As anybody who's looked at Cara's capnp->Python conversion code, they may have noticed that I've taken a liking to C++ metaprogramming via templates. I started my initial foray into C++ back in '06 when modifying an existing codebase for a robotics competition. It didn't use templates, and for the …

After months of internal use without problems, we're ready to release cara for others to use. We would be very happy if others picked up cara and made it work for them. If you've been looking at the Cap'n Proto project but were hesitant to shoehorn it into your Python …

This past Saturday, two friends and I played AoE II HD (Age of Empires II HD) online. We played a semi-custom scenario one of them had made with the three of us as a team in the middle of the map against 5 Hardest computers, high initial resources and starting …

Recently, I was looking at the Wordpress Admin page for this blog and everything was responding slowly. I realized that Wordpress is overkill for this blog. I have under 100 posts spread over 7 years, averaging under a post per month, I don't need a full-blown blog engine.

I got my Bionic Bird in the mail recently, and I really wanted to start flying it. However, I only have Android devices, nothing that runs iOS, so the official channels were blocked.

Firstly, let me acknowledge this is a rare problem. So the lack of documentation I ran into is totally acceptable. The problem: I have a Python package that has a C++ component that isn't an extension, it's a binary. I wanted that binary to be on the PATH of users, but it's not a Python entry point, so the usual way failed while attempting to read the file as text.
So I did some hacking, and after a lot of attempts, I whittled the result back down to something that's actually quite reasonable. If I had ever seen a documentation page or blog post mentioning this is how you do it, I would have been able to just follow along and I would have been happy with the result. Sadly, there was none, so I'm writing it:

After about a month of work, cara (Cap'n proto Alternative RPC API) is finally ready for internal use for Chain Reaction Mfg's main project.
The features required are finally working (and tested): 1. Send raw data and structs over the wire (like everybody else). 2. Send interfaces over the wire in both directions. 3. Support a reasonable io event loop.
The second one is the most important (and unique) feature for me. It means I can call a function on a server that returns another function (or rather, a set of functions) as well as some data.
