In addition to sibling comments, two more oddballs are MSP430 floats and DSPs.

MSP430-style floats are common in industrial automation and such, since many sensors either use or used to use MSP430s to collect data. And, of course, in that field, legacy carries more inertia than a 50,000-ton press....

Newer DSPs tend to use IEEE-754 floats, but this was not always the case. Older DSPs used every trick in the book to go faster, and "compatibility with standard floating-point formats" was never in their product requirements. So you can guess at what manner of horrors came out of that! Fortunately, their customers are mostly the sort of people who (1) didn't mind changing to standard floats, since it's not like things were stable before; and (2) are very, very comfortable writing this stuff directly in assembly. So they definitely know whether their architecture has an instruction to take the absolute value, needs a short branching program, or just needs a single bit-operation.
It's wild how invasive creeping bellflower is. It's pretty purple flower, so people think that it's just another flower which is part of why it has staying power. The rest of it is the fact that each plant can generate 15,000 seeds, can spread through a root system under the soil, and can regenerate from fragments of the root. If you have it, you'll have to keep digging it up every year for some time.

Green hydrogen is being produced today at around $2.30/kg at Ningxia in China. The actual price they quote is $0.20 per cubic meter, [here](https://www.upstreamonline.com/energy-transition/chinese-com...), which if you work backwards from a density of 0.089kg/m^3 at SSL conditions give roughly $2.24 per kg. That's a 200MW facility; a much larger 2.1 GW facility has just started construction in Inner Mongolia and is expected to come online in 2023. It's possible this facility reaches price parity with grey H2 just based on economies of scale.

Also, 33kWh is the upper bound for the energy you get out of hydrogen. Practically, a fuel cell will get 60-70% of that, depending on the type. Electrolysis is around 90% efficient today, depending on the type of electrolyzer, and how you measure. SOECs can get better than 100% apparent efficiency by utilizing waste heat.

Most sources I've seen for green H2 put the threshold for economic viability at around 2c per kWh. At that price you're still more expensive than grey, but you're at least within spitting distance, and this seems to line up with the Chinese figures.
I think the EV Hummer is going to be interesting test case. It's something like 9 thousand pounds and a thousand horsepower, 0-60 time of 3.5 seconds.

Society generally accepts small, fast sports cars and slow, heavy trucks, but fast, heavy trucks are something new. Sports cars are accepted I think in part because they're not designed like battering rams. If a sports car is in a wreck it'll probably take severe damage, and the driver is at a pretty high risk of injury too even if the car has sophisticated safety features. With this new Hummer, someone could sneeze and plow through three lanes of traffic and come out unscathed. The consequences of risky behavior are falling disproportionatly on the people who don't drive big trucks.

(This argument applies also to EVs like the Model S to a somewhat lesser degree. They're also fast and heavy, but they at least don't look like something you'd smash through a roadblock in some action movie with, so they kind of get a free pass.)

Requiring a CDL for certain vehicles that are heavier, more powerful, and with high risk of damage or injury to others seems like a reasonable option to me.
>For the cantilever design: it is already used by Prusa 3D printers which are well regarded (in the field of amateur 3D printing) so I do not think this is an issue for the targeted accuracy which is typically 10 to 50 micrometers.

3d printers don't have forces pushing back on the print head, nor the vibration from a cutting tool to deal with.

This design might work ok for 3d printing, or laser cutting, or anything else where no contact between the working head and the material occurs.

As far as accuracy and repeatability, it's going to be about as good as the average 3d printer design. It's a nifty idea for a system, but it's only a decent machine for cutting if it's scaled up massively and built of cast iron or similar materials.

I think it's sort of a type of double standard where you say that "your side" is only acting out of fear/confusion/emotion/ignorance/etc but the "other side" has a long, complicated game plan that is surely going to fail, and everything they do is committed towards their bad plan, so you feel the need to "call them out" on it. You can't really "call someone out" in the same way if they are just confused or upset, rather than evil.

Destroying TSMC fabs is in neither US nor PRC or Taiwan's interest, it's the only point of consensus and mexican standoff leverage between all parties that prevents a TW war from escalating too far. IMO US and PRC would rather bargain some sort of sharing agreement over TSMC even in event of military actions in exchange for not glassing TW than have everyone lose access to the fabs.

