GeographicLib is a small set of C++ classes for performing conversions between geographic, UTM, UPS, MGRS, geocentric, and local cartesian coordinates, for gravity (e.g., EGM2008), geoid height, and geomagnetic field (e.g., WMM2010) calculations, and for solving geodesic problems. It is a suitable replacement for the core functionality provided by geotrans. The library is licensed under the MIT/X11 License; see LICENSE.txt for the terms.

The argparse module was added to Python 2.7 as a replacement for optparse. The implementation of argparse supports features that would not have been easy to add to optparse, and that would have required backwards-incompatible API changes, so a new module was brought into the library instead. optparse is still supported, but is not likely to receive new features.

Processing is an open source programming language and environment for people who want to create images, animations, and interactions. Initially developed to serve as a software sketchbook and to teach fundamentals of computer programming within a visual context, Processing also has evolved into a tool for generating finished professional work. Today, there are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning, prototyping, and production.

Auto Complete Mode is the most intelligent auto-completion extension for GNU Emacs. Auto Complete Mode renews an old completion interface and provides an environment that makes users could be more concentrate on their own works.

Welcome to this introduction to newLISP! You'll find newLISP easy to learn and powerful, combining some of the power and elegance of classic LISP with the facilities of a modern scripting language, such as regular expressions, network functions, Unicode support, multitasking, and many others.

PyEphem provides scientific-grade astronomical computations for the Python programming language. Given a date and location on the Earth’s surface, it can compute the positions of the Sun and Moon, of the planets and their moons, and of any asteroids, comets, or earth satellites whose orbital elements the user can provide. Additional functions are provided to compute the angular separation between two objects in the sky, to determine the constellation in which an object lies, and to find the times at which an object rises, transits, and sets on a particular day.

Emacs is a huge beast. It can read email, play tetris, act as a file manager, display google maps, and even edit videos. It has support for many, many programming languages and has many features related to programming. Unfortunately, emacs doesn’t have a full programming environment for python out-of-the-box.

Armadillo is an open-source C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use. Integer, floating point and complex numbers are supported, as well as a subset of trigonometric and statistics functions.

Together with its library routines it serves as a tool for data analysis and visualization in such disciplines as astronomy, geosciences and medical imaging. GDL is free software licensed under the GPL. GDL is developed by an international team of volunteers led by Marc Schellens - the project's founder

HPC Techreport
A brief introduction to Python (for scientific computing)

Software is a cornerstone of science. Without software, twenty-first century science would be impossible. Without better software, science cannot progress.

The Endeavour
The blog of John D. Cook

This tutorial assumes no previous knowledge of scripting or programming, but progresses rapidly toward an intermediate/advanced level of instruction . . . all the while sneaking in little nuggets of UNIX® wisdom and lore. It serves as a textbook, a manual for self-study, and a reference and source of knowledge on shell scripting techniques. The exercises and heavily-commented examples invite active reader participation, under the premise that the only way to really learn scripting is to write scripts.

EmacsRookie is like a personal diary from Samuel Tonini about his daily adventure with emacs. Fascinated about the power and capabilities of emacs and the community which stand behind this flagship, he decided to create a spot where he will discover these hidden treasures.

We’re a group of Linux administrators that wanted a place to share bash shell scripts and Linux command tutorials with other Linux users. BashShell.net is the site we’ve chosen to index tutorials, tips and shell scripting lessons as we come across them.

Parse RSS and Atom feeds in Python. 3000 unit tests. Open source.

PyChecker is a tool for finding bugs in python source code. It finds problems that are typically caught by a compiler for less dynamic languages, like C and C++. It is similar to lint. Because of the dynamic nature of python, some warnings may be incorrect; however, spurious warnings should be fairly infrequent.

PP is a python module which provides mechanism for parallel execution of python code on SMP (systems with multiple processors or cores) and clusters (computers connected via network).

This program, given a source file, produces a document with syntax highlighting.

Flask is a microframework for Python based on Werkzeug, Jinja 2 and good intentions. And before you ask: It's BSD licensed!

LifeWiki is a wiki designed with the hope of collecting all information about Conway's Game of Life together in one place. It contains a comprehensive catalogue of patterns as well as a glossary and general information about the game.

