First of all, I rarely print anything on paper and have gone months without using the printer. Secondly, though, I've set the printer to be shared over my home network, so I can send files to print from anywhere in the house. I didn't need any special equipment for this setup. It's accomplished with just my usual Linux computer and the Common Unix Printing System (CUPS).

Use this open source tool for automated unit testing

  • (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
