From reading the cached article it claims that Minkowsky won in that as the above poster cites that the photon momentum is proportional to the index of refraction "n". However, if that is true then wouldn't the substance move in the opposite direction of motion of the photon to conserve total momentum since the photon momentum is increasing since the index goes from 1 to >1 ? This is opposite from what the fine article claims.
Sure, I feel sorry for you, but you could have used the Consolidated Omnibus Budget Reconciliation Act (COBRA) to continue your group health care (at your own expense). Therefore, you made a choice and unfortunately you gambled and got bit by the consequences.
Now you're griping because some other insurance company doesn't want to pick up a pre-existing condition. Why should they? It was your choice not to have health insurance. They're under no obligation. Would you buy a used car or house with serious problems? No, so why expect someone else pay the cost for your own choice.
This was one of those products that could have been bigger than M$, if they hadn't botched it. For details go look at
the wikipedia article:
GEOS (16-bit operating system)
It was a better windows than windoze and it just kicked butt over MS Windows 3.x at the time. GEOS was originally developed for the C64, but later rewritten and ported to the PC with an integrated a word processor, spreadsheet, graphical filesystem view, scalable fonts, and it just never crashed.
What killed it was that they sold the SDK for far too much (I think about $200), which meant that casual software developers and students wouldn't pony up the money and create new shareware/freeware for it.
That and that Micro$oft had leveraged their position to extract exclusive OEM contracts forcing the OEMs to pay for a windoze license for every machine they sold regardless whether they installed windoze or not.
Coincidentally there's a recent "How To" on how to fix a scratched CD at http://www.wikihow.com/Fix-a-Scratched-CD The nearly last ditch effort is to use vaseline (a lot like hair gel). However, it's not a long lasting solution. Just long enough to burn a new CD.
Of course, I know a lot of people don't agree with me. But that's no surprise, they mostly object to my calls to repeal (among others) the 17th Amendment and restore a true federal system.
I whole heartedly agree with you on this. The 17th Amendment made the senate to be popularly elected just like the house. We should also amend away the 16th, which gave the Federal govt a direct hand into our pockets. Then the Federal govt would have to get its funds and be answerable to the states, which provide better oversight than what we have now.
Eliminate both of these amendments and we can re-establish states rights and better Federal accountability.
I'm amazed at the amount of vitriol over OpenDNS's offering also. You don't have to use it if you don't want to.
I guess I'm a little more trusting of them, because I use their other service http://www.everydns.net/ which provides FREE DNS service. They're one of the few that do (the only one I found at the time that actually worked and was updateable). So I can get my domains from GoDaddy.com for cheap and have the DNS served via EveryDNS.net for free (you can contribute if you want, I kick them about $20/yr).
I don't notice any performance problems, because I run my own local caching named server where the forwarders are set to the OpenDNS servers. But I like the that they will resolve misspelled domains. I haven't really used any of the anti-phishing aspects... I generally don't fooled that way.
I'm surprised that no one has made the obvious reference to the 1975 movie with James Caan named "Rollerball", where he, as the main character Jonathan E., goes to the library to find the history of his, then, current world dominated by corporations. The contents of the entire library and the sum of all human knowledge has been "saved" into this watery mass storage unit, prominently shown bubbling in the background. However, as with other WORN (write-once-read-never) archival data systems we've all come across at one point or another it has some problems...
Jonathan E.: So the computer misplaced some information? Librarian: The entire of the 13th century.

TFA lists two areas of concern: 1) the denying of grants and funds for non-alarmist climatologists, 2) the double standard meted out to submitted papers. Alarmist papers are accepted readily and non-alarmist papers are rejected as being "not interesting". When non-alarmist papers are accepted they are not given the same opportunities for dissenting response.
Therefore, the poster you are attempting to discredit is quite right. The issue is not necessarily the funding of Lindzen, but the issues he raises that is there is no longer a healthy or balanced debate (the scientific ideal) on the global warming issues, and that they've been co-opted by special interests and that is the "if it bleeds... it leads" in the newspaper parlance.
After browsing through the article, I find that most distribution reviews focus on the wrong aspects... talk about the "spiffy" new interface, and "cool" looking this or that. In this case the login manager and the desktop, etc. What a waste!
I stopped with Fedora Core 4, and went on to try Ubuntu 5.10
for my satellite machines that require a minimal disk with OS, and use NFS (for the home directories), NIS (for authentication), email (routing), PostgreSQL, DNS, gateway, etc. from my main server machines.
I usually start with a clean disk and just reload everything (this was one nice feature of Fedora). The last "stable" Fedore was Core 2 though, since then I found that there were just a multitude of little problems getting NIS, NFS, almost anything, to work.
I still like the Fedora way of installing packages and updates, so for a quick or specific purpose machine I will use CentOS, where I can expect updates well into the next decade. Fedora leaves me an orphan after a year or so. So I'm trying Ubuntu, which I have found that things are better tested and integrated. There's still a few "gotcha's" but for the most part I hadn't had to spend hours and hours trying to get NFS & NIS working. However, we'll see the true test comes when the next Ubuntu arrives. Instead of the clean disk approach, I will be using the full update capability, because Ubuntu just installs the minimum and requires me to pick and choose the packages I want or need.
Anyways, the bottom line is that I care diddly squat about how the distribution works! I care how well it integrates with the other Unix services like DNS, NIS, NFS, printing, email, etc.
