How far are you from getting deplatformed from TC39?
Pseudo-relevant anecdote: I wanted to buy a used car a few months ago off someone on Facebook. We were meeting up same day so the easiest method seemed to be cash. I went to the bank to withdraw $7000 and was informed, much to my surprise, that it is impossible to withdraw more than $3000 without 48 hours notice.

Suffice it to say, I've been seriously considering the tradeoffs of hoarding cash under my mattress.
wow why?
The ‘beauty’ of hyper expensive fuel is most will happily do that over the alternative - going bankrupt and/or freezing to death.

And those cabins were always a minority over folks in the cities. Being able to afford to hire someone to bring wood or coal is different from just going outside and chopping down whatever looks ready. (Though really you need to season it, and that takes time)

It certainly isn’t everyone that is so poor that it is a concern, but Dickens used the theme for a reason.
I mean isn't that the reason preppers love gold/silver bullion?
It's a common misconception that other people think alike oneself, and that everybody think rationally. As always, it depends.
Agree. Even if we could theoretically use it to our benefit, any such technology will disproportionally benefit these monopolists. They are the intended users, it's meant to secure "their" data against us hostile users. Its purpose is to literally provide a safe haven in our machines where these companies can do whatever they want without fear of our intervention. Unacceptable.
Do not use Webpack for small personal projects. Zero-config tools like Parcel are much better for that.
My best guess would be to contact someone from the study group directly via email and ask about obtaining an engineering sample for a potential commercial product (no really, they'll probably appreciate it).
At this point the wood is likely still being produced in situ (i.e. a few guys making it in a phys/chem lab).
The more interest is shown to them, the more likely they are to start looking at contracting the process out, thus making material easier to obtain and lower cost.

From what I've read, I'd expect it to behave similarly (in yield/toughness/hardness) to cast aluminum but with a tendency to split along the grain still, for machining purposes. So fairly hard, but not super ductile. The density will be in the same ballpark as magnesium if my math is right.

But... 'ecologically conscious' won't mean anything until production can be scaled up. When you're measuring things in raw carbon-footprint, it won't be able to break even with recycled pop cans merely due to the low-quantity batches they're processing now.
It could be viable in mass production based on a previous article I read in Nature. The process seems simple enough that I could replicate it in my garage with some effort, so I think there's some potential there. It's just a question of whether it can beat traditional metals economically, with a slight edge in aesthetic appeal for your high-end customers.
Yeah everything super easy when you control the entire process, from what apps you will see, to how you purchase them. There is no conscious decision to chose to pay with apple. You either purchase an apps subscription through apples payment gateway or not.

Alternative solution are convoluted because Apple makes it that way, it's by design. You are paying more than you need to, and developers get less then they should.

People complain about 1% surcharge on a visa, which is made clear before each purchase. Apple takes 30% and they hide the fact from consumers. But it's all so smooth, you hardly notice you're spending money it's so convenient. Is that so surprising when the company controlling the OS also controls how you pay for products they didnt make?
Probably because of status loss. Do they acknowledge your perceptiveness, intelligence and intellectual honesty after you demonstrate it each time? It would undermine their own status.

This is very interesting. The driver correctly paid attention to the Tesla driving and took over driving when the situation happened.
But the problem is that the Tesla autopilot was following too close during traffic.
Is the software faulty which means that Tesla is responsible?
Or that the driver should have took over earlier when (s)he noticed that his car was following too close so (s)he is responsible.
And if it is the 2nd, what is the point of the Tesla auto-follow when even when it works OK (before the accident), it breaks the law by following too close?
Nope, that's probably LiPo you're thinking of. LiFePO4 doesn't catch fire much.

Yup, though the minimum ‘buy in’ per unit without getting raked over the coals with high spread products is too high for many people. If you’re trying to set aside $20/wk, silver is terrible and good luck with Gold.

Hmm you're right that there's definitely more to the first function than coincidence. I dug a bit deeper and surprisingly when n is unsigned the function is still well defined and correct. [0] AFAIK clang will usually just treat a signed overflow as an unsigned overflow when optimizing as it simplifies things. So my bet would be that clang is just casting n to unsigned and performing some inductive reasoning similar to the proof I wrote below. Pretty impressive on the behalf of clang. [1]

[0]: I did the proof below for anyone interested:

int isEven(unsigned int n) {
return n == 0 || !isEven(n + 1);
}

# assumptions
MAX + 1 --> 0 # from the C standard
MAX is odd # true for most machines

# base case
isEven(0) --> True # trivial short circuit

# base case
isEven(MAX):
==> return MAX == 0 || !isEven(MAX+1) # MAX is not zero
==> return False || !isEven(MAX+1) # MAX + 1 rolls over
==> return False || !isEven(0)
==> return False || !True
==> return False || False
==> return False
==> isEven(MAX) --> False

