> DNA has a half life of ~500 years

DNA is not a radioactive material. It decays, but there's no absolute law like the radioactive decay, where the half life is the same for every microgram of the same substance everywhere in the world. The average half-life may be 500 years, but there can be situations where the DNA is exceptionally well preserved due to local circumstances. As a simple analogy: the average half life of a human settlement is, let's say 50 years. That means we should see absolutely no traces of human settlements older than 2000 years (40 half-lives). That is far from true.
> If I understand correctly, that would actually be "implementation-defined", not "undefined".

That is an extremely common myth. From the point of view of the Standard, the difference between Implementation Defined behavior and Undefined Behavior is that implementations are supposed to document some kind of behavioral guarantee with regard to the former, even in cases where it would be impractical for a particular implementation to guarantee anything at all, and nothing that implementation could guarantee in those cases would be useful.

The published Rationale makes explicit an intention that Undefined Behavior, among other things, "identifies areas of conforming language extension".

> There are size-specific integer types specified in the C99 standard (e.g. `uint32_t`). I use those, except in the most trivial cases (e.g. `int main()`), and limit myself to those size-specific integer types that are "guaranteed" by the standard.

A major problem with the fixed-sized types is that their semantics are required to vary among implementations. For example, given

int test(uint16_t a, uint16_t b, uint16_t c) { return a-b > c }

some implementations would be required to process test(1,2,3); so as to return 1, and some would be required to process it so as to return 0.

Further, if one has a piece of code which is written for a machine with particular integer types, and a compiler which targets a newer architecture but can be configured to support the old set of types, all one would need to do to port the code to the new platform would be to add a directive specifying the required integer types, with no need to rework the code to use the "fixed-sized" types whose semantics vary among implementations anyway.
Why hide the password box, then, unless you think that users learning to type and have magically it go somewhere invisible is a good UI design…

(Interesting aside: I complained to someone on the Mac Safari team that it was difficult to search open tabs, and he told me that apparently this feature already exists! You go into the tab overview, and…just start typing. A little search bar will pop into appearance in the top right corner. Why it couldn't just be there and have keyboard focus from the start, I have no idea…)
Casino Review
If you have a giant full-screen window with tabs, inactive controls are never visible, so there is no reason to make an inactive appearance.
I've used AirBnBs a lot and there has been a range of cleanliness. I've never had one that wasn't clean enough to stay in though. The large majority of my AirBnB/VRBO/etc... experience has been in Europe so that may contribute to my experience.
He describes stories as 'relics'. Here's a direct quote from the book: “Stories are relics, part of an undiscovered pre-existing world. The writer’s job is to use the tools in his or her toolbox to get as much of each one out of the ground intact as possible.”

The book is pretty good, well worth the read if you're only slightly interested in the topic!
It could have already passed through all of those communities basically unnoticed, and/or confused with other ILIs. There's no way to rule out that possibility, and when you consider how rare cardiovascular diseases (the most common comorbidity) are in those communities, you have to conclude that it's not vanishingly unlikely: https://minorityhealth.hhs.gov/omh/browse.aspx?lvl=4&lvlid=4...

Obviously mitigation efforts still play some part in limiting the spread, but I would not bet that all of those communities were able to suppress such a contagious disease before a big chunk of the population was exposed to it.
That's highly inconvenient. The best solution I've found is optimus-manager or prime-switcher.

What does Covid-19 do to your Brain
Right, but even a small amount of water (and presumably, ice) is amazing at absorbing radiation. Wouldn't something buried in a few meters of ice or more be effectively insulated from radiation?
So is the answer:

I hold a pessimistic viewpoint because it's a lot more insightful to look at losses than it is gains.

With so much brick-and-mortar retail shut-down, retail has to happen somewhere, so it's going to happen online. Increases in product sales online could result in net declines for the product group when you factor in the loss of B&M sales.

I think the logical result here is pretty well-represented in how some public companies in this space's stocks prices are playing out. Distribution companies are likely to prosper because their competition has decreased substantially:

* Amazon is at an all-time high
* Overstock has recovered their dip
* Wayfair is recovering their dip
* Chewy is at an all-time high

None of this means the manufacturers who these distributors are selling are doing well, though.

On the flip side, the product categories that are down substantially online are likely facing devastating loses. They already aren't selling in retail so if ecomm is it and they're down there, it's really bad.

Outside of distributors, I think the D2C ecomm space is a huge mixed bag but likely net negative for a few reasons:

1. A lot of DTC companies play in the product categories that are seeing lower online sales

2. Most DTC companies are positioned as being accessible, but still premium. There are cheaper alternatives people may be more inclined to go with, given the economic uncertainty.

