If those 12 hours is working on a farm that you own, I think that produces a very different outcome in the long run. If you can see a buildup of improvements and a reduction of hours over the long haul. Build a shed or a barn, improve the well, build a fence to last, breed the next generation of cattle, plant an orchard, etc. Maybe these operations are hard to fund by themselves, but the popularity of farm-to-table consumption could help bring it back. Being a steward to the land can bring great meaning especially when also getting to raise a family in that situation.

This is sort the situation that a lot of video games simulate, so doing it in real life might just work.
Also, the current PDF permissions model is comically obtuse IMO. Acrobat doesn't even expose the permissions bits directly, rather each permission exposed in Adobe's UI represents various permutations of those permissions bits rather than a 1:1 mapping. It has to, because the design of that bitfield is nuts.

The semantics of the bits are described in ways that are very open to interpretation, and can be used to specify combinations of permissions that just don't make sense (example: allow content extraction for copy/paste, but don't allow content extraction for accessibility purposes, like screen readers for the blind). I suspect there are no two PDF parsers that handle that bitfield in the same way, and that it may not even be possible to implement support for it without baking in contradictions and unexpected behaviors (from a user's perspective at least). I'd be surprised if even Adobe's implementation handled it in its entirety.
Most morality is cowardice
If I'm following your argument correctly, you're suggesting that treating autism as a spectrum is really just lumping together people with actual, severe autism with people who are just more intelligent than average. That's not how it works. Autistic spectrum disorders come with issues with sensory processing[1], planning, actually eating, actually doing anything, social interaction, and a whole bunch more, for pretty much everyone as far as I can tell including the well-paid, successful software developers. The fundamental thing determining where someone is on the spectrum is how able they are to convince people they're "normal", for whatever value of normal is seen as most important. (This is a common enough misconception that some of the more politically active folks even had a hashtag, #SoHighFunctioning, mocking it.)

[1] More specifically, with handling sets of sensory stimuli that society expects everyone to be able to cope with. It's a somewhat open question to what extent "disability", in this case, means "different from what society expects". (Oddly enough, I don't think this even used to be part of the official diagnostic criteria despite being really common.)
My ex has a degree in biology, yet can't understand that feeding the kids box mac-and-cheese and pasta multiple times per week (because it is easy to prepare) is what's making them fat, not just the portion sizes. So yeah, what you describe is real. I'd take it one step further though - not only do most Americans not really understand the content of their food, but most can't cook. They have really no understanding of how to plan means, shop for meals, or prepare meals quickly. So then you throw in long working hours and commute times and they feel compelled to reach for food that is fundamentally unhealthy.
Ask HN: How to meet technical mentor?
I work at a small startup with 4 other engineers and we all have a similar level of engineering experience. I read a lot to learn, but I often find myself having questions that don't only have one answer. I would love to ask a more experienced engineer but given our team size there are few.

What's the best way to meet experienced engineers with whom I could start developing a mentor/mentee relationship?
Which seems to have stopped over the last 20 years or so.
each of us all have been single celled animals for at least a couple of seconds

That seems wrong to me because it conflates different identity concepts. That cell wasn't me, but more like a seed from where I was built. Actually, if I'm not mistaken, identical twins come from a single embrio that gets splitted, so with that reasoning both twins were the same person at one time. I don't think so.
It's a false dichotomy. The life spent doing farm work for 12 hours per day, forever, is not to be compared against the life spent in non-productive consumption of entertainment, forever.

The alternative is to spend one's days doing anything at all--whatever a person may find pleasing. That may include playing video games for 12 hours every day. It may also include injecting as much heroin as the person can lay hands on. It might also include writing out a 1000-page mathematical proof. Or breeding rats to have better bladder control and better responsiveness to humans. Or designing a near-space habitat suitable for supporting a population of humans indefinitely. Or deciphering ancient scripts. Or building a roadworthy vehicle from scratch. Or building cosplay outfits. That kind of life completely blows the farm work out of the water.

A lot of jobs only get done because someone has to do them in order for everyone else to live. Those jobs compete with the things that don't need to get done, but people want to do because they think it's challenging, interesting, or fun. Nobody thinks that a job that can be done by a stupid robot is challenging, interesting, or fun. Boring, mind-numbing drudgery does not give anyone purpose.

