That's a 25% increase! Yeah that's bad! He was already warned for using twitter to spread misleading info about the value of his company. He should know better.
There's still a reasonable PPC Mac/Amiga hobbyist community, many of whom will tell you about how much purer PowerPC is compared to the evil ugly x86. As someone who does PPC Linux kernel work the pragmatic part of me would like to drop support for a lot of these older machines, but as long as the machines are still actively used the support gets maintained.
It is not the ML model that is updated with information, but the predictive modeler herself is updated. She now finds parameters that make the model perform well on that specific test set. This gives you overly optimistic estimates of generalization performance (thus unsound science, and, in business, it is better to report too low performance, than too high, because a policy build on a model that is overfit like this can ruin a company or a life). For smarter approaches to this problem, see the research on reusable holdout sets.
You just call it something like T. If you want any numbers you need a coordinate basis.

At some point you’ll run into construction cost limits for multistory dwellings. I don’t know how close Berlin is to that point but given how much cheaper their rent is than other major cities they’re probably doing a better job than most of building housing.
Agreed, I would have loved to see it more like a detour along the correct spelling. Almost like a character based diff.

One weekday morning I decided to take my wife and daughters (I was working from home, and we homeschool) out for breakfast at a new breakfast joint. The sun had just risen, they weather was perfect and they had a patio. We were seated outside and blasted by classic rock, really great songs actually, but not loud and at 8am. I asked the waitress what the deal was, she said it wasn't them, the property management company had them installed (it was in a strip with 4 other businesses). What benefit would it be to the property management company? I'll never know.

> I've long wondered if Europeans and their descendants have evolved a more intense affinity toward meat

European diets changed drastically after their discovery of the new world and the introduction of grains such as potatoes and corn from the new world to Europe. Due to the introduction of these new starches, Europeans were able to diversify away from wheat and also cultivate food exclusively for animal consumption - something that led eventually to an increase in meat consumption.

That's the big thing that jumps out at me. There are very, very few serious economic policies that have this level of agreement among economists.

Greg Mankiw did a list a while back about what economists agree on:

Teaching kids to be paranoid of everything isn't good either. If your child is too innocent they won't know the difference when someone ask them to do something that is wrong. Far before they're the age of 18 they need to be able to fend for themselves unless if you plan to keep your child under your wing forever.

The "active amygdala = no empathy" point does not jibe with my lay understanding of the physical phenomenon of empathy.

That's the only one that I don't believe models our physiology in a useful way. The rest match up with some of the stuff I've read/watched.

Watch some videos by Robert Sapolsky on YouTube. He's a neurostuff prof at Stanford. Good presentations.

There's "Why Zebras Don't Get Ulcers" https://www.youtube.com/watch?v=D9H9qTdserM

Also an actual academic lecture on the Limbic System which contextualizes & clarifies some of the other assertions in the OP blog post. https://www.youtube.com/watch?v=CAOnSbDSaOw

There are more but hopefully YouTube's algorithm helps you out there. The Stanford lecture series is very interesting though Sapolsky doesn't deliver all the lectures.

edit: The only plausible, good faith explanation of the amygdala-empathy claim I can think of is that there are facial recognition studies designed to activate the amygdala https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4979579/ that showed some correlation between anxiety levels and ACC-amygdala connectivity. The ACC, or anterior cingulate cortex, is held to be responsible for empathy. So it may be an interpretation of that knowledge the author is talking about. I know that facial recognition tests are used for evaluation of empathy, sexual attraction and so on. This is probably the kernel of accuracy in the claim.

Or there may be other science on the topic that reaches a conclusion closer to what the author said.

The linked study is extremely interesting read.

This blows my mind (like everyone else's here)!

While playing digital copies of somewhat older movies (before BluRay rips came into vogue), a problem which surfaces frequently is that the frame rates of the video and the subtitle track are slightly mismatched, say video at 24fps, subtitle at 25.6fps(?). This makes the subtitles drift away from the video and require a manual intervention every few minutes. If I can't hear the audio properly for some reason, then I just become fed up and don't watch the movie at all. Add to that the existence of different 'cuts' for films, which add another dimension to the subtitle problem.

How would one even go about solving this problem?
Yep, deleting cookies via dev tools brings back the quiz.
This sounds like someone doesn't understand how Windows calculates folder sizes. It will never show the size unless you look at the folder properties; and even then, there's no indication when it's done calculating. It might be obvious sometimes because the number is continuously changing, but if it hits a lot of very small files, it won't visibly change for a while.

