Ask HN: Qt style "Signals and Slots" based JavaScript UI library?
3 by tmbsundar | 0 comments on Hacker News.
Are there any equivalent of Qt style loosely coupled "Signals and Slots" based JavaScript UI library? Qt allows widget/ components to be connected to each other with a pub-sub type of system where the emitter of the signal really need not care who the consumer is. While, IIUC, most JS libraries follow a hierarchically coupled state passing system where sharing of state happens through props/ passing down from parent to child components with lifted state etc., Was wondering if there are any JS libraries which operate in the style of Qt event driven signal-slot connections as a primary paradigm.

New ask Hacker News story: Debian Testing/Trixie removes systemd-resolved

Debian Testing/Trixie removes systemd-resolved 6 by iam-TJ | 0 comments on Hacker News. Debian's systemd maintainer today removed both systemd-resolved and systemd-nspawn packages [0] from Testing/Trixie/Debian 13 - soon to be in feature freeze - due to disagreements with the Technical Committee [1]. For operators already using Testing/Trixie/Debian 13 this will lead to dependency version conflicts and/or loss of existing service; for upgrades from Stable/Bookworm/Debian 12 likewise. systemd-resolved package depends on the exact same version of other systemd packages. When they try to upgrade to newer versions the installed-but-orphaned systemd-resolved package will prevent it unless it is removed. New installs can use resolvconf.
