    The Techpriest Will See You Now

    Byirfmeister 2026-05-112026-09-10

    Working in security, sometimes I feel like the technical controls, policies and trainings only go so far. What we need to secure the company is a miracle. Some divine intervention to save us from damnation. So when I get a few hours over a weekend, I design and craft purity seals to keep the endpoints…

    Camino Didn’t Fix Me

    Byirfmeister 2026-04-192026-11-03

    My ex met her ex on the Camino… I always thought it was the most romantic thing ever. So, about a year and a half ago, I started planning to do the Camino. I figured out my leave from work, bought plane tickets, gathered the equipment I needed over time, and trained with weighted backpacks on long country roads… Yesterday, I returned home.

    Team Building Millennial Style: Stop Worrying and Embrace the Holy Hand Grenade

    Byirfmeister 2025-12-122026-11-03

    People of my generation and younger grew up with Worms. The lovable worms that give the game its name have a special place in people’s hearts. In every place I’ve worked, there were quite a few people who recognized the game immediately. So, in my opinion, it is the best team-building activity for any IT team.

    Reverse Management Tips from CIA

    Byirfmeister 2025-11-142026-09-11

    For your edification and pleasure, I present the CIA Sabotage Field Manual from 1944. Section 5, in particular, lists suggestions for civilians working under Nazi occupation on how to harm the war effort. Some of them are devious, out right devilish, like forgetting to provide paper in toilets. Others unfortunately remind me too much of how we work today.

    Co-dependency in Stereo

    Byirfmeister 2025-10-272026-11-03

    This will be a rambling, semi-incoherent post. It’s hard to put into words what I want to write, so I’ll get at it sideways: I’m turning my heartbreak into a playlist and talking about the songs (instead of talking about my feelings like a grown-up). The period from Fall 2024 to Fall 2025 has been…

    The Anarchist’s Guide to Corporate Change

    Byirfmeister 2025-09-292026-11-03

    Listening to the Ecology of Ideas Podcast with Alexis Shotwell, I got inspired to write this post. The episode is about getting around purity politics to affect political change, and it has some obvious anarchist inspirations. I found it ironic that I use pretty much the same principles to get things done in my corporate…

    No Multicolor, No Problem

    Byirfmeister 2025-07-202026-09-10

    The multicolor 3D printing is becoming more common. Bambulabs and their AMS, and Creality with CFS, we see a proliferation of multicolor printing. I do not have a multicolor printer. Over the years, I have dabbled with printing in multiple filament. I did this using a few hacks. Simplest one is to start the print…

    Midlife Crisis 3D Printer Saves Memories of Youthful Love

    Byirfmeister 2025-05-312026-09-10

    Most men buy a motorcycle or a convertible in their mid life crisis, maybe get a young girlfriend. I opted for a 3D printer. Then proceeded to ask: “What do I do with this thing?” I did have a few projects around the house, but eventually it became clear that the 3D printer was a…

    The Mind is Its Own Place

    Byirfmeister 2025-04-24

    I learned about Paradise Lost in my twenties when I came across this quote in a Whitewolf manual (I think… or maybe it was an issue of FRP & Magic?). Which way I fly is hell; myself am hell; And in the lowest deep a lower deep, Still threat’ning to devour me, opens wide, To…

    Daring Duo: In Pursuit of Altered Items

    Byirfmeister 2025-04-112026-09-12

    As the girls grew older they didn’t relate to the adventures of Monkey and Ferret sisters any more. So I wrote this one with the daring duo as the protagonists. The story was influenced a lot by what I was reading at the time. I am sure the bike that made horse sounds came from…

    John Stewart interviews Oren Cass: American Cluelessness.

    Byirfmeister 2025-04-07

    I’m a big fan of Jon Stewart, and I watched his recent interview with Oren Cass (see here). While it was interesting, I was surprised Jon couldn’t point to any clear examples of American “soft power.” Maybe it’s hard to recognize this from inside the US, given its advantages. It is easy for the rest…

    What I learned from being on a sinking ship?

    Byirfmeister 2025-04-02

    I had a varied career. I have been lucky that my interests led me to opportunities in cutting edge of technology and business. I worked as a researcher/professor in universities on three continents, worked as a data scientist supporting a major R&D department, finally I led the cybersecurity efforts in a scale-up in critical infrastructure….

    Could AI Act Be Used to Put an End to Social Media Madness?

    Byirfmeister 2025-02-07

    As I get older, I become more cranky. What used to excite me now frustrates me. Chief among these frustrations is social media. Once I poked my friends mercilessly on Facebook, now I can’t stand TikTok or Instagram. I no longer have any social media, and it makes life hard, as everything from poetry slams…

    Stories for Kids: Adventures of Monkey Girl and Ferret Girl

    Byirfmeister 2024-10-22

    I have two kids, and since they were born I have been telling them stories about Monkey Girl and Ferret Girl. Over the years, the stories evolved to include myself and our friends and neighbors. After my divorce from their mother, I started writing them in little notebooks. I plan to put some of them…

    NIS2 What it Means to Your Company

    No it is not a sequel to a horror movie. It is a directive from EU (Directive 2022/2555) that was supposed to increase the security standards for essential and important entities. You can find the full text here (Thank you EU!). The directive is quite tick and not every part of it applies to everyone….

    Social Media and Enshitification

    There was a lot of frustration after Elon Musk purchased Twitter. He quickly eroded moderation on the platform, and made some questionable decisions. This month there was an uproar over third party app support in Reddit. What is going on? Both CEO’s are basing their decisions on the need to turn a profit. The platform…

    Having Fun With Teaching

    Byirfmeister 2022-12-042026-09-10

    I taught my first class back in 2009. I have taught many classes since. I think something I quickly learned was everybody had a better experience when I was enjoying myself. So I did things that made the class more fun for me. Things like explaining cryptography through Shakespeare, use case diagrams via method of…
