I bought an OkiData B4200 printer. The refill cartridges are so cheap that nobody bothers to even compete with Oki on the refills. A toner cartridge good for 5000 pages is about $35. You can't beat that with a stick, so even with good laser paper, my TCO is only about 7 cents per page.
My Oki color laser is just as good, at just about 35 cents per color page. The carts are slightly more expensive, and there are 4 of them, but they last a LONG time. Oki charges more for their printers, but the consumables are much cheaper. I think they've caught on that the older business model is much better, not just for their customers, but for their business as well.

If you google for "speed of light" you get "News: Measure the Speed Of Light With Your Microwave - SLashdot - 2 hours ago"
Complete with (incorrect) overusage of CAPS and everything.
This experiment has no place outside the elementary school classroom. In fact, I think it has no place even there, because this method will be so wildly inaccurate that kids will learn the wrong speed of light.
Is it a wonder education is going to hell? We keep coming up with stupid, irresponsible "hack" methods of science that teach people the WRONG thing because we're spending too much money service the national debt to afford decent educational tools. Of course, it doesn't help that the "Educational" price for scientific instruments is often 2 to 3 times more than the "corporate" price - companies sucking at the government teat, of course.
"Superintendent Chalmers, thank you for your request for purchase of a time-domain reflectometer for use in your science classroom.

"A DC-DC converter converts one voltage (battery voltage) to another (operating voltage). They often work by converting the DC signal to AC oscillations, transforming, and then back to DC."
The theory behind DC-DC conversion is pretty simple... You have an Inductor with is a "Constant Current" device. On the input, you have some higher voltage than you want to have on the output.
You also have an in-line switch that can turn the input on and off very quickly. We all know that the average voltage of a square-wave is basically the amplitude times the duty cycle, so the switch is modulated on and off (PWM) to give a square wave with an average DC value of the desired output voltage.
When the switch is on, the current in the inductor rises as energy is stored in the field. When the switch is off, the inductor attempts to keep the current constant by drawing current up from ground through the body of the bottom FET switch or through a schottky diode that is often placed there to lower the forward voltage.
There is also an output Cap, which is a "Constant Voltage" device, to store energy coming out of the inductor.
If you want to think of it from a signals perspective, you have a square wave, which consists of a DC component, a fundamental, and a bunch of harmonics. The L-C circuit on the output is basically a very low frequency low-pass filter that filters out everything above the DC-value, leaving only the DC voltage that you want.
These are very efficient circuits, but you have to be careful to choose an LC network that is not resonant at your switching frequency.
Oh, and while you're in there, replace any aluminum-electrolytic caps that might be in there. The electrolyte can dry out, which may also cause audible noise. Replace them with Aluminum-Polymer caps from Cornell-Dubilier...
This sounds like subharmonic oscillation in the inductor core used in the DC-DC converter. Pop it open, find the inductor, and replace it - thing should be good as new.
" or possibly 2 or even 1 ohm (doubles and quadruples the power figure, respectively). "
This isn't really true. The maximum power is delivered to the load when the load impedance is the complex conjugate of the source impedance. Assuming our amplifiers and speakers are purely real loads (which they aren't, usually), that means that the speaker impedance should match exactly the output amplifier impedance.
What you have to do is look at the system as an ideal voltage source with two resistances, Rout and Rload, in series. If you figure out the power in each resistor, you'll find that Pout (the power dissipated in the amplifier output) is equal to Rout * V^2 / (Rout + Rload)^2. The power dissipated in the load resistance is Rload * V^2 / (Rout + Rload). Here, V is the output voltage of the amplifier. If you graph these, you'll see that the power dissipated in the load is at its maximum when Rout == Rload.
Usually, the power numbers given for car audio are for something like a 1ms burst at 1KHz into an ideal reference load that matches the amplifier perfectly. It's dishonest as all hell, which is why the FTC needs to bring back true RMS power measurements.
I'm sure the British Spam police are going to go really far out of their way to nab spammers who operate from the Cayman Islands or other places not within the borders of Great Britain...

