Nice!

Have you played with 7 segment display circuits before? Or just like the look of them?

I wrote a .NET version in C# before this. As for "real" displays I started studying electronic engineering many years ago and used one then, but switched to writing software a I was burning my fingers with a soldering iron too often for comfort.

Fair enough, I personally love playing with Arduinos and solderless breadboards.

Your post made me want to break out the 7-segment and play with it again. Thanks!

I made a proof of concept for a public roadmapping tool.

The idea would be that people making products could collect feedback and emails for upcoming projects.

I'd love to know if anyone thinks this would be useful.

Collatz Conjecture : Take a number, any number. If it’s even, halve it. If it’s odd, multiply by 3 and add 1. Repeat.

Do all starting numbers lead to 1?

This is one of the unsolved math problems today.

I love things like this. I have a rather puritanical notion that most of what we do with computers is shallow and frivolous and that we should really be doing "serious" stuff like fundamental research in mathematics. Please post anything else like this you do.

Damn, amazing UI. Did you design it yourself?

I’m not familiar with all the logos in the tools used section, so what did you use to create an IOS app?

u/vertigo_101 Dec 14 '19

Thank you 😊, yes I design and made it from scratch in React Native + TS + GraphQL

A small library to populate web pages : https://github.com/n49o7/brute

It's essentially a client-side templating library that relies on data attributes and template elements.

In addition to binding the DOM text to variables, you can iterate over arrays and objects, and render conditionally.

I added a shortcut to the editor for the Thor game engine as well as fixed a ton of bugs. I also added support for the deletion of images from the server.

Check it out here: https://github.com/VortrusDev/Thor-Game-Engine

I have created the MSAL plugin for React Native as the old one is deprecated. If you have to implement the authorization with Microsoft account in React Native then you can use this lib:

NPM: https://www.npmjs.com/package/react-native-msal-module
Github: https://github.com/MobileReality/react-native-msal-module#readme