> imagine what it will be like to cut current supplies by another 40-50%

And despite everyone's aforementioned desire to preserve TSMC, ultimately this is still a trivial amount if you consider that the East Asian semi supply chain accounts for 75% of global IC share and is completely within PRC missile range if there was ever an expansive east Asian theatre over Taiwan. Losing TSMC in war over TW will set the world back 1-2 nodes and 10 years, losing regional fabs and supply chains (in SK or JP) in a broader war over TW will knock out decades worth of capex. Global semiconductor industry is a 500B market, trillions in terms of industries affected, most of which benefits the west. PRC has massively more leverage in semi mutually assured destruction, so much so that TSMC is ultimately expendable if PRC is ever forced to act upon TW, because losing TSMC doesn't even scratch the surface of semi disruption PRC can cause US/West, who again are disproportionate beneficiaries of current IC status quo.
> Traditionally, that has been in the form of fuel taxes.

The fuel tax has three major issues:

- the US one is a flat fee not indexed to inflation and has not increased since 1993, so the purchase power of it has gone down as well as its percentage of the sale price since gas prices have risen a lot since 1993. no politician at the federal level is brazen enough to suggest actually raising the gas tax and hitting Americans in the pocketbook. In fact the fury is so bad that Massachusetts voters repealed inflation indexing for its state gas tax, because everyone wants the better roads but no one wants to pay for them.

- the wear and tear on the roads is not linear with weight. The federal government estimates that one 18-wheeler causes the same amount of road damage as 9,600 cars. The relationship between fuel price and road damage (which is what ultimately impacts the maintenance expense) is not reflected in a gas price even if trucks are less fuel efficient.

- the decrease in gasoline needed. Fuel efficiency is very good, and transitioning away from fossil fuels even better, but those cars and trucks will end up paying less money while causing the same amount of road damage as they did before.

Good point.

You can send in your activated cartridge to sawstop - if it was skin activated then they may replace it for free.

If you are concerned about a trip you can touch blade to piece with saw off and it'll tell you if would have tripped. Or do a first cut with system off. Or if you have a wet piece turn it off.

That said if you have a nail or something in piece there are situations that could trip it for sure.

> Do you have any recommendations how long to prep for a leetcode style interview?

This entirely depends on your starting level on Data Structures & Algorithms, and how much time you can set aside per week, but be warned though: it is a grind - I had to give up other hobbies for 6 close to 2 months (I'm not very smart, and I wasn't aiming for the most challenging tier of interviewers, YMMV). Once you've done enough questions (dozens or low hundreds), you start to recognize patterns and get a hunches for avenues to explore when solving.

I'd recommend "Cracking the Coding Interview" book, leetcode and/or hackerrank for practice as well as searching for YouTube for specific algorithms/structures that you find challenging - I struggled a bit with dynamic programming at first (speaking of which, know the class of questions your target companies ask so you don't waste effort). You can monitor your progress by timing yourself on how long it will take you to complete "easy" or "medium" (depending on competitiveness of company you're shooting for, you can time 1 easy + 1 medium, or 2 mediums, or 1 hard + 1 medium within about 50 minutes).
Did you think that said FCC?
I’m looking at those numbers and the worst was Peru - 0.5% excess deaths.

Am I the only one whos just thinking none of this matters?

The reality is Sweden is doing an amazing job if there’s no lockdowns. Those lockdowns led to a massive increase in suicides[1], economic damage[2], inflation[3], massive increase in drug abuse[4], lost years in education[5].

Frankly, it’s hard to imagine this virus would cause more harm. Especially if the worst case is 0.5% excess deaths (almost exclusively from people near end of life). What’s the damage in years of education lost, the drug abuse, homelessness, inflation pricing out homes for those who can work...

long-term I expect Sweden will see lower deaths than any of the countries that locked down.

Oh I see, that makes more sense. I'll look closer at the data, still not sure I'm 100% following.

Just to share what confused me, I read "fatality rate" as the rate at which a struct pedestrial is killed, so I couldn't wrap my head around why that mattered to the point at hand.
His difficulties are characteristic of someone not seeking solutions to actual daily engineering problems, and instead getting lost in a maze of language lawyering.

If you approach features in terms of how they can be useful when coding, almost all of his difficulties never arise, or are easily sidestepped. For working coders that becomes second nature.

Fake news, but we knew that since the article is from the Guardian.

There are many hints and anecdotal pieces of info that indicate that virus escaped from there. There isn't much concrete evidence because the CCP destroyed evidence, delayed the investigation, mislead investigators and didn't allow full access to almost anyone.
This just comes off as a “I can see the problems with that approach from 40 years ago because my hindsight is 20/20” kind of statement.

It’s also worth considering that the cost of living in the US has been lowered because China has been the factory for our WalMart / Target / IKEA goods. If we didn’t open up China to the US / WTO markets, the world would be a very different place and that counterfactual is pretty difficult to calculate.

"Bosch came out with a superior design that doesn't use a brake at all, but were barred from selling it in the US because it infringed SawStop's patents."