It's not that people are bad at generating their own world views. They are bad at reconciling the colossal dungheap of comforting lies that have been fed to them for most of their lives with the objective reality that is starting to sneak past it, as lines of communication start to route around the gatekeepers that have traditionally been able to control the spread of information. The confidence and faith were never deserved in the first place. The story that could have previously been quashed by a local news editor, before reaching a national or worldwide audience, can now be spread instantly via social websites, and so too can the unfounded rumors of a malicious gossip. Before, people had to trust their kings, bishops, bosses, and touts. They had no alternatives--believe my bullshit now, or wonder forever what the truth might have been. Now, they are faced with a whole world filled with story-tellers, and are forced to decide whether any given person is trustworthy or not. For obvious reasons, the rulers that were formerly trust-because-you-have-to were lax in teaching those subject to their info-control about how to detect falsehoods or think critically.

The institutions formerly relied on most people believing them when they told plausible lies. They will be forced to educate people in critical thinking, now that everyone can be a believable liar on the Internet, because otherwise people will be more likely to disbelieve when the institutions tell lies, and also disbelieve them when they tell the truth.

did a good job of producing fake wines that were both palate
pleasing and mimicked elements of the wine being counterfeited.

The "Sour Grapes" documentary was a case study in vintage wine being more psychologically concerned with labels rather than actual delicate details in taste and nuance, as cheap wine was sufficient in quality to please nearly every one of the clients. Even many of the experts and brokers were satisfied with the cheap mixtures.

This.

At least parentheses have a useful purpose and can even help you when writing code (paredit and the like). Semicolons are only there to help compiler writers.

It would be ok if they were allowed, but optional. How many times do you really have to write more than one statement per line?
We give our large breed dog Limited Ingredient (by Blue Buffalo) specifically because it doesn't contain grains and other irritants. Maybe I'm being overly cynical, but I'm concerned that General Mills ownership will decrease the quality of the ingredients, and we'll have to find another brand, which has always proved to be a tricky, extended process of trial and error, where the "error" leads to your dog losing weight and having diarrhea.
Did you try psychedelic drugs?

Ibogaine [1] has been found to be particularly effective in helping those suffering from addiction. Psilocybin has also seen research in this area with some positive results. [2]

No, that sounds about right. At the normal grocery store in my area, for example, cauliflower, broccoli, cabbage are $1.99/pound right now, celery is $1.49/pound. Asparagus is much more expensive, I think around $4.99/pound.

I cheat by shopping at the local Korean grocery store instead, prices are much cheaper but you have to sort through the produce to make sure quality is up to par.
From Ice to Fire: The Incredible Science of Temperature
Ask HN: Linux laptop on a budget?
I need a Linux laptop on a budget. Doesn't need to be fancy. Perhaps supporting 8gb RAM (or more) and the ability to put in an SSD. Working Wifi and Ethernet and sleep (close the lid and wake it again later). I am doing platform agnostic c++ development. I can't afford another Macbook Pro.

I have a Thinkpad X240, 8gb RAM and a 256 SSD. However Debian and Ubuntu fail to recognize the trackpad, Wifi, sleep, etc properly. Try as I might.

Any recommendations?
"Han is a social construct" doesn't change the fact that they operate as a de facto ethnostate that keeps foreigners out and their more phenotypically distinct ethnic minorities out of power.
It has a certain 2006-2007 vibe to it, from how I remember the last major economic expansion.
It may be true that these ingredients are available in certain markets for those prices, but that isn't accounting for a significant portion of the true overall cost of healthful eating.

Healthy food tends to spoil, and if you're not able to go shopping multiple times a week and have unpredictable availability for meal preparation, you're going to see a lot of spoilage. If 30% of your fresh produce ultimately spoils, your actual cost is 43% higher.

Healthy food requires a degree of planning and execution which takes time and focus. Finding healthy options which are appealing for 3x meals a day is a lot of work if you aren't happy with 1 or 2 standbys every day.

Healthy food is extremely hard to find on the go. If you don't have a kitchen at your disposal generally you are shit out of luck for finding something that is truly healthy. So for example, the quality of my diet is highly inversely correlated with the amount of travel I am doing in a given month.

Making unhealthy choices more expensive through taxes is extremely regressive for many of these reasons.
Not very "meh" IMO as obesity, and especially childhood obesity, is a national security issue.

How Long Should You Run Your A/B Test?
Absolutely.

I think people underestimate how much walking or physical activity they’d need to do to counterbalance the calorie surplus they have on a daily basis. You’d literally need to be fast walking for hours and hours a day. Cars don’t help, but walking for an extra 3-4hrs a week isn’t the major factor here. It’s the pound of cheese you had melted on everything, or the 24oz Cola.
Also, most languages have a wide diversity of accents. Spanish, for instance, has 18 dialects just in Spain (plus the latin american ones).
Because changing human behavior is much more difficult than just making people take a pill.
My only personal experience is in cities, but my home was never more than 20m on foot from my voting place. I also know that even villages with less than 300 residents have one.

