Web administrators transitioning the existing WordPress sites (and image resources) to Amazon S3 have couple of paid plugins to choose from to ease the move to S3. However, most of the WordPress plugins come at a pretty hefty prices, some as high as couple of hundred dollars. The following guide outlines the step by step option that is completely free of charge. [Read more…]
This article is just me thinking loud about creating something better than the simple wordcount.java example that is usually bundled with the Big Data solutions such as Hadoop – which I covered in the previous post. I wanted a script that would be a bit more complex and relate more to a meaningful web indexing. I wrote a Java program that acts as a Web Parser and can programmatically provide the meaning of any website by statistically judging its content. If ran against Google search results, it can also provide AI like answers to complex questions (such as ‘who is the president of some country’), or guess the closest meaning behind the set of keywords (such as ‘gold, color, breed’ will result in the response: ‘Golden Retriever) – see the examples below. Of course, this is just a result of a bit of a spare time. But it’s something that could perhaps be further explored, as a method to derive basic meaning behind the textual content in big data (to get the gist of the content in couple words). Anyhow, in the current form it’s just a further play on Hadoop’s wordcount.java.
In this article I’ll outline my position on AJAX application model and try to provide an answer the following questions:
- Is AJAX just another fad, or will it continue to promote the development of Web-based software?
- Can an application model ever actually be taken seriously when it does not normally allow information storage on the local client or when certain users prefer working in an offline mode?
I’ll also explain whether I think that AJAX will continue to encourage the development of Web-based software or if we should use other technologies instead.
This article is the eighth post in the series that introduces HTML5 to beginners. We’ll design a simple HTML page, that will use AJAX to get a UTC date and time and some other details from a PHP file that will act as a server-side script. [Read more…]

This is a fourth article in the series dedicated to HTML5 programming for beginners. In this post, we’ll create a fictitious website project dedicated to two existing courses at University of Liverpool. Page will list a a description of two modules that are part of the studies at the University of Liverpool, in MSc in Web Sciences and Big Data program: https://www.online.liverpool.ac.uk/programmes/msc-in-web-sciences-and-big-data/structure [Read more…]
This is a third article in the series dedicated to beginners in HTML5 programming. In this example, we’ll create a file called simpleTablewithCSS.html, in which we’ll show a table that has 2 rows and 2 columns (each cell 200px x 200x), with styling done by utilizing CSS. The background colors top to bottom in this order: red, yellow, blue and teal. [Read more…]

I was asked us to create a post in which we explain our position on the value of HTML5 frames. As far as my position on this topic, the question is not formulated correctly. Any discussion about HTML5 frames, should be dismissed, as the frames in their original HTML 4.01 form are no longer supported in HTML5. And in addition to above statement, possibly also, because no similar concepts were introduced in HTML5 to replace the original 4.01 functionality. [Read more…]
