My only gripe with delta chat is that the metadata most email stores keep per email message is measured in kilobytes (sometimes tens of them). View-source is very enlightening. For email messages which are often 1K-200K themselves with attachments, and somtimes > 10MB, I guess it's acceptable.

For one line "How about lunch today?" messages, it just hurts my engineer bones to use Delta-Chat on a regular email server.
Because a lot of the cost is opportunity cost, in monetary terms it will be higher for richer families.

For example, if the lower earning parent decides to stay home with the kids, that "costs" $15k/y if their take-home pay after tax is $15k, vs $100k/y if it's $100k.
Rare as it is—and I’d argue it’s not as rare as some people think, having experience three avionics GPS loss-of-signal events in the past two years (in different aircraft)—they’d be nuts not to have considered that risk in the design. I can’t find the AFM supplement for Safe Return but to a first approximation, it wouldn’t be out of the question for it to go into a heading and altitude hold until it reaquires.

I don't think this is the point. You are trying to solve a social problem via technical means, and that generally does not work.

Spam/scam email isn't a great parallel: that sort of thing is a more-or-less anonymous party intruding into someone else's life in order to try to sell them something or steal something from them. Blocking that kind of communication is the correct solution, and that's what success looks like.

Getting people to have nuanced, respectful conversations online is a completely different thing. If you get to the point where your best option is to block the other person, or moderate/delete their posts, that's a failure, not a success.
A constitution is the high level document that your citizens agree are the foundational principles governing the state. They are a set of general points that nearly everyone can understand at that level and agree to.

They are not the minutiae and laws that govern in detail.

104 is too many principles, or at the wrong level of detail, to be at the level of a constitution for people to discuss in concept and agree to as general participants in a society.
I'm going to post this even though there is a large chance that it's going to be poorly received:

This is simply an extension of what happened to urban poor (particularly blacks) in the latter half of the last century, and our failure to solve those issues adequately is simply allowing the dynamic to self-replicate.

It happened with drugs (crack cocaine vs opioids), it happened with housing (contract housing and gentrification vs subprime loans and asset inflation), on and on. See also Native Americans on reservations, essentially abandoned by the state for having the audacity to want some measure of self-determination. Whatever we allow to happen to the least of us, will eventually happen to most of us.

I come from the perspective of a military brat, a descendent of slaves, born overseas. My ancestral home is either unknown or a town built on the site of a plantation, depending on your perspective; my childhood home is an abstract idea shattered across 5 states and a dozen physical buildings; I have no memory of my place of birth and would have to get a visa to see it. I have a strong predilection towards dismissing sentiments concerning "home" because the society I live in has ruthlessly ground out any sentimentality I might have had towards it.

However, I also know what the break-up of community has done to black people in the US, the ignoble gift of desperation that the dissolution and rot of family and economic opportunity leaves to people. That's now playing out for American whites, and as we've seen, it carries with it a very serious and threatening sense of aggrievement, rooted in the kind of entitlement minorities could never claim without putting their lives on the line against their fellow countrymen. Therefore, even in my own grievance, I see the necessity of compassion and action.

I don't think a modern Homestead Act is necessarily the answer, though, because it doesn't get to the crux of the issue, which is our willingness as a country to let despair fester in one pocket or another, as long as it's not too close to home. I don't know what fixing that is going to take. Giving people money to move might be a part of it, but I don't think it's the be-all-end-all. There needs to be a more fundamental shift in how we view the right of people to secure shelter and build community, and perhaps of our responsibility to sacrifice and provide for this when it comes to people who aren't our own, may not live or look like us, may vote differently or work different jobs or have different dreams. We're all tied together.
Does your resale assessment also include withheld taxes?
What are you learning if I may ask? And building?
In theory I agree with the idea of charging for Co2 emissions, the problem always comes down to the execution, which in general means some kind of "carbon tax" system

The problem with the carbon tax systems I have seen most of them are setup in a way not to actually change climate or anything to do with climate change but instead set up to fund unrelated agenda's and often end up being counter productive to the actual goal of reducing carbon emissions / other population.
I should probably dig a little more into the microeconomics, but for me as a consumer the only difference between an autonomous car and an (human) Uber is price. If we assume that the price of the car stays the same, insurance and fuel still have to be paid and the cab app gets their cut - how much of my ride is really attributable to the cost of the human driver? So how much human labor can be automated away to the benefit of consumers? Not much I think.

