A Concise Overview of Java’s Instant, LocalDateTime, ZonedDateTime and When to Use Which

Leider ist der Eintrag nur auf English verfügbar.The authoritative answer to a question on Stack Overflow on the difference between Instant and LocalDateTime covers various classes from the Java 8 Date/Time API and how those are actually meant to be used. Names such as LocalDateTime can be misleading in that they suggest a specific locale or locality rather than any locality (as that name is intended). This, in turn, can give rise to problems with inaccurate date and time values if timezones ...

Automating Processes: Meeting Notes

Leider ist der Eintrag nur auf English verfügbar.One of the key benefits of business software, or as a matter of fact, any software, is automation of tedious, repetitive tasks. One of the three great virtues of a programmer according to Perl creator Larry Wall is laziness as defined in: "The quality that makes you go to great effort to reduce overall energy expenditure. It makes you write labor-saving programs that other people will find useful and document what you wrote so ...

Keeping a Record of Software Architecture Decisions

Leider ist der Eintrag nur auf English verfügbar.The need for asynchronous communication in organisations has become particularly obvious since 2020, when remote work and distributed work environments rapidly became the default setting for knowledge workers. Asynchronous communication essentially means that instead of exclusively communicating objectives, goals and the way by which to achieve them in-person (i.e. synchronously with everyone involved present at the same time - whether on-site or in a virtual space such as Slack or Zoom) we try and keep ...

Working Across Timezones in Remote Work Settings and Distributed Environments

Leider ist der Eintrag nur auf English verfügbar.When working in a distributed environment or remote work environment, as is increasingly - and quite fortunately - becoming the default for knowledge workers, and the software industry in particular, chances are, rather sooner than later you'll be collaborating across timezones. I'm currently collaborating with people from EDT, GMT, CEST, MYT, JST, and AEST timezones, for instance. Asynchronous communication is crucial in a remote work setting already when no time differences are involved. It becomes absolutely ...

Blogumentation Revisited

Leider ist der Eintrag nur auf English verfügbar.Some time ago I wrote about a process called "blogumentation": Derived from the insight that arguably the best way to learn something and to internalise knowledge is to write about it and to try and explain that knowledge to others, blogumentation essentially means writing about a subject matter (e.g. a solution to a particular programming problem or a new practice you've just learned about) that you consider worth documenting and publishing the result. It means ...

CORS: What It Is and How It Works

Leider ist der Eintrag nur auf English verfügbar.Expanding on last week's article on best practices for REST API Design I'd like to point to a specific aspect working REST APIs frequently entails: A browser security feature called "Cross-Origin Resource Sharing (CORS)". This feature allows you to define which resources provided by a web application are supposed to be accessible from which origin, which in turn typically is comprised of protocol, host / domain name and port. This website's origin for example is ...

REST API Design: Best Practices

Leider ist der Eintrag nur auf English verfügbar.It's probably safe to say that REST (REpresentational State Transfer - originally described by Roy Fielding) is the most widely used architectural pattern when it comes to APIs in web application contexts. From statelessness, to self-descriptive messages, and hypermedia as the engine of application state (HATEOAS) REST comes with quite a few principles, constraints, patterns, and flavours, not all of which are used or applied consistently with each REST API. REST often is a rather ...
