Guidance on building Knockout ViewModels with safe computed observables, dependency checks, and failure avoidance.
Learn how to set up Jira Align's PI planning board to visualise team capacity and cross‑team dependencies, rebalance load before committing, and avoid common pitfalls.
An architecture note covering the requirements, minimal design, trust boundaries, operational checks, failure modes, and conditions that would prompt a redesign of Xcode’s New Build System.
Goal: Configure the TeX engine so that a format file (.fmt) is automatically considered stale and rebuilt whenever any of its source .tex or .sty files are modified. Constraint: The current caching mechanism does not track file timestamps or content changes of the inputs, and there is no way to declare a set of directories that should trigger regeneration wi
I'm designing a view model in Knockout 3.x where a computed value derives partly from observables and partly from state that Knockout cannot track, such as the current clock time or a value held in an external store outside the observable graph. My understanding is that ko.pureComputed sleeps whenever it has no subscribers: it stops re-evaluating, ignores ch
When using observable.get(key, fallback) to safely read a property that may be undefined, MobX returns the fallback value without registering the property as a dependency. The goal is to have any observer or reaction that relies on this property re‑run when the property later becomes defined, avoiding stale UI state. Currently the access does not create a de
Goal: Verify if Jekyll’s incremental regeneration (enabled with --incremental ) reliably rebuilds every page that references a changed global data file ( _data/*.yaml ). Uncertainty: Although the .jekyll-metadata manifest marks data files as dependencies, some observers note that dependent pages are not regenerated after a data file edit, requiring a full re
