You can run electric vehicles on solar, wind, hydro, natural gas, coal, nuclear, oil, jet fuel, etc. The delivery mechanism of energy for transportation is separated from production and competition in the production space will continue, despite lots of incentives distorting the marketplace.

Gas vehicles run on gas which comes from oil, or recently some combination of food, but mostly oil. I welcome the disruption of this industry.
> It's far from clear to me that any beyond a small percentage of people generally, but perhaps Americans in particular, have the capacity to become lifelong learners.

This is very much incorrect, although I imagine that there is an abundance of anecdata that supports your hypothesis.

First, most people are learning and are developing cognitively for their entire lives. To get some simple data points, ask anyone who has had kids or who has been/stayed married -- these are fairly intensive ongoing learning experiences. But maybe it's different for formal learning...

For simple data points on that, I encourage you to volunteer your time at a retirement community to teach basic tech to the residents. Teach them how to use apps like Facebook, FaceTime, Skype, or even Snapchat with their family members (esp. grandkids). They will LOVE it, and they will definitely learn. Of course, some will be more curious than others, and some will learn more quickly than others, but the capacity and motivation is there.

I agree with your point that motivation is sometimes an issue, but there are a variety of reasons for that, and some of those reasons don't reside with the potential learner.

> I feel that the answer is basically "let's fix our education system," which I -- again, perhaps overly pessimistically -- believe to be politically impossible.

This is a really good point, but I think that there is a lot of potential for disruption in the education sector.

To me the most interesting thing is not just a fully-simulated video but a fully-simulated interactive scene using VR or AR, and that is obviously an even bigger challenge. I don't personally think that either of these objectives are even close to being just around the corner, but I do think we are moving toward them. I have no idea how many additional orders of magnitude in computing power would be necessary to create a convincing simulation. The journey in that direction is a fun challenge though, right?

I did just read your previous posts, and it sounds like you have a pretty interesting history of working on all of this stuff.
I cook most of the meals as well. I do 90% of my shopping at traditional grocery stores, and use the weekly farmer's market as a way to experiment over the weekends. At least in SF, they're high quality and typically have a wide variety of things I wouldn't find (or buy) in grocery stores. We have a few kids, so it's nice to have a reliable menu throughout the week, then do something fun like a smorgasboard of oysters, salads, bread, and cheeses for lunch on a Saturday, crab tacos for dinner, and omelettes the next morning. The constraints enforced by seasonality and the availability of atypical ingredients is refreshing.
Bay Area and Los Angeles (Echo Park) both have farmers market in spades that blow away the local grocery stores.

You need to look for local farmer's markets, not the faux-distributor's ones. I think what you need to know about Farmer's Markets is that you must buy (can only buy) in-season produce. While this might disappoint the regular grocery shopper who is used to bad tomatoes in December, to the the chef, its a great delight to be able to pick from only the right season's produce.
5 Things You Didn't Know You Can Do with Mattermark
Honestly most people I've met who are depressed are just mentally weak people experiencing first world problems. Yes there is that 5-10% that truly have a reason to be, but that's a very small minority.

Depression is not outside of your control. This encouragement of that kind of thinking classifying it as a "disease" is what keeps people depressed (and makes doctors money).

Was reading a book by a now successful guy who was suicidal all throughout his teenage years. He said that feeling suicidal was one of the best things to happen to him because it gave him this risk-taking attitude to just make the bold moves to turn his life around, because if things didn't work out, he could always kill himself.

Honestly it's unfortunate that this is considered too touchy a topic to talk about. We'd have less suicides if we could openly talk about it, and maybe you're committing the sin that you're accusing me of.
One of my thoughts as well. Also _hallucinations_ by Oliver Sacks.
My understanding of Brutalism (as it related to buildings) is that it is supposed to feel daunting, uniform, and unashamedly utilitarian while being (almost surprisingly) highly usable and subtly beautiful (to certain tastes).

So I would say a 'brutal' web page would be a plain Apache file index. Basically the opposite of what we see here.

To be honest, I just copied that from some other site, because I can never remember how to pronounce that name.

I guess I would just spell out names the given audience is likely to mispronounce - although you could argue to do it with every name, like one newspaper always mentions who a person is, no matter how famous ("bla bla, Donald Trump, president of the United States, bla bla Joe Schmoe, plumber from Virgina")

As I mentioned below, the only technique that produces effective results is if you mix actual, real footage with CG. It's true that people can't spot the CG in that situation, but that's different from the discussion of how to create fully-simulated realistic video.

I'll give you a simple way to defeat any question of whether we know how to make something look real: What does it mean to multiply two colors?

