> Many airbnb are not people "renting on a weekend when they go on holiday". It's a mini hotel. The former I don't mind, the latter should be taxed out of existence.

1. What percentage of Airbnb users belong to each category? Why do you ignore the former and hope 'they all get their fingers badly burned when rates rise'?

2. You still have provided no argument as to why the latter should be 'taxed out of existence'.

> Your comment about groceries is dire. Production of food is elastic. Production of land is not.

This is irrelevant to the point you and I were discussing, namely, that restricting the supply of something will not magically lower its price. It works just as well with any other supply-inelastic good or service.

> Taxing those who simply try to be middle men to be, yes, a rentier is a good thing.

Can you clarify what you mean by 'those who simply try to be middle men'?

> So many bad comments on HN that fail to understand elasticity and how prices are set. I'm off.

1. It's a bit ironic for you to make this accusation when you're literally advocating for taxing an entire economic sector 'out of existence'.

2. I made no comments about elasticity of supply. You did.
Perhaps so, but in this case the solution is one that's already well known (that you can express trig functions exactly when you're dealing with right triangles with integer sides).

If you want to do some computation involving a given angle, you're not likely to have the luxury of picking the angle that makes the computation easy using rational arithmetic. The sine of 45° is an irrational number (1/sqrt(2)).
A culture of bribery undermines a society. It's the kind of moral decay that plays a huge part in holding back developing countries: http://www.thedailystar.net/op-ed/cost-corruption-111523.
On the flip side, as someone who's tried to change stacks or IDEs or other software a few times, there's something to be said for already having momentum using existing solutions. Sometimes alternatives can be a little better, but not better enough to justify the time/energy/etc costs of switching. And more often than not, alternative solutions have their own flaws too. I tried three times in the past week to switch my portfolio website (https://sdegutis.com) to using Jekyll or Metalsmith or Hexo, and each time it just didn't prove any better than my own hand-rolled Node.js site generator, and in most cases, it was definitely worse in some ways, at least for the specific requirements I had. So switching tools can be good, if it's legitimately better in some way, and not worse in any other ways. But that doesn't isn't the case as often as we'd like to hope.
> Jennifer and the many other programmes like her are examples of a “voice-directed application” — just software and a simple, inexpensive earpiece. Such systems have become part of life for warehouse workers: a voice in their ear or instructions on a screen tell them where to go and what to do, down to the fine details. If 13 items must be collected from a shelf, Jennifer will tell the human worker to pick five, then five, then three. “Pick 13” would lead to mistakes. That makes sense. Computers are good at counting and scheduling. Humans are good at picking things off shelves. Why not unbundle the task and give the conscious thinking to the computer, and the mindless grabbing to the human?

I remember reading in Scientific American a few years back, about a study that was very striking and against common intuition. In manufacturing, robots had overtaken humans at a particular task by a long shot. They were able to perform the completion of assemblies much quicker and with higher accuracy; humans coming in afterwards and applying finishes that required small hands, light touches, or hard to explain measurements.

Robots > Humans. Humans finished what robots couldn't.

What wasn't foreseen, however, was that there was an additional step to shave off even more time. Given some artificial intelligence, the robots could actually tell the humans when, and how, to do assembly during and as part of the assembly process. The robot figuring out the most efficient assembly, and instructing the human to do what it couldn't, was a third step of assembly efficiency not foreseen.

It turned out:

Robots + Humans > Robots > Humans.
That's kinda the point. We need rules because Nazis (and Tuskegee, etc.) but it's not clear we need these rules about pen vs pencil.

