That's probably not the cause of his problems, p2.
Anyway, annoyingorange, since you can't seem to figure this out on your own, Kerm should be able to help, as stated.

TI-Nspire / Re: [Nspire Entry] Falling Blocks
« on: August 09, 2011, 09:07:21 am »
Power-ups are when the player gets additional abilities/powers. They are also items that induce such powers in the player.
In the case of your game, power-ups could fall down like blocks and the player would have to catch them.
There also need not just be power-ups; you could have items that reduce the player's abilities.
An example of a power-up would be an item that makes the blocks fall slower when the player catches it.

Other Calculators / Re: OS 2.21 From Calc to Computer

Epic necropost ftw! j/k

Naw, I just wanted to say thank you to all as I did get this figured out (I found a copy of OS 2.21 lying around somewhere... :o).

New question on a related note: How do I dump the Nspire versions of the 84+ OS from an Nspire ROM/OS?  (I have very little/limited access to a real Nspire...).

Thx in advance
I'm not sure exactly how, but the Nspire OS's are some sort of archive, which can be opened with 7-Zip etc. Inside said OS is a file named TI-Nspire.img, which can also be opened with 7-Zip etc. In TI-Nspire.img is a folder named ti84, in which there are a bunch of files with names like "84rom15.bin". I have no idea how they are formatted, just that their names are suspicious ;D.
does this mean programs and apps can be [auto-]installed when the os is sent and validated?
I think critor was talking about the 83, but anyway:
Only reliably for a TI-83+, because the OS format only allows $20 pages, which is how many the 83+ has. For the 83+, programs and appvars are a definite "yes", while apps are more unlikely, given that their installation requires changes to the certificate.

ASM / Re: 68k 64-bit multiplication

With a calculator handy :P

The basic fact you end up using is that any number x can be represented in base z as ∑aizi
With the exception of when z = 0 or |z|=1, of course ;)

I'll need some time to learn a bit of C++ and look over what you've written.
Meanwhile, you could just continue yourself and see if you can get it work :)

Excellent! Finally we have a convenient way to code Lua on a computer. :D
(I mean, I won't use it, but others will find it incredibly useful :))

Computer Programming / Re: char[8] to char[8] giving error

Since when did an address become a hash? ???
Anyway, I think at the lowest level it's by address, since the following code produces an address:
Code: [Select]
class A:
    pass
print repr(A())
That, and pointers are also a special address type. Edit: not in Python, though, which, as we know, doesn't have pointers.

You could still run an OS, it would just be more difficult. You couldn't use page $00, since that's flash, making all of $0000-$3FFF worthless. You'd have to put it in RAM, cutting into free RAM.
To be honest, Venom would probably be better off porting an OS designed for z80 rather than trying to port Linux :/

Ashbad: it's the same instance if and only if it's at the same address, as far as I can tell. Note that small integers actually do act like C ints, so 5 is 5 returns True, just like 5 == 5 in C returns whatever's C's value for true is.

Most acids or bases are always in solution, and many of the more common and potent ones are colorless. You really shouldn't be drinking anything :P
I've always used hydrogen peroxide to clean out wounds, personally.

You don't use a point if you want to do it like that, Frey. And I'm not sure if the lower nibble is signed or unsigned, but I'm pretty sure the upper nibble is. Otherwise, yeah, you can do it like that.
t0xic: what speed? The decimal->hexadecimal FP conversion is done at compile-time.
Edit: 1984th post.

Computer Programming / Re: html execution in javascript?
« on: August 05, 2011, 01:48:54 pm »
XHTML is just HTML that actually obeys XML standards. That's all.
So, instead of <br>, use <br/> (or <br /> to make some HTML parsers happy).
