Honestly cable should be crystal clear.

Of course the best part of all this is that to keep with the bazillion different cable channels out there, and the limited (125 or so) RF channels that they also have to share with cable modems, they try to cram as many sub-channels on the same RF channel as possible, at least 10 or so for SD channels, re-compressing them to lower quality. Meanwhile, my antenna gets a full-quality HD signal that maybe only has to share with one or two SD channels. (FWIW, I think cable QAM gives twice the bit rate per channel as antenna ATSC, but still.)

Comment Re:DC power (Score 4, Informative) 223 223

The main advantage of AC is that you can use higher voltages safely, and higher voltages mean higher wattage with the same wires. And bigger wires are more expensive.

AC versus DC load breaking comparison with a knife switch

That was 220 volts, but 110 volts isn't much better on the DC side. There's a reason why DC-powered telecoms equipment uses 48 volts; much more than that and switches start arcing.

Ohmic loss is an issue when DC power is transmitted over power lines, but not so much when the DC is generated in the same building (solar panels, etc.).

Comment Re:Danger keys (Score 1) 675 675

At work I have to use Windows. (At home I use a MacBook Pro so there are basically no danger keys.) While currently I only have the keycaps for F1 and INS removed, in the past I have also pulled F12, caps lock, and the Windows/menu keys. I just leave them in a small plastic bag next to the keyboard.

I don't know how you missed the Windows menu key, since it yanks focus away from your current program if it gets tapped by accident, then you have to waste time getting back to normal. It's almost as bad as F1.

The insert key is bad if you have an editor that tries to implement "overwrite mode" in a mouse-based text editor, which is pretty silly. It can also rarely get engaged by pressing the keypad zero key under certain conditions. (like with the shift key hald down, I think)

Actually there is one important danger key with OS X. I don't know why UI implementers insist on being able to do all sorts of file manipulation functions in contexts where you are supposed to be selecting or viewing a file (instead of, you know, switching to the file manager program), but they do. Windows goes out of its way to support moving and deleting files when you need to select a file, and various OS X programs insist on deleting a file whenever you hit command-delete (aka command-backspace).

The problem is that command-plus and command-minus are used for zoom in and out. (Very useful in the Preview.app image viewer.) Be off by one key when zooming in, and your file is suddenly moved to the trash, and its window (if it has one) closes. In a file viewer program. WITH NO UNDO AVAILABLE. WTF. Now you get to fish it out and put it back where it belongs. At least it also insists on playing a (non-configurable!) sound when it does that, so you can have some idea that something has happened.

Comment Re:Wait.. WTF... There's a SAFE that runs WIndows (Score 1) 147 147

Apparently because it's some sort of "drop off" safe.

In the normal operation of the safe, the majority of operations are executed by way of a touch-screen on the safe. Once the money has been inserted into the safe, it is automatically deposited to the retailer's bank, which means that it's the bank's money and a store manager cannot remove cash from the safe. Typically, to remove cash, there is a requirement for both the store manager and a Brink's employee to be present.

That still doesn't explain why people in this sort of industry think you need Microsoft freaking Windows for a simple UI screen. Perhaps they are using Visual Basic? (rolls eyes)

This is 2015, folks, this is the kind of crap you can do with a Raspberry Pi, and if it's long-term support you want, you will still be able to get boards ten years from now, at most needing software changes in the form of a few different kernel drivers.

I suspect that all the automatic exploits on SSH these days are expecting x86, if for no other reason than that the botnet people don't want to have to support too many architectures. I have an old Mac G3 (the blue tower) running 10.4 that I am still using as an internet server (I plan to retire it in a few months when other stuff isn't a priority), and every now and then SSH is wedged and won't connect remotely. I suspect one of those "automatic exploits" every now and then manages to hit a bug in that version of SSH which locks it up without a proper crash.

It's just HP ES, formerly EDS, that are required to dress like that. I am also guessing it's just the customer facing team.

If this is true, you needed to be modded up. EDS is the IT services company that was started by H. Ross Perot, and if they're only asking it for the customer-facing people, then why the fuck hasn't it already been in place for years?

But TFA says "R&D", which doesn't sound like the kind of stuff I would expect from the EDS folks.

Submission + - There Is No Honeybee Crisis-> 1 1

iONiUM writes: An article today claims that there is no longer any Honeybee crises, and that the deaths of the Honeybees previously was a one-off, or possibly non-cyclical occurance (caused by neonics or nature — the debate is still out). The data used is that from Stats Canada which claims "the number of honeybee colonies is at a record high [in Canada]." Globally, the UN’s Food and Agricultural Organization says that "worldwide bee populations have rebounded to a record high." However, many corporations and pro-environment groups have much to gain by creating a panic about Honeybee deaths, and as such continue to publish stories claiming the situation is dire.

Submission + - Ted Cruz is a 'Star Trek' fan and that is a good thing->

MarkWhittington writes: Just to prove that he is a multifaceted character, Sen. Ted Cruz, R-Texas sat down for an interview for the New York Times Magazine and opened his mind, not on matters of high policy, but on comic books and science fiction. As a lad, he liked Spiderman and Han Solo. But it is in the realm of “Star Trek” that the presidential candidate may have created some controversy for himself. He very much prefers Captain James Kirk to Captain Jean-Luc Picard. There are Star Trek fans who will argue passionately for either Enterprise skipper. But then again, some Trek fans will fight over what angle Spock’s ears protrude from his temples.
