"The seemingly random parking lots I'm traveling between are sites of a new nationwide network of fast battery charging stations for drivers of Tesla's Model S." If I am reading the article correctly, the journalist driver is trying out a trip between Supercharger stations, for which the mileage estimates on a Tesla as shipped from the factory would be quite relevant.

The article has a good discussion of the trade-offs between having a lot of charging stations and not having so many at the beginning of the electric car era. This paragraph especially caught my eye:

"Tesla won't offer any details about how much it costs to build and operate these Supercharger stations, but according to internal documents obtained by TechCrunch, they're an expensive effort, marketing or no. Each Supercharger station is estimated to cost between $100,000 and $175,000, and Tesla is picking up the entire tab — from installation to maintenance to the cost of providing the large amount of energy needed to charge their cars so quickly. Nicholas says Tesla is internalizing this cost and adding it into the price of the Model S, which can range from about $70,000 to more than $100,000."

Yes, that where I see this being most beneficial.
I was thinking the same. Why can't you hook it up to a running car and get some charge in the battery to get to the nearest charging station?
I think this is where crypto currencies really shine. They remove the gatekeeper for financial services. All their other benefits (and risks) are less significant.
I think Leap Motion is great, but I think that same kind of sensing can be achieved through lower tech ways, like a multi-color glove plus a webcam.

It is a cool idea and I hope they succeed, but I'm working on the low-tech LEAP idea and I'd like to see how far that can stack up to their more complex system.

"He foresees a greater variety of hybridizations combining oil, natural gas, electric batteries, hydrogen fuel cells and maybe some as yet undeveloped alternative fuel options."

Surely engines that combine multiple energy sources are more expensive and less efficient than engines that use a single source? My understanding of the current hybrids is that they exist because one energy source (petrol) can be quickly and easily replaced, whereas the other (electric battery) takes time to replace and isn't as easily available. Best I can tell, that makes hybrids a temporary solution to the lack of widely available better energy sources. Once most cars have settled on a non-petrol energy source, I can't see why hybrids would continue to exist.

I'd be so glad to own a laptop where the touch pad became unnecessary and got removed. I'm a laptop-only user, and the padding between the keys and the closer edge of the laptop is a source of pain for me, as it forces me to place my lower arm at the edge of the computer, which causes my lower forearm and carpus to hurt. A 15-inch laptop can be built with a keyboard that begins from the closest edge of the device's bottom, and the space between the screen joint and the end of the keyboard can be filled with... I don't know, a couple of large speakers and dedicated media buttons? A phone charging unit? A coffee holder. But such layout would definitely help my wrists and arms.

A backlight is something like 3 watts, a car stereo is consuming something like 10 watts. Running them for an hour is 13 watt hours.

A model S uses 237.3 watt hours per kilometer.

If you turn them completely off for an hour, you can go an extra 50 meters.
If you're going to turn down the brightness on the screen to save energy/fuel, you might as well throw your clothes out the window to reduce the weight. Every little difference helps, right? :)

You only have a couple of kilowatts of power output from a large alternator. So you would have to run the car for quite a long time to get much charge (I guess it wouldn't be so bad to get 10 miles of range that way though).
Nah, we never get the blondes :(
Hm, I wonder how quickly the sensors would be covered in random kbd crud.. Cool idea, but why not leverage a Leap Motion device somehow?
My local Chase branch has been calling and emailing me relentlessly, multiple times per week for the last four weeks or so, ostensibly because required "profile" information is missing on my business accounts.

I replied by email to ask what information they need. They won't give any specifics, but insist that I schedule time to meet in person.

I've had the same Chase accounts for many years, and my business is pretty mundane, so I assumed it was just overzealous cross-selling of services or investments that I don't need.

But according to this EFF article, maybe there's more to it?

The tech industry was male dominated up through the 1980s. Very few women graduated from technology oriented universities. It's not difficult to discern the roots of sexism, and the lingering effects in tech in general, and computing, specifically.

I don't know what music industry commentary you are looking at but sexism in hip hop is pretty widely commented on. What's the analogy you are going for? How might it excuse sexism in tech? I'm not getting it.

