I am fully aware of those videos and claims. Did you read my posts or the links? What I posted goes vastly beyond what Chris Montgomery wrote, and far beyond his claims.

Again, in different words:

Nyquist assumes infinitely precise samples. It's math, not computer sampling. This never happens, since samples are quantized. Having samples at the proper number of Hz is useless unless enough precision is there, and non-infinite precision implies the original signal is never reconstructable. We're dealing with computers, not the real numbers.

Take a pure sine wave. Sample it mathematically. Quantize those values. Now what sin value reproduces those quantized values? None. Never. They are rational numbers - it is mathematically impossible to fit a single sine wave to them, since sine is a transcendental function. End of story.

Sine is a transcendental function, so rational inputs (other than 0 in the case of sin) do not (except for input 0 for sin) give rational output. So you cannot sample it to perfection with a digital device. You can approximate it. That approximation matters. Digital sampling takes rational input deltas (sampling rate) and necessarily obtains imperfect samples, since you quantized the actual value of a sine wave. So Nyquist fails.

Yes, for a bandlimited signal of a given frequency, Nyquist lets you reconstruct that frequency given infinite precision. This NEVER happens in practice, since it assumes infinitely precise samples. Montgomery ignores this (and a host of other issues - he's at level 2 of a 100 level tower. People at level 0 see his videos and assume there are only 2 levels to the tower). Bitdepth matters. Nyquist does nothing about amplitude quantization, which is needed. It ignores the path to reconstruction - Nyquist only applies to a perfect (not floating point or integer) reconstruction of the signal. Nyquist does not deal with the fact that the quantized values, when pushed to any physical device used to reconstruct audio, is more like stairsteps than pure sine waves.

Most physical devices performing playback are more stairstep than smooth sine values, so they are not reconstructing the input signal - another issue that matters. Input signals are (nearly, up to quantum level) infinitely precise in amplitudes - output devices tend to be more quantized.

Please read the thread I wrote and think through it. I posted a link to a good discussion, I posted a simple experiment or two you can do, I posted (here) a simple mathematical exercise showing that Nyquist fails for this.
Why or how people deem "phantom braking" to be even remotely acceptable is completely beyond me. You are putting your life in the hands of a multi-ton steel box with a mind of (seemingly) its own and it "phantom braking" at highway speeds does not alarm you? In a normal world all of those cars would be immediately recalled.
I guess I am missing the reference to machines in the comment and all I see being satirized is an interview process.

Hey

I tried Felt and it looked good. However for me the marker / polygon moved significantly with different zoom levels which is a fairly big issue. This was in 54,-1 area (lat/lng) - I don't know if it could be as simple as different coordinate systems on markers vs mapping?
Plus codes are pretty much like GPS coordinates, but made by Google: https://maps.google.com/pluscodes/

For some reason Google Maps throws plus codes at you, but requires you to dig deeper to find GPS coordinates.

How much are you willing to pay for a legally dubious benchmark?
With random hard braking the question is not if but when and how often.

I'd say the question is whether we should tolerate cars with what you could call undefined behaviour. Imho we shouldn't.
In this circumstance (crashing into the back of a tesla breaking hard) you would have been the person primarily to blame. Yes tesla sells a dodgy "autopilot" that does unexpected things (and in my opinion should not be road legal until fixed), but you were tailgating to the point where you couldn’t stop in time. The car behind has to be responsible for maintaining safe separation to the car in front (under reasonable circumstances).

edit: The "you" in the above being the hypothetical driver.
Whoa, I really liked this. Even though it was super hard, and once I had a vague idea of the subject, I was entering relevant words from a list I looked up (before I knew that guessing the subject ended the game - I'm bad at reading directions.) But yeah I had fun and lost like an hour to that.

The first 6 US Presidents were decent, incorruptible men. Also, Abraham Lincoln is notable for his suffering, winning the Civil War and freeing the slaves. And, regardless of politics, anyone can see Jimmy Carter is a saint. He could be the first and last US President to be beatified and canonized... but let's hope it will be awhile before that occurs.

This makes nix seem a lot less intimidating than many other recent posts. I'll have to give it a try.
If people prefer gas that much then existing homes will be more highly valued. That does not change the equation for everyone that's already priced out of existing properties.

Considering the extreme shortage of housing inventory in our most prosperous cities I doubt gas hookups kill any projects.
> The other reason is that it is better! You can actually get an induction stove to heat up faster than a gas stove, if it is wired properly

They're more expensive, though, and it's harder to find ones without 100% terrible touch controls (especially if you're also trying not to pay a ton of money).

If you have a cheap gas range and want an electric replacement at roughly the same price, your options are all garbage, not high-quality induction ranges.

