I understand the point you're making - that we must not be afraid to talk about genetic differences between people.

While I respect the perspective, there's a couple critical "implementation issues":

1. I've never heard of a case like you used in your example, of everyone from an island having sleep apnea which leads to lower IQ. The obstacles are that we've never seen a universal population wide disease like that (before you bring up sickle cell or something hold on), we've never seen such a disease consistently lead to "employable" side effects (say, intelligence or charisma or something), and we've just never had such a homogeneous population anyway.

2. The CPAP issue is open to literally anyone, and so what's the point in trying to figure out whether a given population is genetically predisposed to sleep apnea? Just continue to treat at an individual level (by providing universal access to healthcare)

It boils down to: separating populations to find cause of "issue" doesn't actually generate any useful information but does create fantastic weapons for racists. Instead, just persuing socially liberal policies such as universal education and healthcare do a great job of evening the scales for us.
Feelings and impressions are more important than you think. Stock markets for example are not perfect but instead also reflect human perception: https://www.investopedia.com/terms/r/reflexivity.asp

This deal requires investment at the start but will pay off in the end by lower costs caused by climate change. So what is holding people back? Their perception. They feel like they will die before the impacts will happen. They feel like nobody is doing anything about it so why should they be the first? Humans are built in a way that joining an existing movement is easy but starting one is hard. Germany helped getting the start of the s-curve going.
To see Google track you in real time, disable Play Services
In an attempt to de-Google my life, I recently disabled Play Services. Now, my Pixel 2 XL complains every time it can't "phone home."

Google wants to contact Play Services (itself a rootkit) every time you receive a call. You'll see the notification/complaint several seconds before the phone rings.

While driving with Maps, Google attempts to track you each time you enter a destination or cancel one as well as at regular intervals during your drive.

Play Services also tries to track me at random times for no reason when I'm not using the phone.

It tries to track you while listening to voicemail and the notification/complaint stops the voicemail playback every few seconds when it can't.

But perhaps the worst offense is that it tracks you as you scroll through your contacts. God help if you look up a phone number because, every few seconds as you scroll through your contact list, Play Services attempts to report it to Google.

I find this behavior reprehensible and I'm sorely looking forward to getting a Puri.sm or /e/ device.

Just for fun, try it for yourself by disabling the Play Services app and see how often Google is spying on you.
There's a number of factors related to that, I think. I'm engaging in informed speculation here, based on my experiences with my fellow citizens.

I think the short answer is that the US is physically huge. Just the state I live in alone is about the same land area as Germany, and there are 49 others -- many of which are larger than mine.

Just getting to an airport that you can take an international flight to the UK from can be a big deal all by itself. It's not cheap (an oddity about plane fares in the US is that domestic travel can cost as much or more than flying across the Atlantic), and can take a day or two. The cost of the flight from, say, New York to London is not necessarily the major portion of the travel expense.

The travel time is significant, as I mentioned. For a lot of people (pretty much anyone who doesn't live in the general north-eastern portion of the US), a "weekend trip" would require 4-6 days. Vacation time is limited, so not everyone is willing to spend a significant portion of it on an airplane or in airports.

Cost is a big deal -- traveling overseas is expensive, and the prices for things in the UK are quite high as well (probably on par with New York, but New York is very expensive). Most people who aren't wealthy (which is the vast majority of people) could really only expect to afford it once or twice in a lifetime, unless they are willing to sacrifice a lot of other things to make it happen more frequently -- and some people do, but most people have other priorities for the money.

That doesn't really pass the sniff test... distance to GEO is 36,000 km, the sun is approx. 0.5 degrees in angular size, that would mean a mirror with a diameter of 314 km in GEO. We do not have the technology for that.

