Client-side analytics is broken. The numbers produced by it are trivially spoofable by competitors and nefarious characters.

C++ for the Real-Time Web

C++? Why on Earth? C++ seems like one of the least likely languages to write a web application in. C++ is associated with complexity, both with language design and the need to manually manage memory. Programming in C++ unleashes a whole class of bugs associated with memory corruption and memory allocation. This is a trade off for giving more power to the developer along generally being much faster than equivalent programs in languages such as Python or Ruby. Real-time Web as a Use Case Making...

The task status is usually stored in the database so that it can be easily integrated into a Rails application where asynchronous job execution is desired. Normally when a job fails to execute or error occurs, it would save the error into the database with the column last_error. Ideally all these will be handled b...

It wasnâ€™t until last month that the opportunity to use Scala in a large scale project finally arose and I dove right in. The project was a typical REST based web service built on top of Amazonâ€™s Elastic Beanstalk, SimpleDB, S3 and Redis*. First off letâ€™s talk about why I chose Scala in the first place. After spending a good deal of my las...

On Employers, Portfolios, Commitment, and Cake

You might know from experience that planning for a wedding is no simple feat. In the months leading up to our wedding, my then fiancÃ© and I spent countless hours planning and making sure that no detail was overlooked. Among our top priorities was finding a skilled baker to create a delicious and beautiful cake. On the recommendation of a friend, we considered a baker named Jennifer. We read her "culinary resume." We were impressed by her references and experience, and our initial conve...
