in addition to all the obvious gender-conspiracy-theory gobbledygook, can you imagine being do desperate for recognition that you list "8 NYT Bestsellers" *and* both "Dr." & "DPhil" in your username 🤣

Come for me, you best not miss
Fascinating! can you talk a bit about the UX trade-offs of automatically rebasing descendants of amended commits and the various choices made by historical and current version control systems?

every opportunity to relieve drudgery has its own moral weight. Deciding one doesn’t care about this is a personal calculation
but demanding that math be universal just doesn’t seem like an adult perspective to me

I've been sitting with the discomfort here a bunch, and to me this is it, right? What is being suggested is that I engage in an act of self-flagellation (resolving thousands of lines of merge conflicts by hand) because the richest man in the world uses some of the same underlying tech to peddle CSAM
![Screenshot of Claude Code terminal interface showing a migration progress checklist
The terminal displays a dark-themed interface with two tabs labeled "1: fg" and "2: ~" at the top. The main content shows a detailed task list for what appears to be a Rust codebase migration project.
The upper portion (lines 47-54) shows completed tasks highlighted in green, including items like "PrivateIpStackCreate enum," "InstanceNetworkInterfaceCreate with ip_config," and creating dual_stack_nics files for floating_ip.rs and probe.rs.
Below that, lines 43-54 show another set of completed tasks (marked with [x]) in a green-highlighted block, detailing work on dual_stack_nics/instance.rs including IpAssignment<T> enum, type aliases, and various struct implementations.
The middle section shows "Phase 4: Add Types to silo_project_ip_version_and_pool_type" with a file being written containing Mozilla Public License headers and module documentation about adding ip_version and pool_type fields to SiloIpPool responses.
At the bottom, a "Cerebrating..." status bar shows the AI is thinking (1m 30s elapsed, 5.7k tokens). Below this is a checklist of remaining tasks including completing dual_stack_nics/instance.rs, creating version module files, updating latest.rs, resolving conflicts, and running cargo checks.
The footer shows "accept edits on (shift+tab to cycle)" indicating pending code changes awaiting user approval.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:sl3g3nhnad34sfhjnqdivbzd/bafkreiep35hi26nxyemiy4v2tvo7mlkftnbwice3rvs3phucmlnbzguw3q@jpeg)

The thing that's been shocking and disturbing to me is how far you can get with what is essentially pure syntactic manipulation. Never would have imagined this
the best/worst one was where i had three features that relied on each other, and i had implemented 1 and 2, but not 3. Claude said "hey so, the way you built 2 may make building 3 hard, we may want to revise 2 before we go on to 3" and it was 100% right, I hadn't considered a requirement

Claude Code really likes resolving 10k line merge conflicts if you give it a spec to work with, and both sides of the conflict in separate jj workspaces

One clear benefit of being open to LLM use is to repel people who do this kind of thing. I'm really fucking pissed.

I still believe you shouldn't attack the creator of the list personally. But I no longer believe it is in good faith, given the large gap between stated goals and revealed behavior

"It's just ADHD" you say. Well, yes, it is. But mf do you know how bad my comedown from even 2.5mg Ritalin tends to be
I'd had a design sitting in my head for *years*. Never could motivate myself to do it just because of how tedious it is. With Opus 4.5 I got it done in *one day*

While quite sick yesterday I got a prototype of a long-awaited nextest feature, being able to replay old runs. Was the code terrible? Yes, it's going to require many hours of work to bring up to standard. Did the feature work? Yes, absolutely, and I can now start dogfooding it which is wonderful

Oh one place where there is (a) a ridiculous amount of boilerplate (b) that is 100% justified is when you have serialized and internal data models. much of the time, you don't want to tie one to the other, so you create tons of duplicate structures

I'd say it like this: Claude Code doesn't do defensive programming in Rust.
Defensive programming is *really* valuable for long-term maintenance, and if the coding agent isn't doing it, you need to ask until it does, or do it yourself.

Just now it did a thing where it made two separate maps (one for valid items, one for invalid items) instead of using the same map to track. CC's approach makes a lot more invalid states representable than the more refined approach
for many problems it'll write working Rust code just fine, but there's a difference between that and the kind of code an experienced practitioner would write

have seen some folks mention or contemplate that there were parts of “Woke 1.0” that were inept, too much, ham-fisted, etc. Without putting anyone on the spot, has anyone more concretely described what, exactly, they think were the inept or too much parts?
