Buying and selling stock doesn't create any boost to the economy. But it is the engine for two very powerful positive effects:

(1) If a person can start a successful new company, they get assets (stocks) that they can sell for money. This creates an extra incentive to start new companies.

(2) Large investors (eg, Buffet-sized) have an incentive to buy significant stakes in companies and improve their management, then sell them to long-term investors. Being able to sell shares for a profit after improving the company creates an incentive to improve companies and then move on to the next one.

And there are a couple of other things like that. So stock trading doesn't in itself do anything useful for the economy but it is the point in time where past decisions that did boost the economy are realised as a profit in dollars. It also creates a barometer for measuring what people with money think about a company's chances, which is useful information and hard to get otherwise.

There is also a very helpful long-term effect where people who can accurately predict the future make money from stock trading, which means over time (in theory) company ownership becomes biased towards excellent long term planners.

Hate to be the naysayer, but last mile is going to be tricky. 10 mins from Palo Alto to SF sounds fantastic. But if it takes you 15 mins to get from home to the flight, and 15 mins from flight to wherever you need to be in SF, then the total of 40 mins doesn't sound so great when you factor in the price.
How standard is it? As far as I know among databases MS SQL and Oracle do this but do other commercial databases do this as well?
Many poor countries have free market medicine: the number of medical providers is not constrained by a guild system; new drugs and medical procedures are regulated lightly if at all; pricing is completely transparent; patients can choose their standard of care, and there is extensive unbundling (e.g. a surgeon gives you a recommended list of supplies, and you have the option to obtain them yourself in any way you wish); non-emergency procedures must be paid for in cash in advance (which tends to result in prices being reasonable); the very poor rely on charities or an extremely basic state-funded backstop.

Such systems are surprisingly efficient and often seem to work better than the lawyer- and lobbyist-designed mess of American healthcare.

Many people arguing against "cancel culture" like to say that it ruins people's lives when they're fired, and it's a statement that is inextricably rooted in privilege. Millions of people are fired or laid off every year - why should one only care when it's because someone said something and got cancelled?
"I've heard a lot of people in my social / online circles comment how they wish they knew whether or not they had antibodies"

What people need to realize is that the important questions are not whether you've got antibodies but:

1 - whether you'll sick when you're exposed to the virus again

2 - how sick you'll get the next time around

No one knows the answers to these questions yet, and we also don't know how antibodies bear on the answers to these questions.

It is possible that even with antibodies you'll still get sick if you're exposed to the virus (as we know is the case for some other diseases), and even if antibodies play some role in how sick you'll get it's possible that (again, as is the case with some diseases) repeated exposure to the virus will cause even greater illness than the first time around.

People shouldn't be assuming that having antibodies means they're immune.. we just don't know enough yet to say whether that's true or not.

Even if it is true, there might be a certain level of antibodies that are required to have a certain level of immunity, and we don't know yet what level of antibodies are necessary, nor the kind of antibodies necessary,

Finally, even if antibodies do grant immunity, we don't know how long that immunity would last, nor if such immunity varies from person to person for some not yet known reason.
I've heard this sentiment expressed. The limits of rationality, reason, and scientific process is a whole topic worth exploring even if just for the philosophic value, but right now, discourse, within the framework of rationality and reason is the best tool society has to solve its problems. There's nothing else. Violence clearly isn't the tool. Nor is emotional reflex. Nor is anecdotal thinking. Nothing else scales and has the capability to tackle the sophistication of society-wide problems.

With isothermal amplification it's hard to control the amplification factor (with conventional thermocycling PCR each cycle (if reagents aren't exhausted) is close to doubling of sensitivity.

This makes LAMP technique purely qualitative... and medical diagnosis of active infection requires detection of specific viral load above some threshold indicative of actual infection (rather than exposure or sample contamination).
Even more basic than Chinese rule of law, CNY is not easy to get ahold of outside of China because of capital controls. If you can’t get ahold of it easily, or move it around easily, it’s not very useful as a reserve currency.
I work in aviation. Maintenance FAA regulation tracking. Aside from all the great points about safety some things to note A lot of people here seem to forget that for the miles and hours in flight versus the costs of AC/upkeep are VERY different from that of a car.

You spend hours and hours in a car you buy. Most small AC have a TTAF of 300 hours or less. And they are YEARS old. Literally nothing is wrong with a carb engine. The planes get fairly good efficiency compared. People also seem to think that planes are being bought at sold in the volumes of cars. Most AC are fairly older. This is why innovations like avionics are up while airframe and engines are low.

I get it that it feels like there's less innovation but I would gather to say there's more. Especially when you get out of the turboprop market. It's essentially the motorcycle industry versus the cars in the road.

