Developer builds free browser-based image toolkit that never uploads your files

·1 views

A developer has launched ToolBox Image, a free image processing toolkit that runs entirely within the user's browser, meaning no files are ever sent to external servers. The tool uses WebAssembly and the Canvas API to handle tasks locally, including compression, format conversion, editing, and metadata stripping. It supports batch processing of up to 200 images at once via Web Workers and covers 22 distinct tools. Built with Astro, Tailwind CSS, and vanilla JavaScript, the site is hosted on Cloudflare Pages with no backend infrastructure or user accounts. The project was motivated by privacy concerns around sensitive images — such as those containing GPS metadata or confidential content — being uploaded to third-party servers.

Flutter Core Widgets Guide Part 1: 50 Essential Widgets With Code Snippets

A developer on DEV Community has published a reference guide covering approximately 50 of the most commonly used Flutter widgets, organized by category. The categories include basic widgets, layout, scrolling and lists, buttons, input and forms, structural and material components, feedback and overlays, navigation, and more. Each widget entry provides a short description, a runnable code snippet, and a text-based description of how it renders on screen. The guide is designed for Flutter developers who want a quick, practical reference without needing to consult full documentation. Code snippets can be opened and tested directly in DartPad, though users are advised to allow 5 to 10 seconds for the environment to load.

Azure Policy can block dangerously broad blob lifecycle rules in storage accounts

Azure Blob Storage lifecycle rules without filters such as prefixMatch or blobIndexMatch apply to every blob in a storage account, risking unintended deletions or tier transitions. A developer encountered this risk while working on automated blob cleanup and sought a preventive guardrail rather than relying solely on code reviews. Azure Policy can be configured to target storage account management policies and deny any lifecycle rule that lacks the required filters. A custom policy definition, written in Bicep, checks for missing filter fields and blocks the change if at least one unscoped rule is detected. This approach enforces safer defaults especially in shared development or test environments where manual portal changes can bypass standard review processes.

Automated Restore Verification Turns Untested Backups Into Proven Safety Nets

A software engineer revealed that years of nightly backups were never actually tested by restoring them, exposing a critical gap between a backup job running successfully and the backup being genuinely usable. The green checkmark on a backup job only confirms the process completed, not that the resulting files can be restored into a working system. Using Claude Code, the engineer built an automated workflow that verifies every backup shortly after it is taken, capturing proof of restorability rather than assuming it. The approach addresses a well-documented failure pattern where organisations lose data despite having backups, simply because the restore path was never exercised. By making restore verification a scheduled routine rather than a rare drill, the workflow eliminates the hidden risk that accumulates when backup outputs go untested for months or years.

Pure-C TTS engine gains Metal and CUDA GPU backends with major speed gains

Developers have added two optional GPU backends — Apple Metal and NVIDIA CUDA — to qwen3-tts, a pure-C inference engine for the Qwen3-TTS model, while keeping the default CPU path unchanged. On Apple Silicon, the Metal backend reduced the 0.6B model's real-time factor from 1.5 to 0.60 on an M1 and 0.36 on an M2 Pro, with streaming first-audio latency of 314 milliseconds. The CUDA backend achieved an RTF of 0.44 on an RTX 4060-class GPU, scaling down to approximately 0.12 on an RTX 4090. Key performance gains came from keeping weights, KV cache, and activations resident on the device and encoding full decode steps into a single command buffer rather than offloading individual operations. Server-side request batching further improved throughput by roughly 2.8x on Metal and 3.35x on CUDA, allowing multiple concurrent users to be served in approximately the time of a single request.
