Type-to-answer in six languages
Globdrop's interface speaks six languages but its flag names only three. How normalisation, fallbacks and autocomplete behave in Chinese, Arabic and Japanese.
Building software
How Andamio and Globdrop are built: Andamio's scheduler and its three views, Globdrop's six coordinate systems and 19 KB of JavaScript, where the rendering time goes in each, and why one keeps its data in localStorage and Ahorreo in IndexedDB. Also how Globdrop's Write mode normalises what you type before comparing it with a flag's name.
The rest of the line is about planning with Andamio: buffers, the critical path and what Andamio actually calculates, the arithmetic of splitting your time between projects, and showing a plan to a client.
Projects: Andamio, Globdrop, Buffer calculator
Where the rendering time goes in Globdrop and Andamio
Globdrop draws one image and two pins; Andamio re-renders its whole Gantt chart on each drag move. What the code does, what we counted, what we still owe.
Decoding symbols: how Write mode works in Globdrop's flag game
What happens when you type a flag's name in Globdrop: the suggestion list, the text normalisation, and the answers it accepts and the ones it rejects.
localStorage or IndexedDB: Where Andamio and Ahorreo Keep Your Data
Why Andamio stores plans in localStorage and Ahorreo uses IndexedDB: size limits, sync vs async, clearing site data, and a JSON export vs an encrypted backup.
How Andamio Works: A Gantt Editor With No Backend
Inside Andamio: a flat task list, a scheduler that repeats until nothing moves, three views, Mermaid import and export, and plans kept in localStorage.
Why Your Project Needs Buffer Time Built In
How buffers work in Andamio (a days field per task) and in our buffer calculator (PERT plus root sum of squares), and why neither is Critical Chain's 50% rule.
How to Calculate the Critical Path, and What Andamio Calculates
The critical path method step by step (forward pass, backward pass, slack), then what Andamio calculates: the forward pass, with finish-to-start links only.
The Fallacy of Multitasking in Project Planning
Three projects at 33% each finish later than the same three done one after another. The arithmetic of partial dedication, and how to plan it in Andamio.
How Globdrop is built: six coordinate systems, one image and 19 KB of JavaScript
Inside Globdrop: scenarios as JSON, six coordinate systems in one file, a map that is a plain image with pins, and the sizes we measured from the build.
How we make a Globdrop map: one image, a bounding box and a projection
Where Globdrop's base maps come from, how we calibrate them in a small in-house tool, how a click becomes a latitude, and why we use one image, not paths.
Client Communication: Using Gantt Charts to Set Realistic Expectations
Showing a plan to a client with Andamio: their tasks as dependencies, deliverables with target dates, review time added to effort, and SVG export.
