Welcome to the hello wiki!

This repository is currently just a placeholder for this wiki, where ideas are collected on hello. Partly inspired by my six-part series about #LinuxUsability.

Objectives

  • Build a modern, elegant desktop operating system that conceptually matches the simplicity of Macintosh System 1
  • Binary compatibility (newer apps always must run on older versions of the OS)
  • Visual elegance matching the conceptual elegance (check out the work of people like https://alexanderustinov.tumblr.com/... let's collect some more here)
  • Lots of polish
  • Dedicated to personal computer desktops with as little complications as possible (no server stuff, no mobile stuff)
  • Be able to run the "Libre Graphics Suite"
  • Be able to run on inexpensive devices (e.g., ARM-based embedded systems)

Design principles

Technology

  • FreeBSD based (not Debian or Ubuntu because the "Linux Desktop" is a mess beyond repair)
  • Or Haiku? Is Haiku actually "hello" done consequently (whole stack)?
  • The operating system is contained inside a single read-only image that the user cannot mess with (think of it as the "System" file in Macintosh System 1). This is booted using SystemImageKit
  • AppImages are used for the applications
  • A custom or customized desktop environment is used that uses concepts (not: copies the look and feel of) Macintosh System 1 and Mac OS X around 10.4, e.g., global menus, application bundles, no launcher, no applications menu, no app store, just drag-and-drop in the file manager
  • (At least) the ABI guarantees and lifecycle of RHEL/CentOS

What to do

  • Stand on the shoulders of giants
  • Change the world

What NOT to do

  • Build yet another "Linux distribution" with a Mac theme on an existing desktop environment

Classic MacOS

In the original 1984 Macintosh desktop, every application was a single file that could be freely moved around in the file system. No installation was necessary. The system used a desktop database that automatically associated files with the applications that had created them (using the type and creator resrouces). The desktop information was stored in two files, Desktop DB and Desktop DF).

Note that when after the merger with NeXT, Apple went on to create Mac OS X, they explicitly stated in 2000 (16 years after Classic Mac OS) that it was their objective to match that level of simplicity for modern applications.

NeXTStep, NeXTSTEP, OPENSTEP

NeXTSTEP was an operating system launched by Steve Jobs' NeXT Computer in the late 1980s and is the predecessor to today's macOS. It had a concise concept application system integration. Let's the system describe itself:

This is how NeXT Workspace Manager (in 1989) automatically handled file associations using the Apps directory. Note that no files (other than the application itself) have to be copied around, no databases have to be manually triggered.

The applications themselves were directories that the file manager showed like files, but the terminal showed like directories:

Mac OS X

When Mac OS X was created around 2000, Application Packaging and Document Typing merged the simplicity of Classic Mac OS single-file applications with the benefits of NeXT-style application directories, and introduced a new bundle format and Launch Services. This is explained in detail in

BeOS

What needs to be built

Branding

  • Some variation of a handwritten "hello" that fits into the series of existing ones but does not 1:1 copy them. The original one from 1984 had a loop in the "h" and a dot at the end and looks a bit quirky, as if it was really drawn with the mouse. The iMac one had no loop and no dot and is much more slick, as if it was drawn with a tablet. Original Mac icon designer Susan D. Kare is selling a pixelated version from 2012 with no loop but a dot
