<p>Look into openepaperlink. It’s an open source project that integrates with home assistant, and lets you control multiple tags over WiFi with just one device. you can create custom display setups in yaml to show anything you want.<p>my favorite that I have set up is a tag in my bathroom that shows me today’s weather and chance of rain when im brushing my teeth - I haven’t been caught by surprise in the rain since :)</p>

<p>if you read the thinking context while in plan mode (I had it shown to me, i think mistakenly, by switching modes while Claude was thinking a week or so ago) plan mode is just a pre-prompt saying “you are now in plan mode, don’t propose edits, read the code and understand how it works.”<p>it’s not an actual limitation on the harness.</p>

<p>really good piece, sums up almost exactly where I'm at with AI currently.<p>cognitive debt is a real problem in my domain (embedded software) because AI simply can’t debug the symptom when the reasons for the bug aren’t in code, and a stack trace may not exist. finding the REALLY hard bugs requires in depth systems understanding and the ability to connect things you’ve seen around the codebase together - and the fix usually isn’t adding code, which means the patchwork fixes Claude likes to do only makes things worse.<p>that said, it’s made writing harnesses and supporting tools WAY easier and faster, and my workflow is better for it. Searching the git history for the why of things is also made way easier; helping me to reason more effectively</p>

<p>Great idea, i love the simple html website :)<p>For determining the number of balls, i had an idea but not sure of how well it’d fit in. Could you feed the listing title, unit count, and description into an LLM with a basic “figure out how many balls are in this listing and make sure that number makes sense with the price” prefix prompt and then store that number with the ASIN? One LLM call per product should be pretty low cost, and it could automate a bunch of repetitive manual work</p>

<p>I’ve been wanting to get rid of Spotify for months as the service has been getting worse and worse and this might just be the straw that breaks the camels back.<p>Does anyone know of alternatives with 
1) decent discovery for new music 
2) preferably not self hosted 
3) a functional Linux desktop app
4) allows downloading playlists for offline listening<p>getting all of these in one place and having them work well is why I’ve been stuck with Spotify for so long :/</p>

<p>The USB-C step is humongous, and hard to implement.<p>the complexity is high, but how else can you tell a cable that supports USB4 (40GBps) from one that’s only good for charging your phone (and everything in between)? users aren’t going to be able to tell the difference (using a cable with no data lines is already a super common issue with people getting into MCUs) so the device needs to be able to tell how much data and power the connected cable can distribute automatically.<p>this also why usb-c extension cables (M-F) aren’t spec complaint<p>it’s a real cool port, but the complexity demon is definitely present in the spec :)</p>

<p>>  Hope the documentation is correct (it isn’t)<p>real<p>compared to every exception-based language I’ve used, rust error handling is a dream. my one complaint is async, but tbh I don’t think exceptions would fare much better since things like the actor model just don’t really support error propagation in any meaningful way</p>
