I believe a "unpublished and proprietary" legend is required to restrict disclosure of information by the government under DFARS. otherwise, the details of technology supplied by a military contractor would be subject to freedom of information requests et cetera.

there is a pretty good clone of ElectroPaint too, not like the crummy one that was around in the early 2000s.

that guy is a zealot in more ways than one.

geo: your benchmark is a bit limited because it only tests the speed of incrementing, testing, and branching. in real programs memory architecture and function calling are probably more important. back in the medieval period, Dick Gabriel did some work on benchmarking systems and wrote a book about it.

these days it would be better to have more up-to-date benchmarks, like I suppose, RSA crypto or *ML parsing.

I noticed that the audio coupling capacitors in the Indigo2 like to burn up. I don't much care for the smell of tantalum pentoxide in the morning.

No, I meant a zealot , he thinks that the campus campaigns to divest from Israeli stocks are an NSDAP-like attempt to drive Jews out of colleges.

geo: I haven't read that book, let me know what you think of it.

I have never thought that the fan noise from my Indigo2s was loud or obnoxious. The old hard disks, on the other hand....
Those 50-pin disks are nearly 20 years old. The Fujitsu ones seemed to have quieter bearings, but what's really needed is a cable harness to attach recent LVD disks with fluid dynamic bearings.

One thing to be aware of when selecting SDI converters is that there are several types of data stream that can be carried on 259M SDI. A "SDI-composite converter" might be for extracting composite digital (D2) video from 10-bit serial, which is useless unless your source is a D2 or D3.
For example, this converter from AJA outputs component analog only when the source is component SDI, and composite PAL/NTSC only when the source is composite SDI.

is that made of PLA or ABS?

Do all of the color demos (Finger Of God, Spheres) work on a NuVista? I thought some of them were closely tied into the L-Graphics hw, because they did pan and zoom effects at 1280x1024. (I seem to remember that 1440x1152 was also a setting.)

Looks good!
The 3650 is a sweet machine.

hamei: looks like you've discovered the SEO industry! inserting stupid linkbait terms is what they do. Also reverse-engineering the search engines' ranking algorithm to make their sites (which as you've noticed, are worthless, but contain many valuable ads) highly ranked. The practice is not at all marginal, but forms the bedrock for the revenue stream of some of the largest sites.

Web 2.0 was specifically designed to facilitate this through its byzantine tangle of linkbacks, cross-site scripts (like the "g+", "like" or "tweet" buttons that appear in large packs on these sites, often repeated dozens of times, for each story or topic), and supercookies.

Barco is an interesting company. Always a nice touch when your computer monitor has an hour counter like an airplane :)

I believe "Print Post" is reserved for printed matter such as periodicals, what we in the US would call "second class commercial mail". It isn't available for private users.

The Dallas Timekeepers have a feature called "freshness seal" that keeps the battery disconnected while it is sitting on the shelf. The computer it's plugged into has to read a certain address in the nvram, which opens the seal and begins using up the battery charge.

This is pretty important because for a part like this "mint, low use" is not at all the same as new.

on the subject of Dallas timekeepers, anyone ever seen a DS1187? From what little I've found about it online, it should be compatible with a DS1287 but with "different battery life". Longer or shorter?

The Wayback Machine is your friend (sometimes).

Can anybody help me find DeBit-0.1 by uLogic src code?

it might be worth pointing out that in literary usage, the phrase is pronounced "battle royal". not royale with cheese.

Do you know anyone who has service information for the Reference Calibrator?
I have one that was unfortunately damaged by a noisy RGB input, and now reports "Malfunction: ELT Down".

ELT: Extra Low Voltage?? I don't know. It could also be "Limit Threshold" or something.

The most exciting new architectural feature is transactional memory.

Fire extinguishers using the same chemical seem to be priced in the range of $50-100 / kg.
I do not know if it is less expensive in bulk, it doesn't seem to be a chemical that is readily available in bottles or drums.

