1) It has to be portable to all machines I own, in perpetuity, with only minimal check-in/check-out at a central server.
2) It has to be inexpensive. $0.99 is too much, when I can get used CD's for about that price with better quality. We should be getting a break based on the fact that we're buying a poor quality copy with essentially zero shipping costs. We're not.
I don't buy iTunes, though I'm still using their initial 5 free. someday I'll burn a CD of my purchases.
If the model is too large and complex to reproduce in that way, then I would question whether it's science at all...
One can. And one does. However, the type of model I'm describing is very similar to the climate models described above. Whether or not it is SCIENCE, it is widely held to be so by all major universities and government funding agencies. My opinion is a bit more skeptical, but I know where some of the skeletons lie.
If you're saying the problem is too complex and should not be attempted, then I might agree. Otherwise, I suggest you go here and simplify things for us. And I'm sure there are still some bugs.
The attached model has been under continuous development for about as long as Windows... probably longer, though with a much smaller budget. It is one of about 5 such packages in the world today. Casually whipping up another such model is not in the cards.
Bullshit!! I have repeatedly seen glorious pictures of beautiful ocean models, only to discover, after a few months of working with the scientist in question, that they have artfully underemphasized the failings in their models, while, at the same time, being perfectly accurate in their description of the algorithms. It's only when you use their tools that you understand their errors.
We're using one of the most commonly used ocean models in the academic world. Bug reports, some extremely serious, but not catastrophic (crash-inducing) come out monthly (for example, failure to solve horizontal diffusion). In a standard academic paper, I can barely fit all the partial differential equations for these models, let alone the particulars of grid discretization and the choice of high-order solution schemes for spatial and temporal derivatives, some of which vary depending on the nature of the quantity in question.
If you have my code, you can tell exactly what I did.
Scientists do not have large code shops. One recent project focused on modeling the entire west coast from Baja to the Bering Straits and had about 6 programmers at 4 institutions in 3 time zones. All had multiple other responsibilities and only three understood most of the code (I am not one of them and none of us realized we weren't diffusing); none of them had a system administrator or technical support. The release version has O(10e5) lines of FORTRAN 90 code.
Yes, but is the debunking peer-reviewed, or is it some crackpot in the back end of nowhere splashing up a web page becuase he's peevish and doesn't get out enough?!
As an academic computer programmer in ocean modeling, let me just say it HAS TO be open. Yes, my work is open source, though why anyone would WANT my code is beyond me. Most of what I do is quick, short-time, badly coded, inefficient data processing and vizualisation scripts. Still, feel free to email me and I'll send you a tarball of any code on my machine or a link to the developer's page.
1) Science functions only on open review. If you can't duplicate someone's results, they are useless (c.f. Ponds and Fleischman [sp?]). A scientific result is only of value if it describes a consistent replicatable process. This is why I consider the closed source work to be completely meaningless. It may be perfect, it may be bug-ridden garbage, we'll never know!
2) Every tax paying American has paid for my code and work. While I regularly feel they're not getting their money's worth, I definitely don't feel they're paying me to enrich me. They are, in a very real sense, my bosses, and I AM obligated to report to them, if they care. Think of it as a company requiring rights to your work.
3) As an academic working on a fairly limited budget, open source and free software have been a godsend for me and everyone else I know. We run linux because it's more efficient, secure and FREE; we use free or open-source compilers; and we cobble together high-perormance computers and beowulf clusters out of miscellaneous bare metal and lots of googling. The only piece of software I routinely have to pay for is MATLAB.
So, sign it, then add "See ID". The signature IS there for verification, and good clerks will request the ID. If they're really sticklers, then just sign the slip with the "See ID" in your signature and claim that that IS your signature!
Anyone know if the torrent is the German version KNOPPIX?
Been holding out on trying remastering and USB install until this came out, but my high-school german is fairly rusty.
WHOIS doesn't show gcal.com or gcalendar.com registered to Google, yet. And at least one is owned by a fairly legitimate business. The other is oddly FUBARed.
And yeah, I'd love it if all meshed seamlessly into SunBird, Gmail, and iCal.
Actually managed to copy the files from CD (not iso) onto a windows hard drive, then downloaded Grubd and mucked around with one or the other of the menu.lst files in there. The result is that:
Boot Windows into modified boot.ini
Options are Grub or Windows (from c:/boot.ini)
Select Grub, Options are memtest, a minimal dos (sorta handy), Windows (iterate) or various Knoppices.
Result, Knoppix completely contained in a windows directory, no CD's or boot disks required. And no LILO, which I've never really liked. And, more important for me, no downloading an iso over a slow home network onto ancient hardware.
YMMV... I wasted a fair bit of time doing this on an old P2 - 350 I had lying around. A lost weekend if there ever was one!
If only one recording company owns the rights to the Beatles, then they can charge whatever they want for a copy of a CD. The commodity is not music in general, but a specific performance or song.
