Yes, there is a vi mode (called vip-mode) for emacs.
And DOS EDIT was a dream of user friendliness compared to edlin. Edlin: for when you can't retype the whole thing in less than a half hour, so you spend 45 minutes struggling with commands.
In 1997, when I was hired at my current orkplace, only two of the PCs in use even had CD drives. They were mostly 486/25s, a few 486/33s, and mine was a Pentium PRO/233. The PPRO could not boot from CD because the CD was SCSI. (I never tried it with an ATA CD; perhaps it could have handled it, perhaps not.)
The network server was running Netware 4.11; there was an application server machine (touchtone/voice response ordering application) running on OS/2 2.5. Neither had a CD.
In 2000 I had to upgrade the OS/2 machine to Os/2 Warp 3.0 for Y2K reasons. Still no CD. Had to copy the contents over the network - thank god it had a large enough drive. (I think it's 80 mb.)
Seven years later, two of those 486/25s are still in use. Running Windows 95.
The OS/2 machine - which is an original PS/2 model 95, i.e. a 486/33 with 32mb RAM - is still running that same IVR applicaton, on OS/2 Warp 3.0. Without a CD drive.
No, it's not state of the art, but in a business you seldom need or even want state of the art. If what you already have does the job, your request to upgrade will be turned down as a waste of money.
A particle and an antiparticle both have a positive mass. The "virtual particle" mechanism means that for periods of times short enough, the measurement of the space right outside the hole is uncertain enough that there "might" be a pair of antiparticles there. So they are there. While they're there, one of them falls into the hole - it doesn't matter which one - while the other gains potential energy from its mate falling in, and escapes. Yaay.
But you can't get something from nothing. Some mass escaped from the vicinity of the hole, so some mass has to disappear from the vicinity of the hole. So the hole loses mass.
Even given that you obviously meant free as in beer rather than speech... nothing produced by Microsoft and given away for zero charge will run on anything except a Windows operating system. Providing napkins when you sell ice cream cones does not make you a paper products philanthropist.
Rest assured, these members of the judiciary, whose "actions have created confusion," will be replaced at the earliest opportunity with new, better-trained judges, who will bravely ignore this and similar heinous, anti-American rulings as they assist us in better understanding this "issue that requires clarity." Be steadfast and be proud; your unwanted freedoms will be removed as soon as we can get to them.
I have spent more hours fiddling with Rexx syntax, trying to get it right, than any other scripting language including awk. It seems underpowered and unintuitive to me. Perhaps if it was my first scripting language I'd appreciate it, but having several already jostling around in my head... ugh.
Who needs more than three scripting languages, anyway?
Earth is closest to the sun (perihelion) when the northern hemisphere is experiencing winter, and furthest (aphelion) when the northern hemisphere is experiencing summer. (In 2004, perihelion was on Jan 4, and aphelion will be July 5. [source])
Earth's perihelion: 147,000,000 km = 8.17 light-minutes Earth's aphelion: 152,000,000 km = 8.44 light-minutes [source]
What kind of attack are you thinking of? Where some guy just picks a random IP address and port number and, if that port is open, starts sending packets?
Yes. Imagine Charlie Badguy gets laughed at Joe's Hardware Store. He immediately looks up www.joeshardware.com, but decides to try to trash everything he can see in the whole subnet as well. So he does a portscan. If there's a server with common open ports, he's got new targets.
Maybe this isn't common, but it's what i was thinking of.
Anyway,... Nobody said that the knocking ports have to even be listening; the kernel could be silently recording the SYN and responding with RST.
Yes. I understand this point. My post was in direct reply to your claim that open ports by themselves do not make you insecure; a completely separate question from the system proposed in the article.
Opening up other ports, regardless of the security level of the services running on them, makes your system more visible; more visible systems are bigger targets for DOS.
If you want to pick nits, being a target for DOS does not mean you are insecure; but it's still a vulnerability.
Oooh.. let's take it further,.... IP encapsulated into port knocks travelling through an IP-OVER-MAIL tunnel which travels by X.509 going over IP using avian carriers...
(I know the X.509 probably isn't right, but it's not worth it to look it up)
"The KGB is trying to buy stuff we don't want them to buy. Let's make sure they do get stuff, but that it fails spectacularly. We know this could and probably will cause an explosion or some other disaster, possibly killing thousands. But they're only Soviets."
If people had been killed in that pipeline explosion, it's my opinion that Mr. Casey and his crew would be indictable for MURDER. Manslaughter at the least.
How do you figure? I got MORE printed pages from printing the original page than from printing the friendly page. (Well, not printed pages exactly... I sent 'em to a postscript file)
One of the things that really struck me while watching Apollo 13[1] was the scene where a dozen guys start checking somebody's arithmetic.. using pencil and paper. I realize this is drama, and not necessarily accurate (where were the slide rules, at least? Or other manual adding machines?) but it made its point, pointedly, how much we rely on accurate calculations.. even more than we do more advanced computer automation.
Hell, would you want to drive a car that was built by people without pocket calculators?
Another reason it felt more real to me is that it took me several minutes to read the article, while the footage shown to me lasted only a few seconds.
The thought that they were still alive 26 miles up... maybe aware that their shuttle was destroyed... and then the end came... I want to cry.
Reason 1 is silly. Reason 2, 3, and 4 make sense but only to prove the utility of gold, not its value. And reason five...
5. Main reason: it's reasonably rare and limited.
So is dinosaur shit.
Look, I'm not trying to seriously say that gold is of no worth in the real world. I'm just trying to say that it is worth something because people have decided it's worth something. I'm trying to draw a distinction between worth (aka value) and utility (aka usefulness). (The aka equivalences are my own, and probably imprecise or inaccurate if you ask an economist.)
You can't print more gold, it's a scarce and limited resource. But if you can find more gold, dig it up or something, the "value" of the original gold remains the same, and as you have more gold, you are "worth" more.
Nitrates used to be extremely, extremely valuable. Own a guano island and you had it made. The value was there because guano islands were rare. But fertilizers are useful, not valuable. The value of guano dropped quite a bit when artificial fertilizers were developed. The utility remains; the value has dropped.
If someone had a reliable method to produce gold in enormous quantity (a transmuter, or mining the asteroids, or filtering seawater...) gold's value would disappear. Its utility would not.
Petroleum was nearly worthless before the industrial revolution. Its value changed because its utility changed. The value was not inherent in the material the whole time; it changed because people decided it was worth more.
I know I'm beginning to wade quite out of my depth here, since I have no real understanding of modern economics. But I still think that value is what people are willing to say it is.

