  Battlelog: Modern Web Applications are Here

It's the shooter season of the year and this fall was all about Modern Warfare 3 versus Battlefield 3. And being the kind of game they are they also try to keep their audience playing by introducing some additional level of engagement. Both Call of Duty and Battlefield introduced their own online community websites and statistic platforms. Call of Duty has Elite, Battlefield has Battelog.But just because these services are sitting in the same spot it does not mean they are in any way similar. An...

  How Query Optimizer Works in RDBMS

In a previous post, we discussed how the various relational operators are implemented in relational database systems. If you have read that post, you probably still remember that there are a few alternative implementations for every operator. Thus, how should RDBMS determine which algorithm (or implementation) to use? Obviously, to optimize the performance for any query, RDBMS has to select the correct the algorithm based on the query. It would not be desirable to always use the same algori...

  So you want to write JavaScript for a living?

What do you need to know if you are interviewing for a job that involves Javascript development? What kind of expectations do employers have of candidates now that the state of client side development has been changed with the rise of asynchronous JavaScript and the often slick, supporting interfaces? These were questions I was asking myself after a friend pointed me to an interesting job posting over at Meebo that included some JavaScript puzzlers on logical operators, DOM odditi...

  Speed Hashing

A given hash uniquely represents a file, or any arbitrary collection of data. At least in theory. This is a 128-bit MD5 hash you're looking at above, so it can represent at most 2128 unique items, or 340 trillion trillion trillion. In reality the usable space is substantially less; you can start seeing significant collisions once you've filled half the space, but half of an impossibly large number is still impossibly large. Back in 2005, I wondered about the difference between a checksum and...

  Popular Golang JSON libraries evaluation

JSON (Javascript Object Notation), a prevailing data exchange format, is widely used in various platforms and languages. Golang, of course, will never miss the support for JSON. And with its own standard library, such as those interfaces like the REST API from the API Service in Kubernetes, it can easily process JSON. Although Go’s library works great, we can still seek those open-source JSON libs in Github to maximize our efficiency. Then the features, performance, applicability of these ...

  Static Code Analysis

The most important thing I have done as a programmer in recent years is to aggressively pursue static code analysis.  Even more valuable than the hundreds of serious bugs I have prevented with it is the change in mindset about the way I view software reliability and code quality.It is important to say right up front that quality isn’t everything, and acknowledging it isn’t some sort of moral failing.  Value is what you are trying to produce, and quality is only one a...
