There's actually an even dumber reason than that.

The RTG on New Horizons was a spare from Cassini. It was very much "use it or lose it" as finding more plutonium for a RTG is getting more difficult every day.

Oh c'mon, you're trying to tell me that *nobody* at NASA had the common sense to call a few Libyan nationalists and order some used pinball machine parts off of Amazon?

Charged particles are not magnetic. The electric current caused by the electric current creates a magnetic field. Basic electrical magnetic property. There is a magnetic field because there is an electric current traveling through the atmosphere which does impose an electric charge on suspended insulated objects in addition to the induced electric current in conductors on and in the ground.

The amount of induced current is directly related to the rate of flux change producing an AC current provided one end of the conductor is grounded. At the low currents and large area of very long lines, this AC component is relatively low in relation to the DC current brought in at the poles seperated by our earth's magnetic field. A static magnetic field does not induce a current. A steady DC current does build high currents in long suspended conductors.

http://en.wikipedia.org/wiki/E...

Even high voltage transmission lines are now protected by adding a resistor to the center tap of a 3 phase transformer to ground to limit induced current. The transformers already MUST have a ground refrence already due to the DC charging of the lines that would happen if there were no ground. This is why transmission lines never use Delta transformer to Delta transformer. One or both ends of a transmission line have a substation with a Y connection with the center tap grounded.

I know of one BPA line that is Delta to Delta, but in addition to this there is a 3 phase Y transformer to nowhere that only porvides the required ground for the line.

Grounding both ends with a low impedance ground is good for lightning strike protection, but bad in a geomagnetic storm. Ungrounded is bad for line charging and lightning protection. UTP network cable is ungrounded at both ends and are subject to high voltage charging in short lengths.

The elevated lines between buildings are rarely protected from a build up of a static charge as routers and bridges were not built with this in mind. On the physical layer, both ends of the wire are terminated into an isolation transformer with no discharge path to ground. This is an installation design fault against the guy that designed the installation. Lightning protection is often a gas discharge tube for a lower breakdown voltage. A high current discharge through a protection device can produce a relatively high ESD pulse through the transformer into the tranciever chip resulting in corrupt data to failures. A link between buildings must include a bleed discharge path to prevent the build up of voltage on the wire, or a shielded wire with grounded shield should be used.

Engineers design systems. A good technician can make them work.

Comment Time to apply science (Score 4, Informative) 78

Time to apply science to the problem. What is known, what values are involved, and what breaks down.

Long distance transmission lines have two problems when there is a relatively high atmospheric current. They are long conductors feeding transformers that are not designed to shunt large components of DC resulting in core saturation and high current. This is measurable. The first effect noticed was by the railroad when telegraph relays activated and sometimes burned out.

The voltage induced current has two components. 1 Some current was due to the current directly into the long wire. 2 Some current was due to ground potential changing due to high current in the ground.

How to protect? For ground potential issues, simple pairs of wires provide high common mode rejection. This is common with telephone circuits as protection from induced hum and noise from a noisy electrical environment. Overvoltage protection in the form of lightning arresters is the second protection. Most phone loops are relatively short reducing the ground voltage gradient problem to non existant levels. Long distance hops are by Microwave Relay or Fiber Optic, both providing protection from ground gradients and long pick up paths.

Shrink the scale to inside a home by comparison. All internal house wireing is orders of magnatude shorter than transmission lines, CATV, and phone lines. Small DC capible antennas result in very low current if exposed. The home is generally protected by gutters on the eves, mildly conductive building materials such as wood, brick, etc that are not insulated to very low leakage at high voltages such as the insulatin on transmission lines. Net result is the very small currents are shunted by the building itself. Go up on the roof during a geo storm and see if you have any static electricity issues. Probably not.

For homeowners, this is a non issue due to the lack of an effective gathering surface properly insulated to collect enough current to cause any damage. The collector is too small and the leakage path to ground is too high.

