The problem with REBOL being an OS, is that REBOL programs are still interpreted, rather than (JIT) compiled. This means that computation heavy programs are not really feasible (e.g. decompressing a music stream (such as MP3 or OGG) on the fly).

Carl has a partial solution with REBOL v3, by way of a portable assembler, but your not going to want to use that for more than tiny sections of code that get used heavily.

I assume the main reason for avoiding JIT (so far) is that it is simply a hell of a lot of work for one single CPU, and REBOL is all about being portable. So maybe it'll happen eventually, if REBOL become popular enough to justify it. Or perhaps Carl should just port REBOL to the Java VM, and let it do the hard JIT work

This is the function I am using (from latest public SDK):

The latest v52.3 version I uploaded to OS4Depot today should have working NSD64 support. If you could try it out with your filesystem it would be appreciated.

Thanks for that. I'll try it out if I can find/make some smaller DVD iso files to test with.

Re: Post #8

Is this merely a speculation, or do you have a reliable source? If so, how much can you say in public?

There were bugs in the large file support, for example image files > 4 GB didn't work with my CD/DVD burning tool, but I currently don't have free HD space to create a SFS2 partition for checking what's wrong and fix it, therefore it's removed.
There was no interrest in it anyway, AFAIK the only programs in which large file support was added are lha and DvPlayer, both done by OS4 developers or beta testers who didn't need SFS2 for testing the large file support in their software.

NSD64 is only half of what you need, the image file has to be accessed using 64 bit offsets as well. OS4 final includes the 64 bit dos.library functions, but IIRC they were not in the last public SDK yet. You'd have to write custom functions using the old, 32 bit dos functions as workaround. That's of course possible, but it's more work.
If the 64 bit dos.library functions were not in the last public SDK yet and the new diskimage.device is for AmigaOS4 only I could sent you a small link library with some 64 bit functions, but if you want to support AmigaOS 3.x as well you'll have to write your own functions based on the old 32 bit functions anyway.
I have another file system with 100% working large file support, if you sent me a beta version of diskimage.device I can test if it works correctly with files > 4 GB.

Quote:
IIRC the ICD0 mountlist included in the old, m68k versions of diskimage.device is ok (a lot of it is for CacheCDFS, but it's ignored by CDFileSystem and doesn't cause problems). You just have to make sure it includes DosType = 0x43443031, LowCyl = 0 and BlockSize = 2048.

@salass00

Nice work, really appreciated!

@salass00

Screenshot showing a new feature that will be in the 52.3 release of diskimage.device (write protection):

PS it appears AMIGA Inc has been in contact with Carl (fingers crossed - this could be exciting).

@goody
when I first read this, I had not been on the REBOL site for some time. Just in the last few days I have been back and have read more carefully and I think you are on the right path with this, and it is very exciting.

Very important to look up the Wildman Project to quote:

"is a "secret project" that examines the question: what is the minimal environment for running REBOL? Can REBOL operate natively on specific hardware, and if it did, what components would be necessary to be successful? This project will begin early spring. Complete development will depend on our results and possibilities for potential funding."

AmigaINc apparent break with TAO had me very worried as I have had a long interest in VP technology. That Bill announced a way of getting cross platform abilities without TAO intent, made me think they were going for static compiles.

On the other hand, a stripped down AmigaOS compiled for different HW platforms, add in REBOL, a few statically compiled plugins and we really do have something looking like OS5 and a lot more beside.

It would not be AMIGA as we know it, it would be better.

AMIGADOS as a REBOL script, might be possible (REBOL calls written in the compile). The rest of AMIGADOS stripped right back to the bare essentials - and REBOL creating an application environment - this has many exciting aspects including the networking of IOS.

PLUS, if this is pulled off, the effect would be revolutionary., in terms of application size, execution and constancy across platforms. The trend to bloat would be hit hard with truly tiny efficient code that packs plenty of punch.

@AmiDog

That's too bad. AFAIK there are no alternatives to use files >4GB? I was looking forward to trying out this feature. Guess I will have to work on other stuff for now...

@salass00

I think there were some issues with the 64-bit support in SFS2 and thus it was removed.

edit: This thread should probably be moved here.

