Last week, I described a use-case for a custom Stream Collector. I received a intriguing comment on Twitter: There was a 'Moved Permanently' error fetching URL: 'https://twitter.com/Miguucm/status/1389258245886390292' Hats off to you, Miguel! Your comment revealed a method I didn’t know! So I decided to investigate…
Creating a full-fledged API requires resources, both time and money. You need to think about the model, the design, the REST principles, etc., without writing a single line of code. Most of the time, you don’t know whether it’s worth it: you’d like to offer a Minimum Viable Product and iterate from there. I want to…
This is the 3rd post in the My journey with Home Assistant focus series. I’m the happy owner of a couple of Philips Hue connected lights for a some years. Some of them are colored, some of them regular. In addition, I bought a sensor to go along with the light I installed in my toilets: it turns on automatically when…
In the good old days, applications were simple. A browser sent a request to a webapp endpoint; the latter fetched data from a database and returned the response. The rise of mobile clients and integrations with other apps upset this simplicity. I want to discuss one solution to handle the complexity in this post. The…
Every now and then, there’s a post predicting the death of the Java language. The funny thing is that none of them writes about a date. But to be honest, they are all probably true. This is the fate of every language: to disappear into oblivion - or more precisely to be used less and less for new projects.
When I started my career, XML was ubiquitous. The meta-information in a Java JAR file - the manifest - follows a proprietary format. But Java EE designers built it from the ground up on XML: meta-information of all artifacts is in XML format e.g. web.xml, ejb-jar.xml, application.xml, etc. Java EE is one example I…
This is the 6th post in the The state of JVM desktop frameworks focus series.
Last week was the release of Oracle’s GraalVM. As stated on the website: GraalVM is a universal virtual machine for running applications written in JavaScript, Python 3, Ruby, R, JVM-based languages like Java, Scala, Kotlin, and LLVM-based languages such as C and C++. GraalVM removes the isolation between programming…
This is the 6th post in the Learning Clojure focus series. In general, one learns by comparing to what one already knows: I’m learning Clojure in that way. Coming from a Java background, I naturally want to use streaming features. So, what would be the Clojure counterparts of Java’s functions filter(), map(), etc.?
I recently watched GOTO conferences' talk Calling Functions Across Languages by Richard Feldman. I’m afraid I have to disagree with using the term 'language' in this context. It’s a no-brainer to call Java from Kotlin or Scala or to call Java from Kotlin. Hence, in the rest, I’ll use 'stack'.