[EDIT] Oh, they also seem to be more fragile and harder and/or more expensive to repair if they do break, making lifetime ownership cost even worse than what the up-front cost alone implies, and that's already not great.
Thanks for your comment. Stocks got hammered but SaaS businesses continue to grow. Zoom is growing 50% YoY, Datadog 80% YoY...
>For example, suppose you have a pure sine wave, sample it with enough density to make it mathematically reproducible, then play back those quantized samples on a piezo making square waves - it sounds pretty good (and can be indistinguishable to most ears), but it is not the same waveform.

I'm pro analog, but the above is a common misconception, usually caused by the bad "popular science" articles on digital reproduction and sampling, which show quantization as little pixelated waveforms etc.

The waveform produced from a sampled digital signal recreates the original perfectly (for the target frequency), you can verify that on an oscilloscope.
I've built Flixi dashboard while back (https://appcatalog.webosarchive.com/showMuseumDetails.php?ap...). My last TouchPad died some time ago, and then I couldn't get the SDK going on a new workstation but a few users were running that thing still even not that long ago!
Non interactive zero knowledge allows one proof to be checked by many verifiers. I think folks would still consider that to be a zero knowledge proof no?

That said, yeah this hashing example is not zero knowledge because, among other things, the hash is not hiding.
It's often not. Many high- performance libraries use fine- grained locking within logical units (eg locking buckets within a hash table in the fast path rather than locking the table), which almost necessitates sharing references.
I think the target word vocabulary needs to be limited to exclude super abstract generic words. Today's seems to be within a few points of anything, we, and yours.

I don't think it squares with the VC industry - but the VC industry is just one way of moving money from those that have money but cannot build new wealth, to those that have talent but no money.

The initial move from talent to profitable business is what we need - not because we can see a runway to 18 months IPO but because what the duck else do you do with money other than create new better wealth for the world.

Previously this has been solved by government taxing rich and giving it to innovators through schools, universities and arms spending (simplifying slightly).

But apparently tax is bad now, and governments don't know how to pick winners to VCs are going to take over. If this is not a great idea we should try some other options - the OP has an idea. It's not bad. Others exist (including that tax one which apparently no one with money likes)
That was mortifying. Thanks for the correction.
Except these things don't have to rely on them. It's absolutely possible to build a portal-style website, spanning multiple different-level domains, without third-party cookies.

It really is unfortunate that the most popular browser is made by the same company that controls the most popular search engine, the most popular video sharing service, the most popular email provider, and the most popular cloud storage/collaboration service. This should not be legal.
I don't think that this is relevant at all in the context of this discussion - electric cooking methods - particularly induction - are superior to gas in essentially every way, shape or form - barring the production of wok hei, which is why the article stresses that so much, while conveniently leaving out all the massive downsides of gas stoves.

Gas stoves are also generally used by gas companies to get gas lines drawn into buildings, so that they can easily sell gas to the bigger consumer of gas - heating. And indeed, in this aspect too, gas is _vastly_ inferior to modern heating technologies such as heat pumps.

There is no real convenience trade-off when it comes to gas. It's time for it to die, permanently.
Okay, guess we disagree about what "context" means.

You can't write adam, you have to write Adam. This is because the letters don't carry enough information; you need to know the context that names are capitalized, which is information that is extrinsic to the text itself.

Similarly, you can't render a unified Han glyph without knowing the context of which language the text is in. This information is again extrinsic to the text itself - it is metadata about the text.

In comparison, when you can't write Hindi ru as r and u as you usually would but instead you have to write the letter ru as its own glyph, there is no extrinsic information needed. The letters are right there, so all the information for knowing how to render the letters is right there. There is no context needed.

But yes, if you define context to include surrounding letters, then yes you need "context" to render Hindi letters. But since the original context of this was the difficulty of supporting this context for programming identifiers, I'd say that this kind of "adjacent codepoints context" would not be something special to worry about anyway, because text renderers today already have to deal with this kind of "adjacent codepoints context" for emojis, etc.
Yes, you're right. But I wanted to warn him that this fish might not be worth catching.

> They are most likely talking about radar signature physics. Stealth to lower frequency radar requires physically implausible materials.

But then the question moves to: what are the weaknesses of those lower frequency radars, and can those be exploited to restore the advantage of the stealth features? The admittedly not-great Wikipedia page about low frequency radar seems to indicate it has a lot of disadvantages like being difficult to transport, prone to noise, and not being precise enough for targeting.
It works the other way around, this kind of trick is (stage) magic so if you're doing it, hey presto, you're a magician.
Interesting, is this built on any open source note taking/research tool, or just derived similar features?

I see what you're saying, and there's definitely reason to question which entities have gained the most influence from social media (out of corporations, governments, or activists).

As for "the purpose" of social media, I suppose a simple reductive answer would be "to make money", but there were (and I think still are) people who are idealistic about social media giving a voice to the voiceless, even if you think that, in practice, commercial messages and misinformation end up having a bigger and more negative effect.

