I have older versions of litellm installed on my system - it appears to be a dependency for aider-chat (at least on NixOS)

In this case though, the new driver has the same license as the project it was based on and explicitly credits the original project

Protothreads are amazing, but really expose you to a lot of subtle bugs. I would not recommend them for any new projects if something like async rust or an RTOS are options.

Here's the chat session - you can expand the thought process and see that it tried a few things (hands misaligned with the keyboard for example) before testing the Dvorak keyboard layout idea.

I also found it interesting that despite me suggesting it might be a password generator or API key, ChatGPT doesn't appear to have given that much consideration.

I was concerned there might be sensitive info leaked in the browserbase video at 0:58 as it shows a string of characters in the browser history:

    nricy.jd t.fxrape oruy,ap. majro

3 groups of 8 characters, space separated followed by 5 for a total of 32 characters. Seemed like text from a password generator or maybe an API key? Maybe accidentally pasted into the URL bar at one point and preserved in browser history?

I asked ChatGPT about it and it revealed

    Not a password or key — it’s a garbled search query typed with the wrong keyboard layout.
    
    If you map the text from Dvorak → QWERTY,
    nricy.jd t.fxrape oruy,ap. majro → “logitech keyboard software macos”.

I switched to a candy-bar style dumb phone for a month and did something similar. My list was pretty much the same as the one in the article with a few small changes.

The most jarring was probably maps - other things like email, messaging etc could be delayed until I could reach a computer but not knowing how to get somewhere right now was problematic and required planning in advance.

I usually kept my smart phone in my car and did a sim swap on the occasion that I really needed it.

LLMs struggle more with embedded software due to the relative lack of examples in the training data compared to javascript etc. They also struggle more with visual reasoning tasks like the character example you provided.

For your first task - give it smaller steps along the way that you can validate. Provide context where possible (like docs for st7789, examples of other zephyr projects). Use Opus instead of Sonnet for tasks that are on the edge of it's capabilities like this. It will still make mistakes, be prepared for iterating on the design and providing feedback.

For your font example, you always need to validate the output of the LLM, but did it still save you time? If so then I consider that a win. If not, give it the task that it's good at (ie generating the surrounding code and definitions) and then fill in the font data yourself.

This is the best explanation I've found of the mechanics of pitch bending https://youtu.be/Fp-GxEaChr0?si=-E9uDTQx51gtnd9C

Essentially, match the size of the resonance chamber in your mouth to the note you're trying to bend to. This is different for every note you bend. You can find the right size by making "hissing" noises while breathing in (without harmonica) and matching the pitch.

Yes you're right. I'd assumed that tokio was used internally in the UI but from a cursory read it doesn't seem to be the case.

Could you elaborate on why using block_on wouldn't be an acceptable solution for users that want a blocking API?

I've seen Gemini Flash 2 mention "in the OCR text" when responding to VQA tasks which makes me question of they have a traditional OCR process mixed in the pipeline.

I wish remote build/deploy for Raspberry Pi was in a better state - it seems like a perfect fit for NixOS.

I've got x86 servers running NixOS that are deployed using Colmena, but it seems to fall apart when I add cross compilation into the mix.

dhon_ — Mon, 07 Oct 2024 00:49:41 +0000

Cars radios are battery powered so will continue to work during power outages, and large enough that adding an AM radio + antenna is not really an issue - unlike a mobile phone. Seems like a good way to ensure most of the population has access to emergency broadcasts.

Edit clarified car radios are battery powered

What would be an acceptable error rate for your use case?

There are situations where AI is good enough, other cases where you need more accuracy, and others still where you should be reading the reference directly.

AI is improving quickly though, and context windows will allow for summaries to be tailored to each end user.
