New version of libAttachSQL, C connector for MySQL released!
+0 Vote Up -0Vote Down
It has been just over 2 weeks since the last libAttachSQL version was released.  I had a great vacation in the middle which for once meant that I didn't do any work for the week I was away :)

For those who don't know about it, libAttachSQL is a lightweight, non-blocking C connector for MySQL servers.  It is Apache 2.0 licensed so plays well with both Open Source and Commercially licensed applications.  I have been developing it for 2 months now as part of my work for HP's Advanced Technology Group.  It is hosted on GitHub and uses many freely available tools (such as Travis CI) to host and test various parts of the project.

libAttachSQL 0.2.0 alpha released!
+0 Vote Up -0Vote Down
Hot on the heals of last week's release we have released version 0.2.0 alpha of libAttachSQL.  For those who have missed my previous blog posts, libAttachSQL is a lightweight C connector for MySQL servers I'm creating with HP's Advanced Technology Group.  It has an Apache 2 license so is good for linking with most Open Source licenses as well as commercial software projects.

Changes in this release:

  • Added support for query result buffering
  • Passive connect on first query is now asynchronous
  • Improved memory handling
  • Many documentation changes, including API examples
  • Many other smaller fixes
For more information see the libAttachSQL

libAttachSQL 0.1.0 alpha released!
+0 Vote Up -0Vote Down
As I briefly mentioned in my previous post, I have been working on a new project for HP's Advanced Technology Group called libAttachSQL.

libAttachSQL is a lightweight C connector for MySQL servers.  It is Apache 2 licensed (and therefore compatible with many open source licenses as well as commercial use) and has a new asynchronous API.  With the new API you send a command which returns immediately and you poll until the library tells you there are results ready, this is very useful for applications that have many things going on that you do not want held up by waiting for the MySQL server to process a query.  In later posts I will give usage examples of this.

I am a great believer in

How cloud hosted services are helping open source
+0 Vote Up -0Vote Down
One big project I'm working on for HP's Advanced Technology Group right now is an Apache 2.0 licensed C connector for MySQL servers called libAttachSQL.  The whole process, not just the code itself, is helping us learn about new and current techniques in Open Source development.  Whilst I will be writing many posts about libAttachSQL in the future, today's post is about the free hosted services we are using around it.

GitHub

Almost all previous Open Source projects I have worked on in the past have been hosted on Canonical's Launchpad platform.  Over the last couple of years there has been a shift to using GitHub and almost everything I have worked on at HP has been hosted there.  Now

CoreOS Review
+0 Vote Up -0Vote Down
I have spent a few days now playing with CoreOS and helping other members of HP's Advanced Technology Group get it running on their setups.
Today I thought I would write about the good and the bad about CoreOS so far.  Many components are in an alpha or beta state so things may change over the coming months.  Also as a disclaimer, views in this post are my own and not necessarily those of HP.

Installation


As stated in my blog post yesterday, I have been using CoreOS on my Macbook Pro using Vagrant and VirtualBox.  This made it extremely easy to setup the CoreOS cluster on my Mac.  I made a minor mistake to start with, and that is to not configure the unique URL required for Etcd correctly.  A mistake a colleague of mine also made on his first try so it

Is Drizzle dead?
+0 Vote Up -0Vote Down
Yesterday someone opened a Launchpad question asking "is Drizzle dead?".  I have answered that question on Launchpad but wanted to blog about it to give a bit of background context.

As I am sure most of the people who read this know, Drizzle is an Open Source database which was originally forked from the alpha version of MySQL 6.0.  At the time it was an extremely radical approach to Open Source development, many features were stripped out and re-written as plugins to turn it into a micro-kernel style architecture.  Every merge request was automatically throughly tested on several platforms for regressions, memory leaks and even positive/negative performance changes.

In fact Drizzle has influenced many Open Source projects

Caveats with Eventlet
+0 Vote Up -0Vote Down
The Stackforge Libra project as with most Openstack based projects is written in Python.  As anyone who has used Python before probably knows, Python has something called a GIL (Global Interpreter Lock).  The GIL basically causes Python to only execute one thread at a time, context switching between the threads.  This means you can't really use threads for performance reasons in Python.

One solution to get a little more performance is to use Eventlet.  Eventlet is a library which uses what is called "Green Threads" and hacks on top of the networking libraries to give a mutli-threaded like feel to an application.  As part of this blogging series for HP's Advanced Technology Group I'll write about some of the things I found out

The importance of backup verification
+1 Vote Up -0Vote Down
I have recently moved to HP's Advanced Technology Group which is a new group in HP and as part of that I will be blogging a lot more about the Open Source things I and others in HP work on day to day.  I thought I would kick this off by talking about work that a colleague of mine, Patrick Crews, worked on several months ago.

For those who don't know Patrick, he is a great Devops Engineer and QA.  He will find new automated ways of breaking things that will torture applications (and the Engineers who write them). I don't know if I am proud or ashamed to say he has found many bugs in code that I have written by doing the software equivalent of beating it with a sledgehammer.

Every Devops Engineer worth his salt knows that backups are important, but one thing that is regularly forgotten about is

First version of Drizzle Tools for MySQL servers released
+1 Vote Up -0Vote Down
Today marks the first release of Drizzle Tools for MySQL servers.  Drizzle Tools aims to be a collection of useful utilities to use with MySQL servers based around the work on the Libdrizzle Redux project.

