In this article, I reveal step by step instructions to convert a 10 digit number unix timestamp into a date in Excel. This is particularly useful to Joomla users as Joomla stores and exports date as Unix Timestamps.

Unix timestamp is defined as the total number of seconds since midnight (GMT time) on January 1, 1970 - also known as the Unix epoch.

media queries for common device breakpoints

The @media query is 1/3 of the recipe for responsive design. It is the key ingredient that, in it's simplest form, allows specified CSS to be applied depending on the device and whether it matches the media query criteria.

Greg Corrado a senior research scientist interested in biological neuroscience, artificial intelligence, and scalable machine learning for Google has revealed in a Bloomberg interview (http://www.bloomberg.com/news/articles/2015-10-26/google-turning-its-lucrative-web-search-over-to-ai-machines) a significant new algorithm update deployed on 26/10/2015 named RankBrain. In this article, I will attempt to explain what RankBrain is and the impact it might have on ranking.

Google implemented an update to their Mobile-Friendly ranking algorithm on Monday 2nd November 2015 ("An Update To The Mobile-Friendly Algorithm" by Google Webmasters. Google+. November 2, 2015. https://plus.google.com/+GoogleWebmasters/posts/7qKTxCp2PZx). The update focuses on judging how friendly websites are on mobiles and subsequently drop down or penalise any sites deemed to be be non-mobile friendly in searches performed from mobile devices.

This algorithm change will penalize web pages which, when loading, display a large interstitial advertisement to download an app, hiding a significant section of the page content. Google had already stated that he use of such ads was simply not to mobile-friendly, and that their future update would reflect this. Non-compliant pages and websites are now suffering the impact and consequences of this recent change.

Google recommend that "webmasters use more user-friendly formats such as app install banners". By doing so, they continue by writing "we hope that this change will make it easier for searchers to see the content of the pages they are looking for".

We have seen an impact on some of our sites which do not use Interstitial Ads. This suggest that the algorithm is not just about covering the content but also how mobile-friendly your pages are.

In this article, I write about re-building your K2 image cache. If like me, you try and test various images sizes for your perfect article style and display, you have probably encounter the challence that K2 presents when resizing images. I came across a really useful tool written by Robert Deutz and found at this address: https://github.com/rdeutz/rebuildK2imageCache

The php script will rebuld your entire K2 image cache in just a few seconds saving precious time and frustration. Here is how to implement.

I like to develop my websites in a live environment which saves time when it comes to switching it to the world. It also provides an excellent platform for error checks and live behaviour. In order to be able to develop online and on my servers without having to work on my local host, I create a directory which I name say "dev" and which I exclude from search engine crawling in my robot.text file.

I however came across a challenge with one of my domain which has a 301 redirect. How could I access my newly created folder since when trying to access it I would be redirected. Here is the exception rule and code which allowed me to overcome the challenge:

The above code needs to be added to your .htaccess file. The code permanently redirects with a 301 redirect all traffic to the site to http://www.newdomain.com, except requests to resources in the  /my-folder directories.  The user are redirected to the equivalent of the page they requested by using the (.*) capture group and then including $1 in the new URL.

Sometimes applications, programs or software we install automatically enable themselves within Windows 10 start-up. In other, each time you switch your PC or tablet on, the application, program or software initialise automatically. This can slow down your windows 10 start up process but also it's speed as the apps will continue working in the background using your computer memories and CPU.g

Fortunately, adding or removing an app or program from the star-up list is relatively easy. In this article, I explain how to enable or disable a program from windows 10 start-up processes list.

We have learned that Google is rolling out a series of new search algorithms which target websites that have been victim of hacking or spam.  and could result in fewer search results being shown for certain queries due to hacked results no longer being shown.