Can they follow an online tutorial? Sure. Could they find converting their cash to BTC with the proper safety measures in place too cumbersome a process to make the experiment worth their time and, if not careful, their money? Absolutely, and that doesn't make them idiots.

Some people really like tinkering with new tech and are willing to put up with a lot. Others have a low threshold of frustration and might not see it as appealing. This isn't about intelligence, but ease and convenience. And anyone that says with a straight face that setting up BTC for even the average MIT student is a simple endeavor is severely underestimating the complexity and risks involved, especially when the alternative is using the established and relatively risk-free system you've grown comfortable and intimately familiar with for years.
Part of understanding what the most efficient way to perform a task is, comes from understanding the optimizations which have already become commonplace.

What you say is true, but it's not either/or. Knowing how to implement something besides quicksort is important as well - the algorithms matter because they represent paths to efficiency. How can you judge what a good solution on SO even is unless you understand what you're looking at at more than a superficial level?

Hydrogen is a loss-leader put out there to buy Energy companies to buy a few more years of their incumbency and rent-seeking behaviour. It is just publicity and marketing. I am not a physicist, but I am pretty sure that the process of chopping up CH4 (methane; an already efficient source-fuel) and converting it to hydrogen to run in sub-optimal conditions in a small engine without any nationalized distribution method; is nothing more than posturing. Hydrogen is a relatively dangerous element and is pretty difficult to transport.

It IS the most abundant element in the Universe. Unfortunately, just not on Earth....
That's so sketch and dangerous.
So they left on a long trip with a 93% charge knowing that it was going to be close and fell short by 3 miles... why is this news or article worthy?

> I did not miss his fundamental point. I was making a different fundamental point about why I view virtually every meta-analysis out there to be even more suspect than regular research.

It certainly sounded like you missed it, but regardless: meta-analysis is well-aware of the selection issue. Dealing with that is half the point of meta-analytic techniques - p-curves, heterogeneity, funnel plots, the binomial test, trim-and-fill, etc. Publication bias is an issue which has been repeatedly quantified, and these techniques work reasonably well: when meta-analyses are compared to very large RCTs where selection issues are not a concern, the agreement is pretty good (confidence intervals are blown a bit more than they should be, but not horribly so). So you're either ignoring OP's very interesting points or you're tendentiously overrating an issue. Neither is a worthwhile comment.
They could probably double their resolution with an IR sensor under the keys, transparent elastomer, and IR-transparent plastic for keys. But they did mention sampling at 300Hz was an achievement so maybe they're running into some embedded issues.

> As a developer who's worked in games, embedded, and real-time situational awareness software (ex. air traffic control), my feeling is exactly the opposite.

I call availability bias: people who work on high performance niches feel everyone is underestimating the problem. People who work on low-performance niches wonder what's the big deal.

What I have personally observed is more like a fear of poor performance, coming from people who don't understand the problem like you do. So the team choose C++, which eventually leads to an unmaintainable, slow Big Ball of Mud. 'Cause as your AOS vs SOA example demonstrates, C++ doesn't magically make your code fast. Oops.

> That does not however obviate the necessity for a systems level language to provide the capacity for such optimization.

Agreed. Just two caveats: first, C++ is really a last resort, to be used when nothing else will do, not even C+Lua or similar combination. Even for high performance code, this language is way overused. Second, while we all use the high performance infrastructure you speak of, few of us get to write it.
> articles like this really annoy me, as they don't provide any meaningful substance

If you've thought about owning an electric vehicle, one of the first thoughts that pops into your head is "what happens if I run out of juice in the middle of nowhere?" Including questions like "How does the car behave? Does it just shut off?" to "How does AAA handle it?" to "How hard is it to get going again?" A lot of other commenters are raising points that the author was kind of a dumbass. But as it turns out, I too fuck up every so often, so I'd like to know what happens when I do.

The article goes a long way towards answering those questions. I'm probably not going to get an electric car anytime soon but I don't see anything in the article as particularly anti-Tesla or even anti-electric.
Excellent. It became more developer friendly as well. This is going to be my default browser!
>Can you toggle the regenerative effect when you lift off the pedal?

