Optionals handle this in zig:

Write:

  value = 10;

Read:

Autogenic training [1] is exactly a relaxation technique focussing on the progressive relaxation of body regions. It is very easy to learn and a body-first approch to approach meditative states, which can then be used for auto-suggestion.

Asianomics released a video on how withdrawing groundwater can dramatically lower the elevation of entire cities — I was surprised by how large an effect just a couple of years of human activity can have.

Ask HN: Why does Mozilla now allow to pay for Firefox?

rene_d — Wed, 07 Aug 2024 11:54:30 +0000

I am a happy Kagi user (10usd), I pay for ChatGPT (20usd) und would happily pay for Firefox which is my main browser.

Why does Mozilla not allow to pay for Firefox directly, and only offers supplemental paid products like Mozilla VPN?

I understand that most people would still use FF for free, but what economic reasoning is there to not even allow donations / supporter-tier subscriptions?

(In case there is such an option any pointers would be higly appreciated!)

Around 10-15 years ago I read that Intel had a large somewhat secretive department working on exactly this idea, I believe the article described it as self-assembling sand or goo.

Anyone know what became of it?

rene_d — Fri, 11 Aug 2023 17:30:39 +0000

.ONG was new to me:

"The PIR simultaneously applied for the top-level domain .ong, which is a similarly recognisable initialism for "organisation non gouvernementale" in French, and equivalent terms in many other Romance languages such as Spanish, Portuguese, Italian and Romanian." [1]

So similar to e.g. NATO and OTAN.

I am building an on-premise annotation platform for medical image data (MVA.ai) where it is used for both backend and frontend (WASM). Really enjoy the language, with the key aspects being the low level control and performance, the build system and cross-compilation, comptime for generics, the easy integration of existing C libraries and the support for WASM. Manual memory management is sometimes a bit tedious, but you get used to it quite quickly. On the other hand, being able to use different allocators can even give you something like 'lifetimes'.
