When my wife was diagnosed with cancer and eventually went into remission, I didn’t really process what was happening at first. I was completely focused on getting her through it. The grief hit me later.

What helped me more than anything was going out into the garden and digging. I made sure to do it safely, since I know it can be risky, so I dug wide and with wooden supports, but there was something about just digging and digging down that let me work through all the darkness that had built up in my head. It gave those feelings somewhere to go.

This is unrelated, but I wonder if I did actually hit on something primal in myself.

You found your chew toy.

Joking aside, I too have spent many days digging with a shovel and pickaxe on my desert property. There's something to it, even Jim Keller (of DEC, AMD, Tenstorrent...) has discussed digging trenches in some of his podcast interviews.

Winston Churchill famously used to build brick walls to deal with the "black dog" of depression.

Best digging I ever did was in a torrential downpour for 4 hours. Mud and grass was flying everywhere, my shoes were squeaking as they drove down the shovel. I was soaked to the bone and my heavy, cotton clothes slapped freely against my skin with each shovel full I tossed to the side. That was some of my favorite digging ever.

Colin Furze ftw!
https://en.wikipedia.org/wiki/Seymour_Cray

> Cray avoided publicity. There are a number of unusual tales about his life away from work, termed "Rollwagenisms", from then-CEO of Cray Research, John A. Rollwagen. Cray enjoyed skiing, windsurfing, tennis, and other sports. Another favorite pastime was digging a tunnel under his home; he attributed the secret of his success to "visits by elves" while he worked in the tunnel: "While I'm digging in the tunnel, the elves will often come to me with solutions to my problem."

Yeah, but he didn't make crazy yt videos!
Brings to mind this woman's efforts -- very impressive indeed:

Edit: reading is hard -- I only skimmed and did not realize she was mentioned.

He explicitly mentions her in the video.
We love engineer Kala. She decided to do a thing, while marking progress on her "technology tree" of skills gained by (very arguable) necessity. Dealing with permits and city beuaracracy seems like one of the hardest parts!
This article/video really rubs me the wrong way. These strawmen who are being torn down for the most part aren't building "tunnels". They're building glorified 8-10ft foundations and basements with dirt over the top instead of structures, 1970s hippie "underground homes" basically. They're calling them tunnels and bunkers for clicks and views.

To then take that naming at face value and pontificate about code and engineering is very much a two slights of hand not making a right situation. Furthermore, a civil engineer doing so is deep into "man won't understand what his salary depends on him not understanding" territory.

I know that the many HNers from the seismically active portions of the US will have no frame of reference for this but there are portions of the world where for hundreds, sometimes thousands, of years basements were built with less than scant engineering. The sort of "just barely below dirt" construction most of these amateurs are engaging in is on that order of complexity. Based on my observations via Youtube, these amateurs should be more scared of their own temporary construction rigging and material handling solutions than the forces their structures must hold back.

The primary practical engineering challenge and hazard these structures face is that there's nothing stopping someone from driving a point load of undefined size over the top and that has serious implications for roof strength.

As they say, the rules are written in blood. I don't think we should be disqualifying projects because they are not Mponeng-scale or complexity.

I am not a civil engineer, but I did spend a bunch of time looking into building an underground range. Way more relaxed life safety reqs, smaller bore, etc. However, when you start reading, it is clear that much of the work is empirical, heavily localized and based on a great deal on the experience of the builder. I found very little in the way of solid theoretical modeling, but lots of measure, adjust, etc.

I think Grady does a reasonable job highlighting the dangers and risks.

Seymour Cray down in the tunnels, communing with the Machine Elves.
Great content for the upcoming drone wars and the inevitable tunnels that will be built for troop and matériel movements
Obligatory shoutout to Engineer Kala
i thought for a second this referred to building a tunnel for openclaw haha. I need to get off Twitter
At this point we have too much free time on our hands x_x
I can’t wait till world models are good enough that you can ask robots to work autonomously to geo transform spaces.
Was hoping this was about network tunnels…

There's a lady on Instagram that goes by the handle 'engineerkala', who's been building a tunnel/mine below her home and learning the process along the way. I'm pretty sure one day the account will go dark when she's entombed herself a hundred metres below her living room, but until that comes it's a fascinating and extremely entertaining page to watch.
I don’t know how Colin Furze hasn’t come up in this thread yet. He has built a sprawling series of tunnels and rooms under his home and not in some cursory, lip service way like Kala.
I'm probably not the only person who thought this was about ssh and possibly handrolling something

that said, I've been latently fascinated by this kind of project. I've seen a couple of how-things-work/maker/dare-me-to-do-it type shows from UK and US where folks single handedly do stuff like this, though they're all hairy dudes unlike Kala, whose channel looks pretty cool

This is a very cool frontier for a homeowner, to not just have dominion over your terranean space by growing edible veg and habitat for animals but also use your below ground asset for who knows -- domicile extension or DIY geothermal or ...?

Gemini tells me in the US, land ownership theoretically extends to the Earth's core

I don’t like these posts because they’re just transcripts of a video. It’s a form of slop which predates AI.
There's a lot of value in transcripts of videos being provided next to the original content. It improves accessibility for a lot of people and helps out those of us who might be searching content or not in a place where they can watch a video but can read. Why would it be considered slop?
My wife and I have an excavator on our property that we use for making trails, trenching, digging up stumps, etc. All of it is exhilarating. But, nothing beats simply digging. Something about breaking through the top layer and getting a big scoop of earth that just feels real good.
house gotta have sipapu
How far down does a person own, on their property? I mean, keeping things (relatively) simple-- and residential-- and assuming you respect the water table, utilities, etc?
