Update: This was from the far past, and I'd thought it best to move this information to my blog. Currently, there's no development done with M0n0 as I no longer have any access to the Contivity equipment. Regular M0n0wall images will run, just without the serial console working. What you can do in this case is to use a network cable to access the webgui to assign LAN/WAN nics, and IP addresses. N0rwall image itself is no longer available.

Overview

N0rwall is a project inspired by the now famous M0n0wall project. The latter can be found at http://m0n0.ch/wall . The company I work for had purchased several Nortel Networks Contivity 100 systems to build our VPN to connect several offices in different states. More information can be found …

I am getting closer to finally holding a university degree in my hands. I am now all through with exams. Well admittedly I still need some signatures, but I trust the two professors in question to keep their word.

So now I just need to finish writing my thesis paper. But things are looking good there as well. I have the bulk of the literature search done and I have read most of the material. I will probably try to catch a few of you readers on planet OSDB for an interview, but more on that when the time is ripe.

In preparation of the post-degree times, I met up with one of those financial advisors that hunt down comp sci students at the uni campus. Its quite easy to see through their standard propositions, analogies and pretty diagrams. But they do know a few things here and there that are interesting. They also know some aspects of what the market is like (note sure if they …

I’m happy to announce new releases of MaxDB 7.6. The Devs have put a lot of time and energy into this release and it addresses many issues. Take a look through the Change Log for some details.

At MySQL we believe quite a lot in peer review - after all, we are open source! I read this comment about some cluster tutorial slides and thought it was quite funny

in the split brain and some other picture there is a grayed-out blotch in the middle which looks like a contraceptive device for copulating clams - what is it?

OK, back to killing bugs.

It’s no great secret that I think the stability of OpenOffice.org2 Impress in what’s shipped in Ubuntu Breezy leaves a lot to be desired. By ‘a lot’ I mean copy and pasting is unreliably and the Slide Sorter just stopped working for me without crashes (in at least one document).

However, I took the plunge and did something I usually don’t like doing - installing non-official debs.

deb http://people.ubuntu.com/~doko/ubuntu/ breezy-updates/
deb-src http://people.ubuntu.com/~doko/ubuntu/ breezy-updates/
I am now a much happy camper.

Saving is still amazingly slow, but the lack of crashes has made my week.

doko is my hero for the week. A Tip Of The Hat for him.

Hola,

I really got to get organized. There's just too much little things that seem to remain unfinished for...well, like forever. So, I'm pushing some of the nearly finished or at least usable stuff to the web. Maybe someone else might benefit, and maybe I'll get the kind of feedback that will take it to the next level.

Organization Charts

Since a couple of days, I've been developing a javascript library to render Organization Charts on web pages. Dude, it's even documented... The good news is that it renders decent on Mozilla/Firefox and Internet Explorer. The bad news is that Opera seems to have a little bug or quirk that messes up the connecting lines. (Details: see my post at …

Every so often people ask me the question how should they estimate memory consumption by MySQL Server in given configuration. What is the formula they could use.

The reasons to worry about memory usage are quite understandable. If you configure MySQL Server so it uses too small amount of memory it will likey perform suboptimally. If you however configure it so it consumes too much memory it may be crashing , failing to execute queries or make operation to swap seriously slowing down. On now legacy 32bit platforms you could also run out of address space so that had to be watched as well.
Having said so, I do not think looking for the secret fomula to compute your possible memory usage is the right approach to this problem. The reasons are - this formula is very complex nowadays and what is even more important "theoretically possible" maximum it provides have nothing to do with real memory consumptions. In fact typical server with 8GB of …

There have been some really cool postings at PlanetMySQL that I have been wanting to read and blog about. However, since I have been really busy (temporarily), I haven't had the chance to do so. Following is the list of posts I really liked, or would like to read at some later point.

• Podcast at Splunk.com: Brian Aker, Dana Gardner and Michael Baum talk about troubleshooting. (Thanks Markus)
  
• Zack pointed out that Sun is planning to Open Source Java
• MySQL Statement Log Analyzer (SLA) v 1.2 is now available.
• …

At the MySQL conference Timour Katchaounov presented one of my favorite sessions. I have my notes from the session speeding up queries posted on my blog.

Recently, Timour was kind enough to email me the links to his and some other talks at Google.

I have been really enjoying the "How I work" series by Dave Rosenberg as it provides very good insight into how our peers work.

Here are some of my favorites (no particular order):
Brian Aker
Sheeri Kritzer
Jason Gilmore
Mike Olson

I have been really busy working on a few projects for clients and haven't been getting any free time. Hopefully this weekend I can reply to everyone who has been kind enough to email me.
