Try Heimdal . It uses it's own lib to convert kerberos v5 tickets to AFS tockens. In my setup with a simgle kinit I get v5 tickets and v4 tickets.

Anyway, AFS *can* use Kerberos v5. The initial configuration can be a bloody nightmare though...

KTH is just sucking up his ass in any way they can, even by giving him a honorary doctorate after Linus got it from Stockhom university, KTH's rival (Slashdot covered Linus).

It's all in the money.

Since you have never studied operating systems, you will probably not understand this. Still, I will give you what you ask for. The NT Security FAQ contains large amounts of information on the Windows security model.

As for the effectiveness of the security model, look at the number of Windows exploits that were along the lines of, "To get this task done I had to give him that level of access, which he used to screw up all sorts of things." I assure you it is less prevalent than on UNIX systems, precisely because of the better security model in Windows.

Of course, you won't find that on bugtraq. They don't report problems with the security model unless they are due to clear bugs in the security protocols. So you can't make the comparison without research, which obviously isn't your strong point.

As far as root exploits go, a well secured Windows system doesn't even have a root user or equivalent. Can you understand that, smug in your little UNIX world? So in that sense Windows can be made to have no potential root exploits. Not that it matters if you have a bug that allows you to gain arbitrary priveliges.

I guess my real point is that you shouldn't spout off ignorant drivel when you don't know what you're talking about. You should keep quiet, or learn about the subject. I suppose that is too much to ask, though.

Missing from this list is the biggest space structure I've ever heard proposed, the solid Dyson sphere, a modification of a concept proposed by the astronomer Freeman Dyson. A solid Dyson sphere is a shell constructed around a star, so that all the star's energy is contained. One of these built around the Sun at the radius of the Earth's orbit would have a diameter of 3x10^8 km.

There's an episode of ST:TNG in which the NCC-1701-D crew finds Scottie marooned on the surface of a Dyson sphere, where he has trapped himself in a transporter loop for several decades in order to survive.

Hey, give me a billion and I'll make a couple for you and we can get off of this fusion chase, and start generating useful energy. From the sun. Like the rest of the Earth.

I don't have a billion, but I can give two pointers to neat ideas of how to harness the power of the sun most efficiently.

The first I read about many years ago: Dyson spheres.

The second I was pointed to by someone replying to a post of mine about Dyson spheres: Matrioshka Brains.

Enjoy!

Wow, when I saw this picture I was like, "This seriously needs anti-aliasing." Then I realized that it wasn't a line, it was window shades.

LetsGoDigital is going to fry any time now. Mirror available here.

Please use, I'm measuring the Slashdot effect. (Seriously! There's no such thing as a karma whoring AC.)

Link directly, gawddammit!

Here's a slightly better one.

Slashdot them to hell. It's my university, they can take it.

Pretty close. This is a reasonably (if fluffy) overview of the history of Taligent/Pink and the relevance of NeXT in the story. Interesting read. The mid-'90s were quite a time in OS/computer development. Back when things were still exciting, as I see it.

This link to an online book on the history of the Telegraph has a similar (identical?) account.

More interesting (to me anyway), is the text of the actual letter to the Scots' Magazine which can be found here.

Both describe the system as using individual wires to which would be electrified using the spark from a Leyden jar, and depending on which wire you electrified, you would know which letter was being represented. Much of the decription could be used to credit CM with the invetnion of the telephone pole as well, since he/she describes how the wires would need to be suspended and insulated at the suspension points.

Curious though, is that it was originally identified as means for transmitting intelligence, yet the plan for constructing it was published in a magazine - an early proponent of Open Source I guess.

The second link also indicates that work on electric was performed as early as 1746 coinciding with the invention of the Leyden Jar itself, so I think the current Scotsman article may be a bit biased when it claims this CM is the real inventor of electric telegraphy. And that in the 1780's a system was proposed that would have used either a 5-bit or 6-bit 'binary' system for sending the signals over fewer wires - by having different combinations of wires signal each character (ie 00001 = A, 00010 = B, 00011 = C, etc.)

Looniness is quite natural for me, I don't mind at all. But the explanation is entertaining, so I'll share with you. (Hint: negative evidence is still evidence)

Carl Sagan said it better than I ever could. The Drake Equation posits that by now, at least 100 (or anywhere from 5 to 50000, depending on your assumptions) electronics-capable intelligent species have existed in our area of the galaxy so far.

So where are their radio signals? Their space probes? Why does SETI strain fruitless to discover any kind of extraterrestrial signal?

The possible explanations are that there either never was any other intelligent life, or that it lost its ability to send radio signals and space probes shortly after acquiring it. (The Dyson Sphere is another possiblity. So is the Prime Directive, and plain xenophobic paranoia.)

Look at the technology level on earth today. We can already send probes out of the solar system. Given this ability, within 100-300 years at most, we'll be flinging a capsule laden with data storage and solar-powered radio transmitters towards every star we can see.

If we ever manage to colonize other worlds, then over a few millenia there will be an exponential population growth, and nary a corner of the galaxy will be free of us.

But evidently, this hasn't happened yet. Where are all the alien visitors?

