That’s going a bit far. I’m in the games industry and have used opus regularly, it’s a great codec for games, often the hardware decoding is so restricted that we’re using software regardless so we might as well use something like opus.

The licensing restriction is unfortunate, but only restrictive for those with very specific goals, under normal conditions BSD is a wonderful license for game devs since you’re free to use the code and only have to add an acknowledgement somewhere.

I suppose a public domain game might hit the same limitation, though as a non-lawyer I would guess the chance of anyone with standing trying to sue anyone implementing from this spec is realistically zero (though I don’t fault stb for being unwilling to roll those dice!)

MRIs are fundamentally expensive. Yes we can bring the price down a bit, and we can set more money aside for them, but they’ll always be limited by their price.

Even if this technique is much worse (I can certainly believe it is) the price might allow uses that would never be practical with MRI even with the best financial support. For example, ultrasound might be viable for use in GPs or small medical facilities which could never dream of justifying an MRI machine.

You’re both imagining different scenarios.

Scenario 1: 20% of staff tested failed. Individual targeting is pointless because the issue is systemic. This has happened in aviation, it’s common for accident investigators to conclude that the entire company culture (or even the entire industry) has failed to handle a problem. They don’t waste time in cases like this pointing at individuals.

Scenario 2: you test very regularly and nobody fails the tests. Except Bob, he fails the tests. In this scenario, your threat analysis document will recommend retraining, firing, or restricting Bob specifically.

Scenario 2 almost never happens because nobody has data that good. If your sampling frequency or ability to conduct tests are limited, no specific sample is enough to cover the entire problem. If you focus on a punishing (or just re-educating) the 20% who failed then your next test will fail for (potentially) 20% of the 80% who weren’t retrained, and thus didn’t learn anything.

TLDR: you need to choose the approach based on the situation, but we collectively tend to treat security poorly enough that we’re almost never in the fortunate situation where scenario 2 fits.

Disagree, though you’re right it’s a little bit similar to the eu flag, but only a little, plenty of countries manage with more similar flags.

Flags don’t exist for the period where they’re gaining recognition. Compromising the significance of the iconography for the temporary gain of not being misidentified during the period it isn’t recognisable would just mean if it gains recognition it will forever be less than it could be.

In other words, with flags you need to play to win, not to survive. Better that the attempt have a higher risk of failure with a great flag than a lower risk with a mediocre flag.

The pale blue dot is an excellent way to represent a global outlook and “we’re all in it together”, not sure I can think of a better pedigree for this concept. I’d perhaps have been tempted to make it a smaller blue dot, but flags do need to be recognised at a distance, so it can’t be too much smaller.

This is true, but since you always need a bit of hope in all the bad news, worth noting that if you focus solely on electricity generation, the fossil fuels from generation decreased last year. That’s the first time it’s happened when demand increased as normal (ie if we disregard things like covid which decreased fossil fuel use by suppressing demand). Electricity use went up as normal, but renewables went up faster, cutting out the normal fossil fuel increases. Whilst this isn’t quite going to be a guaranteed every year thing yet, it’s going to happen more and more, and in a few years we can expect to see the last year where fossil fuel use for electricity goes up, followed by an inevitable decline.

Of course there’s a lot of other uses of fossil fuels than just electricity, so we’re still using more each year and probably will for a while yet, but it’s still a major milestone and a change in how the world works that can be celebrated, especially given so many things are switching towards electricity as a basis at the same time.

We are fixing the problem too slowly, but the ball is rolling faster and faster now, signs a promising that we will eventually fix it, now the question is how much damage will be done before we get there rather than whether we’ll get there.

They already tried pushing back against c-sections, turns out giving overly opinionated options to women that discourages things that are medically beneficial in a large portion of cases is not helpful and caused a lot of unnecessary suffering and some deaths, now that policy is thankfully long gone, though the opinionated attitude it generated in some continues on sadly. my wife had a particularly large first baby, natural birth might have worked, but would have been risky, rather than being given unbiased options, she was pressured towards induction over c-section since it was “more natural” (I suspect mostly because it would have looked better in the hospitals stats to keep the c-sections down). The early induction failed after days of suffering (as early inductions usually do, turns out), and then she had a c-section anyway (which having reviewed the options was her original preference, but was pressured out by the doctor), the c-section was vastly more successful, as you’d expect from the statistics (and a lot less suffering, which doesn’t show up in the stats but is obvious once you concider the process). Im willing to agree neither should be recommended in most cases, natural births are safer in most births, but the best thing anyone can do is give the facts as they apply to the person giving birth (and keep their opinions well out of it).

