As I usually do around this time of year, I took a much-needed one-week vacation from work at the beginning of May. With my recent scaling-back of the rosco_m68k project that’s been getting all my free time for the past couple of years, I needed a fun project to do during my time off, andContinue reading “Why I used my vacation to write a Java assembler”

Getting the most out of 16KB ROM!
Lately I’ve been doing a lot of work on the rosco_m68k hardware, specifically on integrating the new Yamaha V9958 video board. As part of this, I wanted to extend the firmware to support basic “virtual consoles”, so that if a V9958 is detected it will use that for text output, or fall back to theContinue reading “Getting the most out of 16KB ROM!”
Generate less bytecode with default methods
Java’s default methods (introduced back in Java 8) are one of those features that solve the intended problem reasonably well, while at the same time allowing all kinds of nasty code and weird inheritance stuff when used in a general-purpose kind of way. Indeed, they’ve been the subject of a ton of posts and theContinue reading “Generate less bytecode with default methods”
We all love to use mocks in our Java tests, right? Add the usual mock framework to your test dependencies, sprinkle a few mock, when and thenWhatever calls in to your code, and happy days. You’re able to test things in isolation, and as an added bonus ensure your code is actually calling the stuffContinue reading “Mocking v2.0”
Curb FFI – FFI port of Curb
In the meantime, I’ve also started work on porting (if that’s the right word) Curb to FFI, with a view to moving away from the existing C code.
Deelang 0.20 released!
After about a month of coding (on and off), The Deelang DEX compiler is now feature complete, and what better way to celebrate than by releasing the code? It’s always been available in Subversion of course, but now you can download all the new stuff from the downloads page as either a source package or ready-madeContinue reading “Deelang 0.20 released!”
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”
Deelang – First file release available to download
After a few months in Subversion, with a few folks playing with the code and seeing what use they can make of it, the first file release of Deelang is now available from the project’s downloads page. This release is still a very early public release (as denoted by the 0.18 version number) but isContinue reading “Deelang – First file release available to download”
