xAuth is Now Working for Me
The good news: I got xAuth working against Twitter this morning - my mistake was stupid - you have to double encode things, and I wasn't doing that. So that's good. The bad news?
This server (and the one over at Cincom) is running on VW 7.6. My first try at backporting ran into a number of small problems, so I've decided to take the other route: updating the servers to 7.7.1. It's probably a good idea anyway :)
XAuth Progress
I finally figured out what I've been doing wrong with the base access token requests - you have to toss an ampersand at the end of the consumer secret. Small thing, but it was the dumb thing I was forgetting. Now I'm looking at making API calls, and that looks kind of painful - you have to embed the API call into the xAuth signature, and the arguments for that need to be sorted. Which makes the whole thing way more painful than it needs to be.
Anyway, if I have time over the weekend, I think I'll have this working against Twitter.

Between Smalltalk TV, PharoCasts, and the Smalltalk Daily work I do, there's a ton of video tutorial content for Smalltalk out there now.

Network Simulation in Smalltalk
Bernard Pottier sent me an update on the network simulation stuff I saw last year at ESUG:
a simulation for a bus encountering networks of wireless sensors that could be installed on bus stop, and computing on the fly on these networks (bounding box)
a similar simulation for a virtual boat reproducing the Azenor navigation in a distribution of sensors along the shore.
It's a pretty cool project, with the CUDA integration done by one of Bernard's students, Thibault Failler. Cool stuff!
Browsing a Store Repository
There have been some updates to the internals of Store in VW 7.1.1 and OS 8.2.1 - the database layer is all Glorp now. Aditionally, the UI has gotten a facelift. When you browsed code in a repository in past releases, you got the ugly (and very outdated) 5i browser. Now you get the RB, although it's in read-only mode. When you start a browse operaton, you'll see this:
Once the package or bundle loads (in this case, a bundle), you'll see this - I've expanded the tree:
Finally, after selecting a class and a method:
The whole experience matches browsing in-image code a lot better now.
