Ask HN: Cheapest way to host a real-time Covid appointment finder website
Building something similar to https://impftermin.berlin/.

This site does 400K hits monthly, (using a polling interface every 5s to an API).

The functionality is:

- Scrape Doctolib, KV Berlin on an interval for appointment slots

- Show appointment slots on website

- Push updates to users in real-time

The full (un-optimized) scraped dataset of appointments is 1.5MB.

What hosting providers (vercel, render, ec2, etc.), programming languages (node, rust, go, etc.), hosting strategy (ssr, static page, spa), transport ( websockets, server-sent events, polling), frameworks (next.js, blitz, hasura, etc.) would suit this task the best?

I want to host it as cheap as possible.

Low development/maintenance effort is also important.
Connecting your critical equipment to the internet is never a good idea. And if you don't connect it to the internet, the support status of the OS it runs shouldn't really matter much.
The most expensive coffee making gadget in my house (and I’m not going to count them) is the standard drip machine which most people have (around here). The other stuff (e.g moka, french press, aeropress) which coffee enthusiasts prefer, are way cheaper.
Curious to know what you would recommend sub $500.
A long time ago when I had younger ears, I heard these at an audio show in London, in a "sound proof room" and I will never forget the experience. I was working for TagMclaren at the time, having just left dCS Audio and I thought I had heard a lot of high end speakers by then, but these blew my socks off and left a lasting impression.

I half believe it was the presentation - dramatic, but also extremely clever choice of SACD source content with some theatre thrown in for good measure. However, that 12 minutes in a room in conference hall in London with the Nautilus speakers was something I will never forget for a "this is what money buys you" experience. Warm, huge dynamic range, concert hall experience - comfy chair and dim lights helped as well :)

At Tag, we built the "tag mclaren speakers f1" that had a lot of elements I feel borrowed from the B&W industrial design (but made F1 grade) - I used these daily for several years, but was never able to convince myself they were as good as that one time experience.
Interesting. Kinda weird that they don't see more growth, they do have a pretty compelling "serverless Kafka" cloud offering for those cases where Kafka shines, but where the ops overhead of running your own is a bit too much, which should cover quite a lot of real-world cases. IIRC last time we checked they weren't able to offer Confluent Cloud under fully GDPR-compliant terms, so we had to pass, but otherwise we were pretty impressed, especially considering the pretty attractive pricing at the time.

Dell docking stations like the PR02X provide serial/parallel ports directly from the laptop, and Dell Latitude laptops with the E-Port docking connector were made until ~2016.

Both the PR02X and Latitude laptops with an E-Port are readily available on eBay for reasonable prices.

This is not at all my area of expertise or anything even remotely close to it but this seems to be a very similar sounding story to one of the core underpinnings of Fuschia.

My understanding was that they put everything kind of dangerous into the micro-kernel and then built their security model around ensuring that everything that interacted with it was only using a set of primitives that they could "guarantee" to be "safe".

Could someone who actually knows about this kind of thing let me know if I am even roughly in the ballpark of correct here?
What kind of bugs me is that there really aren't any kits and very few DIY designs that match the kind of speakers I really miss, at least not ones focused on home audio.

Those speakers being the old-school big boxes with 12-15" woofers, sometimes multiple and usually 3-way designs, sometimes 4-way. Large, heavy, imposing and punchy, big speakers for big music. I know modern speaker drivers have come a long way, but you just can't get that from 6" or 8" drivers in the same way.

DIY PA speaker designs do provide some of this, but I'll have to tweak the aesthetics more in a "living room-friendly" direction, because nobody seems to want big beefy speakers anymore.
Is pretty common for people to assume that passing a law will just make things go away. As you point out, the real world doesn't work that way.
ah, the koppelcode needs to be manually entered, but then the next step is to scan a QR-code (Android, latest app version, but it's been like that for a long time afaik)

I do wonder why that code has to be manual and not embedded into the QR code, I assume there's some reason for it. But it's also only four letters, not terribly tedious.

These kind of headlines are so terrible. This is like saying UPS launches new server because they delivered it. SpaceX is literally a transportation company. The title is nothing other then trying to clickbait of the popularity of SpaceX.

