One of my current interests is looking for bottlenecks in MySQL with
regards to the use of Multiple CPU usage.

I noticed Tim's comments yesterday on this topic:
http://radar.oreilly.com/archives/2007/02/a_fast_waitfree_1.html

What I see right now is that for the first time in years commodity
scaling with multiple CPU's is becoming a reality. What does this mean?

For years we have been scaling out, adding more hosts. Every hosts
increases the total cost of ownership. You can do this with two
processor hosts, but this is not all that interesting. Scaling for
two processors is quite easy, its when you get more then two that the
problem becomes interesting (Slashdot has had four processor machines
for its databases since 2001, but they were 32bit so the …

It's no secret to anyone that Microsoft caters to developers while Apple is faithful to end-users.  I happen to like Apple's approach since, as a developer, I actually do qualify as a user.  Microsoft should really be concerned since I don't think I would find too many people that would disagree when I say that if the market shares were even, Apple would seriously be in the driver seat.  I use Windows because that's where my money is made and where most of the applications I use exist.  Here is just one example where Microsoft unnecessarily makes things complicated.  Consider this screenshot of my installed apps (I'm using Vista x64).

Now, why do I have separate items listed for SQL Server VSS write, and setup support files, and native …

When you ask someone how to optimize SQL queries you will always get the answer

• enable the slow query log
• set the long-query-time to 1-2 seconds
• enable the logging of query which aren't using an index
• run EXPLAIN on the queries that are shown and optimize them with proper indexes

But how to understand what the EXPLAIN is telling you ?

I picked a query from the ORDER BY RAND article as they became interesting enough to show the different aspects of of a query. They contain:

• Sub-Queries
• Unions
• Special cases
• JOINs
• ORDER BY + LIMIT

If you want to understand how this query was developed, check the original article …

** This is an editied “re-post” of an item i wrote about a year ago. **

MySQL V5.0 has been out for a while; the current production community version is 5.0.27.

With version 5, MySQL has addressed most of the major objections people have that MySQL is not a “real” database. With support for triggers, stored procedures, views and XA transactions, I think MySQL has a feature set that will enable people to easily migrate to MySQL. At this point in time, InnoDB is the only storage engine choice for applications that require transactions, and this is still a reasonable choice in most cases.

The only open question for MySQL A.B. is resolution of the problems created by Oracle’s acquisition of Innobase Oy, the developers of the InnoDB storage engine. I previously wrote a post about the Oracle Innobase issues, the summary is that Oracle’s acquisition of Innobase Oy is a problem not because of the storage engine, but …

ZCS 4.5 helps make admins' jobs easier -- a lot easier in some cases. This post discusses advanced search in the admin console, backup and restore in the admin console, backup performance improvements, and good policies for creating a recoverable system.

Advanced Search for Users, Domains, Servers
We've added an advanced search capability to the admin console. It includes a search builder similar to what has been available in the end user client. We had heard from many customers that they wanted to create complex searches, such as "show me all domains with xyz in them" or "show me all users on server 3" or "show me all users with last name xyz on server 5". You can construct all these searches and quite a few more now, and since the search uses LDAP indexes it's fast. This feature is AJAX helping admins.

Backup and Restore in the Admin Console
For the ZCS 4.5 Network Edition …

So, OSDC 2007 (Open Source Developers Conference), held in Melbourne in previous years, will visit glorious sunny Brisbane this year (end November, early December).

My thanks to Anthony Towns, Andrae Muys and James Iseppi for helping me with the legwork and homework to put together our submission, and to the OSDC committee for giving us this opportunity - it'll be good.
More news (including the exact dates and venue) soon, Andrae is already preparing the Call for Papers.

If you are interested in helping and haven't written to me before, now is a good time.
Likewise, if you would like to sponsor this event, getting in early could get you an honourable mention even as early as the call for papers... that would get you nearly 10 months worth of exposure and good karma!
We actually received quite a few expressions of interest for sponsoring already; we'll be attaching sponsorships to specific …