The product was built using Django and the author is a big Django contributor.
You do, however, the MDs do not. And if they are not using MDs, that is insane too. That they are injecting something without IRB approval is nuts as is, that any licensed MD in the US would do so is doubly crazy and I would like to never be practiced on by them. The medical field is a different beast than, say, putting on an aftermarket car-horn or putting super instead of unleaded into the gas tank. The vast majority of people, including nurses and other MDs, have no idea how a specific medicine works or the complexities therein. Docs are required to help them, not to hurt them, we've thought so for thousands of years. Yes, many may say that they are helping the people, but the large majority of other MDs, via the IRB, say that they are hurting them. I'm gonna go with the IRBs here and say this is crazy stuff and sets a very dangerous precedent.
Django have an "engineering is important" philosophy so developers attracted to Django have a similar mindset. In this case they're showing how despite superior engineering and a proven market is insufficient on its own - the start up required more effort in marketing, sales, financing.
Old people vote :)
Sure, but the title is link baitey. It suggests Django had an impact on the failure of the company when in actuality it has absolutely nothing to do with the outcome.
yeah, they probably saw that coming a mile away... :)
This is building a business 101. I still feel it's disingenuous to begin this long winded post with the connection to Django.

As an aside, I'd argue that any modern web framework with decent community interest also attracts the same "engineering first" individuals.

If you're betting the farm (read: assuming your progressive choice is going to do anything more than speed up dev time) on your choice of web framework you're definitely doing it wrong.

The software you create is a means to an end.
And the reinsurance folks seem to say that there is absolutely no evidence that there has been an uptick in these big disastrous storms. People are constantly thinking of global warming, so when they see a storm, they say "Aha! Global Warming!". Of course there have always been hurricanes, and human perception/remembering is not a replacement for statistics and math.

From Warren Buffet (One of the largest insurers of this type in the world) "...climate change had not up until then [2016]
produced more frequent nor more costly hurricanes nor other weather-related events covered by insurance.""

> i am not sure how anyone with a clear conscience could ship a device which works by accident

LOL, welcome to enterprise level "Ship now, the service contract gives us at least a few weeks to work out the kinks" hardware, where understanding how the whole system actually works is a luxury most the engineers don't even have.

Kudos to them for giving it a good shot and continuing to look. A lot of times, unless you have money or clout to throw at some of the component originators, you're out of luck if you want real answers. The few engineers that have them are probably so busy that to devote them to figuring out what's really going on isn't worthwhile for the companies without some higher level intervention..
> I've never known a USN or USCG vessel to deviate from those rules out of courtesy

Ah, not out of courtesy. More out of just pointedly staying away. See, on most USN ships, the OOD has to call the CO if any ship's CPA is within 5 miles, or some other parameters are violated (you deviate from course more than 10 degrees, more than 10 degrees rudder, etc). So the game is to use all the leeway you have to avoid any situation that would require the captain's attention. So, at least in my day, we kept ourselves engaged at night that way.

The Fitzgerald's situation, I can at least understand why the CO wasn't on the bridge. For the McCain, where was the CO when the ship was in the Strait? What else on that ship could have possibly been more important than navigating the Strait?

>>That is, even though Alexander had a long wait time just to hear responses, there are expensive services you can use that make all that wait time and pushback from hidden rules disappear, so you don't see it as a problem.

You can make the wait time disappear. In my experience, you cannot make the pushback disappear. I've been scolded multiple times by our IRB for improper and too-technical language in our Informed Consent forms, amongst other violations/gaffes.

IRB is poorly-designed. Should it go away? Sure, in its current incarnation, yes. Will it? Like anything government + university designed, there is a snowball's chance in hell that anything with that many moving parts and bureaucracy will ever die a true death.

The private markets designed a workaround for this and they are accepted as every bit as good as the university and medical IRBs.

As far as "expensive," your time is valuable if you are a scientist. You should act accordingly. The IRB fees we pay are less than 7% of the fee it costs to publish in major peer-reviewed journals, which is another racket that is propped up by the government + university complex. So I don't consider it expensive in the least. (It is well under $500, to give you a hard number.)
It really needs a TL;DR because it's all buried in so much fluff I didn't understand why. (I understand the rest of you all really enjoy that and wouldn't call it fluff but I'm not an audio engineer).
Because of the power decrease as you go up the overtone series, I'd suspect that being able to hear higher frequencies wouldn't cause very much trouble. However, the ability to hear higher fundamental frequencies would surely change harmonic theory! This is assuming that our pitch perception of high fundamental frequencies increased accordingly.

