You're totally right. Although in my experience this is much easier to maintain with "upstream root certificates" (not sure how you'd call them) then self-signed certs. Applications like Home Assistant are already TLS aware and simply trust all root certs which are available on the host. With self signed certs, you have to distribute them all by yourself.

Besides this trade-off, you have to check all clients to be TLS aware on beforehand. In my setup, all clients were capable of TLS. The only hassle are my NodeMCU devices which need to swap the WifiClient to a WifiSSLClient and you need to embed the public DST Root CA X3 yourselves.
Right, I would need some strong evidence to believe that actually happened in this case. In the linked case it was a VERY low value stock aka Penny Stock, aka OTC (over the counter, as opposed to a listed stock as in listed on a stock exchange), and the SEC DID take action against the guy. In the case of listed stocks, there is a lot more attention and regulation built into the system.
To be honest, this sounds like "stoned-ape theory" tier speculation without evidence, so it's good that it's being downvoted. This sort of thing is honestly super annoying. You like to use mushrooms recreationally? Great, do what you want. But when people who are excited about psychedelics start doing this thing that you're doing above, namely trying to say that ancient use of psychedelics was the reason for all manner of cultural practices, it's very annoying, anti-intellectual, it it has honestly soured my opinion of psychedelic-users. For example, it's really hard to take you comment seriously when it contains things like:

> Various accounts describe the shaman and the rituals performed in ways that are fascinatingly similar to the narrative of Santa. An all-knowing man who defies space and time? Flying reindeer? Reindeer-drawn sleds? Climbing down the chimney? The giving of gifts? The tales of the Sami shamans have it all.

> This partially explains the practice of the Christmas tree, and the placement of bright red-and-white presents underneath, which look like Amanita mushrooms, he wrote.

Yeah, except these aspects of Christmas described here are largely American traditions with well documented origins. So even if some (tenuous) parallels between Sami folk religions and modern American Christmas exist, how exactly is it being postulated that those Sami traditions made their way into the US? Scandinavian immigration to the US was quite small in comparison to German, Italian, Irish, etc., and they were rarely ethnically Sami. Meanwhile, as I've said, US Christmas traditions like Santa, Christmas trees, gift giving, the Christmas color scheme and so on have pretty well-identified origins, which are largely from British and Central European traditions, with a modern, more secular, reinterpretation coming about in the 19th and 20th century.

Look, I used psychedelics in my younger days. They have many effects, but the strongest one I would say is that they make you think things are far more profound than they really are. I don't doubt that they have potential for treating depression or addiction (recent research on this seems promising), but it seems that far too often, psychedelic-enthusiasts fall into the trap of "psychedelics are so cool, I must find a way to tie each and every thing to them."
US is doing no such things and Germans are far more racist than Americans it’s not even close.
Well you're still flawed if you scale your argument. What if you take your argument, and scaled it up. What if you promised each kid 1 trillion burgers. Will you have access to 1 trillion burgers tomorrow? What if they take their future 1 trillion burgers and sell half. What if you walk into McDonalds to claim the 1 trillion burgers. Does McDonalds have 1 trillion burgers? No.

So you're saying it's okay to promise burgers as long as it's an amount that actually exists and McDonald's can fulfil it. So what you're saying is that you shouldn't sell things you can't possibly fulfil? Hence the argument against this kind of trading.

I'm firmly of the belief that if there is genuine social interaction to be had, it will be had for the most part.

Forcing social interaction (corporate mandated fun) is just another tool to tie employees to an employer to make it more difficult/less desirable for them to leave for better opportunities.
Some observational studies have shown a slight correlation between subject reported saturated fat intake and heart disease. However those studies had multiple confounding factors (healthy subject bias), the effect size was small, and no one has ever shown clear causation. I'm not recommending consuming extra saturated fat but don't overstate the strength of the scientific evidence.

The real issue with heart disease is more about atherogenic lipoproteins than cholesterol, and genetics are a more important risk factor than diet.

Ask HN: How do you test and develop time-dependent/flow-dependent applications?
Hi all,

I find myself running into difficulties when testing and developing for time-depdendent applications. What I mean by that is that certain actions in the flow of command result in states that depend on previous interactions.

For example, how does Uber test their driver dispatch system, and corresponding notifications on the part of users when the driver is getting close to their pickup location? In here, the behavior of the application depends on the driver accepting a request, starting his ride, etc.

I find it difficult to reproduce situations where the previous 'flow' affects the current state of the application and it's expected behavior.

Hope I was able to explain my difficulties clearly.

Thank you!

I can't claim to know the details, but my understanding is that the interaction of linear typing with dependent types is an open research problem (see the quantitative type theory papers, for example). It's also a burden on the user rather than the runtime, so it's a tradeoff.
Lean has an array type, which the docs say is implemented much like a C++ vector or Rust Vec. But data types in functional programming languages all expose an immutable interface, so what happens when someone changes the list in two different ways? Is a new copy of the array made, is some variant of a persistent array used, or does the program just fail to compile?

> so a text file format ought not to unless it is aiming at being something more than what text does.

Gemini does aim at being more than text[0]:

> The "first class" application of Gemini is human consumption of predominantly written material - to facilitate something like gopherspace, or like "reasonable webspace" (e.g. something which is comfortably usable in Lynx or Dillo). But, just like HTTP can be, and is, used for much, much more than serving HTML, Gemini should be able to be used for as many other purposes as possible without compromising the simplicity and privacy criteria above. This means taking into account possible applications built around non-text files and non-human clients.

