Only if things were that simple :) Calvin avoids the need to track clock accuracy by making every transaction go through a single consensus leader which inherently becomes a single point of bottleneck for performance and availability. Spanner and its derivatives including YugaByte DB chose not to introduce such a bottleneck in their architecture with the use of per-shard consensus — this means caring about clock skews for multi-shard transactions and not allowing such transactions to proceed on nodes that exhibit skew more than the max configured. The big question is which is more acceptable: lower performance & availability on the normal path OR handling offending nodes with high clock skew on the exceptions path?
I'm waiting for a lib like Phoenix Channels with a js client that starts with WebSockets and falls back to long polling if things like firewalls get in the way. I actually found Phoenix when trying to solve that usecase in go.

I feel like because of Go's concurrency model, a standalone version of Phoenix Channels (without all the MVC stuff) would be possible to implement.

How much would you like to bet that that rumor was true?
My understanding is that modern concrete is stronger (rebar), ancient concrete was more durable (Pantheon, 126 AD).
The flip side of trying to "solve" that problem is that you then penalise everyone searching for part numbers, which often do look very similar to phone numbers. I suspect they are making an effort to, because I've been bitten by the CAPTCHA-hellban when searching for part numbers. (Likewise, the results there are also often clogged by a bunch of useless sites claiming they have the datasheet or are selling the part, when all they do is try to show ads.)

The change of variable definition, as actually presented in the textbooks everyone teaches from, is horrible. That's the topic of the blog post. Yes, that definition can be made clear after introducing a bunch of machinery of symplectic geometry, but I'm doubtful this is good pedagogy and I'm confident that, due to time constraints, it could never be taught to most physicists.
That looks like a nice second source. I miss the IPA pronununciations though, among other things, so wikitionary will remain my go-to.

Um, no, I'm gonna have to disagree with you on that one. Paying hundreds of thousands of dollars in borrowed money for something which doesn't provide any ROI is IMO bullshit, particularly so if you can't discharge the debt under bankruptcy.

Your examples are bad too, because back in the day all those painters, writers, etc, were either independently wealthy already, or did other jobs before they became famous. H.P. Lovecraft, for instance, worked as a traveling salesman. Van Gogh both comes from a wealthy family _and_ had a job at an art dealer. And there are very few of such people anyway, it's not a viable route for most people, it's more like a lottery.
And it’s a little ironic that JavaScript’s tongue-in-cheek namesake, Java, had grid based layouts in swing 20 years ago.

OTOH, and to be fair, 20 years ago HTML was for newspaper / magazine like text layout, and grid based layouts are great for single page apps. The thing that’s happened more recently than 20 years is the web changed from text & media content in a static scrolling page layout to all pages are applications.
I doubt that.
Too improbable.
Assuming this was a legitimate misunderstanding:

- they earn a $200k salary

- their living expenses match those of a person living with a $60k salary and presumably spending everything they earn after tax (in response to “what kind of life they can live with $60-80k”)

Does that make sense?
Back when http was part of the standard library (I think it was eventually pulled out?), I was building a long polling server with Go and had to fix some stuff to make sure it worked properly. I can hardly believe I wrote some of these patches nearly 10 years ago[1].

With that said, I'm glad to see the Go ecosystem continue to grow. Unfortunately, I haven't used the language for much (corporate jobs were always Java, startup jobs were always JS -- and recently, it's been Python everywhere).

PS: I still brag about Rob Pike & Russ Cox approving my patches ;)

How many files are you talking about? That's the relevant variable, not the amount of data or whether it's text, tabular or relational data, images, audio, etc. E.g. you can copy a single 10 GB file to another drive faster than 1 million files totaling 1 GB, all due to filesystem overhead. If there's a filesystem where that's not true, I'm interested. :)
> Western democracies are very good at monitoring and subduing radicals.

