Moving to a closed development model => opensource is just a gimmick, especially with a BSD licence.

I feel like the project just died.

It’s a good thing because it’s definitely an interesting company worth investing into long term. But not at this valuation. 10% seems reasonable given the profits perspective.

This is misleading and not the point of the wealth tax.

If you’re lucky enough that you don’t need to work for your income, you should be taxed. A lot. How much? Enough to make sure you don’t become so rich that your children don’t need to work.

Being rich is not fair, it’s very rarely deserved, and it needs to be taxed unfairly.

This is great news, maybe people are going to start caring about their electronic gadgets more and not treat them as disposable? Maybe longevity is going to become a criteria again?

And then Apple pay and Google pay are not going to implement it, and nobody is going to use it.

This is incredibly light in details, no verifiable claim as far as I can tell.

(I’m sure they’re not lying, but we’re not learning anything here)

They evolve and they don’t. People call things whatever they want. How is it going for X/Twitter?

I have renamed the bird Türkiye . It was called Turkey in reference to the country, I think it’s fair to rename the bird too.

Well, let's say I just don't understand the popularity of this magazine on HN.

So, nothing new?

The cosmic ray hypothesis has been dominant for a few years now.

That’s… great. But who runs containerised 32 bit applications?

I just contributed this [1] which does what you want for seccomp. Well, not by default, but profiling is now effective against this attack.

Oh, an this [2] just happened

In cryptography, you want operations to run in constant time, even if it’s wasteful, otherwise an attacker could guess information about the key or plaintext by measuring execution times.

Modern compilers are extremely clever and will produce machine code that takes full advantage of modern CPU branch predictors, and reorder instructions to better take advantage of pipelining. This in itself will make the same code run at different speeds depending on the input data.

Then there is the whole issue of compiler version roulette. As a developer you have no idea which version of compilers your users and distros will use, and what new and wonderful optimisation they will bring.

Cryptography and video codecs are notable exceptions, they put a lot of effort to making the code provably memory safe: no recursion, limited use of stack variables, no dynamic allocations, etc. As a result, memory safe languages bring nothing but trouble by making it non deterministic, that’s especially true for crypto where compiler “optimisations” guarantee you side channels attacks.

fguerraz — Fri, 01 May 2026 14:39:57 +0000

Distributions using outdated (sorry “stable”) kernels are stupid.

We are not 20 years ago, the world in which it made sense doesn’t exist anymore, but the industry is slow to move on. Just pick a long term release and update it regularly.

You’re correct, the article doesn’t say anything about that, I’m using my own judgement given the facts that I have.

All I know is, if I was at war with the USA, I would definitely cut the internet in my country. Not doing it is like being at war with a big maritime power, and not protecting your coastline.
