The company I contracted for marketed them for LED production (I don't know the details, but making tiny gaps on the right places in the surface could somehow make the LEDs more efficient) and for the upper layers of chips, where way less precision is needed.

We got to a .8 micrometer error margin, which is "an enormous valley" by ASML standards but still fine for the top ~5 layers of normal semicon designs, where there's typically way fewer lanes, placed more widely apart. Again, I don't know much about chip design so I probably got all the details wrong.

Basically, yes there's a market. It's not at all as big as ASML's but it doesn't need to be. There's also a market of refurbishing old ASML/Canon/Nikon machines and repurposing for different parts of the production process (either chips or other semicon stuff like LEDs), which is what a new litho startup would compete with I think.

Note that all my knowledge about this is 5 years outdated, I now run a chat api startup :-)

Until we realize that tribalism is human nature, it won't change.

Racism is universal amongst humans. We are tribal primates, after all. We need to admit the biases exist and address them head-on.

It stands to reason that having a bias against out groups once increased an individuals chance of survival. Now it is actively harming society. If we can't rise above our primitive impulses, we are doomed.

Police often don't want to live in the community they patrol because they don't want to be recognized with their family while off duty by gang members they interact with, making their families targets.

I have close family who had to move to a different city because of direct specific threats to their family made by gangsters.

Organized crime changes the dynamics completely.
I'm assuming that given a starting point A and a number of operations n, there's a much faster way of computing the end point than just iterating n times?

Otherwise, determining n given A and an end point would just be a matter of iterating from A until you hit the end point and counting, right?

Also, how do you actually use the keys to encrypt/decrypt?
Writing code in a commercial IT shop in the late seventies, the manager though he was progressive since he guaranteed that we could get as many as one compilation per day. We'd submit punched cards and get back the card deck and a compile listing when it was done.

Hardware was less reliable, occasionally coming up with the wrong results. One time the result was wrong because the printer had printed the wrong digit! I'd spent hours desk checking the code only to find the code was right. So I ran it again.

It was much more normal for managers to really not know what a computer really is. This included programming and IT managers. One very accomplished boss asked me, in a meeting, how long it took to write a program. What kind of program? I asked. Oh, a general program. That put me in a no-win situation. If I said a year, he'd pop a cork and get all red-faced. If I said two weeks, he'd hold me to it no matter what the program was supposed to do.

Being 63, I don't get to say this very often: I am one of the youngest people in this conversation.

Delighted to read these stories about even-older-than-me old-timers. Even though I am a relative spring chicken, I'll list my old-timey computing experiences:

- Started programming on programmable Wang and Monroe calculators.

- PDP-8m in high school. 12k 12-bit words for four terminals running Basic. By special arrangement, I could take over the whole thing and use FORTRAN.

- IBM-370 in college, and I spent lots of hours on an IBM 029 keypunch. (That's where I developed my love of loud, clicky keyboards.)

- First job with Datasaab (yes, a computer division of Saab), and I programmed in their weird DIL-16 language.

- PDP-11 in grad school.

- Various VAXen in my early working life. Picked up Emacs in 1985 and now it's in my fingertips.

- A buddy and I wrote a book intended to support people who needed to work with a large variety of computing environments, (a real problem my buddy encountered). It was instantly obsolete, as it was published as minis were dying and PCs were becoming dominant. (https://www.amazon.ae/Computer-Professionals-Quick-Reference...)

- Many years in startups, mostly in Unix/Linux environments.

Retired now, but still enjoying programming. Having a blast with my current project: https://github.com/geophile/marcel.

The Wikipedia page I linked to lists a 2018 IEEE paper; her company's website still has her name on it.
Many organizers of protests in Furguson, peaceful or otherwise, have since been found murdered in ways that suggest they were literally hunted down and killed for their involvement. Multiple have been found shot through the head in burned out cars to destroy all evidence. If they broke the law it still does not merit being executed in the street. (https://www.nbcnews.com/news/us-news/puzzling-number-men-tie...)

In a situation where police feel justified to kill extra-judicially over a possibly fake 20 dollar bill, what hope do we have that protesters won't be targeted in unfair ways? Or worse, that organizers won't be hunted down like animals and murdered like in Furguson? It would be unethical to not do everything in your power to protect those in this position.

secondly how do you plan to identify violent vs non-violent protesters from a static image? How would you find their identity afterwards? There is overwhelming evidence to suggest these methods are at best ineffective and at worst racist, and in either case will lead to innocent people being charged.

