Dex vs Dee VM – A microbenchmark

During a recent discussion, I had the need to show some numbers demonstrating why Deelang needs the new DEX compiler. As I said in that thread, it’s all about removing reflection from the compiled classes. We all know that “reflection is slow” (for some value of slow) and especially on Android, that it isn’t generally aContinue reading “Dex vs Dee VM – A microbenchmark”

New toy has arrived!

The Royal Mail kindly delivered my new toy this morning – a shiny new Raspberry Pi. I’ve been wanting to get my hands on one of these for quite a while, but what with work and other commitments I’ve not actually gotten around to ordering one – until now. Considering the lead times on the PiContinue reading “New toy has arrived!”

DEXing Deelang – On a real device!

Further to my previous post, I’ve been working this week on the new native compiler for Deelang on Android. This is a drop-in replacement for the standard custom bytecode compiler and VM that compiles Deelang scripts directly to Dalvik Executable  (DEX) bytecode for use on the Dalvik VM used in Android. Development has moved fairlyContinue reading “DEXing Deelang – On a real device!”

DEXing Deelang – First steps in SVN

If you’re one of the few who’ve already taken a look at Deelang, you’ll know that it’s a simple scripting language that compiles to a custom bytecode format, which then runs in a simple virtual machine. It can run anywhere, but is targeted mostly for embedded devices, and especially for Android. All this is fine,Continue reading “DEXing Deelang – First steps in SVN”

Spritesheets with Gimp – An adventure in Scheme

One of the coolest Android projects I’m involved with at the moment is a new strategy game, and one of the coolest things about it is it’s retro-look 8-bit style graphics. Growing up in the 80’s I obviously got a lot of exposure to the unique look of games in the 8-bit era, and IContinue reading “Spritesheets with Gimp – An adventure in Scheme”
