What Hacker News says?
Asking the real questions here. I finally gave up on using an XPS15 with Ubuntu because I could not get over the fact it cannot do high quality bi-direction bluetooth audio. Edit: Looks like it does offer some improvments over pulseaudio: https://www.redpill-linpro.com/techblog/2021/05/31/better-bl... .

HN discussionI urge everyone to actually read the blog post by Geoff Huston. From what I can tell, it does not say what tptacek says it does.

HN discussionIs lower-level fingerprinting enough to detect the difference between ARM / x86 linux? How far would I have to go to setup a truly legit honeypot on a Raspberry Pi? Is anyone already doing this? The following article doesn't get into userland IP stack: https://www.redpill-linpro.com/sysadvent/2016/12/19/raspberr...

HN discussion> Almost every time anyone mentions DNSSEC here on HN, you pop up like a jack-in-the-box to claim that nobody is using it and that it is dead. And it’s always you, nobody else. Yup. > You might have some valid criticism about the cryptography; I would not be able to judge that (except when you are basing it on wildly outdated information). Yes—context matters. Unless someone knows the details of how DNSSEC works, th…

HN discussionLove y'all and love matrix. Thanks for the free matrix.org server. But maybe now is the time to research setting up a home server for mission critical stuff? I don't immediately see an official doc on this; is it right under my nose? Is this doc good? https://www.redpill-linpro.com/techblog/2025/04/08/matrix-ba...
