CaptSolo :: All Blogs

Irish recording industry is forcing ISPs into disconnecting Internet users and censoring the Internet. This blog posts describes the problem and tells why it is a very bad idea:

• http://andyaz.ie/blackout-ireland/

These threats have led Internet users to start a protest movement called Blackout Ireland:

• Blackout Ireland blog
• #blackoutirl Twitter conversations - live updates

Blackout Ireland follows in the footsteps of the original #blackout
in NZ. They are fighting against a controversial censorship law that was
about to be introduced:

• New Zealand Internet Blackout - protests against the Guilt Upon Accusation law ‘Section 92A’
• NZ #blackout timeline shows a prime example of citizen activism

You may think that turning your Twitter avatar black may not have much effect. You may be wrong. Imaging the awareness that can be raised by such high-profile twitter users as @stephenfry when his >200′000 readers were wondering why his avatar was black (during NZ #blackout).

Update: Canada is emerging as another battlefront for online rights:

• Canada’s Quebecor (ISP) wants a three strikes approach that would terminate its own subscribers

Michael Geist writes in the article linked above:

“That any ISP could demonstrate such hostility toward its own customers provides a clear indicator of the utter lack of broadband competition in Canada and serves as a warning that the New Zealand fight could eventually make its way here.”

If you need to install Redland Python bindings on Mac OS X then one of the ways is to use MacPorts:

sudo port install redland-bindings +python25

It is just one command and all dependencies will be installed automatically. (Though I usually install python25 with a separate command)

There is a cost to this because MacPorts would compile its own version of Python and as a result the installation might take a while. This is due to MacPorts policy to install all the prerequisites.

Context: I was having issues installing Redland Python bindings on Mac OS X and it seemed that nobody around me had them working either. MacPorts turned out to be the easiest way to do this.

Claudia has extended our WordPress SIOC exporter and written up a nice report about it: Extended WP SIOC Exporter

She gave her permission to republish this report over here and would be happy to get your feedback.

I extended Uldis Bojars WP SIOC exporter to also export semantic metadata which are embedded in the HTML content of a Posting.

Why is this useful?

Semantic metadata embedded in the HTML of a posting’s content can reveal more information about the topic of a posting (i.e. about what a posting is about). Tools such as Structured Blogging (http://structuredblogging.org) or the Semantic Reblog prototype I am working on, embed semantic metadata directly into the HTML content of postings.

The WP SIOC Exporter relates at the moment the whole plain text of a post’s content with the resource representing the posting itself via the sioc:content property. The html representation of the post’s content is related with the resource representing the post via the content:encoded property. Additionally links are extracted from the post’s content and related with the post via the sioc:links_to property.

My extended version of the exporter also extracts images from posts’s content and relates them via the sioc:embeds property with the resource representing the post. If the image is a flickr image an rdf:seeAlso link is generated that points to the RDF description of the image obtained via Masahide Kanzaki’s  wrapper. Furthermore semantic metadata,  which are embedded in the HTML content of a post, are extracted and relate with the post via a sioc:embeds property. I am not sure if sioc:embeds is the best  property to relate the embedded entities with its container post. Maybe something like sioc:topic would be better. However the URI of the embedded resources are related with the post URI and the parts of the resource description, which has been embedded, are also exposed (because if only parts of a resource’s description are reused or embedded in a post’s content, it might be also interesting for machines to know which parts have been reused/embedded in the posting and if the reused/embedded resource is described via microformats, it might not have an URI which identifies the resource).

I use the ARC2 library (version from 2009-02-12 -> it is important to use this version or higher) which provides a parser to extract different embedded semantic metadata formats such as RDFa, eRDF and MF. I modified the method declaration of the toRDFXML method in the ARC2_Class.php file . Thats why at the moment “my” version of the ARC2_Class.php must be included to the SIOC Exporter arc folder. But Benjamin already told me that the modification will be included in the next ARC2 version.

If you fancy to test this version of the WP SIOC Exporter, download it here.

Any thoughts are of course welcome!

The URL of del.icio.us bookmarking service has changed. Since September 2008 instead of the fancy “name-hack” (del.icio.us) they use something easier to write: delicious.com.

I noticed the new re-design (see Screen Shots And Feature Overview of Delicious 2.0 Preview) but did not pay attention to the URL until someone mentioned it.

Are you using Delicious? Via a website or using some additional software?
