Might be a bit off-topic, but when the system gets (for example) 5 answers from 5 different computers, how do they make sure that the program/computer that reads and verifies those 5 answers is correct and fault tolerant?
Don't know and don't know if that situation ever occurred. Any Shuttle computer systems experts out there?
There are good practical reasons for writing the same program in different languages. (1) People often make the same mistakes in the same language, because they are often taught/trained in similar fashions. (2) Different programming languages have different issues and failure modes.
I'm not an expert, but I worked as an undergraduate research assistant on a project way (way) back in college (1985-87) for a professor on a NASA contract to study issues related to N-version fault tolerance - like used on the Shuttle, where several computers solve the same problems and vote on the answers. One problem (if I remember correctly) was that the different programs, written by different people, in the same, or same type of, language often failed on the same or similar edge cases.
The experiment was to implement the same solution to a problem using much different languages. In this case, Pascal and Prolog. The "gold" Pascal routine was already written and my task was to write the corresponding "gold" routine in Prolog. [ I also did work for a related study in the automatic analysis (and execution) of abstract data types in LISP.] I graduated before the experiment was run, but found the idea as least plausible.
Note that I might be remembering some of this incorrectly as it was a while ago and I was only an undergrad. (They wanted a graduate student, but I was the only one with LISP and Prolog experience... And $9.50/hour wasn't bad for 1985.)
Sarah Palin was a successull governor of a large state for years before getting picked to be a VP candidate, and the media skewered her.
you have to admit she was a total joke and had it coming.
In addition, while Alaska may be a large state in terms of *area*, it's ranked 47th in population with fewer people (735,132) than Rhode Island (44th w/ 1,051,511) and Delaware (46th w/ 925,749). Seriously, Fairfax County, Virginia has more people (1,118,602). I guess "large" is a matter of perspective (hopefully GP's girlfriend will understand.)
If the ice was covering the globe, you'd have a point. But saying that my basement is cold doesn't prove that my whole house is.
This is/. so I imagine you meant your parent's basement. And it being cold means you're not going to get a girl naked there. (Pray for a warming trend Grasshopper.)
...and that kid barred from practicing medicine or research EVER. Getting caught cheating in a professional field where people's lives are at state should be a capitol offense.
Or just give him AIDS and let him decide if he wants to fuck with the research again.
[Sorry, that was really mean.]
I just made that up and pronounce it to be art.
You are allowed to either appreciate it's beauty or admit that you hate all art.
Any -1 mods are merely people who don't understand art and whose opinion on art should therefore be ignored.
I'm reminded of the scene in L.A. Story in which Harris (Steve Martin) is admiring and remarking on a painting hanging in the museum:
Harris: I like the relationships. I mean, each character has his own story. The puppy is a bit too much, but you have to over look things like that in these kinds of paintings. The way he's *holding* her... it's almost... filthy. I mean, he's about to kiss her and she's pulling away. The way the leg's sort of smashed up against her... Phew... Look how he's painted the blouse sort of translucent. You can just make out her breasts underneath and it's sort of touching him about here. It's really... pretty torrid, don't you think? Then of course you have the onlookers peeking at them from behind the doorway like they're all shocked. They wish. Yeah, I must admit, when I see a painting like this, I get emotionally... erect.
[The camera pulls back and the painting is revealed to be of a large red rectangle.]
If efficiency was cool, Linux would have been developed in the 1960s...
Of course, you realize that Unix development started in the mid 1960s.
The history of Unix dates back to the mid-1960s when the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric were developing an experimental time sharing operating system called Multics for the GE-645 mainframe.... On this PDP-7, in 1969, a team of Bell Labs researchers led by Thompson and Ritchie, including Rudd Canaday, developed a hierarchical file system, the concepts of computer processes and device files, a command-line interpreter, and some small utility programs.
Thanks and I'm trying to not sound like a broken record. Sue and I were an improbable couple that were together simply because we wanted to be together more than we wanted anything else. I also mention her because there seems to be so many instances where I hope someone could have something like what we had and/or would open their eyes, hearts and minds to the possibilities out there - especially if they'd let go of, or ignore, all the crap that gets in the way.
Sue lost a few friends because they couldn't wrap their heads around her dating someone 19 years younger, but our relationship lasted longer (or would have, had she lived) than all of theirs. As for me, ya my heart is crushed but I'd do it all over again, even if I knew, and couldn't change, the outcome. I'd rather have 5 minutes with Sue than a lifetime w/o her. As it turns out, I'm lucky and cursed enough to get both - 20 years with her and 1/2 a lifetime without...
