And he comes up with an interesting solution: expiration dates in electronic files. This would stop the files from existing forever and flooding us and the next generations with gigantic piles of mostly useless or even potentially harmful details.

While lxml has some excellent benchmarks about the speed of lxml.etree vs. ElementTree, I wanted to run some tests that were as close as possible to my own use case (fairly simple multi-megabyte XML files).

Basic logging of errors to text files and system logs is an old technique, but not very flexible. In this post, I introduce a logging system for the Python programming language. This system, while it borrows ideas from other systems, is not a port of anything but an independent implementation for use by Python developers.The logging package has been part of Python since Python 2.3 (released in 2002).

ScriptServer is a minimalist application server, handling both GET and POST requests, including multipart/form-data for file uploads, HTTP redirections, and with an in-memory session management. It can run Python scripts and template files using the standard string substitution format

Most web pages include resources that change infrequently, such as CSS files, image files, JavaScript files, and so on. These resources take time to download over the network, which increases the time it takes to load a web page. HTTP caching allows these resources to be saved, or cached, by a browser or proxy. Once a resource is cached, a browser or proxy can refer to the locally cached copy instead of having to download it again on subsequent visits to the web page. Thus caching is a double win: you reduce round-trip time by eliminating numerous HTTP requests for the required resources, and you substantially reduce the total payload size of the responses. Besides leading to a dramatic reduction in page load time for subsequent user visits, enabling caching can also significantly reduce the bandwidth and hosting costs for your site.

In this book, we'll be using the freely available IBuySpy Portal as a starting point for our intranet development. We'll look at both why we are modifying an existing intranet application rather than creating our own, and why we choose the IBuySpy Portal in particular. Once we have covered the basics, we'll take a tour of its features, looking at the files and types it consists of, how they function and fit together, and general principles behind the site. Finally, we'll take a brief look at how security is handled.

RichFLV let`s you edit flv files.

A new service for creating simple shareable paper booklets: publishing at your fingertips. Bookleteer uses Proboscis' unique Diffusion eBooks and StoryCubes formats to create PDF files that can be downloaded, printed out and made up.

The modules in the Python standard library don't provide a way to upload large files via HTTP without having to load the entire file into memory first.

poster provides support for both streaming POST requests as well as multipart/form-data encoding of string or file parameters

The hyperdata Address Book project being developed here is meant to be the equivalent for foaf that BlogReaders are for RSS. It is a specialised Semantic Web browser that follows foaf documents around the web, building a distributed open social network. It is also a foaf editor, which you can use to publish your foaf files to an ftp/scp server.
