It's interesting talking with people who are watching the US slide deeper and deeper into unsustainable debt while ticking off just about everyone else in the world. There's talk of massive recession, complete devaluation of the dollar, and basically a collapse of what passes for society down there.

The problem, of course, is that as ...

"So," figures I, "really should have at least some user authentication in the SIP server." Little did I realise that the Twisted code, while it supports authentication quite simply on the server, doesn't seem to have any code on the client side.

That is, the server can handle a client that knows how to authenticate, ...

AFAICT, the SIP protocol has no agreed upon conventions for registering display-names or other meta-data. That is, while you can attach display-names to just about every URI, there's nothing stating which URI's display name should be considered canonical when parsing a registration request. For now I'm assuming I should display the contact field's display name. ...

Have discovered why it is that the dratted x-lite refuses to log in to my registration server despite the fact that clients written in Twisted work perfectly well. x-lite automatically searches for and finds the NAT firewall, then configures it's return address as the address of the firewall. Result is that the registration server responds ...

I decided after work on Friday to do no "real" (i.e. needed) work this weekend. So far the 3D Software Collection has absorbed just about every dram of time for the weekend. Mostly just in tracking down projects, checking licenses, tweaking the display format, that kind of thing. I had to stop myself a couple ...

Using Python for 3D programming is actually a fairly common thing, but it's difficult to see that if you don't have a collection of projects somewhere that you can browse.

I put together a partial list after the last PyCon, but it was on a Wiki I didn't control, and it just wound up turning ...

As expected back when we were solving the Pernicious Influence of Puzzles, writing a script to generate all permutations of a word from a given word-list was a pretty trivial endeavour. Applied to our TRANSIT challenge the computer came up with a few we missed...

The ones I feel bad about:

artist
stain
taint ...

For the SIP project, discovered that Shtoom is, in fact, a user-level client... in other words, a Soft Phone. We need far less code than that for our project, in fact, it's all available from core Twisted.

Did a spike test creating a Proxy/Registration-server and a client to log into it in about 30 lines ...

One of the things I do to try to make PyOpenGL newbie friendly is providing sample code links directly from the PyOpenGL man pages to files from various projects which use the discussed function/constant.

This has proved very successful... so much so that we almost never get questions regarding how to use any given function/parameter. ...

Wound up unable to get to sleep until 7 or 8 in the morning. Then was woken up at 10 or so. Have been largely non-functional all day as a result. Began implementing the performance changes. The storage, calculation and retrieval is all working... now I just need to get it hooked back up to ...