This Banksy quote feels apropos:

> People are taking the piss out of you everyday. They butt into your life, take a cheap shot at you and then disappear. They leer at you from tall buildings and make you feel small. They make flippant comments from buses that imply you're not sexy enough and that all the fun is happening somewhere else. They are on TV making your girlfriend feel inadequate. They have access to the most sophisticated technology the world has ever seen and they bully you with it. They are The Advertisers and they are laughing at you. You, however, are forbidden to touch them. Trademarks, intellectual property rights and copyright law mean advertisers can say what they like wherever they like with total impunity. Fuck that. Any advert in a public space that gives you no choice whether you see it or not is yours. It's yours to take, re-arrange and re-use. You can do whatever you like with it. Asking for permission is like asking to keep a rock someone just threw at your head. You owe the companies nothing. Less than nothing, you especially don't owe them any courtesy. They owe you. They have re-arranged the world to put themselves in front of you. They never asked for your permission, don't even start asking for theirs.

I don't think it's a matter of pressure or choice, my grandparents simply lived in a more social environment.

Broad family trees, churches, guilds/unions, even free-range childhoods - gone or fading across the nation.

Aside from work communities, the rest was mostly innate. You can't "choose" to live in a bigger family... but that environment, those pillars of socialization, were what fed into the smaller social niches.

Or to take it even further: taking a walk in a park, stopping by to say hello, meeting to chat. I'd say some of the most important components of friendship aren't even "things to do."

>Good luck in the NBA if you’re 5’1” tall.

Sure, you're not wrong, but you've just stated an individual trait, not a population one. Try now to make the argument that someone is more "likely" to be pro NBA if they're of some arbitrarily chosen genetic background. You will run into the fact that 1. You will be totally unable to create rigid constraints for your genetic background, and 2. Statistical variance will be so high that you won't actually be generating useful information anyway (i.e. an effective predictor).

So yea, maybe one couple of tall people could have a tall kid and of course the kid has a better chance at the NBA than a short kid (sort of maybe. He could end up a footsie god, it's happened before and we have no way of predicting when it will happen next), but they might have had a short kid despite their genetic factors so the point is moot.

>My guess is that software development also has genetic mental requirements but there’s no definitive answer for that

You may guess all you want but I carefully avoid any feelings that are not fact based and don't generate any useful planning or information for me so I disagree with this point. There's simply no evidence of this and I don't see how this information could be significant enough to have an effect on any decisions I make in life (for example, hiring decisions).
I would agree with you if thousands of videos and accounts weren't removed daily due to false "intellectual property" claims and automated reporting. YouTube's system is terrible because they're so large that they've had to try to automate a system that can't really be automated. A decentralized system would require those claims to actually be validated before they're processed because, otherwise, it would be a waste of time and money for the companies making the false claims.

I agree with you on the Library of Congress. We need a digital LoC.

disclosure: memsql person...

the past few years at memsql we have watched quietly as competitors have released numerous benchmarks. often one particular benchmark that coincidentally fits into a niche strength. often cleverly ignoring its weaknesses. often against an antiquated version of our software.

we are quite proud to be the only database company to produce such a varied array of impressive benchmark results. no niche benchmarks. no old versions. as close to the truth as it gets.

other databases in the mirror may be further behind than they appear

Well, if you have some thoughts on it, I am curious what the other approach would look like. What are your thoughts?

I'm thinking they would have all the labor of taking it out, and all the labor of putting it in, but then much additional labor and repair time incurred by doing the component level repair instead of just grabbing another radio off the shelf. Recycling would be possible on the unit later and it could be installed as a refurb unit in another vehicle.
(MemSQL CTO here)

1. MemSQL is running with synchronous replication in all these benchmarks. All data is stored on a 2nd machine before any transaction is acknowledged as committed. You’re right this is not as strong as running with both synchronous writes to disk and over the network. MemSQL supports this as well and results in about a 40 to 50% performance hit depending on the disk speed. Very few of our customers run in this configuration so we didn’t include it (the edge case of multiple machines losing power is not worth the performance hit for them).

