Advanced URL Rewriting with Apache APISIX
I spoke at Swiss PgDay in Switzerland in late June. The talk was about how to create a no-code API with the famous PostgreSQL database, the related PostgREST, and Apache APISIX, of course. I already wrote about the idea in a previous post. However, I wanted to improve it, if only slightly. PostgREST offers a powerful SELECT mechanism. To list …

Structured Concurrency is More Than ShutdownOnFailure
Since Java 21, structured concurrency has been added as a preview feature. Structured concurrency is a way to manage sub-tasks that are run in parallel within a given scope. If you’ve ever seen a presentation about structured concurrency, you’ve probably seen the use of the ShutdownOnSuccess or ShutdownOnFailure classes.These classes will stop the scope and the still running sub-tasks within …

However, library developers are occasionally required to manipulate memory outside the heap for performance or specific use cases. This is where the controversial sun.misc.Unsafe comes in. While undeniably powerful, sun.misc.Unsafe is a double-edged sword. …

Depending on your tech stack, you must search for an existing library or roll up your sleeves. For example, Rust offers such an out-of-the-box …

The age-long method to achieve it is watermarking: A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as audio, video or image data. …
