Not OP but I've also researched this topic and settled on an iqair filter back when I lived in China. I did borrow a particle monitor and the drop in the number of particle was flagrant when turning it on.

Subjectively it also did a lot to improve the air in the house... I'm not sure that something like an iqair is needed in a place that isn't as polluted as China (we sold our air filter when we moved out)

My theory as an outside observer has always been that [white] Americans are like salmon. They are born in the suburbs, they move to the city to find mates and build careers, then they move to the suburbs to have children.

As an American-in-training I too would be terrified of having a kid in a place like San Francisco. Ain't nobody got money for that.

That said, when I did live in the suburbs for a while, I found it to be depressing and miserable. But I grew up in a small city, 10min walk from as downtown as it gets, so I'm biased.

I thought I’d try my hand at a small collection for Hindley–Milner.

[Var]
When given a var’iable X
that’s already in the context
with some type called T
then obviously
that T is the type of that X.

[App]
Encountering two terms abreast
where the former’s a function, you test
that the function can take
what the argument makes;
its result gives the type of the rest.

[Abs]
The term “lambda from X to E”
infers as the type A to B
if the context, extended
with X represented
as A, says E typechecks as B.

[Let]
The type that is lastly inferred
when a term’s bound with “let” to a word
—and the body can cope
with that name bound in scope—
is the type that the body incurred.

[Inst]
If you don’t find it too esoteric
and you happen to have some barbaric
too-general expression
then at your discretion
you can choose a type that’s less generic.

[Gen]
If the type of a term could abide
any type that a user supplied,
and the name occurs not
free in context, you’ve got
a type var that’s forall-quantified.

The meter could stand some improvement, but nobody expects limericks to be perfect.
I don't understand. What do you mean by 'loose' internet connectivity?
I never knew much about that subculture. Is it bad that those people look rich to me?

They have cars, and a place of shelter that they own. They have family. I scrape by paying rent and put food on the plate, and ride a bicycle to work every day. I still can't afford to learn to drive. Parents won't support me, although I spend 3 months of savings to buy a plane ticket to see them each year, using the 8 days of holiday I'm offered. Most of my friends and colleagues earn half of what I do. The idea that someone could earn 30,000 USD in Alaska in only a few months sounds unbelievable to me. The trailer lifestyle would be an upgrade from working for a tech company in Asia.
I agree with you if you're also not taking any actions. However tech workers are building powerful tools that could be abused if the software or data got into the wrong hands.

My grandfather ran a store that my uncle took over. No pennies, no tax. Everything was priced as marked. End of the day, count up the register and write it in the log. end of the month calculate how much came in, multiply by sales tax, and send a check off to the state.

Maybe they're cheating. IMHO, most of that cash register discipline is because the owner (or his immediate family) isn't running the register.

Im sure you can get away with not paying taxes for a while, but if you're going to have a generational store, you've got to be honest.

Technical controls are cool and all. When you can just look over and see you need more cans of soup, when you implicitly trust your employees, and you're not looking to make a quick buck and run away, they're just a lot of work for not much value. Scaling has a cost.

Same. The problem is that RxJava shoehorns FRP into, well, Java. A language built for it (Haskell, et al) might have just as steep a learning curve but probably a higher plateau.

People buy tickets to place bets on the exact minute the clock will be stopped. The closest bet wins, and if there are multiple bets on the winning time, the winners split the prize. The prize has been over a quarter million dollars in recent years.

Wow! They took out all the things that made the surface useful for college students and then marketed it towards them.

A surface pro/book is a fully functional laptop which could eliminate the need for carrying around large piles of papers/notes.

Take that away and what you have left is just a regular laptop (with a touchscreen that's rarely used).

There's probably a market for this but it's not going to be college students.

Etsy gets multiple thousands of vendor sign-ups per day and needs a dedicated team to filter out vendors that attempt to game the marketplace by flooding it with thousands of listings for cell phone cases and other junk.

A lot of it is driven by Chinese middlemen and get-rich-quick schemes that are more than happy to burn the marketplace to the ground if they can make a buck in the process.

The challenge is that in the beginning the revenue is good and it's hard to say no to revenue when you need to beat the street every quarter. It seems so manageable at first. But unless you've lived its very hard to wrap your head around that you've planted the seeds of your own destruction.
Gruber asserts it's the opposite:

Even among pro users, notebooks are by far the most
popular Macs. In second place are iMacs. The Mac Pro is
third. Apple declined to describe the Mac Pro’s share
of all Mac sales any more specifically than “a single-
digit percent”, but my gut feeling is that the single
digit is a lot closer to 1 than it is to 9.

The author isn't attempting to romanticize these people; he even goes so far as to call these people helpless. From the outside in, you have to wonder, why there is such an opioid epidemic in WV, why these people live in small dumpy metal boxes... The author's grandfather continued to love a woman who shot him. The author's father grew up in a one room shack afraid to fall asleep because rats would gnaw off his feet, was forced to hunt for survival at the age of five or six and eventually had to live with his Aunt. Despite that, his father would not talk ill about his father; he loved him.

The whole point is to help people from the outside looking in understand. It's easy to say these people are ignorant, these people are naive, but to fail to even see things from their perspective is just as bad as them failing to see things from yours.

This is a pretty abrupt context switch after coming from the article on stereotypes, trailer homes and rural folk that's on the front page right now.
Its interesting to see the path Etsy has taken. IIRC, around 2007 or so they closed all of the 'vintage' shops because they weren't handmade. They quickly went back on that and restored those accounts. (In 2014 they also tried removing 'vintage' from 'browse', which resulted in a lot of backlash.)