Cython is a language that makes writing C extensions for the Python language as easy as Python itself. Cython is based on the well-known Pyrex, but supports more cutting edge functionality and optimizations.

Naïve upsampling of pixel art images leads to unsatisfactory results. Our algorithm extracts a smooth, resolution-independent vector representation from the image which is suitable for high-resolution display devices

Ropemacs is a plugin for performing python refactorings in emacs. It uses rope library and pymacs.

The purpose of this web site is to act as a community knowledge base for performing astronomy research with Python. It provides lists of useful resources, a forum for general discussion, advice, or relevant news items, collecting users' code snippets or scripts, and longer tutorials on specific topics. The topics within these pages are presented in a list view with the ability to sort by date or topic. A traditional "blog" view of the most recently posted topics is visible from the site Home page.

For Python programmers, I've got some suggestions on how to write a main() function that's easy to invoke in other contexts, e.g. from the interactive Python prompt when you feel like experimenting.

So, instead I went and did a little rewrite of it. In a simple and pure bash script. I duplicated the functionality of the daily mode (fetch images per day and put them into a daily subdirectory, create html files for them) and didn’t bother with the “fetch a random strip one” as I never used that. Turned out at 276 lines of shell script that can even fetch alt/title and not break on funny characters in them, yay.

ECB stands for "Emacs Code Browser". While Emacs already has good editing support for many modes, its browsing support is somewhat lacking. That's where ECB comes in: it displays a number of informational windows that allow for easy source code navigation and overview.

Pymacs is a powerful tool which, once started from Emacs, allows both-way communication between Emacs Lisp and Python. Pymacs aims Python as an extension language for Emacs rather than the other way around, and this asymmetry is reflected in some design choices. Within Emacs Lisp code, one may load and use Python modules. Python functions may themselves use Emacs services, and handle Emacs Lisp objects kept in Emacs Lisp space.

Random musings about programming, software, technical interviews, and of course Emacs - a tip every week for new and experienced users.

After I’ve covered basic plotting using matplotlib in this part I’ll show you two ways to display histograms of some data.

This talk will start with a general introduction into Emacs and Org-mode. It will then step by step introduce the different concepts and applications of Org-mode using the example of a simple project. We will demonstrate how to brainstorm, plan and track a new project, how to take and organize notes, and how to turn the notes in web pages, printed reports and presentations. The talk is intended to be accessible to an audience without programming experience, but will also contain teasers for people with programming experience.

IDLWAVE is an add-on mode for GNU Emacs and XEmacs which enables feature-rich development and interaction with IDL®, the Interactive Data Language, produced by ITT Visual Information Solutions. It provides a compelling, full-featured alternative to the IDLDE development environment bundled with IDL.

If PDF is electronic paper, then pdftk is an electronic staple-remover, hole-punch, binder, secret-decoder-ring, and X-Ray-glasses. Pdftk is a simple tool for doing everyday things with PDF documents.

Wer als Schüler, Student, Ingenieur oder Wissenschaftler Datenreihen und mathematischen Funktionen darstellen will und über elementare Python-Kenntnisse verfügt, der sollte sich diesen Artikel einmal genauer ansehen.

In this article I present some special astronomical scripts created for Google Earth, Google Sky and Twitter. These 'hacks' are examples of the ways in which such tools can be used either alone, in on conjunction with online services. The result of a combination of multiple, online services to form a new facility is called a mash-up. Some of what follows falls into that definition. As we move into an era of online data and tools, it is the network as a whole that becomes important. Tools emerging from this network can be capable of more than the sum of their parts.

The goal of this book is to teach computational scientists how to develop tailored, flexible, and human-efficient working environments built from small programs written in the easy-to-learn, high-level language Python.

The focus is on examples and applications of relevance to computational scientists.

There are no external image files or anything, everything is rendered with Javascript using either canvas elements or old fashioned div-making tactics (for IE).

rawdog is an RSS Aggregator Without Delusions Of Grandeur. It is a "river of news"-style aggregator: it uses feedparser to download feeds in RSS, Atom and a variety of other formats, and (by default) produces static HTML pages containing the newest articles in date order. For example, rawdog's default configuration produces output that looks like this:
