the decision now lies with the developer, not with the user. therefore, a malicious camera app developer would have to convince the developers of all targeted apps to support their app instead of the default camera app, which pretty much doesn't work.

A package manager is NOT the same as a company controlled Marketplace, i can intergrate my own apps, build my own ports, use python-virtenv with pip, Rust with cargo and so on...and the best thing, FreeBSD has no controll over what i have on my computer...and that's good.

There's no way for government to protect your property rights without infringement on my negative rights to my liberty either.

This is particularly obvious in the case of private ownership of land. Without private property rights I would be free to walk across and otherwise make use of that land it is your property rights which take that freedom away from me. And this isn't a theoretical issue either: prior to the enclosure of land in the 15th-19th centuries (https://en.wikipedia.org/wiki/Enclosure), most land here in the UK was common land that anybody had a right to make use of to graze animals and make a living. The expansion of private property directly took away that right and deprived many of their livelihoods. Even today we still have the Right To Roam (https://en.wikipedia.org/wiki/Freedom_to_roam#United_Kingdom) and at least walk on private land which provides for significantly more freedom than is available in the US (there is close to zero danger of being shot just for walking somewhere in the UK).

For other property it's less obvious, but enforcing your property rights still requires encroaching on my liberty. For example, without property rights, I would be free to walk into a shop and take whatever I wanted to. Or rock up to your unlocked car and drive off with it. The only way that this is prevented is through active enforcement by the state. Ultimately, if I persist in doing these things then I will be physically imprisoned. And it takes significant resources to run the policing and justice systems, just like healthcare. Now obviously nobody thinks I should just be able to walk up and take your care. But other forms of private property are controversial. In particular the idea that you ought to be able to keep all of that wealth that people give you (without taxation). You are only able to hold onto that wealth in the first place because the state enforces your right to keep it. There is nothing a priori that says that the state (which ultimately represents its citizens) must always enforce that right.

To summarise, many "negative rights", including the right to private property, have exactly the same ethical problems as "positive rights". At which point it becomes a simple matter of what you consider moral and important. You're right that state-provided healthcare deprives you of wealth that you could otherwise have. But the reverse is also true. You having the wealth deprives others of healthcare that they could otherwise have. You just happen to think that property rights are more "natural" and important.

> testing the system through millions/billions of miles driven?

Makes sense doesn't it?

Well, actually no. The Google cars drive the same route every day in Mountain View with no deviation, so those millions of miles are really the same 10 miles over and over. Even seen 3 in a row behind each other.

Making this a fine example of systemic exclusion
Yep. When I was in China in January, a person from the neighborhood committee called us and asked us whether we've been in contact with anyone from Wuhan, or whether we have any symptoms. Very simple, but contributes to tracing. In contrast, when I went back to the Netherlands 2 weeks later, nobody asked me anything. Even after I called the public health service, they told me I couldn't even voluntarily get tested even if I wanted to. Two months later, COVID-19 cases in the Netherlands surged sky-high.
I think bigger issues would be time related queries when dataset gets bigger as opposed to write speeds.

Has my present distance to a fire extinguisher been implicated in a spate of house fires which have killed or injured other people?

I as an individual can take the risks I choose to take with my life. I have no right to apply that to others though.

In fact the building I'm currently in was built to local standards which mandated all sorts of things in relation to providing adequate control of known risks related to the spread of fire, and has smoke detectors fitted for that purpose. Because the builder of the house might have been okay accepting that risk for themselves, but we don't let them just pass it on to others.
Yup. 500 errors are "the server is broken" (aka the server fails to fulfil the request), 400 errors are "the client did something it should not", including every case of "the client did something the server took issue with for whatever reason".

In fact RFC 6585 added "429 Too Many Requests" specifically for rate-limiting scenarios.