It's only testable in the data if these decisions are being made based on factors that are adequately represented in your statistics (no unobserved confounding). Maybe there's patient A, a smoker who says they're a non-smoker but seems like a liar to the doctor, and an otherwise identical patient B who is actually a non-smoker. Patient A is probably higher risk, so there's a difference between doing A during conference week then B later, versus B during conference week than A later. Even supposing that the doctor wrote that they think A might be lying and actually maybe a smoker, it's going to be hard to control for those notes in a t-test. It's a shitty example, but hopefully demonstrates the idea. It's always super hard to make the argument that there's no unobserved confounding.
I think the median of the results works great in any case (but, you are the expert here). If we find the result median in each of the two inputs, say 'a' and 'b' we have four merges (two forward, two reverse):

[0, ..) w (0, ..)
(.., a) w (.., b)
[a, ..) w [b, ..)
(.., n) w (.., n)

each of which should produce n/4 elements and then meet.

If the array is already sorted then great; that split will just "merge":

[0, ..) w nothing
(.., n/2) w nothing
nothing w [n/2, ..)
nothing w (.., n)

which should go very fast. Anyhow, possible I'm missing something!
Considering how long the ISS has been up there, it could be POTS or something similarly-analog. Dragon→ISS was clear, but ISS→Dragon was not, making me think that maybe there's some wire or connector in the latter direction that's shoddy (and that'd be more common for analog/POTS than digital/VOIP, where such garbling would be bidirectional and/or nothing would be heard on either end).

Then again, I ain't exactly a space telecom engineer, so what do I know? ;)

Looking at the ACE2 alignment from the article, it looks like there are 55 spots where the sequences have different proteins. Of those 55 spots, 7 of them are identical between the bat and sars2. On the other hand, I count 20 matches between sars and sars2.

Using a uniform distribution over the 20 proteins, and saying the probability of two proteins matching is 1/20, then the binomial probability of getting 7 or more matches out of 55 is 0.02, whereas the probability of getting 20 or more matches is less than 0.000001.

I can see 0.02 being achieved by chance, but 0.000001 seems pretty unlikely to happen by accident. So, there is some sort of non accidental relationship between sars and sars2. Maybe 1) sars2 is descended from sars, or maybe 2) it is lab engineered.

If the bat coronavirus is likely the more proximate ancestor to sars2 than sars, then #1 seems unlikely, which makes #2 the more plausible hypothesis.

Also, to return to your argument about restricting our 'lab origin' hypothesis to known viruses, it seems that if WIV found a very effective bat coronavirus, and intend to create a bioweapon from it, this is exactly the situation when they would not share the sequence. I do not understand why you think people creating a bioweapon would want to share their materials with the world.

Edited - wrong number of seats for the next mission.

NASA asked SpaceX to change the configuration of the capsule to only support 4 astronauts for two reasons. The first is that they wanted a more mellow Load profile on the passengers in the case of a high-altitude (almost orbit) abort, so they wanted the seats in a different position. The first design had the seats fixed, and the screen pivoting down above them. This design has the seats pivoting, and the screen fixed. It also drops the maximum crew from 7 to 4. I’m not sure if SpaceX will use the larger configuration for their own private configurations.

The other reason is that seven is a lot, and NASA doesn’t plan on sending that many up on a single mission.

Seats 1 and four are empty on this mission. For future missions that only have three they will remove the extra seat. That said, the capsule seems amazingly spacious, for being a capsule.

As far as costing, the contract was written similar to how NASA pays the Russians (though that number is upwards of 87 million per seat right now). SpaceX itself owns the rockets and the spacecraft - not NASA. Think of it as a airline seat.

Finally, the vast majority of cost at this point are not the hardware - but rather the cost of complying with NASA’s testing. Everyone was assuming that NASA would do what they did with commercial cargo, and simply expect the cargo to show up with a minimal number of design reviews. With commercial crew, NASA took a much more proactive approach which led to a complete redesign of the capsule (SpaceX’s original plan was simply to reuse cargo), plus many many many design reviews.

Finally SpaceX has full pricing control right now. SpaceX is running some pretty massive margins (from what I have heard) on everything - but they are flushing all of that money into the goal of getting starship and spaceship and their insane next generation engine up, as well as starlink. They have deliberately only lowered their costs below their competitors, soaking margin for a while.
Ask HN: What is a realistic timeline for affordable space tourism?
With all of the excitement over the SpaceX launch yesterday, I have been wondering, what is a realistic timeline for affordable space tourism? By affordable, I mean an extravagant but potentially realizable expense for a middle-class consumer. Perhaps around the cost of a luxury car.
Deconvolution is any attempt to recover data that has been passed through some known transformation. It can "create new data" because it is effectively mathematically-educated guesswork.

