because Microsoft suffered from its not-invented-here syndrome, Windows computers typically can not do WebGL because they have no OpenGL stack.
To be fair on MS, Direct3D wasn't invented there either: they bought it from another company, who had originally developed it before OpenGL was standardised. Once that was done, why would they switch to a competing product?
The article describes a system where servers are stored in what is essentially a rack laid down on the ground and filled with oil. Now, this is going to be too heavy, I would have thought, to be able to support any off the ground, so you're limited to only using the bottom 60cm or so of each room in your datacenter for server storage. Isn't this going to mean you only get half as many servers in there?
I'm starting a pool. How much longer before the mainframe is re-invented to power cloud computing. I'm taking 1.5 years. Any other bets?
Already happened. Seriously. How do you define "mainframe"? Let's look at the "characteristics" section of wikipedia's article on them:
* ability to run (or host) multiple operating systems, and thereby operate not as a single computer but as a number of virtual machines
It's quite common for any server type now to do this.
* add or hot swap system capacity non disruptively and granularly
Hot swappable components are becoming commonplace on PC-architecture based servers now.
* designed to handle very high volume input and output (I/O) and emphasize throughput computing
Modern server chipsets do a lot of I/O processing offloading in similar ways to mainframes.
The only thing in that list that isn't common on PC-based servers is "execution integrity characteristics for fault tolerant computing", which appears to be a feature only of _some_ mainframes anyway.
I want an "active windshield" that knows where my eyeballs are, knows where the sun is, and blackens just the right spot (with a little margin, of course) to shade my eyes. Compared to that, any heads-up displays are secondary.
That's really *really* hard tech. Tracking the location of your eyeballs in 3D is very tricky, especially if you're wearing glasses, a brimmed hat, or anything similar that might confuse a visual identification system. You could have special glasses that identified your position (cf the eye-mounted target selection system some military systems use), but that would probably be considered too inconvenient by most people.
Agreed. Also note that the "edge of road" projection from the pictures in TFA isn't exactly all that accurate. You could easily end up going off the road if you put too much trust in it...
Also, if he's getting JSA that means he's been unemployed less that six months.
Err.. JSA doesn't stop after 6 months. Contributions-based JSA stops after six months, which means you need to fulfill the stricter rules to get income-based JSA, but most people who aren't working and don't own their own house qualify.
The "Jedi" religion does not attempt to court political influence, and as such is only a cult, not a religion.
Actually, I think you're wrong. The entire existence of organised Jediism appears to be an attempt at making a particular political statement, i.e. that "other" religions have too much power and some of it should be taken away.
jediism is abased on a fucking movie, there is no chance that any of it is real.
Jediism is based on a movie whose author was inspired by collecting together theories of preexisting religions (particularly Zen Buddhism and Shinto) and combining them into a new system.
AFAICS, there's no chance that any of the major religions are in any way "real", but if we accept the (dubious) precept that people having believed certain things before makes them more likely to be true, Jediism becomes quite plausible, having been based on beliefs held by a rather large number of people through history.
What's a "recognized religion"? Here in the UK, the only religion afforded any kind of official status is Anglican Christianity. The only thing (AFAIS) differentiating Islam from Jediism is the number of people who claim to follow said religion.
No, you're misunderstanding the article. A "security mitigation" is something that stops exploits working without actually removing the hole that allows the exploit. Stuff like checking your stack is still intact before returning from a function in order to make stack overflow exploits fail: the stack can still be overflowed, but you can't (easily) exploit this any more.
The hole is not in the hypervisor. The GUEST OS is the one that is compromised, not the OS running the VM.
The hole is in the hypervisor; if the hypervisor worked correctly, the guest OS would behave identically whether or not it was running as a guest.
But, yes, it would appear that this flaw does not provide a way guest code can escape the virtual environment. Essentially: local privelege escalation bug restricted to virtual machine guests.
When even modern processors have single megabytes of L3 cache, and less L2/L1 cache - it will make a difference if you're swapping from that to RAM constantly.
Which will only happen if you're actually using those 11k, and hence they aren't wasted...
"This program is (supposedly) the smallest C program able to print "Hello world.". The compilation itself produces the desired printout and the program need not be actually run."
Nintendo better get a good lawyer. You know they are going to sue.
No case. The controller in question was an aftermarket add-on supplied by a dubious chinese company that nobody's ever heard of, who would presumably shrug any lawsuit off and just ignore it.
it is also understandable that a 3-year old would not know how to differentiate between a real gun and a fake one that looks similar. Sadly, it was two problems that combined to make this tragedy possible
Whether the 3-year-old can differentiate between the two or not, she'd have been likely to play with the gun anyway. Kids that age pick up and play with anything new they find. The presence or otherwise of a gun-shaped controller is a red herring; the same tragedy would almost certainly have occurred without it.
There's no way a toddler has the hand strength to chamber a round and cock the hammer.
Judging by the story, that the stepfather had taken the gun out while investigating a potential prowler, I'm guessing he chambered the round and cocked it himself. He's probably never taken a gun safety course in his life, so didn't ensure the gun was safe before putting it down.
No they didn't. The communication cost remained O(n^2), they just improved the constant multiplier, not the order. To actually bust the MM theory, they should have quadrupled a couple times more, and see whether the productivity going down the drain or is as scalable as they claim.
Indeed. Brooks noticed the problems on a team with (AIUI) over 1,000 programmers. If this company can scale up an order of magnitude or so and still keep their performance-per-programmer high, I'd love to know how they manage it.

We could discuss this further, but I'm afraid it'd be a Moot point.

Why the hell is this Exo-Blog post being cited? The author of TFA doesn't know a goddamn thing.
FTFY.
I dont know, most cd's that come out these days I'd rather burn than rip...
Having tried this with a box full of AOL cds, I can tell you you have to have a *very* hot fire to get them to burn.
That's how we know he's a terrorist!
It just seemed like too much fertilizer for such a small plot.

this was ECL logic
And there I was thinking they went straight from TTL logic to CMOS logic logic.

That's the plain-old Jedi Church. This guy's International Jedi Church, who don't appear to have a web page.

It's a great article. But it's not new.
According to the notes attached, it's recently been updated for changes in Linux 2.6.

Then sue for an amount less than £5000, where it is *automatically* Small Claims Court.
Except, AIUI, Small Claims Court doesn't hear intellectual property matters.
