"I can happily imagine that every child in the USA gets to find out if they are any good at hitting a baseball (#). So we can be fairly sure that the population of possible baseball picks is as wide as it can be - and is a proper bell curve."

That's a very good point - thanks.

I suppose the same point could be made, even more emphatically, for skiing.

"most sports probably still have plenty of "moneyball" left on the table"

Are you sure you get a similar effect? A quick search suggests niacin behaves quite differently.

"Among "salvageable precursors" (i.e., Na, Nam, NR), a lot of focus is on NR these days because apparently it activates the "anti-aging" sirtuin genes at high concentrations too compared to Na and Nam which only activate those "longevity" genes only at small concentrations and deactivate them at higher concentrations."

As explained in the article linked at the top ("LWN recently looked at the kernel's max() macro"), the issue isn't one of optimization, it's one of syntax. Sure, a decently optimizing compiler can optimize __cmp_once in to a constant value. However, C99 requires that non-VLA arrays have a size that is a constant expression, which is a syntax thing; even though GCC knows that __cmp_once evaluates to a constant value, the resulting C coming out of the preprocessor is of the wrong syntactic shape.
Sort uses -t and -k, cut uses -d and -f. Your point is valid, of course - the options are not consistent across the unix tools.
You could not possibly have read it and earnestly have that opinion of the piece's substance.

edit: To clarify, you may reasonably either like or dislike it, but to claim it's lacking substance is trivially demonstrably false.
One of the things on my abstract wishlist is a hope that we as a culture can move away from this trend of saying terrible, awful things under the guise of 'irony'.

> In an interview with Howard Stern in the mid-’90s, the radio host asked him about a character in the comic book anthology the cartoonist was then promoting. Stern called Sody Pop “a hot chick with big cans and nice legs.” Kricfalusi responded with a smile: “She’s underage, too.”

I think anybody would raise an eyebrow at that. It's a messed up statement. But because it's in the context of this conversation with a shock-jock, because it's _clearly_ ironic, it's _clearly a joke, why are you taking it so seriously, lighten up_, nobody called him on the fact that he was saying something incredibly messed up, and maybe if somebody had, then this would have come to light earlier.

I understand that freedom of speech is great and people are free to make whatever jokes they want. But just because they CAN doesn't mean they SHOULD, and if people stopped making jokes about being a pedophile, about being a predator, about being a nazi or a misogynist, I think we'd be better off.
While that might be the case, I'm not sure we have enough information yet to assume that's true.
What actually worked for me, but I can't do it with my current job: bi-phasic sleep.

I did this while in school, I slept 2am-7am and 4-6:30pm. Pro: you learn to fall in to deep sleep very quickly and I would often have lucid dreams and you can get away with slightly less sleep. Con: if anything gets in the way of the afternoon sleep phase it feels like missing half a nights sleep...
I don't think you get to decide whether or not I perceive something as substantive.
I think you really have to appreciate art separate from the artist. Many great figures in history were shits in real life. Paul Johnson's book Intellectuals is pretty much a gawker-style hit piece of Marx, Sartre, Tolstoy, Rousseau, Shelly, Brecht, Russell, and others - but it's not wrong. Hell, John Lennon was a dick to his pre-Yoko family.

Don't romanticize people and I think you can pretty comfortably enjoy both Netflix and the daily news. Ren & Stimpy is funny in its own right.
Saying someone who was a mechanical engineer was "not really a scientist" kinda does him a bit of a disservice.

Interesting, I'm not sure what to expect. Can you code up the permutation test and share the results?

Also, in what cases would you say a permutation test would be unnecessary, only one independent variable? I tried to choose a very simple example.
Since switching from 1-5 start ratings to like or dislike it's gotten much worse.

The grand bargain is impossible, not due to NIMBYs and zoning conflict but rather because more funding for the MTA won't help a damn thing.

The MTA has repeatedly been caught lying to the public about their finances, hiring ghost employees, etc etc. They have the highest capital costs in the world, full stop -- it would cost them a billion dollars to erect a mailbox.