Given current hardware prices, it seems like the car itself will be a lot more expensive; so how many trips need to be taken so that the variable cost advantage exceeds the increased fixed cost?

Driving is a ubiquitous human skill and tens of millions are looking for work, I believe it will be difficult to undercut them on price.

Drivers also often do more than merely drive - they help with the luggage, they clean the car, they can talk about their city.

Long-haul trucking is a different story, there is a massive labor shortage and letting big rigs go from one warehouse to another without the need of a driver looks like a huge opportunity.

Again recapitulating what a paradox is. If time travel works at all (the premise) then I can look up a historical event, and send a hand grenade back through time to that event. What then? The response "you obviously can't do that" isn't answering anything. What happens when I do? Deliberately, to defy the argument that it's impossible. What then? That's the whole issue.
Nahh, plenty of suburbs are set up with a nice quaint downtown area, with walkable housing surrounding that, and bikeable/driveable housing further out.

That very much depends on a case by case scenario.

I’ve seen WP used for everything from personal blogs, international news sites, shopping sites, and even fantasy sports games. The diversity of WP is definitely a strength. But it does mean that there’s not going to be a 1 size fits all alternative.
The burden of proof is on showing that the unicode view is, in your words, a more capable abstraction. My thesis is that it is not. This is not because it necessarily does anything worse (though it does). It must simply do something better. If there were actually anything at all it did better—well, I still wouldn't necessarily want it as a default but it would be a defensible abstraction.

The heart of the matter is that a Unicode codepoint sequence view of a string has no real use case.

There is no "universal principle" that we use abstractions always, regardless of whether they fit the problem; that's cargo-culting. An abstraction that does no work is, ceteris paribus, worse than not having it at all.
I found myself mildly nodding along to this waiting for the moment of clarity where he describes more fully the elite ladder but he doesn't and so I have no idea how to contrast this middle tier with the upper tier to see distinctions. What's an example of the Elite behaviors/language? How would I know Powertalk when I see it? What would an Elite do/have to show their true status?

I definitely accept that I'm not an elite. I am "wealthy" in a strictly relative financial sense but I have no political power/connections derived from it and have never tried to gain any. This has always been my personal distinction between say myself and the true elites. Wealth doesn't inherently get you power and I don't really even know how I would leverage what wealth I have to gain power despite this being a potentially viable avenue. Is this not a much better distinction?

> For libraries that are statically compiled or used as part of your own software it's a different story though.

That's still not "legally murky"; that's the GPL working as designed. If the component has enough value, that's an opportunity to sell an alternate license.

Of course, if your primary value proposition is something other than the library (such as a paid service that the library helps programs integrate with), by all means use a permissive license.
Synergy dates back to Silicon Graphics hardware.

An often overlooked feature of synergy is the ability to share clipboards between machines. You can copy a URL from your email and paste it into a browser on another box. Particularly useful if the reason you're doing synergy is to do cross-platform testing and validation.

The thing that made me stop using it was that they punted security to be someone else's problem, so you had to set up some ssh tunnel and be sure to run it only over that. It's not so bad on Linux or OS X, but that's quite a bit of extra work on Windows.

