> 'Central Planning' inspired by Marx,

The Communist Manifesto starts with a chapter praising capitalism for bringing unheard of increases in productivity, growth. Even for trade serving as a "battering ram" that drives down xenophobia. Here's a quote praising capitalism:

> The bourgeoisie, during its rule of scarce one hundred years, has created more massive and more colossal productive forces than have all preceding generations together. Subjection of Nature’s forces to man, machinery, application of chemistry to industry and agriculture, steam-navigation, railways, electric telegraphs, clearing of whole continents for cultivation, canalisation of rivers, whole populations conjured out of the ground — what earlier century had even a presentiment that such productive forces slumbered in the lap of social labour?

He goes on to praise the advances brought by "free competition". Then he turns the tables and argues that the reason capitalism will eventually fail is that it is too efficient: That it will eventually bring crises of simultaneous over-production and under-employment; that it will automate away employment to the point that the proportion who can afford to buy their products will be unable to consume all that it can produce.

"Central Planning" has no basis in Marx.

Central planning is a largely Stalinist conception, developed out of ashes of "War communism" during the Russian Civil War. Lenin saw how it failed, hence New Economic Policy, which re-opened some markets and allowed for a softening of planning similar to what Deng later did in China. It was Stalin who undid most of those reforms again after Lenins death, and who went even further in making centralised planning a dogma, and it was based on his wilful misinterpretation of Lenins ideas, not on Marx.
From the demo video this looks really interesting for games/use cases that are centered around the >1000ft view.

Even in the video showing off the technology things look downright terrible up close. If you pause at the very beginning you can see handrails on the stairs that are just odd floating blobs, cars have all melted into the ground.

It is incredibly impressive that they have managed to get aerial LIDAR into a game engine, but the visuals are quite jarring up close.
I've been using PostGIS a bit for a toy project with Elite: Dangerous star system data. It's been a hoot, but I do worry that I'm going to start having trouble optimizing my queries. Finding all the systems within say 20 Ly of our sun can take upwards of a few seconds, and I've already added a GIST index on the positions.

I also find it a bit strange how 3D feels kinda tacked on, but it makes sense when you realize most maps are in fact 2D.

Anyway, my 2-cents of experience. If anyone has some good advise for > million row, 3D spacial optimizations for PostGIS, please let me know.

On HN, sure. The other 3.6 billion smartphone users out there? No. The top voted opinions on HN are niche and don't represent the general population in any way. You can see this effect on other threads. Here are a few classic examples.

- Everyone on HN hates Facebook, and yet 2 billion+ people use it every day.

- Privacy is a paramount concern on HN, more important than anything else, and yet billions of people don't care as long as their dick pics are safe (https://www.youtube.com/watch?v=NRWxk7o-QlI).

- HN users hate ads and would happily pay for the privilege of eliminating ads. In the real world? Youtube has 2 billion monthly active users, only 1% of whom pay to eliminate ads.

- The ideal HN smartphone is one that has software support for years, is rootable, can have it's OS changed on a whim, can install any app from any app store. Hardware should be modular, with a swappable battery, camera etc. So Fairphone, basically. Units sold - 200k in 5 years. iPhone, the exact opposite of this in every respect (except software support) - 1 Billion in 5 years.

What I've said is so obvious it's self evident. But now and then people do get surprised and maybe annoyed when they find the world doesn't reflect the gospel truth preached on HN. At the time of this writing, your comment is actually downvoted ... for implying that the general population might not be Tasker-Termux installing, life automating power users.
Uhm. Yeah, prototypes of the next general vessel have exploded while gathering data.

Room temperature does not mean safe for carbon life, I'm sure at a far enough distance from a nuclear reactor's core there's "room temperature".

But at that time, there must have been very few heavy elements so any life must have been "plasma life" and "room temperature" probably was very unpleasant for them.
The lane keeping assistant from an rental Audi (2019 model) tryed to crash me several times to a tunnel wall. Suddenly the car tryed to turn hard right into the wall. It was very scary.
Years ago I used to use the MS Launcher, however I noticed strange behaviour when in low 2g signal areas...Apps would take longer starting up. I'd tap on an icon, nothing would happen and the launcher would appear frozen, few seconds later the app would open.

