I think it would be more precise to say "The best way to understand elliptic curve cryptography is to study discrete log cryptography, not to study elliptic curves".

There is a tremendous amount of ECC tutorials that walk people mechanically through the group law, I think I've seen a dozen new ones posted on HN in the past year. I don't think I've ever see an article on actual elliptic curve cryptography (beyond briefly explaining DH, as this one does).

Like-- say the article were instead explaining elliptic curves as part of factoring, how would it differ? (This one would omit the DH part, but many don't even have that.)

Personally, I think they're not that useful from the perspective of cryptography. This level of article doesn't bring you to number theory insight or anything like that. They are useful for slavishly coding your own ECC thing without any understanding, but the results of doing that are inevitably totally insecure toys. Hopefully that isn't something "most practitioners" are doing-- hopefully they're linking libsodium or something. :)

If you like it, great! I think I provided a pretty useful curriculum that someone could self-study if they wanted to actually dive deep on the cryptography.
Pluto’s Atmosphere Predicted to Collapse by 2030
Well it's none of my business and after the story you've shared I can't say I am very concerned. But in the story about HR, they looked into it and there was "other stuff", I guess they concluded something else about that situation.

We don't know what that "other stuff" is and if it's right or wrong, but it's also likely not the exact same situation as your very detailed and specific story, is my point.
Having a redundant comm system in an area prone to destruction of telecom infrastructure, e.g. fires and earthquakes, seems to be a no-brainer.

Removing them sees to be idiotic, at best. And callously reckless at the worst.
wow, that's very scummy. That must feel worse than them finding you because you slipped up technically.
Meetup works really well in my city. Recently a few friends started a meetup group for a taco night with other folks in the tech scene- no speakers, no frameworks, just some people getting together after work. Some of the group that set up the event came, but because it was on meetup, several total strangers joined us and we all got to hang out and shoot the breeze. Several of the people who showed up were people working remote jobs who don’t have an after work socializing option when they want one.

Thanks one example, but shows the overall idea: anybody going to a meetup event has already accepted that this a publicly known event where there will probably be some new people, and wants to socialize with new people too.
> Awesome!! It's been disheartening to see flotjs (which was essentially unmaintained for 5 years) still beat out scores of other charting libraries in terms of raw speed.

i should add it to the benchmarks :) probably based on https://www.flotcharts.org/flot/examples/axes-time/index.htm...

> Over the last few years we've tried a lot of different techniques, eventually settling on using Vega with our own interaction layer ontop- but I'd like to give this a try. I'd love if this library handled the sizing of all the elements as vega would

i'll add Vega, too based on https://vega.github.io/editor/#/examples/vega-lite/line

as far as label/element sizing goes, right now uPlot's labels are just absolutely positioned divs; vega's are canvas text. in addition, uPlot simply blows away and re-creates all labels on each zoom/unzoom action - far from ideal, but more than fast enough for manual ranging/zooming. i could potentially move to canvas text as well as a starting point, but there are many trade-offs to consider or whether it's necessary at all. i would like to see what type of label sizing you guys take advantage of with Vega to understand how extensive the implementation would have to be to offer something similar.

> One of our use cases is streaming high frequency data- do you still see uPlot performing better than the alternatives in that scenario?

that's a loaded question. and the answer is that it really depends on the frequency and the amount of data. if you can give me a function that simulates the type of data feed & rate you're dealing with, along with how much data you expect to be shown at any one time, then i can give you a better answer. right now, if you open the benchmark in the repo and toggle the series on/off while recording perf in devtools, you'll see that it takes ~12ms to redraw the 170k point chart, which includes auto-scaling. this is enough to do 60fps, but does not leave much frame budget for much else. in a real streaming case, i would expect the actual numbers to be much lower than 60hz data updates and much fewer than 170k concurrently displayed points. in addition, i would probably turn off auto-scaling, since it would be very distracting to have the chart rescale constantly.

if you'd be interested in providing a data stream simulation, then we can work through an example. feel free to open an issue if you're interested in fleshing this out.
I’m having a hard time reconciling this uproar when everyone is fine with the sanctions on Cuba, Iran, and Venezuela.

I do find it interesting that all of this is happening during thr president’s possible impeachment along with the recent ruling that Americans were illegally spied on.
At one point I considered learning Dvorak and then having a password that was using the Dvorak key layout but on a Qwerty keyboard.