413 (payload too large), 414 (URI too long) or 431 (header fields too large) are likewise things which may technically be valid according to the HTTP spec in general, but which the server rejects.
The linked site does not contain all the statuses from the original registry, for example 425 Too Early is missing.

Understanding Swift’s OptionSet
The reality is that technical solutions can always fail. In medicine there is emphasis on giving human actors a kill switch (no, luckily not for the patient, phew...).

Of course humans can make errors too but are still superior to do sanity checks. From what I understand about this issue, pilots were not able to overrule the system that had wrong sensory information.

But to defend certifiers in such cases, their primary role is to ensure engineers sit down and think about all possible risks. They cannot ensure that every risk is accounted for. That is beyond anyone's ability. The primary role is to ensure this process isn't skipped completely and is executed with due diligence.

Of course a pilot can have a heart attack while the copilot is more interested in the stewardess at that point, but a kill switch doesn't have to be a panic button, but there can be a conscious procedure to activate a state for handling exceptions.

I think with today's technology it is still important to have such a mechanism to give back control.
I don't understand how the US can force a Chinese company to sell itself, can someone explain?
Unity builds are a neat idea, but they just don't scale. One of my projects is about 3k loc (for the time being...)

Takes 1.6s to build right now, under clang. (Amazingly, it takes 68ms with tcc, but that's a separate issue.)

If I switch to a parallel build, that time halves to only 0.8s. You can't do unity builds in parallel, because there's only one translation unit. Most people will probably get much better than 2x performance from parallel builds; I only have 4 cores.

You also can't do incremental builds in unity. If I touch just my biggest file (so only that has to be rebuilt), my compile time halves. Touch the next-biggest file, and it halves again. As a project grows, time it takes to do a full rebuild gets bigger, but incremental builds take about the same amount of time. (They may take slightly longer, as your headers grow or as the linking stage takes more time.)

You may have slightly better compile times right now, but they won't last. Incremental, parallel builds still have problems (especially when you get to the scale of linux or chromium), but but there's a reason few people use unity builds.
> How realistic is it to have no joined letters? Do many people really write large scale texts letter by letter with space between each?

Most of the people I know do this. Myself, I have never ever written with joined letters except when required to in school.

I consider it a leftover from the era of fountain pens (which are terrible UX for me as a left-handed writing LTR languages).

Even my signature is based on separate letters (tho blurred together as sigs usually do).

To be fair, Portland is in completely chaos and disarray[1]. Innocent people are getting attacked, mugged, and almost killed by ANTIFA and BLM[2], without any police-intervention. (Because, as BLM has taught the incompetent Portland-mayor, the police are the bad guys.)

The only example I can think of is a wormhole created by quantum fluctuations in the early universe, stabilised by a negative energy cosmic string, then cosmic inflation expanded it to macroscopic size and flung the two ends far apart. But of course the various features of that aren't universally accepted and are not likely to occur, so eh.
While this is cool and funny, the standard claims not to prescribe for general consumption, but to offer a standardised way to brew tea for sensory comparison. Which is great, but the procedure is way too limited:

> 2 grams of tea (measured to ±2% accuracy) per 100 ml boiling water is placed into the pot.

This means 20 grams per liter. That's ridiculously strong tea. 4-8 grams per liter is much more reasonable.

> Freshly boiling water is poured into the pot to within 4–6 mm of the brim. Allow 20 seconds for water to cool.

This is after putting the tea in the pot. But for green tea, you should let the water cool (in the pot or the kettle) before adding it to the tea.

> Brewing time is six minutes.

Again, some teas are better with a different brewing time.
This is the same universe that gave rise to the Tide Pod challenge.

I'd recommend the book "The Smartest Guys in the Room", it goes into detail about the financial engineering. Yes it was decided in the end that it was fraudulent, but it took a while for that to become clear. Technically, much of what they did wasn't illegal and it wasn't even obvious at the time whether it was smart or stupid.