Edit: Actually, apparently there is a bug related to this in recent versions of Windows, but it's still a behavior that can happen even without a bug.

This is probably a wacky idea, but...

What if there is a quiz before the start of every article (optional, of course) that the reader can take? Lets say I am interested in child mortality rates, but I don't have any knowledge about it. I probably have wrong ideas too, about the topic. I take a 60 second quiz, then read the article - this will show how misinformed (probably) I am, and then inform me of the topic.

You sound like a smart guy and it'd take me pages to properly respond to everything. I try to avoid online political debates because I haven't found much ROI in investing in them. But I'm sure Sowell would be highly critical of the mainstream economic policies of both parties in recent eras. He's far more preferential towards earlier US economics.

I will say that there's a big myth that the US has been on some big market-oriented supply-side binge since the 1980s which is a giant myth in itself. The size of western governments, everywhere, has exploded since the 1970s... even if the tax rate hasn't.

Sowell would be just as critical of any policy directly benefiting the wealthy as well. He sees the far bigger problem as the countless "well-intentioned policies" intended (or at least sold) to help the poor/middle class that back fire, do nothing, or more often creates highly inefficient systems where only the politically connected get social benefits.

I highly recommend his book "Wealth, poverty, and politics" [1]. It'd do a 100x better job than me at explaining his general worldview, which is closest to mine. And it's hardly just lower taxes for upper/middle and keep the rest of the political machine the same (which is probably worst of both worlds IMO).

How to Book the Cheapest Flight Possible to Anywhere
Agriculture spread throughout Europe during the Neolithic, like the rest of the Mediterranean basin (and possibly towards India), and brought along massive deforestation and demographic growth. Those were deeply agriculture-centric societies far before the Indo-Europeans came around, not even mentioning Romans.

And in what parallel universe agriculture was centralized in Asia in 4000 BC ?

The big advantage of Asia was double or even triple crops.
Does that change whether it counts as "information"?

Nope, Gregorian Calendar and Solar calendar don't have exactly same days (although it is very small), and thus the different leap years.

> Why do governments go this direction when it causes so many problems?

I think it's fair to say in a democracy most politicians are motivated by money or votes. There are plenty of people who probably see this as working in their favor.

Next usually comes the affordable housing bond because you're right, the private sector won't see it as a good investment.

Writing a Rust Roguelike for the Desktop and the Web
The problem is that we are already doing 1 regardless of rent control.

Here there was a proposal to do a couple hundred units of entry level apartments and people shit their pants about it. It was about a quarter mile from the already poorest part of the county and people actually went to the planning commission and said stuff about not wanting the poors around there. One landlord basically argued he didn't want the competition.

In the end the state subsidies fell through anyway.

> In the general case, the hardware requires it; that's how computers work.

In rust, it creates the trait object right as it's calling a function that requires one. But "creates" is too strong a word -- it's just sending the virtual function table pointer along with the structure pointer and any other arguments, probably in registers. Only if you are actually storing the trait object somewhere does it matter much.

In your example, you have to construct the "derived" type each time you come from C to C++. Using an extra type is annoying. I think a better C++ example would be trying to do something closer to what rust does and use the C struct pointer most places, and construct the C++ object right before you need it. Would work, but doesn't come out quite as clean as it does in rust.

In any case, the main point is that the normal mode of C++ is to add vtable pointers to the structures to achieve dynamic dispatch, and adding stuff to the beginning of a struct does not interoperate with C code very well. The normal mode of rust is to not touch the struct layout and achieve these features through other means. I'm sure there's a way to work against the grain in C++ and make it work, but if you ask me, rust gets it a little cleaner in this particular case. Or you could argue that working against the grain is the normal mode of C++ ;-).

I've been thinking of designing my own smart devices, but they will need to fall back to simpler devices. For example, I want to build a smart lock that unlocks with a GPG key on my phone, but still has a key (bolt on motor to existing lock).

I just don't understand these smart devices. At best they're marginally more convenient, but they come with a lot of risks. I'm worried about software not getting updated, data in the cloud being compromised, or simple loss of function from not degrading gracefully.

My smart TV is nice because it has Netflix built in, but nothing else on the market is interesting to me.

Each tweet is a short public shout that is an attack of something else and no way to discuss substance or solve anything.

HN doesn't use any variant of Markdown, it doesn't use Markdown at all.

The only formatting options here are:

1. Surround text with asterisks (not underscores) to italicize it.

2. Indent text by two spaces (not four spaces) for code formatting - but please never use this for block quotes as people often do by mistake or out of frustration over the lack of formatting options - it ruins readability on mobile.

