I think nobody would argue today, that search engines are most import sites in todays Internet. There are lots of information sources in the Net today, and every day they are generating lots of useful content. One of major parts of this content is generated by forums aka bulletin boards. But Google - most popular search engine is not to efficient on this side of search - if you try to find something using Google, you can find information on some public forum, but Google SERP is designed for generic pages search and search results will be not so clear. That is why more specialized search engines are so popular. Technorati, Google and Yahoo blog search engines, etc are really popular today.

Just few days ago new search engine was released. Its name is Board Reader. IMHO, its major advantage of this search engine is specialization on search by …

Is it possible to run Stored Procedures on MySQL 4.x? Yes and no - of course the feature is not available directly in MySQL 4.x, but if you have a MySQL 5.x server with the FEDERATED Storage Engine available, it's no big deal to accomplish that.

Here's how it works - we start with this on a MySQL 4.x server:

mysql> SELECT version();
+-----------+
| version() |
+-----------+
| 4.0.18-nt |
+-----------+
1 row in set (0.03 sec)

mysql> SHOW CREATE TABLE tt \G
*************************** 1. row ***************************
       Table: tt
Create Table: CREATE TABLE `tt` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `val` int(10) unsigned NOT NULL default '0',
  `ts` timestamp(14) NOT NULL,
  PRIMARY KEY  (`id`)
) TYPE=MyISAM
1 row in set (0.03 sec)

mysql> SELECT * FROM tt;
Empty set (0.03 sec)

The next step …

Kynan and I came along to the MySQL camp, and thru a quirk of fate pretty much ended up running it (the person who was meant to be running it got injured on the first day and had to go off to hospital). In return we wrote the Google Code blog post about the event. Pretty cool, huh?

Goal of a MySQL system administrator is to have regular, consistent backups of the
databases with minimal impact on the database application. The backup process should
also limit the use of CPU, memory, network resources so that application is not impacted.
Optimal backup method must be choosen to keep the backup window as small as possible.
The backup parameters depends on various factors - number and size of databases, number
of MySQL servers, MySQL configuration, data security.

ZRM for MySQL provides consolidated backup and recovery for MySQL databases. ZRM
for MySQL provides extensive list of options to tune the backup process for the user
environment. It also tracks lots of backup parameters that are available to the administrator
to tune the backup process.

Mark Webbink, Red Hat's deputy general counsel and secretary, looks at the Microsoft/Novell agreement through a historic lens...

As a history buff, reading the Novell and Microsoft open letters this morning conjured up the image of British Prime Minister Neville Chamberlain standing in front of 10 Downing Street in 1938 and declaring: "My good friends this is the second time in our history that there has come back from Germany to Downing Street peace with honor. I believe it is peace in our time."

We all know how well that turned out.

...and discovers that all that glitters is not gold:Microsoft's principal objective in this exercise was to get someone ostensibly from the free and open source software community to acknowledge the tacit validity of Microsoft's patent portfolio. And despite Hovsepian's protestations to the contrary, …

The FEDERATED storage engine is a MySQL feature that lets you access the tables (and views) on a remote MySQL server. In terms of purpose and functionality, it best compares to a "linked table" in MS Access, and to a lesser extent, to Oracle database links.

Creating a federated table is tedious, because in the local database, you need to define a table with exactly the same structure as the remote table. That includes the index definitions, because these are used by the local optimizer to create a query plan (although the statistics for the index will not be locally available)

I created a procedure to make life easier (well, at least as far as creating FEDERATED/ tables is concerned). You can grab if here:

There is a poll up on strict mode:
http://dev.mysql.com/tech-resources/quickpolls/strict-mode.html

You need to go to this URL to post:
http://dev.mysql.com/tech-resources/quickpolls/strict-mode.html

So what is up with the poll? It comes from a conversation where myself and Monty were wondering how many people are using it/know about it. I asked the marketing people (thanks Edwin!) to post it. Strict mode is the mode inside of MySQL that keeps "bad data" from being inserted into tables. It was added inn 5.0.

It should be obvious that someone from Marketing didn't write it just because of the language (look at previous topics, and then ask yourself about which of them look more Slashdottish).

"So is this call about an S3 or a Big Table knockoff?"

That was my question to the recruiter.

Let us wind back history for a moment.

This sparked a lunch conversation about these sorts of technologies. Big Table to me is an implementation of the problem that all large systems eventually hit. I refer to it as the "image server" problem, because the image servers for most companies are where it normally first manifests itself. If you read Brad's notes over the years on LJ you can see one of the more publicly available evolutions of a system to solve this problem.

My interest in the problem is that I've …

Since the recent demise of my Thinkpad, and the musical hard drive game leading the Thinkpad's hard drive being installed in the Toshiba, the Toshiba has been operating with an insufficiently sized swap partition. This has led to severe performance problems, particularly when doing MySQL builds. So I enlarged the swap partition, deleting the operating system partition and in fact replacing it with two equally sized partitions, similar to the partition layout on the Toshiba's original hard drive.

So of course this required me to reinstall Slackware, MySQL, and PHP. I have found the Apache bundled with Slackware 10.2 to be ample for my needs so far. So first I ran my pulls script to pull and build all the different MySQL source trees, and installed the six instances I normally operate. So far so good. Then I turned my attention to installing PHP.

The first time I installed PHP (5.1.4) I must have had an extraordinary …
