Are you seriously comparing a rag tag assembly of 1000 random PCs tied together across the Internet, to a 1000 node hypercube with dedicated gigabit interconnects?
Doesn't have to be ragtag at all -- if I was faced with a supercomputing task and had the option of buying a 1024 node system or leasing the time from Sun, I might consider buying the system if I knew I could recoup investment by leasing the time. Every prospective customer is therefore a prospective competitor.
When that happens the market clearing price will drop to amortized hardware cost plus utilities.
Then follow that logic through: if Sun successfully establishes a market for leased CPU, then the Grid @ Home screensaver will come out offering to pay you some fraction of the proceeds to use your computer's idle cycles -- and presents that capacity to market at a lower cost than Sun's $1/hr.
Without a barrier to entry, this market will race to the bottom, and the price will settle out at around the amortized cost of the CPU + power and HVAC.
I think Sun has priced themselves out of the market before it even exists.
is this just another political plot to get the Mayor re-elected?
Since when is acting on the will of the people as an democratically elected official a "plot"? The mayor is honor bound to execute the will of the people -- that's what representative democracy is. If he doesn't execute the will of the people, his tenure is terminated by popular vote.
That's DEMOCRACY.
Now, as to whether the electorate really ought to resort to taxation to provide broadband access to the masses -- that's a policy matter I leave to the people of the Great State of California.
Because car thieves are not bright enough to change license plates? Sorry, RFID tags in license plates can only serve to track law abiding citizens -- they are simply too easy for criminals to circumvent.
giving everyone flat-panel monitors will probably cost you more in hardware than you will gain in productivity.
But you'll save more in power consumption. Comparing two typical 17" inch monitors, flat panel vs. CRT, shows that the CRT burns 3 times as much power. That extra 50 watts over the course of a year adds up to $33 -- which is already more than the difference in price. Figure in HVAC capacity to cool the extra 50 watts of heat output, and the savings is about $100/year. A switch to flat panels will pay for itself in just 2 years based on power consumption alone.
There is a point to this (honest): IT often has to play in cost-benefit analysis against other corporate budgets, including facilities.
Bush has never endorsed the teaching of Intelligent Design as a science rather than religion. That's simply a fabrication intended to karma bait the Bush haters. Congratulations on your success -- but you are still a troll.
"Natural selection" is simply the consequence of a series of "good" mutations.
And if we are going to bother to try discrediting ID, then let's tackle it honestly: ID cites that several species could only have evolved as a long series of fatally "bad" mutations being naturally selected. I think the examples commonly given are the giraffe and the woodpecker, species that have multiple adaptations which, taken individually, would be fatal (supposedly).
Just sitting around calling ID proponents extremists is great for our overeducated egos, but does nothing to answer their claims. If evolution can explain how the species trumpeted by ID supporters evolved via natural selection, the debate is over. If it can't, then the debate is valid, and belongs in our educational institutions.
At $0.02 per minute, consumer long distance is all but irrelevant to the telecommunications market. It's an infinite supply commodity market that is basically devoid of profit -- this is bottom dweller territory. The telcos are abandoning the consumer market across the board -- and focusing their energy on business markets and advanced services. After all, all of the profit to be made in VoIP->PSTN is in local access charges, which the traditional wireline and wireless providers will be grabbing -- not Skype.
Furthermore, Skype isn't free -- it requires internet access, and the ISPs are charging you to pay their own internet bills -- checks payable to the telcos. The telcos don't care -- they'd rather manage a few billion dollars worth of ISP business anyway. It's a higher profit market.
If you have a TV capable of playing
digital high-definition content there is a HIGH certainty that it supports HDCP.
"High certainty", eh? I'll call.
I have two HD displays, neither is HDCP enabled. (Component, DVI-D, yes). One is 3 weeks old, 1080P capable, and a brand new model. You say "hi-def" but you appear to mean "plasma". Where I live plasma displays don't work, so it's rear projection for me. HDCP hasn't penetrated that far into the RP market.
I hope the FCC votes to remove the code requirement for HF, but I also hope that a portion of each band is reserved only for those who do pass a code test. That way, they can go there to get away from us no-code schmucks who are cluttering up the rest of the frequencies.
They already have this; it's the CW subband at the bottom of every HF band. CW contests excepted, it's usually all but vacant.
If the pro-morser had been forced to enter morse on a phone keypad instead of his $200 morsing 'bug' then I'm pretty sure...
I can easily send using the membrane keys on the back of my FT-817 microphone at 20WPM. I've also built a keyer out of microswitches for less than 3 dollars that can easily get up to 40WPM. It's a no brainer.
So, your "I'm pretty sure..." comment is equivalent to most slashdot comments -- the product of total and complete ignorance.