You can, but this would slow you down more than gravity, the transmission, and the friction of the road alone would.

The only thing you can really do is change to neutral. Dual-clutch transmissions in high-end sports cars have already been doing this for years, though they don't do it based on the angle of the road surface, since if you're going fast enough, it's beneficial to do it as often as possible.

And 50 meters can be the difference between a tow and making it, which is my point. Yes, I am aware it is a small amount.

"just a list of commands to run on the machine."

A provisioning script is essentially just a list of idempotent commands to run on the machine. But given the way that docker works, idempotence is not required -- if you change a command, Docker rolls back to a known state and runs the command.

A provisioning script might be slightly "higher-level" than a Dockerfile or shell script, but I find the difference is minimal, that the number of lines of code required are similar. Many provisioning tools provide libraries of pre-built recipes you can utilize; Docker provides a repository of pre-built images.

If they poured crushed rock directly onto the belt, not much would be left after only a few kilometers, what with all the curves, slopes, and vibration. The belt will also be damaged beyond repair if you keep rubbing rock against it.

So they probably put the rock in boxes and put the boxes on the conveyor belt. The tiny guardrails on either side should be enough to keep the boxes on the belt. Small pieces might spill over if the boxes aren't covered, but most of the cargo will arrive intact.

Chinese Government Will Invest CNY20 Billion to Promote IPv6
Cool, I had the same basic idea at one point to do this with an Arduino. I wanted to have infrared emitters below the keys, and have an infrared sensor somewhere slightly in front of the keyboard (but at finger height). Your fingers should reflect infrared light back to the sensor. Not sure how accurate it would be, but I think it would be accurate enough to capture sweeping gestures such as your hand moving up/down for scrolling. Something like this wouldn't be precise enough to replace a mouse, but definitely useful enough to improve workflow (scrolling, switching between workspaces, apps, shortcuts). If the keys were clear, I'd imagine it would be even easier for the sensor to determine where your hand is based on how much infrared light your hand is reflecting back from different positions.

Very intuitive stuff, I hope to see this in laptops soon.
Terrible back-of-the-envelope math disregarding any kind of loss or inefficiency, and assuming a magical DC->DC power system which would convert a car's 14.4V alternator source to something suitable to charge a Tesla without losing anything:

A "normal" modern car's alternator can put out ~100 amps at 14.4VDC. That's a maximum of about 1.5kW, which will charge a Tesla at a rate of about 2 miles of driving per hour of charging, again assuming a magical efficiency.

The reality is that the car's own systems take at least a few hundred watts and alternators aren't built to run at maximum load all the time and are likely to fail after a while running near capacity. Plus, the Tesla doesn't, to the best of my knowledge, contain any sort of DC->DC hardware capable of bringing 14.4V up to the necessary charge voltage, and even if it did losses would be at least on the order of tenths.

So, even with a good, running car and a theoretical alternator, you'd be waiting a very long time next to the running car (and burning a lot of gas) before your Tesla would go anywhere.

Obviously it would be possible to build, for example, a tow truck with much greater charging capacity and as time goes on we'll probably see at least a few of those in real life. But the fact remains that gasoline provides an excellent energy density in a convenient liquid form and that for certain edge cases, its conveniences will be hard to beat.

The Coke Monkeys article is fascinating:
http://bugbear.com/cokemonkeys.html
Personally I loathe having to use any sort of GUI because in general its slow and I cannot as easily automate tasks to customize my workflow.

There's a lot of research out there that provides a lot of evidence that GUIs in general aren't slow, assuming they're well-designed; they feel slower to people used to CLIs and keyboard-driven interfaces, but when you actually measure objectively with a stopwatch the results tend to favor GUIs.

I think it's the second part of your statement about automating tasks where CLIs really have the advantage. For GUI programs to be automated they have to provide a scripting API much more complicated than just an input and output stream -- and then, of course, you need a scripting language to bind them. OS X's Automator is a really great glimpse of how that could be done in an entirely GUI fashion, but it also shows the limitations of such an approach -- most of which aren't in Automator itself, but the very fact that applications need to be written to support it. (Of course, some of the built-in actions let you run AppleScript or any shell language programs.)