But I only made it maybe a month into my Dvorak-learning efforts. Just not enough benefit for the added hassle.
Maybe "friendly" in the sense that both sides were deliberately ignoring the things they didn't like about the other in the interest of keeping global business chugging along. But not actually friendly. Part of the reason things heated up so quickly is that there was a lot of stored propaganda ammo to use. For example, US condemnation of China's human rights violations dates back decades, and only got swept under the carpet by Clinton in the interest of pumping economic ties instead of continuing trade sanctions [1].

It is inevitably going to get to that point. The protestors will not quit, so it will end in genocide or guerrilla warfare through the streets. Give it a few more months.
Hams at their own expense create and maintain a statewide emergency communication system and some government bureaucrat on a whim wants it all disbanded.

So the next time a city or state needs ham volunteers to maintain communications during an emergency they won't be able to do it. Even for California that's pretty fouled up.

My local club had a partnership with the local Red Cross, had our own club station and held meetings there for over sixty years. Then a new manager decides he can use the room we were using in the basement and kicked the club out. Sadly there was no appeal. I hope the California hams have better luck.
> ...when it could generate $300,000 in revenue over a decade?

If markets are competitive the profits will be lower. If markets are not competitive (not many companies can make or license self-driving AI) the rest will sell cars with steering wheels.

The variable that is actually important is demand. If lots of people want their own car, or want to drive their car, the market will provide those things. If most people are content to rent, ownership might become an unusual luxury.
Thanks for the suggestion :) The is kind of semi dirt and blends with its surroundings though. I will keep this in mind as an augmentation maybe.
While I've always respected the West's stance on their own judgment of values, and the continual holding of it, I'm saddened by any narrative that it's in the face of morality.

Morality is an entirely subjective concept, and should not be used as a weaponry. The West has developed for many years and have ascended through times from ancient religious principles to the notion of modern basic human rights. However, I'd like to address that by saying the notion of "basic human rights" isn't universal, it's a standard of the West. The East doesn't do it perfect, but neither does the West. This whole affair is an eventual reality that happened to spark in the era of our existence, due to an inherent ideological difference. This is no right or wrong here, only a side to take, but to attack the opposite side of being immoral based on one's own judgmental system is simply not constructive.

As humans, the least we can do is to be aware of the situations and stay open minded and be respectful of each other, and our differences. That's how we can together evolve to a possibly harmonious future, at least to the extent of the upper-bound of humanity. There isn't a single standard of morality, and a heavy indulgence on one single side will eventually run yourself into a corner of being seen as practicing double standard.

Let's call it for what it is, a challenger to the current supremacy and that's that. Conflicts arising due to ideological differences is hard to resolve, but to only address the other party as immoral is an extremely short-sighted strategy to addressing any differences between the two. It's a greatly sad affair to see the propaganda machine on both ends flexing their muscle. Either the challenger will be defeated and we accept a new reality, or the existing supremacy loses and accept itself as a second. Bringing in a self-righteous morality to the mix is only going to incur permanent damage to humanity as a whole by prolonging the battle between ideals.

I’m not sure he’s up to the level of Stalin, but he’s sure purged many of those whom he thought might threaten his standing —most under rather made up circumstances like corruption, where you know, everyone is corrupt, but they all play the game, except if you’re out, then of course, you’re denounced, striped of property, put in jail, or worse, depending. It’s so reminiscent of soviet politicking.

They did, but the court fees were high, and are high enough to dissuade people who aren’t billionaire talk show hosts from saying similar things. As I said, America is quite good at free speech. But it has its gaps, much like most other countries which would self identify as free speech countries. In the grand scheme, they really don’t matter.
It feels like I am watching Idiocracy again. Someone really wants California to burn. Isn’t there some president who does not like California..?
I'm possibly only aware of Millard Fillmore because of the Infocom game "Bureaucracy" and oddly enough:

Back in the 80s I worked in a place running on Apple IIs

The biggest problem we had then was floppy disks physically wearing out, as they were running all day

Did someone corner the market in 5 1/4 floppies to handle cases such as this? Does this museum have enough supply to keep running?
I too wonder how the nytimes seems to be pushing an agenda of isolationism, whereas that used to be a policy of Trump - and the nytimes used to oppose Trump. Is it possible that protectionism is now part of a consensus thing in the US?

