    Is It Still Worth Learning to Code in an AI World?

    Learning to code is still valuable in an AI world as it builds computational thinking, strengthens problem-solving skills, and equips individuals to shape and contribute to digital spaces. AI tools are evolving to augment rather than replace programming roles, with skilled developers needed to review and debug AI-generated code. Developing deep technical knowledge remains crucial amidst these technological advances.

    10 Remote Development Best Practices

    Remote development involves running development environments on remote infrastructure rather than local machines. Key best practices include avoiding pixel-streaming solutions like RDP/VNC, implementing offline-capable clients, using enterprise-grade orchestration platforms, adopting short-lived disposable environments, enforcing zero-trust security, and monitoring meaningful metrics. Modern solutions like CodeCanvas, GitHub Codespaces, and Gitpod provide automated provisioning, cost control, and security features that manual SSH setups cannot match. AI agent support is becoming essential for future-proofing remote development workflows.

    CLion Is Now Free for Non-Commercial Use

    CLion, a JetBrains IDE for C and C++ development, is now available free for non-commercial use. This initiative is in line with similar changes made to other JetBrains IDEs to support learners, hobbyists, and open-source contributors. The full IDE features remain accessible under this license with the exception of the 'Code With Me' feature. Non-commercial use includes learning and hobby projects, but a commercial license is still needed for commercial projects.

    A Farewell to Consoles

    DataGrip 2025.3 replaces query consoles with query files to improve workflow consistency. The change addresses longstanding issues where consoles lived outside project structure, were hard to find, and had limited context switching capabilities. Query files are now stored in a visible project folder, support full file operations, and maintain database context with improved visual indicators. Existing consoles will be migrated automatically with a one-release transition period.

    Query Consoles Are Coming Back

    JetBrains is reverting a controversial workflow change in DataGrip 2025.3 that replaced query consoles with query files. The redesign caused issues with global data sources and disrupted user workflows. Version 2025.3.1, releasing this week, will restore the original query console behavior. Users who created query files during the migration can delete them, convert them to consoles, or keep them for a planned improved workflow early next year. The team acknowledges failing their zero-regression standard and commits to more careful, flexible updates going forward.

    IntelliJ IDEA Moves to the Unified Distribution

    JetBrains is consolidating IntelliJ IDEA into a single unified distribution, replacing separate Community and Ultimate editions. The transition includes three phases: enabling GitHub builds with CI/CD pipelines, implementing graceful license expiration (users retain basic functionality when subscriptions expire), and migrating to one installer by 2025.3. The unified version will include more free features than current Community Edition, such as enhanced syntax highlighting for frameworks like Spring and Quarkus, project setup wizards, and basic database schema exploration. Ultimate features still require subscription but can be tried with one-click trials. Open source commitment remains strong with GitHub builds containing only open-source components, while the unified distribution includes some proprietary features available for free.

    Is Golang Still Growing? Go Language Popularity Trends in 2024

    Go, or Golang, remains a relevant and widely-used programming language in 2024, especially in cloud-native applications, infrastructure as code, and web services. With an estimated 5.8 million developers, it's evident that Go's usage has grown, driven by its strengths in performance, scalability, and ease of use for cloud applications. The language stands firm despite the rise of Rust, complementing rather than competing with it. The Go community continues to expand, with significant adoption in AI model serving. The leadership change in the Go team emphasizes stability and advanced focus areas such as cloud and AI.