For general purpose sorting, the number of passes in radix sort is log n (e.g. the number of digits of a decimal number is ceil(log10(number) ), so it is also O(n log n). It's only an optimization in sparse sets.
the alternative (not giving them a monopoly) results in them never giving us anything (they don't create or release the work)
I would believe this, except that I don't. By the same logic, BSD style open source software obviously doesn't exist since no one in their right mind would ever release code of marketable value to the public at no charge.
Here's a newsflash: almost all songwriters, performing musicians, playwrites, novelists, painters, photographers and software authors release at least a portion of their creative output to the public without ever enforcing copyrights or demanding compensation.
At the risk of being modded insightful by proving myself wrong, it should be noted that PKCS#7 and, by inclusion, S/MIME is subject to this sort of attack. PKCS#7 signing with "unauthenticatedAttributes" hashes the document directly.
The problem in this case isn't the hash weakness as much as the protocol weakness. If Ceasar, instead of just hashing the content that was handed to him, hashed the content + a random string he generated and then provided the random string and the signed hash output, then this attack would be impossible.
HTTP digest authentication does just this with the nonce and cnonce strings. Sure, MD5 may be weak, but digest authentication that uses MD5 isn't. So this criticism of implementors not taking this seriously is largely misplaced: most people only use MD5 in ways that aren't impacted by the attack.
When our little girl was born the doctors fairly broke our hearts with the sad news that test results showed severe brain damage. She's almost 3 now, and on the "you ask way too many questions, girl" side of normal. Had that diagnosis been prenatal, and given to a different set of parents, she might have ended up as medical waste.
And that's enough to make me spitting mad.
Executive summary: don't kill your children. They are more important than you.
After my wife updated to SP2, the HP7130 driver started crashing the explorer with every boot. Fresh reinstall worked until I downloaded and installed the latest HP driver. She had me working on it every night for a week before I finally broke down and fixed it for good.
By installing Fedora Core 3. For the first time in years, everything worked out of the box, and she discovered the miracle of Frozen Bubble and Scribus. Suddenly she became a certifiable Linux bigot. That is, until last week when my PowerMac arrived.
Mine, you hear! Now can I please use my computer again?
this article was about Linux desktop systems for the ordinary non-geek users.
My wife logs into our headless server using SSH. It is a non-geek exercise. Why does she do it? Because it's by far the easiest way to analyze apache and sendmail logs -- using a primitive command line tool called grep. It took her several seconds to learn.
The GUI is a modern 5 speed automatic transmission.
Okay, I assume this is just humor, since no such beast exists. But the analogy is apt -- a manual transmission is quite easy to drive, and is significantly more powerful. The only reason they aren't popular is that people haven't bothered to try it. I don't blame the manual transmission for incompetent drivers.

So, if I understand correctly, your recommendation is that Windows file servers should block port 139?
This problem is about escalation of threat -- now malware on a single host is capable of bringing down an entire enterprise of file servers even though the file servers themselves haven't been compromised.
The only thing a non-techical manager needs is the common sence to listen only to the people that know what they are talking about. Managers that focus on consensus building or other politically friendly, but technically agnostic strategies are destined for failure.
Popular agreement is not the same thing as correctness.
The use of password error delays and lockouts are not a solution either. For example: I have a VPN account that puts a temporary freeze on my account after 3 failed login attempts. Seemed like a good idea -- until someone actually tried to brute force my password. The result, of course, was a trivially easy denial-of-service attack that left me locked out of my own system.
Actually, open source is a big deal for businesses both large and small. I've seen some amazing startup companies deliver products that are not much more than a linux distro with config files set up a certain way -- and the product sells! Why would anyone pay for it if they could do it themselves for free? Because expertise is expensive.
As for claims by some that the GPL "killing" the software industry -- that's just silly. The vast majority of software engineers do not develop software products they develop software systems. Of the 400,000 lines of code I've cranked out, not a single software "product" was ever sold. Instead, the software system is used to generate real revenue on the order of billions of dollars a year through the service it provides. The GPL isn't hurting that business at all, in fact, it's helping tremendously. Now the software systems I build can be deployed on commodity hardware and scaled up to enterprise sizes with little cost.
Why is the GPL better than the BSD license for business? Because most businesses are software users, not sellers. GPL is the friend of the user. Under the GPL, a code fork can always be merged, and therefore the code is supportable forever. A proprietary fork of a BSD project cannot be supported after the software vendor decides to EOL it, regardless of how it fouls up your business. We've had this happen recently, and it cost us millions to code around the vendor-who-is-no-more.
A telling moment for me was in the debates, when Kerry said it was important to demonstrate that we had no long-term designs on the Middle East. Bush made no comment. Probably because if he had, the obvious rebuttle would have mentioned the huge permament military bases we're building in Iraq.
That same argument could be used to prove that America has colonized Germany. America is not imperialistic -- it's only interested in self-defense. There is a difference. If we were imperialistic, the oil fields of Iraq would be pumping out America's New Source of Free Oil.
