Headlines Plugin

Show headline news in TWiki pages based on RSS and ATOM news feeds from external sites

Description

touch="..." Touch (edit/save) topics if the feed has updates. Specify a comma-space delimited list of TopicNames or Web.TopicNames, such as "%TOPIC%, NewsLetter". Useful to send out newsletter using MailerContrib, showing new feeds since last newsletter. To update feeds, visit topics with feeds in regular intervals (using cron with wget or the like). N/A

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>.

Examples

Traveling abroad for work? In today's interconnected world, many people travel overseas for business. They do so for a number of reasons.

While not quite the same as going on holiday, business travel can be enjoyable. However, you need to make sure you have everything you need for a successful trip.

Here are a few basic tips to follow when you’re traveling abroad for work.

Arrange for Transport and Accommodation

First, it is essential that you have travel and accommodations arranged for all aspects of your trip so that you know exactly where you need to be at all times.

In addition to your flights, this is also likely to include transport to the airport, along with travel to your hotel. It will also be important for you to know how you will get around. For example, will you be renting a car, booking cabs ahead of time, or using public transport?

Obtain Necessary Visas and Permits

Before you go, check whether you will need any visas or permits for the country you are traveling to. This is sometimes the case whether you’re visiting for work or for pleasure.

Visas and permits can take some time to arrange. So check these as soon as possible.

Travel Abroad with the Right Documentation

Following this, you must also make sure that you have the right documentation for a successful trip. A passport is, obviously, a priority.

However, you might also need a document wallet to hold your tickets, booking confirmations, and any work documents you will need. You should also have digital backups.

Obtain Business Travel Insurance

Business travel insurance should also be arranged once you have made bookings. Of course, you hope you will not need it. However, it is better to be safe than sorry. Business travel insurance will cover potentially costly aspects such as flight cancellations, theft, and medical incidents.

Pack Lightly When Traveling Abroad

You will want to pack lightly when traveling abroad. However, you also want to ensure you have everything you need. This can be challenging.

It is important to keep in mind that this is a work trip and not for leisure. Therefore, you should not need a huge amount. But it is a good idea to have comfortable clothing for the times when you are not working.

It is then a matter of having work clothing, gadgets for travel, electronics you need for work and pleasure, and toiletries.

Commercial buildings have the highest energy demands in the market. And they also account for significant wastage. This means exorbitant costs and lower energy efficiency, which eventually damage your bottom line. What to do? Let's take a look.

How to Boost Your Office Building's Energy Efficiency

Many entrepreneurs started 2020 with a lot of targets to achieve and challenges to overcome.

Facing the opportunities of this promising year, many also swore to start fresh and get fit. However, they forgot to keep their buildings fit!

Get Your Building Healthy and Fit

Don't be surprised. Buildings can become fat and lazy, too.

Commercial buildings have the highest energy demands in the market. And they also account for significant wastage. This means exorbitant costs and lower energy efficiency. These eventually damage your bottom line.

Therefore, it's high time we start focusing on the energy health of our buildings.

Fortunately, there are many ways by which you can increase the energy efficiency of your building and save a lot of money in the process. Here are some of them.

Justify How Much You Need

First off, create an action plan documenting how much energy you actually need. Then, instead of reducing energy consumption immediately, eliminate wastage.

Get an energy audit conducted and identify hidden energy leaks. Also measure the air-tightness of the building's structure. Based on the report, rectify problematic areas. For example:

  • Should you invest in an energy-efficient air conditioner, or retrofit the building effectively and eliminate the need for air conditioning at all?
  • How can you save electricity?
  • Have you compared the plans at utility providers in the area or on local energy comparison sites?

Here’s something to think about. Origin energy plans come with the option to offset greenhouse emissions. Plus, they cater to both residential and business customers.

Go Retro for More Energy Efficiency

Retro commission the building to improve the energy efficiency of its equipment and systems. This will help you address problems with the current design and structure of the building. Moreover, it will also help you avoid expensive repairs in the future.

This is because running an uncommissioned building is like driving an old, worn-out car with a fuel cap hanging open. Sounds stupid, doesn't it?

Add Exterior Insulation

Sun-proof the building to reduce its reliance on air conditioning during summer. This is the best way to cut down on energy waste and increase energy efficiency.

For one thing, air conditioning is a significant energy sink. This means it consumes a lot of energy and spikes up your energy bill. To counteract this, add exterior insulation.

Also, consider using solar screens, films, and remote-controlled louvred blinds.

Update or Replace Windows

Windows have transformed in the last two decades. The right windows can help conserve energy and reduce your energy expenses.

By saving heat during winter and losing heat during summer, the right windows can maintain an optimal temperature all year around. So get your current windows replaced with energy-efficient ones.

However, if your windows are in good condition, don't replace them. Just update them. You will still notice a massive change in your building’s total energy consumption.

Below are a few things you need to consider when choosing windows:

  • Operating type
  • Material
  • Frames

Be Responsible and Encourage Others to Be as Well

Numerous studies reveal that human behavior plays a huge role in energy wastage and consumption. Therefore, take charge and be the change.

For example, adopt green methods and promote sustainable business practices. It probably sounds like a broken record, but the importance of reducing energy consumption cannot be overstated.

Use flow meters to measure and monitor the flow of water and gases in your daily operations. Also, try building a green team, and applaud your employees for following green practices.

Educate your staff. One change can change everything.

Energy Efficiency Is Crucial

Energy management is crucial. In fact, we have a global need to save energy. This global need affects energy prices, emission targets, and legislation, all of which provide compelling reasons to start making your building healthy and energy-efficient.
