Why do you say this? The post is quite clear that marking the memory region as NX fix the issue caused by speculative execution.

Read about the AF447 Rio-Paris crash. Input stick averaging?? That's a huge design mistake which contributed to the crash and AFAIK is still here..

You're phrasing this as if using an IDE was always an advantage, but unfortunately this isn't always the case: -IDEs are more resources hungry, I remember when trying to use CLion on a big C++ codebase, until increasing the garbag

One thing I noticed with your clever encoding is that you can avoid some nops: instead of having 2 15 bits instructions followed by two nops, you could have two 30 bits instructions, saving maybe a little decoding energy. Also the 60bit for

So a VLIW, interesting but usually compressed instructions are at most two-registers..

If the language is Java which puts the GC in nearly everything you're f..., other languages have GCs and nonGC'd data so you go to the wonderfull world of manually managed objects with its use-after-free..

Congratulations your language is trying to solve an hard problem. But .. your language mostly hide when you're doing an 'inside' function call or an 'external' function call. I'm not sure I like this; 1) the la

This part is very bad, 99% of the time if you overflow a 64 bit variable it is because you did the wrong computation , not because you need BigInts..

Not the only one though: I remember what happened when we 'invaded' Lybia: not one criticism in the French news anywhere, total censorship, even though our media had widely and correctly criticised the US for the Irak war.. So I t

Bah, each time someone say this they "forgot" that one side effect of 'every frame is perfect' is that it can increase latency.. Perfection or latency? That should be the user's choice not the developer's..

1) the name is a discoverability issue for non-german people. 2) In the examples, the placement of & is incoherent: sometimes it's 'i64&', sometimes it is 'i64 &', pick one (I prefer the first). 3) const

Yes and being 'opposed' to QM contributed to expose the 'spooky action at distance' that QM implies, which is very important.. It's a pity that experimentators were able to demonstrate it only a long time after Eins

Note that in Zig, unsigned integer have the sqle semantic qs integers on overflow (trap or wrap or UB). You also have operators providing wrapping. That is the correct solution.

I worked (a long time ago) on a C project where every int was wrapped in a struct. And a friend told me about a C++ project where every index is a uint8, uint16, and they have to manage many different type of objects leading to lots of bu

I've seen some issue with this approach is that management will want to sell the prototype, bypassing the "rewrite from the lesson learned" step, and then every shortcut took into the prototype will bite you, a lot .. And th
