There is also a matter of accuracy. I believe stealth planes are often “detectable” at longer frequencies, which however do not give precise enough information to fire a missile at them. So you’ll know they are coming but can’t shoot them down. I would imagine radio signal triangulation falls into a similar category.

Thanks. This looks cool.

A question: when trying to play SNES games, it requires an .sfc file. This is for japanese games for the SNES.

Is is possible to make it run .smc files ? those are american versions, much easier to find, with english text by default.
We only know that you are likely to be immune for six month. Whether you will have life time immunity is anyone’s guess.
I believe the poster was referring to bad actors who have tried to buy up all the local supply so they can resell it at higher prices, not people just stocking up a bit on toiletries for their personal use. Yes, the latter can also cause a shortage but that’s not the cause of the ethical dilemma here nor is it the motivation for price gouging laws.
I'm not doing the testing. Simply creating a place people can go to find out where to get tested.

Can't know if you should be quarantined if you don't get tested.

Why can't all the background checks and inspections be part of the process towards tokenizing the house? If everything is verifiable and transparent on the blockchain it can surely be used for this process.

The key with this is it's not unsecured. It's secured by something.

Many people fail to understand that there's a huge difference between detecting the presence of an aircraft and actually targeting it. Anti-aircraft weapons must be precisely targeted to have any chance of hitting. So a passive radar can be useful in limited circumstances for cueing other sensors but it can't accomplish much by itself.
Flattening the Curve Math
Sometimes there are two (or more) threads for what is essentially the same story. When this happens, Dan (or one of the other moderators) frequently chooses one thread to keep, and copies the comments from the thread(s) to be deleted into the thread to be kept. If commenters have already posted the same comment to both threads, this requires more manual cleanup by the moderators. There's a lot of moderation that happens behind the scenes here to keep the site as usable as it is.
One would have to assume it’s overestimated. Authorities are going to be careful not to underestimate.
If your dependencies use CMake or not doesn't really matter, you still end up writing some FindX.cmake file.

(Which is a whole other thing with this "modern CMake" by the way: only half of them that come with CMake are "upgraded" to modern and if you don't want to require the absolute latest version, you end up having to check what the FindX script did or redefine stuff manually)

And not all slightly older people meet the expectations of tech use for that slightly older generation. I think it's not uncommon for HN, but I have a minimal social media presence, and am rarely an early adopter-- more like a stage-2 adopter once something is proven, and very much not on board with social media adding anything positive to my life. So-called digital natives are, I think, becoming increasingly skeptical as well, in a grass-roots phase of limiting contact to closer, well-known friends/acquaintances. Not yet a majority, no, but the beginning of what has the potential to be a trend.

If nothing is done about the above, seems like there's little chance that parking in bike lanes or on sidewalks in front of lunch/snack spots is going to be addressed.
If you do things physically, you can do it easily.

For example you could have a hat with pieces of paper in it each with a number. The numbers sum to 0 (some are positive, some are negative). Each person draws a piece of paper, adds his or her weight to it, then says that number. The numbers that each person says are summed and that's the total sum.
There is plenty of market hungry for devices like this. Companies were buying Hololenses in fairly large quantities (tens up to hundreds!) for their internal use, despite it being essentially a lab product and not very suitable for day-to-day industrial use. Oh and US Army signed a contract for up to 100 000 (!!!) of these (see: https://www.theverge.com/2018/11/28/18116939/microsoft-army-... )

The same Hololens 2 - except there Microsoft isn't able to deliver these due to manufacturing issues.

That something isn't selling millions of pieces like an iPhone doesn't mean that there isn't a market for it.

Magic Leap's problems were mostly of their own making - their gizmo wasn't significantly better than Hololens, in many aspects it was actually worse. For ex. the "goggles" form factor limiting spatial awareness - big deal e.g. in factories where a maintenance tech wearing it could get hurt or killed by a moving piece of machinery that they couldn't see.

They have also focused mostly on hype rather then things that actually matter to businesses (given the price and form factor trying to market it to public was a non-starter - Microsoft didn't even attempt that). And, finally - you can't actually buy the gizmo, even if you wanted to - they aren't selling it anywhere except in the US! Unlike Microsoft, which has no such issues.

I do wonder if this decision doesn't have a Brexit component, the transition period will be over the end of this year, so I guess that is when the real bad stuff from Brexit will start becoming clear, if you mess up your economy the year before by lockdowns then what happens when things go really downhill?

If you don't lockdown, and other countries do, can you somehow benefit? I would say no that doesn't make sense but I somehow have the feeling that the people who currently lead the UK do not share my understanding of what is reasonable in any way whatsoever so maybe they would have a Baldrick level cunning plan in mind?
A: No price controls, scalpers buy everything and resell at 1000%. Only people who can pay that much get it until the manufacturer ends up at 10x output, which can take a long time.

B: Price controls, at least some distrubution of everyone gets some, less incentive to hoard, stores still allowed to raise prices a little (just not a predatory amount detached from real costs) when the manufacturer does when ramping up production.

