Hmm. That would be interesting to look into.
I'm sure a few of us might like their iron running off converted three phase.

Didn't find coverage of the conference in a cursory search, but I did find this article covering a visit by CTO Dr. Eng Lim Goh with the Greater London LUG a couple weeks later in London. It doesn't seem like a bad piece in terms of what "SGI" appears to be up to these days. Perhaps it's not unfair to say this -- that SGI's brilliance was in making complex and difficult things much easier to accomplish. For most of their history that was graphics, animation, visualization and video/film. Nowadays they may still be making the complex manageable, just with respect to single-system-image clustered computing.

Nice to hear someone say something mildly positive about today's SGI, even if I might quibble with one or two things the article's author wrote.

I'm now taking bets on how long it will take for someone to piss all over the current strategy. Oops - never mind. I read the comment thread on the Inquirer article. Looks like people already have that covered. Still, it was nice to read some favorable coverage for a change.

Wrote on the subject of What are people doing for Classic support now? at June 15, 2010, 10:28 p.m...

I do a little bit of all of the above.

I still use my 12" 1.5 GHz G4 running Tiger for 80% of my personal computing, but the growing lack of support for Tiger, particularly by third party vendors, has me thinking that I will soon update it permanently to Leopard, obviously dropping Apple's Classic environment at that point. Fortunately, my use of Classic has been plummeting over the past couple of years.

For really old MacOS software, I mostly use my SE/30 running MacOS 7.5.5, or I use Mini vMac on current hardware to emulate a Mac Plus running MacOS 6.08. Mini vMac is actively maintained, and the developer says that a version capable of emulating a Mac II is on the way. Mini vMac has been ported to a lot of platforms, and it's definitely worth a look for preserving access to Mac Plus era software.

I have a Powerbook Duo 270c running OS 7.1.1 and a Duo 2300c running OS 8.6, but I rarely fire them up. The Duos are tiny enough that they are never in the way. I also have a nicely tricked out PowerBook 1400c (dock, RAM upgrade, external video card, all by NewerTech, and PCMCIA ethernet and modem), which IIRC is configured to dual boot OS 8.6 and 9.1.

As I will likely move either to Leopard or finally migrate fulltime to my MacBook Pro, the idea of running SheepShaver to maintain access to Classic apps has a lot of appeal. I've only tinkered with it so far, so I can't comment on how good or bad it is for routine use. I haven't tried Basilisk recently, but that's only because I haven't had time, not because of its quality.

Wrote on the subject of List of SGI CDs at June 30, 2010, 7:19 a.m...

Building a catalog of the basic 6.5 discs, including overlays, has been on my "to do" list for a while. I have nearly every overlay in my collection, and I think it would be super useful to have a database of discs in one place.

What I'd really like to do is to include a list of packages (and maybe even the target destination of installable files, although the output of that would be pretty huge) on each disc, too. It would be a little tedious, but it would involve feeding in each disc, issuing the "showprods -f <dist directory>" and the "showfiles -f <dist directory>" commands, and then parsing the output for database import or wikification. Maybe this summer...

That said, a simple part number list sounds like an excellent idea for the wiki. No reason we can't get started on that right now! Time for a little crowdsourcing?

While my inner architect is screaming, "Database! This has to go in a proper database!", I fear that if we wait for that, it won't get done any time soon. (The perfect is the enemy of the good. Pick your cliché.)

For now, let's just get a basic list on the wiki. Including, at a minimum, part number, disc title, and optionally the date as a separate field. It's a wiki, so we can always clean it up and de-duplicate records later. Not elegant, to be sure, but I'd rather see data published than not published.

At a later date, we can add links to detailed pages for the contents of particular cds, or we could build the type of database that jan-jaap suggested, which I think would be the "perfect" eventual solution.

What do you think?

AFAIK MS Services for UNIX was never released for PPC. It also doesn't run on NT 3.5 or 4.0. Back when it was Interix maybe, but the MS version requires XP or newer.

You have an unusual piece of hardware there. Why you'd want to turn it into a rusty peecee running an outdated version of Windows is well beyond me.

In the same way that I usually recommend avoiding OSs other than IRIX on SGI MIPS kit (though I don't begrudge people who want to experiment with them), I suggest sticking with AIX on the ANS. Especially when trying to raise an old system from the dead, I prefer to do so using the OS that the machine was designed for first.

As for MS Services for UNIX, some quibbles, I know, but here we go:

SFU 1.0 required NT 4.0 SP3 on x86/Alpha
SFU 2.0 required NT 4.0 SP4+ or Windows 2000 on x86
SFU 3.0 required NT 4.0 SP6a, Windows 2000, or Windows XP Professional on x86
SFU 3.5 required Windows 2000, Windows XP Professional, or Windows Server 2003 on x86

Emphasizing: any version of Windows 2k worked with SFU 2+, but only the Professional version of XP was supported on SFU 3/3.5.

Wrote on the subject of Windows 2000: Retiring July 13, 2010 at July 5, 2010, 7:45 a.m...

