π‘TIL: 3d printed parts have different strength characteristics than conventionally-manufactured parts
An interesting 3d printing lesson about how the physical characteristics of printed parts differ from other manufacturing:
I needed to replace a rubber hydraulic hose retention strap on my tractor. The part’s $40 + shipping – ludicrous for a 6x2" strip of rubber – so perfect to try to replicate. I have some TPU filament that’s of similar flexibility, let’s go.
For V1, I just replicated the geometry exactly - including, without thinking about it, some little relief holes around the main hose holes:

π Changing Directions
I have two important announcements:
I’m leaving the tech industry. Hopefully “for good”; if not, at least “for now”.
As such, the content on this blog is going to shift, perhaps dramatically. I’m going to be writing about a broader range of topics that interest me (projects around my hobby farm, wilderness trips, emergency medicine) – more writing for me, less writing for some imagined audience. (I’ll probably still end up writing about some of the same topics as I’ve been covering since 2020, just less often.)
I’m writing this post mostly to give myself permission to make that change, and to give readers the opportunity to unsubscribe/unfollow if they’re not interested.
If you’re interested in more details about why I’m leaving the industry and what’s next for me and this blog, read on.

π Building a Community Privacy Plan (#)

π The 2025 journalistβs digital security checklist (#)
A pretty good checklist. Some things are tailored for the relatively-higher risk faced by journalists, but with some judicious βnot applicableβ application could be a good checklist for anyone.

βGhost is a distributed non-profit foundation which gives away all of its intellectual property under a permissive MIT license. The company has no investors and, in fact, no owners of any kind. I don’t own any part of Ghost, and neither does my co-founder Hannah.

“Wait, what?”
I’m glad you asked.β
