Still using HP-150B from 1984 with Shugart HD (SH412? I don't recall at the moment), Seagate ST506 and 2 ea HP9133XV drives. They're very loud... Also have a dead HP150C. Used to have a HP2000C/F Option 205 w/ a Teletype ASR33 & TI Silent 700 portable. And IBM keypuncher. (Still have a portable keypunch.)
Also still have a ProLog STD-Bus card cage with Z80 board, a Conner 20Mb IDE drive in it. Still used as a BBS under CP/M, from 1986.
Still have a CBM +4 or three and a C64, also used occasionally.
And have a real IBM 5150 PC wrapped up in storage, along with old Toshiba hard disks and Shugart floppies and minifloppies, plus a few of the original Sony microfloppy drives from early 1980's.
I plan to hide a PC104 586 system in a HP150C case. Nice retro look with enhanced brains...
Got off the phone with a "rep" with an Texan accent about being soft-slammed by them, switched to biz LD service.
Had to be American: his "conversation" was peppered with all-American racial innuendo and insults and the air was thick with "I'm the expert and therefore superior to you, moron" attitude.
No Indian I've met had ever come across like that. No, Indians are more civilized, it seems.
That and SBC's emulation of NYNEX (non)service makes me want to go totally wireless...
Now we can patent prior art and things in the public domain! I'm collecting all my stuff I released to public domain right now and get a muckeysaft lawyer and patent them all!
Someone who knows better believes that certain machines which used hydrogen would cause a massive chain reaction, if it ignited, with every other similar machine all exploding more or less simultaneously, turning the entire SF Bay Area into one huge crater.
Despite his knowledge to the contrary and other evidence, he clung doggedly to this fallacy and was terrified by the presence of the machines. (I suspect it was really just a scheme to get out of work.)
SO it is not surprising that the less educated fear hydrogen in the same way.
Lets see.. what else... Hydrogen ignites spontaneously. Any concentration will oxidize (aka "burn") in atmosphere. Very low concentrations will not produce enough heat to be a hazard and can generally be ignored. So tiny leaks from storage containers, as long as they are not enclosed, are relatively safe. Generally, if it is able to dissipate faster than it is leaking, there will not be a problem.
Hydrogen rises and can be trapped where it will spontaneously ignite, often with a sound like firecrackers or someone dropping steel bearings on a tin roof.
Metals can facilitate ignition even where the concentration is below the lower explosive level.
Hydrogen dissipates extremely rapidly. COmpared to, say, methane, the concentration drops off more rapidly with distance from the source. Were you to release a quantity of it in the center of Wash. DC, within a quarter-hour some of it would be past New York City if it hasn't already oxidized.
Hydrogen does move upwind. But since it dissipates so rapidly, this is not a problem, except for hydrogen detectors set to scream and shut things off before the concentration reaches 50% of the lower explosive limit.
A small hydrogen flame is invisible in sunlight. Large quantities are more visible, with orange to blue flame, as the nitrogen in the atmosphere also burns--yes, it gets that hot!
There have been no "mushroom clouds" from hydrogen leaks.
A vehicle crash will not result in release of the hydrogen all at once if the cylinder is damaged.
The hazards of compressed hydrogen gas are well known. The cylinders are used and handled very carefully and are well maintained. It is also well-known that most car owners would neglect to properly maintain the gas cylinders. So there will be no compressed gas cylinders in hydrogen fueled vehicles. It will be made as idiot-proof as economically possible.
There's nothing quite like tuning into rtty, tweaking the demodulator til the cross appears and listening the beadle-beadle of the signal while watching the asr23 do it's thing.
Such a beautiful sound as the motor hums, the solenoids pull the bars and the print head smacks the paper--or the tape.
Spent some long winters in the shack kept nice and cozy with all those tubes and motors going.
Even the asr33, though it doesn't sound the same, is sweet. But it is an ASCII machine--7bit plus parity.
in case somebody might wonder, 5-bit is called Baudot. It has been in use since at least before WW2. It is still in use! Has one start bit, two stop bits, totaling 8 bits.
Baudot is also used for deaf tty's ("hearing challenged" for the politically impaired).