Again, using ourselves as an example, the most likely possibility is that whenever technology increases to the point where a species can venture into space, it also allows the species to destroy the viability of it's entire ecosystem. Looking around at the relative popularity of military activities vice space exploration, which one do you think will happen first?

Darwinian evolution dooms us- it creates a locally optimal species, which struggles violently against its peers for resources, always knowing there is a frontier to explore where more open land can be found. But when the frontiers are gone, and the planet is full, it leaves us with a competitive psychology that will be unlikely to abide cooperation long enough for us to "get off the rock".

Look at the science-fiction worlds of something like Clarke's 2001. Flight to Jupiter in 1997? It seemed reasonable then- because it was on the assumption that petty nationalist squabbles wouldn't divert our attention and resources in the meantime. Sadly, that is exactly what's been happening.

How can Freeman Dyson complain about a technical problem in Prey when his famous Dyson Sphere ( a star surrounded by a shell with ppl living on the inside ) is flawed as well.

Because he didn't:

The original proposal simply assumed there would be enough solar collectors around the star to absorb the starlight, not that they would form a continuous shell. Rather, the shell would consist of independently orbiting structures, around a million kilometres thick and containing more than 1e5 objects. But various science fiction authors seem to have misinterpreted the concept to mean a solid shell enclosing the star, usually having an inhabitable surface on the inside, and this idea was so compelling that it has been the main use of the term in science fiction. The earliest appearance of this version seems to be Robert Silverberg's novel Across a Billion Years.

Freeman Dyson postulated the idea of a Dyson Sphere, which is basically a planet that was built as a shell surrounding a sun, using all the energy it radiates.

Also mentioned in the TNG episode Relics.

Level 1 - Capture and harness the energy of the atom. We have NOT done this. Nuclear fission is a bastardization of the true possibilities of the atom. Until we succeed in harnessing nuclear fusion into a viable energy source, we wont reach level 1.

Level 2 - Harness the energy of a star. Ie. A Dyson Sphere. We're probably a couple hundred thousand years away from this - if we dont blow our selves away before then.

Level 3 - Harness the energy of a galaxy. I cant even come up with a direct comparison to pit this against - except perhaps an indirect one. If anyone has read
Carl Sagan's Contact (excellent read - the book not the movie) - there it is suggested that a co-operative project between galaxies is *making* Cygnus A - to the end of increasing local matter density to prevent the universe's expansion in that area. Cygnus A is the second loudest radio source in earth's sky -- and its 600 million light years away. Talk about large-scale engineering.

Sort of offtopic, but food for thought.

It will all melt in a pile of goo.

The lion approached the wolf and the fox, and suggested that they form a partnership for the purpose of hunting game. The lion explained that each had particular talents that would lend themselves to such a partnership. The fox was wily and could trick the quarry into the open; and the wolf was swift of foot, so that he could direct the quarry to where the lion lay in wait to complete the kill. After some discussion, the wolf and the fox agreed to enter into a partnership with the lion. All went as planned and a deer was killed, but when the wolf and the fox tried to share in the kill, the lion challenged them. They stood by, helplessly, and watched the lion devour the entire carcass. Afterward, they asked the lion why he had only left them a few scraps. The lion replied, "All I took was the lion's share."

* MIDI workstation: logic audio | cubase | or even (puke) cakewalk

I've heard that MusE and Rosegarden are pretty decent, though I haven't really used either.

* Powerful trackers: buzz | FT2 | IT

Have you tried SoundTracker? I don't know much about tracking so I wasn't able to evaluate how good it is.

* Advanced outboard softsynths: reaktor | absynth | Q1 | grainlab

What about Spiral Synth Modular?

* Powerful sample editing tools: cool edit/96/pro | soundforge

I think Audacity is pretty capable. There's also WaveSurfer, and Sweep.

Btw, I'd be glad to be wrong, if someone would only point out the links to *stable* and *feature-filled* tools.

Perhaps you are wondering what an NP-complete problem is or what this P vs. NP stuff is all about. You might want to check out the comp.theory FAQ and scroll down to 7. P vs NP. It gives a bit of history and a decent description.

Or check out The P versus NP Problem at Clay for a really good description (unfortunately too long to quote here). And lastly, you might want to check out Tutorial: Does P = NP? at VB Helper for a little more info.

Ok, but what is it good for? The Compendium of NP Optimization Problems is a great place to look for real world examples of NP problems. Including everything from flower shop scheduling [nada.kth.se] to multiprocessor scheduling.

Hopefully that helps. I was very clueless when it came to P vs. NP stuff that always seems to be mentioned on Slashdot. So I took the time to look it up. Now I'm clueless but I have links to share. :)

Human feces can carry an enormous number of very evil microorganisms. Tempting as it is, and as much as this guy may deserve it, you need to also think about the health risk to innocent employees of FedEx or UPS or the Post Office. Do not ship human feces. (See reference.) Urine is relatively free of pathogens, and easy to ship safely.

"I believe the technique the parent described is a form of hash sort."

You'll find more techniques like this in the literature if you look for integer sorting.

