This page is basically a summary of how you get around the disappointing fact that almost all git commands have no "dry-run" option. There are so many ways in which a pretty recently-developed set of tools such as git could be so much better if only the developers had thought about the shortcomings of the commands they were already familiar with, and picked out the be… text/html 2026-09-15T18:13:10+02:00 antony http://retinal.dehy.de/docs/doku.php?id=technotes&rev=1789488790&do=diff Many of the following articles contain some of my opinions. If you find you disagree with them, please feel free to publish your own. Some of what follows is also incomplete (occasionally the term "work in progress" is appropriate). I try to mention this at the start of any such article. All articles also have a "last modified" date at the bottom - you may wish to check this in case some of what I have written becomes out of date, simply due to the inexorable passage of time.

I think git is an unpleasantly inconsistent collection of tools and commands which disappointingly failed to learn from the disparate and sometimes conflicting options to other command-line utilities (for example, does -n mean "add line numbers to the … text/html 2026-09-14T22:40:47+02:00 antony http://retinal.dehy.de/docs/doku.php?id=technotes:qualcomm_gobi_1000&rev=1789418447&do=diff This device is available under a variety of Vendor names and models - one of the most common appears to be HP / Lenovo UN2400. I bought a couple on eBay as "HP / Dell / Qualcomm T77Z039.04 UMTS" cards for €5 each. If I could get them working, nice; if not, it's only €5.