In the case of upscaling an image, deconvolution involves looking for images which, when scaled down, resemble the original image being upscaled. That kind of pre-image approach can be applied to blur as well (if the blur process is deterministic).
Shadows are blurry unless the source is a point. The gradient is the part of the shadow where the source is partially occluded.

I used a Lamy of some kind for over a decade. I’m not sure what model it is as they don’t seem to make it anymore but it looked like a brushed steel version of the cp1 but with a thinner clip rather than one like on the 2000. It’s much thinner than most fountain pens and I think that’s often helpful to people used to writing with thinner pens. Sadly it remains with my 2000 in my desk drawer in the office.

> was mainly talking about how development on Linux Kernel can be tedious, the adoption of the drivers is usually limited

You literally provided an example that does not work in your favor to prove your point.

> Realtek is one huge manufacturer of network chips, but their drivers on linux are still crap?

That's not the case for years, rehashing the same arguments you had a decade ago, or simply being this clueless does not help your case.

> the only thing I hear about Intel/Nvidia from Linux people is complaints about how shitty they are, and why they dont open up their stuff.

You don't really know what you're talking about and it shows. Intel is fine, they have dedicated developers supporting Linux with open-source code, the problem is an Intel+NVIDIA laptop combo and this is due to NVIDIA, not Intel.

NVIDIA support is crap, because NVIDIA wants it to be crap, since they sell enough GeForce GPUs to gamers not to care, nothing Linux can really do about that, it seems that Intel and AMD have no problem shipping a kernel driver. It's a culture thing, more than anything.

And yes, we want the driver to be open, caring about free software is one of the major reasons to go with Linux.

> One key thing might be that debugging of kernel things is not easy on Linux, as listed on the Original Post url?

Much, much easier than on Windows, you even get DTrace, get to inspect the code etc. That's not the issue. Anyone who wants to provide a driver has no problem providing one.

ARM is its own beast, but as I said earlier, this is mostly due to there not being a standard way to i.e. probe hardware like there is on x86 and that's ARM, not Linux at fault here.

Does Linux have problems, sure. But as someone who had family members with Windows 10 call me that they lost their files after an update and the internet is full about the latest macOS being the new Vista, I wouldn't be too sure the competition fares better.

> Yes, i said it. 99% of the people don't care if theres telemetry reported if it can improve the product.

Maybe they don't care, but I'd argue they seldom even know about it or understand the implications.

> As a developer myself, I would _love_ to have _real world issues_ reported to me, automatically.

Part of the free software movement is about equality between users and developers because developers have unquestionably more power. This is more of an ideological thing than anything. Nobody's saying telemetry isn't useful, just that one should be up-front, opt-in, full disclosure about it.

A large part of us care about that, about privacy and the future of unrestricted, general-purpose computing.

I am sure many don't and for them Windows and macOS are there. If Linux doesn't work well for you, that's fine, what I find annoying is pretending that Windows/macOS are somehow way less annoying to use, when every time I use them, I come across crappy behavior.

> Lower cost to orbit, sure. Increased economic activity in orbit? Where does that part come from?

Lower cost to orbit translates pretty directly to increased economic activity in orbit, since said economic activity is less expensive to do (and therefore more accessible to more people).

But agreed. This ain't a huge achievement... yet. It's essential groundwork for that achievement, though.

> I'm assuming that given a starting point A and a number of operations n, there's a much faster way of computing the end point than just iterating n times?

Yes, this is in fact the basis of the cryptographic security. There's a way to iterate the generator whatever number of times, fast. This is called multiplication, just like there's a way to multiply arithmetic numbers in school without adding over and over.

The thing is it isn't quite so easy given the starting point and the result what you multiplied by.

Yeah, I was so excited to get my hands on UCSD Pascal because there wasn't a C compiler for Atari 8-bit. It was multi-diskette and sooo slow I never really ended up using it.

The "Action!" programming language cartridge was the best thing ever. Somewhere between C and machine language. Being in ROM it booted instantly and contained a built-in editor, compiler, runtime, and monitor. It compiled about as fast as Go does now on modern hardware.

It wasn't until I got an Atari ST (Megamax was good) or PCs that C I got to use C compilers at home.