I fully admit that personal experience has biased me strongly in favour of c-sections, but only when the stats support them, which they often do.

That’s pretty flawed argument on the face of it, very few things win a cost benefit analysis if you disregard the benefit and thus require exactly zero cost.

The real question is whether detransitioning or other negative outcomes are greater than the number of suicides prevented by allowing early transitioning, and that’s a rather more complicated hurdle to jump.

Yes, and I think that’s actually intentional, they’re rewarding renewables way over the odds without needing to give politically controversial benefits. The rewards are just an inherent result of the existing system. This is why renewables are growing rapidly in the uk.

Of course we’ll need a way to resolve fluctuations both rapid and slower. Rapid fluctuations are handled by pumped hydro and increasingly by batteries.

The slow fluctuations (day/night all the way to summer/winter and good/bad weather patterns) are much trickier, I think it’s still unclear how well handle them, but it will certainly be partly handled by having an excess of renewables, though we’ll likely need some other solutions too, nuclear is probably one of them.

The implied part is “within common conditions” it’s a law limited to a specific regime, much like Newtonian physics. We know it’s not universally true but we can see it’s often true in common scenarios.

In the extreme case, as road coverage approaches 100%, the city stops containing buildings so the traffic will drop towards zero, so there’s actually a balance point somewhere, but roads are quite inefficient for high density cities, so probably the balance point would be less about fulfilling traffic demand and more about reducing the demand by demolishing most of the city.

I know the thread is about tvs, but since gaming has come up, worth noting that at computer viewing distances the differences between 1080p/1440p and 4k really are very visible (though in my case I have a 4k monitor for media and a 1440p monitor for gaming since there’s 0 chance I can run at 4k anyway)

The obvious use-case for unsafe is to implement alternative memory regimes that don’t exist in rust already, so you can write safe abstractions over them.

Rust doesn’t have the kind of high performance garbage collection you’d want for this, so starting with unsafe makes perfect sense to me. Hopefully they keep the unsafe layer small to minimise mistakes, but it seems reasonable to me.

You make a strong case for voice, but that doesn’t necessarily invalidate their argument, they never said voice should be replaced.

Here’s some ideas: 1. A data side channel 2. Use it to send originator for each message, have unique note on other end per sender so they don’t need to check visually, but also show on their display so corrupted or suspicious sender can be verified, in desperate circumstances (rather than the current case of “that cannot be done at all”). 3. Digital audio, allowing actual high quality audio, which we know does improve comprehension, which should not be optional in this context. 4. Take some lessons from modern coms systems on how to handle overlapping coms, plus the extra bandwidth from digital, so overlapping coms is handled gracefully (I realise the realtime nature prevents being too clever, but perhaps blocking all but the first to speak and playing a tone if you’re being blocked), perhaps with some sensible overrides like atc and anyone declaring an emergency getting priority. Currently overlap obliterates both messages and it’s possible for senders to not even know their message was lost. This has contributed to accidents, whilst basic direct radio transmissions cannot avoid this, smart algorithms with some networking could definitely reduce the failure cases to very rare and extreme scenarios 5. Let atc interact with flight planners on aircraft, show the aircraft’s actual locally programmed flight plan to atc, with clear icons if it differs from the filed plan atc has, and perhaps as an emergency only measure, allow atc to submit a flight plan to the aircraft (not replacing the active plan of course, just as a suggestion/support for struggling pilots, “since you have not understood my instructions 3 times, please review the submitted plan on your flight computer, note how it differs from what you programmed”) 6. Aircraft usually know where they are, and which atc they’re meant to be communicating with, have the data channels talk even when the audio channel is not set correctly. If incompetent pilots forget to switch channel, you can force an alarm instead of launching a fighter jet, or just have a button for “connect to correct atc” and a red light when you’re not on the correct one.

That’s just the ideas I’ve come up with just now. 4. Is probably quite hard to get right, and 5 could add load, so should be done carefully. But hard to believe the current system is technically optimal, or even vaguely close to optimal.

Admittedly, I know the real reason is that having 1 working system for everyone is better than a theoretically great system that is barely implemented and a complicated mess of handoffs between the 2. But with care they can absolutely improve things, but feels like things are moving a few decades slower than they should be.

The article explains the weaknesses of the password-centric approach:

> whether by phishing or exploiting the fact the passwords are weak or have been reused

1. Phishing is harder when you only ever enter your password into 1 place, and that one place is designed to be secure and consistent.

2. Much easier to have exactly 1 strong password than unique strong passwords for every website.

Is it better than a vault full of random passwords? Probably not, beyond pressuring the user into using the more secure method