In this first version there is one utility in the tree called 'drizzle-binlogs'.  If you've seen me talk about this tool before it is because it used to be included in the Libdrizzle 5.1 source but has now been moved here to be developed independently.  For those who haven't 'drizzle-binlogs' is a tool which connects to a MySQL server as a slave, retrieves the binary log files and stores them locally.  This could be used as part of a backup solution or a rapid way to help create a new MySQL master server.

Due to the API changes before the Libdrizzle API became stable

My journey so far
+1 Vote Up -0Vote Down

July marks my sixth month working on the OpenStack project for HP. Over the past few years I have had people ask me about my journey to where I am now, especially students working on the Drizzle project. So I decided to write it today.

Back in 2007 I worked as a freelancer developing PHP code, doing DBA work and administering Linux systems. One of my biggest clients was an online magazine called The First Post, I was doing so much work for them they hired me as a full time employee under the title Technical Architect. We made great strides whilst working there and I even got the site running from a MySQL Cluster installation.

Towards the end of 2007 the magazine was in financial difficulty and there was a real risk of everyone losing their jobs over Christmas. As luck would have it one of our biggest fans was a guy called Felix Dennis who owns a magazine empire called Dennis

WebOS and the open alternative live another day
+0 Vote Up -0Vote Down

There has been no shortage of reaction to HP’s move to make the Linux-based WebOS open source software. Below, I offer some of my thoughts on the meaning for the different players affected.

*What’s it mean for WebOS?
Moving WebOS to open source was best option for HP. It retains some value in the software depending on its involvement. It is also the best fate for the code, rather then being sold or simmered to its IP and patent value or even used as another weapon in the ongoing mobile software patent wars. Still, the move comes amid huge developer and consumer uncertainty for WebOS. Nevertheless, at least WebOS was already in the market with a compelling products, the Palm the Pre, in the modern smartphone market. WebOS will hopefully have a faster path to open source than Symbian since the former is based on Linux. I still think the greatest opportunity for

The open card in the mobile game

I wrote last year about the way Google’s Android mobile operating system was serving as a more open alternative to Apple’s iOS, but not so open that it didn’t leave opportunity for an even more open alternative.

Given that we continue to see software patent-based attacks on Android, as well as swirling FUD around coverage of the attacks and never ending suits and settlements and courtroom developments, it is clear it will be a long time before any of this legal business is ever close to settled, unless ended by settlements first, which is likely.

However, I’m more interested in the technology in the meantime. I also think it’s

Is Android FUD a forebearer of Linux-like success?
+2 Vote Up -2Vote Down

Time is flying by so fast, it sure doesn’t seem like it was last year I was blogging about how Android is for real. Well, let me reiterate … Android is for real. The reason I say that and stress that is despite its success, we see a variety of legal threats, accusations and actual lawsuits to come flying at Android as fast as it is growing in the market.

Still, we seem to be able to fairly easily find agreement among vendors, developers and users that Android development is not slowing down, that legal maneuvering will not pave a path to success or that any ruling or action will take Android-based phones out of consumers’ hands. This is not to say that Android faces significant challenges: real fragmentation and version overload; a software development pace that may be too fast

HP Needs a Linux OLTP Database...FAST
+1 Vote Up -1Vote Down
Oracle, after dating HP, Dell, Netapp and EMC has found its mate in Sun. Oracle is now becoming a systems company, and unceremoniously dumping these former paramours. These leaves the spurned lovers to find alternate accommodations, especially in the area of the database.

As I have stated previously on this blog, the clear partner of choice on the Windows front is Microsoft. This is demonstrated by today’s partner announcement around MS SQL Server for OLTP. But who is their partner in the Linux segment?

The following are contenders:
* Postgres (HP rolls their own)
* EnterpriseDB (pre-rolled Postgres)

Data Warehouse/Analytic Appliances – What to Consider

Why was Teradata able to become the leader of data warehousing at the super high-end (e.g. greater than 25 TB’s)?  Why was Netezza only the second pure-play data warehousing company to go public by focusing on the 10 – 25 TB range of opportunities?  Why did Oracle after so many years of denial finally announce a joint hardware / software product for data warehousing with HP, the Exadata data warehouse server?  Why did Microsoft acquire DATAllegro, one of the earlier data warehousing appliances? Why are there now dozens of data warehouse appliances available on the market today, and – more importantly – how should a customer choose which one to purchase? 

In all these cases, the vendors have listened to the market and concluded that the most optimal way to serve the customer is through a true data warehouse appliance.  Given that there are so many flavors of appliances, though,

Proprietary, open source systems management get closer

CA and IBM, two of the so-called Big Four in systems management software, announced this week a federated configuration management database (CMDB) system for interoperability of their software. Something like this comoing from two of Big Four (BMC, CA, HP and IBM) wouldn’t normally hold much meaning for open source players such as GroundWork, Hyperic and Zenoss, but it actually does for a couple of reasons.

First, part of the technology that CA and IBM are using to link up their systems management software, which allows it to share information between the two CMDBs, is actually open source software itself from the Eclipse Cosmos Project. CA and IBM said the Eclipse Cosmos software accelerated implementation of the CMDB Federation (CMDBf) specification and the two