The MTA's annual _capital_ expenditures budget is already larger than any transit system in America. Their operating budgets are among the healthiest in the world, due to very high farebox recovery ratios on the buses and subways, but the fares go up without bound and there is somehow never enough money to get existing service back to 2010 levels, to say nothing of modernization or expansion.

There's no money for new transit in New York City because no one in City Hall _or_ Albany is damn fool enough to believe that tossing additional billions into that bottomless pit will yield meaningful results.

Lastly, property taxes are pretty low in NYC. Property tax is less than 30% of total City revenues. Massively expanding property tax bases in localized areas will not move the needle on the city's budget.
I suspect it depends on the age of the students. In grade school when kids are learning to read and do addition, it's hard to imagine anything more core than that and science/history taught at that age is more about getting kids exposed to those concepts rather than actual learning. But once kids get to secondary school and English transitions to British Lit, American Lit and other variations on "read books and write an essays", the actual class time seems much less important than science classes where high school students actually learn the core tenets of Bio, Chem and Physics.
Strassman is certainly more trustworthy than McKenna =) I should have been more targeted in my question. I was wondering more about the pineal gland as the source of production than if endogenous DMT exists. According to the link below, they have Rick on their podcast saying that DMT is produced by the lungs and then transported to the brain, maybe stored in the pineal gland? I’m gonna have to give this a listen.

The default key binding set is a de facto standard for double-pane file managers. I personally used Total Commander for a long time until I switched to Mac, and I really missed a FM with the similar hotkeys.

But I understand now that it's not what all Mac users expect from a file manager. I'll make an option to choose the hotkeys on the first launch [1].

Yes, that pretty much confirms what I wrote above. Your point being?

Please read the article and compare what we know about Cambridge Analytica vs what the Obama campaign did, it is comparing snipers with someone setting off fireworks.

> I was so excited about auto-pilot and dreamed of getting in my car and sleeping while it made cross-country trips. So much for that, that seems way far out.

This is more a hijack than a direct critique but I think the general issue is the assumption that we need a private vehicle for that.

Trains are perfectly capable for bringing me from A to B while I am sleeping for years now.

Despite the ridiculous price point, I enjoy the portability and battery life of MacBooks. Almost all of my ML projects are on AWS or Linode or something, but if I were to even consider forking over for a MacBook Pro w/ a GPU, some sort of GPU ML support would be a must.

Anyone have experience with Radeon deep learning libraries? Thoughts?

(not trying to have a debate about the obvious impracticalities of mac laptops – just curious if anyone has done ML w/ Radeon libraries)

Why should it be a function? It can be a method on sequence like objects (trait)...

I'd like to see a citation for the prevalence of adultery. Studies I've seen cite 20% of married men have committed at least one act of infidelity, and that the current percentage is almost twice what it was in the seventies. That seems to me like the vast majority of couples get along just fine in a monogamous relationship, and that culture has more to do with infidelity than primal need.
Go has very little in common with either of those languages except a GC. Go is statically typed, natively compiled, a good 10-100X faster, and it has great concurrency/parallelism stories. It also lacks classes and exceptions.

I honestly worried about that when writing the comment. The car should have avoided it (based on Tesla’s usual claims).

But Tesla and everyone else says the owner is still ultimately responsible because AutoPilot isn’t a 100% situation.

If my car did something funky like randomly accelerate or turn hard at a given intersection and the manufacturer refused to fix it I’d stop driving through there.

Why push your luck?

I truly don’t like blaming the victim. I’ve been very critical of Tesla lately for their claims and safety issues.

But I don’t understand this man’s decision at all. It doesn’t seem reasonable.

I wish I knew why he kept using the system in that area.

The ONLY idea I can think of is when the car got an update he would try again to see if it was fixed and of the tries was sadly the last.

while idea of injecting sulfates into atmosphere does not sound promissing, idea of not doing any geoengineering and trying to just keep the current climate is even worse, because huge portion of the earth is inhabitable now.

