1. On Conferencing ...

    So far in 2016 I've been to LinuxConf, PyConAU and Compose, and if it hadn't been the same weekend as PyCon I'd have gone to DDD as well. I've also been along to plenty of smaller meetups including MelbDjango and BuzzConf Nights. So why all this relentless conferencing?

    Far down the vault a man was screaming. His fists were tightly clenched and he was screaming out imprecations against the humming computer.

  3. Credit Gateway Policies


    Jack Skinner and I were talking at BuzzConf on the weekend, and it turned out this is something we've both noticed and been annoyed by.

    Category: etc.

    From the "Ideas I'm Never Going To Implement Myself" bucket:

  7. The Selfish Secret: Logins Without Passwords

    Fri 27 June 2014

    Category: etc.

    Perhaps instead of looking at cookies as a proxy for passwords, we should be looking at passwords as a transport mechanism for secrets! The desired result is to share a secret key between the server and one or more browsers, and the password is merely a mechanism to prove the browser worthy of the secret ...

    An odd little one: I was compiling some older code on gcc 4.6 / Ubuntu 11.10 and it failed to make, with the traditional error:

    undefined reference to `sqrt'

  11. VRML: Very Odd.

    So the VRML rendering thing isn’t panning out so well. “Making the simple things simple by making the difficult things impossible”.

    We’re talking, here, about a language which has a clock, but no way to display the time. You can display strings on billboards, and the billboards even ...

  12. (sort of) First Class Classes in C#

    I find myself writing some C# code while still thinking in Python. One thing in particular caught me out … it seems, at first, that C# doesn’t have first class classes. This is annoying, because I’d started writing some device driver classes where each class is a type of ...
