That's rather an amazing set of pages about the O2! It's got blurbs from Mike Nielsen, who was the chief engineer on the project, and Sanford Russell who was the product manager and is now a huge high mucky-muck at Nvidia.

I've been working on power electronics my whole career and I have no idea what these guys are doing. So it's like a filter capacitor in a power supply? When an electric motor demands a whole bunch of current, like from a clothes washing machine or an air conditioner, the capacitor dumps it's stored energy in thus relieving "The Grid" of that responsibility, thus saving you money, despite the fact that you've already paid for the energy that's stored in the capacitor? Geek warning: The energy stored in a capacitor is one half times the capacitance times the voltage across the capacitor terminals squared, and no, I didn't have to look that up... :mrgreen:

_________________

Power companies don't charge residential customers for reactive power consumption; only industrial customers. Which is why you see big capacitor yards behind companies that present large inductive loads to the grid. So I don't get why they're targeting this device to home users, who aren't charged for that load. Or, at least they're not here in the US....

I know there's more than one female member but the only one I can think of at the moment is techgrrl, but she hasn't been on since last May and she didn't renew her domain name, which was her real name (first and last). I think the reason I remember her is because she's ex-SGI. Has there ever been a poll to count how many members are current/ex SGI employees?

Memory leak. With a debug build Valgrind would probably find it in no time...

The IRIX default image viewer, followed by XV, then Photoshop, failing that I use my Linux box... :mrgreen:

bad_alloc? Seriously? The only way bad_alloc should ever be thrown, at least at this point in modernity, is if every scrap of RAM and swap on your workstation are in use, and I'm guessing that never happens......

Just checked the Mozilla cross reference to see where the exception handling routine for bad_alloc is and came up with nuthin. Is it just me or has the Mozilla codebase become darn-near indecipherable at this point in its history? And they wonder why the rest of the world picks webkit over Geko...

In the days before CGI we drew 'em by hand, this was done by some long-forgotten but obviously brilliant tech illustrator at my place of employ; the largest fully auto-loaded gun ever, the US Navy's 8-inch MARK 71, only one of which was ever made, circa 1970:

foetz you forgot to mention split screen editing! :lol:

But I totally concur, after 15 years of very active development (paid for by the US Department of Energy) nedit has just about every feature that a programmer's editor should have. And it's almost infinitely configurable by it's preferences dialog, I particularly like how easy it is to add keywords to the syntax highlighting, and how easy it is to the change colors, boldness and italicization of the highlighting.

But with that said I'm pretty sure Vital will still sell an IRIX version of Crisp if you flag them with the right number of frogskins. Ubiquitous screenshots here: http://crisp.com/main-window/

Also, XEmacs works great on Irix...

Well I did it with two different implementations of the tarai function that I dl'ed from the Internet, and they both give me 18 as the answer too: :shock:

Code:
#include <iostream>
#include <cstdlib>

int tarai(int x, int y, int z);

int main(int argc, char * argv[])
{
int myInt = 0;
int int1 = atoi(argv[1]);
int int2 = atoi(argv[2]);
int int3 = atoi(argv[3]);
myInt = tarai(int1, int2, int3);

std::cout << int1 << std::endl;
std::cout << int2 << std::endl;
std::cout << int3 << std::endl;

std::cout << myInt << std::endl;
return 0;
}

/*
int tarai(int x, int y, int z)
{
while (x > y)
{
int oldx = x, oldy = y;
x = tarai(x - 1, y, z);
y = tarai(y - 1, z, oldx);
if (x <= y) break;
z = tarai(z - 1, oldx, oldy);
}
return y;
}
*/

int tarai(int x, int y, int z)
{
if (x <= y) {
return y;
}
else {
return tarai(tarai(x - 1, y, z),
tarai(y - 1, z, x),
tarai(z - 1, x, y));
}
}

hi vish! hehe strange right? but i try your 2nd implementation and using oskars comment on using z than y, here is my output:

Code:
[13:14][blah]$ cc oskar.c -o oskar.exe
[13:16][blah]$ ./oskar.exe 98 18 12 6
mc91: 91
timespent: 0.000000

tarai_ret_y: 18
timespent: 0.000000

tarai_ret_z: 6
timespent: 0.000000

tarai_vishnu_ret_y: 18
timespent: 0.094000

tarai_vishnu_ret_z: 7
timespent: 0.000000


i guess your 2nd implementation is the best but need to change y to z.. but why? :)


Well that little trick gives Oskar's "right answer" but who knows why? It's too late in the evening for me to look at the math tonight... :lol:
