Comment Re:Problem with egos really (Score 1) 525

The graphs show that this happened. Looking at the map of range over time, the most efficient leg of the trip was at this time, while the batteries were presumably warming up.

If the estimated range remaining is R and the distance traveled is L, then dR/dL= -1 under ideal conditions. Over most of the trip, dR/dL is about -1.25, presumably consistent with fast driving and heater use. On that one segment, dR/dL = -0.7, which means either rolling downhill with a tailwind or that the range estimation is wrong.

Comment no tape of the calls with Tesla (Score -1) 525

You can be smug and pretend you can read minds, or you can read the articles and think. Broder says that Tesla told him that the stated range was not right due to the cold and that the battery was more charged than that and would get him to his destination. Did they say this? There are no tapes, so no one knows. Did the car in fact go much longer than the range the computer said? YES IT DID. Did it make it to the charging station? Almost but not quite.

Which is more believable, that the author made something up because he hates electric cars, or that Tesla told him something qualitatively correct but quantitatively incorrect? Anyway, without tapes, it cannot ever be known.

Comment SDA/SDB are not permanent names (Score 1) 458

I think that TFS and you are wrong about using /dev/sda(b,c...)

With the old IDE buses, names like /dev/hda and /dev/hdb depended on the physical connection and were permanent, as long as you didn't move the disks around. Currently, the sda, sdb... names do not depend on the physical hardware and are not guaranteed to stay the same every boot.

Size and manufacturer is the only reasonable way of referring to the drives. Would serial number be better? (Clearly, in this case listing existing partitions would be better.)

Comment Re:Publish or Perish (Score 1) 67

> the way to make a name in academia is to overturn the status quo.

I don't think it's as simple as that. An unknown researcher can't fight the conventional wisdom merely by being right. A recognized rising star might fight the accepted view. Or the CW might be tottering and rotten and the critics ready to rally around the right attack from a newcomer who has nothing to lose by bucking the establishment.

Comment Re:1000Bq per WHAT? (Score 2) 210

The rest of the article refers to contamination levels in Bq/kg, which seems to be the standard unit for this. The level 1000 Bq/kg is not tremendously high, as it is only a few times larger than safe limits for human consumption of cesium-contaminated water (which hopefully are conservative). (And writers who don't know the difference between "rem" and "rem per hour" are even worse.)

Comment more hours != more accomplishments (Score 4, Insightful) 454

Dead on with your question "do they really get more done?"

What I have seen in graduate students is lots of inability to concentrate and make good decisions on top of exhaustion and insomnia. I have seen months spent going down the wrong track because of an inability to think clearly. I have seen late nights spent fixing things that were messed up due to tiredness. I have seen students who can't get anything done in the lab because they hate grad school and can't enjoy doing anything else because they feel that they should be in the lab.

Want proof? Look at how many graduate theses start with a 100-page literature review, covering material which is well known and not particularly important to the real research. The appropriate material would be 15 pages and lots of references. That review represents many months of wasted energy and probably lots of 80 hour weeks accomplishing nothing of value.

Comment Re:Not so good (Score 1) 66

All the people who travel and never look up except through the viewfinder of the camera can now stay home. All the people who clog museums taking photos of the art can now stay home. By all means let us devalue the trip of someone whose interest doesn't go much beyond, "Now I can say I went there." Make more room for those of us who are ready to open all our senses to new experiences and let our attention linger over details.

Comment Re:Honestly not that bad (Score 1) 646

It often works fine as long as you only use your computer the way that Lennart wants you to (single user at a desktop running Gnome). If you have different ideas, the setup can be difficult and poorly documented. It's very good at stopping flash from locking up the audio, which is the main reason I keep using it on some computers.

Comment "jerky" as a projection artifact (Score 1) 105

Often silent movies look "jerky" because of how they are shown ( http://en.wikipedia.org/wiki/Silent_film#Projection_speed ). In particular, video for TV has a fixed frame rate, and transferring the movies to a different frame rate while maintaining smooth action is not trivial (http://en.wikipedia.org/wiki/Telecine).

Comment Re:Crowdsourcing FAIL - crowds can be sourced. (Score 1) 121

"Some review spam is remarkably inept." Also note that paid reviewers don't review the same things that normal people review. A real person will review 15 restaurants all over a city in the course of a year or two. A paid reviewer will review 4 pet grooming shops and 5 auto bodywork places in one week. Check the histories...

Comment Power plant size? (Score 2) 318

What is the best estimate of the operating size of tokomak power plant? How many do we need to convert the US away from coal & gas power plants while switching to electric cars? What is the answer if we look at 100-year projections for population, energy usage patterns, and density? Will a tokamak-based power grid be more or less useful in parts of the world with different needs, like Europe, Japan, India, or China?
