My impression is that Apple II/VisiCalc were used by small/personal business and Lotus 123 was for big corporations/industry. But I might be wrong since I wasn't even born on that period.
I don't get it. A legally binding contract was signed before they took on the job, right? Doesn't that offer legal protection?
idk, I don't really see any reason that it is better to give vermonters jobs at 10% above the median wage for the area than chinese people or wherever these jobs are going. I do think corporations have certain obligations, like not polluting, following the law, etc... but keeping jobs.. that is a hard one for me to swallow. I think redundancy in manufacturing is inevitable and good (in the long run) as everything goes toward automation; I certainly would not want corporations to be forced to hire people to do what robots can do.

Maybe I am taking a leap here. It is undeniable VT is anti-business (high taxes, nearly impossible to build, no billboards, high minimum wage) but maybe this exact same plant would be leaving Florida or Texas as well.
This isn't a deeper look. It's a shallower look. Didn't Musk say that the estimated range is dependent on speed, and that Broder sped illegally fast for part of the trip? There are other factors, as well.

There may well be something to say about Tesla's estimations being off, but this isn't it.
Agree entirely with this.. often i take 30% up front, 30% when prototyped, and final 40% payment upon delivery
First of all let me make it clear that I'm not against all "magic", but let me address this:

> But isn't this the whole point of a framework? That stuff gets done for you so you don't have to write everything from the ground up?

There is a vast difference between a framework that does stuff for you when you explicitly ask it to, and where what happens is fairly transparent, and a framework that does stuff for you because of code that without knowledge of the framework looks fairly "inert".

E.g. calling methods to define attributes and attribute-accessors on a class that maps to a database is not magic (though depending on how extensive, you might argue parts of what a specific ORM does in that case is): The code makes it plain that something will happen, and unless the naming of the method is atrocious, a developer will have a good shot at guessing roughly what from the code itself. You can make a framework that does a lot for a developer while still being explicit like this.

Automatically defining attributes pulled from the database based just on including a module, or inheritance, on the other hand, is well into "magic" territory: Not only might it not be clear it's going to be pulling stuff from the database and define lots of attributes for you, you don't know what it will define at all without looking at a schema that might not even be available together with the code, and that might change independent of the code.

It's not an either-or, but a sliding scale, and what is magic to some will be plain and obvious to others (the Arthur C. Clarke quote springs to mind). E.g. "everyone" who knows Active Record will know at least the basics of what Active Record will do to your class, and so won't be surprised by most of the method that to another seemingly magically materialize on it.

The trade-off is how far you go before the surprises to your target audience become too many.
No it's not. "Intelligent routing" means giving each server exactly as many requests as it can handle, and no more. If your servers can handle 3 requests each, using intelligent routing to make sure they never get more than 3 will blow the latency of the random method out of the water.
FWIW, if the House were truly proportional then Democrats would control it as well.
What stings a little more is that the webserver at python.co.uk is running Debian[1], which contains some version of Python by default (even in the minimal install).

I hope our trademark office has the sense to reject this.

What the article is explaining can be summarized in this chart: http://i.imgur.com/mNcGdfS.png

But I think this is incorrect:

> In nearly every case, the Tesla gets about 20% fewer miles out of each charge than it estimated.

Musk and Broder 'agree' that the vehicle's actual range was greater than it estimated. Musk's wrote,

> Then he bizarrely states that the screen showed “Est. remaining range: 32 miles” and the car traveled “51 miles," contradicting his own statement... The car actually did an admirable job exceeding its projected range.

As an aside, please disable Tynt on your blog.
I wonder how well they can actually get farmers online. I grew up with lots [of farmers], and most of them would hate this only because it's on the internet. Most farmers are not that [internet] tech savvy. Also, the pricing structure seems like a farmer would look at this and be like "Uhh..? Why?" I wish them luck, but I grew up with that culture and still know a lot of them, and I just can't see this taking off by the way their mindset is.
Not all batteries - but lithium batteries in general are known for greatly reduced performance in the cold. Take your camera out in the winter some time and you'll find that it'll drain several times faster than normal.

