All food ingredients website (organized)

Lorenzo Tinfena — Tue, 01 Feb 2022 16:43:15 +0000

A cool idea can be a website with a database with all possible food ingredients / food commodities from all the world, with all history and uses. Food commodities includes animals, and plants, but only edible animals and edible plants, and where find them. Maybe how feed/grow them. All possible spices, and even refined commodities like all type of flours, (so not only wheat, cause also it can be used as main ingredient of a dish). All this with a great organization, because I hope not only me I become mad understanding different types and most important names of flours. Names can include a map with local names for some ingredient, (here in Italy every region has its names for cuts of meat)

If else return break best practices

Lorenzo Tinfena — Tue, 07 Dec 2021 22:30:31 +0000

Do not write:

func () {
    if (something)
        return true;
    return false;
}

Instead write:

func () {
    if (something)
        return true;
    else
        return false;
}

Do not write:

func () {
    while (somehing)
        if (somethingelse)
            break;

}

Instead write:

func () {
    while (somehing)
        if (somethingelse)
            return;
}

These are my current best practices, what do you think?

Pepper - open source Chatroulette app

Lorenzo Tinfena — Wed, 01 Dec 2021 11:56:44 +0000

[Edit]: I finished it!
Download: https://play.google.com/store/apps/details?id=pepper_client.pepper_client.pepper_client
Source code: https://github.com/lorenzotinfena/pepper-client

This app us built in go (server) and flutter (app ios and android), it used grpc for apis, and remote container extension for development of the server (using docker)

The app is not yet puclished, and i think im not going to add ads inside, only donations, so it will be free, i think i will publish it only on play store due app store restrictions for chatroulette apps

In a chan like context.Done() is there difference using struct{} or interface{} types in Go?