Ah, I thought you meant Novec 1230, which is entirely different (it is a perfluoroketone).
the HFE Novec 7000 is available in 1 gal bottles for about $300.

It might be interesting to look at cooling an imac this way, using an external heat pump

I think the posters discussing mineral oil are fixating on the "liquid cooling" bit, and not the applications that the OP linked to. The systems he described are using two-phase heat transfer, where the medium must boil to remove a sufficient amount of heat. Compared to two-phase cooling, a purely liquid phase system must have either a greater liquid volume or faster pumping speed or both ( paribus specific heat). For applications where there is a very concentrated source of heat, such as a chip with a high TDP, some kind of heat sinking may also be required. This requirement does not exist with the Intel/SGI type of two-phase cooling the OP mentioned. Fluorinert FC-72 should work as well.

There are also problems caused by a boiling fluid, as the expansion can disturb components on circuit boards. The whole assembly should be conformally coated to prevent bubbles forming underneath packages, although epoxy underfill could also work (albeit more labor intensive).

Andrew:
I just noticed that you are in Canada. You should call MG Chemicals and ask if they can provide you with samples.

You can write a shell script that calls pmset(1) and then "chmod 4755" the script.
something like
#!/bin/sh
pmset schedule sleep "$1 $2"

then "chown root" the script.

You'd have to measure it carefully using thermocouples, but IMPACT does get hot to the touch, maybe 150°F (66°C). There are icons printed on the boards that warn of the possibility they could burn you.

EISA is not the same as ISA; you can insert an ISA card into an EISA slot, but there is no guarantee that it is recognized. (That's because EISA and PCI have "configuration space" that can be probed, ISA does not). In the case of the Indigo2, some ISA cards can be recognized through special kernel build instructions. Something which may or may not be possible on a Snake.
You obviously cannot use any PC BIOS calls because none of them exist. Whatever host firmware is on the card, intended for PC boot loading, is also useless as it will never be read.
All I/O on RISC is memory mapped, there is no in/out. Any registers and memories on a card must be mapped prior to use. If these registers are all fully documented, as is the case for some SCSI cards, writing a driver is not that difficult (given knowledge of the kernel, the device type, etc). No-name ATA cards are least likely to be documented.

I think it looks bad, but the biggest problem has always been the functionality (or lack of it) of Apple products, not their look.
A number of recent cockups: Removing InterfaceBuilder and loadable .nibs, dropping Objective C, and that abortive garbage collector...

look at the FDIOSCHAR and FDSETDRIVECHAR ioctl()s. but note: "Under Solaris (x86 Edition), the configuration of the floppy drives is specified in CMOS configuration memory. Use the BIOS setup program for the system to define the diskette size and density/capacity for each installed drive. Note that MS-DOS may operate the floppy drives correctly, even though the CMOS configuration may be in error. Solaris (x86 Edition) relies on the CMOS configuration to be accurate."

I think you have to work below the level of volfs to do what you want...
From a conceptual standpoint, if you want to control the format of the floppy drive, you probably don't want automounting. Especially if you are dealing with foreign formats, mounting the device won't be possible. Just use dd.
It also looks like there are different device files in /dev/fd0*, /dev/diskette0, and /vol/dev/diskette0, not sure what difference they make

not to burst your bubble, but I don't think that is a serious price. a lot of sellers on EBay set very high prices on everything hoping to strike it rich somehow. there's no penalty for doing this, as EBay has promotions all the time to waive insertion fees.

On the other hand, the prices for old Apple gear have been rising since Steve Jobs died. I remember when you couldn't give them away, now people are really paying hundreds of dollars for Mac IIs and Quadras, and even Apple ][+'s (platinums and IIgs have yet to really go up, though).

that isn't an option, that's the built-in video processor of the O2.
if you want additional video ports, there was a device called the Carbon by a third party.

