This sounds like an exokernel design. What forces you to use the compiler that generates the trusted code to replace the MMU?

Perhaps instead of distributing program executables, we can distribute program intermediate representations and then lazily invoke the OS's trusted compiler to do the final translation to binary. Someone suggested a Vale-based OS along these lines, it was an interesting notion.

It is, time to convert all projects back to C !

From the perspective of a consumer, my MacBook Pro is basically the perfect laptop, at least in theory. I love the battery life and performance of the hardware, not to mention the unrivaled build quality of the MacBook (screen, trackpad, keyboard). In practice, however, MacOS limits the capabilities of the hardware such that I cannot daily drive my MacBook Pro as a work or personal computer (poor containerization sup…

My biggest complaint is that I have a "16-core Neural Engine" in my MacBook, but nothing that can be run on it. Sure, internal macOS tools such as the fingerprint reader or even webcam might use it, but not a single ML project on github makes use of it. I can be lucky if ML projects don't depend on CUDA to run.

Their results are invalid because they used Cinebench. Cinebench uses Intel Embree engine which is hand optimized for x86, not ARM instructions. In addition, Cinebench is a terrible general purpose CPU benchmark.[0] Imagine if you're testing how energy efficient an EV and a gas car is. But you only run the test in the North pole, where the cold will make the EV at least 40% less efficient. And then you make a conclus…

Cinebench/4D does have "hand-optimized" ARM instructions. It would be a disaster for the actual product if it didn't. That's what makes it interesting as a benchmark: that there's a real commercial product behind it and a company interested in making it as efficient as possible for all customer CPUs, not just benchmarking purposes. Albeit for later releases this is less true since most customers have switched to GPUs…

I understand that corporations are bastards and built on foundations of the crushed skulls of children and involuntary human sacrifice but Office on the Mac is not a bad product and is improving. But the windows version has just been around longer and had more work done on it. And don’t get me started on LibreOffice - it’s buggy as hell. Even more than Office on a bad day I’ve met Bill. He wouldn’t be out of place am…

I wasn't talking about the product - I was talking about MS using the product to lock the whole world into its own =proprietary= format (so no one could reliably open & process it - and then others got blamed for it, not Microsoft), AND then aggressively attack those who try to escape from its lock, even countries.
