Oh and another strange behavior, it seems i lose a router link when second test starts... Doesn't seem to affect the system, but it always shuts this link down each time it starts the second test of the run2.sh

That is indeed very strange. There is no network-code in the program.

For a little bit of extra performance, consider the enclosed patch to chromewave's makefile.

Thank you! I see, there are many compiler switches to explore.
Does the -IPA switch bring a decent performance gain?

Nice to hear that it works now!

Although the use of LD_LIBRARY_PATH is controversial.
(Google for "LD_LIBRARY_PATH bad")

Hello,

I have an external DVD-Rom drive (HP C4315A) that I want to connect to
the Octane.

The Octane-side is no problem, but I don't know what connector I need
for the drive-side. Below is a photo of the port on the drive.

The port looks like a centronics port, but it has 68 pins and is smaller,
but it's NOT a "VHD centronics plug". I have already two cables that dont
fit.

Has anybody a clue what kind of cable I need?

Best regards, Martin

recondas wrote: As it was explained to me, that drive wasn't intended to be connected directly to an external SCSI cable - but inserted into a chassis that provided the other half of that connection. There's a blue lever on the bottom of the DVD-ROM case that was used to cam it in and out of place into that chassis.

Thank you very much! I was wondering what the blue lever is good for.
Looks like I have to do some handicrafts.

Best regards,
Martin

I sawed a hole into the backside of the case and connected the cable
with an 68/50 pin adapter to the drive.

The DVD-rom drive works fine now with the Octane

Thank you again,
Martin

Thanks to Geoman for testing.

You're welcome!

In 1982, I saw the game "Rip Off" at a funfair. Since then, I wanted to do a remake.

I hope there are no problems with the game. It was testet on my Fuel (V10) and Octane (ESSI) and
Geoman's Octane2 (V12). The game should run on any Octane/O2 or better. It uses the SDL instead of
GLUT, so you need the Nekoware SDL.
(only the basic SDL is needed, see "readme" on the homepage).

Best regards, Martin

I've been banging my head trying to figure out why this script will not run. All files have been unpacked into the same directory and have full permissions. However, upon execution it keeps coming back with frects0088.txt cannot open. And a few lines saying not found but I'm not sure what that is in ref to. I can open the .txt in an editor so it's not corrupt and I've replaced all the files several times. It's probably one of those silly simple things I'm not aware of yet...Please help...

Welcome to the forum - you start with a "big iron"!

What happens if you just type ./run1.sh
(without the leading "sh"?)

Greetings,
Martin

jaezeen wrote: ./run1.sh is what I started with but that returned me a command not found. However, success! Since I'm not that practiced at console I thought it would be easy to unpack the tar file on a windows box, I then burned the files to cd and dumped on the Irix box. Something must have gotten lost that way. I burned the untarred file onto disk and and with a little reading in the man pages unpacked on the SGI and then everything worked. However, it seems to be only using primarily one cpu. The first run was on 4 and then the second on 6. So the times where pretty slow? Thanks.

Some programs (e.g. FTP-clients) change the line-endings of textfiles. Looks like this happend
while unpacking.
Windows uses a different encoding for lineends (0x0D 0x0A) than Unix (0x0A).
Most Unix-shells don't like the Windows lineends. You can tell if a file has
Windows lineendings by opening it in the vi-texteditor. The text is full
of "^M"-characters in Windows-textfiles.
I have a tittle tool ("unixlf") to convert windows-textfiles to unix-textfiles.

About the speed: try to run "run2.sh". It seems that Irix doesn't uses all CPUs when an
application is running too short. Unfortunatelly, I don't have a multi-CPU SGI. The
program was developed with a Phenom-Quadcore and Ubuntu/64. With Linux, all
CPU-cores running full speed from the start.

Martin

Experiments starting with those conducted by the scientist Dr. Ernest Rutherford using alpha particles show that atoms are mostly empty space.

So in simple terms are we compose of 99% space as well? Any scientists in the midst to clarify this?

Cheers

But what is space? What is matter?

