As a person who has written tons of machine and assembly code and dealt with decades of working directly with the cpu: this is a well written and accurate article.
I'm not talking about doing biomed better than Boston, or chemistry better than the Gulf Coast, or manufacturing better than the Midwest. New Jersey (AT&T / Bell Labs) used to be the place to do telecommunications. Silicon Valley is not in the telecommunications industry, it's in the Internet industry. I'm talking about which industries will replace BioMed, chemistry, and manufacturing.

Silicon Valley is really good at 3 things:

1.) Eating our old.

2.) Replacing humans with computers.

3.) Thinking we know better than everyone else.

Makes us kind of insufferable, but that's precisely the mindset you need when your goal is to replace large segments of the economy with machines and take all the spoils for yourself (and your co-conspirators). If you're going to play nice and respect established wisdom, you'll never even bother embarking on such a project. SV's greatest strength is the large number of people who can be convinced to apply their technical knowledge to a project that sounds crazy and doesn't exist yet.

You probably had pancakes on the plate and some of the sugar got on the sausages during sprinkling.

We watched this during film school in college. We were told it was one of Adolf Hitler's favorite movies by one of his favorite Directors, Fritz Lang. Watching that movie having been told it was Hitler's favorite, was eerie to say the least.

Electron maintainer here, although we _also_ support arm64 for Windows. Apple silicon support was driven from the beginning as a priority, it was obvious that it was the future of macOS and without direct support you'd be left behind. arm64 on Windows is barely supported by anything, let alone msft itself...

Also Apple did a fantastic job with early engagement for Apple silicon development, even going as far as to assist with code changes / patches early on.

NKLA has nothing now, what we're left with is evidence of the new era of 'RobinHood' traders et. al. thinking they're on to something, or not realizing that it's really over, keeping some kind of valuation in place.

We may be in a new era of equities, where the unfortunately under-informed masses are able to really move the needle on a lot of stocks, throwing all sorts of value-trading strategies out the window.

In this kind of market, all you need is a Donald Trumpish like figure and nothing else to keep the fake-valuation going on forever.

Honestly, if Trump were smart he should literally wrap up his businesses in some kind of non-transparent black box, IPO the meta entity right now and get his zillions of 'backers' to hype up is stock perpetually.
Does hard rock mining release CO2 inherently or does it just require energy? If it's just energy, which seems like to me, energy might be supplied by hydrogen or other CO2-free sources.

Water use compared to personal use isn't that important. Most water used by an industrial society is used in agriculture and that's probably true for Chile.

I think what's really going on here is that the current methods of producing lithium are really not very environmentally harmful.

Agreed. The negative impact of mining generally comes from companies incentivized to cut corners. Strong regulations requiring waste be contained, etc, are what needed. The worst problem is that large companies do cost arbitrage across the world, incentivizing countries to lower their standards - why all the "rare earth" mining went to China when they were willing cut corners and then the West screamed bloody murder when China stopped wanting to be the world's garbage dump.
Theranos at least fell apart once the WSJ put out extremely strong evidence that it was fradulent. The innovative tech that Nikola claimed to have was shown to be fradulent months ago, but they're still worth billions of dollars.

>>The advantage of synchronous test taking is that everyone is exposed to the problem set at the same time. The obvious cheat with asynchronous test taking would be for one person to volunteer to take the test early and then send the questions to their peers,

This problem has been largely solved for a long time, because as you noted it is generally impossible to give a test to EVERYONE at the same time.

Thus properly written tests will draw a random selection of questions from a larger pool, the ratio between Pool:Questions the better the security. (i.e a 25 question exam using a 50 question pool is not as secure as a 25 question exam using a 200 question pool)

This method is also used for standardized tests given at the same time, as it cuts out the problem of shoulder surfing or other in-person cheating methods.

>I'm kind of wondering how scalable the performance increases they made here are

It's a good question and really only time will tell, but this same comment was made about these chips in the iPhone: "impressive yes, but would they be able to scale up to power a laptop?" A lot of people said no back then, and yet here we are.

Apple's not stupid and they're not going to slap Intel in the face like this if they're not 100% sure they won't need them again in the future. I'd be willing to bet they already know the answer to these questions (and likely even have 32/64GB M1s running in their labs). There's just no way they'd go into something like this blindly.
https://decodechess.com/ does that kind of thing.
The way I see it: the linear algebra parts are just optimizations.

