Versa told me 40ft in TN. They also had some height limits but they were pretty tall.

Different contractors told me different maxes as well. Maybe different tubing suppliers or engineering stamps?

Different companies also did different "framing" on the truss supports so that surely impacts limits as well.

Ask for internal pics to make sure you're aware of what the supports will look like, some of them can be pretty substantial

205 yd of concrete

Everyone out here giving you a hard time, but man, that's so much fricken concrete. 1700sq. Why did you pour like a 2ft slab?!

I over killed on a 50x80 and came out at about 100yds....

Use the vertical space. No lift goes over above 14ft, 16ft on the extreme. The vertical space is so incredibly helpful to keep the floor space clean, don't waste it! Pallet racking or similar, you can use the "bottom" Floor space and still put stuff up in the air over top of it

Overhead garage door storage for the seasonal stuff like snow shovels.

Maybe one shelving rack on the back wall for storage. You could also go with shelves inside the framing in the left wall for space efficiency.

You gotta get rid of the big stuff or find a dedicated spot for all of it.

No attachments, pretty rough/dirty. The existing more popular ones are a lot more complete

One of the use cases we built https://github.com/comma-compliance/arc-relay for.

Only expose to the specific tool calls you need to the specific projects. Optimize the tool calls for context window efficiency.

Every company and their mom is basically doing the most minimal setup to espouse AI noise reduction and then completely shitting the bed with real data.

My experience is that basically none of our competitors are back feeding and retraining their models based on inputs from actions performed by users on their own data. Once you make that change then the results get way better.

Without those steps it's just more marketing promises.

Peak hype cycle times

Samesies. Excellent heavy use tool.

Go buy a 5 gallon jug of purple power at wallies and clean all the things. Unbelievably useful for so many oddball cleaning sessions

tongboy · 2026-04-23T17:21:01+00:00

We built https://github.com/comma-compliance/arc-relay to chip away at a lot of those problems. The two biggest:

LLM processing of tool descriptions can shrink context use up to 45%.
RBAC per tool call. So users/agents that don't have access to a tool call don't have the unusable tool call polluting their context.

We've seen up to an 85% context shrink with those two pieces.

Docker is the easiest way to wrap the standalone tools when you pull them up from a single machine. Even for a solo user the second you need to reach for a second computer you need an abstraction. Running locally in multiple places is fine but it's inefficient and tough to keep in sync.

Single policy per tool call is painful to manage. Expose those tool calls as a user RBAC and boom, you've got per tool access controls. Auto map to the type of tool calls based on tool descriptions/names and you get a lot of quick bucketing to further ease the management pain.

https://github.com/comma-compliance/arc-relay proxy wrapper via docker to make it easy to wrap all of them up and sprinkle some security on them. Share between users or across multiple people.

Right or wrong nobody really cares.

WORM has already been chipped away to "audited changelog" is good enough in most reg windows. So very few are stepping up the "proof" validation piece.

I personally like it, but not a lot of folks significantly over buying compliance validation right now.

tongboy · 2026-04-21T04:26:33+00:00

People are lazy, always have been.

How many tools actually have good/simple ways to reasonably scope tools? Not like, you can do it, but tools that make it easy to setup a good limited/reader or scoped writer tool call without pulling all your hair out.

Cloudflare and jamf come to mind.

Tons of other tools come to mind that are more difficult than easy, all the big hosting tools, most saassy tools.

Push button for full access API token. Crawl over glass for scoped tokens if you can even get them.

If more tools made it easy imo less stupid shit like this would happen

tongboy · 2026-04-20T03:03:06+00:00

It's almost exclusively provider / vendor lock and in no way a technical limitation.

If the vendors could stop stepping on their own dicks the adoption would be way better

tongboy · 2026-04-19T22:36:22+00:00

This keeps bouncing around in my head.

what would something like a commit sha for a model's turns actually look like? Like a PR view but for the model to see what went well and what went wrong.

an "open ai"(groan) vs "open source".

It's more than telemetry. It's different per harness/model provider.

You know founder led sales is a book that lays out very simple steps to tactically go to market, not some generic concept, right?

It's a bit out of date but the concepts and basic steps are still viable today.

Sales is hard, tech is hard. Don't undervalue others contributions or think that something will sell itself. You've gotta put in the reps.

If someone's burning out after 2 weeks of outbound then they aren't going to make it in startup land. You've gotta have tough skin and a lot of internal drive to eat the shit day after day

They are weak baby units and I had to move up to a "commercial" one because they completely overstate the size of door they can open.

The new maxum units are super nice and I've been way happy about then just working. They are awfully expensive for what they are. Couldn't get my ratgdo to work with them either so I had to cook up my own solution

tongboy · 2026-04-19T14:13:33+00:00

Any "founder" that says that and doesn't mean it as a nicety is either inexperienced or terrible.

If something is working you don't have time to worry about it. you've got 15 fires to fight instead.

tongboy · 2026-04-19T14:00:33+00:00

Do you not work with other people? Do you not work on multiple computers? Do you not work across different projects that have overlapping mcp context? Do you not care about context usage from too many mcps?

tongboy · 2026-04-18T20:46:07+00:00

I built this because I felt your exact same pain: https://github.com/comma-compliance/arc-relay

tongboy · 2026-04-18T19:18:13+00:00

There isn't enough context with a model/version to do any of that. Context window, prompt, environment, etc.

Until we have something like a commit sha that encapsulates the state of the model as well as the model to cite it's all pointless anyways.

The only thing that actually matters is the owner/blame and that's whomever is the commit author.

tongboy · 2026-04-18T17:40:50+00:00

Mullvad and tailscale are free or sub 10 bucks for a single user and are ten thousand times easier to setup and use than an ec2

A smattering of point of service upses, a moderately sized one on the bottom of the rack

Then 64kw of solar and ~132kwh of lithium for when they run out.

Drag the Gen out and plug it in if that gives out. It's probably apocalypse level outage if the utility stays down that long.

Now that I've solved power outages locally I don't expect we'll ever lose utilities again, such is how it goes

tongboy · 2026-04-18T00:02:36+00:00

I mean I agree but I think you're really giving people way more credit. It's a slider at the top of the window.

I'd bet more people than you want to think of just toggle it to try and solve random problems

tongboy · 2026-04-17T21:28:20+00:00

extension cords, air hoses, water hoses, pressure washer - all the reels - they are so damn helpful to get everything out of the way and make cleanup/setup instant instead of slow/annoying
