Two duress codes--one for you, and one for your counterparty. Thus, the bi- in bi-deniable.

Mono-deniable gives a duress code only to the sender, or only to the recipient.

The paper claims an additional category of bi-deniability, such that your duress code and your counterparty's duress code produce different plaintexts, rather than the same plaintext. It is unclear from the abstract whether it is possible to have a bi-deniable scheme without this property (which does not also require prior coordination between parties).
Seems slick but pretty pricey ...

It is not necessarily a win. In the case of highways, often times new greenfield development that is spurred on is just development being reshuffled across the region, so you spend money to make the same amount.

It’s true that transit doesn’t solve congestion; however, it provides an extremely high capacity alternative. Speed and reliability of a highway lane is approx 2k people per hour, but try nudging past that and you start getting phantom traffic jams. The New York City subway has a theoretical peak capacity of 60k people per hour.

I'm not necessarily of this opinion, but his view is that knowing what you had for breakfast and your address is the same as your bank account # or house keys; it's just that people haven't realized this yet.

Their argument is that the reason why people say house keys, or bank act # is different is because they are protecting something of value. His argument is what you do on a daily basis is just as valuable you just don't know it yet.

The other argument against is "yes my privacy/ daily activity may have 'value', but unlike my bank account or house keys people can't take something from me from knowing it. "
That's more up to opinion, but the argument is knowing you so well, someone can take your independence. A bit dystopian, but imagine n years from now, ML is good enough to predict your responses and behaviors to 80+% of things. Companies now use it to effectively get you to make decisions they want. Combinations of timing, placement, location, repetition, persuasion, counter-argument all to produce a desired result, but unlike present day extremely effective and possibly without your awareness. If there is a way to get our wet ware to do it, ML will figure it out.

Advertising/Marketing/Sales become a game of Go, where you're the Go board. Best ML wins.

We like to think we're fully in control of our decision making facilities, but study after study shows that's mostly an illusion. Our sub-conscience mostly decides for us, and then our brains rationalize this away after the fact.

The fear is that by giving away your emotions, your responses, your ocean 5 factor model, your preferences, your habits, and a playground to test all of this in you are potentially giving up your independence at a future time.

It's all dystopian, it's not guaranteed, but it pans out as all likely directions and very probable tech.

The "feeling of discontent" in France goes far beyond the Yellow Vests protests, which are more like a "Tea Party" populist movement pushing for stagnation and short-term complacency. The low-productivity fraction of their labor force is essentially shut out of the labor market due to a combination of high taxes + extremely hostile regulatory environment.

And no, they can't adopt something sensible like UBI or EITC - not without reforming the way their government is run from the ground up. Which is exactly the sort of reform the "average dudes" that are now powering the Yellow Vests protests don't want. France is FUBAR - "God-Emperor" Macron had been trying to start seriously working on fixing the mess, but he is clearly failing just like his many forerunners.
Exactly. If I'm a driver who loves my commute, I'd be happy getting folks who would rather not drive off the road and onto mass transit.
That's true to a degree, though I still feel like a good portion of the stories are missing details. Their bias really comes out with the stores that they are (and aren't covering).
Of course, but problems around funding are not unique to the US. You still have to make do with that you can get.
> But why should you have to care, why not just sum(range)?

Sure, if you have single infinitely fast CPU. In real life, we have to decompose problem, run it in parallel and compose it back.

> Or @threads for i in eachindex(object) & let the details about how many cores be written once, correctly, elsewhere?

Here I'm explicitly talking about details, how it should be done, importance of composition, monoids etc. I understand, that if someone did it for you, you might not care - well, more power to you then. But some basics rules about Pyton ranges are pretty good:

1. [0...K) + [K...N) = [0...N)

2. Given range [K...N), number of elements in the range is N-K, in case of [0...N) number of elements is N-0=N.

Simple, elegant, composable. I can't say the same about Julia

Don’t confuse this with George Jetson’s flying car. These are primarily for flying from helipad to helipad. Getting the bigwigs to meetings during the day and perhaps from/to a suburban airport or landing pad for commute, with the last mile issue addressed with a standard car.

There are inherently many constraints in this type of market. Building owners are going to charge for access to their helipads. The fare is going to compare closer to hiring a helicopter than hiring an SUV rideshare. The approximate 50% duty cycle means roughly doubling the fleet size to eliminate gaps in availability. And finally, Aviation Authorities will limit the number of craft simultaneously operating in a given airspace.

Kafka's parent company Confluent becomes Sequoia's fastest ever growing startup
Even "hard" sci-fi can make a few changes to the universe, or speculate about something. Hardness is a spectrum anyhow, but a lot of us see hardness as being more about having rules, following them carefully, and letting the rules participate in the driving of the story itself, rather than that the rules must be exactly and only the rules we currently believe the universe follows. (Which are, incidentally, known to be incomplete, so even that's not really attainable.)

