Well I have to say, Skype is a piece of crap. Between the abysmal sound quality/compression artifacting and the compatibility issues with my Gentoo install we had a nightmare trying to communicate, eventually resorting to text chat.

I think we clarified a few ideas during this session, mostly spec-related but with one or two interesting ideas cropping up.

One notable thought was local auditing; how do we watch local administrators' queries? We can't capture packets from their session since they're working on the server itself so what can we do? This may involve a whole other branch of code that allows us to send local server events to the auditing server for storage and flagging. I'm not entirely sure how we're supposed to sit between the user and the mysql server, especially if the user is a domain/local administrator and has some determination not to get caught!

Another interesting thought was rules; …

Welcome to the MySQL UDF Repository! The MySQL UDF repository aims to offer an organized collection of open source MySQL user defined functions.

There are numerous MySQL UDFs available in the public domain. However, most UDFs appear standalone. Often, binaries are not included: only the source code is available. In many cases, it is not straightforward to compile binaries for different platforms. Likewise, documentation and installation instructions are either scarce or missing. Also, there is little consistency with regard to naming conventions, error handling and error reporting.

The MySQL UDF Repository tries to improve that situation.
GoalsHere's a list of things the MySQL UDF Repository aims to offer:

Inserting user-defined DTrace probes into MySQL source code is very useful to help user identify the performance problems in the application level and the database server, In addition, the cost of the USDT probe is basically neglectable. Each probes inserted into the src can be enabled by adding the code like:

 If (PROVIDER_PROBE_ENABLED()

{

                PROVIDER_PROBE(arg0,…);

}

The steps to add DTrace probes into MySQL is very straightforward.

Step 1: Figure out what probes are needed to insert into the source code

This is the difficult part that requires you understand the MySQL implementation details. Generally, it is good to insert probes to clarify the DB response time distribution …

My colleague in a company offsite mentioned Vidoop which lets you have password that cannot be stolen via key loggers and someone looking over your head. Apparently, you select your password as photo categories (e.g. animal,person, boat). Then when you login you are shown random photos and with random letters associated with them. Your task is to type in the letter that's shown on photos within your chosen photo categories. So on one login, your password may be "ABP", and second time you may have to type "BAG." What makes me not put trust in them is their revenue sharing programs with the websites that implement this technology.

BTW, does anyone know if they use MySQL?

Thanks to MySQL community members we’ve got really great collection of media files from the recent mysqluc. Thanks to Seeri for all that work he’s done to collect everything in one place so we could watch/listen/read information from this great event.

So, if you did not attended mysqluc07, then you definitely should visit Technocation page, dedicated to this conference.

P.S. I’m going to post links to these videos and descriptions for the sessions on the Best Tech Videos soon, so If you are not sure to watch some video or not, just wait while I’m merging these links with information from mysqluc site.

Immediately after my presentation about my MySQL S3 storage engine, I was interviewed by Eric Lai, a reporter from ComputerWorld. The resulting article is here, and was abstracted by the conference here.

Also, Sheeri Kritzer recorded me. Here is the audio and the video.

When I get the larger form of the video, I'll push it into an S3 bucket/item and make it world readable...

When MySQL first came out and started popping up all over the web in the e-commerce arena, if you were like me you looked at it as a wannabe. 'Call me in a few years when you grow up'. Yea, sometimes the Oracle in us goes to our heads a little to fast...MySQL has really gone mainstream in the last few years. Companies that never would have considered MySQL in the past for critical database

Welcome to the 46th edition of Log Buffer, the weekly review of database blogs. PGCon 2007 has been happening just a few blocks from where I sit, and judging by what the bloggers have to say, organizer Dan Langille has done a great job putting together a very full conference. Let’s start with some blogs [...]
