Passkeys Aim to Replace Passwords With Device-Based Login

·4 views

Long-standing advice to use stronger passwords has failed to address problems like reuse and easy guessing. Passkeys remove the password altogether by pairing a private key stored on the user's device with a public key held by the website. Logins are confirmed through a fingerprint, face scan, or screen lock, so no shared secret crosses the internet to be intercepted. Major platforms including Apple, Google, and Microsoft now support them, though syncing, setup, and recovery can still be inconvenient. For now, many sites keep passwords as a fallback during a gradual transition.

How Large Language Models Like ChatGPT Work: A Plain-English Explainer

Chatbots such as ChatGPT generate human-like replies by repeatedly predicting the most likely next token, which are small chunks of text. The model learns these patterns through pre-training on vast amounts of text, storing what it learns as numerical parameters, and is then fine-tuned on helpful conversations to act more like an assistant. Most modern models use the transformer design, whose attention mechanism weighs how earlier tokens relate to the next one. Because outputs are built from plausible patterns rather than verified facts, these systems can state false information confidently, a problem known as hallucination.

Public Wi-Fi Risks Today: Fake Hotspots and Login Traps Matter More Than Eavesdropping

Long-standing advice to avoid public Wi-Fi entirely is outdated, since most sites now use encryption that protects the content of what users send and view. The main remaining dangers include fake hotspots set up to mimic legitimate venue networks, phony sign-in pages that harvest passwords, and captive portals requesting excessive personal information. Exposure can also come from devices with file sharing enabled or outdated software that is easier to attack. Experts recommend verifying network names with staff, using apps instead of browser logins for sensitive services, marking networks as public, keeping devices updated, and considering a VPN or personal phone hotspot.

AI Tools Are Making Restaurant Menus Easier to Navigate for Diners

Reading a restaurant menu can be difficult for people managing dietary needs, allergies, or health goals, since traditional menus often lack detailed nutritional information. A new field called AI menu analysis uses natural language processing, computer vision, and machine learning to extract and enrich menu data. These tools can estimate calories, macronutrients, micronutrients, and allergen content, sometimes even from dish images. Combined with user profiles, the technology can highlight suitable dishes, such as vegan options or safe choices for nut allergies, and flag less suitable ones. The article, published on DEV Community, presents this as a way to reduce the cognitive load of comparing dishes on large menus.

How to Optimize SVG Icons for Faster Web Performance

SVG icons are widely used for sharp, scalable graphics, but poorly optimized files can slow page loads, cause layout shifts, and trigger rendering jank. The guide explains that SVGs are XML text files, so they often carry unnecessary editor metadata, verbose IDs, hidden layers, and excess decimal precision inherited from design tools like Figma, Sketch, or Illustrator. It recommends cleaning these up manually or with automated tools such as SVGO, which can be configured via plugins to strip metadata, simplify paths, and remove unneeded dimensions. For icon libraries, the article suggests integrating SVGO into the build process, for example through a Node.js script that processes every file in an icon directory.