I was stuck on Comcast when I upgraded from Dialup. Due to the games with non working services, I jumped ship as soon as Qwest offered DSL. Skype, VOIP via SIP, Google Voice/Talk, etc all working fine. I feel for those without the option. Comcast has been trying to win me back, but I'll take the slower DSL speed for everything working properly anyday.

Comment Re:No. (Score 3, Interesting) 502

Many of the earlier SB cards were known for a fixed clock, regardless of what the software was set for. This limited clock rate was the issue of many complaints of those looking for full 20-20K without artifacts. Once this reputation was cast, the line was considered as consumer grade and not better. Same applied to bit depth. The driver would accept many settings beyond the 16 bit DAC. Other cards had higher clocks and bits, and testing for the card performance showed the true limits.

Link below shows some of the real testing on this card beyond just golden ears. Look at the frequency output of noise and note what is NOT reproduced. Then scroll down a look at the extended frequency response of the cards in the test. SB hit a wall way before the competition.

Comment Discrete? Yes. Creative? Not so much. (Score 1) 502

Now admittedly, I'm a bit bitter about a problem that's not really Creative's fault. I bought an Audigy 2 ZS for my laptop using PC Card...and then the next wave of laptops only came with an Expresscard slot. So, I ponied up again for an X-Fi card that fit the Expresscard slot...and then laptops stopped coming with those. Now I fully admit that Creative isn't to blame for that, but it is sad just the same. However, I digress.

I use my onboard audio for nearly all of my listening needs. My internal speakers are utter crap (I think one is blown, actually), and thus, even if Creative added all the super-duper offboard processing in the world, it wouldn't sound any better than what those speakers can pump. Adding a nice set of Sennheiser or Denon headphones, I can start to hear some of the MP3 sizzle in the 128kbps MP3s, and a handful of 192's, depending on the song and the encoder and settings used. Even playing video games, the difference between 'Good Enough' and 'X-Fi Good' never comes into play, because it's the nuts-and-bolts of the big picture that will make or break it in either direction - if the sound effects and musical score is good, the miniscule difference an audio chipset will make has nothing to do with it. If they're crap, a ZxR processor isn't going to change anything.

That being said, I still use offboard audio hardware on a regular basis. I use my Rane SL3 to DJ with Serato. Even if it wasn't a de facto hardware dongle to unlock the Serato software, there's no motherboard chipset that supports 2ms latency from end-to-end of the audio path. In other words, my SL3 can reliably take an audio signal from my turntable, translate it into speed and directional data, and send MP3 audio back out, in 2ms. Creative doesn't make hardware like that. The story is pretty similar for my Audio6 (which I use for Traktor) and my Connectiv (which I used to use for Torq and Deckadance, though it required closer to 5ms latency to be stable). I have a MobilePre USB that I use occasionally for XLR and 1/4" recording. These are niche products for niche purposes, but the fact that your local Guitar Center sells a range of these kinds of interfaces demonstrates that there's indeed a market for discrete audio hardware. Creative just doesn't make it.

Comment D/A is good enoug, but.. (Score 1) 502

Onboard D/A for WAV, MP3, Movies, etc are generally good enough if the noise level is low enough. The biggest difference is in the on board synth. Playing games uses MIDI and the sound card produces the sounds. There are 2 versions. Hardware and software.

Hardware had an on board synth. It can be as simple as an 8 bit video game or as complex as full wavetable sampled sounds. An onboard hardware synth will sound the same on Linux or Windows. If the wavetable synth is XG compatible or similar, the sound is great. If a cheap synth is used it will sound like a casio entry level keyboard or 8 bit videogame.

Some cards use soft synth's with soundfonts. These can be very good sounding with inexpensive hardware as the synth runs in the OS and just sends the bitstream to the card for repoduction. This uses some system resources and requires installing the proper driver to include the synth and soundfont. This can mean great game sound in WIndows, but no sound or missing sound in Linux for games, unless you load a soft synth on Linux, install a soundfont, and enable it through Jack. While the combo does sound great, it is a resource drain.

