That's it. Everything else is derived, e.g N is kg*m/s^2, Pascal (Pa) is N/m^2 and J is obviously N*m or W*s ot kg*m^2/s^2.
The Water/weight/volume thingie is not part of SI (since 1889), it's just handy and was part of the original standard, but nowadays the kilogramm is defined as the mass of the international kilogram prototype, which happens to be the only SI base unit that is not derived from a fundamental constant, and really ought to be replaced.
One of the tricks is to get the proper distortion at the edges by rotating the camera about the correct axis or point, and not about the standard tripod mount. The right point is ususally somewhere inside the lens, or at the front of it. Also, the proper software like Panorama Tools help matching the overlap properly.
Considering exposure, you may have to take manual control over this instead of letting the camera choose for every image.
Mozilla is coming back in a big way. Fast, clean, lots of new features (I'm not going to call it fresh), and lots of choice.
come on, you know that one better. Mozilla is not fast. Everything except deeply nested tables is much faster in netscape 4.x. (Yes, I know, 4.x isn't standard compliant by any stretch of the definition and crashes a lot, but it's still way faster than Mozilla).
Mozilla isn't very clean as well. Gecko may be, and maybe Firesomething as well, but Mozilla isn't. It has some very annoying UI bugs since at least 1.2 (i.e. keyboard input gets processed by the wrong window, e.g. closing tabs in some window on a different desktop when pressing Ctrl+w, or even going into some other URL-bar when you hit Ctrl+L. the worst one however is that Mozilla even manages to load bookmarks you selected in different windows than the one where you opened the menu. Before you ask, this is independant of OS and window manager). And what was that multithreading thing that's supposed to be better than in Netscape 4.x? Mozilla still blocks all instances when rendering certain complex pages.
Yes, Mozilla definitively has soul, it does far too often what it wants, instead of what I want. Sadly, there's nothing better in sight, except perhaps Firebird. And Mozilla is definitively better than IE, which doesn't even pretend to allow me to do what I want, but it still isn't good.
There has been an article on this in Stereophile, which is usually considered an audio industry shill. This has been discussed widely in various newsgroups and fora for some time before this article was published.
To my understanding, Dolby just "accidentially" works on audio CDs, while DTS CDs are part of the DTS definition. There are only very few DTS CDs available, but I only know of one source of Dolby Digital for CDs, and that's a download from the swedish radio, but only two of the ten downloads are available in DD as well, the rest is DTS only.
The remastered Dark Side of the Moon DSD is incredible... and it's the perfect example of a SACD with a different mix on the CD layer. So if you're comparing the CD and DSD layers of this CD: they have intentionally been messed with so that you come to the conclusion that DSD is better.
BTW, how do you know how it sounds 'like you are in the studio'? Are you sure this is not the result of a little re-equalization, noise-reduction, filtering and whatever?
If you ask me, the next big thing in terms of sound improvement is not any of those high resolution media, but room correction. Nothing short of rebuilding your listening room will give a comparable improvement in accuracy of reproduction.
DVD-A and SACD media and players are available since a number of years, the DVD-A specification is from 1999, and sony's first SACD player was introduced in the same year. Players that support both formats are available since more than a year. Neither format has caught on for a number of reasons, the higher price of players that support any of them beeing the most important imho, but there's also the lack of interesting content and that people don't want to end up with media in a format that could die out in a few years.
On the topic of SACD, SACD2 is currently beeing discussed, so SACD is definitively old news.
2056 UTC is when it's actually happening. We'll have to wait another 80 minutes till Cassini's radio signals sent during the flyby reach earth. Nothing here to see until at least 2220 UTC.
Personally I find it very rude to send me Short Messages that require an answer. Not only does it costs me money to answer someone elses questions, but it also find it awkward and annoying to type them.
If I don't have the time to talk to people, I either wait until the ringing (vibration only) stops, meaning that they have either given up (can not have been important then) or get to talk to my voice mail box, or I just hang up on them.
I actually read the manual to decide wether or not to buy one. Since when is trying to make an informed decision geeky? I'd say, considering the price of this thing, anything else is just plain supid.
This is not true. I've discussed the mobility limitations of the old trilobite with the german support people of electrolux, and they very clearly stated that the trilobite can not replace a conventional vacuum cleaner, although this was not at all part of my original question. They also forwarded me a PDF of the manual, which I found rather interesting. All the marketing materials for the Trilobite that I have read so far define it as just the same as you describe the roomba - an addition to a conventional vacuum cleaner, just without the "inexpensive". Personally I'd say the higher price, which closer to 5 times the price of the roomba - trilobites are sold foer EUR 995 around here (with sales tax and the current exchange rate that's about the same in US$), is well worth what you get. If you want an even higher degree of autonomy, there's the Kärcher robocleaner, which can also empty its dust container at the base station. However, it is more of an automated brush with even less sucking power than the roomba.
the Titan probe may possibly land in it and float for a few hours.
