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 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. Nnote, that some of the variables are already used above. This is done by purpose to use different feeds with the same formating parameters. If there's a conflict the non-dc tags have higher precedence, i.e. a <title> content </title> is prefered 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 refering to the <content:encoding> content </content:encoding>.

Inventor Stirs Up Kitchen Gadget Market

MarketWatch:

A project that began in response to a lumpy bowl of Malt-O-Meal is now, after nearly a decade of tinkering in his spare time, ready to hit the market.

“I wanted to find a way to make a better bowl of Malt-O-Meal in the microwave,” said Wylie. “I saw the potential of using the turntable as a source of motion very early. But it took quite a few attempts and designs to get it all working perfectly.”

The real breakthrough in development came with the addition of his patent-pending anchor bar, which maintains a consistent downward pressure on the entire assembly, holding it securely in place.

Wylie wants to use his invention to create jobs in Kansas, particularly in the Wellington area. He plans to use the money raised from the sale of the StirMate to fund research and development for future products and develop as many Kansas ideas and innovations as he can.

“The StirMate has been well received by many people who want to send the production to China,” said Wylie. “But my goal is to create jobs locally and help the Wellington economy.”

Best Banks For Small Biz Loans

The Huffington Post:

When it comes to getting a loan for your small business, it may not come down to who you know, but where you go. Banking Grades, a new grading tool from Philadelphia-based MultiFunding, found that some of the nation’s biggest banks have the worst performances when it comes to small-business lending. Meanwhile, banks that recorded the best small-business lending performances are the ones most entrepreneurs have probably never heard of.

The big banks (defined as those with deposits of more than $10 billion) that ranked the highest for small-business lending are:

1. Zions First National Bank, Salt Lake City. Grade: A (25.44 percent)
2. First-Citizens Bank & Trust Company, Raleigh, N.C. Grade: B (23.8 percent)
3. Synovus Bank, Columbus, Ga. Grade: B (19.25 percent)
4. Chase Bank Usa, National Association, Newark, Del. Grade: B (18.34 percent)
5. Bancorpsouth Bank, Tupelo, Ms. Grade: B (17.13 percent)
6. Wells Fargo Bank Northwest, National Association, Ogden, Utah. Grade: B (13.71 percent)
7. Arvest Bank, Fayetteville, Ark. Grade: B (12.82 percent)
8. Whitney Bank, New Orleans, La. Grade: B (12.02 percent)
9. Capital One Bank (Usa), Glen Allen, Va. Grade: B (11.85 percent)
10. Tcf National Bank, Sioux Falls, S.D. Grade: B (11.49 percent)
