Why redis is losing friends and valkey is gaining them

  • Redis, once a beloved in-memory data store, is now facing backlash due to a controversial change in licensing from the permissive BSD license to the SSPL, prompting major Linux distros like Debian, Fedora, Alpine, and openSUSE to drop Redis from their repositories.
  • This licensing shift by Redis Labs has caused concern among developers, distro maintainers, and cloud providers, leading to legal uncertainty and a loss of trust in the reliability of Redis for deployment.
  • In response to this, Valkey emerged as a community-driven drop-in replacement for Redis, maintaining the old-school BSD 3-Clause license and garnering support from the Linux Foundation for stability and transparency.
  • Valkey aims to provide a reliable alternative to Redis without the legal complications, gaining traction among developers and even catching the attention of cloud providers like UpCloud, which now supports Valkey as a core service.
  • While Redis still holds recognition for its performance and ecosystem, Valkey stands out for its commitment to trust, openness, and transparency, leading developers to consider making the switch for long-term benefits.
  • The shift towards Valkey signifies a broader trend of developers becoming more license-savvy and emphasizing governance and openness in software choice, indicating a potential future where trust carries more weight than legacy brand recognition.
  • With Valkey gaining ground and developers increasingly focusing on trust and community-driven projects, the story highlights the importance of not just evaluating code performance but also considering the governance and licensing behind the software.
  • Amidst the evolving landscape of in-memory databases and open-source licensing, the focus on trust and community values is reshaping software adoption decisions, with forks like Valkey offering a principled alternative to established but controversial choices like Redis.
  • As the industry navigates the implications of open-core licensing and the power of developer communities, the shift towards projects like Valkey serves as a reminder to prioritize trust in both the code and the people behind the software.
  • In a world where trust and governance play significant roles in software selection, Valkey represents a move towards more transparent, community-driven alternatives in response to licensing changes that challenge the foundational principles of open source.
  • The emergence of Valkey stands as a testament to the importance of trust, governance, and transparency in software choices, signaling a shift towards community-backed, license-conscious solutions over legacy options like Redis.

Why every dev needs a coding journal no, your memory isn’t enough

  • Keeping a coding journal is essential as your brain is not optimized for storage but problem-solving.
  • Logging daily wins, blockers, decisions made, command-line spells, and things you had to Google can help improve your coding journey.
  • Tools like VS Code with Git, Obsidian, plain text with cron, or jrnl CLI can assist in journaling effectively.
  • Journaling helps developers debug their thinking, gain clarity in complexity, and build a knowledge graph of their own brain.
  • Senior developers also benefit from journaling, as it helps track architectural decisions, provide leadership receipts, and enhance growth.
  • Building a journaling habit involves starting small, stacking it with existing rituals, using templates, automating reminders, and making it fun.
  • A coding journal is a survival tool that improves memory, debugs thinking, tracks growth, manages burnout, and enhances collaboration and mentorship.
  • Journaling is not just for productivity but for becoming a better developer and teammate by documenting your coding journey.
  • The best devs don't just ship code; they log the journey, and a coding journal is a testament to one's dedication to self-improvement.
  • Documenting your coding journey can be simple and rewarding, leading to improved problem-solving skills and overall growth as a developer.
  • Try journaling for 7 days, even with just one entry a day, to experience the benefits firsthand and become a more effective developer.
