For fun, KE = (1/2)mv^2 = 32 MJ -->[mathing intensifies]--> a 1,000 kilogram car moving at about 565 mph carries 32 MJ of energy, which is what 1 liter of gasoline carries.

A gallon is about 4 liters, so at 100% efficiency it could get a 1,000kg car to ~1,130 mph or a 1,500kg car to ~925 mph.

For reference, the same calculations tell us a quarter-pounder with cheese could get a 165 lbs (75kg) human up to 540 mph.

Government money/budgets isn't that precise, income from taxes are variable, for example. Also most countries spend more then they make anyway (deficit).

It's accounted for as revenue via fines and spent according to the normal budget.

What engineering solution would have prevented this driver's death? She knew a train was coming from the bells, flashing lights, and closing gates. She had at least 30 seconds to react.

If you mean a more elegant solution -- a different 3rd rail design, e.g. -- would have saved the lives of the people aboard the train, that's possible. In the event of a mutli-ton train at 60MPH hitting a multi-ton truck sitting on the tracks, we should not presume that's the case.

The better scenario is to heed the bells, flashing lights, and protective gates and get off the tracks. It's a difficult engineering task to ensure people heed clear warnings.
They then also have a working knowledge of the psychological, human, and monetary costs of a never-ending war against our own citizens, the inability to distinguish between crime and addiction and disease, the extremely regressive nature of drug addiction, recidivism rates of minor criminals in to hardened felons, the stifling effect of a felony conviction on upward mobility, and everything else proven to be utterly destructive about the war on drugs.

The majority is rarely well educated about anything. Pretending their support on the war on drugs is somehow more informed than on bank bailouts is silly.

At some point the performance margin grows so close that it's irrelevant to almost any application. IMO, it's already there for a broad swath of application classes. For those inner-most-loop, optimizer-has-failed-me cases, Rust can still fall back on unsafe code.

I'll note that this kind of skepticism has been going on since John Backus[1] was heckled over using (ahem, "wasting") then-precious CPU time on compiling code using the first versions of FORTRAN. His detractors (and everyone else) quickly learned the value of conserving programmer time vs. CPU time.

The exception to what I said in the other post is sometimes lower branches of government hold on to their cash for various purposes and spend it however the lower branch wants to essentially.

>1. Using YT as a proxy for overall attention

'Overall' attention is never a claim. This is simply building upon the views data with what is measured around how far people watch in a video.

>2. Advertising isn't a straight line number of attention to sales

There is no mention of sales in the post. It is comparing the price of the superbowl spot with the number of attention minutes. There are many factors which can serve as a measure of success, in this case it is looking at how people are watching the video after the ad spot.

>most CMO's wouldn't take this type of napkin math very seriously

Attention minutes is a fairly powerful measure. Ex. Upworthy uses it to determine which videos are most likely to be shared. The goal here is to show one way it can be used. In practice, it would be used among other measures an agency or company has- as you describe above.
That's going to look so retro in 2020 when they get the budget to replace it!

Just to clarify. We first saw that the ratio was "near" the golden mean. The closer one comes to that ratio the more likely one will see "strange non chaotic behavior". So yes I agree it is just close (although now there seem to be hundreds clumping just above and just below the golden mean and we think we have a dynamical reason why but are still running simulations). Thus near golden mean -> higher probability of seeing SNC which is what we saw. It is evidence in support that we are near enough to the golden mean to be irrational enough to see SNC behavior.
Hope this helps.

My intro inorganic-chem class had the best safety video, described as one "Dr Anxiety". Among other thing like a glass tube being into a stopper that ended with blood spraying everywhere, it had someone in a lab coat pick up a 1L reagent bottle off a shelf, eye it for a while, and say, "Hmm.. I haven't used this in a while, but I'm sure it's still good.". As soon as they turned the cap, it exploded into a giant fireball, complete with the lab guy running around on fire. Rewinding and pausing the video revealed that it was diethyl ether.

I kind of wish I could find a copy of that safety video....

So you were probably "the guy," one of the last holdovers from the true enthusiast days around the exact time I was learning electronics. I remember distinctly at the three (!) locations within driving distance of my house, there was always one, and only one, person that really knew their stuff and would help us out. At the location closest to my house was a former U.S. Army technician named Gus, who was wickedly intelligent.

It may not have been you directly, but guys like you at Radioshack in the 90's made a huge difference in my life. So on behalf of myself and the others you undoubtedly helped, thank you.

It's really terrible that poor management drove people like you out instead of propelling them up.