I noticed the launcher was sending traffic whenever I started an app and it was affecting app start times when in low and slow signal areas.

I didn't dig in to it, but I suspected it was sending app usage analytics and the launcher was blocking until its usage data was transferred.

Another MS app "Your phone companion" is also sus. Preinstalled on my S10, it uses 20mb of data a month and I don't use it at all. Receives very frequent updates, its changelog is "Not provided by developer", and it has many permissions.
Making extremely aggressive predictions about a topic that you know nothing about isn't "thinking big". Somebody with massive media attention and countless acolytes needs to wield their power with care, especially given that a pandemic is driven by human behavior (if it's not a big deal, why wear a mask?). Not knowing what you don't know is just foolish.

I got a Model 3 on lease in 2019, and stumped up the extra for FSD. I switched jobs last year and had to return it. When I ordered another I didn't consider getting FSD for a moment. In the months that I had FSD, it rarely enabled navigate on autopilot. Even with this caution, it managed to do something that scared me almost every time it was enabled. e.g. pulling out in front of another car when overtaking, or taking a corner much too fast. Eventually it got to the point that I didn't dare enable it, and certainly not with anyone else in the car.
Meanwhile, advanced summon was basically useless, only working when I was almost next to the car, and then only driving at about 3 mph, and once again taking dangerous routes. Self-parking was fun, but nothing that plenty of other cars don't have too. Regular summon is useful for tight spots, but that's about it. I think that's the only thing I miss, and even that's mostly a party trick.

The actually usable stuff - namely autopilot - is available without FSD. All this said, the car is great, even though FSD is a con.
The infrastructure required for trains is many times more expensive than road, so ends up being impractical.

Trains can't pass each other, so you will need multiple lines with lots of trains, and they don't serve all transport needs unless you manage to get rail outside all shops for instance.
The ping is probably the uptime and connectivity monitor, which can be disabled. It regularly sends a ping to ping.ubnt.com.
As a startup, the market is often not mature yet and a lot of work needs to be put into growing the market. Two competitors in the same field often grow the market faster than two people doing two different things. Android and iOS are great competitors, but would the touchscreen market be as big without both of these? Or would people have stuck with Symbian and BlackBerry?

Just let your competitors grow, focus on improving your product. Let your competitors spend big money on marketing and branding. Then steal their users with a superior product.
You could likely more than 55 open source text editors too. I could name at least 15 offhand, I think.

I understood at least five years ago that the series is never going to be completed. Fans will be milked _a la_ Christopher Tolkien ("look, we found a few manuscripted pages that seems to be a draft for a chapter", $20 for 100 pages, hardcover and illustrated), but I won't spend another cent in any Martin book until "Dreams of Spring" is published. And it will never happen.

Also, Martin is 100% against fan fiction, and the main reason is $$$ (he barely conceals it). He would never allow anyone to work on the series unless a load of money is deposited in his bank account. Good for him if he gets it!

> if you mean Uber should pay their driver more and eat the loss

they don't really eat the loss - it merely spreads the cost onto all the drivers in that case, rather than specific drivers (e.g., the payment for all drivers would decrease by a small amount). May be it's going to be a very small amount, such that nobody cares. In that case, it makes business sense to do so - and sell the PR that uber is more disabled-friendly than their competition. A corporation cannot be altruistic.
Since Bitclout as a platform is really early we have decided to keep the initial bit of the experiment simple. Every quarter we will use 10% of the fund's proceeds (revenue in the form of rev share from companies, carry, etc) to buy Khoob coin. We have a few other ideas in mind once the Bitclout team decides to open up an API. Hope that helps!
I've noticed a trend of games graphics being fairly oldschool while the mechanics are modern. Maybe this'll lend it's self to that trend?
For something like URLs I'd use the hypothesis Python module and rely on their implementation of URLs (and if that changes the test will fail for newly formated URLs), for everything "custom" I would extract problematic test cases and include them as examples.

