Bluesky’s Stackable Approach to Moderation - Bluesky
Today, we’re open sourcing Ozone, a tool that lets a team of moderators or curators collaboratively review reports, create labels, and inspect content on the atproto network. Later this week, we’re opening up the ability for users to run their own independent moderation services.

A new filesystem for pidfds
A new filesystem for pidfds
The pidfd abstraction is a Linux-specific way of referring to processes that avoids the race conditions inherent in Unix process ID numbers. Since a pidfd is a file descriptor, it needs a filesystem to implement the usual operations performed on files. As the use of pidfds has grown, they have stressed the limits of the simple filesystem that was created for them. Christian Brauner has created a new filesystem for pidfds that seems likely to debut in the 6.9 kernel, but it ran into a little bump along the way, demonstrating that things you cannot see can still hurt you.

A look at Nix and Guix
A look at Nix and Guix
Nix and Guix are a pair of unusual package managers based on the idea of declarative configurations. Their associated Linux distributions — NixOS and the Guix System — take the idea further by allowing users to define a single centralized configuration describing the state of the entire system. Both have been previously mentioned on LWN, but not covered extensively. They offer different takes on the central idea of treating packages like immutable values.

time_t is not GMT
time_t is not GMT
When I hear someone say "a Unix timestamp is in GMT" I die a little inside. It is muddy thinking that leads to many of the problems that plague this modern world. A time_t does not have a time zone at all. It is a point in time, a scalar value. A 'struct tm' is a point in spacetime, a vector value. If you are trying to express a point in time to a human, you could do that by saying ...

Not so quickly extending QUIC
Not so quickly extending QUIC
QUIC is a UDP-based transport protocol that forms the foundation of HTTP/3. It was initially developed at Google in 2012, and became an IETF standard in 2021. Work on the protocol did not stop with its standardization, however. The QUIC working group published several follow-up standards. Now, it is working on four more extensions to QUIC intended to patch over various shortcomings in the current protocol — although progress has not been quick.