Everything is a kind of "forcefield", interacting with other forcefields (or not).
The atomic nucleus is a forcefield and so are the electrons that belong to
to atom. And between them is another forcefield.

I'm not a scientist, but that's my explanation : )

Would've thought you guys would have a thread about this up and going already, what do you guys think?

There is a rumor that the only difference between a professional graphics card (NVidia Quadro, ATI FireGL) and
a consumer-card is the BIOS.

So, theoretically, you could upgrade a cheap Geforce-card to an expensive Quadro card just by
changing the BIOS.

sybrfreq wrote: edit again. neverball/neverputt is doing it too!

Hmm. Both programs "thiefs" and "sslow" use the SDL-library, and so does Neverball (i guess).
Looks like there is an issue with SDL on your machine.

Do you know Inkscape?

Please, no beginners stuff It should really be up to date - I most certainly don't want to replace it next year [but then again, my PS/2 still creeps along fine - not sure that everyone on here remembers the times when there where no personal computers at all and you still could purchase milk in glass (!) bottles]...

Every new iMac you buy today is powerfull enough for every "normal" office task.
The new iMacs have already "Sandy Bridge" Intel CPU and AMD HD Graphics,
so they should be sufficient for at least 3 to 5 years.

Which one you choose depends mainly on which screen size you want.
New iMacs have either 21" or 27" displays.

P.S. you can still buy milk in glass bottles (at least in germany)

Used it in the past. Start-up company, no money, QT was still commercial.
It was a nightmare. Implementation was inconsistent or even incomplete across platforms.

We use QT where I work now. It works very well. The last QT version supported on IRIX is 4.5.

I don't like wxWidgets too. It looks like a bad MFC-clone.

If you have a small project and only need the user-interface, go for FLTK.
If you have a huge project and need network, threads and stuff, go for Qt.
If you have a game and only need OpenGL, sound and joysticks, go for SDL.

All of the three work on Windows, Mac, Linux, Irix (at least).

But it looks like something designed by kindergarteners for kindergarteners So if "cross-platform" means everyone is reduced to a five-year-old, QT gets the nod

You never used Qt, right?
We use Qt for large cross-plattform-projects and it works great.

A friend of mine has a kindle (without keyboard).
It's much better for reading books than the iPad. Because of the passive display, you can
read even in the brightest sun and the letters are very sharp.

I also saw a keyboard-kindle at a local dealer (Karstadt).
Although the keyboard is quite small, typing works good.

What the kindle really misses, is a touchpad. Especially when
your are used to an iPad.

BSDero wrote: Hi all!!

Is this data type uint64_t supported in O2, and previous SGI machines?
I'm trying to so something portable across SGI machines, but I´m not sure if this is supported in old machines.


Thanks in advance, guys!!

If uint64_t is supported depends on the compiler, not on the machine.

If you use uint64_t with a 32-bit-compiler, the 64-bit-arithmetics is
emulated with 32-bit-commands.

BSDero wrote: What if I'm building a kernel module using uint64_t in a Fuel/Irix 6.5.30?

It's compatible backwards to, maybe O2 with 6.5.x?? Would it run on this machine?

Will be binary compatibility at kernel/driver level?

Thanks in advance guys

I have no experience with building kernel modules. Are you building
a 32- or 64-Bit Kernel?

If you use the "-mips4" compiler-flag (I asume you have the MipsPro-compiler),
the generated code uses the full MIPS IV instruction set, which is supported
on R10000, R5000 and R8000 systems. O2 has a R5000, AFAIK.

Yes, I know they are posers.

When you call "changeInt(myint)", a copy of myint is made.
When you call "void changeArray(array)" a pointer to array is passed to the function.

That's why the content of the array is changed.

BTW:

The Cube-Demo I made some years ago is still online. There is also a 3DS-Model
of the cube.

I wonder what Operating System Tim Berners-Lee would use today.

OMG I started a flamewar!

I don't care if Mac OS/X is a "real" Unix. Unix is not the holy grail. As long as I can use
all that Posix-stuff and do "./configure, make, make install", it's Unix enough for me.

Another demo I wrote a few years ago is the "Cube"-Demo:
