I don’t use my TLR lenses as often, so storing is a concern. SLR lenses are more cylindrical, so they’re easier to store on end so they don’t roll around. TLR lenses are more brick shaped; also, the lens ID info is printed on the top of Mamiya TLR lenses. I’ll probably just fit them in the storage bag however they fit best.

Not immediately up-to-date at all times, but I use backports. Looks like they’re only a point release behind still. https://packages.debian.org/bookworm-backports/libreoffice

The only time it gets behind by a full version is if Debian Stable is really long in the tooth and Backports can’t compile something due to a compiler or library being really old or if Backports hasn’t been created yet because Stable is young.

Once I started using the tool lending libraries in the San Francisco East Bay, it was a game changer for simple maintenance.

Some bike shops also have public work benches with tools. https://www.boxdogbikes.com/about-1

I’ve been a user of Master PDF for years now. It’s my go-to for PDF markup in Linux. Their yearly renewal can be kinda wonky, but their customer service has been excellent.

I was going to say use the old timey fixed width typewriter fonts that the US Army Corps uses (PDF page 5 and beyond), but I guess that they’ve switched to Times New Roman.

Maybe use open source fonts like DejaVu and Liberation?
