Headlines Plugin

Description

This plugin displays RSS and ATOM feeds from news sites. Use it to build news portals that show headline news.

Note: Syndic8.com ( http://www.syndic8.com/ ) lists many RSS and ATOM feeds.

Syntax Rules

%HEADLINES{"..."}%

The header and format parameters might also use variables rendering the dc, image and content namespace information. Note, that only bits of interest have been implemented so far and those namespaces might not be implemented fully yet.

Rendering the dc namespace

The following variables are extracting the dc namespace info, that could be used in header and format. Note that some of the variables are already used above. This is done by purpose to use different feeds with the same formatting parameters. If there's a conflict the non-dc tags have higher precedence, i.e. a <title> content </title> is preferred over <dc:title> content </dc:title>.

• $title: channel/article title (dc:title)
• $creator: channel creator (dc:creator)
• $subject: subject text; this will also add an image according to the subject hash list, see above (dc:subject)
• $description: ... (dc:description)
• $publisher: the channel/article publisher (dc:publisher)
• $contributor: ... (dc:contributor)
• $date: ... (dc:date)
• $type: ... (dc:type)
• $format: ... (dc:format)
• $identifier: ... (dc:identifier)
• $source: ... (dc:source)
• $language: ... (dc:language)
• $relation: ... (dc:relation)
• $coverage: ... (dc: coverage)
• $rights: ... (dc: rights)

Rendering the image namespace

An image:item is converted into an <img> tag using the following mappings:

• src: image url (rdf:about attribute of the image.item tag)
• alt: image title (title)
• width: image width (image:width)
• height: image height image:height)

Rendering the content namespace

The variable $content is referring to the <content:encoding> content </content:encoding>.

New Trend: Stand-Up Meetings

Sat, 04 Feb 2012 01:34:15 +0000 Dane Carlson

WSJ:

Atomic Object, a Grand Rapids, Mich., software-development firm, holds company meetings first thing in the morning. Employees follow strict rules: Attendance is mandatory, nonwork chitchat is kept to a minimum and, above all, everyone has to stand up.

Stand-up meetings are part of a fast-moving tech culture in which sitting has become synonymous with sloth. The object is to eliminate long-winded confabs where participants pontificate, play Angry Birds on their cellphones or tune out.

Watch Out For Fake Facebook Stock

Fri, 03 Feb 2012 22:33:56 +0000 Dane Carlson

If you do construction work on someone’s home and they offer to pay you in Facebook stock — before the IPO — it might not be a good idea to accept it in lieu of cash, as one Wisconsin man learned last week.

Marianne Oleson, 46, made her initial appearance in Winnebago County court Wednesday afternoon. Oleson, who is also known to go by the last names of Jansen, Milock or Maloney, is charged with 31 felony counts relating to theft and forgery for the sale of fake stock for the social media company Facebook.

“I was scammed,” said Randy Stafford. Stafford, a construction worker, did work on Oleson’s home in Nekimi in Winnebago County.

According to the criminal complaint, after Oleson couldn’t pay up, she offered to pay Stafford in fake stock in Facebook.

“I think it’s a great opportunity, it’s a growing business so on and so forth,” said Stafford.
