We’re involved in a dozen or so open-source projects, but our three core efforts at the moment are […]

Partially OpenSourced

Reading evening news and rss feeds I found interesting next sequence: Jeremy’s post “MySQL to launch new features only in MySQL Enterprise” basically about some new features of MySQL will be available only for paid customers Then Kaj’s post Anthropology: Sun studies MySQL with tagline “Sun didn’t acquire MySQL to change it, but to learn […]

Back from OpenSource Database Conference

I’m just back from OpenSource Database Conference and PHP International Conference which took place in Frankfurt. I’ve uploaded slides for two talks I’ve been giving which you might want to check out. In general Database portion of the conference was a bit boring. May be because it was not widely announced or may be for […]

eWeek tests OpenSource stacks and .NET

Have you seen recent eWeek benchmarks which test OpenSource stacks and compare them to .NET ? Here is what was compared and here are results. Results make me ask number of questions – why WAMP would perform 6 times better than LAMP ? Why Python would be faster than PHP on Windows but slower on […]

InnoDB memory allocation, ulimit, and OpenSUSE

I recently encountered an interesting case. A customer reported that mysqld crashed on start on OpenSUSE 11.2 kernel 2.6.31.12-0.2-desktop x86_64   with 96 GB RAM when the innodb_buffer_pool_size was set to anything more than 62 GB. I decided to try it with 76 GB. The error message was an assert due to a failed malloc() […]

Traditional close source company often develop product in the secret and when it comes out as a surprise for computers and making a big […]
