Now they're starting to think like a mainframer... ;-)
Re: OSv Vis-à-vis CMS
CMS started life independent of the original CP-67 hypervisor development, so it is not a good comparison. GCS, OTOH, was later developed to provide all the MVS facilities needed to support the port of VTAM into the VM suite of products. CMS maintained its ability to be IPLed on bare metal for long time, but GCS never had that ability (or need). CMS did have some MVS (and VSE) facilities including VSAM but nowhere near what was needed for VTAM, particularly multiple task support (process in POSIX-speak).
I have the beard, too (moustache isn't grey, though) and started working with VM around 1978. The VM community inside and outside IBM developed virtualization into a powerful paradigm despite much resistance inside IBM and that history is well-documented. A major pillar was the VM-specific hardware development throughout the process that provided crucial performance gains and also allowed the hypervisor to itself be IPLed in a virtual machine. To our minds, z/VM provides industrial-strength virtualization, as the number of busy Linux instances a mainframe could handle with great stability even over a decade ago testifies. In general we would like to see desktop computers get there, too, while hoping mainframe virtualization will always continue to lead the way.
This reminds me of the time some guy named Linus announced he'd just thrown an experimental, GPLed 386 kernel over the wall for other Minix users to try out. Today's version is quite a bit more sophisticated. If the fundamental concepts are indeed sound, this could prove to be a very interesting homesteading within ESR's Noosphere.
Hands Off and Hats Off
I think many here do not get the point. Unless computer controls have been developed to offset the natural instabilities of the system, you cannot let go of the cyclic when flying a helicopter unless you want the machine to rapidly come unglued. Flying a helicopter has been compared to staying on top of a ball, especially when hovering in gusty conditions. Of course, an autogyro cannot hover.
Bob Hoover is another great pilot, one who is no longer allowed to fly in the USA because the FAA will not renew his license on a medical technicality. Last I checked, however, he was still performing in airshows in other countries, still killing the engines of his Twin Commander and gliding through loops and other precision maneuveurs enroute to full stop safe landings as his signature demonstration of conserving momentum.
Re: What about the religious nutheads?
Hmmm... Am I the only one around here to notice how those self-identifying Christians are in turn picked on by non-self-identifying Christians, even to the point of being subjected to hate crimes (violently objected to by some non-self-identifying Christians) by some non-self-identifying Christians?

Re: Gravity Propagation Question
[blush] Kindly substitute "force" for "light" in the foregoing post.
Gravity Propagation Question
The force you impart to the rod propagates through the entire rod much faster than light speed, but all the molecules only increase velocity per the force imparted. This does bring up the question of gravity propagation, however. If a mass pops into space-time, is its gravity manifested everywhere in the Universe instantaneously or does it propagate out from the mass, and, if the latter, at what velocity does it propagate? Inquiring minds want to know.
He's Likely To Miss...
...the aggregate smarter infrastructure he's left behind. I doubt Dell has anything approaching what he had access to. However, it may be they really aren't expecting any great innovation to obtain, only increased customer buy-in due to his rep.
For now, only the geekiest of geeks will be working on the project. Maybe mere mortals can have a go at it around Java 9, when GPU monitors are likely to be more mainstream, wouldn't you think?
I'm interested in what the Scala crowd thinks of this initiative.

Indeed, SCO should be most grateful IBM never got their day in court. Instead, they got off relatively easily.

Re: A bit off topic but...
"And the 99.999999% are not thick, stupid, ignorant users, they are people that have more important and interesting things in their little lives than tinkering about in a forge...."
This includes Linus, you know. He's not interested in tinkering with desktops nor having one dictate how he goes about pursuing the "more important and interesting things in [his] little [life]." I believe he has made his position exceedingly plain. Last I heard he was running Linux Mint Debian XFCE. Me, too, but not because it's what Linus uses--I use it because of why Linus uses it; i.e., he and I agree on how to choose and have very similar priotities.
Re: Inductive coupling?
"Why haven't medical devices used it for decades?"
Repeat business model?
Possibly the right [pun intended] answer is "None of the above." If you want to motivate good global citizenship by corporations, you have to "vote" in the only terms they understand. Or perhaps you could motivate government to motivate them on your behalf. Unless the right answer to government is also "None of the above."
Re: An opposing viewpoint!
Indeed. And if they fell off on the Autobahn and you managed to survive, you'd likely be in a litiigious mood regarding the matter. Unless you missed the merchantability and fitness for purpose caveats in the purchase agreement, of course; then, you'd have no case.
This feature strikes me as a primordial Watson systems programming expert system. It is only advisory and can only process console messages produced by z/OS at this time. It doesn't matter if zAware functions completely locally or "phones home" to a Watson infrastructure for advice (unless the network is out, of course). IBM mainframe marketing has long considered itself hindered by the need to "install a systems programmer" at every customer site. This feature will likely grow into a crucial capability for winning new customers.
Am I The Ony Person Around Here...
...who continues to marvel how clearly John Brunner was looking into the future when he wrote "The Shockwave Rider" that was copyrighted in 1975?
And before UNIX, RSX-11, and VMS, there were mainframes with OSes in assembler, customer-developed patches and enhancements, and tools tapes put together by customers and vendors. Indeed, one of the earliest user groups (if not the very first) is named SHARE--it's not an acronym, it's what the participants DO.
It's Already On The Market
It has been for decades--it just turned 40, as a matter of fact, so it's pretty well shaken out. It's homogenized as it only runs on one architecture, but that architecture does everything (although localized KVM processing is usually a superior approach from all angles). So I'd say they have their work cut out for them unless the potential customers maintain their long-held animosity toward the proven product lines. In other words, it will all come down to marketing again.
Did I mention...
...NASA's entire annual budget is spent every two weeks or so on the ever increasing interest payments servicing the U.S. National Debt? There's another contract we ought to give to JPL.
...the longest chain of dominos the species has set up that executed flawlessly? Even the Odyssey link they dreamed up near the end that required a new twist worked out. Heck, the weather cooperated, too. They definitely stuck that landing. Oh, and that descent shot with the parachute, too.
How do we take the global financial systems away from the blokes responsible and give the contract to JPL?

