Axe / Re: lines/text
« on: September 17, 2011, 10:03:11 pm »
The "window settings" in Axe are 96 wide by 64 tall and go from (0,0) in the upper left corner to (96,64) in the lower right. You can't change them because those are the physical dimensions of the LCD.

I doubt it will ever be approved by Sun/Oracle. I'm just making it somewhat compatible with the Java Virtual Machine specification.

Okay, it's been a whole two days (::)) since I posted on progress.

As it turns out, there were a few things in the old Java interpreter that didn't quite mesh with the official Sun spec, so I'm in the process of fixing those. I'm also going to be doing garbage collection a bit differently and I've started on the beast that is memory management. There will be a repository up sometime in the near future as soon as I get the project approved.

Miscellaneous / Re: Political party?

What is wrong with that? The reason people do that is because a political party has beliefs that people agree with (like Spyro and I with the republican party).
If a party shares the beliefs you have, why not devote yourself to it?

Because if devoting yourself to a party causes you to compromise at all on your beliefs, it's a bad party to devote yourself. If joining a party doesn't change your beliefs, then it's rather useless as a political party. So you're basically left with parties as social forces, which is pretty idiotic as a democratic system (although very sensible as a republican system).

And Very Easy Game..I couldn't finish it it was too hard interesting :P (tho it's easier than the original, the original gave you only two years to react while this gives you three)
No. The unexpected change of the time limit will leave most players confused for at least 1½ year, which makes it harder to react in time. :P


There's actually a bug in the program that means you have infinite time to press the button :P

Other Calculators / Re: TI-Nspire 84+ emulator - hate it.

* Qwerty.55 remembers a prototype generator he built. It cost him $300 to machine the parts for the thing.

I remember ExtendeD talking about how they had an exploit, but they didn't want to publish any information on it until they had a second backdoor to exploit in case TI cracks down.

It's cool to see that the Prizm uses a more modern display, but I've always been curious how older LCD's worked. Thanks.

Here's the current source for the context switcher. It's mostly completed, aside from a single call to the [currently unwritten] scheduling algorithm.

Yeah for now the goal is to get it back into its state from before the hard drive incident and also worry more about backups in the future :P

 I set it up with a repository for more permanent storage as well as a directory [on a different server] that auto-syncs with all of my major project folders.

Thanks for the concern everyone.
