It is not about being cool. Its about being productive. I've been using Unix and unix-like OS since the mid-1980s. my fingers know how to use them. I don't want to change to something that is not clearly better.
Its about making me productive.
Your boss is an idiot. Programming requires concentration. Sure, its a bit antisocial to be zoned out into music and not listening to the latest gossip about Tiger, but tough. To get into complex code, you need to think about it.
Headphones in cubieville are requied for large percentages of the developers I've known. I've been in this racket for 40 years, and worked at companes with as many as 6000 developers.
For myself, I only use headphones when I must, I prefer working from 10PM until 4AM when the house is silent and I can work without any interuptions.
The passive wheels (which are motor driven) have been around at least 15, perhaps 20 years. The general idea of heat/cool recovery is ancient. We did it when I designed HVAC 35+ years ago.
The spools have always used open sources (newspapers, radio stories, etc.) to agument their clandestine information. They have been doing this at least since WW2, and probably since the Romans.
I love the information on the vendors' sites. Its opague.
Thawte, GeoTrust and Verisign are the same, Verisigh bought them. They claim to be different, use different logos, root CAs, etc. but they are really the same company.
I did this same search a few months back and ended up buying a wildcard cert from GeoTrust. It does not do good mobile phone 'presigning" but other than that, they work fine
SIMH already emulates PDP-10 hardware, also 36 bit, with special hardware for cool things.
There is no reason that Multics can't be ported to SIMH if its not already done
The world of computing did not begin with the IBM PC and all byte are not eight bits
Dec 10s, famous at the same time as Multics, are well emulated in software on PCs.
There are many implementations, check out SIMH.
Given that DPS-8 and PDP-10 hardware were typically one mips and had under two megawords (~~ 10 megabytes) there is nothing hard about this.
Of course, I still have mine. And I've had a webpage on slide rules for at least a decade
http://www.pfarrell.com/misc/sliderule.html
Slide rule users have much better understanding of the math, they don't get off by a couple of orders of magnitude the way folks used to calculators and computers do.
Assume for a second you had a perfect server farm. Its always up, backups are made, users are added and removed, etc.
While we are at it, assume you have a staff of say two admins per shift, 24x7. That's at least 8 admins, probably more to cover holidays, vacation, etc.
In this case, their productivity is zero, they have nothing to do.
In reality, they are working their tails off, and deserve a nice bonus.
So tell the PHB that productivity is not important, its problems. Its uptime, transactions delivered, average delay on transactions, etc. Get the Users to define what the 'requirements' are, and have the sysadmins deliver it. That is the measure of what is important.
KO was a problem, but DEC died because of Gordon Bell. Bell pushed for the "vax and only vax" religion, which killed off many great computers that DEC sold, and were the key to DEC's success.
Another serious contributor to the death of DEC and computing in general was Dave Cutler, who was responsible for the terrible RSX11 operating systems on PDP-11s, which became the terrible VMS operating system on Vaxes. Then, Microsoft hired him, and he was responsible for many of the really dumb design decisions on NT.
Of course, NT spawned W2K, XP and now Vista.
The more GOTOs the better! There was a classic article in Datamation back in the early 70s
that defined the COMEFROM for folks who hate GOTO.
There was even a COMEFROM Depending upon X
to parallel the COBOL GOTO Dependinging upon AccountingCodeVariableInCobolStyle
I would have to see it. I used to design HVAC systems.
Having air around the server doesn't really do much. Back in the 70s "energy crisis" they made all the grocery stores turn up (warmer) their temperatures, and it ended up wasting energy because the produce and meat and frozen food coolers had to work harder.
If the article is just talking about cooling the CPU or northbridge, etc. then I can see it as being more efficient at cooling that components. But as a total electrical bill,
I don't see it.
Liquid cooling is more effective, but where is the claimed savings coming from?
The cooling cycle hasn't changed, they take cool refrigerant, expose it to heat, it evaporates, they compress it, spin out the heat, repeat. Every A/C in the world works this way.
All they have done is change the 'cooling fluid' from air to refrigerant.
The same heat is generated, and it has to be pumped out.
The reason IBM and others used liquid cooling in the olden days was that the specific heat of air is bad, it is better with water, refrigerant, etc. This lets them make the unit smaller
and perhaps faster. And more efficient heat transfer keeps parts cooler.
But this is not a green saving, the data center still uses the same amount of power.
Where is the journalistic skepticism?
I'm shocked to hear that the ISS provides bad value for its cost.
It was a lame idea when NASA first proposed it. It only lived for the politics of the cold war. The US funded a huge portion of the scientists from the former USSR to work on the ISS, so they would not work on selling a "how to" on making nuclear bombs to the bad guys on the planet. It worked for a while.
Low Earth Orbit has been done. It had been done. The ISS provided an excuse to have manned flight in LEO rather than doing some real science with robotic explorations of the Earth and planets.
Its not science, its a jobs program.

Rossotti would be a good choice, but why in the world would he want the gig? He wrote a book on how bad the IRS was, and he was in charge of it.
No news here, move along.
Wasn't he a friend of George Washington? How modern to use a dead guy to shill for a product.
Modern cars are obese. BMWs weigh over 4000. Its silly and wasteful. Lighter, better, faster, more efficient.
agree, this is not a technical question that needs a technical solution. The solution is marriage counseling.
Opps, then I may be wrong. Sorry.
yes, because the patch was not offered up to the openssl folks. Its pure arrogance on the debian folks, crypto can have subtle bugs.
Don Herbert's Mr Wizard was how I learned nearly everything I know. I have no idea if NBC kept them, made them available on DVD, etc.
You are wrong. You generate your request, which has your public key. You keep your private key private

Just find a new job. Sounds like your bosses are too pointy haired to live with.

Amazing. How can any professional data center be caught by this?
