Developing Rich Internet Applications (RIA’s) by combining Flex with Turbogears.

Fred Sells did this presentation for the OrlandoJUG. Here's the writeup and I'll attach the source code to this discussion so we can work through it. Stay tuned for the code!

"Flex is a (mostly) open source IDE from Adobe that uses seamlessly combines XML layout definitions with ActionScript programming to create Flash applications. A fairly robust application can be built using the xml layout definitions with minimal ActionScript programming. Flex applications support a wide variety of server-side API’s, including XML and JSON.

Turbogears is an open source web framework written in Python that is similar to Ruby on Rails. Turbogears supports all the major RDBMS’s and uses either SqlAlchemy or SqlObject to provide Object-Relationship-Mapping (ORM) to simplify server side coding. A basic web application can be implemented in just two files: a database model and a controller containing the business logic. Although Turbogears is primarily used with any one of several HTML templating engines, it also supports JSON."

This presentation will focus on rapid development of RIA’s using Flex on the client side with static XML files to simulate server-side responses, then migrate to JSON with a Turbogears backend."

Cloudflare’s Post-Quantum GeoKey Manager Enters Closed Beta Without Attribute-Based Encryption

Cloudflare has moved a post-quantum rebuild of GeoKey Manager into closed beta, guarding geo-fenced keys with hybrid ML-KEM-768 and X25519 instead of the attribute-based encryption used since 2022. Keys live only in kernel memory on verified regional servers, and any failed check rejects the request, a fail-closed choice practitioners ask could cause a regional outage. GA is planned for Q1 2027.
