The main thing people complain about in the HoloLens is the field of view; I don't know how much these chips are the bottleneck for that, but it seems like a problem you can throw more cores at, so I'm sort of expecting them to solve it that way, but I don't know a whole lot about hardware.

I thought it was interesting that they mention using a yagi.

For hunting a strong signal, the traditional tool is antenna with a deep null such a loop antenna. The reason for this is because the null at a point can be very deep relative to the average response-- e.g. maybe a small directional antenna has 10dB difference between the front and the side, but a small antenna engineered to have a deep null can easily have 40+ dB of isolation between a null and the side. To search for a signal using a null you aim until the signal goes away and you go in that direction. :)

And it's easy to construct antennas with only two (or one) null.

For a directional antenna like a yagi you have various reflections hitting the antennas sidelobes, making it harder to read.
Given the proper age, teaching kids to use syringe/vials or having a school nurse that can administer epinephrine would be a much cheaper alternative.

EpiPens are purely about the delivery mechanism. Stabbing a syringe into your thigh and injecting a predetermined amount of epinephrine into your leg isn't majorly complicated.

Maybe having a single pen on the kid and vials/syringes at the school would be a cheaper option.

I've been in relationships where I've spent a weekend at hers, but tell her I need to go for a walk by myself. It may come off weird, but most of them have been cool with it once I explain and offer reassurance that it's not because the relationship is fracturing.
> a $10 bottle of epinephrine and a $1 syringe can save a life

You're not prevented from using that method and some people and a lot of emergency services (that have relevant training) do. There are problems with that too though, epinephrine isn't completely stable and properly injecting when you or someone you know needs the shot isn't an easy task.

What the FDA is and should prevent are devices like the Auvi-Q that couldn't inject the proper amount reliably.
Ask HN: Valuable Training Course or Class You Have Taken?
I am a senior software engineer that hopes to take the leap to management. My manager has offered to pay for a training class for me. Have you attended any training or taken a class that you found helpful for your career? Two areas that I see as valuable/interesting include:

1) Training that would help me land a software manager job

2) Machine Learning/Deep Learning - New interesting area of technology

The training can be anything from an online course (Udacity, Udemy etc...) to a 3-5 day in-person class (must be in Chicago).

Any advice/personal experience would be greatly appreciated.

Thanks
Consider this: every time you get into a car, you are putting yourself into life-or-death scenarios that greatly depend on the class and quality of car you've chosen. The government enforces some minimum safety standards for any registered car on the road, but above that, you pay for safety - quite literally.

Does the government prevent the sale of cheaper, inferior cars just because higher-priced cars are substantially safer?

Why should medical devices be any different? If the barriers to entry (e.g., costs associated with FDA approval) were lower, then we'd absolutely have some inferior EpiPens on the market. But we'd also have a lot more options, and all of them (even the best) would be ridiculously cheap compared to what we're seeing now. Wouldn't that be better overall for people who might not be able to afford one at all in the current system?

That same thing applies to WordPress. To goal isn't to replace all the free plugins or anything.

Have you ever actually dealt with Drupal and it's modules? The process to install and upgrade them is extremely poor. WordPress is much more technology advanced in that area. The only way to sanely deal with modules in Drupal right now is by using Drush. While using Drush is great and CLI tools will always be needed, other options have an opportunity here.

Not necessarily. The cost of backtracking on a bad branch prediction on a device like a phone may be so great that implementing an ANN could be worth the effort to implement.

I'm not as familiar with mobile phone architecture as with that of PCs, but the number and types of operations influenced by the device's various sensors (light sensor, GPS, accelerometer, gyroscope) could conceivably be more than normal, naïve branch prediction can handle effectively.

I'm pretty sure you could put together epinephrine and a syringe for a few bucks. And sell it for twenty or so with a healthy profit.

But you can't, can you? Is that because of free market worship, or worship of the regulatory state?

Evidently at least one lawsuit prompted the drafting of this semi-august publication. Good government means, in part, consistent and reliable application of rules -- even if it's as minute as the distinction between bolts and screws!

This, in my mind, is a very particular example of the general case of good government often being inefficient governance. We are protected against tyranny, in an infinitesimal and indeed ridiculous way, by colorless bureaucrats dedicated to the proposition that every bolt shall be labeled a bolt, and each screw a screw, regardless of the power and wealth of those who might carry them through customs and seek to see them mislabeled. Godspeed, writers of CBP Informed Compliance Publication minutiae, godspeed.
This is a GPU rather the a DSP (the tricky part is rendering not filtering). Core count is a bit of a pointless metric unless you know how big/ powerful a core is.

I like the idea of a self contained VR headset with no wires, but I don't think going to see on for ab a decade, there's just too much processing power needed for a realistic experience. I hope I'm wrong!

Edit: It appears this is in fact DSP (digital signal processor). That's a huge amount of power for dedicated signal processing, I'm intrigued to know what can be done with it.

But don't think that your idea indefinite comfort and happiness is everyone's version of mediocrity - to many, it's the definition of wild success.

We had a tornado briefly touch down in Brooklyn maybe 7 years ago and the sky definitely turned that green, it was the first time I had experienced that.

