Developer Builds Browser-Based Tool That Auto-Repairs Broken JSON Syntax

0
·1 views

A developer has released JSON Auto-Fix, a free client-side tool designed to automatically detect and repair common JSON syntax errors without requiring a server upload or account registration. The tool addresses frequent issues such as missing commas, unquoted keys, single quotes, trailing commas, and unclosed brackets through a multi-pass correction algorithm. It also handles typographic or smart quotes that appear when JSON is copied from sources like Word documents, Slack, or PDFs. If the input is too malformed to fully repair, the tool reports which fixes were applied and where parsing still fails. The tool is part of a broader free suite at jsonsuit.com that includes a formatter, a diff comparator, a JSON-to-TypeScript converter, a JWT decoder, and a JSONPath query tool.

Qwen2.5-Coder Edges DeepSeek-Coder in Local Solidity Security Reviews at 7B Scale

A developer tested Qwen2.5-Coder and DeepSeek-Coder locally via Ollama on WSL2, running both 7B-and-below models against ten small Solidity contracts containing deliberately planted security bugs. Each contract was evaluated using three prompt types — open-ended, targeted, and structured — with results scored manually on bug detection, accuracy, and output noise. Qwen2.5-Coder showed a clear advantage in instruction-following, consistently respecting structured output formats critical for automated pipelines. While DeepSeek-Coder matched Qwen on detecting classic vulnerabilities, it more frequently drifted off-topic and produced generic explanations rather than specific attack sequences. The author notes the comparison was motivated by model selection for an open-source auditing tool and cautions that neither model is suited for large, real-world contract audits.

React challenger Octane debuts; TanStack drops RSC; npm to scan for malware at publish

Octane, a new framework from former React and Svelte contributor Dominic Gannaway, compiles React's programming model — including Hooks, Suspense, and Actions — ahead of time, eliminating the Virtual DOM and manual dependency arrays. The project launches with built-in integrations for TanStack, React Three Fiber, and other popular libraries. TanStack has moved its website away from React Server Components, instead adopting SSR alongside two new lightweight packages, TanStack Markdown and TanStack Highlight, to improve performance. npm announced it will begin scanning packages for malware at publish time, adding a new layer of supply-chain security. Additionally, several JavaScript proposals advanced at a recent TC39 meeting, and Core Web Vitals will now measure soft navigations in single-page applications.

GitHub Achieves 45 GiB/s Case-Folding Speed in Code Search Using Branch-Free Logic

GitHub engineers have developed a high-performance technique to case-fold source code during search operations, achieving speeds exceeding 45 GiB/s on a single CPU core. The approach relies on a branch-free loop design combined with byte-space arithmetic, eliminating costly conditional checks that typically slow down text processing. Case-folding is essential for case-insensitive code search, requiring every byte of indexed source code to be transformed efficiently. By avoiding early exits in the processing loop, the implementation maintains consistent throughput close to the theoretical memory bandwidth limit. GitHub detailed the technique on its engineering blog, highlighting it as a key optimization powering its code search infrastructure.