They are a bit underpowered, rumble with Bluetooth, and you need to turn the bass and highs quite a bit down to make them sound flat, but I bet that something like 100x times more expensive studio speakers will be the cheapest setup that matches them in the clarity.
I suppose you don't hear often about all the market/advertising companies buying each other. Even though I work in this field, I am almost always clueless about who are these companies.

I'm a great fan of progressive web apps (PWAs). However, last time developing a PWA, the support by Apple’s Safari browser was not yet sufficient. For example, you couldn't add an app shortcut to the home screen on iOS.

So today you can choose between the devil and the deep blue sea: Choose a PWA and get destroyed by Apple: bad support by Safari; or choose a mobile app and get destroyed by Google: arbitrary decisions in Google Play.

I have worked as a barista before, and also a pretty much life-long coffee drinker and lover, just a little bit of a snob and a seeker of quality.

I know more than 20 different ways of making coffee.

Here is the best coffee brewing method I've come up with.

First, I get some CLEAN water, and I boil it in an unfinished metal or ceramic-finished metal pot. I use a regular pot so that I can see inside. I also like to let a little bit of the water evaporate...

While it's getting ready, I get the best and freshest coffee grounds I can muster, it's better if I can grind them on the spot, but that's not always available.

I put the coffee grounds, as much as I think is necessary, into a glass or ceramic bowl, and pour the boiling water over them. I optionally cover and/or stir and let steep.

After about 5-15 minutes, I pour the coffee into another glass or ceramic bowl, letting the grounds stay at the bottom of the first bowl.

The coffee is now ready for drinking. To keep it warm, I cover it and leave it in the oven for insulation, or use an electric plate. It usually doesn't last long. It's good cold too.

The second best method I know is cold-brewing in a similar fashion, takes a number of hours I haven't tracked yet.

If anyone is interested in learning why this method is better than all the others, please reply with the method you think is better and I will explain why you're wrong. :^)

Edit: The method in the video is quite good, and my only complaint is that it uses disposable filters, which leads to unnecessary materials harvesting, human labor, biome squeeze, diesel use, waste output, and other artifacts of production.

It's conceivable that microcontrollers with memory management units could become more commonplace. Your memory-trashing program could be restarted while the device keeps on doing other things, rather than the traditional bare-metal approach of having a watchdog restart the device.

I visited a castle in Switzerland (Chateau de Chillon) and they had a presentation on medieval eating and drinking habits.

Everything is bloated.

You need 3GB RAM to open some web pages in your browser nowadays and that's insane.
Even the API we see in the tutorial is, well, problematic:

s1.energize(s2) has the s1 entity transfer energy to the s2 entity ... except that if s2 == s1 (or s2 === s1), s1 tries to harvest energy from somewhere.

... that would not pass my code review.

a) It's a PR stunt. Adding *in space* works a lot better than "SpaceX is running an Ethereum node" alone.

a.1) Particularly for the company "SpaceChain" that actually runs it, ridding piggy back PR on the name of SpaceX and the recent Tesla/Bitcoin craze.

b) Every time Elon Musk appears in a sentence together with crypto currencies, prices bounce around (exactly what you want in a currency, right). This can be used deliberately to make bank and in contrast to the stock market, there is no regulatory body stopping/punishing that.

c) Last time I checked, the ISS didn't have a diesel generator standing out back, so it will run on solar power only (which is of course offset by burning rocket fuel to get there in the first place, and probably by burning itself up when eventually returning home)
They certainly don't have equivalent intentions or outcomes. So no, they're not equivalent at all, no matter how hard you try to justify and whitewash one-sided Republican bigotry by claiming to know everyone's true motivations. You're still making a false equivalence.

Then name some openly gay Republicans in power, and tell me what they've done to tangibly improve LGBT lives. (Who didn't switch to the Democratic party after coming out, like Charlie Crist, and who don't deny it, like Larry Craig or Lindsey Graham.)

I have never had a cup of coffee in my life.

