It's odd that you were using ring buffers in 1992 for low level code but don't understand the value of avoiding a modulus instruction. Masking is far more efficient and often a ring buffer will be used in code where performance is

The only thing which matters when considering "The People" is their aggregate "generalization" -- contrasted with these uber wealthy where a handful of them can make an actual positive impact on climate change where the

There are big minds without power/wealth and also far sighted people without. You pretty much need both in order to do something significant which doesn't align with the overall will of the general public.

But that's a reflection of "The People" and their will. People want their existing jobs and status quo. They care about next week's pay check. Not a theoretical tidal wave that people they don't know say will happen

Everyone gets it wrong much of the time, seems like the question may be more about who gets it wrong a little less often.

But it isn't the role of the representatives to come to terms with science, it's their role to come to terms with the will of "The People" (the tangled mess of what that means). I think it could be argued that the will o

It would have some interesting implications, politically. The democratic sense of "The People" rejected the issue and failed to take care of it through democratic and mundane day-to-day decisions. But the uber-wealthy who are ofte

I'm not sure to what extent exactly, but iirc they instrument APIs and pass them through IPC. It may not really be the best example, for some reason it popped into my head but maybe it was an incorrect assumption.

I work with video codecs now, but anything computationally intensive and/or close to the hardware will benefit from some assembly code. The three that you mentioned are good examples. The web browser you're using to view and respo

I program assembly as a large part of my daily job, and we generally target between 500% and 1500% speedup for our assembly routines. That number being compared to C code with all compiler optimisations enabled. 1.0x - 2.4x is indeed pretty

Not true at all - the core atomic operations are very well understood by now and are supported on any modern CPU.

Cooperative multi-tasking doesn't always mean a per-worker queue is feasible. Really the only time I could see that being feasible is if the work queue is constantly saturated. Often times you just don't know in advance which work

If you want to learn how to read X86, don't choose this AT&T style syntax as it's a monstrosity.

Being a person who programs actual ARM/Neon assembly for both iOS and Android, your post is hilarious. ObjectiveC and Java are anything but assembly.

If it's too difficult for you to use, then use another language which holds your hand more. But for many of us, it's an incredibly powerful language and there isn't really anything comparable when you need to squeeze every in
