  • Story Type: News Story
Every so often, I need to do some calculations related to dates. A few days ago, a colleague asked me to set up a new project definition in our (open source, of course!) project management system. This project is to start on the 1st of August and finish on the 31st of December. The service to be provided is budgeted at 10 hours per week. So, yeah, I had to figure out how many weeks between 2021-08-01 and 2021-12-31 inclusive. This is the perfect sort of problem to solve with a tiny Groovy script. read more

Use this open source tool for automated unit testing

  • Opensource.com (Posted by bob on Aug 25, 2021 7:56 PM EST)
  • Story Type: News Story
Modernizing and transforming legacy applications is a challenging activity that involves several tasks. One of the key tasks is validating that the modernized application preserves the functionality of the legacy application. Unfortunately, this can be tedious and hard to perform. Legacy applications often do not have automated test cases, or, if available, test coverage might be inadequate, both in general and specifically for covering modernization-related changes. A poorly maintained test suite might also contain many obsolete tests (accumulated over time as the application evolved). read more

Access your iPhone on Linux with this open source tool

  • Opensource.com; By Don Watkins (Posted by bob on Aug 23, 2021 9:58 PM EST)
  • Story Type: Tutorial; Groups: Linux, Mobile