It doesn't ban single family homes, but it would ban communities composed exclusively of single family homes. Whether it is called "abolish suburbs" or "promoting livable neighborhoods," once the veil is pierced, it will be interpreted the same. You are right though that "abolish the suburbs" is more rhetorical than fact.

Okay but web apps have no killer app to motivate switching to. Whatever killer app that webapps can come up with, so can native apps.

The two benefits

- webapps don't need to be explicitly downloaded

- webapps don't need to be explicitly updated

Sound good but downloading and updating was never a problem in the eyes of the general consumer. On the other hand

- native apps are faster

And that's a compelling benefit for that even non technical people will prefer native apps for.
Carburetors are mainly susceptible to icing in normal use. Your engine can just start losing power and rapidly quit.

I once had carb icing in Hawaii at 2000' near Wheeler due mostly to humidity, and it was only thorough training that allowed me to figure that out fast enough to apply carb heat and save the plane.

A lot of inexperienced pilots just ride it down into the ground.

Dual fuel injectors prevent the icing problem (usually, unless your fuel actually crystallizes or freezes), but they have other failure modes like dirt or wear. Or forgetting to turn them on.
No, 'moralisation' comes from the emotions of our biology. Disgust, tribalism, groupthink, mob mentality - all the horrors are in our biology, right here, right now, inside everyone, in 2020.

'Godless' non-religious people on the left are extremely 'moral' and burn people at the stake via deplatforming and cancelling.

Science and scientific culture of the last 50/100 years has helped, but even it's been hijacked by our monolithic emotional reality of tribalism and fear. Zooming out, scientific culture is a momentary lifting of a mountain one inch off the ground.

The development of human nature is frozen in time compared to the development of science. Science has caught up to it, and has hit a wall which scientific papers alone cannot move. In fact, the analogy of throwing wads of paper at a wall and expecting it to move. That's the impact it's having.

I fear there is not much we can do about human nature until we can physically change ourselves at the DNA level, to rid or regulate emotions like rage and disgust via CRISPR etc. There's pros and cons of being in the 'World State' or in the 'Savage Reservation'. (Brave New World reference.)

CSS spec doesn't mandate specific font names, those are decided by the font creator or css author. San Francisco is Apple's new (?) font that replaced Helvetica Neue. The typo might be intentional--I had to intentionally use the wrong name for a Windows system font in my @font-face stylesheet recently to ensure the browser wouldn't use the system version (fake-bold italic looked better than bold fake-italic in the headings, and I couldn't find a bold-italic version)

I'm not quite sure why apparently accepted english name for the town is Kharkiv, and author wrongly (understandably) pronounces it as Charkovchanka. Yeah, it's hard - no biggie.

just wanted to let those of you who interested to know how to pronounce it is:
first 3 characters are same as in word 'harvest' and rest almost the way author pronounces it - kovchanka, so

har-kov-chanka

only r has to be softer. It just sounds so much better

For someone who was just starting out and went to a no name college (no insult intended - I did), what signals would a FAANG company have that you are even worth their time interviewing?

I graduated in the mid 90s so I really don’t have a frame of reference. But, hypothetically speaking, if I had graduated in 2012 from the same no name college but spent a lot of time “grinding leetCode” and had the technical altitude to do well in the interview would they have even given me a chance?
Page sizes are easy to lower bound when you're compiling. You know the target system you're compiling for. This most definitely is not in the "compiler heroics" camp.

> If a token is compromised then that will create a problem for that single request because the next token will be different and will be using a new key for encryption.

I don’t follow. What stops a user from replaying any token/request?

Request 1: User sends credentials.

Response 1: Server sends session token encrypted using server’s private key.

Request 2: User sends token from response 1.

Response 2: Server sends a new token, encrypted using server’s private key.

Request 3: User sends token from response 2.

What stops the user from using the token in response 1 multiple times? How does it become invalid?
That's dick, though, not Dick.

I do feel like we shouldn't attach that to a real name that real people have, but instead use actual words like "entitled asshole" that convey the same meaning without lumping in unrelated people who so happen to share the name who have done nothing bad to anyone.

I apologize if it made you feel that and it wasn't comfortable. But part of my consideration in saying that was... this is not politically correct to say (i.e. that it might sound like all conservatives are racist), and I don't know how else to say it, so, I'll say it.

But I do appreciate that you called it out.

I grapple with being racist all the time. The way I climbed up was through a lot of institutions that racist. I grapple with my complicated place in the world, when I talk to my shrink, and not infrequently, because there's a lot of non-PC / uncomfortable things about it all too. I can't get away from both sides of the racism, because of the genes I was born with, so I have to talk about it with someone. If people don't like the whole politically-correct thing, well, this is it too.

