Cross-breeding Template::Declare with Moose

Say hello to Template::Caribou. The goal of that new template system? Steal or be inspired by a maximal amount of Template::Declare features, while using Moose as the core engine. For the rest of this blog entry, I’ll take you on a tour of that basic sample use, peeling the system from the outside in, hoping that the glitter of the outer layers will soften the shocks of the abominations of the inner mechanisms.

Once again about innodb-concurrency-tickets

I had to refresh my knowledge on how InnoDB threads queue works the other day when debugging activity spikes on one of the customer’s production system and while I had general idea about InnoDB kernel and queue, thread concurrency and queue join delays I didn’t have a complete model of how InnoDB concurrency control works. So I started from manual…

Extreme Makeover: Dungeon Edition

I have been working on my game recently and wanted to check out how to dig some caves. Without readily available software to do my excavations, I decided to give it a shot myself. To come up with an algorithm to create a decent dungeon or cave system was the hard part. At the end, I went with a very simple recipe that seems to gives fair results.

UKOUG 2011 Conference OakTable Sunday by Alex Gorbachev

This year, there were ten Pythian folks attending UKOUG Conference and we did twelve sessions including multiple presentations, masterclass, RAC Attack workshop, round-table and 10 minutes OakTalk. I think it’s the record number of session Pythian folks did at a single UKOUG conference and the record number of Pythian peeps attending.

This is ultimately a good news!

Deploying Stuff With Git

Somebody at $work asked me how I use Git to deploy stuff, probably working under the false hypothesis that wisdom is in any way, shape or form affiliated with yours truly. The fool…Yet, it is true that I had my share of tinkering with Git, and that I might have gleaned from my experience. So I sent him a couple of links leading to more wisdom-certified sources. They are listed at the end of this blog entry; if you have more good articles/blog posts that you’d like to add to the pile, please don’t be shy and mention them in the comments. But I can’t just stop there, really. So, if you allow me, I’ll dust off the good ol’ soap-box, hop on it, and share my thoughts on the subject.

Is GoldenGate the Golden Gate

I have experienced a handful of Oracle’s replication solutions as far back as version 5 of the database in the mid to late 1980′s. Will GoldenGate be the golden gate? If one ends up answering in the affirmative to most of the following questions, I think so.

Using NOLOCK Hint

Use NOLOCK hint to avoid block – this is what I have often heard/see in many forums I participate in, during local user group events and meetings. I have always advised that its not that good idea to use hints, as it may cause data corruption and blocking. And anyways, there are many things that you can do to avoid blocking, like:
