StL: "calioPY (cPY) is Open Source, cross platform software that lets you visualize, organize, publish and collaborate on calculations, clearly and simply. The software (approximately 1 kSLOC) uses a light-weight (21 tags), Python-based markup language (ASCII) that connects an extensive library of Python scientific, engineering and document processing software (over 1000 kSLOC). Procedures in cPY can be written with any text editor. Calculation output is in PDF. CalioPY knows how to evaluate and format math expressions and statements, (ascii inline, LaTex), calculation output, figures, tables, plots, create sketches, embed Python code, control the display of results, assemble PDF documents, and apply calculation page headers and title blocks. The program is designed to work within the Leo outliner, with the calioPY source code and libraries of calculation procedures both organized in the same Leo outline. This feature encourages modifications for specific needs and overall program improvement. It runs on Windows, thumb drives (Windows) and Linux (Kubuntu)."

JJinuxLand: Python Werkzeug: "I just finished the Werkzeug tutorial, and it looks pretty good.

Werkzeug started as simple collection of various utilities for WSGI applications and has become one of the most advanced WSGI utility modules. It includes a powerful debugger, full featured request and response objects, HTTP utilities to handle entity tags, cache control headers, HTTP dates, cookie handling, file uploads, a powerful URL routing system and a bunch of community contributed addon modules.

Werkzeug is unicode aware and doesn't enforce a specific template engine, database adapter or anything else. It doesn't even enforce a specific way of handling requests and leaves all that up to the developer.

Werkzeug is most useful for end user applications which should work on as many server environments as possible (such as blogs, wikis, bulletin boards, etc.).

Having coded applications in Aquarium, Django, Pylons, Ruby on Rails, Zope, Plone, etc., I've been fascinated by the idea of an anti-framework. A framework establishes the flow of the application and calls your code at certain points. That's the opposite of a library. A library lets you call its code whenever and however you want. Werkzeug is a collection of libraries."

Mike Coyle’s Weblog » Blog Archive » My PM Network Interview, or Tales from the Cutting Room Floor: "8) What ways can small teams work most effectively to accomplish big tasks?

There are four aspects that drive small-team effectiveness: Planning, Process, Automation, and Asset Management.

* Planning: Small teams need to focus their efforts on understanding how the key moving parts of their project fit together so that they can proactively categorize and manage delivery risk. This is far more important than trying to optimize the workload balancing in your project plan, since you’re not trying to distribute lots of work among interchangeable resources on a large team.
* Process: Small teams should maintain strict adherence to a lightweight process. Individual heroics are not scalable nor predictable over time. Even small teams need to play by the book, but they need to make sure that it’s the right book for them.
* Automation: Small teams need to maximize the amount of work that they don’t do, and focus their efforts on the important stuff. If work cannot be avoided, it should be automated. Computers are really good at doing predictable stuff really fast.
* Asset Management: Small teams should manage their important data using some sort of version control mechanism. A good version control syste"

Publicize PyCon - PyCon 2008 - Chicago - A Conference for the Python Community: "PyCon 2008

March 14-16, 2008

http://us.pycon.org

PyCon 2008, the sixth annual community conference for the Python programming language, comes to Chicago this year. The conference takes place March 14-16 at the Crowne Plaza Chicago O'Hare Hotel.

A rich schedule is being planned, including presentations, keynotes, Lightning Talks, an exhibition hall, and the hands-on Python Lab. Plentiful Open Space has been set aside for Birds-of-a-Feather sessions and other unscheduled 'unconference'-style activity. Several tutorials and talks are designed for new Python users and new programmers specifically.

The conference will be preceded by a day of intensive tutorials (March 13). Afterward, four days of development sprints (March 17-20) will bring participants together for face-to-face cooperation to advance several Python open-source projects.

PyCon attendance grew 44% from 2006 to 2007. PyCon 2008 has already set records for number of talks, tutorials, and sprints scheduled.

Registration is open now. Early-bird registration rates ($400 corporate, $220 hobbyist, $125 student) are available through February 20.

About Python:

Python is a dynamic, open-source programming language suited to many kinds of software development. TIOBE named Python the fastest-growing programming language of 2007. Python is particularly recognized as a valuable language for education. Its ease of use allows quick start-up and progress, yet it also encourages good long-term programming habits and style. Its clear, readable syntax makes cooperation between students and instructors easy. Thanks to its broad capabilities, rich libraries, and vigorous community, Python can continue to be a student's language of choice long after moving from beginner to expert. Python code can run on Java and .NET platforms through the Jython and IronPython implementations.

Python Package Index : virtualenv 1.0

Python Package Index : virtualenv 1.0: "virtualenv is a tool to create isolated Python environments.

The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into /usr/lib/python2.4/site-packages (or whatever your platform's standard location is), it's easy to end up in a situation where you unintentionally upgrade an application that shouldn't be upgraded."
