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 …continue

Building a binary into your Python package

Mon 15 December 2014

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 …continue

Cara generation method changed; delayed

Mon 01 December 2014

Up until this week, cara had been outputting its schema files something like this:

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

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 …continue

pygame - "video system not initialized" error

Sun 09 October 2011

I got this error every time I tried getting an event in pygame, so I had just put a try-catch and hoped it would go away. Turns out, the init check is done for almost every pygame.key function too so I got stuck. I spent a lot of time …continue

Sun 02 October 2011

This problem has bugged me for a few years actually, I have tried over and over again to use a single file for all of a Django projects' python code. This has proved very possible as long as your project did not have models, because no tutorial or howto online …continue

Django (Simple) Template Maker

Fri 16 September 2011

I was recently building an app that takes an email template and sends it to a membership list, and thought that I should be able to allow the users to make the templates themselves. The templates that I had seen for the past 4 years for the emails have been …continue

Random weighted choice

Tue 30 August 2011

Many times I need to choose randomly from a list of 'neighbors' according to some weight assigned to them, and I'd like to share my technique. My language of choice is Python, but this technique should work in any language that has some sort of list and a random number …continue

Django + Twisted + IRC Server = django_ircd

Sun 27 March 2011

I've been working with Yardbird (Django + Twisted + IRC Bot) and I thought about extending the bot I use to do more than just log the one channel it's in. What if it logged all the channels? What if it was the main authentication route instead of O: lines and the …continue
