For large data centres a big industry player estimated costs of £22 / GB / Month = £250k / TB / Year. Majority of this was hardware and energy costs (not costs of human sysadmins). This seems quite a lot. However, Amazon S3 quote for Europe (cheaper for US):
Storage $0.18 per GB-Month of storage [...]I’ll be giving a talk at Open Tech 2008 on Saturday (5th July) about some of the work I do at the Open Knowledge Foundation. The talk is entitled “Opening Data†and its rough subject is indicated by the blurb:
We all want more open data to analyse and mashup be it for [...]
A new version (v1.2) of my python script for converting markdown to latex is now done. markdown2latex (renamed from mkdn2latex) has been extensively refactored to become a proper python-markdown extension. This means it can be used seemlessly alongside plain markdown conversion, as well as independently whether as a module or, in its classic form, [...]
Distributed versioning systems (VCMs) have now matured to the point that I’ve been planning to switch from subversion for quite a while — at least for own personal repositories where there are no coordination issues. Having chosen mercurial (hg) as my DVCM of choice the next step was to actually convert. While there is [...]
I record briefly my experience resolving this issue in case it helps others. As background I note that I use svk to allow local commit and replay for some of the subversion repos I use and over the last week I’d started encountering problems when trying to svk sync on one of these receiving the [...]
An (ongoing) summary of my experience with some of the utilities available for plotting from a python perspective.

I’ve been thinking about how to have a versioned domain model similar to the way we have versioned filesystems (e.g. subversion) for over two years. Over the last few months whatever bits of free time I’ve had have gone into developing a prototype built on top of sqlobject and I’ve now got a rough and [...]
I’ve updated mkdn2latex the python script which converts markdown to latex (see also the original release announcement). Changes include:
Support for markdown code blocks and html pre/code blocks generally using latex verbatim Verified compatibility with markdown 1.6 A few minor bugfixesAnnotation means the adding of comments/notes/etc to an underlying resource. For the present I’ll focus on the situation where the underlying resource is textual (as opposed to being an image, or a piece of film or some data). Various things to consider when implementing an annotation/comment system:
Addressing and atomisation: Are annotations specific to particular [...]
Following my release of the markdown to latex script I’ve had a few enquiries from people asking about integrating mathematics with markdown generally (e.g. for web output as well as for output to latex). I’d already been using mathematics in markdown and then processing to html before I wrote the mkdn2latex script and in [...]
