Developer Launches Free, Client-Side Timestamp Converter With No Data Sharing

·1 views

A developer has added a timestamp converter tool to samtoolkit.com, a collection of around 30 browser-based utilities aimed at developers. The tool converts Unix timestamps in seconds or milliseconds to human-readable dates, supporting UTC and local timezone views alongside common formats like ISO 8601 and RFC 2822. Built using Blazor WebAssembly, all conversion logic runs entirely within the user's browser, meaning no data is transmitted to any server. The tool requires no sign-up, displays no ads, and continues to function offline once the page has loaded. It joins other privacy-focused utilities on the site, including JSON formatters, base64 encoders, and regex testers, all designed under the same no-data-sharing philosophy.

Web Share API brings native OS share sheet to browsers with minimal code

The Web Share API, accessed via navigator.share(), allows web pages to trigger the same native share sheet that mobile apps use, requiring just a few lines of JavaScript. A developer implemented the feature on Forgemage.net, a marketplace for the game Dofus, to let users easily share item requests with others. The API has two key requirements: the page must be served over HTTPS, and the share call must be triggered directly within a user gesture, with no intervening network requests or the browser will reject it. Developers must also ensure shared URLs are absolute rather than relative, as relative paths are meaningless outside the context of a specific host. Fallback handling covers browsers that lack support and cases where the user dismisses the share sheet, making the feature straightforward to implement progressively.

Blameless Postmortem Template Helps Web Agencies Learn From Incidents Without Blame

A blameless postmortem is a structured process that examines how systems, tools, processes, and context combined to cause an incident, rather than assigning personal fault. Published on DEV Community, the template is designed for small web agencies and is intended to be completed in a focused 45–60 minute meeting with a concise written document. The approach separates technical learning from HR, legal, or disciplinary processes, while still requiring clear ownership of corrective actions. Teams are guided to build timelines from evidence, review detection and response quality, and produce a small set of specific actions with assigned owners and due dates. The template also defines common postmortem triggers, such as customer-visible downtime, data loss, emergency rollbacks, and repeated or near-miss incidents.

GPU Has Two Parts: Why VRAM, Not Cores, Determines If Your Model Loads

A GPU card consists of two distinct components: processing cores that perform calculations, and VRAM (video memory) that stores data — a distinction that confuses many engineers new to AI infrastructure. When a large language model is deployed, its weights are loaded into VRAM, not into the cores themselves. The cores continuously stream data from VRAM to perform each calculation, which is why language models generate text word by word rather than all at once. On AWS EC2 instances, the prominently listed system RAM figure is irrelevant to model loading — only the GPU's VRAM capacity determines whether a model fits. For example, a g6.4xlarge instance lists 64 GiB of system RAM but only 24 GB of VRAM on its NVIDIA L4 GPU, and AWS does not display VRAM directly on its EC2 pricing page, requiring a separate cross-reference.

Developer builds nightly AI agent attack system, finds gaps in Google's own tools

A developer created an automated security tool called Crucible that stress-tests AI agents for prompt injection and other vulnerabilities by running adversarial attacks every night at 3am UTC. The system plants detection tripwires in each agent's environment rather than relying on the AI itself to report whether it was compromised. Testing revealed that Google's Model Armor guardrail layer failed to block attacks that succeeded at baseline, including an injection hidden inside a scanned invoice image. Crucible was also pointed at Google's official sample customer-service agent, where a normal-sounding customer message bypassed a guarded discount-approval tool after an explicit rejection. The developer reported the finding to Google's Bug Hunters program, which escalated and closed it as 'Infeasible,' citing the sample-code scope of the repository.
