I see this as a good thing. It means that we'll (hopefully) get stricter security revolving around using these numbers. It'll no longer be enough just to yap out a 10 digit number to "verify" you are who you say you are. We already have a (albeit heavily critiqued) national 2FA system in place (MitID).

We'll have to start treating the CPR number as just a username, instead of a password. It should never have been "secret" in the first place.

This bell would be illegal in Denmark, where our laws clearly state that you are only allowed one signal giving device and that any signal giving devices attached to vehicles (including bikes) can only produce one constant sound.

How this would be enforced is a different topic.

I wrote both my master thesis and PhD on Hoare's Communicating Sequential Processes. I really enjoyed it's simplicity, expandability, and was always amazed that it inspired and influenced language constructs in Go, Erlang, occam and the likes.

They were never concurrent, they were communicating. https://en.wikipedia.org/wiki/Communicating_sequential_proce...

The DKK5499 is with VAT. If I enter a San Francisco zip code, it still only comes out to about USD654.

Ugh. Why is is so much more expensive in Denmark? Here it's DKK5499 for the 256 GB version. That's USD857.

Ask HN: Has anybody moved their local community off of Facebook groups?

madsohm — Mon, 02 Feb 2026 08:57:41 +0000

Facebook's feed is nonfunctional. Only some people get notification, even though they have notification for all messages turned on. Only some get the newest posts in their main feed. Sometimes I do get notifications, but only long after an urgent message was posted.

Has anybody successfully moved their local community off of Facebook groups?

I'm thinking about neighbor conversations/events, daycare, kindergarten, kids' classmates, sporting communities, etc.

If so, where did you go? Did you build something yourself or do you self-host some open source project? Did you find a good paid alternative?

New comment by madsohm in "Show HN: I built a Ruby gem that handles memoization with a ttl"

madsohm — Tue, 22 Apr 2025 19:27:18 +0000

Since using `def` to create a method returns a symbol with the method name, you can do something like this too:

  memoize def expensive_calculation(arg)
    @calculation_count += 1
    arg * 2
  end, ttl: 10, max_size: 2

  memoize def nil_returning_method
    @calculation_count += 1
    nil
  end

I find that a lot of their "fully remote" positions are only remote if you live in the US.

I was always told that the best position is always the next position.

It's like the Monty Hall problem, switching is always the better solution.

New comment by madsohm in "Ask HN: What apps have you created for your own use?"

madsohm — Wed, 13 Dec 2023 10:29:00 +0000

I did the same for both of our kids. For the first, I created a web app where you could +1 or -1 on all legal names. I even used the Web Speech API to read aloud the names, if you clicked them.

For the second kid, I created an iOS app using React Native (https://i.imgur.com/aaTqXAY_d.webp?maxwidth=760&fidelity=gra...) where you could swipe names Tinder-style.

We didn't use the apps to find _the_ names, but to get a narrowed down list we could pick from. The projects were fun and educational.

Many languages also support a comma after the last item, meaning you can still have one line diffs and have a sane reading structure:

    [
      item1,
      item2,
      item3,
      item4,
    ]

In Denmark we use 24h, but we call them by their 12h equivalent, e.g. "15:15" is "a quarter past three". However, you could also say: "It's now 21 30" to signify half past nine. Or some people would say: "It's half 10". Okay, having 24h clocks don't make it easier it seems.
