Big Data to Tomcat Behind Nginx

October 5th, 2015 2 comments

In a Web application I created, I need to upload some data to a Java Servlet for further processing. I wish JavaScript could be more powerful so that I can process everything in the front end, but I could not find a good JavaScript library for the job.

Everything works well until some big changes got in – it stopped working sometimes and the pattern is not quite consistent. Initially I thought it was because of long time processing at the server side.

Big Data or Big Junk?

December 8th, 2012 12 comments

Two weeks I got a problem with my blog site. Somehow I could not post to announce the GA of open source ViJava API for vSphere 5.1 there. After searching and researching, I found out that the wp_commentmeta table was filled with extra amount of data that exceeded the per database limit of 100MB imposed by my service provider. While I was enjoying Thanksgiving holiday, some spammers and their robots worked diligently posting thousands of spam comments on my site.

  • The growth is accelerating. By 2020, there will be 50x more data than today.

Will Enterprise Hardware Be Hot Again?

July 23rd, 2012 No comments

BusinessWeek recently published an article “In Silicon Valley, Hardware is Hot Again.” Almost all big names started to sell hardware now, Microsoft, Google, and Apple of course. Apple’s stellar success in iPhone and iPad disrupted the conventional wisdom that software is higher in margin compared to hardware. Also, Apple’s hardware and software combined devices posts a real risk for Microsoft and Google. To be exact, the hardware in the article title should really be software bundled hardware. That is why Google and Microsoft had to get into hardware business competing directly against Apple.

GPU for Big Data Processing

June 27th, 2012 5 comments

While talking about the data processing, we naturally take CPU for granted. However, latest GPU (Graphics Processing Unit, also know as Visual Processing Unit, or VPU) comes with hundreds of cores and calculates much faster than CPU. The question is how practical it is to use GPUs in processing big data.

This past week was a busy one for Hadoop community with two Hadoop events in Silicon Valley. The first one was “what role will hadoop play in the enterprise” by Churchill Club which attracted about 300 attendees in a Palo Alto hotel. The second one was the much bigger conference Hadoop Summit in San Jose Convention Center. I will write a separate article on the second event soon.
