants to hire me? I'm dedicated, honest, open, and I have integrity. I'm willing to risk everything for what I believe in.

Email me …

A look at Unicode with bash on Windows
+0 Vote Up -0Vote Down

When I wrote this blog about “bash on Windows” a few days ago I omitted one issue, that I already knew about. This is because it needs some elaboration that did not ‘fit in’ the previous blog. So I will do it here.

It is about Unicode. Unicode always was a pain in “cmd” and with the arrival of “bash” in Windows, this has become more significant and important. Actually on any recent *nix platform user will not do anything to make Unicode work ‘out …