The shelves are empty in either case, the difference being a nonzero amount going to poorer people in B.
Doesn't seem so clear. During a recession, you might have less money for investing green technologies. No one will be able to afford an electric car. You might get more family time but the stress of the main earner being unemployed will mean it's not high quality.
That is a straight up nonstarter.

It would be triangulation if the system was measuring the arrival angles of the incoming signals. If the system relying solely on arrival time differences, it's likely doing something based on trilateration.

Fashion aggregator that finds clothes that will fit you
58% percent of returns when buying clothes online are because they are the wrong fit so if you are looking for clothes online, you are probably looking at brands that weren't made for you.

I'm the co-founder of https://www.shopyourfit.com/ , the first fashion aggregator that shows you clothes based on your body shape (both new and used).

How does it work: You scan yourself from your phone and, based on your body-shape and measurements; we only show you clothes that will. fit you (and we tell you were to buy them)

Some SYF features:
- Find clothes that are for your body shape and where to buy them
- Discovery high-quality, low-price brands that you've never heard of (and are for your body).
- Sell used clothes you have at home at 0% commission.
- Buy used clothes (you will only see clothes from sellers that have a similar body to yours to ensure clothes fit).

SYF allows you to find clothes that will fit you in minutes (when you are probably taking hours browsing right now).

We have launched it recently and I'd love to hear your feedback. Try it (preferably on mobile) at https://www.shopyourfit.com/
I blame Apple for people not knowing about paths. An acquaintance always used windows and then switched to Mac. She usually had her stuff neatly organized, but a year later, there was zero organization any more, she was just using the finder. If search is good enough, you don't need organization. Folders and files are hierarchical categorization, you don't need that if you can access everything by search.
From having a dig around earlier today, https://coronavirustechhandbook.com/remote seemed like a good collection of resources and guidelines.

It seems like a plain anonymization problem, much like a voting with a secret ballot. If I encountered this problem in real life, I would just use slips of paper and a box with a slit in it. Possible strengthening techniques would involve removing the handwriting, for instance using multiple choice 0-9 for each digit.
B-2 is old but the stealth shaping is still much better than F-35 and there is much more internal structure inside the wings that absorb radar energy. The RAM paints used in B-2 are probably up to date with current technology as well.

B-2 is also inherently more stealthy to to Rayleigh scattering than F-35 is due to the size.

Stealth is not magic. Shaping is 90% of the stealth, rest is the materials and details.

Vera-type radars may be be able to detect stealth aircraft with low angular resolution but they can't be used for targeting.

I'm curious about the following two aspects: 1) were changes in DigitalOcean's executive management (in particular, their CEO replacement) prompted by founders' desire to change their focus / reduce their workload / whatever or pushed by some of DO's investors; 2) why DigitalOcean is an LLC (to the best of my knowledge, an absolute majority of VCs insist on their potential portfolio companies being a C Corporation (mostly, a Delaware C-Corp). Thoughts?
Thank you!

I’ve mused about setting up a service like this to tie up loose ends that are not addressed in wills. I’ll take a close look at your service.
On the other hand, a generalist is in the best position to understand where it is most beneficial to go deep. Even just the exercise of thinking through your domain, and trying to identify where you should best allocate your resources is useful.

I'm in a profession now where full 100% of the founders of successful start-ups in this domain started off in a different industry. It's kind of astonishing that none of the experts in the field have been able to leverage their knowledge to start a successful company, they just act as consultants.

SFC and SMC files are usually identical. It’s just a different choice in file extension.

“SMC” comes from Super MagiCom, a floppy-based cart copying device for backup/piracy. The original .smc files produced by the device contained a 512 byte header. Since it’s pretty easy to detect and ignore most emulators do. If not, it’s easily removed.

Because .smc is in reference to effectively a piracy device, the new preferred file extension is .sfc and has been for a while now.

(In case it is not obvious, the file format is nominally just a raw dump of the ROM on the cartridge with no added headers.)

(Note 2: if you are looking for a way to run homebrew/patches/etc on a real SNES/SFC nowadays, sd2snes is probably the absolute best option.)
From the chemistry we’re aware of on earth, sure. But I imagine the energies required for our water cycle based life would look astronomical compared to the energies available in a place like Pluto.

This sounds like a cool problem space for computational chemistry.
We already get infected by corona viruses all the time. We usually call them colds.

If you weren't worried in 2019 about letting the common cold circulate in case it may get even worse, you probably don't need to worry too much about this one either.

Viruses tend to have an incentive to not kill too many of their hosts -- because it limits how they can spread.
More to the point, detecting a stealth aircraft is very different from shooting at a stealth aircraft.

This radar would likely not have the location accuracy of where exactly the B-2 was to accurately engage it with a missile. Your accuracy would be limited by the rate of RF pings the B-2 is putting off, and then the margin-of-error of these RF waves and receiver.

