Other Calculators / TI connect being a huge *****
« on: October 06, 2010, 04:36:56 pm » I am...with a problem with TI connect.

I cannot switch to TiLP right now due to some unfortunate...circumstances (ie I have no administrator privileges on this computer)

Anyway whenever I try to send/recieve ANYTHING from my calc, I hear the "usb device removed" sound effect and then TI connect throws an "device cannot recognize the command" error. It has worked up until yesterday-ish, when I uploaded the Cuberunner update. The only things that have changed was the addition and use of CalcSys to/on my calculator.

OS: 2.53MP (yeah I know)
Windows 7

After this error message appears, on my calculator screen appears the black, downward facing arrow character in the uppermost left corner while the cursor flashes over it. Attempting to type anything onto the homescreen results in a shutoff and a RAM clear.

Any ideas?
Thanks in advance :x

EDIT: restarted computer, and it worked fine (lolwut)

Miscellaneous / any scouts in here?
« on: October 05, 2010, 04:44:21 pm »
I seem to remember a few people (finaleTI for one?) mentioning they were scouts and I was wondering just how many we have here :P

No pressure if you don't want to say, just a fun little topic

Also I'd also like to know if you went to the 2010 jamboree...and what kind of patches you got. it's always fun to share stories ;)

Today my calc teacher started off the class with a pop quiz, one of the questions of which has been a source of contention among my classmates and myself....

wow gotta lay off the ap english lol

anyway here is the problem:
f(x)={ 3-x  x<1
       { ax2+bx   x≥1

Find the unique values of a and b such that f(x) is continuous

so what i did is I used the definition of continuity:

f(x) is continuous at c IF


a(1)2+b(1) = limx→1-f(c)=limx→1+f(c)

This is where I stopped. Some other people have told me that in order to find unique values, you have to make f(x) differentiable at 1 as well. I say that the question never says that that is necessary, so the correct answer is that there is no answer (or more accurately, any a and b such that a+b=2). Differentiability implies continuity, but continuity does not imply differentiability.

Who's right?

So apparently it got DDoS'd today.
My initial reaction: LOL

Anyone know any details?

TI Z80 / Axe Cuberunner
« on: September 22, 2010, 03:48:15 pm »
My next project will be a psuedo-port of the itouch game, Cuberunner!
For those of you that don't know it, it's a simple game where you attempt to navigate through a course full of cubes, without hitting any of them.

Attached is a screenie of my current progress as well as the nostub exectuable. The current version is in (almost) full 3d. The square size and position is done with 3d math. However, they are only squares lol as opposed to cubes. I am probably going to keep them as only squares anyway, and will also probably move to scaled sprites as well for speed purposes.

Currently there is no collision detection and the 3d is a little glitchy, but that can be fixed ;)

TI Z80 / Space Dash rerelease, help with v1.2
« on: September 19, 2010, 05:01:20 pm »
hey guys, here is v1.1 of space dash (my contest entry, only with now most of the bugs fixed :D)

I need a little help with a planned 1.2 though, so I posted this poll; I need to make sure the difficulty curve is adjusted right, so please input!

Also, I need help with the last bug that I deem important enough to need fixing: when your ship passes through the background stars, they disappear. Here's what my code looks like right now:
Code: [Select]
[black part of ship]->Pic1A
[gray part of ship]->Pic1B
Repeat Q
Horizontal -
Horizontal -
Horizontal -r
I can't figure out any way to do this without changing everything around....

For those of you that haven't seen this game in the Axe Contest thread, there's a screenie attached.

Bugs Fixed since Contest Release:
random death upon starting game
screen vomit for split seconds between rounds (thanks, shmibs)
spikes/other non-explodable objects cannot be exploded by bombarding them with lasers anymore

SPACED is the nostub executable, SPACED2 is a MirageOS executable

edit: gif runs a little slow in chrome, btw

Computer Usage and Setup Help / computer issues
« on: August 19, 2010, 05:51:10 pm »
Ok, my computer as of late has been acting extremely odd and I was wondering if I oculd maybe get some help here...

At random times it emits a beeping noise, then turns off. The screen simply goes black. Upon turning it on again, Windows tells me that it was shut down incorrectly, etc.

I would first suspect overheating,and then a faulty power supply or weary heatsink. However, this computer is less than 8 months old. And it's a laptop (which I would expect that all of its parts

Specs: HP Pavilion Dv7-3000 laptop
4 gb ram
nvidia geforce 1 gb
intel i7 1.6ghz

ummm can't think of any other things that would be important right now....would a company really build a laptop with a faulty PSU? bah idk what to do...

Art / Converting bmp's

is there a way to convert a 24 bit bmp to a 8xi file?

ASM / 64bit windows
« on: July 04, 2010, 11:15:15 am »
In short

I tried starting asm programming

64bit win7 doesn't support TASM/devpac8x

Does anyone know of any good assemblers that are compatible w/ 64bit win (or x64 version of devpac8x)

Thanks in advance :x

k so basically I was wondering if proof by induction is valid if, for the first step, you prove for x=0 instead of x=1.
Using domino logic, it's really a matter of whether you decide to start counting from 0 or 1 (which is where I got the idea to ask you guys....;)


Axe / Sound in Axe
« on: June 11, 2010, 08:50:59 pm »
I was wondering if anyone knows which frequency arguments for SinReg correspond to the traditional pentatonic scale's notes

like to play a C, what value would you use and then how much would I increment to value to raise it a half (or whole) step?


Axe / Curve-fitting
« on: May 30, 2010, 01:57:08 pm »
~~~~axe is smexy~~~

anyway, i'm working on a version of tanks (scorched earth) and I'm wondering if anyone has any ideas on a routine for map-drawing. Smooth, random curves with varying amplitudes and periods: I was using the sin( function, but its epically confusing, what with the period being 255, etc
