On Decompilers and Obfuscators

The guys at Minecraft Coders Pack have done a great job at lowering the entry barrier for Minecraft modders. Really.

Decompiling Java programs and recompiling them again has never been a real problem. However Minecraft is also obfuscated so that all class and method names are replaced with short meaningless labels.

Most obfuscators deliberately try to generate code which while still functionally identical to the original is as confusing as possible for a decompiler. This includes generating bytecode which can not be produced by a Java compiler or adding dead code with illegal functionality in hopes of disorienting the decompiler and forcing it to give up.

The decompiler used by MCP suffers from all this and is in fact not able to correctly decompile all the bytecode. However MCP uses a set of patches to help the decompiler where it has given up. These patches are updated manually for every Minecraft release.

Where MCP really has succeeded is at the returning of the meaning of the decompiled code. The MCP community has reverse engineered almost all of the Minecraft source and while some places are not quite right and one or two are totally wrong the final result is quite comprehensible.

MCP also includes the tools needed to recompile and reobfuscate the changed source so that the final result is compatible to the original Minecraft bytecode.

On IRC #mcp on irc.esper.net there is even a bot which can report the current deobfuscation mapping and accept names for the missing entries.

One just can not wish for more.

In the beginning was the Fog

Minecraft has always looked foggy, even on Normal and Far render distances. And this has always annoyed me a little.

The fog was robbing the vibrant colors of the valleys and mountains and turning them into washed-out background panes. Switching the render distance was also changing the fog density which was breaking the illusion of seeing a natural world.

Being a Java programmer since ever, I naturally came to the question "How hard could it be?".

This is how OptiFog was created.

Cavalcante rediscovers winning ways at Dream 15

Gesias Cavalcante got back on the winning track at Katsunori Kikuno's expense.

Two of three judges favored Cavalcante (15-3-1) over Kikuno (13-2-2) today at Dream 15 in Saitama, Japan. Cavalcante recorded his first victory since September 2007.

Cavalcante hadn't fought for more than 13 months after a loss to Tatsuya Kawajiri in May of last year. For the first several minutes he appeared to hesitate against Kikuno's mixture of strikes from Kyokushin karate, an unusual style in mixed martial arts.

But Cavalcante took down Kikuno multiple times in the opening round, and he spent most of the second stanza smothering Kikuno on the mat. Cavalcante took his back in the last two-and-a-half minutes and stayed there almost until the end, although Kikuno regained his feet just before the bell.

Kikuno has lost two of his last three fights, with the defeats coming against men with the wrestling and grappling to bring him to the mat and avoid his karate attack.

Today's result marks a strong return for Cavalcante after suffering through injuries over the last two years. He had a wrap around one of his knees for today's bout.