Given that, layoffs at Away, Everlane, Third Love, Stitch Fix, Casper, etc. make sense, even if online sales as a whole are up. Some of them may even need to start paying attention to unit economics now! I'd guess a lot are scaling back advertising and trying to focus on lower-cost acquisition channels to keep a tighter grip on cash flow.
Would the meaning have shifted in the last hundred years?
Worse, this creates a bad habit. What if the UI changes and now it's the username that pops up first, not a password box?

So it's a hard-to-discover feature, and a misfeature unless you elect to keep this behavior forever.

I was going to make a comment about how this might be a mobile thing, where focus is less of an issue because everything is fullscreen, but now iPad does multiple windows and has the same focus problem…
Joel Spolsky has an old post somewhere where he says the reason the Palm Pilot failed but the iPhone succeeded at making mobile devices "a thing" is that desktop and mobile are two different things; the Palm tried to do a desktop interface on mobile.

I'm ok with three-dot menus on mobile, especially for features like "settings" that I don't use all the time - Whatsapp's dots menu works for me.

Using a dots/hamburger menu on desktop is lazy, I'd agree with you there; using it on desktop for things that people do use a lot like the editing menu in a painting program is atrocious.
Washington State has a more measured approach, the Governor has told people they can still go outside for walks, just stay apart.

A lot of hiking trails did get shut down after people crowded them, parking lots were overflowing when people were supposed to be social distancing, so that didn't go well. But the majority of city parks and trails are still open, only the children's playgrounds are closed.
No, He is talking about the laptop not getting enough power while plugged in.

If there was any added weight it would be with the charger, not the laptop so... Incredibly unlikely.

It's way more likely that Apple just didn't design the connector to be able to deliver that amount of power. So they'd have to add a second one or switch connectors/design a new one.

Both would be suboptimal as well.
Against who? An email and an IBAN number? For our B2C with relatively small charges it definitely wasn’t worth it. Even CC chargebacks we don’t bother to dispute because the process is painful and virtually impossible to win (banks side with their own customers typically)
I’m reminded of packaging I’ve seen that claims to be environmentally friendly because it can be crushed up to be smaller. Because smaller takes less space which presumably takes less landfill.

Having said that, “recycling into a cat house” is probably just as valid as thinking you’re recycling but it just gets sent to China and presumably dumped.
BTH News 17April2020 – Between the Hacks
It's not "someone else's stuff," it's the city's. The non-profit "manages" the park, but they don't own it.

An anology might be that you let a friend watch over a cabin in the woods in exchange for letting you use it for parties and stuff. Now you don't people to use the cabin for a while (perhaps wildfire season or bears spotted very close by), people still keep using the cabin, so you change the locks.

Still arguably a dick move depending on the dynamic of the park and skaters and what have you, but well within the city's rights. The only "damage" was to their own property.
This may be a true statement when applied to public health professionals, but is quite likely dangerous to public welfare when in the hands of disinformation campaigns and propaganda.

Virus Claims at Least 6,900 Lives in U.S. Nursing Homes
More asymptomatic and mild cases would lower the death rate to something more akin to the flu. It would also mean that we'll achieve herd immunity quicker than previously assumed.

Lots of the fear was based on assumptions that this would be as deadly as SARS or MERS but at this rate we're looking at overall deaths that is slightly higher than the flu but lower than things like cancer or heart disease.

My main method of exercise (surfing) was cut off due to rules & fines. Honestly after 2 months of this I feel like I am withering away.

I feel like if I get sick, the disease is going to take me out.

And yeah, it's absolutely ridiculous. Nobody who surfs ever wants any other person within 10ft of them. That's highly discouraged under even normal circumstances.
The problem isn't anti-gouging laws, it's that medical customers aren't willing to commit to long-term contracts to justify the investment to increase production.

> ...during an outbreak like this, everybody wants to be [an American mask/respirator maker's] customer. But as soon as an outbreak subsides, his customers dump him and run back to China. The reason? His masks may cost a dime each, but a made-in-China mask might go for two cents.

> “Last time he geared up and went three shifts a day working his tail off,” the mayor recalled. “As soon as the issue died, he didn’t have any sales. He had to pay unemployment for all these people, and he had to gear down.”

Also, why would you think anti-gouging laws would be the problem? The only thing raising prices would do is send PPE towards people with money who may or may not have actual need. No one sensible is going to ramp up extra capacity or create stockpiles of perishable goods with the idea that they'd be able to gouge during infrequent, unpredictable crises. The only people that price gouging helps are the parasitic middlemen who make a profit engaging in it, and the fools with money to burn who can't demonstrate priority need.
You can do a lot with an apartment balcony, too. Even though it's space-limited, the warmth of the building will help.

Though not inappropriate for the climate, when I lived in Ohio, I grew tomatoes, corn, and pumpkins in containers on my balcony. The pumpkin vines grew into the adjacent tree, and in the fall, there were small orange pumpkins hanging from the tree limbs, like fruit.