Ah, that explains Yoko Kanno's "Cats On Mars" composition for "Cowboy Bebop," ah reckon.
How To Innoculate Your Firm Against This Business Model
M$ themselves haves have shown us all how. It is quite simple. Refuse to ratify all such NDA clauses in potential agreements. They have demonstrated they most emphatically do not want those 235 patents identified to the world. I believe this requirement will even trump filing a lawsuit against your less than Fortune 1000 firm. Just tell everyone the Boss is rather scantily clad from your point of view. Because he is.
Libre? What About The Appliances?
The GPL is all about not restricting the source code. If you modify it and distribute the modified binaries, you must also distributed the modified source under the same GPL you got it under. However, "appliance" computers need not distribute the source code used to compile the binaries that run inside them. This is believed to be within the letter of the GPL and apparently the FSF has no truck with this PoV. But most certainly the spirit of the GPL is, ah, compromised. Even IBM is guilty with the HMC and SE managerial appliances that control zSeries CECs. They are so unauditable the customer doesn't even know what packages are onboard. The boxes are fully networked and only the IBM Support Center can perform software maintenance upon them. The customers must take IBM's word that the appliances are completely secure and nobody on their support team can subvert their computational integrity--there is no way to audit them. But they have the connectivity to peruse and possibly interfere with just what exactly is going on in the customers' LPARs without the customers' technical staff having any way to determine if that processing has been compromised.
So leave libre out of this opinion piece, please.
"But when people gain a proper perspective of the approach to technology he has championed he will be nominated for a nobel prize."
Unless the Bill Gates of our planet buy up enough influence to quietly outlaw free software while everybody is busy kicking the champion, especially while he's down. Then MS will finally rule the Net and everybody will live happily ever after.
Security Must Be Designed In
But it cannot be if you're in a rush to mashup other people's code that hasn't even been prototyped yet (but don't worry, it WILL be secure--trust us on that).
As a sidebar, I offer http://www.networkworld.com/news/2012/052512-cloud-security-gartner-259627.html as more proof that Gartner isn't always wrong.
Re: Cell fail?
I thought IBM incorporated the needed Cell capabilities into their own processor architectures a while back.
Re: So, let me get this straight... OK, I'll help you
"On the one hand, we have an operating system with over 20-ish years of history and development behind it, that consists, essentially, of a kernel derived initially from MINIX, onto which a ton of services, tools and applications have been piled on. These were cherry-picked from the likes of BSD and its peers over a period of 10-20 years, without much effort put into making them play nice with each other."
Here's your missing detail. GNU/Linux scales. All the way down (wristwatch and probably the coming nanocomputers) and all the way up (bare IBM mainframe big iron? Sure, if you really want to, but it would make so much more sense to run tens of thousands of zLinux virtual instances under the original and still industrial-strength virtualiztion OS, now badged z/VM, because z/VM is superior to KVM). Microsoft operating systems don't scale.
I do feel a need to point out Linus used the POSIX standard to develop his kernel and the differences between kernel 1.0 and 3.0 are what you would expect after two decades of serious development. 'nix rules the networks by virtue of merit, plain and simple.
Congratulations. It's difficult for an AC to earn an upvote from me. Well said, Sir or Madam, as the case may be. And I DO have a gold and silver beard (but pure golden moustache and hair so far).
I always thought it was a little odd that IBM abandoned its 8 parallel copper data channels (the Bus and Tag cables, each 2+ cm in diameter) for a single fiber channel even though the fiber was superior in every way. So they are finally coming back to parallel throughput at fiber speeds. I wonder if slew varience is still a problem.
Re: Many years ago....
That was T.J. Watson, Sr., himself, I believe (otherwise, it was Jr.). Maybe he wasn't thinking very clearly at that time.