Does barrier take care of authentication or session encryption?
I personally think these things have a future, but everyone is just marketing them at the wrong people. They're marketing them wrong, if you look at ecommerce, it's clear there is lots of companies that want to buy instead of build. For the majority of generic companies, it's literally not possible. It's not even possible to build the majority of the tooling/framework/generic business logic. I think projects that target developers as their core market will fail. Developers, even at companies, just don't have the budget to buy these things at the costs it would require to make them sustainable. They don't even have the authority to make such a decision, again look at ecommerce and look who decides what software gets bought and built upon; it's generally not the CTO. It's the CEO and COO. But of course, you need to have a professional level of support to make it worthwhile for the company to buy it. The upselling on this is also reasonably good again as seen by ecommerce and other areas.

Oh and one other thing, I think any solution that isn't as vast as the ecommerce solutions are to ecommerce will also fail. Most of these are generally very small and don't tackle any issues companies will have after the MVP stage.

(Disclosure, I'm working on such an application/business framework.)
I think this is a bit of a stretch. The assertion I took issue with is that "Software architecture probably matters more than anything else".

Yes if you want to deconstruct the term to the point of absurdity, and say that whatever shape your program ends up in implies some "software architecture" then you can say architecture is always relevant, but I would consider it a stretch to say this means it's also the number-1 priority in software development.

If you read my comment, you would see that I'm arguing that software results, and software development as a process matter much more than thinking about architecture. I would also argue that every time the term "architecture" came up in a professional discussion over the past several years, this was a sign we were going down the wrong path.
Ok but why should we care about that in copying?

This is my mental model for what's going on:

There's a bunch of bytes stored on a CD-ROM in a defined order. Zeroes and ones. Copy them in order. You should now have a file on magnetic disk or flash that is precisely those byes in precisely that order. Anything that can make sense of one should be able to make sense of the other.

What am I missing here?
yes, making autonomous driving work in central Delhi or Agadir will be much different from a US highway.

Maybe it's too cyberpunk, but I can already see the headline of road pirates capturing autonomous cars and taking them apart for spares. Those sensors, the GPU and computing units are quite valuable.
Cars spend most of their time at rest, don't travel at cosmic speeds, and when they collide, don't send tens of thousands of pieces of shrapnel flying around the world for months/decades.
Most of Florida will be underwater by 2100 so preserving that forest doesn't sound all that to valuable to me
> People preferring detached houses is fine. Just take off the subsidies and let the market choose the mix between suburban houses and high density housing.

Exactly. If someone wishes to own a detached single-unit residence, fine. I'd prefer they didn't but that's not my decision to make for an individual.

The problem comes when people want to control what's built within a quarter or half or full mile of the residence they own. (And, no, before someone comes at me with this specious reasoning, there's a huge difference between "build a nuclear power plant next to a daycare" and "different types of housing near each other.")

As a matter of public policy, I will always advocate that we do the environmental and financially efficient thing of building closer-in and closer-together. (We gotta add in some standards for noise transmission, too.) But preserving a specific type of housing in a specific location in amber forever is not reasonable and should not be continued.
Correct. Frisco TX was mostly pasture 30 years ago and now has a half dozen 5A high schools. Thats 2000+ students. They dont build smaller schools because that’s optimal for football teams.

Lake Travis west of Austin is ~3000 students. Packed classes but got them 5 state championships.
I'd second this recommendation, given your price-bracket. My home laptop is a 2020 LG Gram 17 (which I've augmented to 40GB RAM and a 1TB Samsung Evo Plus SSD). The combination of sheer screen real-estate plus incredible lightness makes this a joy to work with. Obviously, it's never going to win in raw performance benchmark comparisons, but I tend to move any significant heavy lifting to cloud anyway.

What makes things easier for me is using it in conjunction with remote VSCode (into either local WSL2 or aforementioned cloud boxes).

Of course, if you're wedded to specific Mac software, then I'd imagine that an M1-based machine will be your only realistic option.

Wholeheartedly agree. Also, debugging logs for that same purpose can be great.

Often enough, that person might be yourself. I've been very grateful about my own comments in code areas that handled some obscure edge cases.