You can probably??? write a raytracer using Trig alone: it just means that you'll be using sin/cos on angles instead of "short-cutting" with a dot-product to determine normal vectors.

Hmmm... well... maybe the concept of dot-products and orthogonal vectors will help. So Linear Algebra probably will make things easier if you studied that too... but I still think its kinda optional.
> Shortening the wire also lowers latency between all the various on board devices, so communicating everywhere is faster.

A maximum of a few nanoseconds. Not much in comparison to an overall memory system latency.

> Shorten the wire to memory cells and not only can you make signaling faster and run the memory at faster clock speed but you can do it with less accessory hardware for signal conditioning and error correction, which saves complexity and power.

You cannot run away from that with just shorter PCB distance. The circuitry for link training is mandated by the standard.

You will need a redesigned memory standard for that.
Did you get tested and verify it was COVID? Just making sure because sometimes commenters claim they had it but never actually got tested haha.
> He's both right and wrong

That's my main impression from a lot of texts written by Wells about the "modern" world. Reading them, it's easy not only to recognize that he had wrong predictions, but even that he didn't have a good enough idea about the world of his time. Interestingly enough, in spite of that, some of his observation and conclusions based on them, when they were correct as far as his myopic view reached, can be indeed lucid.

Still, I'm very sure that he's not at all unique, neither in his time nor in our current. Most of us are myopic as soon as we start to write about the "big" topics, and even more when our political biases are to be present. In many decades, whatever we saw wrong will be much more obvious.

>Keenforms started as an idea and a side project. It took more than 3 years of evenings and weekends to get something worth releasing.

I've also worked on forms with a rule engine for nearly 3 years almost full-time (started in 2017). It's a hard problem. There are some commercial no-code and low-code solutions.

For forms with a rule engine you really want to have some debugger included that visualizes the data flow. Somehow people think one just has to author rules and then it's finished. And errors never happen.

I take a lot of inspiration by the work of Chris Granger, Bret Victor, and the "Future of Coding" community. But also the UI/UX of Notion and ObservableHQ.

I do find that physical exercise and exhaustion are helpful for good sleep. If I lay down and "can't fall asleep", I typically get up and keep working until I can't help but fall asleep.
The decibel is defined as a tenth of the log10 of power, so power doubles every ~3dB. Amplitude and pressure are proportional to the root of power, so amplitude doubles every ~6db. Loudness is roughly proportional to the root of amplitude so it doubles every ~9dB.

This leads to confusion when people don't specify which quantity they are comparing.
WeWork and Theranos were priced badly in private markets, which is a completely different kind of fraud/misleading than after the IPO, when it's a matter of public communications.

Before IPO, I think almost every fraud is unique, even if they have common themes ... but after IPO I think it's more similar to just hype-man using PR and media to keep retail investors avoiding the reality of the balance sheet.
Funny you mention that [0] as I'm actually in Ireland so it was 9:20 PM for me. I presume you're on the US East Coast? Being able to do one of these at a specified minute would be impressive though (of course you could just _only_ try during that minute every day and you'd eventually get it).

You can do that with ZFS too, at least for mirrored sets (i.e. RAID10). It's possible to remove a vdev, and the pool will migrate the data to the remaining vdevs.
> Lithium is crucial for the transition to renewables, but mining it has been environmentally costly.

From my limited insight into the issue, I got the impression, that the mining of lithium in itself isn't the problem, but that is being done in the cheapest ways. For example, when mining it from water, the water is being evaporated and the wind carries it to other places. But shouldn't it be possible to required miners by law to pump as much water into the ground as they pump out of it?

That would be more expensive, but as far as I understand it, it should reduce the environmental effects significantly.