Now, which is better? Mixed bag here. Some on board sound come in either variety. Same with add on boards.

Comment Minix on Atari ST (Score 3, Interesting) 136

I ran Minix for a year or more on my Atari ST - having a UNIX-like operating system on a machine I could have at home was a truly awesome thing. Tanenbaum's work is fascinating, useful and will be around for a good while...which is more or less the definition of "successful" in academic circles.

The debates with Linus were interesting - but I always felt that they were arguing at cross-purposes. Linus wanted a quick implementation of something indistinguishable from "real UNIX" - Tanenbaum wanted something beautiful and elegant. Both got what they wanted - there was (and continues to be) no reason why they can't both continue to exist and be useful.

Tanenbaum's statement that the computer would mostly be running one program at a time was clearly unreasonable for a PC - but think about phones or embedded controllers like BeagleBone and Raspberry Pi? Perhaps Minix is a better solution in those kinds of applications?

Comment Re:And, probaly, nothing of value was lost. (Score 3) 174

I for one had never even heard of these products, and I don't think I've ever encountered a web site using it. All I see is Google Maps when sites need to do something with mapping.

Well, duh. MapPoint and S&T was a plastic-disc software title, intended for end users to do stuff without an internet connection. See kids, in the days between the joys of attempting to re-fold a paper map and always-on, always-connected internet streamed maps, companies got all the street information together and sold a software release in a perpetual licensing format. People could then take their laptops and a serial (later USB and/or Bluetooth) GPS add-on and navigate with a laptop, without worrying about data plans, cellular outages, or getting stuck on a necessary phone call that brought into question one's allegiance to accurate navigation.

In the case of MapPoint, routes and distances were mass queried and used in tandem with Access and Excel to make geographical and topological data useful in a business context.

Websites are going to use Google maps (or yahoo/mapquest/bing, to a much lesser extent) because their APIs allow embedded maps nice and easily. For folks who need offline information, Google Maps was never intended to fill that space. Now, it seems, Delorme is the sole holdout for plastic disc mapping software.

Comment Re:Dang. What's next, Encarta? (Score 1) 174

Annoyingly, it's not just Encarta. It's seemingly any offline reference title. Grolier's is paywalled to oblivion, Britannica gives the first two paragraphs, Simon & Schuster haven't sold a reference app in years, and Wikipedia is, well, Wikipedia.

Now yes, the internet is how we get data around fastest, and even CDs were a de facto subscription since you'd buy a copy every year or two to stay current. I get that. Where plastic disc media had some usefulness to it was that, for K-12 schooling, it was easier to cite them as one would cite a traditional printed volume. Additionally, even if not the most bleeding edge information, most information contained therein would remain relatively consistent from year to year (especially ones on historical matters; technological matters, less so for obvious reasons). It also provided a baseline with which to compare other sources. If Encarta and Wikipedia disagreed, it'd pose the question of 'why'. Was there some sort of major breakthrough that allows Wikipedia to show its strengths as being an up-to-the-minute, crowdsourced reference, or is the Wikipedia article amidst an edit war? At least with Encarta, there's some semblance of "information freeze" where it's accurate to the point where the disc was pressed, and can be relied upon as such.

Sending reference works "to the cloud" makes sense, until companies paywall the whole thing, you don't know what you're really getting when you fork over your Mastercard, and it causes people like me to wax nostalgic for the plastic disc for well-written, relatively unbiased descriptions of WWII battles.

I second that on the courts. I had to drop off a document for a child case. I stopped at the metal detector and told security I was here to drop of a document, not visit offices, so I had not emptied my pockets. Please call the office of ... to come pick up the document. They objected. I said they can scan the manilla envelope. They complied. I made it clear I had no intention of wasting time for a drop off. It would be much faster for them to step out of the office and accept the delivery.
