ahh I had a feeling it would be that video. Anyways what I've noticed with most schools is that they'd rather just punish everyone instead of investigating the incident because they're too lazy or lack the resources to do so.

experiment with OC'ing eh? Yeah, ive done it be4.. and its not *that* dangerous. I've even overvolted my gpu to the max which is by default a locked function in afterburner but you can do it . and also that didn't really solve my freezing problem when i played it again after doing it. After it crashed crysis from overclocking too much, I decided to then on utilize benchmarking programs not to benchmark, but to find stability in my overclocking to get it where i need it.
Oh and also about more ram, theres a problem.. My cpu air tower is so big, it actually covers 2 of the ram slots effectively leaving me only with 2 available. Its not the tower itself, but the fans attached to it. Its the corsair A70 cpu tower.
Oh one more thing.. the motherboard i got, it overclocks to 4.2 GHz with a press of a button, so that will be easy if i decide to do this.
I meant more like overclocking can be dangerous if you don't know what you're doing but you seem to be quite skilled in this. For me it is very dangerous when I mess around with my memory clock multiplier ratios because if I don't increase the voltage sufficiently the computer will crash instantly and won't turn back on. The only way to fix it is to reset the bios setting which is a hassle. And for the ram, these days 4gb often isn't enough especially if you're running games such as Crysis 2. Because of issues with the cooler's size you have two primary options for upgrade. One you could buy a new cooler in which I would recommend one from xigamatek because they are quite effective and take up little room on your mobo (note: they are very tall so check your case size to make sure it'll fit). After that you could then buy an additional 4 gb. The downside is that not only will you be getting rid of your current cooler (something I always hate to do with perfectly functioning hardware) it is also probably the most expensive option. Second plan is that you could buy a pair of 4 gb sticks and put those in place of your current two giving you 8 gb total. An advantage here is that if you later decide to change your cooler, you will have 2 more available slots for future use (16 gb anyone ). The issue though is that you would still be retiring your once again perfectly functioning 4gb of ram.

It looks like your probably low on memory. Best thing to do here would be to buy an additional 4gb of ram which is best done if you get the exact same model as your current 2 sticks. That will most likely fix the problem and if not you could experiment with overclocking. For the cpu and memory do all your edits from the BIOS as that gives you the most control and for the gpu use either MSI afterburner or ATI catalyst. Both provide very similar functions. But before you try any of this get more memory first because overclocking can be dangerous!!!

We also need to modify the header files from both SDK's to have proper #ifndef blah_h, #define blah_h, #endif statements so that other libraries don't end up being accidently included twice once more third party libraries become available.

hmm I got 24,000 words. I'd say fairly good for my age. What I would like to see is a french version of this so I could test how well three years of french classes have taught me.

That is very impressive! How many colors are available for shading?
There are 8 base colors to choose from but up to 3 can be combined to create numerous shades. If for example only what shade of blue is used, the result is light blue. Two shades of blue will create standard solid blue and adding a third blue will do nothing. But if you add 2 blues and a red, that creates a dark purple for example. Using some rough math I was able to calculate a grand total of 127 colors but someone else should check this though as it may be incorrect. Edit: or if you only use 2 shades the total is 36 colors which I've already confirmed

Ey! What just axe for Prizm, there is Fx-9860GII too! :p
Well the problem is that most Casio developers are either Prizm or 9860g exclusive. Added to that is the difficulty of porting the compiler over as both calculators have extensive technical differences that would need to be addressed. I for one do not own a 9860g and have no intention of porting any axe like language to it as that is not my area of development.

I don't think the syscalls should be organized by number as it has little relevance to its actual use. A good way to have them organized could be by the library file each is stored in such as "display.h". But for the time being I'll see how well I can get the current list filled with important information.

Very impressive. I see quite a bit of potential there. I would also recommend playing around with dynamic graphs in BASIC but the drawback is that you can only have one graph at a time and once the animation starts running, the only way to quit is if the user presses the ON key which ends up causing a break error. Hopefully though there is some way to fix this. btw you might want to replace your batteries soon

That would really be great if we could get the wiki updated. I believe Jos Juice currently is the wiki admin and controls all of the major changes. In fact what I had in mind for the syscalls page was an organization system similar to wikiti.brandonw.net so that full documentation could be provided for each call. Right now the only syscall documentation is just copied from the .chm and is geared more towards asm coders and provides little insight to those who code in C. What we'll need in the discussion is an explanation of what each call does exactly, what all the args do, the use of the return value, ram locations destroyed, and how to effectively use it in a program.
But then again we aren't as reliant on syscalls for the Prizm as we were on the 83+. So far the only reason why I use a syscall is to draw the screen or depending on the program draw text. But they will become more important in the future as we start experimenting with some of the hardware such as the usb.

Casio-BASIC: make as many tables as you'd like but have no way to remove old ones because you cannot draw with the color white

C++ relies on the existence of the standard lib for the target platform. Since the Prizm doesn't have a fullly [implemented] standard library, not all C++ will compile for the Prizm.
That reminds me, once I can get my first release of Walnut out I need to start working on newlib. On the documentation page there is a list of OS subroutines that newlib relies on, with many of them not being too hard to write. For the more complex routines such as multi tasking, newlib provides default routines that just specify that the feature is missing while allowing all the libs to compile properly still.

1 ) Yes, it can work with fractions. The calculator doesn't handle them perfectly (odd decimals are occasionally not recognized), but it does a pretty good job for the most part. 2 ) If you set the options properly, yes. You can also disable much of that. 3 ) At present: BASIC, C, brainf*ck, and ASM. In the future, probably Lua, Java, C++, Groovy, Khavi Scripting Language (and derivatives), etc. 4 ) Yes, although I can't remember how in-depth it is. 5 ) There are a few programs out there. It's not a TI-84+, but there are people working on it. 6 ) I like mine. 7 ) I have *tried* to crash mine and it's extremely difficult, even in ASM. The worst that normally happens is that you reset the calc, which rarely causes data loss. 8 ) BASIC programs, yes. C programs, not as easily.
I thought we could already code in C++ or is the linker not done yet? Because PrizmSDK comes with an sh-elf gnu g++ compiler but I haven't used tried it yet. Most of the time with C I compile with the -std=c99 option because it provides all the C++ features that I need such as inline code, asm, and // comments.