I speculate that the RIAA and Associates would like to narrowly define the recordings as property when it comes to their ownership. Then, when you buy it, it's not property, but a license to play. And when they exert complete control over it, it's not a commodity, but intellectual property.
The point behind this gas tax is that, on average, a N-ton vehicle burned X gallons of gas per mile.
Yep, and the damage done to roadways is largely proportional to N, which, incidently, is loosely proportional to X. So why should my 2000lb ~40mpg 10 yr. old Honda Civic be paying as much per mile as a 6500lb ~15mpg Ford Valdez? We should also tax more if you use 4 wheel drive, use studded tires or load you car more heavily on average?
And, incidently, why is it that even Honda hasn't really built a higher efficiency car since the 94 Civic?
Finally, the 900 lb gorilla in this argument; twice the mileage equals half the pollution. While gas taxes are ostensibly NOT a pollution tax, this very explicitly decouples the two.
Now with hybrid cars shifting fuel burning to nuclear power plants (Dream world, sorry)...
Just so as we're clear (sarcasm filter malfunctioning, pedantry on), hybrid is still gas burning; unless you do some really tricky, warranty-violating rewiring of a current hybrid car (a great concept IMHO) you will NOT be able to plug it in.
As far as I know, there are VERY few electric cars for sale in the US. Most that were in production have been pulled back from their lessees... even those who dearly wanted to buy them. I wonder why?
"Mafia tactics": you pay us or we hurt you physically.
BSA tactics: you pay them or we hurt you financially.
Yes, the BSA is enforcing legal licenses (albeit, IMHO, draconian, and legal only under our current business-subservient patent system), but otherwise it really is the same thing. The mafia provided a service; a group of thugs wouldn't drop by and ruin your business. The BSA prevents a group of lawyers from stopping by and ruining your business.
The cost of litigation, even when you are in the right, is a far more dangerous weapon, in this business climate, than a baseball bat. A lawyer can impoverish you for years, a baseball bat is likely just to involve some transient pain and medical expenses.
If the audio quality is good and the setup is easy, this is golden.
Yes, I'm buying... when the inevitable undersupply problem dies down... after the first round of bugs is worked out. I've been looking for a PC small enough to take home, but didn't feel like splurging on an ibook... yet. At this price point, rebuilding my old P3 with a new case and drives suddenly seems more like a waste of time and money.
Anyone bothered to try to figure out the absolute amplitude of these oscillations? Even from the picture, I suspect you're talking about an object moving in a sinusoidal path, quite possibly of short wavelength and LARGE amplitude. There's energy and aceleration associated with such behavior.
Need to know distance to meteor, speed of meteor and some estimate of field of view. Then calculate the width and length of the "wobbles". Some enterprising physics student could then calculate how much acceleration the object is going through at the top of each arc. I suspect the answer is a very large number.
As an aside, I think the falling leaf/penny analogy is WAY off. Falling leaves are turbulence dominated, whereas this thing is presumably supersonic, leaving its turbulence way behind.
a $200 PDA with video and MP3 playback and 30GB of storage
Ok, so it's not perfect, but if it's capable enough, it might be a great travel device. Plays lots of tunes, edits text, goes wireless for email in coffee shops and fits in a pocket.
Seriously, I'd love a small, cheap, underpowered laptop, just enough to fire up mozilla, xmms and thunderbird. Even my 800MHz P3M can't handle video on battery (speed stepped down to 700 + funky video chipset).
As the proud owner of an Archos Studio 10... well, ok, it's shite, but it still works and makes a decent USB drive (though it has never worked off the plug), I can sort of recommend Archos. I'll keep my wallet in my pocket for now.
Well, my old office had a 15" (1024x768) LCD side by side with a 19" CRT running at ~80HZ. My eyes hurt less if I did all the text processing on the flat screen.
Yes, the CRT had higher resolution. Yes, it was bigger. But I really only used it for graphical displays. The crisp edges and absence of flicker on the LCD more than made up for the pixellation.
Just my opinion... perhaps it was the Linux drivers for my Matrox card, or Xinerama or... but I won't be buying anymore CRT's.
Some random link chasing gave me:
linuxdiving.org
and
somebody's mac page. Looks like some Suunto and Uwatec support, though it's "pretty thin", and the info is sort of evenly split between Mac and Linux.
If you're a true diehard, you could always try a windows emulator, or WINE if it's available for Apple, though I guess that misses the hardware issue. Ok, that's getting twisted, never mind, I'll go home now.

Been there, done that, they (emperors) didn't care much, though we weren't in the group responsible for tackling and imprisoning them. Nor do they care about 2-cycle snowmobile motors or large red Snow-Cat like vehicles. The penguin research group actually had several wander up to their enclosure, wait patiently, then walk in when someone opened the door.
Adelies were a bit more skittish, but even they would stroll up and give you a good looking over from a range of a few feet.
DISCLAIMER: No penguins were harmed in the filming of our research!
