Oracle reveals the feature roadmap for JDK 28, a non-LTS release due March 2027, including value objects, generational Shenandoah GC, strictly initialized fields, a standard JSON API, PEM encoding for crypto objects, and ahead-of-time compilation to cut startup time.
The author argues that schools teach harmful C++ habits like omitting braces, declaring variables at function tops, and skipping initialization, while overemphasizing rarely-used algorithms over real projects, delaying hands-on coding for years, and prioritizing theoretical coursework over skill-building projects like game clones that develop practical expertise.
FreeBSD release engineering lead Colin Percival announces a new Amazon Machine Image with KDE Plasma desktop, Chromium, and LibreOffice pre-installed, accessible via RDP on AWS EC2, designed to mimic Windows behavior and available on the AWS free tier, though the AWS console currently misidentifies RDP support.
The author benchmarks MariaDB 10.3, MySQL 8.0, and PostgreSQL 12 using a real Turkish motorcycle classifieds app with many simple queries, finding MariaDB 5% faster on average and 7% faster at p95 with lower CPU usage, though MySQL handles tail latency better and memory differences stem from default performance_schema settings.
This article reviews Kate, a free, open-source, lightweight IDE from KDE, comparing it to VS Code; it highlights Kate's fast startup, built-in terminal, LSP-based code completion for 200+ languages, and four core plugins, but notes its lack of external plugin support and advanced debugging, making it ideal for beginners and intermediate developers on modest hardware.
India's software services industry grew 9.5% to $239.3 billion in FY 2025-26, driven by strong US and UK demand, while software product development declined; RBI survey data shows AI-driven revenue deflation predicted by tech giants has not yet materialized.
Python 3.15 introduces seven major features including lazy imports for faster startup, built-in frozendict for immutable mappings, sentinel objects to replace None checks, an upgraded JIT compiler delivering 8-13% speedups, clearer error messages with cross-language method suggestions, and a rollback of the incremental garbage collector due to memory overhead.
React Native finishes its six-year architectural overhaul with 80% adoption, yet Shopify abandons it for native Swift/Kotlin, using AI agents to rewrite its app in 12 weeks with 6 engineers, achieving 45% faster cold starts and 62% less stutter—proving AI has upended the cross-platform cost equation.
Anthropic's Claude Code now supports OpenAI's AGENTS.md format, enabling a single configuration file to work across multiple AI coding assistants like Codex and Claude Code, eliminating duplicate maintenance while maintaining backward compatibility with CLAUDE.md.
PHP 8.6 introduces StreamErrorMode, StreamError objects, and stream_last_errors() to provide typed error codes for stream operations, replacing fragile warning string parsing. It details three context options, exception and silent modes, StreamException with StreamErrorCode enum (70+ cases), handling multiple errors, new context parameters for four functions, and backward compatibility.