We also have many thousands of voting booths, so waiting times are low. One hour is rare.
Yes, many jobs are like this. Nothing wrong with it, it just depends on individual devs if they are okay with it or not. We are just 5 devs in our team and our manager spends a good amount of time optimizing dev hours so he can get the most useful features out. If this means using external services then that choice always wins (assuming we can afford it).
Making sense of Linux namespaces
Fully agree. Just wanted to preface by acknowledging that not _all_ products are created equal.
Old communties have old words. Check some UNIX command names sometimes. C doesn't rename its operators either.

Renaming stuff every few years dosn't make it easier to learn.
I got counterfeit Hill's Science Diet cat food from Amazon. Their customer service reps refunded me but seemingly did not care whatsoever about the counterfeiting issue. Amazon's value as a marketplace dwindles to me day by day as they don't seem to want to deal with any problems (like counterfeiting) that would require skilled human resources without automation leverage in the short-term. I see where they're going from a strategic standpoint but it makes me do a lot less business than I otherwise would with them.
But McDonalds and fast foods are much more expensive than healthy foods like rice, beans, rolled oats and potatoes, onions (all can be had for less than 1$ per pound). They should allow people to purchase those foods, and maybe even publish a guide on how to stretch each dollar farther.

as i said before, Beans especially are very well balanced, super high in fiber, protein and micronutrients.
56% (22%+34%). Which is indeed lower than 70% but also note that the 70% is very unevenly distributed across states.
I'd be interested how the superior perf/watt claims holds in googles practical setup. The additional Networking gear and power supply losses and so on might make the difference less.

I'm also not sure how we can take googles word for the numbers, since they might as well be eating a less-than-ideal power cost to promote their platform. Any upfront cost will probably offset by locked-in customers later on.

I might just be a bit cynical though.

"most vegetables cost below 1$ per kilogram"

I haven't seen 0.80 EUR/kg in Germany for vegetables, so I wonder where you live. I've assumed vegetables are rather cheap in Germany due to very high competition. Lettuce is around $1.85 a piece, carrots are 1 EUR/kg or 1.50 EUR/kg when organic. Karfiol is 2 EUR/kg here.

The cheapest discounters (Aldi) are little bit cheaper.
A sweeping new bill targets California’s housing crisis
I'm curious about this. I lived in a predominantly Latino (mostly Puerto Rican) neighborhood of Brooklyn for a while a couple of years back. The supermarkets were full of fresh, cheap food, yet the customers (who were consistently overweight and often obese, including the kids) were piling their shopping carts up with terrible stuff -- sugary cereals (Froot Loops etc.), sugary drinks (sodas, fruit juices, Caprisun, iced tea), white bread, snacks (cookies, doughnuts, potato chips), tons of frozen microwave meals, etc. I never saw a shopping cart filled with anything healthy and unprocessed. And I realized that I was actually being very picky walking through this place. I had to ignore 90% of the stuff they stock their shelves with because it's unhealthy.

Places like Whole Foods have the same problem, of course -- it's also full of sugary drinks and cookies, except they're labeled "organic" and made with "natural sugar cane" or agave, or they're things low/no fat yogurt (containing more sugar than the full fat ones). You can get fat on Whole Foods groceries if you're not super picky.
I think it is important to diffirentiate between people who are born with overweight body and cannot do anything with it and people who would have normal weight but are gaining it because of unhealthy food or lifestyle. Sadly, the page doesn't have such a table.
I completely agree, but my thoughts are that it is biology in action -- people crave fats and sugars, and by themselves rice, beans, etc don't have much flavor. Or, the average American's palate has become so conditioned to sugar that they think those things don't have flavor. They have also been conditioned to think of meat as the go-to source for protein. Plus, frankly, there is a stigma of "rice and beans" being poor people food or even "ethnic" food in some circles, Ie: compare a meat / potato / bread heavy "traditional" American diet.
This isn't about recognizing omniscience not. This is about bad-mouthing someone who wrote a programming language that doesn't support multi-line lambdas.

(Bad-mouthing: "not at this level of of programming", "This is a really huge problem because only 25% of people are capable of thinking for themselves", with the implication that van Rossum cannot think for himself.)

Explicit in there is the view that one must program with multi-line lambdas in order to be at a higher level of programming competency. A view I disagree with.

