Reliable Software with Ada
Discover the language trusted to power avionics, rail transit, and mission-critical infrastructure. Learn how Ada eliminates whole classes of bugs using strict typing, range boundaries, contracts, and native concurrency.
Like Duolingo, but for Reliable Software with Ada. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through The Safety-First Mindset and Architecture and Concurrency. It starts from scratch.

Key ideas in Reliable Software with Ada
- Ada subprograms begin with the procedure name and end with a matching 'end <Name>;' statement
- Labeling the end statement with the procedure name allows the Ada compiler to instantly flag mismatched or unclosed blocks
- Omitting the matching identifier on nested or top-level blocks triggers a compiler error or warning
- Ada.Text_IO only prints strings and single characters, not arbitrary numbers directly
- Printing numeric values requires dedicated type-matched I/O packages such as Ada.Integer_Text_IO or Ada.Float_Text_IO
- Ada eliminates runtime format string crashes like C's printf by checking I/O types at compile time
- Ada refuses to implicitly widen or coerce integers into floating-point numbers
- Mixing distinct numeric types in arithmetic requires an explicit type cast written as Target_Type(Value)
- The Ada compiler catches mixed-type expressions at compile time to avoid unintended truncation or precision loss
- Ada is case-insensitive, meaning `My_Var`, `my_var`, and `MY_VAR` all refer to the exact same identifier
- Ada's design prioritizes human readability and team consistency over case-distinguished identifier tricks
- Reserved keywords like 'begin', 'loop', and 'end' can be typed in uppercase, lowercase, or mixed case without changing their meaning
- In Ada, using 'type' creates an entirely new type that cannot be implicitly mixed with other types
- Even if two types share underlying integer ranges, the Ada compiler forbids assigning one directly to the other without explicit conversion
- Range constraints in Ada specify the absolute minimum and maximum legal values for a type
- Ada checks these bounds during compilation or at runtime, preventing numbers outside the range from slipping in
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Reliable Software with Ada the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