It still may that all of this is for show and part of the trade negotiations, go figure.

How does Codelf help you to name function/variable better?
There's been a push in recent years to free up parts of the amateur bands for auction.

It doesn't seem particularly well thought out, to be honest. Power usage and interference are among the reasons that you probably don't want to own the amateur band... But some companies disagree.
thanks for the reply! i'm gonna need some time to mull it over...

would you be able to say how "normalizing" fits into this? by "normalizing" i mean applying some function that takes each equivalence class to a representative element (think simplifying fractions). using something like that, we could round-trip a value (object -> quotient -> object), though at the end we might end up with a different value than what we put in. so yeah, a normalizing function seems like a useful thing when looking at quotients constructively. sorry for the handwavyness, i hope i managed to get my point across!
> I don't know what it would even mean to have a "hard fork" which does not maintain the previous state of the blockchain.

Some of these things have edited the prior state... heck even the purpose of the eth/etc hardfork was taking coins from the 'dao hacker' and assigning them to the ethereum foundation. There was some "united bitcoin" where you had to transact during some particular window to get granted coins, etc.

I agree that the case where there is a fork and where you don't get coins is degenerate-- plus the tax treatment in that case is obvious.

The New York Times must have a policy that it will not publish an article if it doesn't have at least a couple snarky digs at "capitalism" and Trump, no matter how tangential to the subject matter.

What other countries USA is friend with has concentration camps? Turkey and Saudi Arabia have problems but I believe human rights situation is better there than in China. What else?
Not really, it's really the result of Xi's consolidation of power. People have been writing about this for a long time, but no one was reading until now.
A few years ago, South Korea's then conservative government decided to let US force build an anti-missile radar facility called THAAD, which conveniently was powerful enough to see through Chinese airspace up to Beijing (or so I've heard). Of course China didn't like it - and actually a lot of Koreans objected to it, viewing it as needlessly putting ourselves in the middle of geopolitical game between two superpowers.

But then China went completely overboard, banning Chinese tourism to Korea, and forcing out many Korean companies from Chinese market. And to what end? It hurt Korean economy a bit, but the primary effect was that Koreans' opinion on China cooled down remarkably.

As some of you may remember, the conservative president got kicked out in 2017 amid national protest - we now have a reformist president who is less pro-American than his predecessor. If China waited just a bit, they could have negotiated a better position. But they had already played their cards. THAAD is getting built anyway.

It seems China's national pride is getting in the way of their diplomacy.
Chernobyl's Control Room Is Now Open to Tourists
If you're going to run these containers in production [on more than a single host], throw out the volumes and docker compose. Mock up your dev sdlc to work like production (ex. you can't use Docker Compose to start Fargate tasks)

In fact, I'm going to make a very heretical suggestion and say, don't even start writing app code until you know exactly how your whole SDLC, deployment workflow, architecture, etc will work in production. Figure out all that crap right at the start. You'll have a lot of extra considerations you didn't think of before, like container and app security scanning, artifact repository, source of truth for deployment versions, quality gates, different pipelines for dev and prod, orchestration system, deployment strategy, release process, secrets management, backup, access control, network requirements, service accounts, monitoring, etc.

The reason to map all that out up front is to "shift left". If you do these things one at a time, you lose more time later as you slowly implement each piece, refactoring as you go. Whereas if you know everything you're going to have to do, you have much better estimates of work. It's like doing sprint grooming but much farther ahead. Figure out potential problems sooner and it saves your butt down the road. (You can still change everything as you go, but your estimates will be wayyyy closer to reality, and you'll need less rework)

A weird comparison would be trying to build wooden furniture without planning out how you were gonna build it. You can get it done, but you have no idea if it'll take a weekend or two months. Plan it out and you can get more done in one shot, and the quality even improves. This is also the principle behind mise en place.
I'd like to add an additional possible threat model that gets ignored pretty comprehensively and, in some cases, intentionally: Your data being fed to automated systems that provide summaries or derivative information based upon your data. People ignoring this is behind much of the NSAs snooping. They believe that until a HUMAN operator views the cleartext of some communication, the communication can not legally be said to have been 'intercepted' at all. And if you look up any statement ever made about reforms done at the NSA after Snowden's revelations, you will find that all of them, every single one, spoke exclusively about human analysts reading communications directly. They avoided addressing analysis, profiling, ML training, summarization, and other automated things very intentionally. The government has dropped a good many cases, serious cases involving child pornography even, to avoid ever testing this idea of theirs in court. We learned about this particular legal opinion of theirs (which would almost certainly never survive any court challenge at all) before Snowden even, back when the AT&T whistleblower came forward.