Even though there are cars with a 5-star safety rating, you can still get ones with a 4-star or even 3-star ratings. So I would say the answer to the original question "Does the government prevent you from buying less safe cars" is "No".
You don't experiment on your production planet.

But the problem is no one is day trading to contribute to the balance of the system. They do it purely to make money or because they have a gambling problem.

Right. Either that, or they're encouraging day trading from behind the scenes (which would totally explain the financial news networks). And that's why the system frightens the shit out of me.

Please don't blame the free market for these high prices. This is a highly regulated medical device market with patent protections and insurance market complications.

The price hikes would immediately attract lower-cost competitors if this were truly a free market.
The statement is ambiguous, so it can still be valid. However the use of "length" twice in the same sentence to describe both the dimensions parallel and perpendicular to the crack is likely to confuse some readers. Some people's brains are not going to free the "length" pointer halfway through the sentence.
> The government enforces some minimum safety standards

I think this understates the safety regulations for automobiles by quite a bit. Maybe there's an example of an industry which makes lightly regulated, dangerous products, but I don't think cars are it.

> Improving asymptotic bounds. Providing functionality typically not supported by common data structures.

It's nice to know that you remember stuff from the textbook. However, how often do you need to do something like this for real production code? Depending on what it is you normally do, it's entirely possible that you need to do this every other project. It's also possible that you never have a real need to do these things. (It's also possible that you never have a real need to do these things, but you do them anyways, which is far, far worse.)

> The law of large numbers certainly applies to >100 KLOC codebases, unless your bug rates are somehow magically two or three orders of magnitude lower than the average.

True, which is why I'm pretty confident that 15 years of Smalltalk development on many large code bases without running into a heterogeneous collection debugging conundrum is possibly a valid data point.

Contrast that with an endless parade of "hubris coding" in the same timeframe. My impression is that the damage caused by "hubris coding," or the gratuitous worship of "cleverness," far outweighs that caused by insufficient type information by 2 or 3 orders of magnitude. If you're going to be clever about applying your clever, you need to apply it in a fashion where it gives your company's business the biggest bang for the buck. Most coders in their 20's are just trying to impress their fellow programmers.

Agreed. Playing on a 2nd division French team is not indicative of a brilliant con.

Also, some of the information in the article strains credulity: Without balls to practice with, the team was restricted to doing a physical training session. They had no balls to train with?? I've seen some down-and-out footballers, and somebody always had an extra ball or two in the car.
I think the biggest takeaway from this is diving into their research about the human consumption of a lot of information (UX, if you will).

I know NASA and the Air Force spent a lot of time seeing how humans pilots digested information under stressful conditions etc., which basically gave us the modern aircraft cockpit layout (and the fairly standard arrangement of the 6 critical instruments that are used in all small aircraft today).

I wonder (and hope) that this research also extended to the arrangement of critical data on a dashboard so that maximum information could be gleaned with as little eye (or mouse) movement as possible.

Good point. Intuitively I think markets would attempt to approximate probability * cost i.e. expected cost. However there is something intensely wrong how market is functioning with environmental issue. It appears that markets is trying to view the expected cost as debt that needs to be paid in future. The value of debt would be much larger in future but markets seems to be ok with current return. This could be a great theoretical hole in efficient markets theory.

Firstly, the standards and regulations a manufacturer needs to meet to get even a single car on the road are staggering - probably comparable to FDA approval in complexity. Also, the testing of single components and complete vehicles is extremely comprehensive.

Secondly, there's a huge difference between the two cases that you're not considering: medical devices are designed to interact directly with the human body and alter it from within.

True - the government's automobile safety standards are far from trivial, but there's no denying that the difference in safety between the cheapest smart car on the road and the safest car on the road is huge. In a head-on collision between the two, there's absolutely no contest.

Asking why the government should allow an EpiPen competitor with a 0.1% higher failure rate is akin to asking why the government should allow people to purchase small, cheap cars.
In the study below, moms of kids with severe allergies were trained to use the EpiPen. Six weeks later in a simulated test, only about two out of five were able to successfully deliver a lifesaving dose of adrenaline.

As a library author, you can't search code written by users of your library.

What kind of nonsense is this? The library author doesn't need to do such a search! The library users in Smalltalk would do such searches. Access to source was the norm. Decompilation in Smalltalk is trivially perfect, excluding local variable names, so closed source was fairly pointless.
Now, a solution to bring that intrusive drone down
It doesn't turn out this way. People don't rigidly stick to their cars when road capacity reaches its physical limits. As driving becomes less desirable, people adjust their behaviour. They drive less and use alternatives.
In that case, there is no ambiguity when it comes to determining who's responsible, unless the DMV or whoever allowed you to drive it.

> The price hikes would immediately attract lower-cost competitors if this were truly a free market.

Any participants in a free market for a product with inelastic demand (e.g. something you need to stay alive) and non-trivial entry costs immediately implements price fixing in the absence of regulation.

When life-saving devices that require a significant supply chain to manufacture capture the bulk of consumer surplus from the majority of potential customers (and the poorest are left to die), the free market is working as intended, efficiently allocating resources to maximize profits.