The AV1 and AV2 boards act as the analog side of the video I/O subsystem. If you take the covers off them, you find that there's not much inside; audio codec, amplifiers, video switchers and amps, and digital video transceivers. no custom chips.

the Crime chip (CRM) is like the "northbridge" of the O2. it accepts requests from the CPU and the other I/O chips and buffers them to the memory. It also contains the OpenGL accelerator component, unimaginatively called the "Rendering Engine", which is like the Indy's XL graphics (no geometry engine).
the VICE chip sits on the same bus as the CPU (SysAD bus), which limits its usefulness somewhat, since they both share the same path to main memory. Furthermore, they are not cache-coherent with one another.

I agree the VICE is neat, but it is also quite slow (I think that both versions use a 66MHz clock). And accommodating the VICE makes the R12k's interface to the system slow as well.
One thing that is intriguing about the O2 architecture is its similarity to the Ultra64 and its RCP. I wouldn't be shocked if there was unexplored potential there for graphical (or audio) emulation.

there is a lot of video software for IRIX. there are not many "free" video applications, though, on IRIX or anything else. Maybe you can look at Jahshaka.

I had been under the impression that it was just a proprietary connector, but the Hardware Developer Handbook 2.0 says:
"The 80 pin connector and pinout used for both of these sleds is identical to the new SCA
type connector and pinout used on the O2, OCTANE, Origin200/2000 and Onyx2 systems."

However, it adds that "The location of the connector on the back of these sleds does not allow an SCA drive to be
plugged directly into the connector of the Indigo2." which could mean the spacing around the connector doesn't allow for it. But it should be possible to connect an SCA drive using a ribbon cable with SFF8151 connectors at either end, without any adapters. You just need to keep the stub length as short as the cables SGI uses in its sleds.

forget cyrus, look at dovecot.

there are schemes called "forward secrecy" (or, redundantly, "perfect forward secrecy") that are designed to prevent that type of prospective ciphertext storage. the idea is that a conversation takes place in or near real-time, and after each step, the secret that authenticates the previous chain of steps is published. so once the recipient has received and opened a message, and used that step's secret to verify it, the protocol makes future authentication of the message impossible.

those machines can support OpenGL texture mapping through a software driver. Performance will be much lower than hardware texture mapping, but for 3d modeling it doesn't really matter. configurations like yours were standard spec for 3d modeling workstations running Softimage (specifically the Indigo2 Solid Impact).
When you *render* a scene, graphics hardware is not involved at all. The *rendering* algorithms are all written in software. the 3d hardware acceleration is only for previewing and interactive modeling.

I didn't find a wiki page for scsi terminators, but since they are such a simple topic, there probably are FAQs written already. Google searches didn't turn up particularly useful info though, so there might be value in a summary.

In principle both ends of a SCSI bus need to be terminated, but there are a few exceptions: when the host controller is permanently connected at one end of the bus, it handles termination at that end. and if there are no devices on a bus, it isn't necessary to terminate it. So even though the Indigo2 manual says to leave a terminator on the external bus (1) when it isn't being used, you don't have to. The Indigo2's internal bus has termination built in and no terminator packs should ever be used.

The Indy is one of the machines where both external and internal terminators need to be used, since the same bus is connected to internal drives and the rear-panel connector. Internal terminators are usually passive, shaped like 50-pin IDC plugs, and usually pass-through, so they can be connected in between the last internal drive and the cable. This is not really ideal because the drive will be on "the wrong side" of the termination, but it worked on 5 MB/s systems. On faster systems (like the Indy) it's better to either let the drive be the terminator (check the drive's manual for how to do this), or to have the drive plugged into the cable a little way from the end, and put the terminator pack on the actual end of the cable.

External terminators are usually (but not always) not pass through, and typically active terminators are distinguished by having an LED light, which passive terminators lack. It's always better to use active termination, because it adapts to different bus lengths and device loads. The Indy should always have an external terminator, when no external devices are used (because the same bus is also for the internal devices). Some external drive boxes have switchable termination, and those could be used instead of a terminator plug if you had one connected.