I'm curious: do the Windows 1.03 installation floppies still function? And do you have them backed up on some other media as well?

So that's the ultimate origin of all that "Make Money Fast!!!" spam that plagued us a few years ago.

I went every Saturday for about four years. I'd still be going if the theatre hadn't closed down.
You misunderstand.

The "virtual particle" mechanism means that for periods of times short enough, the measurement of the space right outside the hole is uncertain enough that there "might" be a pair of antiparticles there.

How's that for handwavy?
Even given that you obviously meant free as in beer rather than speech ... nothing produced by Microsoft and given away for zero charge will run on anything except a Windows operating system. Providing napkins when you sell ice cream cones does not make you a paper products philanthropist.
You can think of it (in mathematical terms) as a mapping of R^3 onto itself which expands distances.
An analogy that may help:
Take a circular rubber sheet. Draw some dots on it. Pull the sides of the rubber sheet and watch the dots separate.
Now imagine your rubber sheet started out as an infinite plane: it is no more infinite after stretching than before, yet all distances have increased.
Now generalize from an infinite plane to an infinite volume, and you should get the idea.
Destroying a lock may be easier than picking it, but it is not the same thing. It earns more booty, but less kudos.

Seriously, though, your local home supply store, which sells hardwood flooring, will have wood putty and similar products to fill such scratches.
If you don't want the easiest way, you can always sand down the entire floor and re-finish it with polyurethane. Ugh.

Any chance this could be adapted to sea life? There's a hell of a lot of gold dissolved in our oceans...
Thanks for the correction... been a while since I've seen the movie.

Gold is intrinsically worth nothing, either. In a community where there is a famine but everyone has plenty of gold, just try swapping gold for food.
Value is a mental concept, not a physical property.
