There is, but it's not a special operation: it's called scalar multiplication and it's just a lot of grouped additions.

If you want 13P you do

2P = P + P

4P = 2P + 2P

8P = 4P + 4P

12P = 8P + 4P

13P = 12P + P

To use this for encryption you do a Diffie-Hellman operation, where A and B pick secrets a and b, send each other a x G and b x G, and compute the shared secret a x b x G = b x a x G. (Where G is a standard point.)

You can call "b x G" the public key and do ephemeral-static DH if you are not doing a key exchange between two online peers.
This is shocking and should absolutely be more widely reported as it may change behaviour of present day activists. We need an anonymizing solution for protest organizing.

ISS was built with lots and lots of really, really, really expensive Shuttle flights.

The Skylab was 1/3 the size and only needed on launch.

The price of making a station also goes down massively with the going down of general launch prices.
I guess that is more about hiding the identify of the photographer instead of the people pictured, but since browser fingerprinting works by combining seemingly innocuous data to identify individuals, that suggests that removing everything is probably safest. The camera model, software versions and other explicit labels are one obvious thing. The ISO, focal length, and shutter speed could narrow down what sensor was used and maybe what software, especially if you had multiple images from the same camera. Maybe manual settings changes that the photographer made could show up in the same data. Possibly small amounts of clock drift? If you saw the news story that combined multiple security cameras' footage with phone video around the time of George Floyd's arrest, clock disagreement was something they saw, and the events in the images themselves allowed them to figure out the clock difference (which was huge there, like 20 minutes, but you could still do for a smaller drift.)

Other things are external to the EXIF but could be combined with it. The sequence numbers in the filenames are the most obvious signal. The precise number of megapixels of the image might also tell you what sensor was used -- so maybe an anonymizer should resample the image to a new size.

I guess these seem unlikely to be investigated, but then again nobody initially thought that telling every web server what fonts you have installed on your machine would be used against you, or that the existence of "Do Not Track" would make browsers easier to track. It just depends on how much it's worth to someone to write this stuff once -- then it's free for all future uses.

I just looked at https://en.wikipedia.org/wiki/Exif and there are lots of interesting possibilities.
Fountain pens are nice to write with for really long handwritten documents, but I do that so rarely these days that I spend longer cleaning out my pen to get the ink flowing than I do actually writing. That says far more about me than about fountain pens, however.

I have a Lamy with a clear grip so that you can see the feed--not sure which model. I also have a Pilot Metropolitan, which has a better seal and doesn't dry out as bad when it's disused.

I kind of want to get myself an electric typewriter so that I can write comfortably without really being able to edit (to force myself to keep writing instead of going back and editing), but I know that it will end up in disuse after writing a few dozen pages with it. My Apple Magic Keyboard, my full-size mechanical keyboard, and my ThinkPad's built-in keyboard are the only writing devices that get much use for me anymore.
My hope would be that all (or at least most) such new space stations would be "international" space stations. Stations should be differentiated by purpose rather than nationality, I think. Space doesn't have borders.

But yeah, this is definitely a reason why I hope we can keep the ISS going and just keep building on it. Additional space stations should be for good reason (for example: orbiting the moon, or - my crazy dream scenario - one orbiting in the past-GEO graveyard orbit to collect and refurbish dead satellites).

That means we should allow China to participate in the ISS, too. There are some national security concerns, apparently, but we overcame those with the USSR/Russia, and China should be no different.
That more aggressive policing causes an order of magnitude more crime seems like a theory that doesn't pass the smell test to me.

Is there a good reason to believe that it's true?
I would highly recommend the TWSBI Eco as a starter pen close to this price range. Piston-filled with a massive capacity, and comes with all the tools to disassemble and clean.

I think if you are going to claim a tool is "best in class" then it should be demonstrably better at meeting the actual needs of people doing what it's used for.

The list above was a list of features, not a list of benefits. Those features might bring practical benefits to the working web developer -- after all, people who program in Haskell do so for a reason, which is probably that they believe this kind of language is helpful in some way -- but that has yet to be established here.

Meanwhile, an experienced back end web developer will probably be asking questions about managing large numbers of routes or guarding against common attack vectors or integrating with databases or calling external APIs or having a template system that supports translation to multiple (human) languages or understanding performance characteristics and how the servers will react to higher loads. These are practical matters that many web server frameworks attempt to address. It is revealing but not entirely surprising that the Haskell response to my question was instead to talk about strong typing and STM and so on.
This doesn't pass the sniff test. If they were rioters, they would likely not be rioting on their own porch. Hence, ordering them to go inside would mean breaking into someone else's house. On the other hand, if they're legitimately on their own proerty, and if they're not being disorderly, then what is the rationale for that use of force?

I hate to say it, but I'm doubting the veracity of this account. There's nothing in the video - trash or debris from a large crowd, in particular - to indicate that the area they were in, specifically, was in need of such force. And, again, the curfew did not forbid being outside on one's own property.

