Préparez votre foyer aux coupures réseau et électricité : plan familial, sac 72h, SOS, mode hors ligne. Quand tout s

L'application qui prépare votre foyer aux jours où les réseaux ne répondent plus. Parfois, ils s'arrêtent. Tempête, panne, coupure — sans prévenir. Pas de réseau, pas de serveur, pas d'abonnement requis. Tout ce dont votre famille a besoin vit déjà dans le téléphone — et chacun voit que les autres vont bien. Un plan simple, écrit ensemble un dimanche soir. Qui va chercher qui, où l'on se retrouve, ce que chacun emporte. Les téléphones de la famille se parlent directement, d'appareil en appareil. Les messages passent — même quand plus rien d'autre ne passe. * La communication mesh hors réseau nécessite un boîtier mesh compatible. Sa portée et sa fiabilité dépendent du maillage d'appareils…from lastline.fr

  Offline SOS signaling+recovery app for disasters/wars2025 · github.com · ▲163

  A couple of months ago, I built this app to help identify people stuck under rubble. First responders have awesome tools. But in tough situations, even common folks need to help. After what happened in Myanmar, we need something like this that works properly. It has only been tested in controlled environments. It can also be improved; I know BLE is not _that_ effective under rubble. If you have any feedback or can contribute, don't hold back.

  Eigendrum - Draw any shape and hear what it sounds like as a drum▲243

  Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

  OwnTime – a chess clock for your day's priorities▲110

  I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role&#x2F;priority when its time is up. One…
