HFS+ uses B-trees and actually stores all files in all directories on a volume in a single database (two files). To move a file or directory to a new directory, you just change its parent node ID in the data structures. The file name is used as a key and so HFS+ directories are inherently sorted by name. You can iterate up to the root from a file/directory (create a full path to it) by looking at its parent ID, then stat-ing that, etc. until you reach node 2 (the root).
UFS2 uses the standard UNIX inode system where files are stores in inodes and directories are basically lists of inodes. The files (inodes) in a directory are stores in the directory itself and thus to move an item to a new directory you have to remove it from one directory structure and put it in another. The items in a directory are stored in apparently random order, new items go at the end for convenience sake. If you want to view a directory in order, you have to iterate it and then sort it. Inodes don't have parents, if you want to create the full path to something you only have the inode number for, you have to start from the root and search down through every directory until you fine one that has the item with the same inode number as the one you were looking for. Now you've found the parent of the item you had. Now repeat this process (searching every directory on the entire disk) until you find the parent of the new item you just found. Continue this process until you find your item in the root directory. Obviously it may be possible to cache somewhat to streamline this, but you'll likely end up searching the entire volume at least once. Because of this, full paths are the only realistic way to keep track of UFS (UNIX) files, whereas Macs once had FSSpecs and FSRefs which only used volume identifier, parent directory ID and filename.
I updated Firefox, it said "you better update Flash", and so I went to update Flash and Adobe tried to insert a new plugin into my browser!
This seems like a poor bargain to me. Firefox pushes us to the Adobe site so we can update our buggy Adobe add on to be less insecure and Adobe takes the opportunity to put another add on in, which probably has its own bugs.
Anyway, I clicked no to that offer to install Adobe DLM, and somehow managed to install the new Flash anyway.
It uses more power, but if it gets the job done more quickly, it could still use less energy. Much like any current computer will get a sizable job done using less power than an Apple ][, even though the power supply and power draws are much bigger on the modern PC.
Also, the article tries to compare the laptops and gives system performance in minutes/mAh. But the article doesn't give the voltage of the battery packs. What is the minutes/mWh?
I agree the US was unlikely to get the Olympics. With the previous Olympics being in London, Chicago was way down the list. Go from one predominantly white, English-speaking country to another?
The Olympic committee has shown interest in taking the Olympics to a broader range of cities as of late, Chicago just wasn't in the cards.
I also thing it's interesting people have forgotten so quickly the bribery scandals in regard to Olympics selection just a decade ago. Even if there is no out and out bribery, with a prize as valuable as the Olympics in the hands of a relatively small number of people, there will be massive levels of plying, cajoling and favor-currying. The impact of this on the selection process has to be at least as large as that of the border policies of the countries involved.
This is very standard for border checkpoints. We used to travel back and forth to Canada in the 70s and this would happen from time to time in both directions. It's just like some guy searching your luggage when getting off an airplane, which happens everywhere from time to time too.
It there to deter smuggling.
As to things changing since 1996, perhaps you didn't notice the US has had the Olympics since then? Since 9/11 even.
'Because Snow Leopard lacks fully-functional ASLR, Macs are still easier to compromise than Windows Vista systems, Miller said. "Snow Leopard's more secure than Leopard, but it's not as secure as Vista or Windows 7," he said. "When Apple has both [in place], that's when I'll stop complaining about Apple's security."'
Oh yeah? Is that a promise? I more expect he'll stop complaining when he stops making money by complaining.
The final letters in an electronics part name are almost always a package code. Especially in this case, where UBG could easily stand for Micro Ball Grid (u being a mu), meaning a micro (high pitch) ball grid array package.
I think this article is really dumb. Almost certainly the new Touch doesn't do n at all. Just because the chip can do it, doesn't mean Apple loaded on the software that does it. And why should they if it only has a 2.4GHz antenna?
On this same front, if Apple didn't put in an FM antenna, it isn't going to be receiving or transmitting FM either, even if someone does manage to smack the software into there somehow.
My house has one but it doesn't work. It just hums. I opened it up to find out what was wrong and it's chock full of vacuum tubes. So I gave up on it. As I redo rooms, I remove the panels and cover them up. But no one likes a hole in their wall, so some still remain for now.