Those of you who have systems running Windows 2000 might want to check for any last updates this week, as Microsoft will move all remaining flavors of the venerable OS from Extended Support mode to Retired mode on July 13, 2010.

In other words, Microsoft will no longer officially support Windows 2000 after next Tuesday. While some support material will likely remain on the website, there are no guarantees about what will remain or for how long, so be sure to download any necessary patches, service packs, and security fixes if you actively run W2k. (Microsoft indicates that "self support" materials will remain for one year after retirement.)

General information about Microsoft lifecycle policy is at http://support.microsoft.com/lifecycle/

Microsoft's Windows 2000 End-of-Support site is at http://support.microsoft.com/ph/1131

EDIT: Somewhat more detailed info about what goes away on July 13 is at http://support.microsoft.com/gp/lifean46

I wonder how many IT shops there is out there that are still running on 2003R2 instead of 2008 ?

At least there is a little bit of time left to plan a W2003 migration, since most flavors of Windows Server 2003 are under Extended Support until July 14, 2015 .

I suspect that you are not alone in continuing to run W2003. W2003 seems to be one of those "good enough" products that make the cost/benefit of upgrading to a newer version less than obvious.

Silicon Graphics SGI Octane + detritus - $25 (san mateo)

For sale - the last remnants of my former career at Silicon Graphics, featuring the enclosure (but not the electronics) for the Octane workstation (excellent condition), a set of clear feet for the Indigo2 workstation and the original machined prototype for the feet, the wristwatch that the CEO gave all the employees in 1993 when we reached a one billion dollar revenue run rate, two stupid Indigo2 Extreme colored cloth tubes intended to be worn as hats, and best of all, the Octane Soundtrack CD, featuring the hit single "Ignite Your Mind" and Octane Love Song. No wonder their main campus is now the Googleplex. Years of hard work and dashed hopes all yours for the miserly sum of $25. Act now and I'll throw in some old SGI graphics boards and a CPU from (I think) the Indigo2.

Well, honestly who is actively looking for IRIX vulnerabilities? And why would they even bother?

All you need is one open door, and if compromising a vulnerable IRIX box gets you through that door onto a local net, then it may well be game over. The IRIX box is not necessarily the target, but the vector, and in an age when botnets control cpu power and bandwidth that were once the sole province of governments with supercomputers, adding a probe for a set of IRIX vulnerabilities does not have to be a costly proposition.

Yep, the ability to slap a couple of terabytes of USB storage with relatively low power requirements onto an IRIX box for less than $100 without having to worry about glitches or gotchas would be terrific. Unfortunately, I doubt that we're going to see that happen.

As an aside, I use a 10 Mbit/s Challenge S as a bridge between my two home nets. Works fine, and it still has more bandwidth than my backup DSL connection to the internet. That said, I probably will update to a faster bridge, since my cable modem connection to the internet is nominally 20 Mbit/s. I'll keep the Challenge around as a print server, however. Just because...

...and I guess that's the bottom line. While most or all of us would love to have access to full USB compatibility (or Firewire, too, lol), there are few, if any, of us who have the necessary combination of time, skill, motivation, and knowledge of IRIX internals to make it happen. I wish it weren't the case.

If someone does manage to do it, they will be praised to the hilt, but that's pretty much all that they are likely to get for developing a USB driver for a platform that last saw a newly manufactured machine four years ago and that will be unsupported in two years. Anyone with the requisite skills to do it would be able to do something much more profitable with their time, so it would have to be a real labor of love.

A safe way to do it with minimal coordination effort might be through Kickstarter - someone proposes a fundraising project with a budget, people make pledges to the project via Amazon checkout, but no money changes hands unless the project is fully funded. If the project doesn't get fully funded, no one gets charged anything. I'd be willing to pony up some cash.

A musical acquaintance of mine used the mechanism to fund the manufacture and distribution of her latest cd - pretty neat, actually.

You'd need to find an SGI "PCI Card Cage" or a PCI to XIO adapter (also known as a "shoehorn") and then add a PCI USB card, assuming USB drivers could be developed. See viewtopic.php?f=3&t=16720341 for ideas about other PCI cards that work in an Octane.

The hardest part is the driver, which does not yet exist. The hardware to use PCI boards in Octanes does exist, but may not be easy to find in Brazil.

It's slightly more complicated than that. The O2 outputs both a Sync-on-Green signal and a standard PC H/V sync signal via the HD15 port. Apparently, some/many non-Sync-on-Green monitors --even high quality ones-- fail to filter out the sync signal from the green channel , so while the display is basically usable, the output has a heavy green tint (not a gamma issue). True SOG monitors are probably the safest choice for an O2.

After the recent Gawker.com password fiasco, I've been refreshing many of my accounts with a range of new passwords.

I didn't think that I'd be affected by the Gawker problems, since I don't remember ever signing into or caring about the site, but it turns out that they own a bunch of other sites and use the same authentication system for all of them. I made a comment on one of them, Lifehacker.com, years ago, and I used that username/password pair on a bunch of non-essential sites, so my credentials were compromised.
