Is doing business with Inter.link really structurally different from getting connectivity to an exchange like DE-CIX and doing business there? I know that in theory, you get settlement-free peering at exchanges, but only for those networks

There are still emissions during production and decommissioning. And cars are sources of noise and light, and emissions due to component wear (tires and brakes, probably others as well). A specific car may be not as bad as others for the en

Sorry, I meant that something in the package management stack depends on Perl (not APT specifically). It looks like in trixie, it's libpam-modules that pulls in debconf, which is written in Perl. And libpam-modules is required by util-

The Debian base system is much, much smaller. I'm surprised that people consider Python to be part of it. However, APT depends on Perl and the C++ run-time library, so those two languages have been part of the base system for a very lo

Interesting bit about SH-4. I thought that Renesas had previously promised parts availability until 2029?

LLVM is desirable for other reasons (LLVMpipe for example), so investing into an LLVM port is probably a better use of limited resources than improving and maintaining a retargeted rustc for GCC.

by fweimer 11mo ago
As far as I understand it, the m68k LLVM port is not ABI-compatible with GCC on Linux because the alignment is wrong: https://wiki.debian.org/M68k/Alignment (page says that the LLVM packages are FTBFS because of this)

Is this technology used in the Internet core? Or for de-bundling access networks and Internet service? Where I live, access networks use shared media (broadcast cable or GPON), segregating customers through device and protocol obscurity (no

I find https://github.com/typst/typst/pull/7072#issuecomment-338580... more enlightening about what's going on. Specifically the difference between these three: 1/2(x + y) 1/x(x + y)

Thanks. Looks like the original now has some clarifications, including more detail regarding the REX prefixes: https://wiki.osdev.org/X86-64_Instruction_Encoding

It would be really nice to have something like this for the x86-64 variant.

With containers, you usually get incompatible dynamic loaders in the containers (see mananaysiempre' comment; the glibc dynamic linker sees rather active development in some LTS distributions). This wouldn't be possible if the loa

The dependency of glibc on the unwinder (for backtrace, pthread_exit and pthread_cancel) is a glibc packaging problem. You need to plan for replacing glibc anyway because its licensing could switch to (L)GPLv3+ (including for existing stabl

One reason comes to my mind: HTTP is no longer a stable protocol with well-understood security properties. If you deploy it today, people expect interoperability with clients and servers that implement future protocol upgrades, resulting in

I doubt GPL version 3 is the motivation here. https://packages.ubuntu.com/plucky/rust-coreutils The dependencies of rust-coreutils list libgcc-s1, which is GPL version 3.

The problem about DRM in this context is not that it's going to get broken (which is probably true if the product becomes sufficiently mainstream). It will be used to target photographers and take away their rights. With today's c

I meant that the goroutine in the example keeps running. Often this contradicts the reason for having the timeout in the first place.

by fweimer 1y ago
Isn't using time.After for timeouts a bit of an anti-pattern? There is no way to cancel the pending computation.

I don't know if it is intended this way, but there's one useful outcome even with the limited amount of detail disclosed: There are industry partners who work closely with AMD and Intel (with on-site partner engineers etc.), but w

More importantly, C++17 no longer ignores alignment in dynamic memory allocation: https://en.cppreference.com/w/cpp/memory/new/operator_new C++11 already had alignas, but it was not really integrated wel

Dynamic languages usually come with their own memory manager. They can come up with their own alignment constraints. That being said, most contemporary (Linux) architectures require that malloc returns 16 byte alignned pointers. Some malloc
