Golang provides the
syscall/js experimental package to facilitate
transpiler; just targeting your official Go compiler to WebAssembly and loading
the artifact in the browser. This blog post is a simple tutorial to allow you
setting up your Go WebAssembly project, as well as some basic functions to
This blog post is a step-by-step guide that shows you the basic usage of
KAConf, an Annotation-based configuration system
inspired in the wonderful Spring Boot, but simpler, lighter,
not so magic, and independent of any large framework, with no transitive
In my previous blog post I evaluated the
feasibility of Java for lightweight system programming thanks to the
native image generation tool. Despite the initial results look promising,
I felt disappointed when they
pointed me out that GraalVM does not support reflection by default (which IMHO
is a wonderful and powerful tool to enhance the expressiveness of our software
and to reduce boilerplate). However, you can actually configure the
ahead-of-time compiler to incorporate a user-provided reflection metadata.
There is still a common belief about Java being slow (especially during the startup)
and memory-consuming, making it not being the first option for ephemeral service
instances, like containers. This blog post pretends to put some light on
those assertions, quantifying the impact of a last-generation JVM in a simple,
single-threaded, application. We compare the impact of the JVM measuring the
execution time and memory spent of a Java QuickSort implementation,
comparing it with the execution of a native image generated with the modern
GraalVM Ahead-Of-Time (AOT) compiler and the same
QuickSort implementation in Go.
After almost two years without updating this blog, I have changed the Markdown
processor from Blackfriday to
Goldmark, which includes an extension to highlight
the code syntax according to the Alec Thomas' Chroma engine and styles.
Despite copying a struct with several fields is slower than copying a pointer
to the same struct, returning a struct value may be faster than returning a
pointer if we consider escape analysis particularities.
This post briefly explains how the blog is organized, and how to create new posts and templates.
This is the first post of my great blog.
