Profile-sync-daemon (psd) is a small pseudo-daemon designed to manage the
browser's profile in tmpfs and to periodically sync it back to the physical
disc (HDD/SSD).
It accomplishes this via a symlinking step and an innovative use of rsync to
maintain backup and synchronization between the two.
One of the major design goals of psd is a transparent user experience.
Auto-suspend inactive X11 applications. 👀 💻 💤 🔋 Save battery by auto-suspending unfocused X11 applications.
Modern GUI applications tend to use significant system resources, such as CPU time, even when they're not being actively used.
XSuspender configurably suspends application activity (using Unix signal SIGSTOP or a custom shell script) shortly after its window(s) loses focus. When the window regains focus, the application is transparently resumed exactly where it had left off.
PoWA is a PostgreSQL Workload Analyzer that gathers performance stats and provides real-time charts and graphs to help monitor and tune your PostgreSQL servers.
bpftune aims to provide lightweight, always-on auto-tuning of system behaviour. The key benefit it provides are
- by using BPF observability features, we can continuously monitor and adjust system behaviour.
- because we can observe system behaviour at a fine grain (rather than using coarse system-wide stats), we can tune at a finer grain too (individual socket policies, individual device policies etc).

Hypothetical Indexes for PostgreSQL. HypoPG is a PostgreSQL extension adding support for hypothetical indexes.
An hypothetical -- or virtual -- index is an index that doesn't really exists, and thus doesn't cost CPU, disk or any resource to create. They're useful to know if specific indexes can increase performance for problematic queries, since you can know if PostgreSQL will use these indexes or not without having to spend resources to create them.