If we're going to second-guess what we see with our own eyes - that these people were shot at by police without provocation - it's perfectly reasonable to then continue to drill down on what happened; question accounts, question logic. Or, we could employ Occam's Razor.

Anyway, as a practical matter we should also be asking for the RUF that these police were operating under. That would clear up a lot.
No idea, to be honest. In fact I run a (web/mobile) startup now so it isn't even my industry anymore :-)
From his about page: "I studied music production in college, and after seeing the ambition of SpaceX, and the excitement in the new space industry, I was hooked. I wanted to work in aerospace... "

At first, I wondered what SpaceX role would suit him best and why SpaceX hadn't hired him. Then it occurred to me that humanity might be better off with passionate polymaths such as him working outside as opposed to inside the establishment. After all, Elon Musk started his aerospace career outside the establishment. And SpaceX is now establishment?

Polymaths have been quite productive in crypto and other low-startup-cost environments. But, apparently, not so much in autonomous vehicles, etc. This could be a function of the learnings required for physical world projects, to wit: quaternions, telematics, aerodynamics, etc.

So, would we/he be better off inside or outside the Borg? Thoughts?

I agree, and I'd go a step further and say that if you destroy evidence of someone burning my city down or looting, you're an accomplice to that crime.
You could stream to your computer at home and then to the world. But it's weird that the live streaming websites don't offer it as feature.
The more that protestors refrain from violent property destruction, the less likely it becomes that the three cops who were accessories in the murder of George Floyd get charges brought against them. Burning down one precinct got one cop charged (albeit with a 3rd degree); I would really love to see the other three charged, even if it requires some anonymous protestors to light up three more precincts. I'd gladly trade in police destroying citizen lives for citizens destroying police property.
I've been looking for an oscilloscope for almost a decade now. Every year the cheapo ones get better but they're still very limited IMO and feel very expensive for what little they do.

As far as I can tell the Analog Discovery you mention is quoted by Digilent at $279 and for this price you get two 100MS/s analog inputs, so that means that you can't sample anything above 50MHz max (and in practice you probably won't be able to do a lot of useful work above ~40Mhz). With modern circuits routinely having signals in the hundreds of MHz that's fairly limiting for me.

And if I just want to probe "slow" digital signals like SPI or I2C I can get 90% of the features of this module by using a cheap-o ~$10 Saleae clone off aliexpress. It's only a digital analyzer but it goes up to 24MHz and with 8 channels you can already do quite a lot of work for a tiny fraction of the price of an entry-level scope.

Of course if you do a lot of analog work then a digital analyzer won't cut it and the ~$300 price tag for a basic scope is almost a required purchase at this point.
Initiative doesn’t mean they follow it, especially for legacy projects.

While I do think that Apple is using privacy mostly for PR, I wouldn’t be too cynical. It’s likely that new projects are built with higher privacy standards. But also, I wouldn’t be too surprised if their PR department is writing checks that their engineering teams cannot fully cash.
Using this strategy docking is much, much easier than trying to follow hexagons.

People are downvoting you in good faith, and they're trying to disagree with you and send a message. If we look at your comment history, your comments are you plugging your own personal project. And you keep getting downvoted because you are hijacking the conversation and redirecting it to something you built, that people did not explicitly ask for or express interest in. And so when you keep doing that, people will feel like it's spam. To make matters worse, instead of taking the subtle cue of a downvote to mean that you're doing something wrong, you seem to deny that and instead conspiratorially deflect blame and personal responsibility towards someone else.

My suggestion is to submit your product as a new post. If people do not express interest in it, that indicates an issue with how you have designed your product, or marketed and positioned it. Take the reception that you get there, whatever it is, in good faith. It's clear you have a lot of ideas around your project and what motivated it that pertain to society at large. That leads me to my second suggestion:

Try to consider what your values and beliefs are and how you would respond if you were not working on this project. This is your null hypothesis. Try to think about your project the same way others will, which is that without momentum it will likely fail. Make conversation based on that. And then, if you find that people are interested in what your values are that lead you to start this project, maybe after they express interest, gently plug your project. But if you try and shove something people want down other people's throats, you're just going to alienate others and drive them away. And then your project will fail, as it should, because you didn't build something that people truly wanted.
I recently found out about an app from the ACLU specifically for recording//reporting (abusive) police activities.

The app itself, at least the California version, has a section regarding one's rights and safety whilst filming police.

Classical/Lyrical/MT (what is MT?musical theater??)styles do not require "more" technique. They require different techniques that have a long pedagogical history. The style is not harder to teach. Classical music has many styles (Renaissance, Classical, Romantic, Chanson, Bel Canto...) and they are all as teachable as popular styles. I guess this bothered me because there is this incorrect hierarchy people ascribe to classical- like it's a higher art or something. This is misleading. I'm a classical musician. If anything, the "training" makes people think they need to ask permission for everything and keeps them chained to someone else's ideas and removes a lot of their own confidence. Then, they spend the rest of their life trying to undo this damage while they try to sing show tunes with some kind of relaxation "of the street" and without constant judging of themselves. See: Dawn Upshaw's popular musical recordings or Renee Flemming's.
Took a quick look into their GitLab account and they seem to use some continuous integration, which is a native GitLab feature.