Violence is violence. It doesn't have to be against a person to be violence. Unless you think they carefully disassembled these towers, you're wrong that this isn't violence. And when they burnt down buildings at Vail, that was violence too.
Yes, I want to lock these people up. It has nothing to do with whether the US has other problems right now. And making up a freerolling strawman argument to condemn what others want to do isn't helpful either.
Come on, fixing the Pandora problem was as easy as changing the firmware that listened to the battery.
It is an enormous stretch to think that the PSP Go! doesn't have a removable battery because of the Pandora battery. Wouldn't you think it would be more because non-removable batteries are in vogue in high-line devices like the iPod Touch and Zune HD, both of which the PSP Go! competes with?
This wrap-up article appears to be a Palm piece designed to attach them more firmly to Apple in people's minds. Trying to imply Palm is so great that Apple is trying to stop them and also imply that Palm is just like Apple, in fact they have half of Apple's engineers!
The real kicker is the last part. "These people work for Rubenstein". Yeah, maybe that's true for Mike Bell. Pete Alexander (who used to work for Mike Bell) just quit Apple (was forced out) and will be working at Palm within 3 months.
But there are a lot of people for whom this doesn't apply. I used to work for Rubenstein and I can tell you he's so much not a people person it's ridiculous. He makes 2000-era Al Gore look personable. He would periodically get up and address the team and he would say things that clearly showed he didn't any real connection to us or even know what we were doing. For example, he once rallied us by saying the software/hardware release we just did was the best one we had ever done. The whole crowd groaned because we knew it wasn't, that it was pushed out the door and in fact we had a plans for a near-term emergency.0.1 update and a rapidly following.0.2 update.
Maybe if you work directly for the guy day-to-day you can form an attachment to him, but to anyone lower down in the ranks, it isn't the same.
As to why Steve Jobs "let" Rubenstein leave, I'm sure it was similar reasons as why Tony Fadell left. Because both realized they wouldn't be the next CEO of the company. Steve Jobs only action then of "letting" them leave was to not step aside and let Rubenstein or Fadell be CEO. Rubenstein got out, and lo and behold he's now the CEO of Palm.
There's one more difference. One system of measure has a group of people so convinced it's the best thing ever that they think the law should prohibit people from using any other.
If the metric system is so great, why is it necessary to try to force people to use it? Let people use whatever measuring system they find most useful and if the metric system is better, it'll become dominant.
What is with the hostility toward this movie? It strains credulity in certain parts, but so what? It is no less absurd than The Matrix, or Blade Runner, or Aliens, or Terminator 2, or Firefly, or Babylon 5, or... have I slaughtered your sacred cow yet? This is one of the best science fiction movies of all time. Whine all you want, that consensus is already forming, and there isn't a damn thing you can do to stop it.
What hostility? I have to harbor hostility because I don't think the movie is a good sci-fi movie? That's such an absurd statement, it seems to show a mindset that people aren't making up their own minds, they're just being nasty. Then you go on to act like I need to submit because other people think it's a great sci-fi movie. I assure you this isn't true either. I'm entitled to my own opinion, and it doesn't have to agree with yours to be right or for me to hold it.
Absurdity has nothing to do with it. It's not that it's off-kilter, it's that it's not a sci-fi story.
It's hilarious that you list Aliens and Terminator 2 as my potential sci-fi sacred cow. Seriously, if a person says District 9 isn't a sci-fi movie, is he likely to consider Aliens one?
It is far from unprecedented. Visually, it follows in the footsteps of Cloverfield, with the way the cameras are used and are supposed to be "documentary-style" (although shaky as hell).
The idea that the CGI in this is unprecedented is ridiculous. First of all, Vetra Vaal came out years ago and you could intercut it with this movie (both were even shot in shanty towns around Joburg) and barely be able to tell them apart.
You can't tell me what I can't dismiss. You especially can't tell me I can't dismiss a movie which turns into fire fights with a ridiculously over the top "don't make me do all this for nothing" scene interspersed. And especially don't go telling someone else their opinion isn't valid because they haven't seen it. Seeing movies isn't free, so people have to make their buying decisions based upon things other than actually viewing the movie.
