Fascinating! Though, I'm not sure I would call that "communicating". Perhaps a more truthful title would have been: "Naked mole rat behavior may be influenced by feeding on hormone-carrying feces of the queen" But

Woah, this is cool. The "Linux" download is x86-64 only; I know 32-bit x86 is dying, so maybe that's not worth your time (I'd tried to download it on an old 32-bit ThinkPad x60 tablet), but an ARM build might get some us

The syscall interface is considered to be Linux's public API, and must very strictly never break backward compatibility. They cannot retire syscalls.

Windows calls their syscall wrapper ntdll.dll, not libc.so; but it's conceptually the same thing. The ntdll.dll ABI is public & stable, the underlying syscall ABI isn't. Several unixoids do the same thing, where their libc.s

by LukeShu 8y ago
OpenBSD doesn't make any promises about ABI stability between releases. That means that all older binaries may stop working when you upgrade the OS, not just older Go binaries.

> Despite that confusion, I don’t think the community’s outrage is driven largely by that. RedisLabs’ post wasn’t ambiguous about the licensing of Redis itself. Yes it was. It has since been edited to be clearer.

by LukeShu 8y ago
I understood the claim as saying that redis itself isn't using the commons clause, and that it's only some enterprise redis modules that are adding the clause to their license.

I think the story here (for HN readers) is that Apple can unlock the iPhone; isn't it supposed to be encrypted? Does Apple having the capability to unlock it mean that the encryption is backdoored? (Other commenters have speculated t

I've always been bothered that Unicomp uses the term "Spacesaver" for their keyboard with less trim; traditionally, a Model M Spacesaver refers to a ten-key-less. The big difference in the feel between buckling spring and MX

Do note that Xinu (1981) predates GNU (1983) by several years.

by LukeShu 8y ago
I'm fuzzy on the history, but I believe that modern Xinu is actually a complete rewrite since sometime in the early 2000s (the linked page says "ports the code to the x86 architecture " again in 2010-2011). In 2014 Dr. Comer

Linux user namespaces work as a 1-to-1 mapping of UIDs. Every UID in the container has to map to a UID on the host, so the UID range of the container is necessarily smaller than the UID range of the host (unless of course the map is the id

You can use the nsenter(1) command to enter the namespace of another process.

Inside of a container (with user namespacing enabled), you won't have the full 32-bit range, and this must all work inside of containers; I'm not sure about other container managers off the top of my head, but systemd-npawn only g

leni536 is correct, the range is specified at compile time. https://github.com/systemd/systemd/blob/v239/doc/UIDS-GIDS.m... However, do note that if the service file sets a User= name, and that user

Things are broken in this case because of a bug , not because of design decisions. All of the features "locking things down" are opt-in in the service file (to avoid "breaking userspace"), and the service file for syst

By itself that would only schedule it before dbus.service if they are both queued to be started; but since we'd like to be using socket activation to lazy-start it, you'll also need to make sure it's queued when dbus.service

by LukeShu 8y ago
That's exactly what's going on here. The systemd service launcher is doing the same thing as unshare(1); calling unshare(2). However, by "default" after you `unshare --mount`/`unshare(CLONE_NEWNS)`, changes made t

sysvinit is short enough to be trivially maintainable. If you're just using it as a shim to load a framework on top of it, you can ditch even more of it cutting it down to around 500LOC (see openrc-init). So that's not a large e

Everything that would have been "a weird problem with Foo Daemon's init script" we now call "a weird problem with systemd". So you think that systemd-timesyncd's service file shouldn't choose the uid at se

That requires GNU Make; neither $(shell) nor ifeq are in POSIX Make.