I can't find it on the SFS page anymore:
http://strohmayer.org/sfs/

I'm going to need a filesystem capable of handling files >4GB if I'm to test the mounting of DVD images with diskimage.device (I have just implemented NSD64/TD64 support but have yet to test it).

Also any suggestions on DVD mountlists for me to try/use would be appreciated too.

@Curty

U know Curty, I was gonna jump this thread & say stop talking about cakes

You're not kidding, the skinnable interface really is something special. The creative people really will love playing with xml.

FuZion.

@Mikey_C

TuneNets looking good here,
Ummm the skinable interface!!!!
It rules!!!

@Chris

That depends innit? if Bean gets it out before next ANT/ABW meeting, I'll bring the Choc Gataux there. its on Sunday June 10th

@AJS

Phew! That probably means I didn't miss the cake.

I'll make more of an effort next time (only three weeks until the next one anyway - short month)

But if Mikey's not bringing cake I might not bother

@Sister_Rita
...
You shouldn't discuss that in public, i think.
Use PM
ssolie: You are correct.

Sorry I missed the point of some of the things you are asking about.

I was thinking in terms of LAN/wifi streaming. There are ways of doing what you want, but they are bulky at best and quality might become an issue.

Basically you would need to have a cable out to a RF home TV transmitter (I have seen none yet that could deal well with HDTV, but that might only be a matter of waiting. If your TV is old, cheap transmitters can be bought. I currently use two switch boxes together to redirect three cable pictures to the TV - it is primitive but it works (as I have Foxtel, a DVD player, HD receiver and PS3 all going into the one monitor).

Ideally, and it is what I am thinking of doing over time, is to have a dedicated server, and use the PS3 as terminals where you need them (hence the price has to become modest).

If AmigaOS got onboard and Sony wanted close integration, given what already happens with PSP, it should be possible to stream games from the PS3 to a computer as a screen

@AmiKit

You have done brilliant work, please keep it up. Using an emulated environment keeps "the home fires burning" and when the idiotic hw/court situation clears there will be more potential users because of your (and to be fair, others, who allow the use of their SW) extrordinary efforts.

I had Amikit running on X 86 Ubuntu for a while (under E-UAE) but I screwed around and lost it, I had about 95% working, the killer was the startup scripts which I started to play with when I added my bought SW.

It almost works on AOS4 -E-UAE but there is a memory leakage problem with the latest version but evilrich is aware of that so maybe it will be sorted in later releases.

What would be brilliant is if some of those tools and programs could be updated to PPC but maybe that also is not really needed, it would just be nice to move away from 68k dependancy, although once again if it does work who cares.

You couldn't have studied 2 more profound areas and be an Amigan!!!!!! Good luck in you chosen profession.

@Sister_Rita

Yep.

The PS3 uses wifi to stream movies and games to the PSP.

In terms of monitors vs TVs the convergence with HDTV means no practical difference.

In terms of business, the machine can be booted in the otherOS mode and the GameOS need never be seen.

It is very versatile.

As a fixed architecture, when the prices go down over time, it makes an excellent and stable business machine (business is not all that demanding on HW for the most part).

It is no replacement for desktop computers, but the rub is that often a desktop computer is over kill for what is required. The fixed architecture makes maintaining a computer network much easier.

There is a real opportunity, to side step a lot of legacy-ware in the business community, over time, simplify computer deployment and do so for a good many years.

Personally, when the time is ripe, and the costs diminish, I would like to use it as a standard student school computer (instead of a big box, it could be virtually mounted on a sturdy LCD stand).

When the price falls to less than 75% of its present cost, it will be an easy choice in a lot of areas, not the least in the home.

As a teacher, if AmigaOS was available, with a few more apps from the Linux world, I would have no problem recommending it to parents as an ideal student computer, not the least because it can also play games.

Sorry for my ignorance, I am not too informed of these technical details: Is there a possibility to direct the PS3 video output to two devices at the same time?

Is was thinking of this: You want to see movies and play games, but also use the PS3 as a serious business computer.
In this case I'd need to connect it to my television AND to my 19" computer monitor. Is this possible or can the video output be streamed over the air?
When I am programming or using text applications, the television from my living room is not the best choice and makes my eyes bleed.
