Excitement Is "jsTIfied"
Posted by Ryan on 13 February 2012, 03:52 GMT

This one is hitting the news desk a bit late but is nonetheless worthy of some serious attention. Firstly, everyone's favorite international calculator superstar Christopher "Kerm Martian" Mitchell formally announced jsTIfied, a Javascript TI-83+ emulator. Yes, you read that correctly. A Javascript TI-83+ emulator. Unbeknownst to Kerm, this announcement was made on everyone's favorite ticalc.org news editor's birthday, making it sure to become known as one of the greatest events in the history of the world.

Not content to simply stir up giddiness in the hearts of the masses, Kerm delivered on his promise (as always!) and has granted access to his work in the form of a public beta. jsTIfied is an exhibition of very thoughtful project planning wedded to meticulous implementation. With tweaks and additional features on the burner, jsTIfied is a very welcome addition to the body of emulation software that so many dedicated coders have toiled to develop.

Happy Birthday Ryan. :P

I tried jsTIfied and I was amazed. It's really cool.
I also notice on TI-planet.org that they have something simular, but still in early stages though.

Anyway, Good job Kerm. :)

Early stages?
Its already fully integrated with their archive system :D
And normally it should have been online last year, but they lacked the time to do so.

I mean, it doesn't have yet any '+' support(like a 83+).

Thanks, everyone; and thanks especially to Ryan. I'm glad you guys are enjoying jsTIfied. Since I mentioned it to Ryan, I've also implemented sending every supported filetype to jsTIfied including applications, debugged a small flash glitch with Garbage Collect, and I'm in the process of supporting sending files from the virtual calculator to SourceCoder and your computer.

Wow, nice. I never thought that recent CPUs had gotten fast enough for this to be practical. Of course, I have a 3.4 GHz i5 quad—I'd hate to see performance on something like the single-core 400 MHz Celeron system I used to be stuck with back around 2005–2006. :-D

Thanks, Travis. I was worried about it running close to 100% speed when I was writing it, so when I found it running at about 300% on my laptop in Firefox, I was overjoyed.

Modern JS engines can even emulate e.g. Pentium-MMX-class x86 processors + several devices: http://bellard.org/jslinux/

To be fair, the speed on that emulator leaves a little something to be desired, though. :) Nevertheless, I'm also curious what a TI-89 or a Casio Prizm emulator in Javascript might be like.

I'm curious too. Are you planing that?

I already have my work cut out for me keeping Cemetech running, getting SourceCoder and Cemetech archives integration into jsTIfied, life, work, and my book, but if I ever get the time for it, I certainly would like to try.

Yay, 25.11 seconds to compile a hello world program!

That is, after a few failed attempts with:

hda: irq timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
ide0: reset timed-out, status=0x90
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hda: drive not ready for command

:-D

I deliberately crashed it by doing cat /dev/zero > /dev/mem. That was fun. :-)
