The Leprechauns of Software Engineering

After having read a summary of the book, I want to read it again!

Valkey 8.1’s Performance Gains Disrupt In-Memory Databases

Good news for all Valkey users.

I’m a bit surprised that the author mentions "disgruntled developers forked a new project, Valkey". That’s a very interesting way to spin it.

Let’s face it: cloud providers make millions by shrink-wrapping existing Open Source software. As with Elasticsearch and Terraform before, they got scared about the license change and decided to fork it, using the Linux Foundation for that.

Spring News Roundup: Milestone Releases of Boot, Security, Auth Server, GraphQL, Integration, AMQP

I was aware of Michael Redlich’s Java News Roundup on InfoQ, but it’s the first time I stumble upon his Spring News Roundup. He publishes it every month, and if you’re a Spring developers, you shouldn’t miss it!

Introducing content-visibility: auto - A Hidden Performance Gem

I left the realm of CSS a long time, and it’s always interesting to see it has evolved into its own private niche, which you need to be an expert of.

Calling MCP Servers the Hard Way

Great explanation of the MCP protocol for newbies; I learned a lot!

Growth at what cost? Balancing user experience and revenue

And now for something completely different: product management in the Open Source industry.

Google Zanzibar EXPLAINED in 5 Minutes
Exclusive: Google will develop the Android OS fully in private, and here’s why
  • Google has confirmed to Android Authority that development of the Android operating system will soon fully happen in private.
  • Currently, Google shares some of the work it does on the public AOSP Gerrit, but moving forward, this work will all be done in private.
  • The goal for this privatization is to simplify Android OS development and not to hinder external developers, which is why Google remains committed to publishing source code to AOSP after each release.

Software vendors have to switch to non Open Source licenses to avoid cloud vendors to eat their revenue: Open Source zealots cry foul. Google switch all development behind closed doors–nobody moves.

The double standard is real.

Book Summary – Leprechauns of Software Engineering by Laurent Bossavit

I’m very happy to see this book being (re-)discovered. It has been my inspiration more than fifteen years ago for my first conference in Ukraine.