Greg Egan, for instance, has several stories that can only be described as quite hard, but are based around entirely different physics, not merely tweaks to ours, or are based around particular models of black holes that can't be proved, etc.
What a fantastic article. Thanks!
While I agree with you that the homepage doesn't do a good job explaining what Circle CI is to someone unfamiliar with CI, your criticism of the video doesn't make much sense to me. The video has a voice-over explaining what Circle CI does, and includes subtitles for when you don't have sound.
Agree strongly ClojureScript - shame it has a terrible name which probably means it won't gain the popularity it deserves. I've also heard good things about PureScript.
It might be that data protection regulations start to 'encourage' movement in this area regards more careful consideration of the software dependency chain. If you pull in a malicious dependency which results in personal information being exfiltrated, I doubt the "we pulled in so many third party dependencies it was infeasible to scrutinise them" defence is going to mitigate the fines by very much.

Major Internet disruptions in Venezuela amid protests
Ask HN: 20 years experienced developer looking for suggestions/advice
I have about 20 years of experience. I started programming with COBOL and mainframe around 2000. I later moved on to C programming on Linux. Then for the last 7 years or so, I am programming on backend systems mostly (REST).

Unfortunately none of the companies that I have worked in the last 15 years have been financially successful. As a result, I have never worked on high traffic systems (in the range of millions of hits per hour). The busiest programs that I worked on handle a few 100 req/hour maximum.

I live in India (but not in Bangalore). I find it difficult to find new job these days. Most companies reject based on my age in the resume screening process itself. The ones where I get picked for interview, I am not able to clear algorithm focussed interviews, because I am out of touch with algorithms/competitive programming. I've not studied Algorithms in last 20+ years (after college). Nor do I have the luxury of time (kids, etc.) now to prepare for algorithm intensive interviews.

Some startups (remote positions for US/EU firms) that I applied for rejected me as they do not find me with enough experience in high-traffic systems. I have been a jack of all trades and have done plenty of REST HTTP Services, a few bits of reactjs, some amount of Kotlin/Java.

Is there any recommendation from HN for [old] engineers who want to gain experience in high traffic / load systems ? What are the tools, concepts that one must be aware of to work in such systems ? I know that there is no substitute to actual Experience, But, It is a chicken and egg problem for me, as I cannot get an opportunity to work in such problems and so cannot get Experience; while getting rejected by companies because they find my experience lacking. Can you recommend some courses, techniques or other way by which I can gain high traffic software management knowledge imparted to me ? Thanks.

Which is why every aspiring egalitarian society work hard to take the parents out of the equation. Day care in Sweden cost like €100, and you get that in cash benefit for having a kid, which means it is essentially free. Successful societies aren't in effect more sophisticated, they just make it easy for themselves from the beginning.
While personally I don't think anyone's work can be worth billions a year, I don't think people necessarily have a problem with the dollar amount of money that the wealthy have. In my view it's the feeling of impotence and lack of agency people feel. If you work a normal job that most people would expect to work their whole lives you feel powerless for the most part. Your only option is to plug away for an indeterminate amount of time until you retire (?) And it's not guaranteed you'll work there forever as the lifespan of most jobs has shrunk.

It leaves a paternalistic relationship between the business and the average worker. They don't get to feel like they're interfacing with the labor market, they're at the will of their employer. They should be grateful that your employer provides healthcare otherwise they might actually die. Maybe they should open a GoFundMe if they can't afford it. They should respect the patronage of private donations and privately funded grants your city benefits from.

The reason why universal programs are attractive is because they give the average person a sense of agency. Because they're universal they aren't a "handout," they're part of what it means to interact with society. Everyone pays in and everyone gets paid out. But if they're not universal they quickly become handouts for the poor instead of features of society.
Everything you described sounds like blatant corruption or at minimum, extreme selfishness. Im not a fan of conservative politics (grew up in conservative areas), but what you describe sounds like the batshit crazy end of the other side of the spectrum.

Meh, I wouldn't read too much into it. Depending on the country in question, I could easily imagine headlines about "one African dictatorship", "one South American country", "one Eastern European country". True that "former Soviet Republic" is not really relevant, but it's a common (cliched, even) phrase to use once you've decided you need need a descriptor.
France provides healthcare and education. It doesn't guarantee food, shelter, or power. Of course there are relief programs in place if you are without, but there is a substantial difference - as can be seen in any countries welfare programs - between "everyone gets this for free all the time" and "apply and qualify for this limited offer program only if you really need it and we think you do".

