> that can track people as they go from one website to another

Note that even in Google Analytics, this requires extra set-up, has limitations, and tends to be pretty fragile in practice. GA identifies users by a first-party cookie and tracking cross-site visits requires decorating links with cookie values.

If you're interested just in aggregate traffic from one of your sites to another, rather than something that requires full-path analysis (like marketing attribute), then you can get that from looking at referrers. This should be more-or-less equally available in GA and server logs.
>If it were up to me, every American would have the time and financial stability

"Time" and "financial stability" is not an absolute measure, but is relative to your level of 'care' about the issue. I don't have 'time' to visit someone I don't care about. I make time to visit someone I do. Someone of modest means who has to work many hours a week and raise kids, won't have time (or 'financial ability') to attend a political rally if they don't really care a lot about it. They WILL make the effort if they did. If they don't care about your political cause, but you go ahead and remove all the perceived barriers, they still won't care, and they will prioritize other things they care about over your political rally or caucus.

That's what you're missing here. You're under the impression that the reason why many people don't attend caucuses is that they aren't able to - that's not reality. As a counter-example, many many many people who have all the free time in the world and all the money in the world, also don't attend caucuses. Why is that?

My favourite quote:

"I hate to say it. It's inevitable that we're going to go onto computers. All the knowledge I've acquired over these 26 years is all kept in a little box now called a computer, and I think probably, most jobs are going to end up the same way.

Do you think computers are a good idea in general?

Oh, there's no doubt about it. They're going to benefit everybody eventually."

It intentionally gamifies financial transactions (see the OP's comment about the colorful confetti that displays when user make trades). The app is designed to provide a dopamine hit when making trades, the only purpose of which is to compel the user to make additional trades.

Robinhood intentionally attempts to make financial transactions fun and desirable to the user. This is to drive more trade volume on their platform. The app is leveraging psychology to make users more active on the platform, which may not necessarily be in the user's longterm financial interest. If your financial app uses the same gamification tricks as a slot machine, that's a problem.

This person was 20 years old -- their brain isn't even fully developed yet. No responsible company would allow a 20-year-olds to dig themselves into a $700,000+ hole. That's a lifetime of debt for all but the highest income earners. Even banks, for all their issues, wouldn't allow that.

Yes, the person was legally an adult and make their own decisions. But no responsible company would facilitate a chain of decisions that would lead to $700,000 in debt. If only for self preservation, because the dead can't pay off that debt to the company.

But hey, Robinhood is playing with fake VC money so whatever... right? What's a couple of bodies when Robinhood is a disruptor and makes complex financial transactions fuuuuuuuuuun. Party on!

More or less. It really depends on what your code does and how frequently in calls into C modules such as Numpy. The Python side is JIT-able while the C side is not. PyPy3 currently implements Python 3.6.9 so you'll be missing out on any 3.7+ features (e.g., built-in dataclasses but a backport is available from PyPI).
That's not true at all. Plenty of developers sell through the Epic Store (having development funded by Epic), or GOG, or the Humble store, or on Itch.io, or even via microsoft store. There are abundant ways to fund a project on PC precisely because it isn't a walled garden. Sure Steam has massive dominance, but that is arguably because of the relatively open nature of steam itself. Valve don't have or seek a monopoly on distribution.
Agreed. I've seen this in the US and Canada, but in places that were 1) very bourgeoisie, very white, and pseudo-leftist, and 2) near a university of some sort.

Either way, I'm glad this letter exists, as it validates my priors :)

Well that’s a different story then. It sounds like you measure things your own way, so I agree that analytics are pointless in your edge case.

For us, we have generated a lot of revenue by measuring what works and what doesn’t. That’s why analytics are worth it for a lot of people.
This is precisely the problem I have with how one is supposed to approach looking for product-market fit in a startup: contact customers and ask "would you pay for this? how much? if not, what would make it so you'd pay for it?" I don't feel like that's a good way to find things for customers to buy, but it's the advice from the VCs.

Is It too soon to talk about the C implementation?
Couple of points:

0. You offer an interesting idea: providing days off that individuals can take off for whichever reason they want. Seems like a good policy. This could be implemented as a 'mandatory minimum number of days off for every full time worker'. It does not have to compete with national holidays.

1. I think holidays serve a symbolic meaning too: indicating what we as a nation value, even if not every person in the nation does. It's like an agenda: we choose to remember certain individuals or ideas. Some like Columbus day, people are fighting and trying to remove.

