Flutter apps can show an in-app banner when an OTA update is ready

·1 views

Over-the-air updates for Flutter apps download in the background and apply at the next launch, so users normally see nothing. Developers who want to notify users can listen to the OverPush event stream, which emits events for a found patch, download progress, a ready patch, and failures. OverPush provides no UI of its own, so the app draws its own banner in its chosen style. The article includes a sample StatefulWidget that displays progress and a restart prompt, and hides the message after a few seconds. The example is placed in the app's builder, and the article links to documentation for a version with a progress bar.

APIOps for Azure API Management: Extracting, Reviewing and Publishing with the CLI

Portal edits to an Azure API Management instance can be silently overwritten when Bicep redeploys the same policy, leaving no record of the change. The article proposes APIOps, which stores APIs, policies and products as files that can be reviewed through pull requests. Ownership is split so Bicep manages the platform while APIOps manages the API surface, controlled by a new apiSurfaceOwner parameter that defaults to bicep. The sample uses the APIOps CLI version 1.0.5, extracting live resources with a filter and running GitHub Actions workflows for nightly extraction and approved publishing. The author notes that nothing was deployed, and that behaviour on a live instance is described only where stated.

From those devices, they allegedly reached internal wallet infrastructure. The theft involved billions of dollars. The episode is cited as a reminder that technical defences alone cannot guard against every breakdown of trust inside an organisation.

Explainer on Crypto Swaps: Exchanging USDT, TRX and Other Tokens Safely

Crypto swaps let users trade one digital asset directly for another through a swap service or decentralized exchange, rather than converting to traditional money first. The process involves exchange rates, liquidity, network fees, slippage and token standards that can affect the final outcome. The article highlights the TRON network, commonly used for USDT transfers via the TRC20 standard, and warns that USDT on TRON is not interchangeable with USDT on networks like Ethereum. It outlines typical swap steps, from selecting assets and reviewing fees and limits to confirming the transaction and checking it on a blockchain explorer. It also distinguishes centralized exchanges, which hold user funds and manage trading, from decentralized exchanges.

agent-browser gives AI agents a command-line browser that returns compact page snapshots

Vercel Labs has published agent-browser, a native Rust command-line tool that lets AI agents control a browser one shell command at a time. Pages are returned as text listing interactive elements tagged with short references, and the browser stays open between commands through a background daemon driving Chrome via the DevTools Protocol. The tool fails loudly when a target is covered, hidden, disabled, or off-screen, and references expire after navigation or DOM changes, requiring fresh snapshots. It can also be reached through an MCP server, and it supports local Chrome for Testing, alternative engines, iOS Simulator, and cloud browser providers. The project, under an Apache-2.0 license, was created in January 2026 and is still being actively updated.