That's not "private investors", that's the Chinese government. This would have had clear political implication (the Chinese already hold a lot of US debt etc etc), but regardless, it was Nation-States making moves -- basically the only players in the game, on that size of petty cash.

On the other hand, you have no choice but to use unsafe code in C++; that is, there's no line between code that is guaranteed to be memory safe and code that risks corruption and undefined behaviour.

In any case, the route people will hopefully take is to write the code in the obvious way, with bounds checks and all, and profile. Functions which take significant amounts of time can then be optimised more manually (and, bounds checks usually aren't the bottleneck).

Building maintainable mongodb queries using query object and mongoid in ruby
Games are one of the areas where it is a bit foggier as your rendering loop is incredibly sensitive to performance problems.

You have a ton of work to do and cannot take more than 16.7ms (60Hz) to do it in period. Heck given the recent move some have made for 144Hz monitors it leaves you with less than half the time (6.9ms).

Not to say that C++ is the only way to pull it off, just that games are a soft-real-time system which therefore have stricter requirements for performance.
Or as another example, quoting from http://en.wikipedia.org/wiki/Paper_shredder :

> After the Iranian Revolution and the takeover of the U.S. embassy in Tehran in 1979, Iranians enlisted local carpet weavers who reconstructed the pieces by hand. The recovered documents would be later released by the Iranian regime in a series of books called "Documents from the US espionage Den".[8] The US government subsequently improved its shredding techniques by adding pulverizing, pulping, and chemical decomposition protocols.
I'm not saying I agree with that line, I'm saying that this is what the (Bush II) government was signaling at the time. (Which for them was likely true -- losing Lehman, Goldman and AIG in a month would have destroyed a world of wealthy executives.)

Greece is another matter; the problem there was not with the bailout, but with stupid terms imposed by the troika to cover debts. In fact, if the troika had behaved with Greece in the same way the US government did with US banks (putting up cash right away, no questions asked), Greece would not have suffered what it did.

To be more specific, because the parallels may not be evident, the IP tactics of a burgeoning industrial nation are likely to be underhanded because the system favors the established power (see patents within the US). I find it extremely amusing to watch the US crow about IP when its very own industrial base was built upon foreign tech... just like China today.
Quantum Experiment Shows How Time ‘Emerges’ from Entanglement (2013)
> Mathematics has no side effects.

I'm aware the author is a professor of CS, but this is a statement I always see people originally trained as programmers claim, and as a mathematician and a programmer I respectfully disagree.

Mathematics does what you define it to do, and if you can communicate your idea to another person it doesn't matter whether you "mutated" a variable or not. Likewise, you could say that there's no such thing as mutation in programs because the value of a variable in a language that supports mutation depends implicitly on time; you just don't express that in the source code. It's a matter of perspective, and more perspectives are often better than fewer. In math if you want to index a variable to have "pretend mutation" to avoid confusion you can, but there's no rule about it. If you feel the best way to communicate that idea is with mutation, then that doesn't stop it from being mathematics.
I can see why they didn't include this. I don't know about Portugal, but I've driven in Mexico and I know people who have attempted to drive in Bali. If you're not from there, I don't recommend it. You might be fine on most of your trips, but eventually the assumptions you have about driving from your home will be violated, and there will be an incident that will cost you money. If the car belonged to this company it would also cost them money.

One of the perks of cheap locations is that hiring a cab is cheap. Also you can ride a bike. Also driving is the least relaxing way to experience any of these places.
One of the points people don't get here is that you work with the data you have. And it is not perfect data.

Actually I think it's not out of the question now. The recent advances in recognition accuracy are mostly due to deep neural nets. The research is all published open access, and the cutting-edge tools are mostly open source (Theano, Torch, Caffe). Training neural nets is actually a lot simpler than the old methods of doing speech recognition; I think it's much more accessible to a small team. The only really difficult requirement is lots and lots of clean labeled data for training.
Hey..would love to talk to you and others and find out bit more around the issues..I am in sf for next few days..
Regarding diet and stress - we started with diet about seven years ago. She was a very picky eater and we kept the snacks she liked in one cabinet, and when she wanted something she would come take your hand and drag you to the cabinet. If you asked her what she wanted, she'd take your hand and place it on the item (no pointing, no grabbing it on her own).

The day we implemented the diet, I took her to the cabinet and opened it up. It was empty but for a few things she still could have, and we eventually filled it with things she was allowed.

Flash forward to today, and her favorite foods are almost entirely vegetables and meats. She is very restricted - no dairy, gluten, soy, corn, sugar, any grains, and little processed food overall. She has been sick (cold) once in the past three years and attends elementary school.

The stress of a child not sleeping for years far outweighs the stress of meal planning and preparation, at least in my family (wife is at home).

