I built my own weather prediction / visualization app: https://wx.rsp.li (on-device temperature lapsing, on device interpolation modes, user-selectable aggregations, etc…). One of these days I should do a writeup.
I enjoy Opus on personal projects. I don’t even bother to check the code.
Go/JavaScript/Typescript/CSS works very well for me.
Swift not so much. I haven’t tried C/C++ yet. Scala was Ok.
Professionally I hardly use the tools for coding, since I’m in an architecture role and mostly write design docs and do reviews. And I write the occasional prototype.
I have started building tools to integrate copilot (Opus) better with $CORP. This way I can ask it questions across confluence and github.
Leveraging Claude for a project feels very addictive to me. I have to make a conscious effort to stop and I end up working on multiple projects at the same time.
yes. depending on the techstack your experience might be better or worse.
HTML/CSS/React/Go worked great, but it struggled with Swift (which I had no experience in).
you have to ask it to profile and optimize the code for you. Then have it document the changes and run it in a loop. It’ll do wonders.
I asked a cursor agent to do the same for a geotiff to pmtiles converter. It managed to optimize the performance from tens of days to half a day for the case I wanted to solve.
I also use Fastmail to host my calendar and contacts - next to my email. I enjoy the web interface and lI especially like that the iOS integration just works.
I also asked Claude to build a photo gallery for me https://places.pascalspoerri.ch (HDR, map support, similar images)
