There are so many parts involved with a traditional engine and transmission. Living in Michigan, there are lots of companies building these individual parts. I know a guy who works at a place that builds springs for transmissions (https://www.pjws.com/our-products/)

Valvetrain parts, pistons, rings, crankshafts, starters, heads, oil pumps, exhaust manifolds, mufflers, fuel injectors, sensors...none of this stuff is needed on an electric car.

Hearing UAW members talk about the strike and concessions, they often say things like "they need to guarantee our jobs"...they know electric is coming.

At the extreme you have factory workers who are just in denial. "How can electricity have more power than gas?" You can show them a video of a Tesla P100 racing a <insert_fast_car> and they will tell you to your face that it's fake and they don't believe it.

The difference is that the rich person doesn't have to work. Their income is just the return on their investments. Meanwhile the poor person has to work 16 hour days to achieve an equivalent lifestyle. Okay, so they're paying the same amount of taxes, but is this a just way to organize society? What opportunity does the wage slave have to decrease their workload?

It's fine to have haves and have-nots, but the burden of supporting society should be equally borne, financially by those with financial means and laboriously by those putting in the labor. Regressive taxes force those without capital to pay twice.

I've wondered what the effect would be if the dump could force manufacturers to buy back broken appliances that are still under mandatory warranty.
I worked on Windows crash reporting in its early several years. One of the very hard problems was to figure out the “circumstances” that cause a crash. Actually, even defining what “a crash” is turns out to be hard. A single bug can manifest in all sorts of ways, especially if it’s something very low-level like a processor or code generation bug. Inferring the commonalities out of a bunch of stack dumps to make it visible to humans that there really is just one bug there is probably still a largely unsolved problem.
> "Dharma" also means 'truth'; the implication is that there is a kind of falsity in not being true to the identity you inherit, or that has been given to you (e.g. by military training).

I don't know why you've been downvoted. I've also watched this change unfold in big cities on the East and West Coast, most strongly among younger voters, since Bernie's candidacy in the 2016 election.
Wow, thank you very much for your extremely detailed answer. I'm looking to invest a little bit in things that I use every day (keyboard, chair) and your original post stuck out because you acknowledged it's possible to have a nice mechanical keyboard without breaking the bank.
We have a responsibility as a society to ensure that a framework exists (social safety nets, effective public policy) to allow someone to work towards finding purpose without starving or going homeless. If someone wants to cheat and call that a job guarantee, I’m fine with that. And in the long run, it’s cheaper than the alternative. It’s not just the moral thing to do, it’s compassionate and economically efficient.
This is a compelling mental model, but not practical — one person can't live expected values. If you want to actually realize expected values on options, the best option might be to become an accredited investor as fast as possible and invest in high-volatility companies :P
After thinking some, I realize streaming card data actually forces a player to share high value information whether they like it or not.

That is definitely not poker.

Bluff data is extremely high value! It is common to see a killer bluff shared as a sign of respect, for example. But, not sharing it is also common.

Others can profile a successful player and reduce the advantage they have in future games. Doing this old school, by reading people and deduction from known card data is an important skill.

Those who can do that, sans card data, are very potent players.

By streaming card data, players are forced to allow profiling with a precision and accessibility well beyond what would otherwise be possible, and all of it is accessible to any interested player! And archived (you all know it will be) for all time!

All of this not only devalues the game, makes it something not POKER in the most basic sense, even though the mechanics are the same, but devalues players too!

Just putting this here to augment my earlier comment.

And none of it is a slam against the tech. I do not mean that.

But, like bots, this is definitely one of those "just because we can, does not mean we should" type innovations.
Interesting question in Dan's footnotes:

"In the time that it takes a sophisticated attacker to find a hole in Azure that will cause an hour of disruption across 1% of VMs, that same attacker could probably completely take down ten unicorns for a much longer period of time. And yet, these attackers are hyper focused on the most hardened targets. Why is that?"

Isn’t a city walkable by definition? I am comparing it to a suburb obviously. It feels like they have to define what walkability is first. If there is any correlation it will not be on the overall score but on some aspects that make up the score.
With DynamoDB you can batch process table updates and selectively send WebSocket updates through API Gateway, vs Firestore which sends everything and can only process records individually in order. Firestore pricing is cheaper (18 cents per GB vs 25 cents for DDB) but the bandwidth/retrieval costs are higher.

I used firestore in production and it scaled beautifully to 10k concurrent users (many physical classrooms with all students connected, mainly during US school hours). My main issues were storage/bandwidth costs which were substantial for a relatively high traffic application using Firepad (https://firepad.io/), and the cold starts/monitoring for Firebase functions. The trade-off for our small startup was clearly time - with Firebase we could turn a hackathon's worth of time into a fully-managed service that required virtually zero maintenance, and customize it to our specific problem quite easily (albeit exposing much of our application logic as client JS), while handling a handful of backend processes like payment processing with Firebase functions.

