 Back in the misty eons of time, it used to be easy to measure the performance of your application. You’d grab a stopwatch, load up your web application, and see what happend. If it was slow, you’d look at the mess of PHP, HTML and CSS you crammed into index.php and make sure that you w...May. 5, 2013 03:00 PM EDT Reads: 1,043 |
 A question that every online application provider will face eventually is: Does my application scale? Can I add an extra 100 users and still ensure the same user experience? If the application architecture is properly designed the easiest way is to put an additional server behind the l...May. 5, 2013 10:00 AM EDT Reads: 1,507 |

 When you look at the database market, it’s a virtual jungle out there. Those of us in the industry 15 years ago can look back and remember when we only had the option to use a relational database from Sybase, Oracle, Microsoft or IBM. That was pretty much it if you were planning to bui...May. 2, 2013 09:45 AM EDT Reads: 1,759 |
 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.

 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...Apr. 26, 2013 10:00 AM EDT Reads: 1,326 |
 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.

 The easiest way to make your code run faster is to do less. At some point, though, you don’t want to do less. Maybe you want to do more, without it being any slower. Maybe you want to make what you have fast, without cutting out any of the work. What then? In this enlightened age, the ...Apr. 23, 2013 10:00 AM EDT Reads: 1,279 |
 I started in the web performance industry – well before Application Performance Management (APM) existed – during a time when external, single page measurement ruled the land. In an ecosystem where no other solutions existed, it was the top of the data chain to support the rapidly evol...Apr. 22, 2013 09:00 AM EDT Reads: 1,668 |
 Abstractness is a measure of the rigidity of a software system. Higher the abstraction, lower the rigidity (or greater the flexibility) and vice versa. And the stability is a measure of tolerance to change as in how well the software system allows changes to it without breaking it. Thi...Apr. 18, 2013 11:45 AM EDT Reads: 1,491 |
 We have been blogging about the same problems and problem patterns we see while working with our customers over the past few of years.

 Social media applications like Facebook walls, Linked-in dashboards and Twitter tweet-boards have inadvertently opened up a new paradigm of pushing data/information to the users.

 The concept of "Just-in-Time" was pioneered in the manufacturing supply chain as a critical way to reduce costs by minimizing inventory. Implementing a just-in-time system that can handle unexpected demand is not a trivial undertaking. It requires the confluence of a number of discipli...Apr. 4, 2013 12:15 PM EDT Reads: 1,668 |
 A/B and multivariate testing are often used to improve the conversion funnel. What these tools do is randomly place alternative change images, text or other design elements to gather statistics about how these things affect site visitors.

 As much as we try to avoid performance problems, they do happen. It is inevitable. But it is possible to learn to react fast, and in some occasions fast enough that the impact on the end users is negligible. Despite operators’ best efforts, 73% of performance issues are reported by use...Mar. 29, 2013 08:00 AM EDT Reads: 1,759 |
 Both Paramount and Universal celebrated their 100th anniversary last year, which is a long time to be in the movie business. Arguably, both have made some good, some great, and some bad movies.

 I love movies. There is just something about them that can teach us a lot about life. One of my favorites is “Groundhog Day.” The construct of this movie is that the main character Phil, played by Bill Murray, is trapped having to live the same day over and over again.
