Two Hard Things in Computer Science

Leider ist der Eintrag nur auf English verfügbar.I've always liked Jeff Atwood's variation on Phil Karlton's original quote "There are only two hard things in Computer Science: cache invalidation and naming things.": There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors. However, with reactive programming these days this version by Dave Stagner probably is even more appropriate (especially since it uses zero-based numbering, which of course is the only decent way of indexing elements in a sequence ...

GitLive – Real-time Code Collaboration

Leider ist der Eintrag nur auf English verfügbar.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 ...

CodeStream – Code as a Knowledge Base

Leider ist der Eintrag nur auf English verfügbar.CodeStream is a code review tool that allows you to conduct such reviews right in your IDE, i.e. without changing context.

Using GitHub Actions for Automating Angular Updates

Leider ist der Eintrag nur auf English verfügbar.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.

Fetching Incoming Invoices in an Automated Fashion With Puppeteer

Leider ist der Eintrag nur auf English verfügbar.Like I said in 2016, accounting is still a manual and tedious process. However, since then I've made quite some headway, especially with regard to automatically fetching and storing incoming invoices.

One particular, lasting pet peeve of mine in that respect, however, so far has been ...
