MySQL 5.1 continues community release madness - Kevin Burton

Kevin Burton — Wed, 03 Dec 2008 05:44:13 +0200

Yes. A REALLY good way to get MySQL to stop doing this is to stop buying their Enterprise product.

I don't understand the logic really.

Why would I want to use a product that has *less* QA?

MySQL 5.1 continues community release madness - z

before talking about stable ABI and API for storage engine plugins, they should think a bit about decoupling a shared library from the mysqld executable. That shared library cannot be used without loading mysqld seems nonsense.

New reward models for Habbo - Osma

Heh, re-reading that sentence I can see what you mean :)

New reward models for Habbo - Gerben

Haha, this made me laugh:

"the community feedback is overwhelmingly positive, despite its normal bias towards resisting change."

However these 'Pixels' look really promising and I'm really looking forward to how you guys will further enhance these features..

Helsinki Airport shows a clue about wireless networks - Osma

Osma — Wed, 26 Nov 2008 17:00:03 +0200

Dunno, haven't been there yet so I'm relying on a news report at this stage. WPA is broken though, so using it doesn't improve things by a whole lot, might be different with WPA2. That said, anything that needs security hopefully already is end-to-end secured with SSL rather than just to the nearest AP+switch..

Helsinki Airport shows a clue about wireless networks - Adam

Adam — Wed, 26 Nov 2008 12:04:28 +0200

But it still uses WPA, right? With the password publically prominetnly displayed all around the airport, right?

Or is it that they still only have *half* a clue?

Oh, and the 'lag' people are complaining about? Looks like Shockwave Player just can't keep up with all the stuff we throw at it these days. It takes a pretty fast machine to keep everything completely responsive today. We're working on the optimizations, of course.

Falcon database engine in MySQL 6.0 alpha - Osma

Osma — Sun, 04 May 2008 22:52:24 +0300

Kevin, thanks for taking the time to comment. As said, this was again purely based on a read of the documentation. Glad to hear you have implemented backups; you should update the docs as that is a major item.

Same goes for threads, it's still contradicted in http://dev.mysql.com/doc/refman/6.0... and leaves the reader confused.

As for the "single cache" item; I think you misread my meaning. Since a DBA can not assign separate cache/buffer memory regions to particular tablespaces, accidents like "select * from history_log" wiping out everything else in the cache and causing excessive cache misses for transactional events can still happen. Yes, a single cache in theory "spreads more evenly", but in practice, this sort of situations can easily negate that.

I haven't seen those Falcon scaling benchmarks, would love to review them. However, as long as foreign keys remain unsupported, that's a pretty meaningless comparison for practical considerations..

Optimizing Linux for random I/O on hardware RAID - Osma

Osma — Sun, 04 May 2008 22:36:45 +0300

Probably, although I have no experience with SSD devices other than USB memory sticks. Would make sense though; a battery-backed RAM cache on a RAID device is essentially a type of SSD.

MySQL Users Conference followup and MySQL's business model - Osma

Henrik, thanks for your comment. I've shared this same message directly with Mårten as well. I publish some of this stuff simply because I believe a public discourse will be even more beneficial than commenting to the sales organization in private.

I think it's the same problem like with the newest SSD devices, where the noop scheduler performs the best.

Hi Osma

I'm starting to repeat myself, but I believe it is important to highlight this simple fact to paying MySQL customers such as yourself. It is good for you to know that the sales organisation has a lot of weight in discussions on how to develop our commercial offering. This is natural, since account managers are the ones who spend time with customers and they also have a first hand feel for what features there are demand for and also what is not selling good.

So the conclusion is, writing this blog helps a little, since many in the MySQL organisation read blogs (Mårten certainly does) but an even better option is for you to make sure you mention your wishes next time you (or someone in your organisation) is in touch with the MySQL account manager.

Many sales reps don't ever read blogs, but they will have a lot of say when MySQL management evaluates which directions to go. This is all done with the intent of serving our paying customers as good as possible. Make sure you make full use of the privilege of being one.

Falcon database engine in MySQL 6.0 alpha - Anonymous

Anonymous — Wed, 23 Apr 2008 20:11:10 +0300

I have to object to "Falcon scales much better than InnoDB." Publish the benchmarks and their setups, please. The only benchmarks I've seen were not setup correctly. (Remaining anonymous because I'm not sure whether these benchmarks are supposed to be public).

Falcon database engine in MySQL 6.0 alpha - Kevin Lewis

Unfortunately, you have a few of your facts wrong here.

The current Falcon release, version 6.0.4, has a pool of IO threads that can be configured. Thus you can spread the IO work over multiple CPUs.

Version 6.0.5 has row-level backup integrated with Falcon. This release is in production now. In the mean time, you can get a copy at http://forge.mysql.com/wiki/Falcon_...

There is a single cache for all tablespaces, but this cache is by no means blocking. A hash table exists to store a pointer to each page and that short code patch is the only cache-wide serialization point. It is a very short code path, and even this will get broken up in our next release (6.0.6). So there is no need to worry about a single Falcon cache. It is actually a benefit, allowing the work to be spread more evenly across the system resources.

Falcon scales much better than InnoDB with multiple cores and with increasing connections. It still has its bottlenecks, which are being identified and fixed. But its performance has already eclipsed InnoDB on 8-way systems where the database is fully cached. And the IO performance is improving.

[ping] Acer TravelMate 6292 and Fedora 7 Linux - Fishpool

Acer Crystal Eye and GStreamer

The Crystal Eye webcam in new Acer laptops, my TravelMate 6292 included, works with the linux-uvc driver, as I noted before. To use it in GStreamer applications, you need to have the v4l2src component, which recently moved from the...

Good luck, MySQL! - Osma

For comments on Sulake's possible IPO or lack thereof, I refer to our CEO.

Good luck, MySQL! - Olav

Olav — Thu, 28 Jun 2007 13:38:43 +0300

Understand MySql is profitable and the IPO is valued at the $600m to $1Bill range, their revenues have grown consistently and they are profitable. Heard Sulake wants tp IPO according to its CEO. On the other hand, heard from an insider HABBO revenues are flat/declining, competition is fierce, its customer base getting younger, it loses money and Sulake is laying off staff. So is a Sulake IPO out of the question? Did Sulake miss the IPO window with HABBO?

Font rendering Mac OS X vs Windows vs Linux - Michael Zed

Michael Zed — Tue, 12 Jun 2007 20:11:29 +0300

Better than Windows. The font stroke width is retained in the horizontals and verticals. Is this Arial font, or a near substitute?