Nowadays you can build the same fully-managed no-maintenance service on AWS and get access to a far greater range of services and data centers. However they have by no means tackled the web console user experience like Firebase consistently has.
Even coming from a place of no empathy for displaced workers lives, if we hang these people out to dry we will pay the price down the line.

If america had invested in a social safety net for the past 30-40 years, we might be in a different place. People would be ok with change because they'd know that society was going to have their back while they find a new career.

The orgo night performance is one of the big events of the semester. Every student knows when and where it is, so nobody will be surprised or pranked.

A lot of those fight scene coordinators from HK ended up coming to the US to advise Hollywood movies, my understanding is that it's definitively changed the quality of fight scenes (if you compare fight choreography in older movies vs the crazy stuff now).

So yea, it's looking like it's had a lot of success in theater but not in combat.
"two kinds of T's and D's which sound almost identical to me"

Sanskrit is a dead language. Nobody has used it as a spoken language for nearly a thousand years; and even those Sanskrit speakers a millennium ago were using the language only for specialist discourse, not as a mother-tongue. I'm saying it was already a dead language a thousand years ago.

We don't really know how English was pronounced in London, England as recently as 400 years ago. Shakespearean English might have sounded a bit like the accents of some relatively-isolated East-coast US communities (Amish?). We can only guess.

We have clerical Latin pronunciation, and legal Latin; the Latin pronunciation that I acquired was "school" Latin, which I think is the same as the pronunciation used by lawyers in anglo-saxon countries. but we don't know how Latin was pronounced in 50 BC (say). For ancient Etruscan, we can't really even guess.

There is no correct pronunciation for Sanskrit.

This is pretty cool. Always interesting to see how things eventually become mainstream whereas origins go back decades, sometimes more.
There's an extremely large difference between tricking someone into thinking they're working for the other team by grafting on a pre-calculated memory of them being a Chinese agent for the last 20 years rather than ... making their finger move and saying that gave them a memory of their finger moving.
Giving an exemption for necessities turns VAT into a Pigovian tax on luxuries. In effect, this is an attempt to modify the behaviour of the poor and so it can be construed as a form of social engineering which exempts the rich. Given that some people view poverty as a moral failing, I think this is a bad thing.

In reality, it doesn’t even work. Poor people spend money on luxuries in order to gain status which they need to attract a partner. Rich people don’t need to do to spend their money to gain status since they already have it by virtue of being rich.

It's also a fact of life that that economics dictates where effort is spent. If I port all my OpenGL code to Metal, that's a big undertaking in both time and money. And what do I gain? Nothing. The program will render the same views both before and after the change. It's not directly adding value. So why would I bother?

Also bear in mind that I currently support the application on Windows, Linux, FreeBSD and MacOS. OpenGL rendering works the same on all four platforms, and I have a unified cross-platform codebase which compiles without any trouble on all of them. If I switch to Metal, that's going to mean dropping all the other platforms which use OpenGL. Or it's going to mean having a separate MacOS-specific implementation for Metal. Dropping the other platforms is unacceptable.

MacOS is a niche. Windows is a bigger market. Depending on the application, Linux might be as well. Consider that Windows, Linux, and even FreeBSD can support beefy modern GPUs while MacOS is quite limited in the on-board GPUs on its laptops and other systems. When push comes to shove, MacOS is the platform which I will drop first. It's already got the oldest and most limited OpenGL implementation and the poorest hardware, and this makes it the worst choice for running my application in the first place.

If Apple want to retain developers like me, then they can provide a first-class current OpenGL implementation based on top of Metal. And then they can also provide a high-quality Vulkan implementation also based on top of Metal (or the other way around). Because if I do upgrade, I'll be upgrading to Vulkan on all four platforms, not to Metal.
The stuff they're doing is sort of similar to hypnosis, where you have people who are open to suggestion carry out the suggestions of someone confident, and the best way to exude perfect confidence is to actually believe you have powers. That's what I imagine at least.
Not sure why socialism has such a bad rap. The opposite is asocialism (a society based on "avoiding social interaction; inconsiderate of or hostile to others."), which can't be good for any society.

They’re striking because they believe they should be paid more considering GM is making billions in profits. Concessions were made when the economy was in trouble, and the union wants those concessions reversed. Why is this unreasonable?

I understand that labor unions aren’t well understood in America, but this is what they’re for: to get a better deal from a corporation for their labor. The alternative is what used to happens centuries ago: violent civil unrest over labor conflicts. No one wants that.

“Just fire them” is a grossly inaccurate solution for a complex problem.
I agree with the parent insofar as the title is misleading. I immediately assumed he had died from the title. It's heavily implicit.

I also think it's pretty clear that it was a suicide attempt, and, though I could be wrong, the article itself describes it as a suicide attempt, so they've already made that judgement when choosing the title. Of course, regardless of whether or not it was a suicide attempt, the information that he didn't kill himself could be conveyed in the title.
Most major vendors did use it, and likely still do internally, but with federation turned off.

If you have a billion “users” using a working chat system and the concern is “with federation they can chat with outsiders and we can bleed users” you don’t just drop the whole thing, you turn off federation and prevent third party client logins.

