As domain driven design practitioners, we have to design datastructures a lot. Often we have to encode our knowledge into a not-so-expressive type system. That's when the trouble starts: our types don't represent exactly what we have.Read (in english 🇬🇧) || Watch 📹 (in english 🇬🇧)
Something strange happened at Clever Cloud: everybody has started using rust, little by little. Many greenfield projects are using rust. That's not to say we've stopped using scala, java, or ruby (and even a bit of go and haskell). As a CTO, how do I keep complexity and language diversity in check? How do I choose which language to use for projects? Do I let others choose?
React and flux have shown us how to design UI in a modular fashion. One of the core ideas, is that data should always flow in one direction. With this concept, it's easier to build applications from independent modules. I'll show what react core concepts are and how they allow developers to manage complexity in big applications.Read (in english 🇬🇧) || Regarder 📹 (en français 🇫🇷)
Scala, by being both Functional and Object-Oriented is easy to get started with, especially for java developpers. However, to get the most of the language, you have to embrace its functional nature.Read (in english 🇬🇧) || Watch 📹 (in english 🇬🇧)
Dans le monde du compile-to-js, il y a des langages proches (genre coffeescript), et des langages qui vont un peu plus loin (genre typescript). Et puis il y a purescript. Ce soir, on verra le pourquoi et le comment, avec la bibliothèque halogen, qui permet de créer des applications/interface graphiques.Read (in english 🇬🇧)
Rust is touted for systems programming, but there are web stacks available: iron, nickel, rouille, now rocket. Web dev in rust, is it doable yet?Read (in english 🇬🇧)
Backend programming sounds hard. But we all know what really strikes fear in the hearts of backend devs: CSS. Building a simple page layout is a daunting task: you need to juggle with floats, margins and all that sort of things. But what if I told you handling layout in CSS has improved dramatically? Or, Djikstra forbid, that it's now kind of easy? Let's see what we can do with flexbox and grid; I promise you you won't be scared of CSS layout anymore.
After some heat, systemd has replaced initd in many GNU/Linux distros. Why? Is it hard to write a systemd config file? How does it work? How do you replace cron?Lire (en français 🇫🇷) || Read (in english 🇬🇧)
Test-Driven Development is widely accepted as good practice. But can we do better? By specifying your program's behaviour with types, you can go a very long way, with more confidence and with less hassle than with tests.Read (in english 🇬🇧) || Watch 📹 (in english 🇬🇧)
It can be usual for software developers to let the ORM take care of the database schema. In many cases it's a bad idea as it makes the data stored in your database brittle and hard to use confidently. I'll show a few tricks which will help you cleanly store and query data by using your database engine to its full power.Read (in english 🇬🇧) || Regarder 📹 (en français 🇫🇷)