I read a recent interview with a well-known landscape photographer who shoots in the Arctic - he carries a whole bandolier of batteries, kept close to his chest at all times to keep them warm. Apparently in the extreme Arctic cold the batteries are reduced to literally a few dozen shots before dying.

"Sue us and your license is revoked" is quite a reasonable provision, IMHO.

Edit: if you're going to down-vote, at least read my clarification below.
There are only two questions to answer here:

1. Did the reviewer take off on the final leg with insufficient charge at the advice of Tesla, or against the advice of Tesla? This caused the towing incident that created a sensational news story. Both sides disagree. There is probably no audio recording (which is illegal in many Northeast states without two party consent) so this is an area where one side can lie with reasonable impunity. One side is clearly lying, so it's a shameful situation. But that's not really as important as #2:

2. Does the car lose miles overnight in cold weather, or driving in cold weather? The answer here is unequivocally yes, and this is the story that Tesla doesn't want told, and hopes to distract from. It means you can't take it on a long ski trip deep into the mountains, or leave it in the airport an extra day without an annoying long recharge cycle. This can't be solved by charging overnight in some cases, as on long trips you still need to drive through the cold, so the range can decrease as one drives. The people who buy Teslas like to ski, like to fly, and don't want to wait two to six hours hours for a full recharge when a supercharger is not around.

The blog post doesn't really rebut #2, though it does try to distract and smear credibility with various nits which technically may be correct but are irrelevant to the basic questions. Classic courtroom defense strategy.
Slightly related is this documentary, Skid Row (http://www.imdb.com/title/tt0795381/), in which a guy goes and lives in Skid Row in Los Angeles for 9 days. It's free to watch on hulu and probably other video sites.
I am wondering what kind of valuation this company had got. To raise that amount of money I expect at least $12M post-money valuation (and still they have sold about 50% of the company for a seed round).
So, the question is what kind of mind-blowing traction they had?
These are excessively detailed numbers with very little context. What is the code doing? What's the performance of the equivalent implementation in another language (I'd be most interested in a typed language like Java)?

I realize you probably have more context in your head but for everyone else the body of the post adds very little to the title.

The goal is for every American citizen's vote for President to count for exactly as much as any other citizen's. That means, yes, the person who gets the most votes wins. How else can it work?

I'd encourage you to take a look at the National Popular Vote's site, especially http://www.nationalpopularvote.com/pages/answers.php . They've put quite a bit of thought into it.

edit: On second thought I was eating a restaurant when their televisions turned black and the screen came up with a pay your bill now notice. Every screen in the restaurant. So I guess maybe this is the tactic.
My suspicion is that this is being done because it's international. If Fitness SF is as I suspect in San Francisco while the developer is in Europe, collections will be a real headache. Sue? Sure, probably where you are, probably win. Then collect from the European presence of a California fitness club. I see a potential disconnect.

Sue in California? How much is THAT going to cost someone based in Europe?

And really, what recourse does Fitness SF have either? If they sue him, maybe they win. Maybe that makes it hard for him to come to the USA. Is that a problem for him? Can they legitimately go after him vs his company (and vice versa). It's a no-win situation all around.

I'd say that the big lesson to be learned from this is that international customers pay up-front and with a deposit if you're going to allow things that increase the price (e.g. rush changes). For most things there's not usually a good reason to add the expense and complication of 12-hour time differences and international borders unless you're planning up front to make legal recourse difficult.

Agreed. They were doing CDS deals. Every bank I've worked at has their models in COM assemblies that can be consumed by Excel. Excel lets the traders value their instruments using the models. The inputs may have been copy-paste but I'd be hard pressed to believe that the risk numbers were generated by hand in Excel unless this was some very exotic instrument which I don't think it was.

Risk numbers aren't generated by Excel but an automated process that uses the same assemblies.

I am not thrilled about this development. It's not that I think this scientist isn't being clever or useful. The real problem is that not all science is sexy enough to draw funding this way. More specifically, a lot of really important science does not make for a great elevator pitch.

Perhaps I'm oversimplifying by seeing the pot of potential science funding as inherently limited. However, I fear that if we give the public the idea that science should be funded this way, then we deemphasize basic science, making it even harder for groundbreaking work to get funded.
While the term estimation is by definition not exact, I challenge anyone to find a car on sale that has 100% accurate estimation. It's just not possible.

