Here's a simple graphic application which is built on the graphicApp.py framework. This isn't a beginner's hello world. This is the final project kind of program, and only for a student with some trigonometry background. The basic trig isn't too complex, but would require rather detailed documentation to motivate …

Background.

The suggested environment for learning to program using graphics instead of text was LiveWires . This includes a curriculum and associated product, making it a tidy package.

There are a number of alternatives, however.

• Python includes tkinter , section 20.1 of the Python Library Reference, v2.5.
• Python includes turtle …

Physical Tuning.

"...databases can be tuned by creating appropriate indexes, removing others, modifying the physical database schema to suit the most common types of queries, etc. So it isn't clear whether the PL/SQL figure could be better if the database was optimised by a good DBA."

While a good …

While the question of speed came up recently, it ties in to a long-standing position of mine. I ran some realistic benchmarks, and I'm much happier with my architecture now.

Background.

Years ago, at a Siebel conference, I heard a heretical comment. Specifically, they use the RDBMS as simple, flat …

Some additional Sugar notes recently appeared in "Plumbing Life's Depths ".

After attending PyCon, I polished up my GTK environment, reloading the current releases. Here's what I did to get a workable PyGTK on my various desktops.

The GTK Technology Stack

Here's an overview of the components of this stack:

1. GLIB …

Actually, the code looks like a clever expansion on my example, in PyCon 2007 (Revised) .

"But wait," you say. "Creating a pivot table in Python?"

Of course. Spreadsheets can create pivot tables from dimensionally normalized data. However, getting the data in this form is often challenging and if there is …

First, I'm really pleased to see a focus on end-user applications of Python. It seems like most of the Open Source Community likes to build infrastructure, operating systems, servers, frameworks and components. Maybe I'm looking in all the wrong places, but I have a soft spot in my heart for …

Things I learned at PyCon 2007 .

1. In the Open Source community, men outnumber women 571 : 22. I guess that's why I'm married to a sysadmin instead of a programmer.
2. While I already knew that programming was literature, I never really connected it with Rhetoric until hearing R0ml's keynote. If programming …

My approach to preventing IT insignificance begins with firing the good programmers, since they're saddled with low-value work to begin with. In order to see what that means, let's look at the three phases of an IT organization's collapse to irrelevance. Then we'll see why some specific reorganization steps can …

Here are some useful quotes:

• Andrew’s first law of career spotting: Accountants are people who, when confronted with a problem, think “I know, I’ll use [A spreadsheet]”. Now they have two problems.
• [A spreadsheet] is a great prototyping tool, just don’t let it anywhere near your production …
