I've felt strongly for a few years that there is a market (strong interest, if not financial) for a small computer designed to let you be creative and expressive and to learn how computers really work. Over the past year and a half, I've built up a BASIC-like system on my own bare metal kernel on ARM64, giving a boot-to-BASIC programming and prototyping environment in a few seconds. I've worked down the stack as far as building an SBC-based custom hardware with HDMI and keyboard that also works as a handheld portable with onboard display & speaker. You can also do inline ARM64 assembly and memory peeking/disassembly as well as instruction-level step debugging. Polyphonic audio, direct I2C/SPI/GPIO/etc. access (i.e. at the byte level), and more.

It's just radically freeing to not have to wait for a boot, to have direct control over hardware resources like the frame buffer and audio registers, but to start with something as simple as Hello World and go in either direction from there — up in programming complexity or down in systems understanding. I'm very close to getting it into friends' (and their kids') hands. I'd love for it to take off, and have experience actually selling services and products, so I don't think it'll just be a hacker toy, but who knows? Regardless, it's been probably the single best learning project I've ever done. And it's so fun! It'll continue to be so for me whether it sells and/or has a community that builds up around it, or if it's just my passion.
Most cargo is going long distances that passengers should fly for. The needs of freight and passengers is different enough that they should almost never be on the same track.

When humans are on a train speed counts and they are willing to pay extra for it. When freight is on a train they can save money by going slower.
My home as a child had been a duck farm. My father converted it to an orange trees (and all kind of vegetables) orchard, it was 3k m2 (that's almost eight acres) so we had plenty of space.

It was hypnotic watching the sharecropper, with just a hoe, directing the water from the reservoir to all the trees, lettuces, watermellons... I wonder if those skills were transmited from generation to generation for centuries. With modern irrigation systems, I guess they're being lost.
Vacuum travel in a a tube does actually make sense. It may not be viable (yet?) but the idea is sound.

A big problem is a breach in your vacuum. Keeping the atmosphere out is expensive.

But what if where you’re building it has no atmosphere and is geologically stable or dead? Then a lot of problems go away. You don’t even need a tunnel necessarily.

Yet another reason why colonizing the Moon makes 1000x more sense than the romantic pipe dream of the red planet.

I'm not saying you're wrong about ZGC, but I will say everyone heard exactly that line also at the time of Android 1. And that was not a language "not designed for it." (And Android is still not using it.)
I’d much rather have a language specifically for creating apps than another generic language. It’s actually my opinion that Swift got worse since they started wanting it be used for more things like the server side.

Colonizing the moon makes sense because you can easily build hyperloop on it?
It's worth a try, thanks :)

The bank (Square) issue is that I ordered something online, FedEx screwed up the delivery, it got returned to merchant, but merchant does not respond. I asked bank for chargeback, but they can't do one as the package got delivered (back to the merchant). Their support script only allows chargebacks when there is no delivery at all. They tried to get me to persuade FedEx to change the package status to nondelivered, but I refused, so they gave me the money back anyway and closed my account because it was easier than changing their immutable support script to allow for an edge case where a package was delivered, but not delivered to customer.

For what it's worth, I find it remarkable what you actually can do with C with just a few libraries. For instance it's entirely possible to write a simple video game in pure C with a few well-chosen libraries for things like audio and asset loading.

There's just so much prior art out there.
It's a fine research project, but in terms of offering actual transportation services to people, there are a thousand more effective things to do to make high-speed rail services available, convenient, and economical.

High-speed rail is slower than a plane, sure, but it's way faster than a car.
You don't really need to remove air resistance to beat Amtrak though.

Coppola isn't a multi-billionaire. His net worth by most estimates is around $300-400m. Much of that was built on successfully suing Warner Bros. in the 1990s for $80m, which he used to build out his vineyard, food, and resort businesses.

SysV init has the ability to "respawn" a single PID, which I have used in the past (principally, replacing HP ServiceGuard clustering):

xy:3:respawn:/usr/bin/return_to_life

If the above process exits to much, the syslog will record "return to life respawning too quickly; disabled for 5 minutes."

This is all much more pleasant in systemd, which can understand and restart a whole group of processes, even when the parent process exits in the course of startup.

Money Laundering for Good is still money laundering. For all the good that people say it has, it is undeniable that it will enable evil when oppressive governments have new ways to project power untraceably.

Whether you love or hate the CIA, the CIA will project power this way, and probably already has. And there are a lot of people who hate the CIA.

But it wouldn't be that hard to expect to see black market arms deals be done over crypto. Or payment to terrorists (and their families) as well.
You're not wrong, but I wasn't speaking using this level of specificity.

They also don't look at things continuously for psychological reasons like being bored, sensory reasons like being distracted by something else, physical reasons like having their line of sight blocked, social reasons such as the event ending, or biological reasons like being asleep or deceased.

