Headlines Plugin

Description

- $link: news item link (item.link)
- $description: news item description (item.description)
- $date: the publication date (item.pubDate, item.date)
- $category: the article category (item.category)
Global FORMAT 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>.

Each month, Bitxbox subscribers receive a new coding product for kids ages 6-12. Each box also contains an activity book with over 12 apps to build and app trading cards with lines of code on the back.

Compose Yourself ($14.99)

Any child can compose his/her own music with this revolutionary musical cards and website combo. Each of the 60 cards contain the musical notation for a musical riff. Kids arrange the cards in any order and then enter the card codes into the website to hear their composition played by a full symphony orchestra. By flipping and rotating the cards, kids can create over 200 million possible combinations. For ages 6 and up.

Meccanoid GS15KS (399.95)

The Meccanoid from Spin Master is a robot that measures about 4 feet tall and can be programmed to move in a specific sequence of steps. Featuring Learned Intelligent Movement, the robot learns how to move by watching a human or by being moved by a human.

Funded by Mark Cuban after an appearance on Shark Tank, Roominate is a startup that makes building systems for girls that included circuits (to make things move), modular pieces and universal joints. Roominate rPower is an add-on Bluetooth hub that allows girls to program the building sets’ electronics by using the phone or tablet.

Are you trying to make it as an entrepreneur? Is it turning out to be a bit more difficult than you thought? If so, that's probably a sign you're on the right path. Being an entrepreneur has never been easy. However, with the following tools, you'll probably find yourself making more progress in the near future.

Audible

There are so many books out there on entrepreneurship that you owe it to yourself to constantly keep tapping these assets for advice. Audible is a great way to do it. Depending on the package you go with, you'll pay as little as $15 a month for audio books. This alone is a good deal, but the subscription service means that you'll keep getting prompted every month to continue your education. Whether it's a book on business management, the bio of a successful businessperson or a manual for something like WordPress, there's so much for an entrepreneur to learn and Audible makes it simple.

Dropbox

When working with others, it goes without saying that you'll need to be sharing documents fairly regularly, maybe even every day. You could have employees, customers, business partners, suppliers, developers or any of a number of other people you need to send documents to. Doing so over email is outdated. It's just too inconvenient and even risky to do as an entrepreneur.

Instead, use Dropbox as a central location to keep documents on the cloud, so you can access them from anywhere. Dropbox allows you to give permission to users before they can access specific documents and also makes it possible for them to save changes they make.

Mailchimp

If your entrepreneurial venture involves emailing a large number of people all at once, you're going to want Mailchimp on your side. This platform is a staple in the toolbox of many entrepreneurs and for good reason. Over eight million use it to send some 600 million messages every day. Leverage subscription services, customer profiles, automation, personalization tools and far more.

WordPress

Every entrepreneur needs a website for their business. There are more resources than ever before for building such a site, too. You may go out and hire a developer to do so, for example. However, this could give you a lot of unnecessary overhead early on.

Instead, take a week or two to learn how WordPress works. This user-friendly platform has been the centerpiece of millions of websites all over the world. From blogs to major corporation sites, WordPress has proven it's the best for building websites.

Google Analytics

Once your website is up and running, you're going to need a way to learn who is visiting it, aside from just looking at your actual customers. You also want to know who is showing up, but not buying. After all, how else will you change that? Google Analytics remains the most powerful tool for gaining information about your market so you can grow your customer base.

Many of the world's most successful entrepreneurs are really environmentalists at heart. Their passion to help save the planet provides oftentimes overrides their motivation for personal success. Here is one such story:

RELATED: THE SHOE THAT GROWS IS MAKING A DIFFERENCE

The concern over the waste of plastic water bottles has never been greater. In the U.S. alone, an estimated 50 billion plastic bottles are dumped in landfill sites each year and over 200 billion globally.

In 2010, Sarah Kauss knew in her heart she needed to help do something about it. Inspired by a metal water bottle she'd been carrying around - functional but not at all stylish, especially for young executives - she invested $30,000 of her own money to launch S'Well. Her goal? To rid the world of plastic bottles.

S'Well produces a line of insulated, reusable, BPA-free stainless steel bottles that are designed to keep drinks cold for 24 hours and hot for 12 hours. In 2011, after a plug from Oprah Winfrey and other media outlets, S'Well's popularity soared.

Today, S’well bottles come in 90 colors and three sizes, priced between $25 and $45. The bottles sell in major stores nationwide, including Nordstrom, Neiman Marcus, Starbucks and J.Crew.

Since its launch, the New York-based firm has sold four million bottles. While profitable in its first year, revenue has further surged - to 400 percent between 2013 and 2014 - hitting $10 million last year.

In 2014, Kauss was also named to Fortune's ''40 Under 40'' list.

At S'Well, Founder and CEO Kauss also emphasizes giving back to those in need. The company partners with other charities working towards bettering the environment and communities around the world.
