• Is Groovy dying?

  A few years ago, on my Computer Science MSc, there was something of a mini-revolt as some of the students – already working as developers – complained that the object-orientated design course was being taught in Groovy – a JVM-based language that, in effect, is a dynamic extension of static Java. They said there were […]

• C, C, glorious C

  This blog – The Unreasonable Effectiveness of C – is really very good, and makes a lot of points that are very difficult to argue with. Though, lately, I have (re-)discovered the joys of C++ – even if I do write code in that language like a C programmer. In the last six months I […]

• Is Groovy back in fashion?

  Last year I was taught “Object Orientated Design and Programming” as part of my Birkbeck MSc, using Groovy, a dynamic functional language built on top of Java and running on the Java VM. I enjoyed it and liked Groovy – I went on to write some pieces of software for my MSc project using it. […]

• More poor performance from the Open JVM?

  My, expensive, and meant-to-be-fast server became available today and while I would not hesitate to recommend Hetzner – the people I ordered it from, the performance is disappointing. I don’t think the issue is the box itself – it has 12 cores and 25 GB of RAM. Instead the issue seems to be the code […]

• Performance collapse in the Open JVM

  Unfortunately, I do not have time to investigate this further myself, but others may do. But yesterday I had a serious performance issue with the (open) JVM – though I was able to solve it with an algorithm change – swapping the problematic (integer) code for a lot of floating point maths: not the usual […]
