Page blanche ou erreur critique : deux pannes WordPress, deux façons de les diagnostiquer

·2 views

Le terme « page blanche » recouvre aujourd'hui des situations différentes, car la plupart des écrans affichent un message plutôt qu'un vide. Depuis WordPress 5.2, un gestionnaire d'erreurs fatales intercepte les crashs d'extensions ou de thèmes et affiche une alerte, ce qui indique que le démarrage a réussi. Le fichier fautif et la ligne concernée apparaissent alors dans wp-content/debug.log, lorsque ce journal est activé. Une page réellement vide signale une erreur survenue avant l'initialisation de WordPress, souvent une erreur de syntaxe dans wp-config.php. Dans ce cas, le diagnostic se fait dans le journal d'erreurs PHP fourni par l'hébergeur.

Anthropic Launches Claude Duet, a Lightweight Chat Model for Engineers

Anthropic has released Claude Duet, a smaller chat-optimized language model designed to run on a single GPU and accessible through a public HTTP API. Positioned as a coding co-pilot, it targets interactive assistance, data exploration, and low-latency inference rather than the heavier tasks of its larger Claude 3 sibling. The article highlights lower inference costs, since a roughly 7 billion parameter model fits in 16 GB of VRAM, along with reported response times under 300 milliseconds for 512-token prompts on a V100 GPU. It also notes that the API uses the same JSON schema as Claude 3, allowing existing tooling to be reused with minimal changes. The author walks through a sample setup that deploys a GitHub issue summarizer in Kubernetes using the official Python client.

Autonomous AI Agents Can Use Gas-Sponsored Transactions on Base L2 via ERC-4337

A DEV Community article argues that autonomous AI agents often fail in production because they hold private keys with native gas balances, which creates both operational stoppages and security risks. It proposes ERC-4337 Account Abstraction on Base L2 as a fix, separating transaction authority from gas payment through a Paymaster contract. Under this model, agents submit UserOperations that a Paymaster sponsors, letting them act onchain without holding ETH while treasury rules limit which transactions get covered. The piece includes a Python example that constructs, sponsors, and signs such an operation targeting a designated treasury address.

Developer builds 59 free browser-based dev tools in vanilla JS with no server or tracking

A developer has created Antigravity Tools, a collection of 59 free utilities for programmers that run entirely in the browser. The project was built with no dependencies, no backend server, and no telemetry, so user data never leaves the device. Its tools rely only on native browser APIs such as Web Crypto, Canvas, Web Audio, and IndexedDB. The collection covers areas like JWT decoding, key generation, PII masking, encoding, AI token cost estimation, JSON conversion, regex testing, and cron building. The author shares the project and the lessons learned while developing it.