2. Holidays provide a day when "everyone" (obviously not everyone, but most people) are reliably free without work. This makes family gatherings easier (4th of July). I think it's a tragedy that election day is not a national holiday.

GoatCounter author here: yeah, that's not perfect; this also came up in the HN discussion for the article a while ago[1]. I've been in touch with one of the authors of the EUPL since and the short of it is that they don't really think it's an issue.

I've thought about this for quite some time, and decided I'll use a slightly modified version of the EUPL which removes GPL from the compatible license appendix. Just haven't gotten around to that for no reason in particular.

With sigaction handlers (as opposed to the C standard library's simplistic signal handlers) it's not just exceptions, it's more general, like a condition system like in Common Lisp. From inside the handler you can analyze what's wrong, then manipulate the program state and then restart the computation where you were, or at the next instruction, or wherever else you choose. In contrast, your typical exception mechanism (as in Python or C++ or Java or whatever) will unwind the stack and make it impossible to restart from the exact place where the problem occurred.

Individual corporate humanism isn't a crime.
I would find that a very fulfilling and meaningful project, personally. I'd actually consider it way more fulfilling than working on the core product, which likely mostly involves trying to think of and implement clever ways to expose users to ads and sponsored content, and otherwise try to directly and indirectly monetize users.

Here, the goal is to prevent phishers, fraudsters, scammers, spammers, catfish, impersonators, malware spreaders, etc. from running amok in a somewhat unprecedented way by tricking users en masse into thinking they're really receiving photos/videos in real-time, using automated tooling. My understanding is this heavy degree of obfuscation (combined with other anti-tampering tactics) has gone a very long way to mitigate a huge amount of abuse.

From talking to people who've tried to bypass these mechanisms to do unauthorized and potentially risky things (like send things from a custom client in a way that could allow for mass automation), they describe this as an essentially intractable hurdle from their perspective. Of course, it isn't in actuality, but it is for most people when compared to lots of other social media apps, and I expect Snap to change things around not long after OP releases part 2. Cat-and-mouse never ends.

Ask HN: What are good resources to learn about protein simulation?
Hi,

I am wondering if anyone has recommendations on resources to learn how to simulate proteins.

I was having the most interesting conversation about proteins with a friend who is doing her PHD in antibiotics. She told me she had to run a protein simulation, and how her professor sent it over to some lab with super computers. so definitely interested in learning what the state of the art is with regards to these simulations.

I've done ~4 years of Physics modeling so I am familiar with how simulation in the engineering world works.

I've done cursory googling and found some books - but looking for recommendations before I make a purchase.

I recommend having a look at "Practical Electronics for Inventors" by Paul Scherz and Simon Monk. The book offers a very good introduction about the basics of electricity with many helpful illustrations, written in a down-to-earth style. In case you are interested in electronics, you will find that the book covers many intermediate/advanced topics such as operational amplifiers with lots of practical examples.

>I strongly disagree with anyone who denies that the trade-off exists.

Well of course the trade-off exists. I never said it doesn't take effort to go out and caucus. It does. Having said that, there are many people with the time and means to attend a caucus (as you would define it), still don't attend a political caucus. Why is that? I'll tell you: because they don't care about caucusing and therefore the trade-off for them (as minuscule as it is) is too big.

So you aren't making any profound argument. What you're missing is the other side of the equation - it isn't just about the relative effort to do something, but more importantly the level of care that people have for that something. That is if people don't care about attending a political rally, they won't attend a political rally even if you remove every barrier you perceive there to be. We see it in elections all the time. For all the talk about structural barriers to voting, black turn out was a record high for Obama because black communities really cared about voting for Obama. Black turnout was not as high for Hillary, because she didn't have the same level of support from the black population.

When people care about something, they will find a way to engage.

Ask HN: Better language than C for playing with pointers
In over 20 years of software development, I've only worked with languages that don't use pointers. Each time I delve into pointers in C, I run into problems referencing and de-referencing, passing them around, etc. I understand pointers well enough. I've read countless tutorials and really do understand them at the machine level.

