The shell stores the history of entered commands, defines how you set environment variables, how you switch the current

First of all, Firebase is a great choice for some kinds of projects, especially MVPs (Minimum Viable Product). It allows shipping the first versions of your apps faster and cheaper. But it has 3 disadvantages once you get the traction:,Three Linux shells (ZSH, Bash, fish) within the Gnome Terminal. I’ve heavily customized the ZSH shell; Bash and fish show the default. You can see that fish has an in-line autosuggestion feature that the two other shells lack. Image by Martin Thoma.,There are also “programming fonts” like Fira Code or Jetbrains Mono. I don’t like them, because they make it harder for me to really know what is written. They look nice, though.,Considering the sheer number of people who lost their lives to the Spanish Flu, it’s amazing that it had almost seeped out of the public consciousness until we faced a similar reality ourselves.,Download and install all 4 “DejaVu Sans Mono Powerline” fonts. On all systems I know, installing a font is done by double-clicking it. Then a window opens which has an “Install” button.,For a while, we were implementing all the logic on mobile clients. Fortunately enough, we had migrated to Kotlin Multiplatform about a year ago, so at least we needed to implement the logic only once in the common module.,I’d been trying to connect with other queer people in design, to learn more about queer design history, and not getting very far. And so I had a Field of Dreams moment. I decided I was going to build something out in the world and bring the queer people to me.,How many times were you thinking about writing your backend for mobile apps you are working on? And how many times have you chosen Firebase instead? Are there any better options at the moment?,No matter what you take, the font matters. You might want to have a monospace font. And you for sure want a powerline font; trust me with that one. The powerline font gives your shell the possibility to use characters that look like images. It can make the prompt way nicer.,Every shell has a prompt. The prompt is what is written before your cursor. It signalizes that you can enter a command and gives useful context information. In the example above, the prompt contains the user name moose , the current computer pc08 , the current working directory ~/GitHub/MartinThoma/flake8-simplify , the active git branch feature/19 and the fact that there are modifications ±.,Ktor is the first-class citizen of the Kotlin ecosystem, which means deep integration with the language itself and all its features, like coroutines, sealed classes, multiplatform distribution, extensibility, and so on.,Kotlin is fully compatible with any existing Java libraries or frameworks, so you can easily integrate Ktor with Spring or Hibernate, for example. But of course, there are Kotlin-first libraries for the most popular tasks.,Aminal is a Terminal Emulator written in Go. It can be used on Linux, Windows, and Mac. It allows configuration via a configuration file and includes the color and keyboard shortcuts in it.,Pale Rider is a useful book to read if you want to understand about the Spanish Flu and how it changed the world. It provides some hints at what we can come to expect once we come out on the other side of the Coronavirus pandemic.,The book delves into various personal stories and describes how the virus made its way around the world after the end of the First World War. Even in an age where mass travel wasn’t commonplace, the virus managed to find its way to all corners of the globe.