Lots of documents and books contain passages in other languages, it's reasonably common -- I don't get why people are saying this is a niche concern. Books get around that problem because they have controls around presentation, and they're not designed to be consumed visually, not as a semantic, parseable format. But Gemini, at least in theory, is designed to be parseable.

The predictions did not come true, obviously. A very gradual increase in temperatures is something people will adapt to and is not an emergency.
The city paying for the cameras doesn't give them the right to the footage whenever they want.

The footage is still private and they have no easier access system. Instead, the value is (1) I'm required to have at least two days of 24/7 recording history on the cameras and (2) they now know where these cameras are and the direction that face.

Thus, if a crime happens, they can come subpoena the footage. Simply knowing that there might be footage that could help solve a crime is super helpful to the police. But they don't get automatic access or anything of the sort.
Personally I would love to switch to OSS tomorrow, but I still see many showstoppers:

- Desktop: Linux vs. Windows - worse support for gaming (e.g. anti-cheat), no support for major creative software like Photoshop/Affinity or Ableton/FL Studio

- Mobile: FOSS Android distro vs. Google Android - no guarantee that apps I currently use will work without Gapps, no paid apps or in-app purchases

I have really been thinking a lot about this in the past months, because I would like to improve my privacy. The only real play seems to be moving to Apple's ecosystem, and buying a console for the games (and paying a lot more and losing customizability and repairability in the process).

I run it to communicate with much more applications. It just depends on your own preferences. For example, some tools provide an API (local or cloud based) and you can directly plug in into that API. In The Netherlands you can read your electricity meter yourself by a "Dutch Smart Meter Readings" and DSMR integrates into Home Assistant with MQTT. I use Z-Wave as wireless mesh technology for lights and switches, the Z-Wave controller integrates into Home Assistant with MQTT.

MQTT is so easy to setup and configure, you can use it for any messaging you want. As an example, I run Home Assistant locally to run my home automations, but also check the status of my local devices and online servers (Digital Ocean droplets). One use case is my backup script which publishes the backup results to an online MQTT server, my Home Assistant checks the topics at that server to display backup stats locally. If something went wrong, Home Assistant notifies my directly. PS. The backup script also sends out e-mails which I filter in Fastmail, the success mails are trashed and only error messages are kept in the inbox ;)

His conclusion that minorities are more likely to experience police use-of-force is well-supported.
In my experience MQTT works well for telemetry and one-way messaging, but it's not good at doing request-response flow like you typically do in an application using HTTP. You can certainly come up with a mechanism for doing that, but you're having to re-invent a lot of what HTTP already solves.
Waveshare has one. Haven't used it personally but it seems to suit your needs. Though at ~$50 you're probably better off just getting a Pi 4B + PoE hat.

> Worth noting even its creators say JCL is the worst language ever invented.

I don't dispute that, but I'd kinda like to hear the specifics of their reasoning.

I've never actually used JCL, but I'm willing to cut it a little slack because, IIRC, it literally started in the 60s as a way to specify job-execution information on a punched cards for batch processing systems that had as little as 8K of memory. What I've read about very early personal computers with similar amounts of memory makes me think it requires serious compromises to implement anything that actually works on such a system.

Partial indexes can flip query plans if the covered part becomes so small that it won't be represented when sampled by the stats collector. The planner could then decide that the index scan isn't worth it and could try an alternative less efficient index if one exists.

I’m not on WSB, so maybe I haven’t seen a discussion of this. But I have been wondering why Citadel bailed out Melvin. I can think of a few scenarios:

A) Charity (haha)

B) Lose this money now to prevent losing even more money later on

C) Make a huge return on the equity stake/loan/whatever-it-was-Citadel-got

Maybe it’s irrelevant, but it’s been something I haven’t quite figured out.
Maybe a way to keep track of your guesses would make it more fun. You could also build a leaderboard on the best guessers overall.
Formal Interview Training
Spacelift | Remote | Europe | Full-time | Mid-Senior Software Engineer | $50-120k

Stack: Go, AWS, PostgreSQL, Terraform, IaC, React, GraphQL

We’re a VC-funded startup building an automation platform for Infrastructure-as-Code, adding a Policy-as-Code layer above it, in order to make IaC usable in bigger companies, where you have to take care of state consistency, selective permissions, a usable git flow, etc. We also try to understand the managed resources as part of our meta-abstractions, in order to provide insights to our customers.

On the backend we’re using 100% Go with AWS primitives. We’re looking for backend developers who like doing DevOps’y stuff sometimes (because in a way it’s the spirit of our company), or have experience with the cloud native ecosystem. Ideally you’d have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, or SaltStack.

We’re also looking for a Solutions Engineer (this role is also available candidates in the US, as most of our clients are there), who would be helping customers with working with Spacelift, Terraform and Pulumi. You would also be creating various public content: guides, blog posts, demos, etc.

Overall we have a deeply technical product, trying to build something customers love to use, and already have multiple happy and satisfied clients.

We promise interesting work, the ability to open source parts of the project which don’t give us a business advantage, as well as sane working hours. We’ve got investment days on fridays, when you can work on anything you want, as long as it could possibly benefit Spacelift in some way.

If that sounds like fun to you, email me at kubam at spacelift dot io!
