In the TanStack CLI? It used to be able to do that. I'm not sure about the current release though. We simplified that A LOT.

My wife almost died a couple years back. So we kinda look at every day like "Oh, fun, we get an extra day, what can we do with it?"

Jack Herrington @jherr.dev · 20/04/2026
I'm Gen X. Latchkey (literally) all the way. I'm like a honey badger. I can do anything myself. All day chef. So if an LLM can do a decent job, cool, I'll use it. If it can't do it, I'll find another way. Or I won't do it at all.
110
Jack Herrington @jherr.dev · 20/04/2026
This probably sounds flippant but if I need determinism then I'll use a deterministic tool. If I'm using an LLM it's because I'm ok with it working. But I'm not lost if it doesn't work.

@tanstack.com Start is remarkably flexible when it comes to SSR and now RSCs. It has five different ways to render content from the server and you can mix and match. Do you know them all? youtu.be/PX3QlADinIE

i will say that my personal experience with it is strongly biased by the fact that i'm dyslexic. and it seems to work with my wonky brain. explaining things in a way that i seem to grok better than I have with other educational styles.
110
Jack Herrington @jherr.dev · 16/04/2026
so yes, i'm optimistic about it, and i enjoy it, but it's also frustrating when it screws up, and it does screw up. it'll get stuck in a rabbit hole. or it'll remember random stuff that's no longer relevant. and at those times I just ignore it.
100
Jack Herrington @jherr.dev · 16/04/2026
and that's a lot of what i do, i don't let it drive (most of the time) but i do use it for ideas, alternatives, and yes, learning new stuff. so yeah, my relationship with it is different than with a search engine.
100
Jack Herrington @jherr.dev · 16/04/2026
for example, a couple of days my beloved cordless drill of 30 years finally gave up the ghost. so I had a really long conversation with Claude about what to replace it with. and it was a collaboration, it would offer some comparisons and then i'd go and have a look.
100
Jack Herrington @jherr.dev · 16/04/2026
really interesting points. and the prison complex story is wild. i've experienced bad google maps, but it never routed me through a prison complex. for me the difference between straight Google search and Claude (just as an example) is the ability to ask follow ups.
100
Jack Herrington @jherr.dev · 15/04/2026
This is a fascinating conversation to have. It's super relevant. But I gotta tell yah, I'm taking on a lot more ambitious projects with a wider array of techniques and materials than I ever have before because I know I can just fire up Claude and say; why isn't this working?
110
Jack Herrington @jherr.dev · 15/04/2026
Another example is sometimes videos leave stuff out, or assume a level of skill I haven't achieved. For example, I didn't know the chisel tip was the best thing to start with. I always went with the pointy one because, y'know, point... But turns out, chisel is much easier.

Jack Herrington @jherr.dev · 15/04/2026
Where with AI it can say; "it should look like this", and when it doesn't I can say, "No, it's not glossy it's gray...". And it can say in the moment; "Oh, your iron is too cold." Blah blah blah.
100
Jack Herrington @jherr.dev · 15/04/2026
Soldering is a great example of this. I've watched videos on it in the past, but at the moment where my soldering doesn't look like what's happening in the video then the video becomes worth less. (Not worthless, just worth less.)
100
Jack Herrington @jherr.dev · 15/04/2026
I see where you are going, and I agree, I think it would be ideal if I wasn't using AI. That being said, I think the reason that it works for me is the same reason it works for a lot of folks; an unlimited ability to ask hyper-specific contextual questions in the moment.
110
Jack Herrington @jherr.dev · 05/12/2025
Dude, it's an alpha. We're looking for feedback. We hear yah. I think that got lost in the shuffle when I added some more type validation around tooling. Definitely need to bring that back. Just chill out though, nothing is set in stone. It's a 0.0.1 release. :)
