...I went to Comdex and came away with a Noritake vacuum-florescent display that looked cool. The booth attendent gave me an odd look before he handed it to me.
My intention was to set it up as a system monitor, but I never got around to it. I've still got it, unused.
Now, will turbulence as seen on current commercial flights be as much of an issue in scramjet flights? You'd be passing through different conditions at a much higher speed...unless the air is a lot smoother at the altitudes scramjets work at.
With a mechanical control system? Sure. But if you slowly deaden the controls at higher speeds, the capability of the pilot to overstress the aircraft can be controlled.
Also, what's the plane doing before it goes hypersonic? Depending on how it gets up to speed, and what it does while not hypersonic, I could still see pilot control as important.
TFA: The National Aeronautics and Space Administration previously operated a wind tunnel capable of similar performance, but that wind tunnel is not currently in operation.
Also according to the article, big savings came from using vacuum at one end, instead of expensive compressors at the other. They only get short runs of about 8 seconds, but their computers can take all the readings they need.
This tunnel works in a fashion opposite most wind tunnels. Instead of pressurizing one end, they create a vacuum at the other. That means they only get a run time of 8 seconds, but they use computers to get all the data they need in that short of a time frame.
The problem comes when software vendors don't take heed of your warning that their product has vulnerabilities. The longer they sit on the information without producing a patch, the greater the chances for a zero-day exploit.
Do you really think there aren't organizations out there with similar resources to this company whose aims are finding vulnerabilities like these for the purposes of exploiting them?
If he can find it, someone else can. Informing the public that an exploit exists increases pressure on a vendor to get things patched. Joe CTO is now going to want to know why Oracle hasn't released a patch yet, and he's got millions of dollars in digital assets to protect.
Unfortunately, doped silicon is susceptible to light...each photon absorbed creates an electron and a 'hole'. In the case of a memory module or a CPU, a illumination would change the electrical charactaristics of the circuitry medium, which would probably lead to a lot of errors.
Yeah, yeah, I know you're joking. But still felt I should point it out.
I don't know a whole lot about airships, but wouldn't a big, rigid balloon hold up to gunfire more effectively than a helicopter packed with sensitive mechanics and electronics? A cloth skin would be easier to patch than a metal one.
It's not like it would pop...if they want maximum bouyancy, they'd keep the envelope's pressure as low as possible; The less mass per volume, the better their numbers.
I saw this article, and my first thought was, "Hey, this could help those people hit by that earthquake in Pakistan."
Then I noticed that it wasn't going to fly for months yet.

Try it...it's actually pretty good.:)
Personally, I like cutting out the core, then cutting the rest of the apple like a pie.

Easy...it's not the smell one is trying to communicate, it's the memory that goes with it.
"Jack's bathroom smelled like a freeway rest area." isn't intended to communicate that Jack's bathroom stank, it's supposed to communicate that if you went into Jack's bathroom, you felt you risked stepping in someone's crap. Or at least seeing some still floating around in the toilet.
The same goes with taste. You don't say, "The taste was a combination of 3 parts salty, twenty parts sweet, seven parts sour," you say, "It tasted like a lightly salted slice of a Red Delicious apple." You're not communicating the sense of taste, you're trying to recall a memory.
And if the reader has never had a Red Delicious apple, well, they don't have the right memories for the writer to evoke, anyway.
ISTR hearing about an issue they had indicting Ted Kazinsky...none of the usual methods of notification could work, so they put it in an ad in the local paper. Apparently, the court said that was OK by them.
Of course, it's a different country, different culture. But the logic behind court rulings in one country is often still valid in another country.
Conversely, it sounds like a useful "Get the hell out of the country" warning, for those with means.
But in a country whose only land border is with another country they're at war with, "having the means" means you've got money for a plane or boat ticket.
So your boss doesn't want to have to deal with bug tracking or version control...So make it transparent to him.
Put your code on a filesystem that has built-in version control, and put it all on a server. Windows shop? No problem...share the filesystem with Samba.
Anyone know of a Subversion client with a FUSE front=end?
As for bug tracking, that's probably harder. Just add that to your list of responsibilities, if it's important enough to you. At least you'll have record.

RTFA. The photo is still classified, even if the fact that it exists is not.

Ah, I see now.

I only have one vague memory of this show.
I'd want to see a preview before I buy. Maybe it'd be entertaining for my little cousins.

So, yeah, it really does suck.

900GB at 4 hours would require a data transfer rate of 512 Mb/s. I'm guessing he spouted off the numbers for his system.

I suspect something about how blimps make big, fat targets has something to do with why the military doesn't use them much.

My high school chem teacher had a bunch of chemistry-related bumper stickers above his whiteboard.
In particular, I recall "Old chemists never die, they just reach equilibrium", and "Honk if you passed P-Chem"
Never took P-chem...what, is it a particularly hard class?
Here's a fictional account.
I don't know about other filesystems, but ext2 and ext3 have had support for ACLs for a loong time.
And there's Linux kernel support for other security models.
A real zinger. Care to explain why?

It's not too much of a stretch to expect judges to order that a convict sign up for the service.
"I lost my cell, so I didn't get the notice." won't fly when the police can look at your cellphone usage records.
Well, in his case, it can be pretty simple.
As long as his boss uses the subversion filesystem, and he uses a direct client, then he'll know where changes came from, right?
So your boss doesn't want to have to deal with bug tracking or version control...So make it transparent to him.