For me the most interesting part was the culture, and assumption that they couldn't fail. Because of this Ken Lay (CEO) continued to leverage himself personally against the Enron share price again and again. When told to diversify with other investments, rather than sell Enron shares and buy others, he instead took out loans against his Enron shares to buy others. He was in effect trying to "have his cake and eat it too". Ultimately once the Enron share price fell enough, it caused the whole house of cards to come crashing down as contract after contract, both for Lay and Enron, triggered pay-out conditions, and they all ended up bankrupt.

I hope this doesn't end badly for Musk, but he should probably be diversified enough to protect himself against Tesla's share price declining, and it will be interesting when SpaceX gets to an IPO, whether his personal leverage may affect whether he chooses to take it public or at what price.
A great point. There should a single standard and well-documented way to do things. The documentation should be official, the user should not be expected to trawl the blogosphere and piece together the knowledge they need. There should be plenty of complete examples.

Ideally the official Find... packages should not make use of deprecated CMake functionality, they should be actively maintained to follow the current best-practices, so that they can serve as examples of the right way to do it.

As I rambled about in my longer comment yesterday, this kind of work shouldn't require you to think, it should just be an exercise in applying boring, samey, dependable boilerplate.
I think the forced part is because either they sell or stop being available in the US market due to the ban the US threatened with.

So they're not 'forced' to per se - but if they don't sell they'll lose a large part of their market. Or am I wrong?

Perhaps a more direct Julia analogy would be the built-in AbstractArray interface.

There is simply no question of how (to use their example) `mean(::CuArray; dims)` should work, it not only follows Base's notation, but extends the same `Statistics.mean` function, so that exotic arrays can be passed to packages written before the package defining them existed.

This is why managers need a high level of emotional intelligence, the ability to empathize and quickly place themselves in the position of others. Without those three qualities management is ill equipped to handle these kinds of things sensibly.

Sadly the above traits are more deemed leadership qualities rather than management qualities and so often missing in management.

Leadership skills are far harder to teach than management skills and also rarer in the population than the number it management roles there are to fill.

It looks to me like you see no difference between "I need to configure my environment" and "my environment is already configured by default". But, from my point of view, the difference is very important.

I like being able to type some J (or, most times, some K) in an email, in a note I take in my phone, in a comment of a C program, ... Yes, I could configure my environment(s) to do all this with a custom input method, but being able to do it with anything I find without any configuration is a huge advantage.
The equation is a bit similar to the one played out in the movie "Goodfellas".

You have two mobsters, the good mobster and the bad mobster, and a business. The bad mobster actively harasses the business in multiple ways, prompting the business to seek protection from the good mobster in exchange for buying into the business.

Of course, both the good mobster and the bad mobster are in the same mob, and benefit from the revenue stream from the newly acquired stake in business.
Founders should keep this in mind anytime they are negotiating contract terms with a corporation also. There is no such thing as a "standard" contract and almost all "mandatory" clauses are not actually mandatory. This also applies to real estate transactions and almost any other high stakes negotiating. Standard and mandatory are terms used to trick inexperienced or less powerful people/entities into agreeing to terms more favorable to an opponent.

None of this means you can necessarily axe all the requirements though. It entirely depends on your negotiating position. If a company wants to work with you badly enough they'll pay their lawyer the $500 hourly to modify the contract or approve your changes.

Sure, there are other factors. Taxes are like prices, states and countries are competing on them. If you can make up for high taxes, that's fine, but at some point it becomes a shitty deal, so people won't show up anymore. If you are rich, you can just retire in any country and preserve your wealth for yourself and your children.

A wealth tax of 2-3% would enormous. Combined with an average capital gains tax, the incentive to get the capital out of the US becomes huge. Yet, even 2-3% doesn't bring in that much money relative to deficit spending and stimulus bills, so who is to say it's going to stop there? If you're clueless enough to go with a 2-3% wealth tax, you're clueless enough to go with 5% and more (Warren).
