It's worth noting that most cloud container systems are also isolated VMs. This is partly for software compatibility (the guest can be a shiny new kernel, the host can be a LTS or CIP release), but mostly because cloud providers don't regard anything other than a VM as a defensible boundary.

Azure did a bunch of things with nested virtualisation, but they've now, I believe, upstreamed something to Linux that exposes a device compatible with KVM that lets one VM delegate pages to another and gives the abstraction of nested virtualisation where the 'child' is a child in the 'administration is delegated to the parent' sense and not in the 'recursive nested paging' sense.

people: ask their dependencies to follow semver, for fuck's sake already
also people: make a surprised pikachu face when the major version is incremented with every release

(i have been both, at times. this is about me. this is also about others who i've seen be a lot more militant about this issue)

the thing is, if you have a sufficiently complicated application it is not feasible to determine what is a "breaking change" or not. this complexity limit kicks in long before you get to a "browser" or a "JIT compiler" but it is definitely well applicable by that point

i think what people mean when they do both of those things are a mix of "please stop adding features entirely. only fix bugs" and "please only make changes i like, but not the changes i dislike" depending on maturity level. that's not really how open source software works though

I’m yellowcooln. I turn coffee into MeshCore projects.

I develop MeshCore tools like the live map now in use by various regional meshes, mesh health check dashboard, and other projects that help make mesh networks more usable.

I’m also involved with the Greater Boston Mesh community (https://bostonme.sh/) where we’re rapidly growing our Boston and greater New England MeshCore network.

@mboelen @msjl so one of our members from Boston - @aeblyve will be out in your area with their #MeshCore radio.

Make sure to look for them and say hi!

this ai bubble is going to burst any minute now, and we all know what that means: cheap data centre rack space in huge quantities.

can we use server racks to grow salad instead of swindle? i set out to find out: https://sa.lj.am/rack-mount-hydroponics/

The Ether Dome at Mass General Hospital also works as a conference room with a projector these days, creating this interesting composition.

We're moving house shortly and I'll be rebuilding my office. I have a terrible mix of computery things (NAS, switches, cables, etc.), books, electronics bits, and guitar building bits that don't live in a workshop. And then just projects in progress that dont' fit anywhere.

What sort of shelving/drawers/storage do people have that they're pleased with as a way of containing the mess?

There is an absolutely massive cliff between selfhosting and running services for other people, writing code for yourself versus for others. My advice to the new generation would be to try and get in the latter position as quickly as possible.
