That's interesting. I'm on a solaris system at the moment so I can't do this myself, but you can run objdump -h on the linux binary, and look for the VMA , which is the virtual load address for the binary. This probably gets set to some typical value, looks like ~128MB on linux, so the lowest 128MB is unmapped, which seems a little excessive (the lowest pages should definitely be unmapped as a trap for common pointer errors), but I don't know where linux typically loads its shared libraries. If you want to play with this, you can try generating the asm for some test program and inserting an org directive in there, where address could be say 4096!

If you're curious about the "0xfeedface" in the header for mach_kernel, it's the MH_MAGIC constant present in every Mach-O executable (part of the struct mach_header that also contains things like the cpu type the executable is intended for). That constant is very cleverly called MH_CIGAM on machines with a little-endian byte order:-) See here for details.
I've commented on Jackson's movies here before, and one such comment is here here I had a couple of others, but it looks like it's impossible to search for my older comments by username alone (my slashdot homepage shows my last 24 comments, is there a way to get at the older ones?).
To summarize, I loved the cinematography, the costumes and rendered monsters such as the Balrog and gollum, but not much else. The spoken elvish was pleasant, and I was in awe of the statues of the kings by the Anduin. I had several problems with the bridge scene in moria, see the linked comment.
Samwise and Gandalf were pretty well portrayed but Frodo was quite awful; long, lingering shots of vacant expressions on his face detracted from the movie greatly. The Frodo in the books had an innate nobility which the movie Frodo never shows a glimpse of; he has no leadership abilities, and looks like he took acting lessons from a rabbit.
Galadriel suffered from a severe case of radiation poisoning for some reason, marring an otherwise good performance from the lovely Cate Blanchett. I don't disagree with the decision to excise Tom Bombadil and the barrow downs from the movie, but having Aragorn dole out daggers of Westernesse from a sack was ludicrous (should've come up with a short and reasonable alternate expression..these daggers were heirlooms from Numenor or something like that), as was the B-movie grade "duel" between Saruman and Gandalf.
Gimli is apparently transformed into a walking joke in the second movie, which I haven't seen. Boromir was skillfully portrayed - hats off to the actor.
The 5 minute "drowning" scene at the end of the first movie was painfully boring and served no purpose whatsoever; it could've been put to much better use.
I'm not surprised that the Tolkien estate detests Jackson's work (I think they're merely okay movies, which could've been a lot better), and doesn't want to release the rights to "The Hobbit". I'm glad the movies were made, since I'm sure it will bring many new readers to the books, but they could've been immensely better.
This seems one of the more insightful comments I've yet seen on the issue, by someone who is presumably in a position to know. When asked about why artists feel that they don't get a significant percentage of the revenues from their CD sales, Jobs said:
The winners pay. The winners pay for the losers, and the winners are not seeing rewards commensurate with their success. And they get upset. So what's the remedy? The remedy is to stop paying advances. The remedy is to go to a gross-revenues deal and tell an artist, "We'll give you twenty cents on every dollar we get, but we're not gonna give you an advance. The accounting will be simple: We're gonna pay you not on profits -- we're gonna pay you off revenues. It's very simple: The more successful you are, the more you'll earn. But if you're not successful, you will not earn a dime. We'll go ahead and risk some marketing money on you. But if you're not successful, you'll make no money. If you are, you'll make a lot more money." That's the way out. That's the way the rest of the world works.
So you see the recording industry moving in that direction?
No. I said I think that's the remedy. Whether the patient will swallow the medicine is another question.
How feasible is this? Are production costs reasonable enough that creating a record without an advance is possible?
gwernol knows what he's talking about. Quicktime does indeed have a relatively self-contained (and ancient) mac os-like services layer that has been ported to windows as well, and I believe iTunes for windows uses those APIs (which is why it's so bloated). Most developers arriving or porting from other platforms (or indeed, from OS 9) are far more familiar with C++ than with Objective-C (which, while quite a useful language, certainly has its own share of performance problems - dynamic binding and typing don't come cheap, and function call costs are relatively high, for instance), and tend to use Carbon, even though it was originally intended as a compatibility layer. However, if you stick to one programming model (Cocoa and ObjC, for instance) programming for OS X is much easier than doing say MFC for windows.