The likelihood a company like Google is reading your emails directly and trying to scoop your business on a product idea or something like that is slim. The likelihood they are profiling your communications in aggregate and producing derivative information like "how many companies in the space are considering hiring" or "do the employees at this company talk about Chipotle" and using that for advertising or data products is, I would guess, pretty high.
Nope. I want things to look plain and simple. I want to use fewer cores for longer battery life.
Self driving cars that can't operate in heavy snow or rain will be totally useless.

One of the lessons of engineering history that self-driving car proponents fail to grasp is that promising technology often fails to get traction because it can't close the final 5%. Supersonic aircraft, for example, have effectively been derailed by people on the ground near airports complaining about sonic booms. VTOL aircraft never replaced aircraft because of control problems. Flying wing aircraft never became popular for similar reasons.
Issue is, China is attempting to to force its viewpoints on other nations, eg. by denying prize money to the winner of a tournament for speaking about Hong Kong, and something about NBA I didn't follow.
What playing their hand too early means is that they’ve hurt themselves with dumb moves. What good is having influence if China use it stupidly, makes everyone pissed off, and everyone closes their doors to China? Xi and the CCP have hurt China here.
Despite its drawbacks string theory may actually be our best theory of quantum gravity, perhaps even enough to justify its hiring ratio relative to other quantum gravity theories. Maybe string theory has been treated in a balanced way all along.
I have to agree with geowwy on this one. I think the issue is more that China hasn't been playing by the US's normal business rules for a while now, while most other bad actors the US is friendly with do play. For example, currency manipulation, outright IP theft, state-sponsored propping up of US business clones, mandatory dual-ownership of companies, and now strong-arming US companies if they want unfettered access to the China market. Enough influential people's feathers got ruffled to get the ball rolling, which just happened to coincide with worse-than-usual human rights violations.
Yes four separate differences.

Under Mao, despite an ostensibly strong social net, many still starved to death. I intentionally listed those two together because Mao time was not so great for many.
I don't think anyone wants to dissolve any network. From the state letter (the histrionic complaint to which it is attached provided no useful additional information, but a lot of hyperventilation and irrelevancy), it looks like the State has been allowing collocated private ham radio equipment with neither formal agreement nor any charge on State property based on historically perceived public value (without such policy value, it would probably be, legally, a gift of state resources to a private party, which is prohibited), which it has reassessed and found no longer justified, and it has therefore provided notice that henceforth, a formal lease will be required for this use of State property.
Generally, it's nigh impossible for a military force to take on an insurgency embedded in buildings throughout. That is, unless you deploy scorched-earth tactics which China may be ok with.
At least you're not monetizing yourself with big brother google tracking all of your driving data in order to better serve you ads.
Gartner marketing hype
Yeah, violence should be a last resort. I think his point was deterrence, though. If the British had allowed HKers arms under colonial rule, would things be different now? I’m guessing China would have attempted disarmament as soon as Hong Kong returned under their control, and today’s situation would be the same.
How many cars can one employee be "inside of"? If that number is an order of magnitude higher than 1 the cost of these employees is probably relatively negligible.
Apple removes Quartz news app in China
Read the actual judgement, and it's just about impossible to conclude that the conviction was anything but deserved and perfectly balanced.

The judge explicitly asked his defence to explore freedom of expression. He chose not to. The rest of his "defence" was laughable and easily disproved lies. The judge pointed out his failure to explore freedom of expression in his summing up. Short of using neon, how much more clearly could the judge have telegraphed it? The conviction was therefore on pure technical breach of the law with no mitigation.

Markus Meechan was left looking like a complete moron who threw away his opportunity of defence. In addition to being a bottom feeding racist. Oh, and a scammer as he crowdsourced a load of money for the defence he didn't bother offering.
Tons of them? I don't think any of the parks around here in exurban maryland have any sort of special speed zone. My 100+ year old neighborhood doesn't even have its layout mapped correctly in Google Maps. (The road names in the app don't match the street signs and the wayfinding doesn't realize that the road in front of my house is segmented with barriers so you can't drive all the way down it.)
