An Architecture for a hardware-software system II

This is our solution at Tonbo Imaging to the question I put up here.

Very broadly, I'll break our solution into:

1. The various components and gluing them together
A whole lot of Managers that handle various aspects of the software, the Views, a CommandParser, and MessageResponse Queue, all glued together by an internal RxBus - asynchronously sending messages from various threads to one another.

2. Device Capabilities + Autogen UI
Each camera broadcasts its capabilities, a json file containing a list of commands it can take. Each command contains its parameters, their datatypes and the list/range of values they can take. A lot of the UI is autogenerated from this.

3. Versioning
This was fairly tricky and we're still not 100% sure we're happy with what we have. We have to take care of the versioning between various components:
- camera OS ⇌ camera software
- camera software ⇌ clients
- camera software ⇌ web

4. Camera-Graphics-Display-Streaming 
I'll add the graphics library I made to this list. The above points do not highlight how the camera, display, rendering, and streaming are a subsystem of their own and how neatly we're able to make it work for us. In (1) I've simply overlooked this entire bit as one box in an ocean of other boxes. Read more about this on my website.

Finding My Parter

Finding my partner feels more like finding  my kind . I’m this mix of an Indian boy with Indian familial ties, but European hobbies and a European way of leading life. I've lived in both worlds for 15 years each. There aren't many that have seen and lived in both worlds, and experienced completely different ways of life. Maybe I am asking for too much, but I don’t understand why one wouldn’t. If I have high standards for most things that I do in life, why wouldn’t I hope or want my partner to think from the same lens? Here's my value system. Be generally optimistic. A positive, happy person whose baseline state is to lean towards an optimistic outlook towards everything in life. Be fit. If one is not physically fit, there's low chance they're mentally fit. Plus, being fit shows discipline and consistency. Be hard working. Everything in life is a project. From raising children, to picking up groceries weekly, to building a home. And no one wants to work with a lazy ...

Two Worlds, Two Lives

I’ve been in India for the past two months now, and for the first time in my life, I can imagine myself live here again. Nothing drastic has changed in my day to day life, nor in either of the nations per se, but maybe I’ve had enough time to experience the flip-side to know what India’s strengths are. I’ve always acknowledged how I get the chance to live in two different worlds. But this is the very first time I’ve realized I also lead two different lives each time I switch countries. For me, Germany is a nation where you put the self first - you learn about yourself as an individual. It’s also a country where you learn to live life in the way they show us in movies - walks in parks, play sports any time of the day, vacations in every season the climate has to offer, meetups at little cafes with chairs out on the street. Work is secondary, rarely one’s primary driver in life. Therefore, it is also rarely one’s identity. The country and the mindset is averse to change. The philosophy h...

Keeping Fit in India

I have a bold claim to make: As compared to Europe, it's much easier to get and keep fit in India. But it's far less likely. Easier because: Relatability In India, you can relate to the others' bodies. Everyone around you has the same body style, our carb heavy diet that causes so many of us to be skinny fat. And so when you go to a calisthenics gym, it really helps to be able to look around and see that a person who looks like you is fit . That shines hope, telling you that it is possible in the first place. In Europe, the same is counterproductive. Looking at the European's low body fat, tall yet muscular physique makes me think they're just born with it. (Which is not true. I suppose they really do have great genes, but their meat heavy diet and walkable/cycleable cities help with keeping fit). Food is easier in India. You know your food here. You know the spices we use and how it tastes. It's that familiar feeling of eating something you know, as opposed to...
