I know right?

This one was straight up posing for the camera while it sat on my finger.

That seems excessive for that far north right?

Here is northwest Arkansas today

Not exactly walkable like most of our country.

I've built a few, but at this point, I just want a house to live in and don't really care who builds it.

I am especially proud of this deck I built for my parents.

I don't think my solar is performing well today.

I don't know why, but this function implementation really makes me happy.

It took me way too long to get it right, but it's just perfect now :D
export function eytzinger<T>(arr: T[]): T[] { const n = arr.length const tree = new Array(n) let i = 0 function build(k: number): void { if (k > n) return build(2 * k) tree[k - 1] = arr[i++] build(2 * k + 1) } build(1) return tree }

Things I find while living with seven children, edition 2376:

There is a small white pony bead with some tiny green plant potted in it. (Pencil for scale)

Some light reading.
Several books on a homemade desk about programming, soft skills, management, the meaning of life, and classic science fiction. Also seen are a lock, a caribeaner and large magnetic spheres in a circle.

Blue metal roof finally installed!

Next step is white vinyl siding...

I'm allergic to cats, and yet we rescued this stray a while ago.

He is the most snuggly and grateful kitty I've ever seen.

I was working outside building a shed, and he walked up to me asking for snuggles.

You can hear the purring across the room when I hold him like this.

I'm designing a 3d printed enclosure for a small P2P home server appliance thingy. I'm hoping to be able to put some neopixels inside so they can shine through the etching.

What do you think?

This interactive append is amazing!

It's not the part I'm trying to understand, I understood the sideways tree years ago. But this is a fabulous way to explain it!

Does anyone here understand what the indices in the 3rd column here mean?

This is from the old DAT design for path based trees.

The walls of the storage shed are framed out.

I ate dinner on site using a spool as a table.
2x6 frame of rectangular shed with angled roof and doorway A large wire spool turned on its side in the dirt in the woods with some guage large wire still on it. On top is a flowery dinner plate with pizza, a large water bottle, an impact driver and a portable radio.

Still digging, but getting close to done. Are the new wires big enough?

I've been digging today.
Large dirt trench with pipes laying around and a scaffolding bridge Tim digging in a huge hole with a hand shovel. Main utility power lines getting spliced back together because they were cut in half by the digging. Two hens searching the bottom of a long fresh trench for food.

One of the plastic bits in my car's charger port fell off while on a road trip to Austin (500 miles away). Luckily the piece was jammed inside and I was able to pull it out and reattach it!

I was so close to buying a 3d printer, reverse engineering the other piece and cloning it.

I replaced my scary transfer box bypass in the 5th wheel with a proper breaker box so I could tap into the main power to power 3 mini splits and a clothes dryer.
Blue marine switch with bare messy 6 awg wires Tidy breaker box with the same 6 awg wires as input and a single 240v 50a output. Also has 3x 240v 20a breakers, a single 240v 30a breaker and two small 120v 20a breakers.

Rate my setup.
Curved dell ultra monitor on homemade wooden stand with ROG Ally docked underneath. There are two large bookshelf speakers, a glowing gaming keyboard and a massive glowing midi controller keyboard. All on a plastic fold out table inside a dark grey steel trailer with metal storage shelves nearby and a magic leap AR headset on the table.

The blue sky turned red. This is amazing for Arkansas!

I recently broke down and paid for a Garmin watch. It's one of the only ones that actually report Sp02 numbers. And so far it's accuracy is actually pretty close to a finger tip pulse ox when I've spot checked it.

I cooked black beans and rice.for supper today. I set up a table outside to cook since it was nice weather. Did you know that in sunlight, they are actually quite purple? 🟣