>This isn't in O(N) unless your mapping meets certain criteria.

Er, oh yes it is. If the memory I'm writing to is the lights in the scoreboard at Yankee stadium - or directly into video memory - why on earth would I need to collect the results? Collection is not actually part of the sorting problem.

Anyway, I did say:
* that it was absurd
* that its /practical/ if you have /no duplicates/ and you /fill a range/ with the keys (ie NO GAPS).

Its not bounded by O(N ln N) because it doesn't use comparisons between keys.

Read e.g. this paper which mentions this /and other/ algorithms that beat that bound, because they don't use comparisons.

BTW, if you are the same Tom7 who makes the fonts, I bow humbly before you - they are brilliant :)

-Baz

PS as for the Anon comment on storage in memory taking O(ln N), this is true of quicksort as well, but is ignored - complexities for in-place sorts assume that memory access is instant. If you do take that into account you'll find quicksort has an O(N ln N ln N) term but the constant in front of it is tiny, and in practice the assumption of instant memory - on which the quicksort bound is based - is true. Consider that even if the N ln N term was just 100 times larger than the N ln N ln N term you'd need of the order of 2^100 items to sort before it dominated!

This page has a matching description, but I think this is what you were looking for.

I'm was pulling down a whoppering 1.0kb/sec from ftp.mozilla.org, thanks to slashdot linking directly to the master server. PLEASE use a mirror, there's a full list of them here. Not all mirrors carry phoenix, and some that do don't have 0.3, but at least this one does (and probably others too).

Well, Freeman Dyson is that Dyson.

Just an OT on your sig: I was at 42 when they changed it from numerical to something silly. Almost got to the cap. Wonder if there still is one?

Back on topic: solar-cell covered Earth is the future. It's the first step toward solar preservation. The next step is a Dyson sphere , a shell around the sun with solar panels on the inside and batteries on the outside. It'll save as much as it can, and when the sun's due to explode it'll separate and move the pieces out of blast range, to be reused once things settle down.

The goal is to help make the universe last longer, by delaying entropy.

I have written a small tcl script (called pkgusage) that lists all your installed packages (RPMs or DEBs) together with the number of days ago you last accessed any of the files in each package. Thus, if you do "pkgusage.tcl | sort -n", packages which you seldom / never use will be at the end of the list.

It also checks dependencies between packages, so it won't tell you to uninstall a package that something else depends on.

I would be impressed with a Dyson Sphere out of legos. That would be cool.
And you could have a little Scotty Lego charachter next to a crashed shuttle craft on the surface.

Factoring, AFAIK, is not NP-Complete. Traveling salesman is. Here's a list of known NP-Complete problems, if you're interested.

Use AFS and kerberos. Works for mit.edu, Ericsson, kth.se and MANY others so it should work for you too.

http://www.openafs.org

dysons-sphere

I agree with everything you complain about with the exception of the Dynsons-Sphere. While this is something we can't build with todays tech it is conceivable for a society more advanced then ours. And yes I know it would probably not look exactly like the one in the movie, but it is by no means an impossible object (like the transporter or time travel)

Virtually all the energy stored in any form usable by people ultimately comes from our sun. Strangely, outside of bizare projects like a Dyson Sphere, and solar panel research, there seems to be very little interest in getting more power directly from our sun.

Regardless of all that, any energy that we manage to collect may be relatively efficiently and conveniently stored using hydrogen. We may synthesise hydrogen from water, and may use it in a variety of reactions before and after it is used for energy. Hydrogen is of course, very versatile.

Yes, it's all theoretical, having reached only the beginnings of proof-of-concept in this application - but to look into the possibilities would hardly be a waste.

:^)

No need for new projects -- already good distributed filesystems that you can set up big servers with
afs? (or here)
coda?
intermezzo?

CMU, for example, uses AFS campus-wide. Your login scripts and dotfiles and whatnot all reside in your home directory (on AFS) so preferences migrate with you.

You can make things world-readable, and because AFS has a global namespace, anyone can see them. If I do research at MIT as well, I just need to grab a Kerberos ticket from their KDC and start using my files over there.

Just plonk a server in place, put an array of 100GB drives in place, make things readable by whomever you want, and you're good to go.

If you want a system designed with fancy automated caching that people can use without dicking around with Kerberos, freenet's a good choice. Of course, there's no guarantee that the data will stay around, but cest la vie.

It can be used to authenticate logins on Windows 2000 (and probably XP), Unix (use PAM on Linux, Solaris etc., SIA on Tru64 and hack the XDM on others).

Use it to authenticate telnet and ssh logins. There are clients for MacOS, Windows, and Unix. Use it for authenticated X11 forwarding. Use it for FTP. Use it for POP3 and IMAP4 with Kerberos authentication or SSL-encrypted passwords (cyrus-imapd). Use it for AFS to replace the insecure NFS and to allow your users to access their home directory from home. Clients exist for most Unix variants (including MacOS X) and Windows 95/98/2000/XP.

Kerberos has single sign-on.

Why Kerberos instead of LDAP? Because Kerberos is an authentication scheme, not a password database.