Its a shame to see them relaxing the standards over the years. In 2007 their blog even acknowledged the mass-produced items and the lack of support for these products [1]

> I really dont think bitcoin is a viable currency for mainstream use.

Bitcoin is not a replacement for paper money, but for digital money. Only in developed countries, digital money is in mainstream use. Outside, the majority of people are "unbanked".

The problem with digital dollars is that government and banks can create them out of the fricking blue. They effectively do that -- all the time actually -- while in the process debasing and devaluing the dollars that you are holding.

I got many of my bitcoins a few years ago at $250/btc. Now they are almost $1500/btc. I think that bitcoin is a very viable digital currency. Seriously, I am not willing to exchange them for liberally-printed digital dollars.
I like this. It also reminds me that I should make more use of my G keys on my Logitech mechanical keyboards.
Another possibility to "both positive and negative are important" is that in some sorts of situations positive is more important and in some sorts negative is more important.

> After the war, they were taught to redirect their devotion to the nation from its military expansion to economic expansion. They were constantly exhorted that they were a homogeneous people and superior to all other Asians, and superior even to the whites. To establish their national position in the postwar world, they should not be very concerned about individual well being, thus should not mind the high cost they have to pay for consumer goods that cost less abroad.

It would be nice to have a shred of evidence for claims like this. "Constantly exhorted ... that they were superior to all other Asians" is almost certainly pure fiction.
They operate like a music studio or production company. They take applications from (or scout out) likely-looking 'undiscovered' artists / entrepreneurs, and offer them an advance / venture capital, along with advice and other resources, to create an album / product, in return for which they take an interest (shares / rights) in the resulting product.

The details vary slightly (as the other response said, music studios typically take the rights to the album in exchange for royalties, rather than directly becoming a part-owner of the artist) but the basic model looks very similar to me.
Ask HN: Why don't Universities start/own more companies?
It occurred to me recently that Google/Apple/Amazon/IBM/etc. have armies of scientists that innovate, try to understand it fully, control it, and then design it to be used by the masses. Why don't universities like Stanford, Berkeley, Harvard, etc. use their tremendous funding (endowments + tuitions + licensing + etc.) to do the same? I understand that some currently do own at least part of some companies in some cases (I.e. Stanford with Google), but why don't they incubate and own companies entirely? Some certainly have both the business and science talent, wouldn't the next step be taking some risk and using their army of professors and business leaders to build and own companies in house?
It's not the "pro" market: Apple considers ~30% of their user base to be "pro". You wouldn't ignore that.

Now, within the pro market, notebooks are far-and-away #1, iMacs are #2, and the Mac Pro is #3 (and is described as "single digit" sales percentage). Would you care about 1-3% vs. the other 97%?

The problem is that that 1-3% are probably very vocal and the "trend-setters".

Unless a market has low barriers to entry (startup costs, materials availability, skills availability) it will trend towards monopoly or oligopoly. The economies of scale gained as a market leader grows ensures this.
This is amazing. It should even be possible to have characters traverse obstacles differently depending on their in-game skill level.

Imagine this system used to implement rock climbing. The player is simply pressing the "W" key to go up, but depending on their character's skill level the speed and manner in which traversal occurs could be very different.

I really hope Bethesda is paying attention to this, because open world games could use it more than anything. In Skyrim you climb mountains by mashing the jump button. Far from ideal, and tends to break immersion.

The tech could even be used to power melee animations some day, perhaps entire fighting styles.
I pretty much don't turn on WiFi unless I'm doing streaming audio or video.

Having wifi on is pretty bad for my battery life in general, because I'm moving around a dense city and my phone constantly is trying to connect to open wifi hotspots that are going in and out of range. Keeping it on only extends battery life if my phone is staying in one place with good wifi.

> Do you use a reverse osmosis system? Any recommendations?

I got a watts premiere from costco years ago and it works ok. incoming water is around 500ppm TDS(total dissolved solids) in an area that has very clean tap water and comes out about 20ppm(bottled RO can get to around 0-2ppm with the industrial filters) with my water pressure. you need to change the filters once a year or so and I get them on amazon for like 20 bucks or so and a cup or so of hydrogen peroxide to sanitize it. you need to change the membrane every 3-5 years or so depending on water quality and that's about 40 bucks on amazon right now. Whichever way you go, you will want a multi stage ro system with a sediment, carbon (I can't recall which of the sediment or the carbon is doubled up but one is) and polishing carbon filter post membrane.

I used to work on ultra high purity water systems for pharma so I probably care more about water quality than most consumers. If you have more questions ask away.
Simple code tutorial for image recognition using Keras
How I see it, Lisp 1.5 was Lisp, but as time went on and many 'versions' of Lisp for different systems with different capabilities came into being, there was no longer really a singular Lisp. Then there was a great unification that spit out Common Lisp, and that became Lisp. So if Lisp 1.5 was released today as something new, it wouldn't be Lisp, but merely another Lisp-like. It's too different. No one today thinks that if you drop "Lisp" in a conversation you really mean Lisp 1.5. (Maybe if you write it as LISP...) It's either going to mean Common Lisp, or maybe a reference to the vague Lisp Family. I don't think Lisp will ever be synonymous with "Scheme".

Maybe you'd appreciate some Lisp history, to also answer your question about "what other dialect[s]"?

Yeah, what we need is a patent system that only gives 5 years, maybe some lower barriers in terms of how it's enforced. Maybe where a jury is asked 'does this feel like a knockoff of what the patent was generally describing or does it really do something new.' The risk of going afoul will be enough to keep people innovating.

I'd really love to see a common sense approach to patents.