Your account name is appropriate as this is sort of smug attitude seems common among Lisp fans. I think they see Lisp (or Scheme) as a jewel of a language, but feel themselves in the doldrums of the programming world. They can't figure out why others aren't using it, and decide that others must simply be sheep.

That's bad-mouthing as well.
I don't get this. You'll get just as fat with "healthy" food. People aren't skipping small portions of healthy food because it's expensive - they just don't want to eat it at all, or they want to eat enough of it to feel full and satisfied, which is going to make them fat.
I partially agree with you guys substaining that there were cheap healthy things, but for my experience they were exceptions. I could find very rarely vegetables at affordable price and at decent quality together. Or they were cheap, or they were decent. And a head of lettuce at 2$ is a high price. As exceptions examples, avocados were good and cheap.
Just when I was on the verge of leaving Firefox over UI issues.
I would suspect most kids learned to cook because a parent was home doing all the cooking, and when they got home from school they would be expected to assist with meal prep.

With both parents working, less time to prepare meals, we are raising a generation who on average has a lot less first-hand experience with how to cook, and certainly how to cook healthy balanced meals.
(1) I think we should all collectively agree to ignore the LSTM results -- without the model converging, it's impossible to say whether or not the bug that prevented convergence also affected speed. I can build an arbitrarily fast LSTM that doesn't converge in a few print statements. :-)

(2) Unless Google releases the specs to the h/w, I'd argue that cost is our best proxy. But if you assume that both Google and Amazon want to make a profit on their cloud rentals, it at least gives us a way to get to something we can normalize to (the V100's list price is public, though who knows how much Amazon pays). And, given that you can't buy a Cloud TPU, the price Google charges really is the meaningful answer. It doesn't tell us about fundamentals, but it's the right answer from a consumer standpoint.

I think it's a fair bigger-picture question to ask how we fairly and informatively benchmark cloud-only services in ways that we can not only get consumer-oriented price comparisons, but also learn from the underlying technical choices. The longer-term answer is that we beg Google to write a paper about TPUv2, as they (surprisingly!) did about TPUv1 -- because without that, we just get black box numbers combined with informed speculation based upon glossy board and heatsink photos.

btw - the best current source of specs about TPUv2 was Jeff's NIPS talks: http://learningsys.org/nips17/assets/slides/dean-nips17.pdf

Which mentions a few details like 16GB HBM per chip with 600GB/s memory bandwidth.

(3) I agree completely with you that the comparisons are hard. I'm very glad the authors of the blog post are listening to the feedback they're getting here -- on the LSTM, on batch size comparisons, and about precision and being clear about which things they're measuring.

(Reminder disclosure: It's awkward talking about Google in the third person since they pay me part time, but I'm trying to take this discussion with my academic hat also. This nested series of disclaimers is an amusing commentary about how small the machine learning + systems community is.)
IDK, I feel like this is the kind of slightly smug reasoning that's seen lisp get passed by. Just because I believe the factory-made, cheap, and standardized building blocks are a better medium than your artisan homemade clay blocks doesn't mean I'm just a dumb pleb churning out junk. I just have different values than you.

I've spent lots of time crafting the greatest macros and trying to deal with missing/half finished/supported libraries in lots of languages, but at this point I just want to build and spending time on those details isn't worth my time, it doesn't help me make a better product.

It turns out that declaring yourself the greatest and resting on those laurels can lead to myopic overconfidence. There's very little at this time that lisp is actually the best choice for, unless you have very limited reliance on outside libraries, and even then, other languages have different tradeoffs.

Real artists are fewer in number, but those will want clay instead.

This is incredibly pretentious and might not match reality.

Yeah, all of those are single serving prices that you're looking at, and only the onion (and I guess lettuce if it's not romaine) is actually a vegetable. Potatoes are starches, the others are fruits (with higher sugar). They don't list much in the way of vegetable prices.

But, even given that; I can buy a head of lettuce for $1.40. Okay. Or, I could buy an 8 pack of little debbie snack cakes for the same amount. 5 servings of lettuce that has nearly no nutritional substance, and that I have to combine with something else anyway to make it palatable...or 8 servings of convenient, enjoyed food.

If I wanted crunch, I can get a giant bag of tortilla chips for $1, too. Why would I buy a head of lettuce for 40% more, when it takes more work, and more ingredients inflating the price even higher?

By that rationale every foreign language is broken, and, maybe more pointedly, every language but Chinese (or possibly Spanish) is broken and needlessly difficult to learn.
