firenze.dev

firenze.dev
Firenze.dev is an open community for developers based in Firenze, Italy that organizes events, talks, and meetups for developers. I founded the community with a friend of mine. The main goal of the community is to provide a platform for developers to share their knowledge and experience.

NFT Scan

What's in the wallets? NFT wallet scanner is a nice application to see the NFTs present in an ethereum wallet. It works on the mainnet and on Polygon.

Crypto sbarzotti

Crypto sbarzotti

Crypto Sbarzotti is a collection of 10.000 unique characters registered as NFT (Non-fungible tokens) in the Ethereum blockchain, They are realized as pixel art. They are unique and unrepeatable, each character is different from the others. The Crypto Sbarzotti are created using an algorithm that establishes the specific features and make them unique.
I made this project when starting to play with the Ethereum blockchain, NFTs, smart contracts and decentralized apps.

Yet another React.js State machine! This oine is a tiny and solid 3kb library. This project provides some hooks to manage the global state of a React application. Think about it as a simplified and easy to use version of Redux.

Kittens, blockchain and Web3: let's create an NFT together

Codemotion - Workshop Fest
Codemotion - Workshop Fest
Abstract:

Do you nod silently when NFT is discussed in the bar? Do you change the channel when the news talks about it? Do you make up an excuse when mom asks you for advice about cryptocurrencies?
Everyone is talking about blockchain. Yet it is not so easy to find your way around Web3: the technologies that are part of it are fascinating, but very complex, and for those taking their first steps, it is all too easy to lose your way.
In this workshop we will guide you to discover these technologies through the development and publication of a real NFT, to enable you right away to create decentralized applications on blockchain.

Abstract:

Web 3.0 è una buzzword che ultimamente potreste aver sentito molto spesso. Tutti ne parlano e non si è alla moda finché non l'aggiungiamo alla nostra bio di Twitter. Ma cos'è, e perché è nella mente di tutti? Il Web 3.0 rappresenta la prossima versione di internet, che promuove protocolli decentralizzati basati su blockchain e mira a rimettere al centro di internet gli utenti.

Developing a decentralized application on Blockchain

Codemotion - Edu Path
Codemotion - Edu Path
Abstract:

La blockchain non viene utilizzata solo per fare speculazioni economiche. Nel 2015 è stata rilasciata la blockchain di Ethereum che permette di costruire vere e proprie applicazioni come quelle che usiamo tutti i giorni. Il vero cuore di queste applicazioni sono gli smart contract. In questo EduPath costruiremo e deployeremo un'applicazione decentralizzata che gira su blockchain, imparando cos'è e come funziona uno smart contract.Guarda questa serie di brevi video approfonditi e acquisisci in pochi minuti delle skill da mettere in pratica già da subito!

Il termine Metaverso è sulla bocca di tutti, ma ancora non esiste una definizione precisa di cosa sia. In questo panel andremo ad approfondirlo, andando oltre le nebbie del marketing e della fiction e narrativa sci-fi. Analizzeremo il metaverso dall'ottica delle sue tecnologie fondanti e cioè blockchain, realtà virtuale ed aumentat, intelligenza artificiale. Dalla loro convergenza si concretizza la possibile rivoluzione tecnologica e sociale dei prossimi anni.

Ui framework incompatibility

CSS day 2021
CSS day 2021
Abstract:

At last, the Designer delivered the mockups of the new app. But... Oh my gosh! The framework we use does not have rounded and long buttons. If the designer likes it right there, We have to customize the framework... One month later: We just finished customizing ed extending the framework. Now it sucks! And sometimes it doesn't work in Internet Explorer. In this talk, we're going to talk about how to face the incompatibility between the UI of an app and the framework that is chosen to build it. For example: If the designer wants rounded buttons but the framework has them squared, what should you do? How do you solve this problem? Who is right? Should you change the design or customize the framework? Should you pick another framework? Should you change the designers? Or maybe the developers? Are UI frameworks necessary?

GraphQL - it's time

Abstract:

Do you like to chat about tech with your colleagues and friends? Or share your experience about a problem, but you can't find the proper place or time to do it? What's better than joining a live session and be interviewed about that topic? In this live session hosted by @devmy, I chatted about GraphQL, the popular API "language". We talked about what GraphQL is, what problems it solves, and what are the best practices and advanced scenarios for using it. The chatting session format is straightforward and it works like this: the host asks a question or proposes a topic, and the interviewee answers and explains it.

Let's Talk!