Yes, that's what I've read. Any US research scientists still working on SARS-1 after 2003 were told "you're on your own."

Kudos to Canada for being as diligent as Taiwan in attacking COVID-19 - they remember it wiping out Toronto hospital staff in 2003. Check out the Youtube CBC channel for their impressive nation-wide mobilization.

Makes you wonder wtf Chinese virology labs were doing for 20 years with coronavirus if they weren't working on a cure, doesn't it? (There's 40 labs total across China.)
Not necessarily; tech items have huge margins compared to raw materials cost, most of the expense is design and QC. Binned/inferior components marked as the genuine article are worth counterfeiting in a way that other items aren't, besides the other known exceptions (e.g. fashion items)
My student didn't want to be involved with a programming competition because she didn't know:

1) She was an amazingly good programmer relative to the field.

2) Programming competitions can be fun.

It's MY job as her senior to impart that knowledge.

The fact that no other professor imparted that knowledge is a problem--she should have had several professors imparting this knowledge. The fact this was not true shows that such things as "competition teams" are NOT meritocracies.

Oh my, that last bit from Linus there. Been there done that, on a modern system!

So I was making Linux run on a PlayStation3 booting from an exploit, so that we could have full access to the hardware/GPU (not the locked down PS3 Linux support that it came with, and had since been retroactively removed in an update). This is running on top of a built-in hypervisor, on a PowerPC CPU.

I had to debug early bring-up code of the Linux bootloader I was writing from scratch (AsbestOS), and at that point you don't have any real hardware access. There is an internal serial port but it's not accessible to VMs, graphics is way too hard to bring up, USB is also a pain. No usable LEDs too. So what is there? Panic. The hypervisor panic hypercall had an argument with two modes: you could either reboot, or shut down with a beep. So that was my boolean output primitive, which at one point I used to "print" out an address, bit by bit, during debugging the assembler bringup code.

https://github.com/marcan/asbestos/blob/master/stage2/start....

Once I got into C and I could start writing more interesting code, I eventually graduated from panic/reboot to using Ethernet. The Ethernet device was virtualized to some extent. You still had to write DMA descriptors to get packets out, but you didn't have to worry about low-level hardware init. So I stuffed some hand-crafted broadcast UDP packets in there, and the descriptors to blast them out, and called the "start transmit" Ethernet device hypercalls to get printf-over-UDP working. Fun thing is the PS3 has a built-in Ethernet switch with VLANs, so you needed to stuff VLAN tags into the packets if you wanted them to make it out of the Ethernet port. Until the PS3 slim, when they got rid of that switch, and then you no longer needed tags. Fun.

https://github.com/marcan/asbestos/blob/master/stage2/debug....

I used this same UDP-over-LV1-hv-ethernet debugging tool to debug early kernel startup too, after the bootloader hands off, since we had to revamp chunks of the Linux on PS3 early memory startup code (as the memory config while booting in "Game" mode was very different from the formerly officially supported "Other OS" mode) way before graphics was up. This code was eventually upstreamed:

https://github.com/torvalds/linux/blob/master/arch/powerpc/p...

By comparison, when I was doing (unofficial) Linux on PS4 we had the luxury of running on bare metal, and there were testpoints for a serial port on the motherboard, so we could just poke data out of there with some trivial UART code, and use the existing Linux earlycon support for the same after handoff (though the baud rate multiplier was wrong... and also, bizarrely enough, it's an "XScale" ARM variant 8250 port because the PS4's southbridge is a repurposed Marvell ARM SoC with a PCIe bridge to the x86!).
Net harm that law enforcement will do with it is much worse. They can’t be trusted and have to be stopped.
Not even that; the author didn't think through the math right. A SPAC is much more expensive than an IPO:

1. Sponsor takes 20%
2. Warrants give investors the right to buy buy shares cheaply
3. You still get the IPO pop (Nikola and DraftKings both had enormous pops after becoming public)
Wow, hearing that rich people are still allowed to dump lead into the atmosphere above our heads just ruined my morning. What things of non-entertainment value would we loose if we just banned leaded fuel overnight? Are crop dusters burning lead while spraying pesticides over our food crops?
I love Miniflux. I found TT-RSS to be much too cluttered and I enjoyed Miniflux's focus on minimalism & privacy, but that's a personal opinion. It also doesn't require a mobile client: it works just fine in a mobile browser, a big deal when most Android apps for self-hosted RSS readers are either ugly or unmaintained.

Setting up Miniflux was problematic because documentation around its pSQL & environmental variables aren't too well-documented or universal in implementation.

However, I've noticed a lot of people really don't like Miniflux because it is very minimal and doesn't try to do everything.
