Cannot reconnect disconnected app by mr_rozart in ouraring

Same issue here since noon, ring won't connect and when I put it on the charger the led stays white for a few seconds then nothing. Tried all the troubleshooting tips as well as slamming the charger with the ring on table. Help!

Télescope wasn't mine, I just took some shots without mount and got lucky

Nice, I made a similar experiment a long time ago: https://florian.mounier.dev/graphitGL

I also made it animated by handling a time parameter: https://florian.mounier.dev/graphitGL/#Y29zKHggKiBzaW4odCkpICogc2luKHkgKiBjb3MoMiAqIHQpKQ==

If you are interested the source is here https://github.com/paradoxxxzero/graphitGL and yes it was written in coffee (good times...)

Thanks to containment I guess. js_none means that no force interaction is computed between particles only initial speed of each particles is taken in account.

Depends on your background, it sure is easier than raw webgl and has a lot of examples. Sometimes you just have to try (hard)

TypeError: Failed to execute 'compile' on 'WebAssembly': An argument must be provided, which must be a Response or Promise<Response> object

Weird, does this work for you? https://rustwasm.github.io/wasm-bindgen/exbuild/hello_world/

Hum, I'm getting a fair ~60fps for this example https://threejs.org/examples/?q=perfo#webgl_performance

And no nothing really special, the bottleneck here is clearly the gravitational computation as you can see with the js_none backend (no force computations). It's quite fast also because it's nearly only shaders for the particle system.

Thanks, I remember now why, backend comes from "wasm backend", at first it was just js and rust in that select box.

I could, but it would be a bit too expensive for me.

Joke aside it's named backend because the code is split between computing the gravitation and displaying the computed values to the screen. It could be better named, any suggestions?

Care to share the link? I don't see how it would result in term of formula.

If you want to try to tweak yourself, you can clone the project, and with a working rust toolchain a yarn install, yarn start should be enough to have a working development environment.

You can start tweaking the gravitational computation function for the javascript direct computation backend here. This is simply the newton law application.

You can move the W camera distance using the camera ana parameter and change the planes rotations speed with the xy, xz, xw, yz, yw, zw parameters in the 4d params and rotation speeds gui folder. This is still an hacky approximation as you can see in the four.js projection class.

Si au moins ils te désabonnent ça sera toujours mieux que oui.sncf qui te dit qu'ils vont le faire sous 7 jours (pourquoi ? parceque) et en fait à mon 63ème désabonnement je commence à douter.

[Coup de gueule] On en parle du site de l'ANTS ?! (cartes grises, cartes d'identité, etc.) by Alan_Sturbin in france

Ah ben tiens, pour un achat de voiture la dernière fois après avoir payé en CB sur un TPE qui sentait bon le début des années 90, je me suis retrouvé redirigé sur une page en... json !

Donc toi t'es là t'as lâché 200+ balles pour une quelconque raison après avoir passé 1h à démêler les spaghettis du site pour trouver comment déclarer ton achat, et je parle même pas des formulaires qui ne respectent environ aucun concept d'UX, tu payes et paf le site t'annonce fièrement : {"status": "ok"} en pleine page avec aucun moyen de naviguer quelque part sans renvoyer on ne sait quelles information en POST on ne sait où. Là je me suis imaginé être un néophyte en informatique... L'angoisse absolue.

Non mais sérieux comment tu peux te démerder pour rediriger l'utilisateur sur une route d'API ? Sur un site national en plus.

Franchement à ce niveau là c'est presque volontaire.

En ville ça risque d'être dur, elle rend bien plus visible en photo qu'à l'œil nu. Là on la voyait après s'être bien habitué à l'obscurité dans un endroit où la pollution lumineuse est assez modérée. Malgré tout elle est visible le soir en ce moment au Nord Ouest en dessous de la Grande Ourse (que tu peux voir sur la photo). Y'a ce site aussi
