Revisit-After meta tag

Once in a while I’ve seen this tag in the HTML source of older websites, I too had implemented it at one time, but forgot the reason. Here’s what I’ve turned up, and as such have removed it universally.

This tag was at one time used by one small search engine in Vancouver Canada, it was never picked up by the larger search organizations and as such has very little relevance.

<meta name=”revisit-after” content=”7 days” />



OpenSearch is a relatively obscure topic that I’ve only crossed a few times, here is the premise.

A simple tag can be added to your content, in this case HTML, but a feed can also contain this element.

<link rel="search" href="" type="application/opensearchdescription+xml" title="" />

That link refers to a file that resembles the one below, in it you can specify the URL to the search facilities on a website, or as in the case below, use the parameters for a Google search of your website.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE OpenSearchDescription>
<OpenSearchDescription xmlns="" xmlns:moz="">
<Description>Use Google to search our web site.</Description>
<Tags>giantgeek skotfred</Tags>
<Contact>[email protected]</Contact>
<Image width="16" height="16" type="image/x-icon"></Image>
<!-- NOTE: this uses Google, you can give your own search url instead -->
<Url type="text/html" method="GET" template=" {searchTerms}"/>
<Url type="application/opensearchdescription+xml" rel="self" template=""/>

Many modern browsers that provide a ‘search box’ in the browser interface, can then add the capability to perform a search of your website even when the user is not there already.

Apple IOS 6 Smart App Banners

If you have made an investment in creating a device specific application in addition to a traditional web application, there is also a good chance that you want to drive your users (customers) to use the native application.

With the release of Apple IOS 6 in September 2012, this ability was made possible with the use of a simple HTML <meta> tag on your web page. You will need to replace the x’s with your app-id from the Apple Store.

<meta name="apple-itunes-app" content="app-id=xxxxxxxxxx" />


Install Opera Browser on Ubuntu

I was recently attempting to port some older Selenium tests to a new Linux machine and found that I did not have the Opera browser installed. Thus, I submit the following.

There are several ways to go about doing this, depending upon your skills.

1. Most simple IMHO…

  • Add the path to the application file, then install, updates will come as they are released.
    sudo vi /etc/apt/sources.list
  • Add the following line to the file.
    deb stable non-free
  • Update the software registry:
    sudo apt-get update
  • Install:
    sudo apt-get install opera

2. Another method, with the same results:

  • sudo sh -c ‘echo “deb stable non-free” >> /etc/apt/sources.list.d/opera.list’
  • sudo sh -c ‘wget -O – | apt-key add -’
  • sudo apt-get update
  • sudo apt-get install opera

3. Additionally, you can simply download the files from the Opera website and uncompress wherever desired on your drive.