From the people I have talked to, it is not an issue of not being open, it is an issue of how people approach them. Lots of guys wanting arm candy or quick sex, but the number who talk to them like people and show actual relationship interest really drops off. In other words, people stop considering them.
I can understand that. I think it's stupid, but I can see it being true - for both men and women. I guess my original comment can then apply to both the model and prospective suitors.
Personally, I like women who are smart, interesting, dynamic, direct and independent. Being easy on the eyes is just a bonus. I was very lucky meeting my wife, Sue, (who died in 2006) but being *that* lucky again is improbable... (Someday, I might start dating again and find out.)
They mainly have coal plants which take hours to take off / bring online. A few days of good wind and low demand meant there was nowhere for the electric to go.
Water is released from the upper reservoir during periods of high demand and is used to generate electricity. What makes this different from other hydroelectric dams is that during times of low demand, power is taken from coal, nuclear, and other power plants and is used to pump water from the lower to the upper reservoir. Although this plant uses more power than it generates, it allows these other plants to operate at close to peak efficiency for an overall cost savings.
Why did your friend wait so long to let you know that he was ok?
We only talk a few times a year and (I imagine) he had closer people and family to talk to and other more urgent things to do. I had sent him email, but he had been unable to check it. Shit happens, we get by...
Why did they announce separate disc / streaming services (Quickster), and then immediately backtrack?
I believe they considered splitting the company, expecting (allowing?) the disc company (or business unit) to die off w/o impacting shares of the streaming company/unit. This would have also allowed people to tailor their investments. Perhaps not a good technical idea, but I can see the business merits, especially if you expect disc subscriptions to die off in favor of streaming.
That's the problem with identifying an A player - defining what is really valuable to the company.
In addition, different things (skills, experience, stamina, etc...) can be more/less valuable at different times or in different situations. Having a good mix of people helps fill any voids in the team and provides some overlap for when things get difficult.
Maybe you could just ask people why they're no longer "A players" (which is a crap word in itself) or if they're going through a rough patch in the life?
I got fired from a job about a week after 9/11. I was being unusually bitchy and short-tempered to my co-workers and (new) manager. I didn't really know why (at the time) and no one bothered to ask; they just fired me. A few days later, I got a call from my friend who worked in one of the twin towers to say he was okay. My mood greatly improved, but I was still unemployed.
Oddly enough, many actually are caught in a dating quagmire. There are certain tiers in the modeling world, if you are above a certain level (too exotic for non-elites) but below the level where you are integrated with the elite culture, they kinda end up in a bit of a dateless limbo that only really ends if their career picks up or fails.
If true, then I imagine things might be different for them if they (a) stopped caring about what other people think of who they choose to date and (b) opened their eyes, hearts and minds to a wider range of people to date. In reality, one never knows exactly who that perfect person is for you and it may be someone unexpected or otherwise unconsidered. (Unless, of course, you're just dating someone to enhance your own career/status.)
So, it seems to boil down to a test of compute power on data sets small enough to fit in memory rather than an effective test of relational query processing, though they did use relational queries as their base testing model.
Or... Just because you can do something, doesn't mean you should.
Slashdot Mirror
You really think 3D printing needs less human operators than injection molding?
My understanding is that many (most?) molded parts still need manual trimming. Is this true and do printed parts needs the same "finishing"?
[ Also, editors, title should be "flies *with* printed parts" not "*on*". ]

Most of us don't admit to being time travelers.
Technically, we're all time travelers - all of us, forever going forward in time.

Does this make what SETI is looking for pointless? Should they instead be looking for lasers if they work better for communication.
No. SETI should be looking for sharks - duh.

That requires you to pump water uphill, and HI has very little fresh water.
Does it have to be fresh water, 'cause I think HI has a bunch of other water handy.
They mainly have coal plants which take hours to take off / bring online. A few days of good wind and low demand meant there was nowhere for the electric to go.
They should consider doing something like the Bath County Pumped Storage Station in Virginia where:
Water is released from the upper reservoir during periods of high demand and is used to generate electricity. What makes this different from other hydroelectric dams is that during times of low demand, power is taken from coal, nuclear, and other power plants and is used to pump water from the lower to the upper reservoir.
