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.
I think it's 8 Harry Potter and 3 Fantastic Beasts films.
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.
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.

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,...
AI slop - or worse, somebody trying to hide something.
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 hold a PhD in computer science. I have more than 10 years of experience with Ruby and Ruby on Rails. I've helped build and scale frontends, backends, and APIs in general. I'm ready for whatever you throw at me - and can easily learn new technologies and languages, if needed.
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.

PhD in computer science. More than a decade experience with full-stack development using Ruby on Rails. Ex-Elastic, ex-Shopify. Looking for senior/staff engineer positions.
Just learned about 'git absorb' couple of weeks ago and have used it every day since. Amazing tool.
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.
Do note that, specifically in Denmark, you can do a 4+4, where you do a 4 year bachelor/master and a 4 year PhD, instead of the regular 3 year bachelor, 2 year master and then 3 year PhD. Here you'd have to apply for the PhD well before entering the university, or at least whist doing the bachelor studies.
I've donated plasma a couple of times. The machine they use to separate the plasma from your blood cells will give you your blood back. They mix in a non-coagulating agent. This can give a tingeling feeling in your lips, that is best alleviated by eating chocolate or drinking chocolate milk.
I got bored after maybe question 20 and got an IQ of 100 back.
As part of my PhD I created a CSP implementation in Ruby:

Hi HN. I'm Mads.
I did my PhD working on Bohrium (https://github.com/bh107/bohrium). Bohrium is a framework that sits on top NumPy and intercepts all calls. When you have a side-effect in your Python code, Bohrium will take over and JIT-compile an OpenCL kernel, so your NumPy can run on your GPU. This is all done automatically, so all you need to change is `import numpy as np` to `import bohrium as np`. For Bohrium I also created a Ruby frontend, so you can use custom `BhArray` to JIT-compile OpenCL kernels from Ruby code, run when you have a side-effect. Besides that I also created a CSP (Communicating Sequential Processes) gem for Ruby called Emit (https://github.com/omegahm/emit) This outperformed the current Python implementation in speed.
After my PhD I've been working as full stack developer multiple places, where I've mostly been using Ruby for backend and React for frontend. My latest position was a Tech Lead position where I was in charge of a small team of four developers.
I find that the audio gets out of sync when playing faster than 2x. Have you also noticed that - and perhaps have a solution?
> I can’t think of any reason to directly access the DB from a plugin or theme.
Because it's PHP and it's easy.
I did the same for my girlfriend and I and preloaded it with all approved Danish names (42,000 in total) that we could then swipe through. I made it as a private web app, so that I didn't need to consider authentication.
The second character displays wrong for me when copying into VS code with Cascadia Code PL font.
How? I know exactly zero people who uses it. However, I do see TikTok videos on Instagram and Facebook all the time.