It varies widely. We have ~300 users, 30 projects, probably on the order of ~20k tickets. Performance has been up and down, occasionally things slow way down and we have to file a ticket and then they come back with some excuse about re-indexing or relocating the instance. Normally it's pretty acceptable, but it feels like there are a ton of a variables that go into its performance day-to-day and minute-to-minute.
I'm torn. I like the essay, but it is just as excusable to know that using people to act the part of androids necessitates them being extra life like.

Similarly, the point was a metaphor for the blurring between real and fake. So, easily distinguished fake would ruin that.
If many MDs, via the IRB, say that this is a bad idea, but one MD says that it is a good idea and that MD then decides to go overseas to conduct the research, what do you think was actually going on? This is crazy stuff they are doing and many MDs think they should not be doing it at all. The incentives to skew the data they generate are super high and super suspect now.
I thought I remembered that the Public Health Service intentionally infected people in order to see what would happen, but Wikipedia seems to say that they intentionally withheld treatment from people who were already infected and deceived them about this, rather than causing the infections themselves (although some of the study subjects spread the disease to other people during the course of the study, which were new infections that could have been prevented by treatment).
Is Kensington really getting that bad? I haven't been down there in a little while, but my girlfriend still seemed to think it was going well there. She rarely goes herself, though.

That said I rent long-term (nearing a 1/2 years) in Liberty Village (Ha! I cannot afford to buy in this city) and my building seems to be half Airbnb units. I run into more people with luggage coming and going than I see actual residents. The faces are always changing except for the smallest set...
> The source of the recording is usually the best master known for that record (special remastered editions, etc.).

Usually what is happening here is you're getting a master that hasn't been compressed to death (see loudness wars). Vinyl is a shit source for 'quality', but most records aren't compressed to death so they can still sound better on a good set of speakers due to the dynamic range.

>>What options do you think were inadequately explored to sign the consent forms?

None.

Now, if you asked a question without assuming what you think I was saying, I'd tell you that Alexander's other options were to not use the IRB that he went to, and to explore the private marketplace of IRB organizations that provide much better service than the nightmare he dealt with - a very common practice in all fields.
Your kids will do many things that you don't want.

And in any case, not wanting your kids to do X is a horrible reason for delegitimizing the use of X by everyone.

I think that was a thread in I, Robot.

My favorite is how the robots on the space colony don't believe the humans could have created them, due to how sophisticated they are.
Yes, GPUs (or cloud) are the way to go at the moment if you have any training and want it quick.

HOWEVER, If you are careful, for some models you can get cost benefits by training on cloud CPUs. See http://minimaxir.com/2017/07/cpu-or-gpu/
It provides several different flavors of the C++ STL, including libc++. `libc++` is specifically the implementation shipped by LLVM/Clang (which is also what Apple uses).

The next release of the NDK (r16; due out sometime this quarter) will stabilize libc++ for use by NDK applications and it'll be made the default STL in r17 (which will be out by the end of the year).
I believe the link changed, it was a WSJ article first with no mention of the rape case. I doubted that they'd be investigated for small sums of payments.
Yes, Erlichman is known to have lied to support his political goals. The quote in question supports that claim.

A quick wiki search finds numerous clinical marijuana and LSD trials conducted in the 50's and 60's suggesting therapeutic applications. The CSA of 1970 classifies these drugs, counter to the then growing body of evidence, as having no known medicinal use.

We know that later, the CIA bought Nicaraguan cocaine specifically to sell in American black inner cities.

We know the US peddles patently absurd, fear and lie based anti-drug propaganda to school children in the form of the DARE program.

We also know, well, everything we currently know about various psychoactive substances.

The consistent thread this weaves is a bit more convincing to me than, "this politician lied about some stuff. Maybe I can't believe anything he's said?"
I don't think it quite works to try to talk about governments as if they are individual, coherent entities.

There are government agencies whose business is to collect information. The people working for these agencies will do so _to the extent that they are allowed to_, because that is what they perceive their mission to be. Other people's job is to set limits, and they will set exactly the limits they think they have a mandate to set. They get their sense of that mandate from many possible sources, but in a republic one of the most important sources is public opinion.

