Three episodes, one week. AI bots that hallucinate VPN requirements, recommend Apache configs on nginx servers, and suggest replacing 128 GB of RAM with a cloud VPS. A field note on the cost of mistaking confidence for competence.

IT Notes

Meet Fedibook!

The idea came from thinking about what it actually takes to get regular users onto the fediverse. Mastodon is great (i love it), but the follow-based model feels unfamiliar to some. Friends and Groups though β€” that's something everyone already understands.

So Fedibook is a fediverse platform built around exactly that, using ActivityPub. Think federated address book meets social network, with the kind of social graph people are already used to.

Current status:

- Friend requests across servers working
- News feed working, with visibility levels: public, friends-only, or local server only

Hoping to open up for early testing and feedback soon. Open source of course.

The goal is to make corporate data less profitable.

Even stuff as simple as setting your birthdate to 1970-01-01 everywhere, adding [TEST] or [DELETED] as your name or account notes anywhere you don't need them to know your name.

Using plugins like AdNauseam to poison ad trackers (and cost them marketing dollars).

Using VPNs set to different locations.

Signing into data broker sites to "correct" outdated info (they'll often let you do that with little-to-no proof of identity, but will require your passport or state ID in order to delete your info). Bonus points if you correct it to someone else's info on their site that's similar to yours.

Only fill in required fields when you sign up for anything, but only provide correct info if it matters for you to use the service, otherwise provide plausible, but incorrect, data.

If you use LLMs anywhere, use the free tier and always vote thumbs up for bad answers and down for good ones. It wastes their resources and drives up their costs while making their training data worse.

πŸ†• blog! β€œI'm OK being left behind, thanks!”

Many years ago, someone tried to get me into cryptocurrencies. "They're the future of money!" they said. I replied saying that I'd rather wait until they were more useful, less volatile, easier to use, and utterly reliable.

"You don't want to get left behind, do you?" They countered.

That struck me as a bizarre sentiment.…

I'm OK being left behind, thanks!

Many years ago, someone tried to get me into cryptocurrencies. "They're the future of money!" they said. I replied saying that I'd rather wait until they were more useful, less volatile, easier to use, and utterly reliable. "You don't want to get left behind, do you?" They countered. That struck me as a bizarre sentiment. What is there to be left behind from? If BitCoin (or whatever) is going…

So:

1. AI can not generate original content
2. AI is writing new code for programmers
3. Therefore, AI is re-purposing old code _from_ other programmers
4. Conclusion: this new code shouldn't need to be written, since it's been written before

Network Management with the OpenBSD Packet Filter Toolset AsiaBSDCon 2026

The OpenBSD Packet Filter (PF) is at the core of the network management toolset available to professionals working with the BSD family of operating systems. Understanding the networking toolset is essential to building and maintaining a functional envirionment. The present session will both teach principles and provide opportunity for hands-on operation of the extensive network tools available on OpenBSD and sister operating systems in a lab environment. Basic to intermediate understanding of TCP/IP networking is expected and required for this session. Topics covered include * The basics of and network design and taking it a bit further * Building rulesets * Keeping your configurations readable and maintainable * Seeing what your traffic is really about with your friend tcpdump(8) * Filtering, diversion, redirection, Network Address Translation * Handling services that require proxying (ftp-proxy and others) * Address tables and daemons that interact with your setup through them * The whys and hows of network segmentation, DMZs and other separation techniques * Tackling noisy attacks and other pattern recognition and learning tricks * Annoying spammers with spamd * Basics of and not-so basic traffic shaping * Monitoring your traffic * Resilience, High Availability with CARP and pfsync * Troubleshooting: Discovering and correcting errors and faults * Your network and its interactions with the Internet at large * Common mistakes in internetworking and peering * Keeping the old IPv4 world in touch with the new of IPv6 The tutorial is lab centered and fast paced. Time allowing and to the extent necessary, we will cover recent developments in the networking tools and variations between the implementations in the sister BSD operating systems. Participants should bring a laptop for the hands on labs part and for note taking. The format of the session will be compact lectures interspersed with hands-on lab excercises based directly on the theory covered in the lecture parts. This session is an evolutionary successor to previous sessions. Slides for the most recent version of the PF tutorial session are up at https://nxdomain.no/~peter/pf_fullday.pdf, to be updated with the present version when the session opens.

Adding Solaris and SunOS to my LinkedIn profile :D

(this was to once have seen a Solaris shell and add it... HP-UX, Tru64, AIX, FreeBSD, ...)
