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.

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.

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.

I find it interesting that the BBC published this at a time they are already under heavy criticism for their coverage of the war in the Middle East (where they didn’t blink at Trump’s genocidal threats and published an article claiming that Iranians wanted to be nuked).

Now we’re saying that war is just natural. It must be a coincidence.

We have no idea what is in that contract with Google. They get to be the default search engine, but what else? Does it prevent Firefox from accepting some sources of funding, like donations?

It would be great to get transparency on this…