Testing doesn't take too long on my machine (maybe 10 seconds), but even if it would, it would be totally acceptable as I run it pre commit only.
Do you have a source for this?
I thought for the gdpr it was enough that data is not easily accessible. For example, it is not necessary to delete PII from backups unless they can be automatically restored (and are reasonably encrypted). Hashing PII thus falls under this category.

While the raw materials needed for silicon and silicon carbide are extremely abundant, the semiconductor industry needs many other elements that are much less abundant, e.g. gallium, germanium, arsenic, antimony or hafnium and also some that are extremely rare on Earth, e.g. indium, tellurium or gold.

The rare elements may be needed as dopants, when they are needed in very small quantities for each device, but those quantities add to non-negligible values for the entire huge production of semiconductor devices.

However, the rare elements can also be the main constituents for the so-called III-V and II-VI semiconductors.

The fact that the other better semiconductors require large quantities of rare elements has been a very important reason that has prevented the replacement of silicon in a large number of applications where it is an inferior solution.

For example, the GaN transistors and the white LEDs need not only gallium but also relatively large quantities of the much less abundant indium, which might limit some time in the future the expansion of their applications.
I want to see a further analysis. A huge jump like this will certainly leave a readable trail in the data. There is plenty we could learn from this.
>The concept of 'transaction' doesn't really make sense in this approach, since I'm directly modifying the data in memory, every change I make is atomic and can't fail, and I flush the data to the disk atomically as well.

So you don't have mutable data shared between threads then?
Well Samsung has the exact same setup. So why blame them when you give a pass to apple?
My LG G3 had it in like 2014 or whatever year I bought it.
And that difference is also what makes self driving on roads so much harder that on rails.
Just bought 2021 Model 3 SR+. Did not opt for the FSD package because the features it delivers were no worth $10k to me. The included Autopilot is more than sufficient for my foreseeable needs.

For me, “foreseeable” also includes FSD actually becoming a real software package we can download for a fee. I expect that package along with Tesla Network would be worth somewhere around $US30k/year for the first couple of years until no more taxis are driven by humans.

I also expect that either FSD/TN will become available as a subscription option where I can send my car to take part in Tesla Network while I am not using it, or I will be able to finance the purchase of a new FSD capable vehicle and the car will earn me enough money to cover the cost of ownership and participation in TN ie: it will cover the cost of commercial registration and insurance, tyres, maintenance, and payments on the principal + interest loan used to purchase the vehicle. I don’t expect it to be printing money for me, but I do expect a better ROI than having my money in a term deposit or superannuation (somewhat like 401(k)) account.

IMHO once any vehicle hits the commercial market with fully autonomous capability, the concept of private ownership of passenger vehicles will be dead within ten years.

I fully expect this Model 3 to be the last car I buy for my own use. I anticipate robot taxis being reality within a decade, even for limited scenarios such as inside specific geofences covering the “safe” roads inside a city’s metropolitan limits, and the well maintained highways linking those geofences regions.

In the meantime I am enjoying the comfort of a car designed for long distance travel with pleasant seats, quiet interior (quieter than my Jazz), and reasonably attractive styling.
Yes - even a splash of water won't concern people as much. If they had a way to secure from the screen not cracking, well that's something most people would appreciate.

They do but there is both a wire fee and a 1-2 day delay (and no weekends). I have literally decided “hey, let’s go to Vegas” and been on a plane within three hours, on a weekend. A wire just doesn’t work there.

Additionally, I also play locally and it’s tough to get access to tens of thousands in actual cash immediately, especially in a small cardroom or “home” game.
There's got to be limits to biological and technological evolution.

After all, it took ~billions of years for life to evolve on Earth and we're not immensely different than a monkey or dog.

Also, we have very few genes compared to all other animals, we're like a 7zip of genetic information, each gene coding multiple proteins, a spaghetti dna code that's very good at what it does, but surely it limits evolution.

If there is anything at all to evolve at, intelligence/emotional wise.

