Friends, is the fact that the Humble bundle that has my "The Book of PF" along with a number of other good titles, the "Dive into DevOps" bundle https://www.humblebundle.com/books/dive-into-dev-ops-no-starch-books has sold more than 8,000 bundles and made more than CAD27,000 for the charity a cause for celebration or should I hold off until we see rounder numbers? #devops #openbsd #freebsd #sysadmin #security #networking

Anyway the bundle runs until June 10th 2024, so get your clicks and cards ready!

I rather dislike the "digital native" term myself, but this article does make a number of valid points - https://www.theguardian.com/commentisfree/article/2024/may/24/banning-kids-from-social-media-isnt-the-way-its-the-over-60s-who-need-to-get-off-the-internet?CMP=share_btn_url

For those of you wondering what happened to the #PF #tutorial slides, the new home for the slides is at https://nxdomain.no/~peter/pf_fullday.pdf - as PDF for reasons only to be discussed over refreshments when we meet. New versions will be available at that location in sync with updated sessions. #openbsd #pf #packetfilter #freebsd #networking #ipv6

This is one of the best explanations of the xz matter I have seen so far:
https://lcamtuf.substack.com/p/technologist-vs-spy-the-xz-backdoor

and it leads in with a quote to remember -

"This dependency existed not because of a deliberate design decisionby the developers of OpenSSH, but because of a kludge added by some Linux distributions to integrate the tool with the operating system’s newfangled orchestration service, systemd."

Enjoy!

I am of course delighted to see people finding my #OpenBSD piece https://nxdomain.no/~peter/what_every_it_person_needs_to_know_about_openbsd.html, but I think the good people at #APNIC did an excellent job editing the thing into three more easily digestible chunks starting with https://blog.apnic.net/2021/10/28/openbsd-part-1-how-it-all-started/ #openbsd #needtoknow #security #internet