And there are many alternative methods, more controllable methods for geoengineering.

A particularly interesting one that doesn't get enough attention is usage of solar updraft towers.

If towers are sufficiently high and numerous, they can carry up dust and small particles from the surface, inducing formation of clouds, they can improve convection in the atmosphere, acting similar to mountains. Over the sea they can prevent huricanes by reducing the temperature gradient. And a chain of them would help to bring more moist air from shore to the desert regions inland.

It really depends on your area and living situation.

I have a place in suburban Minneapolis and I could (and have) left packages sitting on my doorstep for weeks while on vacation. Still there when I got back - only a single lost package over about a decade now.

I also have a place in Chicago. A package left outside at the door would be gone within hours as I live directly off a very busy street. Even if put inside, if the door gets left unlocked or ajar a bit you have a very high chance of the package disappearing. Packages get delivered to the office or not at all when I'm in town.

I agree re: having zero interest in driving to the nearest locker though - I'd just go to the store. It's possible they will reach the density in Chicago where I can walk a half block - which I'd be okay with - but I can't imagine that being cost effective for most areas of the city.

Tesla actually has that, it's not widely documented but you can do a voice command of "Report bug" followed by a brief audio description and it's uploaded to Tesla.

Rust enforces proper acquisition and releasing of resources, and that is very cool. For that it uses linear types, which is beyond what ML's type system can achieve. It allows rust to manage memory safely with no GC. The type system can show the compiler when to release resources. I think that can be done in C++ and maybe Haskell but Rust has it baked in.

Think about all the low level resource management: network ports, files, heap memory... That's what rust does better.

Check ATS for a ML-inspired language with some resource semantics closer to rust and stronger control and correctness primitives. http://www.ats-lang.org
this is what frustrates me
I'm finding this comment a little hard to follow, but let me try. Obviously people are always going to disagree about particular calls, but on a principles level, from my perspective, we're pretty consistent.

If you're asking about the Haspel story, I wouldn't say that was an interesting new phenomenon in HN's sense, nor was there nearly enough information to feed a substantive discussion about it. To be honest that case wasn't even really a close call. Some new users got upset at us for moderating it, but as I tried to point out at the time, that was mostly because of unfamiliarity with how HN works.

An intense political profile ("if they'd cover it on TV news", as the site guidelines say) often feels like information, but usually isn't, in HN's sense. That doesn't mean the story isn't significant. When we say a story is off topic here and/or when we turn off flags on a story, we're not judging the story's overall significance. We're concerned with whether it fits the site guidelines and whether the community is able to discuss it substantively.

I think the answer to most of your questions probably lies in what kind of site HN is trying to be, and what kinds of site it is trying not to be.
Understanding system load and load averages
Yeah, I really don't buy dang's statement on the matter. This is Entertainment Tonight content. It's quite literally something that would be in TV news. It's a shame of a situation, but I don't see what makes this any different.
Should be. Obviously people get their notion of "autopilot" from science fiction, not from aviation.
It’s a mitigating factor is Tesla’s favor.

But mostly... I just don’t understand it. It seems like such an odd decision by the driver I don’t know what to make of it.

It’s very unfortunate that he died, but that doesn’t mean we can’t ask questions/criticize what may have gone on.

The most insane macro in that is this monstrosity:

#define __is_constant(x) \
(sizeof(int) == sizeof(*(1 ? ((void*)((long)(x) * 0l)) : (int*)1)))

If x is a compile-time constant, (void* )((long)(x) * 0l) is equivalent to NULL, otherwise it's just a regular void* . And if both sides of a ternary are pointers, the rule is:

If one side is NULL, the type of the ternary should be the type of the other side (int* in this case).

Otherwise, if one side is a void* , the type of the ternary should be void* .

So if x is constant, the type of the ternary is int* , and if it's not constant the type is void* . The sizeof(* ()) around it turns that into sizeof(int) or sizeof(void), and in the GNU dialect sizeof(void) is 1, which is different from sizeof(int). Whew.

