You can build and run an Expo iOS app on your own iPhone for free

0
·2 views

Developers often assume an Apple Developer account is required before they can start building iOS apps with Expo. The article explains that a free setup works: Expo Go lets you run an app on an iPhone with no Apple account, and a development build on a Mac needs only a free Apple Account for signing. The paid $99 Apple Developer Program becomes necessary when sharing apps with others, cloud-signing builds, or using certain capabilities like push notifications. Libraries outside Expo Go's built-in native code, such as home screen widgets or Siri shortcuts, require a development build. The piece recommends deferring the fee until an app is ready to ship.

Open-source helper adds grid-aware accessibility checks for AG Grid in Jest and Playwright

A developer has built ag-grid-a11y-test, a small helper that adds grid-specific accessibility checks on top of general tools like axe-core. The checks cover issues such as row and column counts under virtualization, unnamed icon-only controls, sort state, color-only status indicators, and keyboard arrow navigation. Findings are graded as error, warning, or info, and the rules are drawn from the ARIA grid pattern and typical AG Grid markup. The package is an early alpha not yet published to npm, so it is installed from a GitHub repository, and the author has not yet validated it against every AG Grid version.

Object storage backup costs hinge on retention and deletion controls, not storage rates

A backup alert often reveals a retention design flaw that predates the incident, such as a tenant's stated retention period not matching what the object inventory actually holds. The article argues that comparing scalable object storage for app backups should account for the full lifecycle of data, including recovery points, storage-class transitions, restore reads, and verified deletion, rather than only the headline per-gigabyte price. It recommends tracking logical bytes, changed bytes, recovery-point counts, export reads, and deletion backlog, and alerting on forecast capacity breaches or approaching deletion deadlights instead of simple size thresholds. The author stresses building a workload sheet with consistent units before evaluating vendors such as AWS S3, Azure Blob Storage, and Google Cloud Storage.

Detecting Missed Realtime Messages in Workspace Presence by Refetching Authoritative State

A developer article argues that a connected socket does not prove a displayed participant roster is current, so clients should track the last accepted sequence number. When a gap appears, the client should replace its view with authoritative state rather than reconstruct it from partial events. The author uses a hypothetical auction workspace scenario, with Go as the illustrative language, to show how a client can distinguish a repaired roster from one that only resumed receiving traffic. The piece stresses that sequence numbers need a clear application contract, including a single ordered domain and snapshots that state the sequence they cover. It also recommends refetching after reconnects and tracking unresolved recoveries as a visible failure condition rather than relying on gap frequency alone.

Court Documents Reveal Meta Staff Discussed Discrediting Jonathan Haidt

Court documents reported by The Guardian indicate that Meta employees discussed a "whisper strategy" to undermine social psychologist Jonathan Haidt, author of The Anxious Generation. Staff reportedly weighed ways to get the academic community to disavow him. Haidt's book has helped shape mainstream policy debates about children's online safety. The original article argues that most screen-time proposals focus only on reducing use, overlooking what the screen itself does for users. It also describes Amblyotube, a Meta Quest app that uses independently shaped views for each eye to target vision problems like lazy eye.