If you chase down the logic, the true answer is "It's meaningless. It just happens to be an approximation that looks good in most cases." But it has nothing to do with how light works in real life. Yet every engine multiplies colors because the alternative is too computationally expensive -- and it still wouldn't produce realistic results because we don't source our art from real life. Artists typically control the content, and any art-driven pipeline is doomed to look pretty good but not real.

I ended up cancelling and vowing to never go back to their service after they didn't credit one of my "come back" coupons correctly. Not that it was the biggest deal, but they deliberately were doing something other than what they advertised and were completely unapologetic about it.

If it won't work small it won't work big. First learn to walk. If I can overcome all the challenges and there is a sufficiently large market for the end product and when all the costs (energy, for instance) have been accounted for there is still a business case left then this might be worth it. But there is a ton of work to be done before you could begin to answer those questions. For now it is a fun project and I'm trying hard to keep it that way. I've been approached by some of the larger bulk resellers that would love to get rid of the humans they employ, none of them made a good enough case why I should partner with them or even seemed to be nice people.

The general nature of neural nets for sorting and classification I think is well recognized in industry and there are many companies that are capitalizing on this (and have been for some time). I highly doubt I'm doing anything original in that sense.
There's a company at Georgia Tech trying to automate sewing[1]. Although it's hard for non-technical people to believe, sewing is one of the most difficult AI challenges and is far from being totally solved. We don't even yet have robots that can just fold laundry.

In the US, the military is only allowed to buy American-made products. That means they spend many fortunes on sewing that's done domestically. This company thinks that if it can automate sewing, it'll have an instant, massive customer (the US government) and can take over the world from there.

For people watching for the global automation apocalypse, this is perhaps more dangerous than any self-driving technology. If it becomes widespread, it'll likely cause a few countries to collapse economically.

"This is an unpopular opinion, but nobody knows how to make anything look real."

Unpopular? By whom? Computer graphics is a crafty bag of tricks sprinkled on top of very concrete linear algebra and computational geometry.

That said, it's actually hard to create appealing images just in plain old photography, so anyone thinking computer graphics would facilitate any artistic aspects is in for disappointment.

The math needs to work, but you need artistic talents to make anything look good/real.
I find it interesting how "Homer" has experienced a constant, steady decline in usage over time.
It's fairly easy to trick yourself into hearing voices: as you're going to sleep, picture yourself watching a newsreader. Keep watching them talk. Eventually your brain starts to switch to sleep mode and you actually start hearing something. (Well, you might fall asleep first.) If you're conscious enough it'll surprise the heck out of you and then the voice will go away.

Given how easy it is to pull this trick on yourself, I'm not entirely shocked that some people find it possible without conscious effort. But I think the content is rather like dreams: sometimes it's just nonsense, sometimes it's like that idea that comes to you in the shower, but always part of your brain processing your waking experiences.

Interesting. So maybe it's a Baby Boomer phenomenon? Wish the data went back further, doesn't look like the Census started monitoring this before 1948. With some Googling it looks like federal home-ownership assistance efforts (either through providing subsidized housing or tax relief) started as far back as the Great Depression. Maybe people just wanted houses and prior to such programs it was unattainable for most?

Looks like a good topic for a book for anyone who has the time. I'm sure it's a confluence of several factors. :)
The current reality is worse:

ClojureScript, Elm, Elixir CoffeScript, Babel and Emscripten all compile to Javascript and ship their own Runtime.

Given the complexity of Javascript it is not a good fit as a compilation target.
Something I've always questioned is why certain jobs in the United States are expected to be tipped but others aren't:

Why does a bartender at a bar that isn't very busy who simply pours me a draft beer out of a tap deserve a dollar when a guy making burritos at Chipotle during the lunch rush who can't take a break for 3 hours straight doesn't get any tips? I've had bartenders hand me a can of beer for 2 dollars, I come back 20 minutes later and ask for another and they say "ok but I'm going to charge you extra because you didn't tip".

If I ever did that when I worked at any fast food job I've ever had I would have been fired.

Either have a tipping culture or don't, but don't have social punishments for skipping tipping on bartenders or restaurant waiters but then don't tip me EVER when I work a different minimum wage job that can be just as hectic.

Many bartenders and waiters take the approach of tipping constantly at other low paying service jobs, which is very admirable.

But others will berate you if you mention that you don't tip for every drink at a bar while they themselves see no hypocrisy or problem that they aren't tipping low paid workers in other industries.

