I found out about the Nostr social network a couple months ago. The network is based on public key cryptography. While browsing the feeds, I noticed some people had really nice public keys which contained their username in some form, like Snowden’s npub1sn0wdenkukak0d9dfczzeacvhkrgz92ak56egt7vdgzn8pv2wfqqhrjdv9. My key is still being generated, since my username is quite a mouthful. So I wondered if GPG keys can be generated like this too. And of course, they can.

I hate how the lock screen works on Windows. This is perhaps an oversight and for me a security issue, so I’ll share some information on how to make it work better. This applies to pretty much all Windows versions in use today as far as I can tell. By default, when Windows turns off the screen, it won’t lock it. It makes no sense to me why this is the default behavior.

If you lock your 2008-2010-era Thinkpad with a supervisor password and forget it, there is not much you can do. Unplugging the battery won’t help (although I have heard that supervisor password on some models can be removed this way) and getting Lenovo to fix it for you can be time-consuming, especially compared to how easy to service and how well documented these machines are. This tutorial could work on other laptops, not only Thinkpads.
