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/ ) is a good site listing many RSS feeds.

Global HEADER setting
href="..." (Alternative to above) N/A
limit="12" Maximum number of items shown Global LIMIT setting
refresh="60" Refresh rate in minutes for caching feed; "0" for no caching Global REFRESH setting

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>.

Google revealed on Monday it will soon start ''experimenting'' with wireless services and the ways we use them-and that's no small thing. Such Google experiments have a way of morphing into something far bigger, particularly when they involve tinkering with the infrastructure that drives the internet.

As time goes on, the company may expand the scope of its ambitions as a wireless carrier, much as it had done with its super-high-speed landline internet service, Google Fiber. But the larger point is that Google's experiments-if you can call them that-will help push the rest of the market in the same direction. The market is already moving this way thanks to other notable tech names, including mobile carrier T-Mobile, mobile chipmaker Qualcomm, and serial Silicon Valley inventor Steve Perlman, who recently unveiled a faster breed of wireless network known as pCell.

At the moment, Google says, it hopes to provide ways for phones to more easily move between cellular networks and WiFi connections, perhaps even juggling calls between the two. Others, such as T-Mobile and Qualcomm, are working on much the same. But with the leverage of its Android mobile operating system and general internet clout, Google can push things even further. Eventually, the company may even drive the market towards new kinds of wireless networks altogether, networks that provide connections when you don't have cellular or WiFi-or that significantly boost the speed of your cellular connection, as Perlman hopes to do.

There’s a plethora of businesses in the marketplace which provide the same goods and services as you but it’s your job as the leader of your company to use every tool available to make your company stand out above all of the others. Customers are searching for professional companies committed to excellence and by using effective marketing tools that include printed materials you can outperform your competition hands down. Printing companies stand ready to help you bring your marketing ideas to life and finding the right one for your individual needs will be your first step towards establish your brand. Let’s take a look at how to use effective marketing to establish your company’s brand and make your organisation a household name.

  • The first point to consider is having your marketing materials all created by the same team. Using a professional printer such as www.eazy-print.com can help you to create a flow in your strategy that is carried with each piece of printed material that you use. Your literature will have the same look and will demonstrate that you pay attention to details; using professional-looking marketing materials also sends the message that you are serious about your company and stand ready to help your customers in any way possible. 
  • Keep the ideas that you share with your printer simple but informative and credible. Ask the printer to use white space whenever he deems it necessary; this can effectively frame your content and add power to its appearance.  
  • As you choose your logo or other images that will be used in your business materials, make sure that they are of good quality, that you like them, and that they truly represent your company. This decision is one that will remain with you for a number of years and will establish your brand in the corporate community. 
  • When your business grows and is ready for expansion, you may want to attend trade shows and conventions to further your company’s progress. Ask your printer if he can provide sturdy display stands and personalised banners to use in your booth; you can purchase PVC banners that can be used again and again which is an excellent investment for your business. Networking at corporate gatherings can do a great deal to grow your company and establish your exceptional goods and services that are being offered to your clients. 
  • Include brochures, flyers, and some specialised materials in your marketing order; these will place valuable information about your company directly in the hands of your potential clients and show them that you are interested in helping them find a solution for their problems. Keep in mind that effective marketing includes a multi-layer of tools used to convert your contacts to sales quickly and efficiently. 

For your company to be a success, people in your community need to know information about your company and the products that you offer to them. Using print materials can be one of the most effective strategies that makes your company outperform your competitors.

On opening day - Memorial Day weekend, 2011 - Garcia and Swan mugged for the cameras holding giant sundaes, grins plastered across their faces.

There was good reason to smile. For some weeks after its opening, the restaurant had hourlong waits for tables. As Judith Beermann wrote on the Georgetown Dish website, guests ''enjoyed lunch as if they've been coming here for years.''

Away from the gaze of guests, however, it was a different story. The partners began to ''butt heads'' almost immediately after signing their lease, Garcia later told police. One of their earliest problems centered on something both basic and critical: negotiating how the company would be set up and operated.

Swan wanted to head up the day-to-day operations, overseeing staffing, purchasing, and service. He saw Garcia focusing on PR, marketing, and private events: acting as the public face of Serendipity. ''[I have] opened numerous hospitality locations and [have] a good reputation,'' Swan e-mailed an attorney at the time. ''This restaurant and investment opportunity needs ONE person with the final say-so.''

Garcia didn't like that idea-and didn't think running Rhino Bar qualified Swan for the task. ''It's not rocket science to own and run that,'' Garcia later told police. ''He's not sophisticated enough to be a restaurateur. Between a college bar and a restaurant, it's night and day.''

After months of haggling, Swan and Garcia finally signed the paperwork establishing their partnership. Swan did so thinking he was in charge. Only later did he realize that wasn't the case. Edited into the final draft was a change he hadn't noticed at the time: It gave the partners equal authority over day-to-day operations at Serendipity. The arrangement meant future disagreements would be a nightmare to settle. If irreconcilable problems arose, Swan and Garcia would have no choice but to appeal to Serendipity's investors. And the final interest structure-42.5 percent for Swan, 32.5 percent for Garcia, 10 percent for Garcia's mother, 5 percent for Garcia's brother, and the remaining 10 percent split between a friend of Garcia's and an acquaintance of Swan's-would create an environment where investors had to pick sides.

The agreement also made it nearly impossible for either Garcia or Swan to force the other out. ''In the event of any serious disagreements . . . termination of a manager was very difficult,'' Garcia said in an affidavit. ''It would be messy to split up the business.''

There was one way, however. Tucked inside the 25-page document was a brief clause that would become pivotal in the future: It stated that if convicted of a felony, a partner could be removed from the company.