It may float for an eternity, but its batteries will run out only a few (possibly ony three, depending on how long the trip through the atmosphere lasts) minutes after the impact/splashdown. See the mission timeline on the esa webpage.
Maybe you should invest in a closet, probably something with drawers (and actually use it!) before forking over 2 grand for a vacuum cleaner. But seriously, the manual for the old, red trilobite explicitly warned the user not to leave stuff they had rather not sucked up on the ground.
That one's easy: The reviewer's broad definition of "Operating System" is Microsoft's fault. If they hadn't been insisting that IE is an inseperable part of Windows, the reviewer would never have called the software on this box "awkward linux-based operating system" when he was actually complaining about the user interface.
That's where the original posters "treble damages" come from. He ment "triple damages", which is what IBM can sue for if you knowingly violated the patent, as opposed to just the damages.
With Cellphones Europe seems to be ahead of the the game compaired the US.
And that's why the GEMA, the german equivalent of the RIAA has been charging for ringtones since almost 3 years - and that's for barely recognizable monophonic stuff, not those fancy.mp3s of.wavs.
History of Computing Hardware mentions the Zuse Z3, which was binary, program controlled and despite the fact that it didn't implement conditional branches, turing complete. The wikipedia articles on Colossus don't mention when that was built, so I guess that was after the Z3 in 1941. I wouldn't count ENIAC, since it was decimal instead of binary, and had to be rewired to run a different program.
While it is true that modern filesystems are much less affected by fragmentation, both in the amount of it happening and the performance impact if there is fragmentation, one must keep in mind that all modern filesystems do produce fragmented files and that the probability of this happening increases dramatically as the filesystem gets filled.
Also, while you're mentioning UNIX: on IRIX there's a daily cronjob that runs fsr - a tool that "reorganizes filesystems", which is just another name for defragmentation. And it's not for some ancient ufs-based filesystem, no it's specifically for XFS, the modern journaled filesystem that has also been ported to Linux.
fsr_xfs improves the organization of mounted filesystems. The
reorganization algorithm operates on one file at a time, compacting or
otherwise improving the layout of the file extents (contiguous blocks of
file data).
There is also a defragment untility in tru64 and a commercial defragmenter for Solaris and HPUX, so don't tell me fragmentation is not a problem with unices. If I'm not mistaken, the official method to reduce fragmentation in Solaris is to make a backup, mkfs and restore. Sounds like a good plan to me.
There are filesystems that aviod fragmentation of files, but they suffer from mayor drawbacks: first, you have to know how large your files will be at the time you create them (or move them in their entirety around the disk when they exceed the preallocated space), and second, this method wastes lots of diskspace through external fragmentation (i.e. fragmentation of the free space). IBM's VM/CMS has something like this.
It's not just windows, the various unices (including *BSD, and linux on non x86 platforms) are also not as well supported as I would like them to be. I've looked into porting helix to Irix - it can be persuaded to compile with some effort - but I find their ribosome build-system not very encouraging to say the least.
The energy density of Hf-178m is mentioned in the wikipedia article on nuklear isomers (as opposed to molecular isomers). At 900GJ/kg you could draw 1kW from 1kg of Hf-178m for 900000000s, which is 250000 hours or 10416 days - 28 years. Your 100W Lightbulb would last 280 years.

I always thought teaching of phsics with movie would be most efficient by showing the bad examples, so people won't start to think that reality is governed by the same mad-up laws of physics as seen in most action flicks. Lots of bad examples are listed at INSULTINGLY STUPID MOVIE PHYSICS
We cannot do this with our current technology. So we have to use a work around until the technology catches up.
It's not that we cannot do this with current technology, it cannot be done at all. To properly assemble the interlaced fields of the Video signal, you have to analyze a number of adjacent fields to find out what method (weave, bob etc.) would render the best result. The only way to get no delay at all is to essentially throw away 1/2 of the vertical resolution and always use just the current field.
Note that there are flags on DVDs (but not in broadcast TV, VCRs etc.) that should make the analysis unnecessary, but there's a large number of DVDs out there that use wrong flags - so it's usually better to disregard them an look at the picture.