# recursive steps
isEven(n) where 0 < n < MAX
==> return n == 0 || !isEven(n + 1) # n cannot be zero
==> return False || !isEven(n + 1) # False || anything is tautological
==> return !isEven(n + 1)

which will turn into an inverter chain of length MAX - n until you reach isEven(MAX)

- an odd length inverter chain is the same as a single inversion
- an even length inverter chain is the identity
(can be proven by induction trivially)

isEven(n) where 0 < n < MAX and n is even
==> return !isEven(n + 1) # MAX - n is odd, when n is even; replace with single inversion before isEven(MAX)
==> return !isEven(MAX)
==> !(False) --> True

isEven(n) where 0 < n < MAX and n is odd
==> return !isEven(n + 1) # MAX - n is even, when n is odd; replace with identity of isEven(MAX)
==> return isEven(MAX)
==> False --> False

All cases of n are accounted for so the function is correct (and equivalent to return n & 1 == 0).

It's part of the ongoing process, we can't skip to the final step. I think it is fair to rely on electricity and assume it will at least one day be green when thinking about green processes in totality, since some places are already generating green electricity. In my city we have a hydrogen plant powered mostly y solar that is feeding the steel mill, and this is just the beginning of exploring this process so it is bound to get more efficient.
no it does not suggest either of those things
I never tried their KN95s but their surgical masks are pretty great, the ear hook is thicker and softer with better elasticity and the nose metal band felt nice. I wouldn't go out of my way too much though.

This is me all the time haha sometimes I really am just "stupid" and the only one in the room without a clue, but many many times my stupidity has revealed no one really has any idea what they or the others are talking about.

I'm grateful to my parents or whatever it was that enabled me to not take myself too seriously and not care too much about people thinking I'm stupid, even at work, and even though it may cost me dearly in terms of career progression. (because I do think not all but many people who get ahead do so by very successfully avoiding being perceived as stupid, even if they are)
They would make so much money with a model 2 that they might be able to justify their valuation. I find it hard to believe that they won't eventually build it. Obviously not going to happen until factories are not at capacity with higher margin cars, but it seems likely to eventually happen.
Yeah, but if someone reading your quote wants to verify that it's an accurate quote and not taking it out of context, they have to dig up the source article and find the text you're quoting. The blog post is also mutable, which means its contents may change after being quoted. Tweets are immutable and always have a reliable link, with built-in quoting functionality.

The one caveat is that a tweet or account can be deleted, but that's true for blogs as well so I don't view that as a mark against Twitter here.
Interesting bug, but on reflection I find it more interesting that AWS WAF uses MySQL under the hood.

edit: I see WAF doesn't use MySQL - thanks. I've seen a few false positives in Akamai's SQL-in-URL detection so not surprising that AWS let something like this slip through.

Yes!

Everything that can be reduced to a word cloud will be reduced to a word cloud.

Then, those things that can't be reduced to a word cloud will be reduced anyways, and no one will know the better, since word cloud comparisons is what they'll check.

Place in a fire/water resistant bag 90% cash, 10% Bitcoin.

In the event of hyperinflation the Bitcoin will hopefully gain (or at least preserve value)-- and it can be transferred online, which the cash cannot. (And in the event of a total bitcoin collapse you still have 90%). Re-balance it once a year or so.

It doesn't take much to make missing out on the 0.5% interest rate of a high rate savings account into not much of a problem.
> BLAKE3 can be much faster than SHA-1, but only when it is computed in parallel with a large number of cores.

SIMD optimizations are arguably more important than multithreading. Take a look at these SUPERCOP benchmarks on a recent Intel CPU: https://bench.cr.yp.to/results-hash.html#amd64-pascalinspiro.... Those are all single-threaded measurements, and the SHA-1 implementation there is hardware-accelerated, but BLAKE3 is still almost 4x faster. That speedup comes from AVX-512 vector operations, which serial hashes like SHA-1 can't take (as much) advantage of. Not every caller will want to use the AVX-512 implementation (see "downclocking"), but even with AVX2 BLAKE3 would still be faster.

Multithreading is a nice option to have, and of course it looks great in benchmarks if the input is long enough. But general-purpose library APIs like `blake3::hash()` in Rust don't do multithreading by default. They only use SIMD optimizations by default.

> motivated engineers (culture!) in house able to refactor the vehicle software to support a new silicon configuration

I feel like this is overstated. I say this as someone who's done a fair whack porting work, compiling for a new platform isn't really that technically challenging - at least not at the talent you'd expect in the embedded space. Typically you'd have abstractions around maths, GPU compute, UI, rendering, etc. and a retargetable RTOS/kernel. That said, it's quite likely other auto-makers shot themselves in the foot by not having these abstractions.
Some pretty good deals here:

> Without interpolation, my understanding is there's likely a TON of aliasing in the raw output…

This is not correct, unfortunately. Aliasing is a time domain artifact, affected by the sample rate. The limited table size instead causes distortion, which affects the values.

