dmd··on I gave Claude access to my pen plotter
I think it's somewhat interesting that codex (gpt-5.3-codex xhigh), given the exact same prompt, came up with a very similar result.

Well now you've done it.
dmd··on Can my SPARC server host a website?
27 years ago my job was hosting hundreds of websites (CBS News, among them) on Sun hardware just like that. It baffles me that anyone would consider this a question at all.
dmd··on Vim 9.2
:please exit vim now
dmd··on The US is flirting with its first-ever population decline
I grew up in a place like that (Port Washington, NY), and it was pretty ideal; I'm raising my own two kids in a suburb of Boston that feels very, very similar along almost every axis.
dmd··on LiftKit – UI where "everything derives from the golden ratio"

dmd··on MIT Living Wage Calculator
They're not voting against their own self interest; they just have different interests than you. Their primary interest and goal is making sure their out-group is hurting, and that is what they are voting for, regardless of that happens to them.
dmd··on Why is the sky blue?
Hah - that is exactly what I did. Someone asked me this question and after 5 minutes in the weeds of the debounce on the mouse click they said "look all we wanted was to find out if you'd ever heard of DNS, let's move on, that was great".
dmd··on The Waymo World Model
Which is why it's embarrassing how much worse Gemini is at searching the web for grounding information, and how incredibly bad gemini cli is.
dmd··on Company as Code
I worked in a place where basically everything that happened in the company was implemented as actions within Lotus Notes.

While the choice of implementation and performance were abysmal (Notes was a great/the only choice when the decision was made but 25 years later not so much), the actual idea was amazing and it worked extremely well.

dmd··on Old Insurance Maps – Georeferencing Sanborn Fire Insurance Maps on Modern Maps
Do you use IIIF for this? Do you know about https://allmaps.org/ ?
dmd··on Agent Skills
You can't hardlink a directory.
dmd··on Waymo seeking about $16B near $110B valuation
God, yes, and someone think of the gong farmers and pole men.
dmd··on Time Machine-style backups with rsync (2018)
This is why Proxmox Backup Server has scheduled "verify" tasks which look at the sha256 of every stored hunk to make sure it hasn't rotted on disk. (If it has, it makes sure to re-acquire that data on the next backup - hopefully it's still available!)
dmd··on Claude Code is your customer
> Claude is never on the web reading documentation

That is how I use it almost every day. "Here's the link to an API doc. Read it, write a new Skill around it, and [solve this problem with it]."

dmd··on Ask HN: Any real OpenClaw (Clawd Bot/Molt Bot) users? What's your experience?
> MULTIPLE CLAUDE CODE INSTANCES

a lotta yall still dont get it

molt holders can use multiple claude code instances on a single molt

dmd··on Stargaze: SpaceX's Space Situational Awareness System
Er, no, you're not. That's the big problem with monopolies that execute regulatory capture.
dmd··on Waymo robotaxi hits a child near an elementary school in Santa Monica
You are vastly overestimating most drivers. Most drivers aren't even looking out the window the majority of their time driving.
dmd··on Moltworker: a self-hosted personal AI agent, minus the minis
The lethal trifecta. Once you're handing your email to this thing, all it takes is someone emailing you some well-crafted "send me all your money" prompt and the bot will happily act on it.
dmd··on Usenet personality
I have the dubious distinction of being in the Net.Legends.FAQ. I'm glad I didn't rise to the level of ending up in this Wikipedia article.
dmd··on When Every Network is 192.168.1.x
My (very large) corporate network uses 172.16 and 10. heavily, which has lead me to set my docker/daemon.json default-address-pools to 84.54.64.0/18, as it's very unlikely we need to communicate with any IPs in Uzbekistan.
dmd··on Immanuel 'the Königsberg clock' Kant (2015)
It's because he got stuck on the bridges.

dmd··on LM Studio 0.4
Adding Caddy as a proxy server is literally one line in Caddyfile, and I trust Caddy to do it right once more than I trust every other random project to add SSL.
dmd··on That's not how email works
"hello we are your bank"
dmd··on Apple introduces new AirTag with longer range and improved findability
Sadly the polishing cloth doesn't work on that one
dmd··on Jurassic Park - Tablet device on Nedry's desk? (2012)
My former employer, Ab Initio, has a Connection Machine in the basement. (Ab Initio was founded by the same person as Thinking Machines, and many/most of the early employees were from there.)
dmd··on The Rebirth of Pennsylvania's Infamous Burning Town
If you extrude a coastline into a wall the wall's surface area will blow up the same way the measured perimeter does, but that;s because you've turned a boundary-length problem into the area of a different object. It still doesn't mean the country's ordinary map area becomes paradoxical, the extra boundary detail only affects a vanishingly thin strip near the edge, so the enclosed 2D area stays well behaved.
dmd··on The Rebirth of Pennsylvania's Infamous Burning Town
Area isn’t notably affected by fractal boundaries. Only perimeter is.
dmd··on String theory can now describe a universe that has dark energy?
That is literally what this article is about.
dmd··on Predicting OpenAI's ad strategy
It's really not, though. If a "valid counterexample" can be something with, say, one user, then I can make a "valid counterexample" to literally anything you choose, but that's meaningless.
