Comment Re:Efficient? (Score 1) 176

The average kwh cost in the US is about twelve cents, or $0.90 to $1.20 to go 25 miles.

PG&E has standard rate plans that vary from 11c/kWh (which is so little that you can't afford a refrigerator) to 30c/kWh. There are also special plans (time- and season-driven); one of them is specifically intended for charging EVs. In that plan, IIRC, the rate is about 5 c/kWh - but that is at night only. I do not recall what is the rate during the day. Utilities hide the actual rate tables. PG&E has a convenient calculator. I tried it with Tesla S60 and 60 miles per day. I got about $150/mo on plan EV-A.

60 miles per day * 30 = 1800 miles per month. If we convert this to a gas car, $150 pays for about 42 gallons of gas. This results in efficiency of 42.85 mpg. This not something to write home about. My own Prius does 52 mpg on flat land, and 45 mpg if you add climbing of the surrounding hills. If these calculations are correct, it is not efficient to use an EV even if you got it for free. At best it equals the hybrid that costs a third of the price of the EV.

I'm not sure I understand their math. A Tesla 60 gets at least 3 miles per kWh (http://www.teslamotors.com/goelectric#range), so your 60 mile day would take about 20 kWh. At 5 cents per kWh, that is $1/day, so about $30/month. To get a cost of $150/month would take electricity at $.25/kWh. At $.05/kWh, you end up getting more than 200 miles/gallon equivalent, and that's if gas is $3.57/gal. Around here (Bay area) it's closer to $3.80. Like I said, the math is squirrelly.

Comment Re:Print shops? (Score 1) 166

So if I set up a print shop that prints and sells copies of recent bestsellers and sells them dirt cheap to bookstores that sell them at deep discounts to consumer's that's a misdemeanor? How about if I download copies of the latest movie releases, burn them to DVDs and ship them all over Europe?

Then you would no longer be a private citizen but would be engaging in business. I think that almost everyone agrees that anyone who does that for commercial gain should have the book thrown at them.

Better not copy "Lord of the Rings" then...

Comment Re:Ah, the memories! And lessons, too. (Score 1) 305

Ah, the memories! Here are some of the stories I've heard and or witnessed over the years.

  1. Buttons: Every couple years, IBM would hold an open house where anyone in the community could come in and get a tour of the facility (Kingston, NY). This was back in 1984, IIRC. PCs were just starting to make an impact at this time... big iron was king. We're talking about a huge raised-floor area with multiple mainframes, storage, tape drives... MANY millions of dollars per system. A few hundred users on a system was quite an accomplishment back then and these boxes could handle a thousand users. We were also in the midst of a huge test effort of the next release of VM/SP. I had come in that Sunday afternoon to get several tests done (death marches are no fun). All of a sudden the mainframe I was on crashed. Hard. I'd grown accustomed to this as we were at a point where we were "eating our own dog food"; the production system was running the latest build of the OS. But, an hour later and it was STILL down. Apparently, a tour guide had led a group to one of the operator consoles and a child could not resist pressing buttons. Back in those days, booting a mainframe meant "re-IPL" Initial Program Load. Unless the computer was REALLY messed up and wouldn't boot. Only then would someone re-IML the system. Initial Microcode Load. Guess which button the kid pressed? It left the system in such a wonky state that it had to be reloaded from tape. All the development work of that weekend was lost and had to be recreated and rebuilt. (It was a weekend and backups were only done on weekday nights.) It took us a week to get things back to normal.

Hey, I have a similar story from when I was working at Dartmouth College in the mid-80's. I was on third shift with two other guys, one who knew what he was doing, and one who was, uh, not fully technology-enabled.

For some reason, one night the latter person thought it would be a good idea to clean out the cabinet of our Honeywell mainframe. With a broom. A long-handled push broom.

This was on a weekend, when we normally do a full backup (onto good old 9-track tapes), reboot the system into protected mode, verify the system integrity, and go into multi-user mode. Well, we finished the backups, and tried to reboot. Nothing was working, and the diagnostics were wonky and pretty uninformative, and we (the useful co-worker and I) spent an hour or so trying to debug what was going on. It wasn't until we asked the third guy about the machine that he mentioned his cleaning. The boot switches for the IPL were on the door, and when he was in there cleaning, the broom handle toggled several of them, leaving the machine in its unusual state.

Needless to say, we asked him to avoid cleaning mainframes with brooms in the future.

FUSCHIA I really hope that was intentional.

Of course it was... it was a setup for another poster to come along and elevate the irony level via a similarly-constructed officious-seeming announcement in order to enhance the joke and provide, hopefully, additional chuckles among the fine readers of slashdot. Instead, by observing my typo, and failing to take the opportunity to craft a joke out of it in the same vein... why that's a complete waste of a setup. Can you help a brother out and at least continue the joke when the effort of a setup has been made?

This thread, however, is a fine example of depth-first self-flamage. For those of you who were in one of the schools that failed to properly teach computer science, observe and be edified.

Comment Re:TiVo invented timeshifting? (Score 1) 490

Yeah time-shifting is nothing new. It has existed ever since the Sony Umatic VCR released circa 1969. That VCR was too expensive, so Sony went back and created the Betamax (anc JVC copied it to create VHS) in 1975. DVR is not even the first digital recording method - that was miniDV and Digital VHS in the early 1990s. ----- People have been time-shifting for decades. All the DVR did was replace the magnetic tape storage with magnetic disk storage. Nothing revolutionary... it was an evolutionary change.

On the contrary! Using a disk to store data is completely revolutionary!


Sorry about that... couldn't help myself.

Comment Re:"No flight ceiling" (Score 1) 276

I'm not an engineer so I can't comment on the operating ceiling of the the thing but speaking as a former private pilot, 9,150 meters (FL 28, roughly) is already well above the point where the pilot-in-command would be allowed to operate without supplemental oxygen.In fact, up that high you'd be messing with the three-holer transport jets and would probably need a pretty high-quality heated flight suit.

Erm, FL 280, right?

Comment Re:It's "going to the mat." The mat. (Score 1) 102

The actual history of "going to the mattresses" comes from the Joey Gallo and the war between him and the Profaci family. The term appeared in the headlines in the early 60's in the headlines in New York newspapers.

Info: http://en.wikipedia.org/wiki/Joe_Gallo#Gallo-Profaci_war http://tomfolsom.com/blog/

Also, this term appeared in the book "The Valachi Papers". From what I recall, it is supposed to mean getting serious about a mob war, where the various mob soldiers would live in rented houses/apartments, sleeping on mattresses, for the duration of the war.

Super-Earths Discovered Orbiting Nearby, Sun-Like Star 242

likuidkewl writes "Two super-earths, 5 and 7.5 times the size of our home, were found to be orbiting 61 Virginis a mere 28 light years away. 'These detections indicate that low-mass planets are quite common around nearby stars. The discovery of potentially habitable nearby worlds may be just a few years away,' said Steven Vogt, a professor of astronomy and astrophysics at UCSC. Among hundreds of our nearest stellar neighbors, 61 Vir stands out as being the most nearly similar to the Sun in terms of age, mass, and other essential properties."
