The history of open source has already been written and rewritten a couple of times, so there’s no need to go back to Genesis chapter one and revisit Linus Torvalds’ “just a hobby, won't be big” comments too often. But open source became more than the sum of its parts and the hobbyist...
Big Data is bandied around so much that it seems to have lost what little meaning it had in the first place. What's so special about it, anyway? Some people think it's just a lot of data, more than most companies are used to (Google doesn't count). The real definition isn't much more …...
In the last two years, the Apache Hadoop software library has emerged as a veritable Swiss Army knife of data management and analytical infrastructure. The Hadoop toolset has been positioned as a universal platform for all types of commercial and organizational analytical needs. Hadoo...
Traditional database is difficult to implement real-time application when the data volume is big. Now with data computing middleware, performance of database is improved and real-time application is also realized. The Big Data Real-time Application is a scenario to return the computat...
So I opened my resume and counted how many places I have been since leaving the electronic engineering field. I have had 18 gigs. Most of that time was spent as a consultant in the role of software architect or software process engineer. Most gigs were like building a house. You do the...
With a slight chill in the air, we know Halloween is just around the corner. But what could be spookier than ghosts, goblins or a haunted house? For many IT managers it’s the fear of Big Data, which can be understandably overwhelming at first. We’ve compiled five of the spookiest misco...
When the cloud first came out, there were the usual skeptics. "Why would I need a virtual storage when I have my computer right here?" they would ask. Truth be told, if you can access your stored data by just opening a folder or plugging in a USB drive, why go through the toll of going...
Introducing TraceView's latest support for Solr Server, which provides breakdown of each operation, enabling more precise performance monitoring and troubleshooting. Solr Server provides JMX statistics that show performance details such as query speed and cache hit/miss rates in a mac...
It’s hard to implement an effective, scalable search system, which is why Apache Solr is probably the most popular ‘black box’ in web app infrastructure. Your site is indexed on Google, but that doesn't mean you're done with search. Content-rich websites provide native search functio...
When talking about Big Data, most people talk about numbers: speed of processing and how many terabytes and petabytes the platform can handle. But deriving deep insights with the potential to change business growth trajectories relies not just on quantities, processing power and speed,...
Sentiment analytics is an emerging technology enabler for enterprises to extract the sentiments, opinions and emotions from their Big Data sources, so that enterprises can predict the potential acceptance of their products and offerings. This goes a long way in defining the success of ...
Don’t correct me if you’ve heard this one before: Information wants to be free. The Internet, cloud services plus mobile devices offer limitless possibilities to experience this freedom. With Big Data, information wants to be relevant, too. There are now more mobile phones in the world...
In part 1 of this article, we covered writing web app load tests using multi–mechanize. This post picks up where the other left off and will discuss how to gather interesting and actionable performance data from a load-test. The big problem we had after writing load tests was that tim...
The incorporation of Symfony components into Drupal 8 prompted me to take another look at what I’d lumped into ‘yet another PHP MVC framework’. It quickly became clear that I’d horribly misjudged Symfony. Drupal 8 hasn’t quite hit code freeze yet, but the adoption of Symfony has alread...

Over the past two decades relational databases have been most successful in serving large scale OLTP and OLAP applications across enterprises. However, in the past couple of years with the advent of Big Data processing, especially processing unstructured data coupled with the need for ...
BigData (and Hadoop) are buzzword and growth areas of computing; this article will distill the concepts into easy-to-understand terms. As the name implies, BigData is literally "big data" or "lots of data" that needs to be processed. Lets take a simple example: the city council of San...
Adding more memory to your JVMs (Java Virtual Machines) might be a temporary solution to fixing memory leaks in Java applications, but it for sure won’t fix the root cause of the issue. Instead of crashing once per day it may just crash every other day. “Preventive” restarts are also j...
Over the last couple of months I have been talking to more and more customers who are either bringing their Hadoop clusters into production or have already done so and are now getting serious about operations. This leads to some interesting discussions about how to monitor Hadoop prope...
Hibernate is one of the most used ORM Java frameworks out there. It is really simple to use, just add few annotations and you’re ready to go. However, it is also really easy to experience strange behaviors and bugs if you don’t respect Hibernate’s best practices. That’s why at Tocea we...
Last week, I presented Caching Up and Down the Stack at the Boston Web Performance meetup. It was great to get the chance to present to the 60+ people who came out for the talk. Unsurprisingly, many of the people there knew a lot about caching in all of the different levels I touched o...
If you’re not convinced the hype around Big Data is entirely justified, consider the following statistics: in the time it takes an average person to read this article, 72 petabytes of data (that’s 72 x 1015 if you’re counting) will have been added to the global information pool. Each h...

The good news about the Big Data market is that we generally all agree on the definition of Big Data, which has come to be known as data that has volume, velocity and variety where businesses need to collect, store, manage and analyze in order to derive business value or otherwise know...
Load testing, perhaps more than any other form of testing, is one of those activities that you either choose to do well or risk a result that leaves you worse off than not doing it at all. Half-hearted attempts at load testing yield “results,” but too often those results are inaccurate...
Component-oriented development has many architectural advantages. In spite of this, many developers tend to solve problems the monolithic way on the first go. This article demonstrates how a monolithic design can be modified to achieve component-based design. During this conversion pro...
I was programming in C++ for a living when I fell in love with Java. It was an unintended affair. At the time, I was following a trend with the limited language of C++, which didn’t even have operator overloading or templates, but boasted simplicity and the ability to write the code o...