In a way, that's true - democracy is based on some degree of reasonably-widespread consensus, not on what a single power-hungry autocrat might want at any given moment. That would seem to have an inherently stabilizing and moderating effect, and the historical record seems to indicate the same. OTOH, this also implies that deliberative institutions are very important - if a society becomes fractured and distrustful for whatever reason (one can summarize this as "social decay", "decadence" or "dissipation of long-term social capital"), deliberation becomes a lot harder and radicalization has a chance to prevail once again. The proper answer is not authoritarianism of course, but a renewed focus on stable, long-term, social-capital-generating institutions.
Your question is basically "Couldn't Facebook just ask someone else to pay their fine?" – to which the answer is yes, they certainly could. But I highly doubt it'd work. I mean investors would basically be bailing out Facebook and wouldn't get anything in return.

Look at it from the perspective of existing investors: They would be forced to buy the new shares Fb is issuing in order to maintain their respective percentage of shares and, thus, their expected future dividends. There's nothing to gain from that – in fact, their investment's expectation value just goes down as they now need to pay an additional price for the same expected future return. Needless to say, shareholders don't value such a move, so any CEO trying to pull off such a thing would likely be removed immediately.

There is absolutely pressure to go to college, but there is hardly pressure to follow passions. If there was, then the two would be in conflict. The pressure is: don't follow your passions, go to college, major in STEM or "something useful". What has that resulted in? An inflation of watered-down STEM-lite degrees not just from the standard degree factories but accredited state research universities, that provide none of the benefits of a liberal arts education and still leaving one poorly trained to produce.

I am willing to bet that given a population of philosophy majors and a population of engineering majors, if you gave them an equivalent year of quality mentorship in programming, the philosophy majors would perform better. Because philosophy heavily emphasizes critical and abstract thinking. Better yet they might be able to really think about the consequences of the systems they build, whereas the tech industry mostly seems to have no problem and no concerns about building a global surveillance apparatus. Engineers learn how to do now the stuff that is relevant now. As a software engineer I am constantly battling with abstraction, and I constantly feel held back by my limited understanding of math, science, and philosophy.

The cost of college is an issue of its own and it's irrelevant to choice of major. School is the one place where we have an institutionalized system to study and progress the liberal arts as a whole, which teach us how we got here, what we value, and how we ought to live. One episode of The Wire should be sufficient demonstration of the need for our understanding of sociology to improve, among other things. Discouraging any of the liberal arts due to the overwhelming cost of college exacerbates our problems and risks turning universities into trade schools, directionless and with all the volatility of economic cycle.

I guess it depends on how you define a political radical, as a radical is one who stands against the status quo.

Given that current mainstream politics seemingly sees evaluating your own errors as some kind of a weakness, to openly do so right now would be fairly radical for a politician.
I think I got the wrong impression from your article; I thought you were trying to write something like a Gameboy emulator.

As to not being fast enough, smartphones now have multiple >1GHz cores, and emulating an ARM with an ARM naturally leads to virtualisation-ish approaches. It doesn't seem a mid-90s/early 2000s PDA would need that much computing power.

Show HN: Packagr.app – price decrease and security scanning
Hi,

I have recently pushed some updates to my startup, https://www.packagr.app

Packagr is a cloud hosted package repository for Python developers. It integrates seamlessly into your existing CI/CD processes and lets you store and distribute private Python packages with large teams

Firstly, I've added new security scanner functionality - Packagr now automatically scans stored packages for known security vulnerabilities and lists them for all packages under a paid account.

Secondly, I've also reduced pricing in order to improve conversion - paid Packagr accounts now start at £10 per month

Thanks for looking

But on a pi, how accurate is the CPU and gpio speed? On an Arduino mega it's guaranteed to be 68.5ns give or take a tiny amount because that's how long an instruction takes for gpio bitbanging registers. This makes it possible to interface with hardware that requires this precision timing. On a pi even if you're at 700mhz constant clock, caching supposedly will mess up your timings for gpio. On top of that I haven't seen much in what the lowest stable delay is for the pi gpio.
That the US is a wonderful nation that never did any wrong and never helped dictatorships rise to power in it’s decades long fight against the Soviet Union.
In USA (among the social group I grew up around), it seems like it’s mocked unless you’re also wealthy, in my opinion (eg the Starbucks barista who knows Latin). Even with eg Zuckerberg I think it’s mostly unknown that he has some knowledge of these things, or among many considered an eccentricity. Among very high level societal elites or extremely educated people perhaps it’s viewed differently (I would know nothing about this)

I agree. The first paragraph describes "women having the right to vote" as something which was once "the radical fringes of society".