Which is where you get to the real kernel of the issue: In the USA, surveys indicate that most Americans remain in favor of large scale state surveillance.
The analogy with images is demonstrated in this screenshot [1], which is referenced in a StackOverflow answer on the topic of image scaling in web browsers [2].

When the high resolution image is downscaled poorly, some high (spatial) frequencies are aliased down into lower (spatial) frequencies, manifesting as blocky/jagged lines. The images are 2D data in the spatial domain, while the audio is 1D data in the temporal domain, but the aliasing of high frequency signal to lower frequency artifact is similar.

Viewing a high resolution image on a panel that has enough pixels to display it without scaling is analogous to listening to 192 kHz audio on a fantastic speaker system that can reproduce those high frequencies accurately, instead of causing distortion by aliasing them to lower frequencies. On the other side, viewing a high resolution image which has been downscaled poorly is analogous to listening to that 192 kHz audio on a realistic speaker system that cannot reproduce high frequencies, which results in those signals aliasing down into the audible range.

And as you say, there is a point where, for the viewer/listener's sake, it doesn't make sense to push for higher frequencies because even if you can build a panel/speaker that will faithfully reproduce those frequencies without aliasing, the eye/ear will not be able to perceive the additional detail.

I suspect that it is easy to fixate on fantasies of massive technological leaps forward, because the truly revolutionary changes that underpin our lives are like air: so common that we overlook them all the time.

If you were to sit down with a person from, say, 1750, and wanted to explain the modern world, you would probably tell them about things like antibiotics, cars and planes, snapchat, that sort of thing.

All the big stuff that we think defines the modern era.

What would probably really impress the hell out of them would be a supermarket, though.

To a person from that time, the idea of being able to eat fresh peaches in the dead of winter would be just as magical as being able to instantly translate Russian into English, and yet it probably wouldn't occur to us to bring it up because fruit at the supermarket is just... obvious.

So as we look forward, the question is, what will be obvious to people ten or twenty years from now?

The 10 year US bonds haven't had such low rates and for such a long time at least since 1962 (as far back as the Yahoo Finance data goes). Inflation is low. Your belief in the valuation should be linked to how you feel about rates and inflation. If rates stay this low for a very extended period than the valuation might be on the low side. At any rate, these are unchartered territories in terms of investment returns and valuations.

EDIT: even going back to 1912 the 10 year rates are unusually low for an extended period. The closest historic period is during the 1940's valuations back then (P/E ratios) were lower (peaking around 1946).
Assuming the market keep on growing over time as it has done for a very long time, all time highs aren't something spectacular or unusual in the stock market, in fact it occurs almost on a daily basis.

As an analogy; if you go to a grocery store, all the items on the shelves are at an all time high price, but no one is expecting the price of milk to drop drastically just because it's at an all time high.

I'm not a developer but I do serve as an adjunct professor for some technical courses at a local college.

I had some students ask me the same thing this semester and so I tried to really dig in to the different offerings and these are the points I made to the class:

1) I believe you will learn the most from EdX IF the institution putting the course on is reputable (MITx, HavardX etc)

2) The credential I think carries the most weight is Udacity, because they have the most rigorous testing. It's not an honor code.

3) I'd put Udacity's weight on par with most online colleges in Canada or the US (Walden, Athabasca, etc).

4) This credential won't matter to other colleges, or to large workplaces (thousands of employees) who have HR departments who want to just "have a checkbox"

Lastly, it's important to be able to sell the value of the credential. I have a degree from an online college that I got part time. The college isn't all that reputable. But, I have that degree because I was working full-time and still wanted to validate my skills in a different field.

So I worked evenings and weekends to make that happen, and to many employers that shows commitment and work ethic.

I personally think the best path forward is to learn what you can, and create a good portfolio. Shop it around, if you can't get anywhere with that try a Udacity nanodegree (watch the videos for free first, then pay the monthly fee and speed through the tests).

Finally if that doesn't work get an EdX honor certificate from one of the big name schools like MIT, they don't have much weight, but it may give a hiring manager cause to take a second glance.

I didn't say otherwise, and that's not relevant to Alexander's claim that the many of the standards are excessive and not merited.