In Texas, I grew all kinds of citrus trees in containers on my balcony, as well as watermelons. The trick with watermelons is to hang the fruit inside panty hose so they don't get damaged. It made them wonderfully round.

Again, not a climatic challenge, since they say, "You can plant a broomstick and grow brooms in Houston."

I write a lot of compute kernels in CUDA, and my litmus test is prefix sum, for two reasons.

First, you can implement it in pure CUDA C++, and max out the memory bandwidth of any nvidia or AMD GPU. The CUB library provides a state of the art implementation (using decoupled-lookback) that one can compare against new programming languages.

Second, it is one of the most basic parallel algorithm building blocks. Many parallel algorithms use it, and many parallel algorithms are "prefix-sum-like". If I am not able to write prefix sum from scratch efficiently in your programming language / library, I can't use it.

Every time someone shows a new programming language for compute, the examples provided are super basic (e.g. `map(...).fold(...)`), but I have yet to see a new programming language that can be used to implement the 2-3 most fundamental parallel algorithms from any parallel algorithms graduate course. For example, Futhark provides a prefix sum intrinsic, that just calls CUB - if you want to implement a prefix-sum-like algorithm, you are out of luck. In WGPU, it appears that prefix-sum will be an intrinsic of WHSL, which sounds like you would be out-of-luck too.

You mentioned WGPU and Vulkan. Do you know how to implement prefix-sum from scratch on these? If so, do you know how the performance compare against CUB?
Aww, he had to go after the Gnome stuff :/

Many a time I have spent over a minute decoding a Gnome GUI for incredibly simple applications. Is that a clickable icon? Why is that icon/menu option greyed out? Toggles, icons, buttons, toolbars thrown together with a rare tooltip. I fully agree they border on parodical.

And yet I still use the gnome tools frequently, because they are useful. So in a way I do feel bad for complaining because I am certainly not stepping up to the plate to improve these tools.
> If you're in the sahara desert you basically have all materials you need to create an iPhone. Not in a million billion years will there ever come an iPhone into existence by mere accident of natural forces in that desert, would there?

The evidence says that actually did happen. Abiogenesis and the evolution of human beings were just part of the process of producing an iPhone through a "mere accident" of natural forces over the course of the last 4.5 billion years or so. Producing an iPhone was never the goal, of course–natural processes don't have goals. But it was one of the consequences.

If God can exist without being created, so can what you refer to as "His creation". This idea that the visible universe requires a Creator, who in turn does not require a Creator, is arbitrary and capricious.

I wonder if gyms will ever come back from this. Gold's announced yesterday they are permanently closing 30+ locations. Even when people go back out, gyms were never the cleanest places to start with. Some places will require masks for the near future, so how does that work at a gym? Now that I'm been forced to finish my home gym, I'll likely cancel my membership once things open again.
There was a paper not long ago saying that the DNA half life is about 500k years or so and that most of the DNA would be degraded.

The issue I had with this is why can't we reassemble chunks of DNA like we can with a puzzle.

I'm certain specialized algorithms exist within DNA analysis for this reason. This isn't my field and there are already algorithms that exist on the top of my head that could solve this issue.

The main issue is that you'd have to find a LOT of DNA to build one complete strand and you wouldn't have one strand from one specific animal.

... but you'd have a rough picture.

White bleaches out. Bright spaces are more inviting and photograph better. And once something white is clean, you can see it is clean, so you can "feel" how clean it is in a photo. And everything is from Ikea anyway so just throw it out if it's really done in. You've likely made enough to exchange some covers every six months.
Also worth considering that this program, by design, under-cut bank's own business loan offerings. That's why we see a lot of small "customer focused" banks offer it, and a lot of the big ones drag their feet long enough for the program to run out of money.

They don't /want/ companies to get a loan this way, they want companies to get a bank loan. No doubt they'll be spamming all failed applicants with offerings of "discount" bank loans soon.

Venezuela's problems come from international banking controls combined with hyperinflation and mandates to not increase prices. When you have a currency losing its value every week and the government mandating 10 cent gas with no way to transact with the outside world and escape your currency, things are going to get very distorted.

Venezuela has much bigger problems than price caps, it is not indicative of systemic ramifications either way here.
I think we're in a strange bubble. Rapid iteration was a potential source of improvements (never going wrong since you can always adjust next week vs potential big fail every N years) and that it would yield better understanding of users by throwing every possible solutions at them.

Socialism -- Worker ownership of the means of production.

Socialism is not "when the government is big" or "when the government does things".

A big federal government is not socialism. Norway is not socialism. Heath care is not socialism. Unions are not socialism. China is not socialism (charitably it's a state-captialist government with the goal of achieving socialism, realistically it's an authoritarian state-capitalist government).

Maybe you use a big or authoritarian federal government to try to achieve socialism, but a big federal government is not necessary or sufficient for socialism.
