CVXMOD – Convex optimization software in Python
by ogrisel
CVXMOD is a Python-based tool for expressing and solving convex optimization problems. It uses CVXOPT as its solver. It is developed by Jacob Mattingley, as PhD work under Stephen Boyd at Stanford University.
CVXMOD is primarily a modeling layer for CVXOPT. While it is possible to use CVXOPT directly, CVXMOD makes it faster and easier to build and solve problems. Advanced users who want to see or manipulate how their problems are being solved should consider using CVXOPT directly. Additional features are being added to CVXMOD beyond just modeling. These are currently experimental.
CVXMOD has a similar design philosophy to CVX, a convex optimization modeling language for Matlab®, and uses the principles of disciplined convex programming, as developed by Michael Grant, Stephen Boyd and Yinyu Ye.

Modeling Cars with HyperNURBS
by kruty
Though the Chevy tutorial is dated by current Cinema 4D standards, portions of it remain somewhat viable. On the other hand, many plugins available since version 8 was released make much of this tutorial extraneous. Some of the techniques it teaches, I no longer even use myself (and cannot wholly recommend that anyone else learn to model this way!) - especially when the current release of C4D (v9 ) has included many many more modeling features not covered here, which only make this method more cumbersome.

DBAzine.com: Trees in SQL: Nested Sets and Materialized Path
by ogrisel

Relational databases are universally conceived of as an advance over their predecessors network and hierarchical models. Superior in every querying respect, they turned out to be surprisingly incomplete when modeling transitive dependencies. Almost every couple of months a question about how to model a tree in the database pops up at the comp.database.theory newsgroup. In this article I'll investigate two out of four well known approaches to accomplishing this and show a connection between them. We'll discover a new method that could be considered as a "mix-in" between materialized path and nested sets.