The point, imho, is that the press is always trying to find a story also where there isn't. Sad for them, this time there's the hard data to support Tesla's facts.
At Zaarly, we use next-day ACH to pay out our sellers. It's a total game-changer. Our sellers do business with buyers, and they have the funds in their bank account the following business day.

> In your simulation, you are only taking into account predator1, i.e. the predator that hatches at even years.

1. No, not even years necessarily, but any scenario in which cicadas and predators hatch out in synchrony, regardless of the numbering of the years (as long as both cicadas and predators have the same year number applied).

2. Did you miss that I tried adding one more loop that tested all the relationships between cicadas and predators WRT year differential, and that shows only a tiny advantage for prime-numbered years? The size of the effect being discussed only works if predators and cicadas hatch out in synchrony, so my having set both to zero ends up emphasizing this specific case to a perhaps absurd degree. If it weren't for the fact that natural selection tends to amplify small fitness advantages, this relatively small effect might not be be worth discussing.

> The primary reason why cicada all hatch together is because then the predators cannot catch them all because there are simply too many cicada.

Yes, true, but this doesn't address the timing of the synchronous hatch-out. Why 13 and 17 years, and no other cycles in nature? My paper only addresses the timing of the hatch-out, not the fact of it.

> you can't a priori assume that predators that share a prime factor are always synchronized with the cicada as you have done here.

But I don't do that. My simulation addresses the case in which cicadas and predators hatch out in synchrony (advantage goes to the cicada), versus times when they don't (no advantage or disadvantage). It's not an assumption, it addresses the fact that cicadas and predators sometimes do hatch out in synchrony. There is no "always" assumption at work, only that, when there is a synchronous hatch-out, this works to the advantage of prime-numbered reproduction cycles. Other year relationships between cicadas and predators show no advantage or disadvantage.

It's true that my simulation greatly exaggerates the effect, since such a synchronous hatch-out is rare in nature. But I already discussed why designing as full-on natural selection simulation would probably produce nothing more than an exhibition of confirmation bias.

The effect being discussed is real, it is much smaller than my simulation would lead one to believe, but natural selection often amplifies small differences in fitness.
Shouldn’t the estimation be conservative, not generous? Especially in this case?

> What I am saying is that in the "rural bias" link they refer to the Senate as "overrepresenting rural citizens" and the point I'm making is that the Senate is not about representing citizens, it's about representing states. And it's meant to balance the House, which is about representing citizens.

Why do we need a balance against representing citizens? I think the only reason for this is that money from the Federal gov't often goes to States and not directly to the people.
Other reviewers may not be under the same influences from incumbent auto manufacturers or the oil industry for various reasons. They almost certainly also have less readership than the NYT so what they say matters less.

There may be speculation about certain facts in the case but there is absolutely no speculation as to the fact that this and every other corporate journalist is under systemic influence. In any other industry it would be plainly obvious that employees understand not to insult, aggrieve or otherwise harm their employers customers, especially by way of prominent national media. Somehow everyone manages to convince themselves that what is obvious is no longer so when it comes to journalists and the MSM.

http://linux.die.net/man/2/cacheflush

There are other CPU architectures than the Nehalem.

The Nehalem's IO hub connects to the caches, not to memory, via the QPI. I/O sees the data as the caches see it. Most architectures, historically, have the IO systems talking to main memory or a memory controller independent of the CPU. Not waiting for memory to be consistent before firing off a DMA was a great way to get "interesting" visual effects.

We called that process "flushing the cache".
"Didn't Musk say that the estimated range is dependent on speed"

Did he? Because from this figure, it appears the estimated range is NOT dependent on speed (as, of course, it should be). Notice that the lines are extremely linear, with identical slopes throughout.

If he sped for part of the trip, why don't we see steeper slopes during those times?

So Broder "sped illegally fast." What does this even mean? The speed limit is 55 mph on most highways, but nobody goes at that speed. Can the Tesla range estimator not acknowledge speeds about 55 mpg?

The cost of rejecting yet another poorly conceived business plan by a marginal candidate is less than the potential loss of billions if the guy who comes up with THE NEXT BIG THING is too shy to apply to YC.