The equivalent of the NHS and public education for the later three would be things like widely available public housing with short enrollment periods, maybe even "public" hotels you can stay at. Public food kitchens without needs requirements - just free meals provided by the city if you want them. Free groceries, up to a threshold, per person - something like "food stamps for all". Same with electricity, you could have a "free" amount every month for what the minimum a person should have would be.

Of course when you talk about it all like that you eventually just get to UBI as a means to accomplish all those without the bureaucracy. But as long as France only guarantees a portion of the bottom rung of the hierarchy of needs there will be discontent amongst those who cannot fulfill the rest through the market economy.

I think that's an unfair characterization of numpy's functionality. Numpy introduces data structures not present in the core python library (another one of your complaints about python, though it's not clear to me why it matters that numpy is a separate library), and certain manipulations do not require BLAS/LAPACK acceleration, eg. multiplying an array by a scalar (yes, I know dscal exists in BLAS) or array slicing. Further, it is possible to use numpy without any BLAS/LAPACK libraries at all, and it continues to work (albeit more slowly).
In LA, it highly depends on the commute. For example, friends who work in Hollywood have a 10 minute commute by public transportation (20 min round trip)...but would have a 30-60 minute commute by car (1-2 hours round trip). My commute in the morning takes is 30 min longer by rail than by car, but the commute home is 30-45 minutes shorter by rail...
Cherry MX Browns are reasonably quiet. My local Micro Center has a tester keyboard with a variety of switches that you can try. If you look outside the limited options there, you can find huge selections of mechanical switches that are only slightly louder than membranes. You’re looking for linear or tactile switches and you can find a pretty complete list at https://deskthority.net/wiki/Main_Page in the “Keyboard Switches” section. You can even mod louder switches with O-rings to dampen the noise.

> The government funds primary research that is the innovation behind the technological revolution.

Why is this gospel? Let me tell you two experiences I had:

1) I worked in a bioenergy lab. We were on a DoE grant. The program manager, who had a BA in biology, did not know what a promoter was.

2) I was asked to write a DARPA grant. I did not particularly want to work for the military, but had to as a personal favor. I deliberately wrote it so that anyone with half a brain would look at it and say "that's too little work for two years". It was awarded.

I could go on, but these were the two most entertaining ones. The others are depressing.

What's the point. One. Government science initiatives are run by idiots. This has been going on for quite a while (installing a nobel laureate at the top doesn't matter, as evidenced by the first anecdote), and that's largely because you have to ask yourself "who goes to work in the labs and who becomes a program manager" and when they get "outside experts" usually it's professors and the professor promotion pipeline also is horribly broken away from "competent scientists".

Two: In the context of the bigger question, increasing marginal tax rates won't help. The big problem is that government mostly gives money to the already-wealthy (I didn't get paid much for that DARPA grant, but I can tell you most of the money for the work I did went to the executives at the small company that got the SBIR). Without getting into how this money comes from stealing from the poor, consider that maybe we look at politics wrong - we think "people have no political power because they are poor" and consider that maybe it's actually "people are poor because they have no political power (to get grants, etc)".
I ran into a similar problem, because Facebook is a great way to find family friendly activities going on in my area, and the marketplace / buy nothing groups are good for me as a parent with young kids.

1) Silently disable my FB account, delete all relevant phone apps
2) Create a new throwaway email address
3) Use that email address to create a new dummy facebook account with none of my actual information or friends on it
4) Delete the email address

I now have an account I can log into for specific purposes (like following businesses), but none of the mindless feed scrolling that came with my old account. In fact, the name is so inappropriate and fake, that I can't be tempted to use it as actual social media anymore because I'd almost certainly get reported.

Yes please! Very few companies do this type of dogfooding.
15 years ago adding an external module was an endeavor involving approval forms, lawyers, etc. so that it frequently were much easier just to develop required functionality yourself. These days i still shudder seeing how the build goes somewhere, downloads something (usually you notice it only when whatever package manager being used for that part of the build didn't find the proxy or requires very peculiar way of specifying it - of course at the companies with transparent proxies people didn't notice even that ) ... completely opaque in the sense that even if i spend some time today looking into what is downloaded and where from, tomorrow another guy would just add another thing ...
We usually use CircleCI at my company. I never realised how good I had it until I had to use Travis at my current project :)

To give an example: we have a monorepo and it's impossible to only run the tests of the project that has been updated. Even if you're ready to hack around with git. Even if you're ready to hack around with Travis internal functions. Because TRAVIS_COMMIT_RANGE is just broken.

And your argument "people switch to circle-ci, not sure why, Travis does what I need and I know how to use it" doesn't really make sense, other people would say that CircleCI does what they need and they know how to use it