If you ever run a bitcrusher plugin, you’ll see two sliders—one for bit depth, one for sample rate. Aliasing is affected by the sample rate. This is kind of like the other slider—the distortion slider in a bitcrusher plugin. Although it is like having not one bitcrusher, but many bitcrushers, reducing every signal inside the synthesizer to about 12 bits. Kind of. The distorted signal is evaluated at some sample rate, which also introduces aliasing (in addition to the distortion).

These effects are musically quite distinct. Aliasing is not generally harmonic, distortion generally can be (if you arrange it to be so).
Ah, so they're only a researcher as long as you want them to be? My point stands, attacking a researcher is not inherently anti-scientific, and attacking their research is... well, it's good science.

Yes it has happened or is nearly about to happen. FYI, the LR version of the Model 3 is $50k, about the same as the Mirai. By many metrics they've reached cost parity. Even if you angrily deny this, remember that EV are produced in larger quantities and benefit from greater economics of scale. It's pretty obvious the fuel cell cars are going to get a lot cheaper from here.

And as countries invest more into renewable they're are quickly running into a dilemma: Wind and solar are too unreliable to directly replace fossil fuels. This requires seasonal energy storage to solve, which as of today is only solvable by hydrogen energy storage: https://www.econstor.eu/bitstream/10419/236723/1/Ruhnau-and-...

In short, even EVs will be hydrogen powered to a large extent. You can easily imagine a kind of plug-in hydrogen car that matches EVs on efficiency in broad strokes.

Ultimately, this is not really a difference of opinion but rather a difference in understanding of the facts. You simply haven't realized that fuel cell cars are already here and have already solved the fundamental problems of green energy. Batteries cars have not, and barring a miracle battery discovery will not either.

> if cutting subscription fees on the Play Store forces Apple to cut their take on the App Store by half

Will it though? Or will the fee just become another "premium" differentiator between the two? The average Android phone sells for $250, but that hasn't discouraged Apple from pricing iPhones at 3-5x that. Other than strong government regulation (or the threat of it), I don't see Apple ever willingly reducing the App Store tax.
It’s not a matter of translation, it’s right there in the French (Harmonies économiques). He investigates why market societies tend to form into harmonious systems or organized wholes. He uses the word “harmony” extensively throughout the book and specifically in relation to the Pythagorean “harmony of the spheres”.

And, yes, with his magnum opus he does suddenly end up having principles much closer to those of Communist China. Are you offended? This quote of Bastiat might put things in perspective:

“It is as if the socialists were to accuse us of not wanting persons to eat because we do not want the state to raise grain.”

Markets may be the best way to serve the needs of society. But the point—even for Bastiat!—is to serve the needs of society. Is that shocking?

I'm more of an analytical person myself, and my non-technical co-founder at our startup is much like you described yourself. I built the tech in the early days (today I mostly manage the tech team). He was the sales person and used his impressive communication skills to win our first key accounts. One thing that he though me long ago is that there are several types of intelligence. It's not linear. People usually assume the analytical type of intelligence is the true type of intelligence. I find that to be inaccurate.

Compiler optimization is really annoying sometimes. It's allowed to assume that functions with the same name as standard library functions behave according to standard. They'll swap out printf calls for puts if they don't have a format. The compiler just knows it can do that. Sure, it optimizes things but it gets to the point the code no longer reflects what's written on the source file. Try to hook into printf and it won't work because it's not actually calling printf.

Even on freestanding environments they can and will generate calls to memcpy and memmove. That's insane...
Exactly, depending on the make/model that's either 3.0V, 2.8V or 2.5V lowest discharge limit. If you go under that you basically can not longer trust the cell integrity and should dispose of it (no matter what miracle workers on the web say, the copper in the cell will have gone into solution and it can be deposited anywhere at all, but never again in the same spot where it was supposed to be so you are essentially the proud owner of an incendiary with a random length fuse...).
I did this earlier this week. I was Slacking someone about a nuanced process they work with. I asked a couple of technical questions, and got some technical answers. I was MOSTLY certain I knew what was what - but I ended it with a Yes/No question, and he gave me a "Yes".

It is entirely possible there is additional information I should know, and he might have given a better answer if he had sought to understand my problem - but I'm not concerned about that!
Thanks for the suggestion. Just ordered along with Psycho Cybernetics which also gets a lot of recommendations
I do agree to some degree with that (I'm the OP not the siblings :)). We just have to define what small means. Netflix or Google are way up there in scale. In relation to them we are small. We also don't actually have microservices vs. what I'm reading about Netflix's architecture. We probably have "macroservices" in comparison with them but we definitely aren't one monolith. We got a bunch of "small monoliths" so to speak.

That said, we're not small either. In our niche, which you might recognize if I said more, we're the top solution customers choose (but I won't go into much more detail than that for obvious reasons).
