Vue apps can use TypeScript 7 now by ditching .vue files for TSX

·1 views

TypeScript 7, featuring a Go-native compiler with significantly faster performance, was released this week on npm. The official announcement warned that tools like Volar, which power Vue, Svelte, and Astro language services, cannot yet leverage the new compiler. However, a developer writing for DEV Community explains that their Vue application has been running on TypeScript 7 since launch by using .tsx files instead of the traditional .vue single-file component format. This approach bypasses the need for a custom language service layer, allowing Vue's reactivity and component model to work within standard TypeScript tooling. The author notes the migration was originally motivated by cleaner code and simpler tooling, with the TypeScript 7 speed benefit arriving as an unplanned bonus.

Eastern Europe's tech economies grow as Germany shifts IT investment eastward

Eastern Europe's tech markets are rapidly expanding and increasingly attracting German investment, with each country offering a distinct profile. Poland leads the region with an IT market worth around €15 billion and nearly half a million sector workers, while the Czech Republic targets €24 billion in ICT revenue by 2026. Hungary draws investors with a 9% corporate tax rate and above-average cloud adoption, and Romania is the fastest-growing market, projecting IT service exports to reach €44.8 billion by 2028. A shortage of 124,000 IT professionals in Germany is accelerating nearshoring to Eastern Europe, where over 1.3 million developers are available at an estimated 40–70% cost saving per employee. Shared service centres in the region are also evolving beyond back-office functions into high-value Global Business Services, handling analytics, consulting, and R&D for major Western clients.

CS Student Explains How He Uses AI Tools to Tackle Mandatory Writing Assignments

A computer science sophomore describes relying on AI writing tools to complete technical writing assignments, which he finds misaligned with his logic-oriented thinking. He argues the practice is a practical time-management choice, comparable to using Stack Overflow for debugging rather than an ethical compromise. His key finding is that generic AI prompts produce poor results for CS courses, since professors expect students to engage with specific class frameworks and content. To counter this, he developed a "context dump" method, feeding the AI assignment instructions, lecture notes, readings, and personal bullet points before generating a draft. He estimates this preparation takes 20–30 minutes per major assignment, which he considers far more efficient than writing from scratch while yielding course-relevant output.

AEO vs SEO: Why Letting AI Bots Crawl Your Site Matters in 2026

Answer Engine Optimization (AEO) is emerging as a distinct discipline from traditional SEO, focused on ensuring content is indexed by AI platforms like ChatGPT, Claude, and Perplexity rather than just Google. Each major AI provider operates multiple functionally separate crawlers — for training, search indexing, and live fetching — meaning a single robots.txt rule blocking one bot does not block the others. Website owners must make granular, per-bot decisions in their robots.txt files to control which AI behaviors they opt into or out of. While major players like OpenAI and Anthropic generally honor robots.txt directives, the protocol carries no legal weight and some crawlers, including those linked to Perplexity, have been documented evading such rules entirely. For reliable enforcement against non-compliant bots, server- or CDN-level firewall rules are necessary rather than relying solely on the robots.txt text file.

Wearable Health Data Offers Little Clinical Value While Raising Privacy Risks

Smartwatches, rings, and patches now collect vast amounts of biometric data, but surveys suggest only 9% of healthcare professionals find more than 75% of it useful in daily practice. Doctors often struggle to interpret the flood of metrics patients bring to appointments, as the data lacks the context and filtering needed for meaningful clinical decisions. Despite limited medical utility, consumer wearable data is largely unprotected by HIPAA, leaving it accessible to insurers who can use it to adjust premiums before any health benefits reach users. This asymmetry — where companies and insurers profit from data while patients wait for medical value — raises serious fairness concerns. Additionally, gamification features designed to encourage healthy habits can foster obsessive behaviors, as illustrated by cases where users prioritize maintaining streaks over their own wellbeing.