The design was not superior and the infringement was not based on a brake or lack of one. The infringement was because of copy of the skin contact sensing / blade drop technology as what were called underlying elements. I think the case may still be ongoing though? This one went a long while.

Which is why good analysis looks at excess deaths (ie, compared to the average over the last few years).

By that comparison Sweden has done very badly compared to its peers. See https://ourworldindata.org/grapher/excess-mortality-p-scores...

As this very article says:

However, Dr Bhatt, the University of Copenhagen professor, is keen to point out that for all of its successes, Sweden saw more Covid fatalities than its Nordic neighbours who took a more interventionist approach.

The death rate was between three and four times that of Denmark, and nearly 10 times those of Finland and Norway - suggesting Swedes died that didn’t need to.

Article's subtitle: "Laurent Binet’s latest book, “Civilizations,” imagines what might have been if the Incas invaded Europe in the 16th century."

First thing that came to mind when I read this was Guns, Germs, and Steel. It was the inspiration for the novel:

“In it Diamond wonders why it was Pizarro who came to capture Atahualpa in Peru and not Atahualpa who came to capture Charles V in Spain,” Binet said. “That sentence was a real trigger for me, and I thought: Why not tell that story instead?”
Policies are supposed to be (and inevitably are) designed based on a balance between empirical analysis of their likely effects and a more holistic analysis of what people want. The holistic factors determine what kinds of empirical evidence are relevant and how much of it is required. If someone tells you they've designed a policy based purely on "science" or "data", they've baked in some implicit value judgments, and you've gotta understand what they are to properly evaluate the policy.

alas facebook archived their "flick" time unit, which promised to unify this all. ;) https://github.com/facebookarchive/Flicks

even this was an appropximation though:

> NTSC IS NOT EXPLICITLY SUPPORTED IN ALL OF ITS SUBTLE NUANCES, BUT: The NTSC variations (~23.976, ~29.97, etc) are approximately defined as 24 1000/1001 and 30 * 1000/1001, etc. These can be represented exactly in flicks, but 1/1000 divisions are not available.*

> Many folks online have pointed out that NTSC technically has a variable frame rate, and that this is handled correctly in other media playback libraries such as QuickTime. The goal of flicks is to provide a simple, convenient std::chrono::duration to work with when writing code that works with simulation and time in media, but not explicitly to handle complex variable-rate playback scenarios. So we'll stick with the 1000/1001 approximations, and leave it at that!

Are you insane? Going along with the courts is usually not in your best interests. Hiding the evidence and never going to trial certainly is. If we are talking about information that you definitely need to hide then the penalty for your obstruction of justice, whatever its form, will be a rounding error on your sentence. If it does not definitely need to be hidden then should they find out they are unlikely to charge you.

Absolutely not - no where did I say that anyone should be forced to buy the saw.

I was merely pointing out that saying you would never buy a sawstop for whatever crazy reason (ie, other companies wouldn't pay them the $3-$10 or whatever) seems a bit ridiculous.

If you have a fair number of folks using the saw, have them touch materials to saw first with saw off to get a read on it or list the ones not recommended.

> fuel price and road damage is not reflected in a gas price even if trucks are less fuel efficient

It’s almost like you’re saying a fuel tax shouldn’t incentivize fuel efficiency. I am saying it should. Broadly, heavier vehicles do definitely burn more fuel, hence why diesels are more prevalent with heavier workloads.
Uhh - the manual will tell you not to cut aluminum, very wet wood etc with sawstop feature on.

If you turn off feature you are back to your regular saw - hopefully you use a stick etc in all cases because as you note replacing cartridges is expensive.

One thing I like, it'll put feature back on automatically for the next time machine gets turned on.

> because heavier vehicles cause more wear and tear for roads

That is true, the fatigue damage to the road goes up as the cube of the weight. What this means is that cars don't cause much fatigue damage to the roads - it's the trucks that do. A semi loaded to the legal limit causes 9,000 times as much damage as a car.

Really, the heavy loads need to go by rail, not highway.
Unwilling humans, and humans getting paid less than the cost of their legal ruin, are a liability to criminal enterprises. Those humans are at risk of tattling. Yes, such enterprises can invest in buying prosecutors, prison guards, prisoners, etc. to punish tattle tales -- but robots don't talk. Sure, maybe parts can get traced, but it's bound to be easier to "secure" a part supply (make them yourself if you have to) than to "secure" your human liabilities.

What's a bit disgusting is that yes the privileged nature of thinking is of course accurate, and all the time before the 19th century was very oppressive to the women and other groups, but that's not quite relevant to the story of walking being good for thought.
