Damn, I already loved "Rocky Road to Dublin" so I don't have where to go from there. Guess it just went to 11 🙌

weekend experiment: a simple instrument that, technically, uses only one string.
it's always in tune with itself, and there's only a single tuning peg.
it should sound better once I find a proper string that long - had to use a fishing line for now

Omg I just found a score I wrote 23 years ago that I was absolutely sure did not exist anymore.

Iconify is one of the greatest resources I know for icons in your app or website.
1️⃣ Go to iconify.design
2️⃣ Find the perfect icon and copy it's name,
3️⃣ Ask Bolt to "use the [icon name] from iconify"
4️⃣ Spread the word so everyone can have this superpower

Did you know you can start a Bolt project by adding
`?prompt=` to the URL like this?
💡 #bolttip
It also allows for all kinds of cool lightweight integrations with Bolt; e.g. you can dynamically create a prompt in your app or website — then open Bolt already running it! 🤯

💡Bolt Tip:
For every change, the AI recreates the whole file — even if only 1 line needed updating!
Turn on the experimental "Diffs" setting to make Bolt output only changes to the necessary lines.
This results in even 10x faster updates and -20% tokens reduction!

This will not only make it easier on the eyes, but also help you find it on Your Chats list.

This is coo: with Gemini Nano you can have your own AI little model on the machine without needing anything other than the browser (feature flags needed tho!).
Just used @bolt.new to try it and made a simple ai chat:

Fun fact: in a consumer market, the CE mark seen on products in Europe is often associated with compliance to health and safety standards required to sell products in the EU, but it can also mean "China Export," which is likely just a coincidence.

Within a single prompting session, I usually use the "Rollback to checkpoint" feature.
When I wrap a prompting session for the day with something that works well, I'll sometimes open the project in StackBlitz and _fork_ the project — making a sort of milestone checkpoint.

If you want to ensure a specific *value* or part of the UI doesn't get changed by the AI:
1. Select that part in the code
2. Click "Ask Bolt"
3. Prompt: "Extract this to a separate file"
4. Right click on that new file and choose "Lock file"

As your app grows, a lot of stuff ends up in the App.tsx file. When this happens
💡 Ask bolt․new to extract the logic and structure into smaller files.
This will make:
- subsequent updates faster (and cost less tokens!)
- the code easier to analyze
- targeting & locking more precise

I won't lie; I was giving bolt about 40% chance of nailing this crazy prompt on the first try..
Yeah, it worked.
Yeah, it worked.
![the prompt: I've described the SearchResponse api in the openlibrary.types.ts file. Now, when we get search for the book, instead of displaying the json of the response, look through the "docs" array to find an object with "seed" property. In that "seed" property look for the value that starts from "/books/". That value will be the path to get details of the book (sth like openlibrary.org/books/[someid].json - note that you need to append the ".json" to the end).
Fetch that url. It will return a json of the structured described in as BookResponse in that same types file.
Display the description.value and the list of subjects.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:luozjflro3n7blsuhpmkzqod/bafkreifbbkpdqzog6udm2mhdofedum5rdcv22whx457bgw3kvbwrtoqjyi@jpeg)