I'm not a doctor (if that wasn't obvious already), but diet worked for us and she quickly realized that she would have to eat from choices we provided. There was no more than maybe a day of any negativity about it from her. Her diet now is incredibly healthy, and my wife is creative to make things that are safe alternatives to stuff that other kids are eating.

Some diets take more prep time than others, but I don't know that I've ever heard of stress to family or child as a stated objection to try it.

It is pretty standard to give good references to bad employees in order to make one's competitors suffer their incompetence. Likewise all things being equal one does not want a great employee leaving to work for a competitor. Overall this is widely understood so nobody pays any attention to references.
I am not sure where you are geographically so and some of my advice will depend on your location and, more specifically, how many potential positions there are.

First off, if you have some programming skills, and it sounds like you do, do not go for internships. Internship positions seem to be very specific to students. They may want to check with your University and such, which is a no go in this situation. Instead go for "Entry level" or "Junior" development positions. A lot of these will be very junior and won't expect a huge level of skill. Make sure to set your salary expectation accordingly, to make yourself marketable.

Second, if you are planning to continue to go to school put down the fact that you are attending. You probably won't be asked, but if you are asked about your current status say you are on hiatus. I would be intensionally vague. A lot of us had rough times in school for a lot of reasons! Talk about how much you enjoy school and how important it is for you to be successful at it and how the real world experience you are gaining will help in your education. These are all true statements. I would not come right out and explain that you were put on probation for academic reasons.

Next, and this is probably the most important part, apply for a lot of positions. A lot of people really mess this one up. They read the perfect job description. It fits them just right. They apply and wait. Don't fall into this trap! Getting a job really is a numbers game. Apply for as many positions as you can find in your chosen field and area. I have often said, and have yet to be proven wrong, that is you apply to 50 jobs, you'll certainly get one.

Finally, on a personal note, chin up! School and this time of your life really are hard. That's nothing to be ashamed of! You have not ruined anything and you have a lot of great days ahead. It's great to hear that you are seeking help for depression. Keep going. You'll find your way and this will all work out.
Yes, they only rank students they interview. Those students who don't match before the rankings are exhausted "scramble"; they speed-date programs that still have openings in the hope of matching, so the leftovers are not randomly assigned. (Whether the outcome for them is better than random is hard to say.)
HTTP/1.1 is also pretty bloated, it's just half the features nobody bothered to implement correctly (pipelining, for instance). HTTP/2 is much the same.
There's no shortage of FOSS software for automatic speech recognition. Most academic research these days uses the Kaldi toolkit (http://kaldi.sourceforge.net/about.html), which has an Apache license.

There are (at least) three problems that prevent the widespread availability of FOSS speech recognizers:

1. Data. Large corpora are available via Penn's Linguistic Data Consortium (LDC). Big academic institutions can afford their all-inclusive licenses; small corporations have to settle for their expensive a la carte options, and startups and hobbyists have to go without. Fortunately, there is now more and more freely available data, such as the LibriSpeech database (http://www.voxforge.org/home/forums/message-boards/audio-dis...), which is extracted from the LibriVox website (of public-domain audiobooks).

2. Task-specificity. Speech recognition systems need extensive customization to the intended use case to achieve good performance. Conventional wisdom is that your recognizer can be tuned to work with a wide variety of speakers, or support a large vocabulary, but not both. This customization requires lots of time, data, and expertise.

3. Expertise. Speech recognition development is a PhD-level activity. After 5 years of stable or declining real income, smart students either go work for big bucks at a large multinational, or can't get a visa and go back to their home country.

While there's some hope for #1, #2 and #3 aren't going away anytime soon.
This is a short, fascinating read. I can't afford to live in San Francisco. But if I could, I'd certainly be concerned about things like this:

In 2006 -- 100 years after the great quake
of 1906 -- a USGS representative stated that
if an earthquake of the same magnitude hit
the city that day, it would destroy nearly 40%
of the city's buildings. The geologist also
noted, “All the areas built on fill, such as
the Bayfront, Marina district, financial
district, and SoMa [south of Market], will be
very vulnerable."

There is also a very enlightening map. In addition to fill, a large part of the city is "built on levelled sand dunes".

A few years ago, I read that cuba had like 250 MBPS for the entire island. A cuban guy told me that dial up was as expensive as a cheap appartment. (I dont know if their band has broadened, because Venezuela said publicly that they would connect a cable to them, but never heard of it actually happening).

Considering the extremely little bandwidth they have, a homebrew wireless 'cable' from Florida or Mexico would be a game changer for Cuba.
