[$] Stabilizing Rust's never type
A function's return type is supposed to indicate the kind
of data that it produces. Rust's "never" type, which is denoted by an
exclamation mark ("!"), is the type the language uses to mark a function that
never returns and other places where a value can never occur. For a long time,
the never type was used internally by the compiler, but was considered an
unstable feature. On August 24, after more than two years of work, Rust-
compiler-contributor "waffle" finally managed to stabilize the type. It took so
long, in part, because it involved a small breaking change to previous Rust
editions, which the compiler maintainers needed to ensure did not impact much
real code.

[$] CERN's migration path from CentOS Linux to Debian
The European Laboratory for Particle Physics, usually just
called CERN, is not only the birthplace of the World Wide Web, it is home to the
Large Hadron Collider (LHC), the world's largest and highest-energy particle
accelerator. As such, its computing environment is both truly unique and of
great interest to people outside of CERN who hope to find lessons applicable to
their own computing needs. The upcoming migration of some of CERN's systems from
CentOS Linux to Debian, which was the topic of a talk at the recent
MiniDebConf Winterthur 2026, is of particular interest.