Not to mention multiple layers of abstract base classes. I'd say „write your code such that you'll only ever need one IDE jump out of the current scope (and back in) to figure out what's going on“
As you may already know, we have a HUGE fusion reactor ( fuses 500 million metric tons of hydrogen each second. [1] ) approximately 149.5 million km away, and it's ready and free* in that sense that we don't have to build it, maintain etc., it's there, it's working 24/7 and will be working for at least 5 billion years without any maintenance.

(you need surface to get it)

All we have to do is to harness the sun energy in the most efficiency and harmless way.

Almost all the energy used on earth comes from the sun. The nuclear*, geothermal and tidal power are more or less exceptions.

* (I'm not against nuclear power and research, as we need that technology to be able to travel in space in smaller spaceships rather than this large one (some may call it earth) we use now. Right now we travel where our sun goes, not where we like to explore.)

In every energy usage the key is the efficiency of the conversion.

Fossil fuel's efficiency is less then 1-2% from the sun due to the efficiency of the photosynthesis [2]. All of the fossil fuels are nothing but stored solar energy with less then 1-2% efficiency. And we don't calculate with waste from the mining refining transportation etc. energy cost.
And for useful energy (work) you have to burn it in a power plant or a car or whatever with maximum 10-50% efficiency [3]. So the overall efficiency is less than 1%.

On the other hand solar cells with 20%+ efficiency are commercial available, wind farms are better and hydro power can be even better. (wind and hydro power are also comes indirect from the sun)

(BTW the low efficiency of the photosynthesis is why the corn based fuels are waste of the solar energy, and land. You could generate the same amount of energy with solar power on less than 1/20th of the land with corn. If you need fossil fuel, algae is a much better alternative, as it's photosynthesis efficiency is higher than corn [4], also does not require valuable land, which can be used for other agriculture purpose (food) )

But, far the largest pro for the solar energy is that it will not run out in the near future (at least 5 billion years, even earth will be destroyed way before the sun run out of fuel), fossil fuels will run out, it does not matter if it's 50, 100 or 1000 years from now, but it will run out. Period. (that's the same problem with current nuclear power technology beside other factors)

So you have an energy that practically will not run out, have better total efficiency about 20-100+ times than fossil fuel (and side effect it's cleaner), * and someone still surprised that this is the future...

** yes, we need to work on energy storage

It isn't a fact, because you keep saying that. It's reasonable to ask what constitutes spyware, and categorize analytics either in or out of that category.

In any reasonable definition of spyware (it spies on you to the creator's benefit and not yours) then analytics goes in that category.

Baked into this theory is the belief that people only live in cities for job prospects, and not because they want to for every other part of their life. The belief is untrue at least for me and everyone I know.

I started it for two reasons. First there is close to no easy to read content when you begin learning Japanese and there is demand for such thing.

The second reason is to see how far I can go like this. It is a sort of thought experiment like you say in your comment.

Not to mention, even if you could manage to remember the symbols that way, it would still be next to useless, since you still couldn't SPEAK Japanese at all.

> But what does population decline look like on the ground? The experience of Japan, a country that has been showing this trend for more than a decade, might offer some insight. Already there are too few people to fill all its houses – one in every eight homes now lies empty. In Japan, they call such vacant buildings akiya – ghost homes.

> Most often to be found in rural areas, these houses quickly fall into disrepair, leaving them as eerie presences in the landscape, thus speeding the decline of the neighbourhood. Many akiya have been left empty after the death of their occupants; inherited by their city-living relatives, many go unclaimed and untended. With so many structures under unknown ownership, local authorities are also unable to tear them down.

It doesn't help that the Japanese have a strong bias against old/used homes, so land with a home on it is worth less than a vacant lot (because you have to factor in the cost of demolishing the existing home). I'm speculating, but that would probably also lead to houses that aren't built to last, and thus fall into disrepair more quickly.