I was disappointed in the movie. It was hyped as being sci-fi, including a parable about apartheid. The parable is barely touched upon, and the movie never recovers from running out of story 1/3rd of the way in. A movie that started off so interestingly, and so subtly did things like explain the name for the aliens (the word "prawn" is first mentioned in an interview with a man on the street) instead turns into a huge firefight combined with hamfisted emotional outbursts about the quality of those in "Gears of War". Frankly, the whole thing almost turns into "Gears of War", as a friend pointed out, it feels like a shooter (including the cameras on the guns) and it even is all brown, like a next-gen shooter.
It's a buddy cop film (witness the parting scene) and a shoot-em-up. It barely even delivers on the apartheid parable before jumping with both feet into bloody firefights.
This article makes a few factual errors. But that doesn't mean that the criticism of this revolutionary process of making a plane is unfounded. Many suppliers have had problems and Boeing even had to buy one out to ensure they could supply parts. The plan looks like a disaster right now, although it may be too early to sell. In theory it all could turn to roses tomorrow and stay that way for a 10 year run. But with all current evidence, the plan looks like a mistake.
The problems are with barrels that aren't even close to production yet. Boeing (in as much as you can believe them anymore) says that this will not delay the production of the 787 (to first flight) of the 787 any further than it already has been.
This information is out there, is it so difficult to go find it before publishing wrong info instead?
Oh yeah, and the problem with the sections isn't with the skin, it's with the stringers behind them. It leads to wrinkles in the skin, but the real fix is to not mess up the stringers in the first place.
The statement that this casts even more doubt on the outsourcing model set up at Boeing under Alan Mullaly is most definitely not diminished by the inaccuracies in the reporting of these details.
Simultaneously wanting to flout society's norms and then pretending you don't. Because, as you see, the behavior hasn't changed from a few years back, it's the recording of it that has.
If you could lose your job over what you do at Burning Man (and I really hope this isn't the case), then perhaps you should stop and consider which is more important to you, your job or doing this behavior. And then once you make your decision, live with the consequences instead of trying to blame someone else for your behavior.
I think it's great you want to be friends with people who are unlike you. But I don't agree with your decision that a great way to do so is to deceive them about how you are. It's this kind of thing that allows bigots to say "well, all my friends are decent people and that's because none of them are (gay|perverts|Democrats)".
TiVo didn't misappropriate the Linux kernel. If TiVo had misappropriated the Linux kernel, they would have been sued by the FSF.
I do feel somewhat sympathetic about the problems of putting on Burning Man. But saying it us the US legal system or cultural systems that cause this problem is ridiculous. The problem is that technology is making what people thought was once private behavior more public. And they then are worried about or ashamed of others finding out what they did. This isn't a legal system problem. This isn't a cultural system problem. It's individuals somehow deciding it is important to them to appear to be conforming to the morals of others but to not actually do so!
Slashdot Mirror
file `which gcc` /usr/bin/gcc: Mach-O universal binary with 3 architectures /usr/bin/gcc (for architecture i386): Mach-O executable i386 /usr/bin/gcc (for architecture ppc7400): Mach-O executable ppc /usr/bin/gcc (for architecture x86_64): Mach-O 64-bit executable x86_64
And I wouldn't be shocked to see Apple package ARM Mach-Os into some files soon too, with this pseudo-netbook thing rumored.
HFS+ uses B-trees and actually stores all files in all directories on a volume in a single database (two files). To move a file or directory to a new directory, you just change its parent node ID in the data structures. The file name is used as a key and so HFS+ directories are inherently sorted by name. You can iterate up to the root from a file/directory (create a full path to it) by looking at its parent ID, then stat-ing that, etc. until you reach node 2 (the root).
UFS2 uses the standard UNIX inode system where files are stores in inodes and directories are basically lists of inodes. The files (inodes) in a directory are stores in the directory itself and thus to move an item to a new directory you have to remove it from one directory structure and put it in another.

So in short, they're not at all alike.

Why didn't you just wait for the warranty to expire and then pay the $130 instead of $180? Or say it's grey market it has no warranty?
I dunno, they seem fully misunderstood in this case.

Top Gear tries to stay away from useful facts and info as much as possible.
And the idea of Top Gear having TWO cars that cost below $40,000 on the screen at the same is pretty far fetched.
