Let's hope so.

HumbleBee is out: a local-first open source time tracker with CLI + GUI.

It started after a canceled flight in San Francisco and a night at the airport, when I began using AI to learn Go faster.

I hate Slack.
It’s a mess.
Mails are much better.
I know how old this makes me sound.

I will never understand why people prefer Claude Code over Codex.

Codex never “made up version numbers.”
And it never told me to reverse-engineer anything, instead of using the ready-to-use Docker containers.

I started buying physical books again last year.
Nobody can take them away from me.
Unless they send the firemen from Fahrenheit 451.

Jack London’s The Sea-Wolf asked:
What is a human being worth when power has no conscience?
I ask again.
What remains human when value becomes a calculation?

Blue Origin is seeking U.S. Federal Communications Commission approval to operate a 51,600-satellite "orbital data center" network. Today, the Center for Space Environmentalism officially filed our opposition to its application.

We're demanding a rigorous environmental review to assess collision risks and the severe threat to our shared night sky before any approval is granted. Read our comment in full: https://www.spaceenvironmentalism.org/actions/public-statements-and-comments/blue-origin-comment-april-2026

Java Logging - Christian Grobmeier

Logging is a must-know skill for Java developers. Logging is the art of making things visible—and when your codebase crashes at 5PM Friday you’ll want all the data you can get about your application! Java Logging introduces and expands the logging skills every developer needs to master. For newer coders, everything is explained from the ground up in clear, accessible language. For the old hands, this is a chance to catch up with the state of the art in tools and techniques, including Log4j2! In Java Logging you’ll learn: Reading and analyzing log files The key components of standard logging systems Writing good and useful logging code Integrating multiple logging tools into your workflow Logging lets you monitor your software for unexpected behavior, spot slowdowns and areas for performance tuning, easily audit for compliance and—most important of all—makes it easier to debug when things go wrong. Your expert guide in Java Logging is Christian Grobmeier, logging veteran and current maintainer of Apache Log4j. Through stories of experience, hands-on examples, and important tips, Christian shows you how to create the kind of logs that you (and your colleagues) will be thankful for.
