If you’re using the new Arthemia theme for WordPress you might notice that there are two areas of the theme that can have articles promoted to; namely Headline and Featured sections. This is controlled by category association. Basically you have a post and if you want it in the Headline area of the theme you attach the category “headline” to it, similarly for the featured section. Now, let’s say you don’t want to manually change this all the time since it can be time consuming to promote posts to those categories if you want rotating content.

Here’s a simple solution. In this bash script I connect to MySQL and remove the current associations from posts and then randomly choose posts to be promoted to the Headline and Featured categories. This can be modified for other ideas you might have involving categories/posts/randomized …

So in my blog series I try to cover all additions to PHP trunk so I have to mention scalar type hints.

<?php
function print_float(float $f) {
    echo $f."\n";
}

for ($i = 1; $i < 5; $i++) {
    print_float( $i / 3 );
}
?>
        

0.33333333333333
0.66666666666667

Catchable fatal error: Argument 1 passed to print_float() must be of the type double, integer given, called in typehints.php on line 7 and defined in typehints.php on line 2

Is expected behavior in PHP's trunk. If you want such a thing to work please use the numeric type hint.

In case that wasn't enought fun: There's more!

<?php
function handle_result(int $i) {
    echo $i."\n";
}

$pdo = new PDO("mysql:host=localhost;dbname=test", "user", "pass"); …

A common observation for many LAMP stack products is the use of poor MySQL security practices. Even for more established products such as Wordpress don’t always assume that the provided documentation does what it best for you. As per my earlier posts where I detailed installation instructions and optimal permissions for both WordPress and Mediawiki, and not just directed readers to online documentation.

In this post I will detail why GRANT ALL is bad.

Let’s start with what GRANT ALL [PRIVILEGES] provides. As per the MySQL 5.1 Reference …

I am going to take a mulligan on a previous Blog Post on Open Source BI reporting tools. Part of my job at Calpont is getting familiar with tools folks with use with the InfiniDB storage engine. After all, what is the point of having all those terabytes in a data warehouse if you can not produce some sort of report from them. Three popular open source BI reporting tools are available from BIRT, Pentaho, and Jaspersoft.

Proceeding alphabetically, BIRT is part of the Eclipse IDE world. A BI report is a new project or new report under a project. And if you like Eclipse or Java IDEs, then you will probably like BIRT for reports.

Pentaho's …

After enjoying the excellent hospitality of our host here in Pisa (6 courses) we were ready for our second day at YAPCEU 2010 here in sunny Pisa.

Larry’s new catch phrase “My Language is a four letter word” was the ‘Buzz word’ for today. We settled down to some very interesting talks, the highlight for me being Tim Bunce’s talk on using Devel::NYTProf to Optimize your code. Tim first gave us a quick and dirty overview of optimization which covered the basics of where to start and what to look for he followed up with real examples of Optimizer output and than wrapped up with a few before and after results on an optimization effort.

The rest of the day was dedicated in my opinion, to the future of DBs in with Nelson Ferraz giving an excellent presentation of his concepts for using Perl as to glue for a Data Warehouse application. Next on my agenda, Martin Berends reports on the present state of Perl 6 and interfaces …

If you like to keep your ddl backed up in some source management tool like svn or cvs and want to do it individually for stored procedures, events, triggers, tables and such rather than having a single file you can easily do so using the below. You could even include the –skip-dump-date or –skip-comments and use the below to compare ddl daily checking for alterations thus making sure you are aware of any ddl changes done on the database.

user=backup_user
password=`cat ~/.backup_password`
hostname=127.0.0.1
port=3306
dbname=test_db
path=/home/mysql/ddl
date=`date +%Y%m%d`

mysqldump -u$user -p$password -h$hostname -P$port --no-create-info --no-data --no-create-db --skip-opt $dbname > "$path"/"$dbname"_triggers_"$date".sql
mysqldump -u$user -p$password -h$hostname -P$port --routines --skip-triggers --no-create-info --no-data --no-create-db --skip-opt $dbname > …

Firstly, if you have not yet seen the Session Schedule for OpenSQLCamp 2010 Germany, take a look -- great work Lenz! I am sad that I will be missing it on Aug 21-22nd.

However, this post is mostly about OpenSQLCamp Boston, which I am planning. I am working on a good hotel room rate -- hotel rooms in the Boston area are pricey, and I'm trying to work out something at $159 per night or lower. I will let you know if that happens, otherwise we will probably be on our own for hotel rooms.

Within a few hours my post Installing Mediawiki on Oracle Enterprise Linux LAMP stack got 5 negative votes.

Wow, I’d be glad if these people could felt so passionately about all the other CRUD on Planet MySQL that has ZERO to do actually do with MySQL.

Using a LAMP product, and providing instructions for operation can’t be a negative voting offense. So it can only be the words “Oracle Enterprise Linux”.

For those negative people out there that care enough to physically mark blogs let me share some facts with you. RedHat Enterprise Linux (RHEL) is the most widely used and support platform for production MySQL environments. CentOS and Oracle Enterprise Linux (OEL) provide via the freedom of Open Source, their own offerings of RHEL with various other features including …