My hot take on this is that java checked exceptions are bad because their design predates java generics. Because of the lack of generics, authors of packages such as java.io had to create god-types of exceptions for their general interfaces to throw. A good example is

public int java.io.Reader.read() throws IOException

As I see it, the purpose of checked exceptions was to allow declaring expected failure modes in the function signature, so that the programmer (and the compiler!) could check against them - but when my StringReader declares itself capable of throwing an SSLException (subclass of IOException), this benefit is lost. Instead, I must rely on other sources to determine which errors may actually occur, and which I can't do anything about - and the latter I must swallow or pollute all of my package's function signatures with. If the Reader interface had instead been generic

java.io.Reader<T extends Throwable>

read() could be declared as

public int read() throws T

This would rescue much, and is something that could be done in modern java; but by the time generics were introduced, all the core packages like java.io were written, and the patterns for how to deal with checked exceptions were set.

So he warmly welcomes the elimination of trade barriers, predicts it will create a large peasant class, then aggressively undermines a proposal to up-skill students by saying it is too expensive.

No one is ever going to come out and say "I hate poor people, do not design systems to empower them." They say things like "do X which will hurt poor people but also do Y to help them." X always happens before Y, and when the time to implement Y comes it is always too expensive.

Look at the 2008 financial crisis: banks bailed out early on, 40 million people experienced foreclosure. Look at the CARES act. Now that the market has rebounded, there will be no support for people facing eviction.

nah, we just need valuations another order of magnitude higher in more companies.

when the market is flooded with money the price of everything goes higher because there is nothing else to buy. that's literally what "inflation linked assets" means. Like most financial terms, it is a euphemism where the financial professional tries to keep a straight face for the longest time.

Is COVID real? Yes! Is is really that bad as everyone makes it out to be? No! If it was that deadly of a virus, 9 out of 10 people would be dead by now. Do you need a vaccine? Nope, unless you want to take one and die. I have only been sick one time, and that was during Dec to Feb of 2019 when every human being was exposed to COVID. Have I wore a mask this entire time? No! Have I went and got tested? No! Will I go get tested? No! If man would quit playing GOD, there would be no diseases to fabricate vaccines for people to take. Ultimately it merely becomes a money racket to align the rich pharmaceutical companies with power and control. And as for cancer, that's man made and there's a cure for that as well.

Weird mix of sugarcoating and needlessly dividing people. Not you, but the terms.
Oh that is very much something they could do, but given the fact that they control the OS completely it would be very interesting to keep the on chip and off chip and enable the software to support understanding which is RAM is where and allow the application developers to tweak items. For example lets say you are editing a very large 8K stream and you tell the app, hey load this video into RAM. You could put the part that is in the current edit window in the on chip RAM and feed the rest of the video into that RAM as the editor moves forward from the 2nd level RAM. There are some interesting possibilities here.

Also from the ASIC yield view it allows for some interesting binning of chips. Let's say the M2 has 32MB on chip plus an off chip memory controller. They could use the ones that pass in the high end, then once that fail a memory test as 16MB on a laptop, etc. Part of keeping ASIC cost down is building the exact same thing and binning the chips in to devices based on yield.
> Preventing repair (as Apple does) generates more e-waste. There really is no way around that fact.

There are plenty of ways around that fact.

Preventing repair while changing nothing else generates more e-waste. But that's not what Apple does.

If you prevent repair in order to also do any or all of the following things at the same time enough, the result is less e-waste than if you didn't prevent repair:

- Use less environmentally harmful materials (e.g. on-board sockets, larger PCBs etc)

- Make the device last longer before it needs repair (reliability, longevity)

- Make the device easier to recycle

> Reuse and repair is FAR superior to recycle

It's a good goal, but it's only superior for sure if everything else is able to be kept the same to make it possible.

Some things really are better for the environment melted down and ground down and then rebuilt from scratch. I'm guessing big old servers running 24x7 are in this category: Recycling the materials into new computers takes a lot of energy, but just running the old server takes a huge amount of energy over its life compared with the newer, faster, more efficient ones you could make from the same materials. I would be surprised if not recycling was less harmful than recycling.

> What good does it do? They are still harming the environment.

When saying Apple should change they way they manufacture to be more like other manufacturers for environmental benefit, Apple being rated number 1 tells you that the advice is probably incorrect, as following it would probably cause more environmental harm not less.

All this tells me is that Rust gives crappy useless stack traces that include noise of functions handling the panic itself and the creation of the stack trace, and this has poisoned your view of stack traces.

Why can't Rust produce much more readable, concise, and useful stack traces like Python, that include the function name, file name, and line number of each step of the stack?
