The control messages are transmitted via CAN bus

https://en.wikipedia.org/wiki/CAN_bus

The exact message content and protocols are reverse engineered.

Some cars use FlexRay instead of CAN bus but that has only experimental support.


Flexray is supported only on Audi on a specific Flexray-canbus integration board that was just end of lifed and Comma has no desire to support other boards. It was a proof of concept for anyone wishing to implement the same

Since this talks about sleep quality I want to add something that was almost unknown to me for over 30 years. Smartwatches AFAIK don't have CO2 sensors. It seems to me though, that that would be extremely useful for sleep quality tracking. I have just a couple of years ago found out that CO2 levels are having the highest impact on my sleep quality besides temperature. I can highly recommend getting a CO2 sensor to get a good feeling for that effect. Also understand how much air is available in your room and how much CO2 your body produces per hour. I totally underestimated this until I was able to measure it. In a small sleeping room with closed doors the amount of CO2 will reach unhealthy levels at the end of the night.

I'll also add in getting a standalone sensor (I went with Aranet) gave me insights into this was well, as a non smart watch wearer

At the end of the day you often need to consider the energy efficiency of a system which is also reflected in the cost of operating it. For use cases where this is relevant the suggested MCP approach potentially offers large benefits compared to what's probably meant here by "AI". However, the disadvantages of public access discussed in other threads need to be considered as well, therefore, I expected this only to be used for certain niche use cases. Testing and retro fitting non-public websites come to mind.


Once we have the thing working, optimization can come later.

Also MCP is not really optimal. Every prompt in a sequence of chat gets an injection of MCP capabilities. Its just simply not scalable with lots and lots of MCP servers. Not to mention the protocol changes every month and breaks things.

Furthermore, you can already do MCP like behavior, in a better way, on pretty much any model by basically writing a wrapper around the chatbot and using a system prompt which guides it to print specific text (like "action:load file"), and the wrapper can detect that text and inject the prompt. I have an agent that runs at home using this, which I also use to self improve and define actions on the fly - I ask it to write code, it writes code, then the wrapper takes that code and makes it part of the library and appends it to the system prompt on every new chat.

The point is that we should be able to take the latter, and build something that can do this automatically. Once we have the full loop complete, then we can optimize it down to minimum compute.


I never hated on Signal, on the contrary I recommend it too many people but I can say that the energy consumption on Android is in many cases abysmal for multiple years now and related issues in the Github issue tracker are being ignored. This is for me unacceptable for someone claiming to build high quality software and accepting my donations.

I wonder if what you describe is kind of the reason for this.


This Ian guy's shoe-tying tip you've linked is one of the most universally useful life-improving pieces of knowledge I have, which I try to evangelize to anyone I know who will listen. The only facts whose impact comes close are mostly household tips:

- cheap liquid dishwasher detergent including in the prewash cup instead of costly pods that deprive the prewash cycle of soap

- Put bleach in the washer's bleach dispenser and use hot water for any light sheets, no, it doesn't hurt prints or fade light colors

- cook anything you can fit in the air fryer to decrease total time ~70% vs an oven

Why would I want to cook my milkshake?


Nice.

Feature request: In the top/overview view I would like to be able to tap on each room and then the pivot point should move to the center of that room. After a double tap or tap on the top view button the pivot point should move back to the apartment center point. This will help zooming easily into each room from above.


Yeah, nice notice. I believe I will find time to implement such or similar features with the future updates.

I like this one much better https://youtu.be/RKfG3lWCZ80 at 4:20 onwards. Also explains the difference between slip and skid.


I did this back in the day using a ublox LEA-M8F module for my PhD work following the instructions posted here: http://www.opendigitalradio.org/lea-m8f-gpsdo I also experimented with RTK which this module is capable of. Now there's probably a more up to date ublox module available which could provide even better results using multi frequency GNSS etc.


Thanks. Does the USRP B200 know how to timestamp individual samples? Or I guess just one sample, the rest is easy.