What would a human or alien species with an iq of 1000 be able to achieve vs what we can achieve in the exact same Universe?
I am writing an open-source line simplification algorithm[1] with PostGIS. So far it's a few hundred lines of SQL-like code[2], but it will grow.

I have never written anything serious in plpgsql, so this is my first non-trivial project. Writing in PostGIS is a strange mix of SQL (fully declarative) and a "real" programming language with variables, arrays, functions and loops. The mix is very interesting and requires getting used to. But doable.

Things I like so far:

- geometric functions are very robust and well documented. Reference manual[3] is amazing. Creating/editing/iterating over lines and polygons, detecting their features, is a breeze.

- good integration with QGIS -- I can see the result graphically on my desktop system very easily.

- I can even write tests[4].

Things I am worried about or don't like as much:

- The SQL/procedural mix requires a lot of getting used to, and sometimes "simple" things in a "real" programming language becomes complex here. E.g. I would love to have mutable linked-lists. Or moving data between "sql-world" (rows) to "plpgsql-world" (arrays and data structures) is non-obvious, and best references are, unfortunately, stackoverflow and scripts of others'.

- My program will run on a large data set (e.g. all rivers in a country or a continent). I will want to optimize it. There is an out-of-tree profiler[5], but "unofficial, out of tree" always adds risk.

- Biggest one: deep copies everywhere. Since plpgsql does not do any memory management, it is deep-copying everything. Sometimes (often in this algorithm!) I want to add a vertex to a line (=river bend); that always requires a full copy of the whole bend. When I know it will not be used and will be safe, I would like to say "I am mutating this geometry and I don't want a deep copy".

In general, I like it for algorithms. Though the moment it needs to hit performance-sensitive production, I believe I will re-do it in C (which, looking at the postgis source code, is quite write-able too).

And a cookiecutter for Django + Turbo, very cool. Thanks!
They are doing considerably worse than those in Hong Kong, Japan, South Korea.

If the US had stayed in South Vietnam, they'd likely be living at the same standard of living as South Koreans, instead, they continue to live in a fairly oppressive system without rule of law, basic freedom of expression, high levels of corruption etc.

Thailand would have likely benefited as well.

Thailand is often cited as a 'special case' due to it's lack of direct colonization relative to the rest of the area.
It's really nothing special. I wrote the whole thing in, like, a single afternoon. If you're interested, here it is:

It's not really a general purpose diffing algorithm. It probably doesn't handle every corner case as it only does what I need it to do in the few places I actually need it.
I agree about the HN bubble, but not every comment has to reflect the larger market; The comment is about the power users and it reflects the significant portion of HN.

Pre Covid, the only real expectation around mask use in "other cultures" was that people wear one in public while experiencing symptoms of illness like cough or fever. It's an entirely different thing from the post Covid state of affairs, where 100% mask use is absolutely the expectation in any kind of mixed public setting.
Not sure about the details, Forza Motorsport 4 has completely redeveloped the tire model at some point, with fresh intel from (IIRC) Pirelli, and they only improved since then.

That's not true. Mitch McConnell got rid of the SCOTUS 'filibuster' lowered it to 51 votes - pretty hypocritically based on his statements but you can't take McConnell's word you have to look at what has power.

Harry Reid previously lowered cloture threshold for non SCOTUS appointments, but only after Republicans act(ed) in bad faith and refused to "Advice and Consent."

They refused to confirm 2 very important seats for 'cost savings' and claimed that the DC circuit was 'underworked.' This is in the context of anti-Obama everything and no matter how milquetoast the nominee was.

I still think there might be something here. You can allow certain aggregations (like “sum of the tax column”), but they have to be explicitly permitted; otherwise shuffle and hash everything enough times to make a single lookup sort of cheap, while a scan very expensive (plus distribute over enough physical servers and make the network between them low bandwidth to thwart lower level attacks). With enough regulatory or legal pressure on companies to lock down their data, paying this premium might start to look attractive; one could even found a startup peddling the World’s Slowest Database™!

Edit: what I was thinking originally was that in the world of paper-only archives, these massive leaks were all but impossible, yet business could still be done. It should be possible to combine this slowness with the convenience of computers.
