Cara ready to be tried externally!

Wed 29 April 2015

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 …

Why only internal use?

Sat 06 December 2014

Because I have 3 tests covering 67% of the code base and my only docs are blog posts. If you're way more adventurous than I am, the code is available at for your daring consumption.

Cara ready for internal use!

Sat 06 December 2014

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.

import cara

class MyStruct(cara.Struct):
    field1 = cara.Field(name='field1', type=cara.Int32)

However, this causes various problems due to capnp allowing use of types declared later …

Cap'n proto alternative RPC API in the works

Wed 26 November 2014

Having started a new project that requires RPC, but without the benefits (and restrictions) imposed by my previous employer, I've gone on a detour towards building another RPC layer. However, knowing that building the entire layer from scratch is both a waste of time for me and would just add noise to any community I sent this to, I decided to only create the missing parts and rely on existing technologies wherever I could.