That an article bitching about military technology is using one to propagate itself.
Hello, DARPANET!?! Anybody home?!
Do you think that the transistor was invented because someone had a vision for consumer products? Of course not - they wanted non-mechanical switches that would withstand the physical abuses of military applications.
Do you think we went to the Moon because of curiosity? Hell no. We used the Moon to instill curiosity in the public to justify spending the money to develop long-range missiles capable of delivering payloads.
Do you think we invented radar to look at the weather and control commercial air traffic? Of course not. We invented it so we could see our enemies coming. Interesting sidenote, we did see the attack on Pearl Harbor coming, but the cloud on the radar was so big, the radar operator thought it was an error and didn't report it.
Do you think we invented Kevlar and Spectra for better brake pads? Light-weight projectile-tolerant panels, my friend...
The list goes on and on. 90% of the crap we use in our everyday lives was invented for some military purpose, including the Internet.
I know I'm going to sound like a conspiracy theorist, but does this actually make any sense?
The stories published yesterday said these people a) paid for a service that we all know doesn't charge, b) the kid, who allegedly lives in low-income housing, is an honor student and either didn't know or couldn't figure out what was going on.
This story is a flash in the pan, and I think that it's conceivable that none of the people involved do indeed exist. RIAA "had no personal information about [the defendant]" yet was still able to file a lawsuit? How the hell does that work? How do you serve papers to someone if you don't even know who they are?
Did it ever occur to anyone Reading the article that the reason they won't return sales calls is because they know that if they ever actually sold a license, they would be committing a blatant and egregious violation of the law? It is against the law to sell something that you cannot prove that you own, either through reasonable assumption or by legal title.
If I'm having a yard sale, a buyer has reasonable assumption that I own the things that I'm selling. If I'm selling a car, I must show that I have legal title to that property.
"Intellectual Property" as it is called is the same way. SCO cannot claim reasonable assumption and they know it because both a copyright and a license are sort of legal title. They've been tempted to try, but I think their lawyers know that if they do, they will be in a very bad position (as if they aren't already).
Everything about the code in question says that it is freely available. What they're doing would be like someone flying over to my house from Utah and claiming he/she owned 90% of the crap I was selling on my front lawn. While 1 out of 100 buyers present may be frightened into giving him the money instead of me, the other 99 would be able to reasonably assume based upon the "plain-view" evidence that the visitor from Utah was full of shit.
I am guessing this is why they waited so long to sell the licenses..
I'll bet you also blame the female jogger who gets raped because she's wearing provocative clothing and jogging alone at night, right? After all, it's only instinct for the sexual predator to go after easy and lucrative prey, right?
Sorry, but I just don't understand blaming the victims of crimes. Just because a security hole is there doesn't mean it deserves to be exploited.
We pay more tax now than we ever have in the past. It just gets wasted in government...
I went to high school in New Paltz NY, and during my time there, over 2 million *DISAPPEARED* under the watch of a certain superintendent. While no charges were ever filed, he was summarily dismissed with several years' pay and a new Acura. Talk about government waste...
The $400 hammers and $1800 toilet seat covers don't help either, nor do the 18 welfare checks that go to the non-existent person with an anonymous P.O. box...
Government waste, which includes fraud by government contractors, I *speculate*, probably accounts for fully one half of every tax dollar spent.
In the company that I work for, it is each employee's responsibility to install patches that come down from IT. Failing to 1) keep up to date on all patches and 2) keep up to date on virus definitions are each grounds for immediate summary termination, including a free security escort to the door.
They remotely check machines every week at random times...
I wish I still had some mod points to mod the parent up. He's absolutely right. It is not necessary to have all 4 components of office installed. You can buy Excel, Word, Powerpoint, or whatever, separately as standalone products. In the interest of fairness, it's not appropriate to go bashing "5" bugs when in reality there are only two.
There's a line item on all companys' balance sheets called "Accounts Receivable" that contributes to the bottom line. Companies are allowed to consider the value of A/R in their profits, as if they had already been collected.
There's another line called "Bad Debt," which I assume is going to explode on SCOX's balance sheet about a quarter after their "A/R" line explodes....
Pump up the profit, sell off the stock, watch the company fall into deep red ink, laugh all the way to the bank...

Even more - check out that fuse on the back of your HOME stereo...
I see many "500 Watt" home theater receivers that have a fuse on the AC line that will blow at 3 amps, which is just 330 watts in the U.S.
I wonder where all of that extra energy is coming from...