Oh yes I agree, and if some enterprising engineer wanted to buy the trademark and start producing them again I'm sure they'd use a servo and a microcontroller to achieve the same effect.

The design of the toaster reminds me of the design of the first transistor radio which ingeniously needed just four transistors to work. Nowadays that engineering effort would be a complete waste of time. It's sad in a way that that sort of craft has been lost, but it's largely redundant now.
Many of those "bugs" were probably just accepted engineering tradeoffs for reduced number of transistors.

When you have 3218 transistors, you don't make perfect features. The same thing happens when you have a very limited total instruction count to implement software.
The reduction in parts and need for workers on EV’s is nothing compared to when Bus2Bus transition (without stops) will come.

>>If there is any information domain were it’s harder to figure out the real truth than current US politics, it’s “nutrition science”

I recently dug out some original USDA documents from the 19th century to research[1] the origins of nutritional science in the US. W. O. Atwater, the guy who introduced things like Calories (equal to kcal), macros, and "dietetics" has had a huge impact on nutritional science, including modern food labelling and things like the simplified conversion of fat to 9 Calories/gram and protein/carbs to 4 Calories/gram.
Atwater himself was very much influenced to introduce these to the American public by his German professors (he did a postdoc there), who were themselves looking into making nutrition "efficient - for cattle and humans alike.

I found the history quite fascinating, it gets to the "origins" of the idea of quantifying food.

I was just benchmarking routers in VM. I also tested Openvpn vs Wireguard. Results:

Openwrt 18.06.4 32-bit
wireguard: 645 Mbit/s ping 1.1ms
openvpn: 164 Mbit/s ping 1.2ms

Openwrt 19 (snapshot r11159) 64-bit:
wireguard: 1.16 Gbit/s ping 1.1ms
openvpn: 230 Mbit/s ping 1.2ms

pfsense 2.4.4-p3 (amd64):
openvpn: 115 Mbit/s ping 1.2ms

It was tested by moving traffic between two virtual bridges, Debian>router>Debian, on KVM (libvirt), CPU E3-1270, kernel:
4.19.0-4-amd64 #1 SMP Debian 4.19.28-2 (2019-03-15) x86_64

1 core, 2GB per VM

iperf3 -t 60

Settings:
Wireguard: defaults
OpenVPN: no compression, udp, tun, defaults

I would also note that I setting wg took about 5-10 minutes while setting openvpn took about an hour.
I've long put off having a food and symptom journal, because I'm pretty disorganized, but I will take your advice serious. Can I ask how you exactly correlate the symptoms with your food intake? From what I've read the digestive system takes max 48 hours from in to out.

In other word, "real" learning is hard, it takes work, it's not fun. The problem is that "the algorithms" (whatever recommendation ML algorithm YouTube has) works so damned well we are sucked into this endless shallow junkfood dopamine loop of videos that give us just the right amount of dopamine to click on the next one.

I'm not intimately familiar with Fischer-Tropsch, but reading the list of existing plants on the wikipedia page https://en.wikipedia.org/wiki/Fischer–Tropsch_process#Commer...

Virtually all of them are producing synthetic fuel using other fossil fuels. E.g. natural gas or coal. One is using pulp/paper waste, and the other is using a combination of natural gas and landfill gas.

So while the process promises to convert "a mixture of carbon monoxide and hydrogen into liquid hydrocarbons" it does not seem that anybody is doing that.

You are totally right that there is nothing wrong with liquid hydrocarbon fuels, as long as they are sourced from clean energy, but the fact that nobody is doing it even at a small scale seems to indicate to me that it's not (yet?) viable for some reason.
This website makes me worried about the future of representing text on the web:

I think this list makes no sense unless it is made into a wiki of some sort with community contributions from hundreds of people.

Under "Physics", he has a sub-heading "Increasing Iteration Speed of Experimental Physics". This section mentions one random startup. Yet CERN has hundreds of people actively working on this topic for decades.

They invented, built and implemented the world's first capacitive touch screen control system in the period 1972-1976 specifically to answer this need. That's just one example off the top of my head.
If they don't find anything related, tangential etc, nobody. That's the reality we are facing off.

In Spain several coal mines shut off. The initial idea was to just retire this people. In some cases they made them hop trough some recolocation programs.

IMO retiring people is just cheaper. The administrative overhead of managing this people is not worth the cost.
HIView and HIWindow were added, if I recall correctly, because it allowed other toolkits (tk, Qt (who only recently moved off this), etc) to draw the native look “properly”. It was never actually up to date or well documented, and they kept it around just so the OS didn’t look so totally bizarre as you moved through it (like you see on Windows).

Bolting on Retina support to that is such a no-brainer that I hesitate to call it adding features - that was table stakes in making sure the switch to retina didn’t look like total ass.

None of this stuff ever changed how Carbon was deprecated. People just sat around not listening to Apple, and then the last two years the bigger GUI toolkits finally did the work to transition properly.