No. straight glycol first came to mind. But heat pumps and exchangers also come to mind.
A water leak would be a really bad thing to happen to a computer. Water systems inevitably corrode and leak, esp closed loops. It is not a pretty sight. Or smell.
open loop systems, faucet to drain, are for the rich with their own private water supply.
Water systems must be inspected and maintained.
But I would really like to adapt a CryoTorr-120. Just need a case big enough for the displacer, head and pipes. And polyphase power.
Would like to see how fast it can go when cooled to 20K.
Deja vu all over again or just predicted?

Network Blackout
·
· Score: 1
The graphic makes it appear as if the network outage propagated outside the blackout area.
Reminds me of a white paper with just such a scenario published somewhere around the time of the Morris Worm.
The paper warned that the entire Arpanet would come down if such outages started to propagate outside an affected area.
Perhaps too much trust is being put into tcp/ip's ability to route around failures?
But anyone who is too bloody damned lazy to adequately maintain a liquid cooling system of any sort deserves whatever leaks out and the consequences thereof.
What??? Don't want to do maintenance? then don't get it! Got it?
Whomever bought the license from SCO seems to have screwed themselves as far as the GPL if they ever intend to distribute any part of their GPL's software.
Since they have made an agreement with SCO by buying a license, they now seem to be subject to the restrictions in section 7 of the GPL and are apparently now obligated to not distribute.
But this also could be yet another big fat lie by SCO. And the more brazen and outrageous the lie, the easier it is believed.
So far it seems as if SCO is all bluff and FUD.
Seems like IBM is going to nail certain balls to a certain wall. They do seem to have substantive facts, while SCO has evidently presented none. So IBM is likely gonna rip through them like a skilsaw through a jock strap.
But is it not obvious that the power lines would be a big, huge, enormous antenna array which would radiate the entire broadband spectrum applied to it, plus harmonics thanks to various defects and attached equipment, etc., adn.?
I suppose no one wants to go there.
Power lines already emit too much noise and interference. Why add more?
Seems most people are totally ignorant of and oblivious to anything that is not AM, FM, TV, FRS, good-buddy CB or wireless phone.
Wake up people! There's more to the world than you think.
This appears to be a resurrection of the slidewalk of mid-last-century, as found in some airports. It seems to be shorter than those. But is is an experiment, after all.
Did Asimov write a tale about slidewalks? I do not recall encountering such.
Robert Heinlein wrote a short story The Roads Must Roll! in the 1950's about huge slidewalks that crossed the nation like interstates and which had segments with variable speeds to allow people to get on and off safely, without a lot of acceleration. Even so, accidents happened, including fatal ones.
Heinlein's short story appears in an anthology with several of his other short stories written at about the same time. (sorry, I do not recall the book title.)
did somebody's reality cheque bounce?
Long, long ago, when solar sails were proposed, they were intended to use the mass emitted from the sun to move them along and it was clarified that they were not intended to use light which they said would not work.
In the past few years the discussion of solar sails has been revived but has been focused exclusively on using light to move them.
So what has changed? Has some miracle occurred whereby radiation has become better than mass at pushing these big sail thingies around?
Perhaps we've been totally wrong all these millenia about using sails to catch the wind at sea, as well?

Use base60, Babylon style. Like Roman, no numerals.
They should just use the Really Big Book of Baby Names to name the stuff.

Then I'll settle for 200K...
Probably wouldn't get there anyway. Unless the pressure was taken below 0.5Torr. And then the electrolytics would turn into popcorn...
Be nice to the die; it's been through hell and back just to become a CPU for you.

Not in california where the ballot serial number or the number plus a known offset is recorded next to your name.
