Not an RTOS as is commonly understood but RTIC is nice. I think originally developed for robotics.

Vipassana style meditation (minfulness) should always be combined with Metta (lovingkindness), especially for westerners.

That's the advice I keep seeing.

Vipassana is insight meditation, not mindfulness and not really appropriate for beginners. The closest equivalent to mindfulness would be concentration, or samadhi.

One of the core practices of insight meditation (Vipassana) is to be mindful of your inner thoughts, like through "noting", and observe them through the lenses of the 3 characteristics. You use one-pointedness concentration (Samadhi) to tune into these thoughts. You can also do Samadhi without Vipassana, as many yogis have, but you cannot do Vipassana without a baseline concentration ability. Some people use mindfulness meditation and Vipassana interchangeably, but it is not entirely accurate, yeah. Mindfulness is only one exercise of the broader insight meditation (Vipassana).

Yep...

Funny how nobody addresses the main point, only that my 1-sentence executive summary is not accurate :-)

Main point is: if you start doing mindfulness exercises, you will eventually get into insight territory, and without a cushion of compassion this can mess you up.

Not accurate at all, mindfulness and samadhi are two different factors in the eightfold path

Ha!

Cool project. I have been on the lookout for something like this.

The idea of exocortex seems to be something that many people want, and almost universially re-invent because the way in which structuring makes sense is different for everyone. I like the approach of making it modular so people can pick and choose parts and do their own integration.

What I learned from thinking about this problem is that this kind of integration is really hard and almost impossible to tackle without an evolutionary approach, and it made me go meta and focus on incremental development of the integration layer first. My interpretation of the idea of exocortex might be a bit different in that the focus is not so much about information per se, but more about systems that interact with the physical world. Here's a writeup in case anyone is interested in where it took me: https://github.com/zwizwa/erl_tools/blob/master/doc/exo.org

SEEKING WORK. Embedded Software / DSP / Test Automation / Code Rescue

I can bridge low level and high level work.

I travel frequently between Kalamazoo, MI and the Leuven/Brussels area, so remote+visits preferred. CV and contact info at http://zwizwa.be?hn

Currently looking to fill a small gap (weeks). I'm a quick starter.

Looking for a longer term 50% FTE commitment as well.

Past and current projects are mostly in the field of embedded systems: ASM, C, C++, Rust, on bare bones uC, RTOS and Linux, various architectures. I've ventured into simple analog circuit design and FPGA work on ice40, but my main field is software.

I do code rescue, code cleanup, prototype firmware refactoring. If you're familiar with embedded software you know what this is about.

Apart from the low level exposure, I've had a good dose of Functional Programming in the last 15 years. I use Erlang on embedded Linux, and Haskell and Racket for validation and code generation.
