So what am I up to?
I am taking a vacation.
What does that mean?
I am on a "Hacker Holiday"
In other words I am at staying at home and screwing around with
some technology that I have been wanting to look at.
One of the things I am trying to do is see why my network goes
down the tubes every so often (or am I supposed to now say the
Tubes get full?). I use DD-WRT , http://www.dd-wrt.com/, on all of my routers.
I got the brilliant idea of enabling QOS on Wednesday to see if I
could get better bandwidth shaping. This pretty much broke
everything... I disabled it suspecting that it was causing the
router to max out its CPU only to discover that the network
issues were related to the maximum number of open connections
that my WRT54GL can handle. Which means that I need to find a
faster box to run DD-WRT on. Problem is... I …
A week ago, I noted the following:
The MySQL 5.0.26 released 3 Oct 2006 contains an embarrassing ABI breakage. We?re fixing this bug right now, and making a new build including the first binaries which will carry the name ?MySQL Community Server? and ?MySQL Enterprise Server? (which obviously did not exist on 3 Oct 2006). We?ll notify both our community and our customers of the new builds when they?re available.
Sorry about the trouble. We?re also improving our internal QA and build processes, in order to avoid future, similar problems.
Now, we have fixed the ABI breakage and built new releases.
- MySQL Community Server 5.0.27 is built and the packages are being seeded to our mirrors. We will send a release announcement, as we’ve always done, to …
A few weeks ago, I was holding a PHP training for a customer who's using the Oracle database on a regular basis. My boss and I agreed on teaching the Oracle database connection with PDO (instead of the MySQL database connection we usually teach in trainings).

[Read more]I am waiting and seeing how this new MySQL Enterprise Edition shapes up and how it affects the Community Edition, the Community, and MySQL users as a whole, but everything I have heard about it so far, from official press releases, initial public feedback, and information given to me, I am very impressed with it. This move shows every sign of being well-planned, designed to work positively for all parties concerned, from MySQL staff to paying customers to community members. What I see is added value for paying customers, better reasons for purchasing the paid edition, a focusing of MySQL's resources to better develop the product as well as to devote support to their customers, and importantly, an enabling of the community to be even greater participants than before. Some things taken for granted by some community members such as frequent binary updates may cause some disappointment, but I view this as a small price to pay, and an encouragement to …

As I mentioned in the previous post, shiflett.org is being redesigned and redeveloped from the ground up. (Nope, it's not finished yet; you'll know it when you see it.) One of the things I want to improve is commenting. This blog has been getting a lot of comments, and I really appreciate that. (Thanks!) Since the topics I talk about (PHP, MySQL, etc.) are technical, I want to let you add formatted code listings to your comments.
I've been playing with this tonight. Feel free to follow along as
I go. The first thing you want to do is create an ordered list
from the code you want to format ($code in these …
In a dramatic twist on Oracle's news yesterday that it will be offering support for Red Hat's Enterprise Linux, word on the street is that MySQL is considering offering support for Oracle's venerable database.
The hitch, however, is pricing. Early estimates suggest that MySQL would need to charge 1000% the cost of Oracle's typical pricing to make a profit on the support, given the persistent bugginess of proprietary databases compared to MySQL.
/tongue in cheek :-)

Maybe this is common knowledge by now, but I've seen this problem
popping up at work and I've run into it today. I upgraded Fedora
4 to 5 and wanted to get MySQL 5.1.11 on it instead of the MySQL
5.0 delivered with Fedora 5. This also goes mostly for Red Hat EL
btw..
These were the things I had to do, on a system without any
production databases. Do not do this on production without
backups and lots of coffee!

- Download the generic RPMs from http://dev.mysql.com/downloads/: Server, Client,
libraries and headers and the shared libraries. Put them all in
one directory.
- run in that directory: rpm -Uvh MySQL*
- If point 2 didn't give errors, you going to have problems
starting MySQL.
- mysql system user is missing. To recreate it:

Walmart.com is relaunching, and has open source at its core. MySQL? Well, probably (that's a given these days), but this news is even more significant, because it's OpenLaszlo from Laszlo Systems. OpenLaszlo is a great way to add rich media functionality to your website. WalMart agrees.
The real question, given WalMart's reputation for driving down vendor pricing, is how much lower than free did it require? :-)

SHOW STATUS and SHOW VARIABLES are very useful features for analyzing server performance, server setup and general debugging. Many times, there are items applicable to a scenario in both lists. Further, sometimes it’s difficult to know whether an option or variable can be changed on the commandline or in an option file.
For example, let’s say you are debugging a lot of aborted connects. You may care about the following items in “SHOW …