Before someone mentions that some of those tipping jobs can have pay that's less than minimum wage - remember that if tips don't make up the difference then the employer is legally required to pay the minimum wage for that shift.
> for their $60 per week to get 6 small portion meals I can buy over 2x that number of meals shopping at my local store, + snacks and other household items

The value proposition is, primarily, saving time shopping, meal planning, and portioning-out ingredients.

Whether this is sufficient to justify the cost depends on how you value your time, and whether you find value in spending it on those a activities.
A nice analysis, and it shows how SQL makes it easy to quickly explore data.

However, it seems like the plots of the results of the queries were done manually by writing some code to make each plot.

I can't stop but mention that using Apache Zeppelin Notebook [1] with Postgres interpreter for Zeppelin [2] (Spark SQL should provide comparable analytical capabilities as well, but this comment is not about it) it is possible to show graphical representation of query results without writing a single line of code.

There are farmers markets where you have local farmers come together as part of a co-op or some other organization and sell their produce, and then you have "farmers" markets which are basically outdoor grocery stores that sell the same things in your big chain grocery stores.

You have to go to a "real" farmers market. The best way to tell is check out where all the delivery trucks are and read some of the boxes. If you see "product of California"" or "product of Mexico" on many of the boxes and you are in a farmers market no where near Mexico or California, you are at an outdoor grocery store.
In that case the local economy would benefit from the decrease in $Y, which is an example of what GP described, not anything going the other way.
Ironically, part of their pitch to customers is "By cutting out the middle man and delivering ingredients at their freshest."

If that’s actually the pitch, I’m...astounded. Unless they’re in the field picking this shit themselves, they’re the very definition of “middle-man”. If they want to make themselves feel better, call it “value added reseller”, but you’re still a middle-man.

And maybe they are out there, in the field at the crack o’. But I have my doubts.

I like the concept. At the moment I use contentful so non technical people can edit their static site and don't have to worry about running a server (and especially keeping the software running on it up to date), but I'll probably switch to NetlifyCms (or hopefully emerging competitors) when they mature a bit.

The thing I like the least at the moment is form submissions.
> You may be over analyzing it.

I'd say it would depend on the tone and body language in which it was said; the words themselves, "where have you been?", could easily take on multiple meaning depending on inflection and delivery.

It could be small talk, and maybe it might be a cultural difference, but the words alone (without taking inflection, etc into account) sound accusatory to me; if they were really wanting to know where their coworker had gone to lunch, and whether it was any good or whatnot, I would think they would phrase it closer to what you wrote, rather than what the OP has stated.
> The reality is this: alcohol is worse than water and alcohol is bad for you.

Except if you're at risk of cardiovascular disease as I mentioned. Water cannot save you there. Why can't you agree? You're ignoring every opposing argument in this thread and making false statements like "alcohol has no benefits over water period".

> I’ve often wanted to sit down with Mark Zuckerberg and argue with him about Facebook. It is premised on the notion that "connecting everyone" is an unmitigated good.

This isn't the author's major point. But worth noting Zuckerberg changed FB's mission recently to "Give people the power to build community and bring the world closer together."

Said Mark: "Connecting friends and family has been pretty positive, but I think there is just this collective feeling that we have a responsibility to do more than that and also help build communities and help people get exposed to new perspectives and meet new people -- not just give people a voice, but also help build common ground so people can actually move forward together."

You may use both of the syntaxes; but the former allows to easily inject JS variables directly, rather than by interpolating strings.

For example:
var userParagraphMarginSetting = '5em';
styles={{ marginLeft: userParagraphMarginSetting }}

Against:
var styles='marginLeft:'+userParagraphMarginSetting;
styles={styles}

It sounds like your existing hopper is reliable but slow? If that's the case, could you just make two (perhaps somewhat smaller) hoppers and merge their outputs?
I used to think that there was no point in going to a farmer's market. But I went to one for the first time in Columbus, Ohio and bought some blackberries. I remember very distinctly waiting for the bus to go home, eating one of the blackberries, and thinking, "Oh, so this is why there are farmer's markets."
I haven't tried Blue Apron or any of Amazon's meal delivery services but I do use one of BA's competitors. I don't have the time to plan multiple meals a week for every week of the year. I don't want to make one big meal at the start of the week and eat leftovers for the rest of the week.

Furthermore fresh ingredients get delivered to you in the right portions. When I've done this in the past I end up with way more ingredients than I need that end up getting thrown out.

These services also give you a way to quickly try a meal out and decide if you like it or not to make it again in the future. If so you keep the recipe card.

There is absolutely value in these meal services.

I think it's likely that Amazon and Whole Foods can replicate this process though and they will be able to drive down costs due to their distribution power and economies of scale.