This is one difference between the B-2 and stealth fighters like the F-22 & F-35: The latter are not necessarily designed to be invisible, only impossible to reliably hit. Their shapes and radar-absorbent paint deflect, diffuse, or absorb the high-frequency bands used in the terminal guidance of missiles. So they are hard to target. But they can be picked up at range by long-distance, long-wavelength VHF and UHF radars. These frequencies, used in early-warning radars, have too low-optical resolution* however to be any good at aiming guns or missiles. The B-2's "flying wing" shape is able to not-interfere with these wavelengths though, and hence hides from them. In that sense, this is somewhat interesting, if neutered for the reasons you mention.

*You can only localize the detection to a few sq hundred meters, even kms.
Could use a similar technique remotely using a random number generator. Provided there are enough passengers the sum would approximately equal the true total weight.

There might be behavioural issues here though - perhaps people would keep generating a random number until they are provided one that makes their weight look 'better' (and 'better' probably means 'smaller' for most people).

Edit: comicjk made a great point about large numbers. Perhaps using large random numbers (eg a normal distribution with a mean of 4550 and a std deviation of 20-30) would help reduce the behavioural issue.
Doesn't meson bring in all of python3 as a dependency for a project? Similar to scons.

(It's been a while since I did semi-serious C++, maybe nowadays we're playing a bit more loose with deps and polyglot setups)
hmm not from the crypto-community, but .. find the passengers that are comfortable sharing their weight; gather those, mark them in the total list with a tag, a certainty estimate from 0.0 to 1.0, and a weight. Now use the rest of the list to estimate weights based on similarity, assigning some reasonable certainty; show the other passenger those results, tell them again how the group benefits, and they personally benefit; iterate.. If an individual does not want to publicly share their weight, then show them how they can enter the weight without being named to the group. Iterate that, with their consent.

The reason I say this is because you are not talking to machine parts or to secret financial players, in this problem, to you are talking to human beings. By reducing human beings to machine parts to solve a problem, you are losing information that is critical to your own humanity ! and to theirs ! super-bad results can happen when people in power and their adjuncts, are successfully rewarded for reducing human beings to machine parts in their solutions ! Junior programmers finish your studies, but all humans please take note -- no cryptography required here !

Um, what? What is inaccurate about the PCR?
I like this better than my solution. The technique of adding random numbers has a more crypto feel to it. It would help to use big numbers, so that they would conceal the underlying number better (clearly single-digit numbers would be no help, might as well extend that and use 5-digit numbers).

Sure, but you're not designing interfaces and technology for those that aren't online, are you? Like, you're not making an app for rural Pakistanis that can't read and don't have smartphones.

The whole world might be online at some point, but you'll still not design your apps for Pakistan, because the difference in adoption speed of technologies, trends, cultures etc will not go away just because they are technically online now.

That's not to say that Pakistan itself won't be a strong market to target. But It's a niche market, you'll likely not target the US, Pakistan, and France in one app, just like you don't today.
Here is a discussion on Channel 4 on the approach taken by the UK government.

https://youtu.be/C98FmoZVbjs?t=590

Debating are:

- John Edmunds: a professor in the Centre for Mathematical Modelling of Infectious Diseases, London School of Hygiene & Tropical Medicine

- Tomas Pueyo: his modelling of the pandemic has gone viral on the web: https://medium.com/@tomaspueyo/coronavirus-act-today-or-peop...

During the debate, Pueyo throws up his hands in horror at what the professor says. Listening to them both, I honestly don't know who is right. You may think a level-headed response is the right approach rather than an emotional one. But there is something cold, clinical and unemotional about the UK's strategy to tackle this pandemic.

And can you "nudge" people to adopt certain behaviours in one country when the rest of the world is doing the opposite to what you advocate?
What would testing easily available for all mean for the control of the disease? When vaccines or even treatment is still a while away, could this help?

E.g. if a country could test 10% of the population in a month, wouldn't that help the "everyone is a potential bearer"-lockdowns we see now and help achieve some normality? Or is mass testing too expensive or wasteful? Or would the information not be valuable enough to do it?
I'm not sure what's what 'worthless' means.
There's also the "Digital Ocean Killed Our Company" event last year https://news.ycombinator.com/item?id=20064169 that seems to be fresh in people's minds, but honestly that seems like a bad luck one off rather than something endemic in DO.
I think the more modern equivalent would be making games with various javascript game engines (twine, etc) in a web browser or similar and making art with medibang paint and so on.

Then there is the entire linus tech tips make a cool RGB flashy gamer computer and poke at shit, where those kind of tech youtubers make get a million views per video.

You can open up the two files in a Hex editor. If there's any differences it'll only be in the header which is a quick fix.
That’s incredibly short-sighted. This is a lethal disease that’s spreading rapidly across the entire world. Even if you personally don’t die or even feel sick, you could easily pass it on to others who do.
I'm not sure if the great article backs up the thesis necessarily.

Trying to be 'Tiger Woods' by specializing on Golf is probably a recipe for disaster, but focusing on say, 'being a Doctor' from late high school can be a good winner. As the article hints 'the rules are clear' for being a doctor.

Given the clarity of the rules, the 0% unemployment rate etc. 'Doctor' might still be the best profession out there. Surely you can make more at an investment bank, but many (most) do not, whereas if you're an MD you really have to screw up not to do well if you're trying to.