Can anyone recommend a language other than C that uses pointers, so that I might understand actual manipulation better? I'm not interested in a discussion of why they are bad and how we should use Rust. This is purely for my own education to get past this weird block I seem to have when I try to use them in real applications.
Couple of book recommendations if you find mountaineering and its associated safety culture interesting:

Forever on the Mountain is a pretty in-depth reporting of a spectacularly deadly mountaineering disaster on Denali (or McKinley), which Ed Viesturs has climbed ~200 times per the article. I know it's easy to say with the benefit of knowing how it ends, but you can just watch the mistakes pile up.

From TFA:

"These high-altitude mountains are one of the few places on the planet where there is literally no help. If you screw up and break a leg, it’s up to your partner to get you down."

Touching the Void recounts an accident in which this was exactly the case. The author broke his leg on the way down at altitude, and things got (much) worse from there. Spoiler alert, he survived to write the book. Pick a time when you can finish it in one sitting. Once you get about 1/3 of the way in, you likely won't be able to put it down.

Everest the Hard Way is a telling of a successful Everest expedition, but provides a good look into the planning and decision making that makes that happen.

Deep Survival is also worth a read. It doesn't focus exclusively on mountaineering, but as I recall, some of the case-studies are mountaineering. Sorry, it's been a while.

Into Thin Air, from which the article riffs on the title, covers the 1996 Everest disaster. It's been even longer since I read that, but it's worth a read.

I'd be interested in a book recommendation if anybody has one that talks about how safety culture is spread. I'm a rock climber (as distinct from mountaineering), and one of the things I observe is that the safety culture in the sport sucks [0], [1]. I'd be curious what the climbing community can do to better spread or develop a safety culture within the rapidly growing sport, especially as fewer people are being brought in by experienced mentors and are instead getting into it via rock gyms.

My admittedly outside understanding is that mountaineering has a much more developed and widespread safety culture, perhaps because the barriers to entry almost require getting into the sport via a mentor.

[0] I saw somebody (top rope) belaying outside while lying in a hammock. This was on a single pitch route with ample space to stand. Even if you have to be anchored, there's just no reason to impede your hand and arm mobility like that.

[1] A representative for a major gear manufacturer (if you climb, you've heard of them) was explaining a new safety feature on a new model of their belay device. He was telling me about it and started giving an example of where it would be valuable by saying something along the lines of "suppose you were climbing and your belayer didn't know what they were doing".

It's telling and disappointing that a major gear manufacturer seems to have accepted that the safety culture in the sport has allowed this scenario to be plausible and/or common.
What issue do you have with the contact tracing application now that it’s switching to the Apple-Google model?
> Can be picked up by almost anyone

There are lots of solutions that fit your criteria, including this one.

The problem is that none of them will be quick. The surface area for non-trivial app development is massive.

That said, a single-language, full-stack option that uses TypeScript would be the quickest to learn (mostly because of compiler rules serving as guard rails and because it's only one language).

I have no idea what the state of full-stack JS is right now because I'd never use a full-stack framework (or any framework).

Everything we know about Tom Cruise’s plans to film a movie in space
The drawback of a centralized, government controlled /TRACKING/ app is the MASSIVE AMOUNT trust it requires not to be abused. Neither now nor in the future. Purely scientifically it's quite useful in the current situation, much more than the decentralized approach we're using here in Germany; I think that goes without saying. But creating such a precedence for mass surveillance in our democracies is extremely troublesome, and -m-i-g-h-t- will cause a lot of harm in the long run.

Also, only speaking for myself here: The morning the German App was released, I installed it without hesitation or any trace of doubt. It's now running on my [only] phone, which I have 24/7 with me. So within its limits, the App is rather effective. If it was centralized,... I probably would have hesitated a lot, maybe even skipped it or installed it on my old phone (with the GPS disabled via root), and only turn on that phone on demand.
What I want to say: Acceptance/wide-spread use is rather important. Of course the gov can [try to] mandate the app to be used (does the UK do that? idk), but then they're opening another can of worms because they're discriminating against poorer people/demographics who might have older phones with poor battery, limited memory/RAM/CPU, or no smartphones at all (e.g. cheap dumbphones).

Full disclosure: I'm sometimes checking with BeaconScope if the people around me are generally using the app. It's not as many as one would like, but it's slowly ramping up.
Based on that description of Pijul, it does seem to be a semilattice: it has a merge operation that's associative and commutative, and while it doesn't explicitly state that it's idempotent it's hard to imagine merging two states and getting anything else back than the same state.

Not super familiar with Pijul though!
