my blog. for you.

Let’s talk digital.

I’m an independent IT consultant and entrepreneur in the Internet and software business. I’m interested in design, enterprise applications, web apps and SaaS products. I design and develop business solutions and applications. I help companies in terms of software quality and knowledge transfer, e.g. with Angular and Spring Boot.

GitLive – Real-time Code Collaboration

Continuing on last week's subject of better collaboration and knowledge sharing in software development (with CodeStream, in that case) I'd like to share GitLive - a new, promising tool I've come across. GitLive allows you and your fellow team members to collaborate on code in real time right in your IDE thereby turning it "into a collaborative space". What I've seen so far looks intriguing. I think that we'll be moving into that direction more rapidly and that we'll see more tools of ... Read more

CodeStream – Code as a Knowledge Base

CodeStream is a code review tool that allows you to conduct such reviews right in your IDE, i.e. without changing context. According to their master plan CodeStream is supposed to "Provide the ability to talk about any block of code, on any branch, in any state [...]" "Eliminate context switching costs [...]" "Treat codeblocks as a first-class object [...]" in order to allow developers, both new and senior ones, to quickly get up to speed with an existing codebase and to collaborate and draw upon each ...

sdras/awesome-actions: A Curated List of Useful GitHub Actions

As a follow-up to last week's post on automating software maintenance tasks with GitHub Actions I'd like to point you to Awesome Actions, a curated list of resources related to GitHub Actions. The list includes both predefined actions you can directly use and resources for getting started with building your own actions and workflows, as well as various utilities for testing, linting and security purposes.

Using GitHub Actions for Automating Angular Updates

I've published quite a few Angular applications under various open source (MIT and Apache License, respectively) licenses : GDPR Transparency PivotHelper TimeSheets3 Among other responsibilities, maintaining software comes with the task of regularly checking for dependency updates and applying them to the software in question. This first and foremost involves security updates but also bug fixes and new features for the frameworks and libraries used by the application. Fortunately, Angular CLI comes with a command that allows you to do just that: ng update However, while having a ... Read more

The Mother of All Leaky Abstractions: The 500-mile Email

In last week's musings I complained about leaky abstraction on two counts, which reminded me of what in my opinion must be the mother of all leaky abstractions: The notorious 500-mile email. Impedance mismatches and TCP connections seeping through the cracks of the latest reactive programming frameworks certainly at times are difficult to deal with but the actual underlying transmission protocol of the relativistic universe shining through when trying to send an email? It can't get any better than that ... Read more

Musings of a Greybeard on the State of Software Engineering

Two days ago software engineer and fellow blogger Tom Hombergs asked on Twitter if software development had grown harder over recent years, to which I replied: "Incoherent ramblings of a greybeard (without a beard, which is weird; these words rhyme, which is even weirder ...), who has seen at least 3 fat-client-thin-client cycles (the standard time unit in software architecture): As usual it depends. Just a few examples:" For the purpose of this blog post I just deemed it more sophisticated to call ... Read more

German COVID-19 Tracing App Available Now

Earlier today, the highly anticipated COVID-19 tracing app for Germany, called Corona-Warn-App, has been released. The iOS version is available on the App Store. The Android version can be downloaded at Google Play. The Corona-Warn-App is based on the DP3T (Decentralized Privacy-Preserving Proximity Tracing) architecture and the joint specification by Apple and Google for privacy-preserving exposure notification, which implements this architecture as an API for official public health providers to draw upon. The app is developed and published as open source under the Apache ... Read more

Don’t Just Document Software, Tell a Story.

Humans tend to remember stories much better than mere facts, which probably is why storytelling has such a long tradition in human history. Storyteller is - quoting from their own description - an "editor plugin that generates web pages that recreate and animate entire programming sessions" (see this playback repository for examples and the project's GitHub repository for more details). It's an interesting, novel take on software documentation in that instead of merely describing some current state of code and what it's supposed ... Read more

My name is Björn …

Looks like my name's broken. Perhaps next time I'll check in under a non-Unicode, strictly ASCII charset one. Does that count as a @KevlinHenney? — Björn Wilmsmann (@bwilmsmann) October 2, 2019 https://twitter.com/bwilmsmann/status/1179428788708560896 Read more