Gitea does integrate with some external CI/CD services, but it's not a part of the core product: https://docs.gitea.io/en-us/ci-cd/. Gogs makes no mention of CI/CD in its documentation.

I've switched from Gitea to GitLab for that same reason for my personal projects, and I'd bet that's by far the largest selling point of GitLab when compared to other self-hosted solutions. You just do a "git push" and stuff gets automatically tested in a VM or even deployed in a live environment.
When I hear your first point, I consider the possibility that these are not retaliatory murders, but rather ways to keep something secret. If there was an agenda behind these riots organized at a higher level than these leaders, similar to what is being suggested by some during these current protests, and those higher level organizers wanted to keep the agenda or those who set it hidden, it could explain why lower level leaders are being picked off.

Edit: For those downvoting, is there a problem with considering this possibility? I think it's incredibly unlikely, but ignoring black swans can one day come back to bite you. Ideally, everyone should be aware of the theories out there, however ludicrous, on the off chance that they are correct and require critical and swift action.
There will be some information loss from edge effects and quantization noise. But mostly invertible.

I think its really a matter of opinion and choice of development. Some people want to build it themselves, others would prefer to use a standard. Its the difference between using Spring or writing tools around Java. Using small libraries or Ruby on Rails.
Verba volant, scripta manent. Ancient Latins already knew the score. A lot of people initially refused to use emails in the ‘90s because they (rightly) perceived it as something written down and hence likely to be used to hold them to account - only people who grew up with IM have a more “disposable” view of electronic text.

I can assure you that any manager or owner on the planet, at some point or another, has a conversation where it is agreed that something will never be written down in any form.

In the case you posted, the image is not blurred. Instead pixels are simply moved from one location to another via the "swirl" effect. Very little pixel information is lost in this process, and if you can recover the position transformation, you can easily undo it.

Ask HN: We exploded and now its messy – how to organize a remote team?
We are fortunate that the current situation had a positive impact on our business (b2c saas). My team worked remotely all the time, but grew from 3 to 11 full time employees within two months, and now organization is a mess.
How do we organize knowledge and todos? Whenever I tell/request someone about something, i have to keep it in my mind because I fear the other one is forgetting about it.. that gets super stressful and annoying! Same goes for ideas, concepts, notes or emails.
We use trello, jira, confluence and slack.. all good tools but but that doesnt do the trick if you dont tackle it with a plan. Please help!

There's data like the camera model which can be used for de-anonymization. Though, if de-anonymization is a concern in your threat model, you need to worry about sensor noise providing a unique fingerprint:

I agree with what you're saying, but I think it's important to understand that the actual politics of reform pose a serious obstacle to admitting biases exist. If a police department produced a document saying "10% of our officers are moderately to severely racist, we're aiming to get that below 3%", they'd be eviscerated.
Conference on Computer Vision and Pattern Recognition 2020 with Satya Nadella
For those who do not click through to the article: “Police say that there is no evidence the deaths have anything to do with the protests”.

From my time in Portland, working at the courthouse as a court clerk during the Occupy movement, when hundreds of transient “protesters” camped out in the park, it is not surprising that some of those folks would OD or end up dead for reasons entirely not related to protesting but instead related to their unfortunate life circumstances. I do not know if the same is true of Ferguson, but the article does not seem to provide any evidence of calculated retaliation against protesters.

What if you stop an EMT from checking the pulse of somebody who your co-worker has been choking to death for minutes? Does that make you an accomplice, too? If your city charged these cops justly then nobody would be burning it down; cure your disease and the symptoms will go away.
Personally I love programming, among other things that people might regard as similar to programming.

The prospect of just sitting in front of TV and going for walks is horrifying. For short breaks, sure, that's really nice. For years? Horrifying.

Solving technical problems is vastly more satisfying than that.

It's like maths to a mathematician, physics to a physicist. Why would they ever stop, given freedom to carry on?

I would love to be able to retire for the freedom, but with that freedom I would want to build technology, much as I do now except I'd choose the things (and they would be much better things!)

(It might be that the kind of programming you do in your job is a very different thing though. I'm not excited by writing more business forms either. Programming is an extremely broad term these days.)
What you wrote is what I would have guessed. Are you also guessing or do you know for sure? It sounds right, but I'm very curious about the actual answer to this question.

Well, but the Shuttle SRBs were reusable.

you just can't imagine how few Google engineers are responsible for how many products and data integrations

If Google was a scrappy startup with a few dozen employees, people might be more sympathetic. But Google has hundreds of billions of dollars at its disposal to fix the problem. It could purchase a small country and employ every person in that country to fix its problems. But Google won't admit that people can do what algorithms can't, and that's what causes Google to get so much hatred from the public.
