1715455 - Let's Encrypt: certificate lifetimes 90 days plus one second #letsencrypt, #certificate, #lifetime
Let’s Encrypt is well-known for issuing certificates that are valid for only 90 days. Since the very first certificates issued by Let’s Encrypt’s infrastructure, those certificates have been given a 90 day validity period by our CA software by taking the issuance time and adding exactly 2,160 hours to yield the certificate’s “not after” date. However, RFC 5280 defines the validity period of a certificate as being the duration between the “not before” and the “not after” timestamps, inclusive. This inclusivity means that Let’s Encrypt’s certificates have all been actually valid for 90 days plus 1 second.
Wow! What a good report. It really details all the important points and steps taken. I trust they know what they do.
How to end up with 500,000 commits in your log #story, #appdev
I once worked for a company where they managed to create about half a million subversion commits in just 2 or 3 years, with about 3 developers working on it. I’ll leave it as an exercise to guess how they managed to do that :-)
It's always fun to read such stories. Sometimes unbelievable that something like that can even be true.

Firefox Hardening Guide | BlackGNU #firefox, #hardening
There are various similar guides on other sites, but many of these guides were partially incomplete, so I’ve tried to write the most complete guide as possible, which can be used by paranoid users like me.
I haven't followed the guide yet, it's on my todo list now.
Brave, the false sensation of privacy | BlackGNU #browser, #privacy, #observation
Brave is a chromium based browser, which comes with a built-in adblocker and with a “rewards” program, that is supposed to make you earn money. But the relevant part today is that Brave is advertised as a “private browser by default”.
It's not clear how much is true. But I would anyways not use such a browser. The only one I ever trust is Firefox.

[German] Netzbasteln: Universelle Fernseh-Ausschalt-Fernbedienung · Dlf Nova #fun, #hardware
Alle sitzen vor der Glotze, irgendwo vor einer Bar. Warten auf Tore bei der Fußball-Europameisterschaft. Und dann geht der Fernseher aus. Das ist fies. Und lustig. Vielleicht war unser Netzbastler Moritz Metz in der Nähe.

Sounds a bit complicated, but hey... It's Kubernetes after all.
Bye bye Travis CI | daniel.haxx.se #story, #cicd, #travis, #curl
In the afternoon of October 17, 2013 we merged the first config file ever that would use Travis CI for the curl project using the nifty integration at GitHub.
On to GitHub Actions, I like them.