And neither would computers be looking at things continuously, if anything the discontinuity would be even more obvious as computers use "frames" of processing, as well as camera shutter speeds, instead of just being a function of the overall system's response time.
Most other parser generator systems give you indication that what you're writing is probably wrong, by stating e.g. that a grammar is ambiguous.

S := A '+' A | A '*' A

A := ...

If you do that in most PEG systems I've tried, you're just going to get the wrong result with no indication of what might have gone wrong, unless you know where to look.

> This is agression on the Ukraine

Someone steals a chunk of Ukraine territory. Six years later, someone else admits that it happened, and that's aggression? The aggression was taking it in the first place!

(Yes, the one who took it in the first place is the same one who "recognized" the taking six years later...)

The only way this is aggression is if Russia uses it (or Ukraine's or the west's response to it) as a pretext to take more territory.
You're going to call out someone for being uninformed,

Your opinion is purely speculation, and only true for people of your skillset.
Practically speaking, as long as they can convince people with control of capital (including the US gov't) that it's worth investigating.

The proper answer to your question requires information you're not going to get by asking HN, it's like asking how much time we should spend investigating fusion power. It completely depends on what leads people have, how promising the those leads look, how many "hard steps" are ahead of us, the benefit if we made it past them, etc.
I’m building a hosted data warehouse for different verticals. My goal is to target people interested in doing analysis, but acquiring data and setting up even datasette is too complex, especially if the data needs transformations to be easier to comprehend.

Then I’m building that into a platform where people can fork any query, modify, and publish with their own analysis in order to build a portfolio.

My first market is sports data. There are many aspiring analysts, and I want to 10x the number of people who do this work. And I think the best way to learn Analysis is SQL, and the best way to learn SQL is by building off other peoples queries (learn by example / exploration).
I don't think you're necessarily wrong, but how does putting a train in a vacuum tube solve the problems we currently have with passenger rail?
Developing domain-specific languages/minilanguages is claimed by many to be idiomatic for many Lisps.

And DSL is an especially strength of Racket (especially with the syntax objects, pattern-based syntax transformers, module system and submodules, and `#lang`).

But, just to avoid giving non-Racketeers the wrong impression... I don't recall anyone ever calling a piece of Racket code non-idiomatic merely because it didn't introduce a DSL or syntax extension.

In my (abandoned) Racket book, I intended to get people commercial-grade productive the first day, and introducing syntax extension wouldn't come until calendar weeks/months later. (Related: there'd be an entire chapter at the end, entitled "Don't Use `eval`", starting out like: https://lists.racket-lang.org/users/archive/2014-July/063597... :)
Meta-analysis is an application of idea #4 (Bayesian Multilevel Models) in the article.

What makes meta-analysis special within a multilevel framework is that you know the level 1 variance. This creates a special case of a generalized multilevel model where you leverage your knowledge of L1 mean and variance (from each individual study's results) to estimate the possible mean and variance of the population effect.

The population mean and variance is usually presented in funnel plots where you can see the expected distribution of effect sizes/point estimates given a sample size/standard error.

Researchers have also started to plot actual point estimates from published papers in this plot, showing that most of the published results are "inside the funnel", a result that is usually cited as evidence of publication bias. In other words, the missing studies end up in researchers' file drawers instead of being published somewhere.
Okay, but crypto already existed when all this transpired. If crypto is such a good idea and would prevent these problems, why didn't they just use it?

> The freezing via the EMA would thaw after the EMA expires in a few days.

The PM is on the record admitting he is considering extending the Emergency Measures Act, potentially for months.

His Minister of Finance has already declared she now plans to make some of the financial controls permanent.

Whether or not you believe these measures to be appropriate, it is incorrect to claim they will expire in the next few days.

Because airplanes are slow. In a vacuum (or in space!) you can go a lot faster without using a lot of energy. NYC to London in 2 hours including stops (Note that this assumes you cross from Alaska to Russia if you can cross the Atlantic instead it would be faster).

The expense is what kills it. The other problems are solvable with money, but there is no way getting around all the material needed to build it.

> The capitalist's answer is that regulating companies to prevent them from steering to the most profitable items is both impossible to be adequately done and prohibitively costly.

True, but only because that’s the wrong approach. The correct regulations are the ones that result in more competition. That’s treating the cause rather than the symptom.

If Amazon had to seriously worry about competitors, they wouldn’t be focused on selling overpriced garbage. Why? Because customers will notice that Amazon sells overpriced garbage, and will instead buy from somewhere else.

I don’t know what those regulations might look like, but I do know that pretty much every single “evil” behavior in the market can be solved by throwing in competition. It’s not always possible (e.g. maybe someone is locked in to a single vendor due to a bad contract), but when customers are given choices, the choice that offers the best value will survive in the long run.

Sure, some of it is implementation-defined, but in practice you need to write ultra-portable code anyway in order for your compiler not to pull the rug out underneath you.