The comments are hilarious to me though, like everyone is speaking a different language.
An acceptable roaster costs $20 (air popper), acceptable grinder $30 (hario or equiv), and a good espresso maker costs $30 (aeropress). And a good set of headphones costs $50 (ATH m20x)

I spend far more on beans annually than I have on hardware in the past 5 years. I have zero interest in chasing more expensive hardware for a fix. But I did actually upgrade my headphones to Sennheiser hd599 when the aux cable in my old pair broke.
Floats were never a 'hack'. There were hacks that used floats to achieve layouts they weren't intended for. But the flowing of text around a floated element was a required tool that floats enabled.
"Lisp is still #1 for key algorithmic techniques, such as recursion and condescension," — Verity Stob.

So it seems that when the runtime environment has rather restricted opportunities for recursion, the LISP variants double down on condescension.

P.S. And I don't mean it to be a criticism, reading the description of the primitives was rather enjoyable.
The question ought not be if we should legalize these drugs (with obvious proven medical use) but rather, why were they criminalized in the first place?

"Legalize" implies we need permission from the government to control what we put into our own bodies. That doesn't really make sense in a free country.

"Decriminalize" makes more sense: it rightfully implies the government screwed up when it outlawed the substance(s) in the first place...

IMHO banning chemicals is

a) impossible from a practical level because there are infinite chemicals and no means to enforce their use

b) misguided since politicians are unqualified to assess the various technical aspects of medicinal chemistry

c) counterproductive because when something people use is banned, they turn into criminals and the end result is a black market which encourages people to ignore other laws which actually DO matter (like when folks commit murder related to drug deals -- if the drug were not criminalized, then there would be no need for a black market drug deal)

TLDR: Don't legalize it. Decriminalize it!

Space has different risk factors than places on earth, so this diversifies the risks of the ETH network by adding another dimension of geographic decentralization.

Why the ISS -> probably because it has a well-understood power, data & thermal framework that the company now doesn't have to build for themselves, nor do they now have to manage the orbit of their node.

> So hardware manufacturers get the hard choice of either going for the general market that expects things to work or going for a tiny market that is happy with some of the most popular services not working by design.

Software is already here, particularly in social media (mastodon/SSB vs Facebook). That hardware eventually gets there seems to me an inevitability (arguably we're already at least partially there, as evidenced by the fact Purism/Pine64/etc exist).

I still don't see it as a problem, though, because an individual can have different technical interfaces (devices, OSes, etc) for different purposes.

Generally, I put my personal stuff on systems I understand/control.

For some things, like watching TV, I'm okay with going to Netflix because that transaction is expected to be transitory. If Netflix disappears or declares themselves a new world order tomorrow, I can simply unsub and no harm done.

Where things get problematic is when so much of someone's life is wrapped up in a mono-corporate cocoon (e.g. Amazon shipping things to your house and running your servers, or Google serving you search results + mail + maps).
A minor nitpick: the Aeropress makes great coffee (I have one in the cupboard myself) but it definitely doesn't make espresso.

Are you maybe conflating transgender demands vs gay rights?

There is definitely opposition to "gender is what you identify with and not something objective", which I think it's reasonable - there are biologically 2 genders (not including extra chromosome anomalies).

At the same time, everyone is free to believe and say what they want and noone is trying to change that.
The main opposition is around compelling speech according to someone preference not to trigger them or allowing parents to inject hormones in underage kids.
Nice! From the perspective of discovering and addressing the needs of customers, imagine one could simulate the ecosystem via a population of customers and other context attributes and evolve the ecosystem forward in time, one would be able to observe and measure the outcomes … As for a standard definition of value, there might not be one since it is context dependent … fundamentally, just like “beauty”, value is in the eyes of its beholder :-).

In English you mean.

In Portuguese the name is still customarily "Pequim". To illustrate, go to the Beijing page in English Wikipedia and change it to Portuguese. Check what's the title of the page.

That's also the canonical name used in French, Finnish, Italian, German, Spanish, Swedish, and many more. Last time I checked they're all western languages.

Names are chosen by the users. It's not because the English-speaking word was quicker to adopt the new name that it suddenly became "universal". Universal in English? Sure.

I'm sure that eventually most languages will switch to their local spelling of "Beijing", but that is many decades away. You can't change a word that has been used for centuries by decree. Languages don't work that way. Or maybe for English it does, not so much for many others.