At least they're making fun of their stupid people, we tend to put our morons on pedestals.
Yea, we call them celebrities and we throw lots of cash at them for whatever they do or say. Then they actually think that because they have this spotlight and all this fame and wealth that they have some deep profound insights that they insist on inflicting upon the lowly non-celebrity (i.e. the rest of us... especially those who post on/.... you know if we had lives of our own we would be too busy posting inane comments here or anywhere:P )
Anyone remember Pacbell's (aka SBC) 80's statement that "Fibre to the Curb" was just around the corner. Well, I'd say it's just about time.
I remember. PacBell was progressing quite nicely and was about 6 blocks (and a couple of months) from doing my San Jose, CA neighborhood. I would have jumped at the chance to have it. They were promising telephone,broadband, and video service all in one package and would have been comparable or less in cost to the total of the phone/DSL/cable or dish bill with much better bandwidth or reception.
Then SBC bought out PacBell and promptly stopped any further installations and dropped all their current fiber customers, because SBC didn't care for any of that high falutin' technology... they just wanted to deal with POTS (and squeeze as much as they could from their existing customers).
I remember, and I won't hold my breath either.
(Side note - you would think that here in the heart of Silicon Valley that we would have pretty good bandwidth... it's been a constant battle to find a stable DSL provider. I know use SprintBroadband (wireless), but they aren't adding any new customers or improving service. Go figure!)
There's an interesting opinion piece in the Mar'2004 Physics Today by Mohamed Gad-el-Hak
http://physicstoday.org/vol-57/iss-3/p61.html
concerning the glut of papers and journals that litter the scientific research landscape.
The problem he addresses is that generally the research and university bureacracy has promoted a ``publish or perish'' mentality, where it's not the quality of work (or how often a work is cited) but how many papers are published that earns a researcher respect (or more earnings, grants, etc.). He illustrates a engineering dean that published on average a paper per week for a one year period. Admittedly, I suspect that most of the papers were actually written by graduate students or post-docs, but it does highlight that how much of that prolific output was new or novel, much less interesting!
Perhaps, going to a author-pays system may have some beneficial side-effects of reducing the amount of cruft that passes for a research paper
nowadays. An author would have to balance his need to publish with his resources. Is the content worth it?
I no longer do physics (I'm a software developer now) because I could see the trend that it didn't matter what you wrote, but that you wrote a lot of it. I still toy with the idea of going back and doing some novel research. However, if I do, I intend to publish it on my own website, since I have no need to pad my resume' with a long list of publications, I would just want to get the results out there and indexed by google or other search engines, so anyone who cares and is looking could get instant access to it.
For those who are concerned about this concept of author-pays limiting the exposure of unknown or young researchers, they would have this option available to them also of posting their own work and letting their pool of peers discover them.
If their work is truly unique and well done, then their standing will increase.
So I was thinking - I like games, she likes to talk, why not combine the two?
I can just see it now. ``Hey, honey! We need to talk about our relationship.''
click, blast, explosion!
``Sorry, sweetheart, I just accidentally killed your character. Please, reset and connect up again.... losing your connection... we'll talk tomorrow.''
I agree with many of the other comments here. It looks like the boy is added to the one photo, because the shadow doesn't look large enough to match the boy. However, the picture with only the tank is this same picture with boy's image removed. Some of the tank's equipment is missing from the front, and the scene through the underside is too regular.
Let's get out our media consipracy hats on. It looks like someone with some political agenda (obviously to discredit US government policy) takes a regular photo of a tank on a street and does a somewhat easier & credible job of adding a boy on the street in front of the tank. Oh, those evil American soldiers are going to run down that cute little boy. How nasty!
They also release a photo, which is clearly doctored to show how the US government is covering up their atrocities.
I have no idea where the photo(s) came from but if they're being put out to the (gullible) media then it accomplishes it's intended slant.
However, it could have been done by a secret US government agency to discredit and reduce any sort of confidence in the media outlets...

Does anyone have a good understanding of the underlying physics? I'm a little tired of wading throught the troll-bait of the postings here which just decreases the signal to noise ratio.
One point that came out in the article was that the signal was being transmitted from an array of antenas and received by an array of antennas. This says to me, that they're using the phase shift of the signal somehow to increase the bandwidth, but if the transmitter array is only a half-wavelength in extent then the phase shift in time is only on an order of 1ns. (I'm assuming the wavelength is comparable to the size of a cell phone... I'm a software geek and I wouldn't know the typical cell phone frequency.)
Note that the printed Domesday Book, on which the digital project was modeled, is still quite accessible after almost 1000 years.
I don't know about you, but not many English speakers can still read/decode old middle English.
I haven't tried reading the Domesday book myself, but if it's anything like Chaucer, the spelling is dynamic (i.e. not even consistent within the same document) and obscure by even modern English standards. Let alone the language itself is far different from modern English.
Therefore, saying that the original domesday book is still accessible is like saying the that all my old C64 files are still accessible because I still have the 5.25in floppies. (Note: the C64 floppies had varying number of sectors/track depending how close the track was to the hub... these floppies can't be read on a DOS machine.)
Slashdot Mirror
From reading the cached article it claims that Minkowsky won in that as the above poster cites that the photon momentum is proportional to the index of refraction "n". However, if that is true then wouldn't the substance move in the opposite direction of motion of the photon to conserve total momentum since the photon momentum is increasing since the index goes from 1 to >1 ?
This is opposite from what the fine article claims.