A thought experiment I think is useful is to imagine how Western political discourse could have been shaped (by politicians and the traditional media) if grassroots movements couldn't form and raise awareness through things like "hashtag activism".[0] The fact that authoritarian countries invest resources in censoring or banning social media also seems to confirm that they see it as a threat rather than a harmless distraction.

Art Benjamin at Harvey Mudd College is another magician/mathematician. The two skills line up pretty well, it seems. When I got my math teaching credential there were two people in my cohort who did magic tricks as well as at least one teacher at the school where I did my student teaching.
This is genuinely how a significant portion (maybe 20% or more?) thinks, including my brother. The last time a school shooting happened, he harped on that teachers should be armed. He harped on this point to our mother. Our mother is a teacher of about 25 years experience, and makes $40k a year.

Next he will expect her to do the school's cooking duties too, in addition to being an untrained police officer and daycare and child support services and personal tutor and and and...
Interesting experiment! Here's a suggestion for a new protocol: set up a stand at some busy places (stadiums, train stations,...) and ask random passers-by to toss a coin a few times 'for science'. Should be easier to get to statistically meaningful orders of magnitude (if not, go to a cosplay event in 'The Witcher' costumes, that should help ;)), and arguably far more representative for the situations that we care about: the two participants will have become far more experienced at coin tossing after 20k tosses, but we care more about random people who hardly ever toss coins (we already know that people who practice a lot can control the outcome of a toss with reasonable accuracy).
I'd much rather the second largest city in the US take an initial stand that hopefully leads others to follow than sit around for 20 years waiting for Congress to fix things.

Interestingly enough, dinner hours are the times when California relies the most on natural gas for electricity production. Hopefully that changes in the future, but I wonder if all this ordinance does is further centralize natural gas usage at a single point of failure.

> Every example of corporate CO2 emission is in service of consumer needs.

They have no power over how such things are produced. Markets are not democracies. Everything those corporations are doing can be done in a sustainable way, but they choose not to for the sake of growth.

You're also forgetting all the manipulative advertising and propaganda driving people to consume more for the sake of growth.

Anyway, even if every single consumer made the absolute best choice (which is impossible given information asymmetry and finite wealth), then corporations would still be responsible for 90% and the news would still be talking about individuals 99% of the time.
Cast iron isn't much more expensive and much easier to maintain long term. Articles like this are vastly over complicating it to feed into some sort of cast iron mythos.

Unlike t-fall you won't damage your cast iron with a fork or metal spatula, and you won't accidentally get it too hot and burn the coating. Short of letting it sit around in water and rust they're virtually indestructible in the kitchen.
My father came to me yesterday saying he was harassed by Google: he's made the big mistake of installing google photos, but it was full capacity, google was asking him for payment, and he was not receiving his gmail emails because of it. He's over 70 so not so much used with tech, but it wasn't easy at all for me to stop google photos or to delete all photos. They make it as hard as possible, to milk people who don't know any better, such a shame. Anti-consumer scammers. People working for this company should feel ashamed, honestly.

In a sense, but the "ill-formed, no diagnostic required" hack allows for scenarios where what you wrote is nonsense, and a human can explain why, but your C++ compiler doesn't have that insight, so it compiles anyway and does... something. This avoids needing to teach the machine how to determine if what you did was sound.

But this is of course not a very safe way to write software.

I have a few that stick in my memory, but I don't know that they'd be appropriate - although they might give you a little insight.

1) We had a dev on the team who was adamant that we prefix all testing library functions in tests with their namespace. I argued that it in my experience it was pointless - no team I'd been on in the past ever had an issue with not prefixing them. He wouldn't budge on his stance. When he was on leave I changed all tests in the project, removing the namespace prefix. When he came back he seemed not too bothered by it, he got used to it and never brought it up again. We're still in contact now.

2) I was once brought in as a partner in a startup. They'd failed to make a product and I came in and built what they couldn't do from scratch into a working product in about 6 months. As more people used it the CEO started to become more active in the project. I was creating a new piece of functionality when he told me he wanted it another way. We didnt agree. I suggested taking it to users and getting their thoughts on it, he refused. We ended up disagreeing and then he pulled the "I am CEO card". Following the meeting I tried to understand why he wanted it the way he did and why I wanted it the way I did. I determined that my approach presented three separate bits of information in the graph, and his approach lost one of those pieces of information. I redesigned the UI to include all three parts of info but to look more like he wanted. I ended up essentially being pushed out of the business, he didn't give me any stock that was promised, and he ended up running that project into the ground. His company ended up failing and he's now a PM in some other company I believe...

3) I'm sure there are other instances but these are the two that pop into my mind. Most places I've worked people have discussions - perhaps there are disagreements, but they don't burn into my memory like the last two examples. Emotionally distressing events are much easier to remember.

Not sure how people would take those stories in an interview...