The second paragraph blames radicalism "on a faulty metacognition", and later on that "Dogmatic people manifest a lowered capacity to discriminate between their correct and incorrect decisions".

The referenced paper includes "Radical participants showed less insight into the accuracy of their decisions".

But nowhere does it explain how the radical proponents of the suffragette movement of the 1800s has anything to do with faulty metacognition.
>a radical is one who stands against the status quo.

A radical is someone who is willing to use extreme measures to achieve their political objectives. Nothing to do with the status quo. Totalitarian regimes, for example, usually maintain their status quo with radical zeal and measures.
Gen-ed humanities courses taught to giant lecture halls aren't quite the same as the much smaller courses the majors take. You are extremely likely to be put on the spot and made to defend a subjective position you've taken. They're tough and require you have tons of knowledge at hand to succeed in them. In math, and to some extent engineering or science, you can often reason your way through if you get stuck, or at worse there are often simple procedures you can rote memorize.

I do agree that non-STEM degrees should have stronger math requirements. But K-12 math education in the US is such a disaster that the universities wouldn't stand a chance if they wanted to do it.
Thank you for answering me.

As with doctors, journalism has an aura around it of being populated solely by noble, honest, and impartial folk. Unlike doctors, there's far less-buyin to this mythos from people not working in the industry, but it still exists: think about how many people you know whose "beliefs" consist largely of uncritically repetition of takes from the handful of publications that they have chosen to trust deeply.

In reality, any industry populated by humans (perhaps excluding those with extreme barriers to entry) is going to have people on most points of the spectrums of stupidity/intelligence and honesty/dishonesty. There's no bar that means you have to be particularly smart or intellectually honest to be a journalist.

The upshot of this is that when you see issues that systemically[1] affect an entire industry, you can expect to see this bias to a pretty blatant degree. A banal example is that of Google Reader: its loss was perhaps worth bemoaning, but the sustained hysteria from the media was insane (hilariously, this was around the same time they were pronouncing Google+ as dead, despite it having a multiple of in-stream DAU compared to Google Reader).

So, to finally get to my point: the upheavals that the media industry has been going through the past decade is (fairly) blamed on tech and (perhaps less fairly) personified by large tech companies. That doesn't mean dismissing any criticism of tech, as there are plenty of valid ones, but reading coverage critically is always valuable, and particularly so on topics where they have an incentive (emotional or otherwise) to dissemble.

[1] or even statistically: the claims of both pro-Democrat and pro-corporate bias in large media are IMO exaggerated but are also likely true to at least some degree: they're an unavoidable consequence of the industry being heavily skewed towards people/entities identifying as Democrats working for/being large corporations.

Haven't read it, but based on the table of contents it looks like it has at least two of the very common problems with QM books: (1) starts with continuous degrees of freedom rather than qubits, and (2) talks about observables rather than PVMs.
This isn't surprising since much of what's wrong with how QM is taught has been illuminated by the young field of quantum information, which hardly existed when the book was published in 1992.

Higher speed BCI applications involve risky invasive procedures.

Only Apple gets that kind of "monopolistic, but..." affection here. Everyone else (Google, Facebook, Amazon, Tesla...) get crucified for the same kind of thing, every day.

Of course I don’t agree with the app. But from what I can tell, at least on iOS, the app is just a front end for a website and a set of services. The app itself doesn’t intercept communications on the phone or use any special phone permissions. From another site, I saw the Absher service will notify the husband via SMS.

With NYT’s (usual) shallow technical reporting, I can’t tell what the app does. Just like the article for this post. The only reason we on HN suspect that the apps for this article must be using some combination of MDM API’s and a VPN is because we know how iOS works.

But I can always throw the question back at you. How can you on one hand say that it would be okay if this app did do something similar (which I can’t tell) and Apple banned it for privacy reasons but not okay to ban other software that is spyware?
