SQL to Hadoop

"More organizations, small and large, are interested in moving their data from SQL relational databases to an Apache Hadoop back end. Although SQL is always a solid option in many cases, Hadoop has advantages in data processing that are battle-tested by several major web properties. These days it seems that Hadoop is the best game in town for "Big Data" handling. For users that want to either experiment with Hadoop or put it into production-use, there are a couple of tools available for migrating SQL data to Hadoop. They include: Cloudera's Sqoop, cascading.jdbc, and cascading-dbmigrate." - see details here

Mobile service 'Car parking place' via our mashup Mobile map. This service lets you save your parking place right on the map and find it later easily. Screenshots, step by step:

4. You can even click on the marker for saved location and draw a route to it (for walk or drive):

With this app you can browse recent links posted in Twitter’s timeline." - our mashup Links in Twitter on MakeUseOf site.

Sweet HTML5 future: record audio files right in browser. Flash caput?

How to share your location

Our GeoPost mashup has been updated. Idea is very simple. Many modern blog platforms (most of them actually) let you publish data by email. You can just send email to some service address and platform transforms it into a new post. For example, in Posterous you can send data to, in Friendfeed it is, in Blogger you can set address in Settings->Email&Mobile tab etc.

And our mashup Geo posts lets you create a personalized mobile web application for posting geo related data to your blog. Just set a service email address in the form below and get a link to mobile web application for iPhone, Android or S60 platform. This web application lets you email new postings right from the map - just click on the draggable marker that presents your location. And application automatically adds to email a link to the location. So your posts will have a direct link to some map. It is probably the easiest way for sharing locations, write about some check-ins, lets your readers to see the place you are writing about etc.

Also you can create with this mashup your own emergency communication tool. You can predefine not only email address for sending your location but a phone number for SMS too. So you will be able to share your location via email/sms just in one click.

Mashup creates a personal link for your geo-sharing application as well as QR code for loading this link right into your mobile.

For gmail users mashup supports Google Buzz posting too.

Wire framing

"A wireframe in essence, is a visual representation, guide, and basic element structure of a websites interface design. Wireframes are usually the product of an idea that’s later reproduced on paper (or screen) so that they can preserve and maintain the consistency of visual similarities throughout a websites design. Not only that, but wireframing allows us to save valuable time and money. Deciding to create a website without planning, many times results in a very poorly functional interface. This will ultimately drive users away from your website, and tarnish the quality of your brand." - a very useful collection of prototyping services.

Getting Real about NoSQL

"The ACID RDBMS isn’t appropriate for every need, nor is the NoSQL solution.
A social media site is not an inventory system. A banking account management system is not a social news aggregator." - from here. More than reasonable remarks about NoSQL buzz.

Mobilize your content

Our mashup QR code maker has been updated. Just type (and/or copy/paste) any text, maybe with some links inside, and get two things:

a) mobile web page for this content
b) QR code for loading this page right into your phone (mobile browser)

What is else? You can share this mobile page with your friend right from the mobile (email, sms). You can add files to your page, so they will become downloadable right from that page. Actually you can even use this tool just for sharing your files.

During the mobile page generation mashup automatically proceeds links in the text. You can even add mobile transcoding to the links make content available via mobiles.

Another interesting option is one time readable pages. You can create a page (or downloadable content) that will be destroyed after the first reading. So this option could be used for premium content for example.

How to server static content

From a performance perspective, the trouble with cookies is that once the server sets a cookie for a particular domain, all subsequent HTTP requests for that domain must include the cookie. Even if the server has no use for the cookie, as is usually the case with static components, the cookie is sent over the wire anyway, bloating our request headers with useless code.

So serving static content (e.g. images, css etc.) from a cookieless domain is a standard performance best practice. See more details here.

And JSOS provides several components lets you share your content across several servers. See for example: Load balance and Moved permanently servlets.
