Twitter has finally hit mainstream, it was bound to happen and with Ashton, Oprah, Shaq, among many others it’s now going to be around for a while. This means a lot of interesting things for twitter such as scalability to handle this new massive growth which will be much more regular unlike the more sparse spikes they would see before. But as user of twitter it means something far different, it means twitter is about to run out of usefulnes....

Functions take parameters. What order should these parameters be in? Perhaps a bit of a ridiculous question, given that it clearly doesn’t matter. void writeUser(Connection c, User u) { ... } void writeUser(User u, Connection c) { ... } If one writes either of these functions, they will both work, and any performance differences between the two would be an extreme micro-optimization which wouldn’t be platform independent (e.g. in RISC ..

Warning: MySQL `LOCK TABLES` command does an implicit commit

The MySQL LOCK TABLES (and UNLOCK TABLES) command has a nasty side-effect. It implicitly commits the current transaction. This caused a bug in production code (a normally irrelevant temporary error, which should have normally caused a rollback, only rolled back to the last UNLOCK TABLES command due to its implicit commit, and thus left the database in an inconsistent state, meaning that when the request was retried the software found the ....

Java’s slogan was “write once, run anywhere”. They received a certain amount of criticism but I have to say that compared to other programming languages it’s really true. You can use it for: Background jobs (without user-interface) Server-side web applications (many web servers & web frameworks available) In the web browser (applets) In the web browser (translation from Java to Javascript by GWT ) On the desktop (using platform-independe..

People sometimes ask how come I know so much about Oracle (and some Unix) internals and how do I have such a passion for these things. Also, another thing you may have noticed is that for some reason a large amount of hardcore computer hackers, low level troubleshooters and various internals experts happen to come from Russia. And I can answer why this is so! A little bit of history: I am an Estonian, was born in Estonia and lived ove..

Thanks the the internet archive I found one of the first (or one of the only?) websites I designed i.e. I did the graphics, did the “implementation” using a tool which produced HTML, etc. (Although the company logo etc already existed, I didn’t write the texts..) This was for AAA+ which was the first company I worked for in my life, which was also the company I worked for just after coming to Vienna, so has a lot of associations of newnes..

I came across this problem at work and also over on this www.stackoverflow.com thread . You have a directory and you want to recursively zip it up. Simple, right? The equivalent of the unix command "zip myDir.zip myDir". Should be like 5 lines of code? Python even has a built in zipfile module, sweet! Well, as is often the case (see urllib and friends), python's "batteries included" slogan is more like "enough batteries for 36 seconds incl....

SQL is a declarative language – in other words you just declare what needs to be done and Oracle takes care of the part how it’s done. However there’s nothing declarative about the actual SQL execution when it happens. SQL plan is just a tree of kernel rowsource functions executed in a specific order (defined in child cursor’s sql area). The root of SQL plan is where the fetch function (opifch2 for example) gets the rows for passi....

See the previous post for background and first few games. One thing I noticed about central Wellington is that nowhere at all does a show sell any sort of can or bottle of soft-drink for less than $2.50 , I suspect it’s some sort of cartel of shopkeepers agreeing not to compete on the price. … Continue reading North Island Champs – Easter 2009 – pt2

Second, these are strictly my personal thoughts and opinions and in no way represent the experience of my team or anyone else. Third, my project ....

During my spring cleaning, I ended up getting rid of my AS/400 model 9404-D10 from 1991. Since the power supply is dead in it, I decided to disassemble and photograph the inside of this amazing machine. AS/400s are well known for their legendary uptimes, and were the “jewel” of IBM in the late 1980s to 1990s. In 1993, when IBM was close to splitting up their divisions into smaller companies, Bill Gates said that “the only part of IBM th..