A quick google search yielded nothing pertinent about limestone in zaire and the K-T extinction - any pointers? I'm no geologist, by the way. The primary evidence for the Alvarez theory of extinction caused by asteroid impact is the abnormally high concentration of iridium and other siderophiles in the K-T layer, since iridium is present in abundance in chondritic meteors. The presence of tektites and shocked quartz also ties in well with this theory.
It has been theorized that an asteroid impact was responsible for the "K-T extinction", when the dinosaurs vanished en masse. In that light, cutting funding for asteroid tracking programs is more than a little shortsighted.
I'd agree with that comment if you substituted "Tolkien geeks" with "geeks". Unless you're a member of the Tolkien Society or the like, I don't see how you can claim to speak for the Tolkien geek collective:-)
I liked Jackson's "Fellowship" for its stunning sets and cinematography, but not very much else. However, if it encourages viewers to discover the books for themselves, that's a great positive. Some of the deviations from the narrative of the book are understandable, but most are not. Even foregoing the issue of changes from the text, which have been discussed elsewhere, there were some glaring negatives (in no particular order):
. The balrog of Moria was realized wonderfully, but the end of the bridge scene was a complete disaster. In the book, Aragorn and Boromir stand behind Gandalf and face down the balrog on the bridge, while the rest of the company waits inside the doorway at the end. In the movie, all of them huddle inside the doorway, while Gandalf stands alone on the bridge. In the movie, when the balrog pulls Gandalf down with it, Aragorn (for whatever reason) has all of a minute or two to run over and pull Gandalf up (the way it's filmed..to add to the "tension", presumably) - instead, he restrains Frodo (which is okay, as he has to be protected, but the way it's filmed, it looks like Aragorn has ample opportunity to run over to Gandalf, instead he's portrayed as a coward).
Over the bridge!' cried Gandalf, recalling his strength. 'Fly! This is a foe beyond any of you. I must hold the narrow way. Fly! ' Aragorn and Boromir did not heed the command, but still held their ground, side by side, behind Gandalf at the far end of the bridge. The others halted just within the doorway at the hall's end, and turned, unable to leave their leader to face the enemy alone.
. The long, lingering shots of the vacant expressions on the actors faces (notably Frodo; Gandalf was excellent, and Sam was pretty good too), and the five minute "drowning" scene towards the end could've been replaced with a real scene, such as an explanation of how Aragorn could dole out daggers of Westernesse from a sack.
. Why was Galadriel depicted as suffering from a severe case of radiation poisoning? Cate Blanchett is a great actress, but the director's vision of Galadriel was flawed. All of this is IMO of course, but there are many who agree with me.
Anyway, flame on.
Actually, I'm surprised this isn't the de facto standard, at least in the commercial linux desktop distributions, since startup time is a reasonable thing to optimize for desktop machines (a journaled filesystem certainly helps:-). Mac OS X has a parallelized service startup sequence as well, and a dependency grouping technique - see this paper for some information.
Vinge's fiction is quite wonderful - I think I've read nearly all of his work, and I rate everything besides the "peace war" novels as excellent. The "peace war" novels were merely good. That said, the setting does tend to overshadow characterization in "A fire upon the deep" and a "Deepness in the sky". Not so with most of his short stories - I highly recommend "True Names", which was quite probably the first story to introduce the concept of cyberspace (4-5 years before "Neuromancer" - and while I liked Neuromancer, "True Names" is a vastly more important and interesting work). You could also read "The Blabber", which is set in the universe of "A fire upon the deep", but doesn't switch perspectives, and at heart is really a story about a boy and his dog-like alien:-)
I started PS:T a few months ago, and while I thought its morbidity and general eerieness were interesting, I stopped playing just before my character was about to leave the dustmen's mortuary. I do have a saved game at that point:-) What did you find most exciting about the game? I solved a couple of puzzles, but there was one puzzle whose solution made no sense (the folding paper thing). There was no real combat (and it wasn't necessary either), so I guess the quest for identity of the nameless one should've captivated me. Ah well - I looked up the d&d planescape stuff, and it seemed quite incoherent in the sense that it was basically a melange of a great many different mythologies, half-formed settings and so on. Thoughts?