Why follow reporters instead of subjects they report on, collaboratively edited by many people?
Wow, weird. I wasn't being sarcastic. It was interesting to learn about it from someone who lives there. I guess that deserves a downvote.
There's a good reason most of the most-expensive places are on tight costal areas like SF and Manhattan, where outward expansion is possible without making any positive internal changes. Just constantly pushing out from the middle via gentrification instead of any realistic market development to match demand.

Not to mention NIMBY-heavy political systems which are common in urban areas... they are always extremely hostile to new development. Which of course benefits current residents in the short term but is a disaster for everyone in the long run.
Sounds like the meeting was actually quite effective in rallying the maps team behind a single solution ;)
Very cool! I find it fascinating to see what experiments other companies run, and especially what the winners were.

Wow. What a different website compared to most styles.
Construction cost limits are almost always not caused because of the cost of building the actual building.

The costs instead come from the extra rules and regulations placed on builders, by people who really do not want more houses to be built.
Public traded companies work like this:

You must tell the truth about how much money you make and spend, and report it annually to everyone, so they can make informed decisions about whether to buy or sell it the same as anyone else.

As long as you do, then you are allowed to sell stock. If you don't then you are not allowed to sell stock. The reasoning is obvious. It's too easy to commit fraud if you don't follow these rules. Therefore, you must agree to the rules to trade publicly. The SEC's job is to protect the public from fraud.

Spiel has created a mobile-first platform specifically so today’s fast-paced professionals can easily share their knowledge “on-the-go.” Educators, professionals, and thought leaders that are time limited can give video replies to questions directed to them in particular, or to a category in general. Video answers referred to as a "Spiel" get publicly stored, making it available for all users to view; subsequently decreasing the number of repetitive questions, while benefiting the community. Unlike written replies that are impersonal and detached, video answers are authentic, entertaining, and interactive. http://bit.ly/spielapp

Rent control is nativism just like prop 13. Provides special economic benefits unavailable to newcomers.
I think this also has to be considered in the context of an ongoing cataclysmic war encompassing the world where whole cities were being destroyed and of course they were developing a weapon to destroy them faster. Today, WWII is that long ago thing that lasted for a few years and then it was over. Soon the veterans and the Holocaust survivors will all be dead. To anyone then, a lot of things probably didn't seem as important. A lot of people reacted to the atomic bomb once it was public as the impending end of the world, too. So the scientists who knew about it first probably had their attitudes affected.
That's what I love about Spanish. There is this iron-clad rule that everything is spelt exactly as it's pronounced. Compared to English (or French), it's so ridiculously easy that (I sometimes think to myself) it must be a toy, not an actual human language.

And when they borrow words from other (not phonetic) languages, they just say "to hell with that spelling", and spell it in a perfectly logical way themselves.

It's funny how the conversation have changed now to Climate Change instead of global warming.

A lot of this has been pushed by the environmental organizations who despite their claims that CO2 is the biggest threat to humankind still are overwhelmingly against nuclear energy despite it being both safer, more scaleable, more reliable and actually able to provide energy compared to unrealiables like wind and sun.

If anything this just shows how long this discussion have been going on and how much of this is politics and ideology rather than science.

Is Your Conversion Rate Optimised Enough
Sure, sometimes VC align with your interests. But I'm just trying to make the point that taking their advice without thinking about it is ... inadvisable.

I've seen super terrible things happen to people. Sometimes you have to jump up and down and make a lot of noise that "notes on how to start a startup by YC" should be taken with much salt.

Anyway :allies:
In Québec we've had province-wide rent control since at least the early 70's. Landlords are allowed to raise rent annually up to a certain percentage determined by inflation (last year, up to 2.5%). Rent raises can also be appealed to the housing board if they seem unfair, or if the landlord has not been keeping up with maintenance. Prices can go up if significant renovations occur (which they almost never do), but even then costs must be split across all units in the building. In 10 years, across 9 apartments, I have not once had a landlord bother to raise my rent.

It's not a perfect system, but still today in Montréal you can get a $400USD 1 bedroom apartment in a good part of town, thanks to this system. It ensures that the working class can live near their occupation, and they don't have to commute from a slum neighbourhood outside the city. In many quartiers, you have the very poor and the very wealthy living side by side.

I believe absolutely rent-control (in tandem with a few other policies) has enabled Montréal to situate itself as a hotbed of creativity. We have one of the most dynamic and diverse art scenes in all of North America, and with a population on the island of Montréal still less than 2 million.

I definitely support this kind of legislation.
