Very interesting article, even though I'm not a fan of Alan Kay anymore due to the disaster of the STEPS project: a research project on how to better create software which results in papers and demos but not (or very little) software s

I don't think that's really true, let's suppose that your unsafe code has a presupposition that cause an UB if not met. If this is a bug and you can remove the presupposition, great, but is-it always possible without performa

This is the classic configuration problem: a program is too complex for users, we'll use configuration files. Then configuration becomes more and more complex so either your configuration file language becomes an ugly programming langu

Memory protection only adds a small performance hit that's true but it also requires a totally different way of working. I don't know much about Amiga but I remember that when reading about Synthesis (a very fast & low latency

And Amiga had no memory protection which means that it would be very unsafe to use Internet with it. That said BeOS was quite responsive and had memory protection, but still inadequate security for modern security attacks.

I disagree that this is only a software issue: relying on only one sensor is a system issue in the MCAS not a software issue.

Not sure, ensuring 1) that the regulation organisms do their job instead of relying on Boeing 2) that the 737 Max MCAS system relies on 3 sensors seems good enough no?

Funny,I tried two years ago to use Nix to have a new onegcc on an old Linux OS, I didn't succeed and finally recompiled gcc from the sources which I found much easier (and better documented) than using Nix.

Interesting, do you have studies on this topic? That said the 'CPU costs' of adding these branch are mostly ICache usage cost so benchmarks aren't very useful..

A) Overpopulation isn't only about space, it's also about resource usage and the wastes generated (including CO2). B) you're free to live on the Moon or on Mars once(IF) it becomes possible but 1) the ticket price is VERY exp

For an ISA whose main use will be IoT (at least in the beginning), this isn't good.. Rust didn't put integer overflow checks in release mode because current CPU don't provide "free" integer overflow detection, RISC

Extending the array is not needed: you can store the last element in a variable, then overwrite the last element with the searched value, do the search then restore the last element. I remember a talk from Alexei Andrulescu(sp?) where he ta

Honest question: what is so bad about having to create one process per core? If you have lots of data you can use shared memory, so the performance should be similar no?

Oops, I meant that even though VScode has many flaws (copy paste from the LinuxVM to Windows doesn't work), it still work better for me than Eclipse, CLion or Vim.

What I don't like about VScode for C++: sometimes find source is very slow (much slower than doing a grep and opening the file yourself), and it opened the wrong file for one of my colleague, and find usage never work. And I never mana

Maybe, but you forgot something: memory fragmentation, if this HW solution enable a "bup the pointer" allocation and also allow "real time" deallocation (I don't know I cannot access the paper), the result could pro

I couldn't access the article but the quote you give is weird: in the ages of kings, the masses thought that the elites have too much for centuries before the revolution happened.