What I want to know is what's wrong with __builtin_constant_p.

Not in the United States. Rail coverage is terrible. If you can get to your destination, good luck doing that without switching trains.
Very well said. One would probably have O(log N) potential partners for activities they care about.
Agreed entirely, in some parts of the world you can even drive your car onto a train, have a nice meal, watch a movie and sleep in a luxurious cabin. Wake up the next morning and pick-up your car.

I think demand for trains has diminished which is why they're not as nice as they could be; However I found plenty of nice trains on offer in Europe and Asia.
But do you still qualify if you are sitting on a pile of investments? Don’t think you would in the UK.

Maybe Tesla told him that the issue was fixed and he can use it again. Why do people trust auto pilot at such high speeds? It is still new technology. Let the autopilot park your car, if it makes a mistake the only bad thing that can happen is just a few scratches and in 5-10 years use autopilot on low traffic streets and then go to the highway. You can't expect new technology to be safe.

Spoiler warning. Article punchline ahead.

"The whole point of a dimension reduction model is to mathematically represent the data in simpler form. It’s as if Cambridge Analytica took a very high-resolution photograph, resized it to be smaller, and then deleted the original. The photo still exists — and as long as Cambridge Analytica’s models exist, the data effectively does too."

That's an eloquent piece of explanation of a very important point.
And apropos the discussion about privacy legislation, it's also going to be a very interesting point. Will the Cambridge Analyticas of the world be able to claim they have held on to no personal data, when strictly speaking the raw data has indeed been deleted after being used to create a derivative work that can for all important purposes be used to recreate the original?
Assuming I find out I'm being profiled and demand to have my data removed, will society grant me rights to have derivative forms removed or adjusted too?
I'm somewhat pessimistic that legal hairsplitting about matters like these will make enforcement very difficult.

Or are you saying your netflix suggestions are getting worse?

Mine are pretty good and have held steady for a while, at least in terms of my own preferences, though I also am probably using it a little less as I've got Prime and Hulu now as well, so there's probably less times I'm randomly searching through Netflix and finding nothing.

I was thinking how maybe industrialization in general led to the killing off of many of the larger and more rare fauna around the globe so would that mean that Africa following in our more industrialized footsteps, even if it isn't us directly guiding their hands in doing so, is still somewhat our fault for inspiring that notion?

People cite their distaste and dislike of American and European all over the world yet the vast majority of those places champion all things American or European / white, if only in things like food, music, entertainment, fashion, and lifestyle -- if not more / everything. I know it's not "our" responsibility after a certain point so I'm just being curious on a very "surface level" here.
> In my time there I've never seen Zuck really duck a question. He stands behind what his company does and believes in the mission, as do most employees.

Just this week he has ducked questioning by the UK parliament, and opted not to stand behind what his company does. A couple of weeks ago, when this story broke, he opted to just hide for a little bit, issue legal threats against the guardian and the NYT and see if the whole thing would blow over.
> "Could it have still had a market if it was able to be built cheaper?"

That's a good question, and the answer is no. The Ranger really was as cheap as it could possibly be. The engines are pretty bog standard, normally aspirated, 4 or 6 cylinders, iron blocks. The fanciest thing in them was variable valve timing. The 2.3l Duratec in particular was very cheap, fuel-efficient engine that got the job done, and in my opinion the best of the Rangers.

MSRP for the base-model regular cab 2011 Ranger was nearly $5000 less than the regular cab F-150. It really couldn't have been any cheaper regardless of CAFE. I think crash safety regs have a much greater effect than fuel economy regs. Just a theory of mine.
Which is why I’ve always maintained it was a very misleading name and would lead to dangerous accidents. Which it seems to have on a number of occasions.

Of course people may have abused the system if it had a more sensible name anyway. But names competitors use like Automatic Cruise Control or SuperCruise seem much more descriptive of the system’s actual abilities.
