Syndicating trust? Mediawiki, WordPress and OpenID

Fancy title but simple code. A periodic update script is setting user/group membership rules on the FOAF wiki based on a list of trusted (for this purpose) OpenIDs exported from a nearby blog. If you’ve commented on the blog using OpenID and it was accepted, this means you can also perform some admin actions (page […]

Remote remotes

I’ve just closed the loop on last weekend’s XMPP / Apple Remote hack, using Strophe.js, a library that extends XMPP into normal Web pages. I hope I’ll find some way to use this in the NoTube project (eg. wired up to Web-based video playing in OpenSocial apps), but even if not it has been a […]

Apple Remote events – a quick howto

Anyone who has recently bought an Apple computer probably has one or more Apple Remotes. I have been learning how to access them. Conclusion: iremoted does 95% of what you probably need, and the discussion over on cocoadev.com tells you more than you probably wanted to know. My experiments are written up in a corner […]

Local Video for Local People

OK it’s all Google stuff, but still good to see. Go to Google Maps, My Maps, to find ‘Videos from YouTube’ listed. Here’s where I used to live (Bristol UK) and where I live now (Amsterdam, The Netherlands). Here’s a promo film of some nearby art installations from ArtZuid, who even have a page in […]

Quick clarification on SPARQL extensions and “Lock-in”

It’s clear from discussion bouncing around IRC, Twitter, Skype and elsewhere that “Lock-in” isn’t a phrase to use lightly. So I post this to make myself absolutely clear. A few days ago I mentioned in IRC a concern that newcomers to SPARQL and RDF databases might not appreciate which SPARQL extensions are widely implemented, and […]

Getting started with Mozilla Jetpack for Thunderbird (on OSX)

A few weeks ago, I started to experiment with Mozilla’s new Jetpack extension model when it became available for Thunderbird. Revisiting the idea today, I realise I’d forgotten the basic setup details, so am recording them here for future reference. I found I had to download the source from the Mercurial Web interface, rather than […]

Wolfram Alpha Interview

An interview with Xiang Wang of Wolfram Research in China, by Han Xu (Collin Hsu) of W3China fame. Interesting excerpt: Q: Since Wolfram|Alpha is dubbed ‘smarter’ than traditional search engines, I wonder how much AI techniques are actually employed in the system? How is inference done? What is the provenance of each fact/claim? And what […]

What kind of Semantic Web researcher are you?

It’s hard to keep secrets in today’s increasingly interconnected, networked world. Social network megasites, mobile phones, webcams and  inter-site syndication can broadcast and amplify the slightest fragment of information. Data linking and interpretation tools can put these fragments together, to paint a detailed picture of your life, both online and off. This online richness creates […]

Twitter Iran RT chaos

From Twitter in the last few minutes, a chaos of echo’d posts about army moves. Just a few excerpts here by copy/paste, mostly without the all-important timestamps. Without tools to trace reports to their source, to claims about their source from credible intermediaries, or evidence, this isn’t directly useful. Even grassroots journalists needs evidence. I […]

goo go opensocial

The Japanese portal / search engine goo, have gone live with their Shindig-based OpenSocial container. See example user page, goo labs site, developer’s kitchen and documentation (in Japanese). See also announcement from Eiji Kitamura on the shindig (Apache opensocial) list.

Rick Jelliffe on XML Schema

From the TAG list: XML Schemas is like using a Swiss Army knife to cook with. Most Asian kitchens get by with a handful of simple tools: chopsticks, hatchet, a good knife, perhaps even a spoon. But the logic of  the XSD WG is “Oh, the French need to make quenelles, we must have a […]

Site recovery

Busy sysadmin week. The main FOAF site is back, now hosted on Amazon EC2. Thanks to Stephane Corlosquet for all the time he spent fixing up the Drupal installation, after the recent server compromise. I’ve also moved over danbri.org (well, DNS is propagating), and migrated my blog into a completely fresh WordPress installation. The FOAF namespace […]