This could be because the TCP stack on your OS doesn't implement ACK prioritization, which can be pretty useful on links with asymmetric bandwidth limits, like DSL. Essentially, when you max out your upload bandwidth, you also increase the amount of contention/latency experienced when sending the TCP ACKs which need to be sent in response to the TCP packets you download (to let the sender know you've received them, since otherwise the server has no means of knowing if they actually got through to you, rather than having been dropped along the way). This in turn could lead to retransmits/rate throttling by the server sending you the matrix (or whatever), thus causing slower downloads. Of course, part of this may also be due to some other factors, such as a broken algorithm in bittorrens. Here's a good link to learn more about this: ALTQ
Interesting. I'd also like to note that LaTeX, the Knuth/Lamport typesetting system available on a great many platforms (including Windows), has had an elvish font for several years. I am no elvish scholar of course, so I can't comment on the appeal of the LaTeX approach to the elvish cognoscenti:-)

The One Ring:
{\elvish
Three rings for the elven kings under the sky
Nine for mortal men doomed to die
Seven for the dwarf lords in their halls of stone
One for the dark lord on his dark throne
In the land of Mordor where the shadows lie
One ring to rule them all, one ring to find them
One ring to bring them all and in the darkness bind them
In the land of Mordor where the shadows lie.}
I've read "The da Vinci code", and while it was superficially entertaining, almost every topic the book touched upon had a factual error, including the geography of Paris, some details about Leonardo's paintings, and several others. The subject matter (conspiracy theories involving the Holy Grail) is very exciting though, and a blitz marketing campaign made it a success. If you liked the subject, but prefer to get your facts straight, I recommend a novel by Umberto Eco (author of "The Name of the Rose", which was made into a movie starring Connery), called "Foucault's Pendulum". It's a hefty tome, but worth the read.
metaserver.us.netrek.org worked as of a few days ago. The syntax, as I recall, was
netrek -m metaserver.us.netrek.org
(for the COW client at any rate). There aren't nearly as many players as there used to be a few years ago (I played for a while just after starting college).
I agree with you about Voyager (I gave up after seeing a few random supposedly "good" episodes), but it's quite clear you never really watched DS9. It had some of the best Trek episodes ever ("The Visitor", "Far beyond the stars", "hard time" etc.), and was quite engrossing because it abandoned the "restore to status quo at the end of each episode" formula. IMO, the best of DS9 was on par with or better than almost all of TNG (which I liked most of the time - "The inner light" was perhaps the best Trek episode ever, along with "the visitor").
I saw a couple of episodes of Enterprise from the first season ("dear doctor" because it was recommended by a friend, and I thought it was awful and amoral), and I honestly have no idea what the creators of that show are trying to do. Nemesis was utterly banal and plot-free, and it wasn't even consistent with what we saw in TNG. Unless there's a new show, preferably set perhaps another 200 years in the future of TNG/DS9, with someone like Leonard Nimoy at the helm, I think we've seen the end of Trek.

Oh, there are plenty of funny program names. Perhaps one of the funniest examples is on Mac OS X, where the apple gcc gives you the option of generating "fat" binaries, which are combined ppc and x86 executables (so you can run them both on x86-darwin and ppc for instance). The tool to create a single architecture "thin" binary is called "lipo" (as in liposuction..). I had a good laugh when I saw that.
