I searched a half hour for a how-to for Let’s Encrypt Wildcard certificates with automatic renewal. All sites I’ve found just promoted the manual method, where I would have to manually add dns entries every 3 months – neeeeeever! Then I stumbled upon acme.sh.

When I did and wrote the first post I did not know of ddrescue. And it worked like a walk in the park, it just took eight and a half hours… /tmp # ddrescue -d -r3 /dev/sdd2 blah.img blah.logfile GNU ddrescue 1.21 Press Ctrl-C to interrupt ipos: 113173 MB, non-trimmed: 0 B, current rate: 0 B/s […]
I were a long-time Firefox user because of the unique addon called ‘tree style tabs’ and this browser is still the only one implementing this feature the right way. Basically there’s no alternative, period. So now I’m facing the problem that Firefox gets slower and slower. First of course I’m a tab whore, 50-100 tabs […]
Just using my blog as my permanent public notepad. def my_keys = build_result.keySet() as List; for (int i = 0; i < my_keys.size(); ++i) { def key_to_unstash = my_keys[i]; print ‘Unstashing ‘ + key_to_unstash; unstash “${key_to_unstash}”; } my_keys = test_result.keySet() as List; for (int i = 0; i < my_keys.size(); ++i) { def key_to_unstash = […]
