9/11 tragedy pager intercepts.

The following are national US pager intercepts that cover the September 11 tragedy from 3am on the same day (Tuesday) until 3am the following day.

This way the world has a chance to objectively see how the tragedy progressed.

A full archive containing all the messages will be released on Thursday November 26 at the conclusion.

jQSlickWrap - Slick text wrapping for jQuery

by vrossign
To do this, it needs to have access to the individual pixels of the images it's operating on -- which is why for jQSlickWrap to work, you need to have a browser that supports HTML 5's new canvas element. Here's an overview of the algorithm: 1. If necessary, pre-load the image. 2. Determine the CSS styles for the image (float and padding). 3. Create a canvas element and set its dimensions to the size of the image plus its padding. 4. Draw the image onto the canvas in the top-left location. 5. Figure out the "background" color of the image by examining the pixel data at the top-left corner of the image. 6. Fill the canvas with this background color.

map butcher » Finding Reality

by karlcow

Recently I’ve been doing some ‘gardening’. You can see this clearly from these images on NearMap…. What’s really special about NearMap apart from the fact they are updating imagery more often than I am at home is that they have integrated OSM into their viewer and you can use their data to update OSM:

Protovis

by parmentierf & 2 others (via)
Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)! Although programming experience is helpful, Protovis is mostly declarative and designed to be learned by example.

futurelib / YeeRDF

by karlcow

Martha asks a number of questions about RDF in the article. Even the title is a question: "Can Bibliographic data be Put Directly onto the Semantic Web?" (Answer: it already is ) Martha is conducting an admirable gedanken experiment about the future of cataloging, creating her own cataloging code and trying to mesh her ideas with concepts coming out of the semantic web community. The article's value is not only in her conclusions but in the questions that she raises. In its unfinished state, Martha's thinking is provocative and just begging for further discussion and development.

Python Package Index : roles 0.6.0

by karlcow

Library for Role based development.

Pythonic implementation of the DCI (Data Context Interaction) pattern (http://www.artima.com/articles/dci_vision.html).

The big difference with mixins is that this role is applied only to the subject instance, not to the subject class (alas, a new class is constructed).

Roles can be assigned and revoked. Multiple roles can be applied to an instance. Revocation can happen in any particular order.

Livres dans le Linked Data | Figoblog

by karlcow

Finalement, nous avons discuté organisation et compétences (deux thèmes qui me tiennent fort à cœur ;-) car si nous voulons vraiment que le Linked Data ait un avenir dans les bibliothèques, il va falloir que différents niveaux d'acteurs s'y intéressent et s'y investissent. De ce point de vue, la désaffection de la profession pour les questions de métadonnées (yes, MARC c'est tellement has been) me paraît inquiétante.

Choisir les bonnes personnes.

Amazon RDS, MySQL, Hmm?

by marco
BTW if you follow their "use mysqldump" model for pushing data into the service, remember that --single-transaction will allow you to do a hot backup. There is no need to lock up your current database. I am still appalled at how few people know that. Years ago we should have renamed "mysqldump" to "mysqlbackup" and defaulted the settings for Innodb.
