Enhance the switch construct so that exceptions thrown by the selector (the e in switch (e) ... ) can be handled in the switch block. Alongside a previous enhancement to handle null selectors, this makes switch even more useful for pattern matching. This is a preview language feature .
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
In Python as in other programming languages, this grand principle encourages software architects to escape from Object Orientation and enjoy the simpler practices of Object Based programming instead.
I set out to find a simple definition that would help managers frame the fundamental things they expect from software engineers.
The following image is a "sneak peek" at the full implementation and the resultant system:
Master Git through understanding, not memorization. Learn branches, merges, and collaboration with clear explanations and visual diagrams.
This is a story about Imagebin. Imagebin is the longest-lived software project that I still maintain. I'm the only user. I use it to host images, mainly to include in my blog, sometimes for sharing in other places. Imagebin's oldest changelog entry is dated May 2010, but I know it had already existed for about a year…
Summary In this post I’ll go into detail about how, during my contracting work for Shimmer Industries (a company founded by Eskil Steenberg which is focused on developing a real-time lighting designing software), I worked on a piece of software which enabled us to use the MacOS and iOS APIs using a custom C API…
Welcome again HN! Dark [https://darklang.com] is a programming language, structured editor, and infrastructure—all in one—whose goal is to make it 100x easier to build backend services.

One of the things I like to do is compare how different languages solve the same problem — especially when they end up having very different approaches. It’s always educational. In this case, a bunch of us have been working hard on trying to get reflection — a really transformative language feature — into C++26…
If this isn’t a Zawinski quote, it should be. I have avoided the JVM my entire life. I am presently confronted with problems which fit in the JVM; JVM libraries, concurrency, giant data: all …
I’m often surprised how long software can keep trying to use compatibility features ages after their best-by date. Now that GCC 4.8 builds on Tige...
Crystal has gone a long way since we started it over five years ago. What was once an experiment to see if it was possible to have a compiled yet Ruby-like language, is now a trending language with over 7,000 GitHub stargazers and almost 1,400 shards. Its popularity has risen considerably in the last few years, and we…
Specify UTF-8 as the default charset of the standard Java APIs. With this change, APIs that depend upon the default charset will behave consistently across all implementations, operating systems, locales, and configurations.
It's not very obvious how to optimize react applications that use Redux. But it's actually fairly straightforward. Here's a short guide, along with a few examples.
“A good programmer is someone who looks both ways before crossing a one-way street.” – Doug Linder
This is a post about performance. Most of the time when worrying about the performance of a piece of code the overwhelming advice should be (with apologies to Brendan Gregg) don’t worry about it, yet. However there is one area where I counsel developers to think about the performance implications of a design, and that…
A long time ago, I wrote a memoization library for Ruby. It was not easy, but I learned a great deal in the process. In this article, I am share these learnings and showing you how deep the memoization rabbit hole goes.
Several JavaScript data structures such as Map, Set, WeakSet, and WeakMap use hash tables under the hood. This article explains how V8 v6.3 improves hash table performance.
In this post I will unfold my understanding of what makes a tech team competent in 4 levels with 6 main criteria and 25 sub criteria.
I think that all other considerations are of the extrinsic real-world kind – domain modeling, usability, schedules, platforms, etc. I also think that I can show how any "good" programming practice is mainly aimed at minimizing redundancy, dependencies, or both. I even think that you can tell a "good" programmer from a…
Pivotal ends sponsorship for Groovy & Grails; these popular JVM projects now seek new funding and partners to continue their vital development.