2. Can you point me to what you’re describing in the TPC-C specification? I have never heard of what you’re claiming. TPC-C has maximum allowed latency requirements for the 5 transaction types it runs and also requirements around the mix of those transactions in the workload. The goal of the benchmark is still to run as many "New Order" transaction per minute while maintaining the latency requirements of the other unmeasured transactions running in the background (this is what tpmC stands for). We used the Percona TPC-C driver for MySQL to handle this (with a few small bug fixes).

3. The main thing we wanted to show is that our performance on TPC-DS is similar (better at some scale factors, slower on others) to data warehouses that specialize in running these types of queries. We likely should have provided more details (per query break downs and what not).

4. We used the Percona MySQL TPC-C driver with some changes to make the initial data loading faster. That driver uses the “FOR UPDATE” clause in MySQL instead of running in serializable isolation level.

I know you did a lot of work on CockroachDB. The point of the blog post was not to attack cockroach (I personally didn’t want to mention it at all), but to show how MemSQL is different. We are one of the few distributed SQL databases with competitive results on all 3 major TPC benchmarks.
Yes, that is one anecdotal data point on a 2013 Model S. The 2012/2013 Model S drivetrain was notorious. Tesla warranted them for 8 years, and replaced them when they started to make noise. Here's an article with real statistical analysis saying 2/3rd were replaced by 60,000 miles. [1] This is back when Model S was basically a prototype.

Time will tell with the Model 3 how reliable it is. A major selling point is the reduced complexity of an EV. The Tesla drivetrain and battery is now widely considered the world's best and most reliable. Tesla has claimed the Model 3 drivetrain can be re-used on the semi and that it's tested to 1,000,000 miles [2]. Take that with a grain of salt, but it's a world different from a 2013 Model S.

It's CASE (Computer Aided Software Engineering) all over again! This idea rears its (ugly) head every few years. It isn't a help to programmers.

The reason we use text for programming isn't "because punch cards," though as a former IBM mainframe programmer I appreciate the analogy. It's because text is an incredibly efficient way of communicating even the most complex information.

A side note here: One of the reasons for Korea's rise to power as an "Asian Tiger" is that, many moons ago, one of their emperors decided to break away from the Chinese system of pictographs and replace it with a phonetic alphabet, allowing anyone to spell and pronounce words. The result was one of the highest degrees of literacy among nations anywhere. Alphabets are good for communicating with people and with processors, too.
Just glad no one was hurt.
> Abstract thinking, in the capacity of quick intuitive guessing, does not an abstract model make. You're conflating terms.

Reasoning in abstract terms requires the capacity to model what you are reasoning about in abstract terms. As far as I'm concerned, that's not conflation. As soon as the world appears to you in terms of higher level concepts, you have a model of it in your head that's abstract; not concrete. You seem to disagree, on the basis that an abstract model necessarily entails using glyphs?

A prediction, e.g. "the bike will tip over if it stops moving" requires that I understand on some level the concept of causality, the concept of a bike, the concept of movement etc. Using my understanding of these concepts, I can predict potential outcomes for my actions. You call it intuitive guessing, and maybe you never needed training wheels, but this is something that most people have to learn and internalize.

In my view, the notion, while riding, that it'll hurt more if you fall off at a high speed is similar in nature to "F = m₁m₂/r²", differing mostly in scope, terminology and subject. Newton's law of universal gravitation is a lot like an "intuitive guess" in that it's a prediction based on limited information that broke down with the introduction of new information.

> Running around interacting with the environment requires no more abstraction than an animal is capable of.

I agree. When did you last see another animal ride a bicycle, though? Even animals that are much quicker to react than us and have mastered within months of their lives movement and spatial awareness to a degree which most humans can only ever hope to ever achieve suck at simple mechanical obstacles. We're amazed when cats, that can jump several body lengths from one thin branch to another to catch a bird before it has thought to fly off, do something as conceptually simple as opening a door using a handle to get where they want to go. A dog that can smell and track down a hare in a field of flowers will amuse us to no end if it shows the slightest hint of recognizing some concept more advanced than a ball.
