But for real, what's going on over at Github?

When Claude writes test first: HAHA YES THIS IS GREAT
When Claude goes off the rails, spits out code, pretends tests don't exist: Listen here you little shits.

Sounds like open source with more steps.

Reminds me of the people promoting "everyone will have their own on-demand novels, movies, music and they will love it" and similar nonsense.

One of these days a bloom filter is going to be the solution to my problems. Today is not that day.

I have a new name for posts like this.

Where every sentence is spread out.

Lots of sentences. Many words.

And yet, says nothing unique or of importance.

And obviously written by an LLM.

Chicken nugget posts.

My 7 year old introduced me to the phrase "chicken nuggets for brains" and I've never had a phrase enter my daily usage so quickly.

Sounds like they're putting their thumb on the scale for Grok.

Figured this out just yesterday when Facetiming with someone and they said my audio was shit.

Highlighting the speaker who stood in front of the Surprise mayor and told him to consider what the Mayor of Ohrdruf must’ve thought before he died by suicide: β€œHe might have thought β€˜how is this my fault I had no jurisdiction over this’ maybe he said β€˜this site was not subject to local zoning.’”

It’s pronounced claw-day, right?

Ripping a Lilo & Stitch cd so I can put it on my iPod while waiting for Claude to finish a task is apparently something I do in 2026. What a weird timeline.

Labels not including track metadata on newly manufactured CDs has to be some of the laziest shit I've seen in awhile.

Not just business too. The amount of government related stuff that’s only available of FB is a weekly rant from me.

Buying physical media every time I read an article on AI written by three LLMs in a trench coat is a fun new way to play "markets can remain irrational longer than you can remain solvent".

Oh good question. I don't really know what I'm doing, but if you go with Proxmox and Tailscale, setting up subnet routes on the Proxmox host means you don't need to setup Tailscale on each container/vm.

I'm a few weeks into having a homelab and it's seriously so much fun. Over the weekend I needed a Windows install running on x86 (long story). I thought I was stuck since I have an M1 machine...until I realized I could just spin one up in Proxmox. 30 minutes later I was good to go.

Claude Code has greatly decreased the amount of time it takes me to go from idea to abandoned project.

I didn't even realize this was out already. πŸ‘€

Yeah, it was fun to see `duplicate` in the std library. I don't think I've had a use case for that before.

Enum.flat_map(1..n, fn i -> List.duplicate(i, i) end)

Your light mode might be too light.

A long known irony of automation is that as you automate the most frequent (and easy) cases first, people are left to handle both increasingly rare *and* challenging situations, with less practice.

If you didn't like content written for SEO, boy are you gonna hate content written for AI.

Hugs to whoever at Cloudflare is dealing with this outage. I do not envy you right now.

Hm, I probably need to go back and read the patterns book and tease out the pattern vs what’s in Rails.

Not at all.

Are any of you aware of an ActiveRecord Elixir implementation?

We're living through the Who Cares Era, where completely disposable things are shoddily produced for people to mostly ignore, while the government stomps its uncaring boot on our necks. But there's an easy way to fight back: Care.
