Or, if you have a semi-locked down production box and a process that's already gone unusably slow, a quick shell loop that calls pstack on the slow process 10 times will get you a good idea where the process is spending its wall clock

Presumably that's legal, as long as there isn't a clear correlation between excluded neighborhoods and protected classes. I'm not a lawyer. This is not legal advice.

I agree that is was good the designers of the 386 got rid of some cruft in designing 386 protected mode. It's unfortunate they didn't lean harder into BIOS calls to hide implementation details (such as allowing only the BIOS to m

One could, but then one would give up the advantages of a relaxed memory model.

Yes, the MIT 6.270 robot competition in January 1998 definitely ran the robot using a C interpreter on an ARM board.

I think re-targeting bitcode for a different architecture with the same pointer size and endinness is a pretty light weight operation, but I might be wrong. I'm pretty sure it's orders of magnitude lower overhead and less complic

> Fundamentally, a C binary will not run on multiple architectures (at least not without some sort of special translation mechanism like Rosetta or qemu user-mode emulation). The C machine model doesn't dictate native compilation.

Very nice. I hope that in the future, native code will be the distribution format about as often as we write inline assembly. Sometimes you'll really need precise control over instructions, but for 99% of code, it's not worth th

This is great for x86, but for low-overhead multi-platform binaries, IBM came up with a pretty good solution decades ago with OS/400 TIMI (Technology Independent Machine Interface), which is basically Android Runtime's install-tim

It's really unfortunate that there are no commercial incentives to provide strict sandboxing for outdated versions of applications, rather than only allowing the latest version to be installed. There's a strong public good in pre

Read The Hitchhiker's Guide to the Galaxy, and post back here. Minor spoiler: mice (okay, not rats) are projections into our universe of immensely powerful trans-dimensional beings, or something like that.

Julian Assange and a couple of others developed a file stem called Rubberhose to avoid this problem. All of the filesystem structures, data, and free space are indistinguishable from noise without the decryption key. The system always set

Interesting, and I presume it works for singletons of any type, correct? val x: 1 = 1 val y: 2.718281828 = 2.718281828 That's kind of cute. I presume its main purpose is for overrides in order to get something similar to

This creates two types with quotes in their type names, and then creates a union type of the two? Then the compiler needs to determine if the token's context requires a type or a value, and disambiguate accordingly? In the example abo

But isn't that just what you were suggesting in the GP post in order to get rid of a layer of indirection?
