Submission + - $340 Audiophile Ethernet Cable Tested->

An anonymous reader writes: Ars Technica has done a series of articles that attempt to verify whether there's any difference between a $340 "audiophile" Ethernet cable and a $2.50 generic one. In addition to doing a quick teardown, they took the cables to Las Vegas and asked a bunch of test subjects to evaluate the cables in a blind test. Surprise, surprise: they couldn't. They weren't even asked to say which one was better, just whether they could tell a difference. But for the sake of completeness, they also passed the cables through a battery of electrical tests. The expensive cable met specs — barely, in some cases — while the cheap one didn't. It passed data, but with a ton of noise. "And listeners still failed to hear any difference."

When I upgraded to Windows 10 yesterday, there was a screen that came up that asked me if I wanted to reset the default apps. I said no for my browser and media player, and when it completed, Chrome and VLC were still the default applications. I think it's a little underhanded, but not as underhanded as the article suggests.

Mozilla is whining anyway; when they switched search providers from Google to Yahoo I had to go through and specify it on EVERY INSTANCE of Firefox I have. Since I use --no-remote and segment my web browsing this was actually a royal pain in the ass. Granted, Google was the old "default," so I had never changed it, but it was still an undesired change in behavior. If they're going to whine about Microsoft doing the same thing then they ought to look at their own behavior.

Firefox is still my browser of choice for personal use but for others I've started to recommend Chrome. It's just less hassle to support it for your luser friends. The future of Firefox and Mozilla is not an encouraging one, which is a pity.

It's a bit hard to get outraged at MSFT when GOOG has been doing the exact same thing for the last three or four Android versions.

It's called an "inverter" air conditioner. It produces a variable-frequency AC sine wave from the DC voltage. The variable-frequency to the compressor changes the cooling output, so instead of turning the air conditioner on and off as the temperature wanders back and forth across the set point, it varies the frequency to keep the temperature steady.


It is brilliant.

Sharp already sells these air conditioners. They're just removing the DC rectifier circuit and running directly on DC instead of starting with 50hz or 60hz AC.

High AC voltages have induction losses. They don't travel as well as low voltages.


The goal is to send lots of watts, not lots of amps or volts. Low amperages travel well. High amperages don't travel at all -- they lose most of their energy to heat. Simple transformers (which are basically just coils of wire) can swap amps for volts so that lots of watts can travel a long distance at low amperages.

Basically, Sharp is eliminating the rectifier circuit from one of their existing products. Sharp currently sells it as an 'Inverter Air Conditioner".

Unlike most air conditioners, inverter air conditioners are always-on. The inverter varies the -frequency- of alternating current sine wave in order to change the cooling output of the air conditioner. It continuously outputs just enough cooling to maintain a steady temperature in the room.

To do this, the A/C converts the incoming wall power to DC and then back to variable frequency AC. Eliminating the initial AC to DC conversion here makes good sense.

That's not destruction of property, that's maintenance of property. Want a better analogy than the soccer ball? If your neighbor parks in your driveway without permission you can probably have him towed. What you can't do is take a 9 Iron to his headlights.

No, that would still be destruction of property. The fact that it's on your property does not give you the right to destroy it. If the neighbor's kid kicks a soccer ball over your fence does that give you the right to slash it with a knife before you return it to them? Of course not.

This is a loser of a case. If the annotations are official legal guidance of the state of Georgia then it's not copyrightable. If they're a third-party creation owned by a third party then Georgia has no standing to bring suit. That's for the third-party to do.

Sounds like they're playing fast and loose with the rules.
