GPT-5 mini loves try-catch statements. It frequently generates code with nested try-catch about three levels deep.

You can get a sense for how challenging CSS can be when you try multiple LLMs and none figure out how to get an image to be vertically aligned to the text next to it.

We just led a round into Magnetic Tax two weeks before the Summer YC Demo Day. Magnetic Tax is computer-use agents for CPA firms to automate taxes. The unlock here is CPAs don’t need to rip out their clunky, but trusted, legacy tax software to use Magnetic.

An interesting quirk of GPT-5 in writing my tech specs: it likes to give options by default. So it'll write something like "Either do X or Y" instead of being specific about what to do. I've had to adjust my prompt accordingly.

Francesco knocked this one out of the park.
ESLint v9.34.0 features parallel linting! Most projects see around a 30% reduction in linting time. The more files in your project, the greater the improvement. Read about how this ten year old feature request finally came to be:.

Here's a problem AI couldn't figure out: how to run multiple Cloudflare workers locally at the same time so they can use the same resources (queues, etc.). Took me a bit, but finally figured it out.

Wrangler is made primarily to run one worker at a time. You can also use it to run all of your workers at the same time.

Just migrated the metadata fetch queuing logic of Bredbox (my Pocket clone) from Supabase Edge Functions to Cloudflare Edge Workers. Really smooth transition. Love the Cloudflare local development experience.

A couple of really good time loop-related TV series:. * The Lazarus Project (Netflix).* Devil's Hour (Prime Video). Really enjoyed both. I'm a sucker for a good time travel story.

Ping @pierceboggan @digitarald 😬.
The microsite is live!. Think of it as a README for agents: a simple, open format for guiding coding agents. It’s been awesome to work alongside peers from @AmpCode, @cursor_ai, @julesagent, @FactoryAI, and @roo_code to bring this to life!.

Thinking about what to do when someone adds a URL to Bredbox (my Pocket clone) that they've already added. Would you expect:. a) An error that prevents you from re-adding.b) Silently allow duplicates.c) Move existing bookmark to the top for easy retrieval.d) Other.

Not sure what's going on with Copilot today, but it's random changing indents on different lines. Sometimes too much indent, some times too little.

I built the Bredbox prototype on Supabase exclusively, but found the storage, queues, and edge functions not quite to up to the task. Switching to Cloudflare.

Tried out Jules and all was going well until I realized there are no scrollbars on any of the panes. Tried in both Chrome and Firefox. Seems like a bug?.

Years in the making. Worth the wait. 👍.
Coming next week: parallel linting that speeds up your CLI run by around 30% (some report even better results).

Just hit a milestone in Bredbox (my Pocket clone): Successfully imported my exported Pocket links CSV. I did not write a single line of code for this import feature. It was all AI. (head exploding emoji). Join the waiting list now:.

Observed some quirks about GPT-5 mini:. 1. It has a tendency to freelance, kind of like Claude. It guesses at additional things to do and sometimes is wrong. 2. It likes to randomly delete lines in unrelated parts of the code. 3. It LOVES running tsc even when it's not necessary.
