  Cache them if you can

“The fastest HTTP request is the one not made.” I always smile when I hear a web performance speaker say this. I forget who said it first, but I’ve heard it numerous times at conferences and meetups over the past few years. It’s true! Caching is critical for making web pages faster. I’ve written extensively about caching: Call to improve browser caching(lack of) Caching for iPhone Home Screen AppsRedirect caching deep diveMobile cache file sizesImproving app ...

  How to hire an idiot

Wow, I remember how idealistic I was when I was about to bring on my first employee! After dealing with bad bosses over my career, after doing a whole lot of thinking about how I was going to be a great boss, and after doing a whole lot of reading about how to hire effective people, I was really looking forward to it. I was going to:-- Hire people smarter than myself, who get things done!-- Trust them to do their job, let them do their job and give them enough resources to do it!-- Pay them WELL...

  Data Scientists and Their Harder Skills than Big Data

The field of data science is often confused with that of big data. Data science is an aid to decision makers in a company with a logical approach.  Who is a Data Scientist?  A Data Scientist reviews a huge collection of data(that may extend to a couple of terabytes of disk space or thousands of excel sheets). This humongous chunk of data is not feasible for being handled, sorted and analyzed by a single person. Here we require the help of data science, and most recently, the field of A...

  Dart is to JavaScript as C# is to C++

Given the background of Lars Bak, the Google engineer whose V8 JavaScript interpreter upended Firefox's claim on speed, it was reasonable to suspect Google's new Web development language might look a lot like Smalltalk. But that might have taken the Web in a strange and different direction. Today, on the day of a Web developers' conference in Denmark, Google and members of the Chromium open source development team raised the curtain on Dart, the company's bid for a new and somewhat more str...

  Three Simple Ways to Improve the Security of Your Web App

It seems like web app security has entered the public conscious recently, probably as a result of the press covering the activities of groups like Anonymous and incidents like security breaches at several CAs. Here are a couple of quick security tips to improve the security of your web apps. Think of these as low-hanging fruit, not as a substitute for thorough analysis of your app’s security. If there’s interest in this topic we can do more posts, too - let us know in the com...

  What Can We Learn From Dennis Ritchie?

As we noted earlier this week, one of the founding fathers of UNIX and the creator of C, Dennis Ritchie, passed away last weekend. While I feel that many in computer science and related fields knew of Ritchie’s importance to the growth and development of, well, everything to do with computing, I think it’s valuable to look back at his accomplishments and place him high in the CS pantheon already populated by Lovelace, Turing, and (although this crowing will be controversial, at lea...

  A plugin to update last_error in Delayed Job

delayed_job is a process based asynchronous task processing gem which can be ran at background. It will fork the specified number of processes to execute the tasks asynchronously. 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...

  The Giant Mafia

There is an old Chinese saying "Things of a kind come together. People of a mind fall into the same group.". In the wave of Web 2.0, there are many emerging IT giants coming out the world. And many of them are founded by a group of people who previously worked together at the same company such as PayPal and Facebook. This is called giant mafia. Let's see what people from the big IT giant have done after leaving the original company. The PayPal mafia Peter Thiel, co-founder and CEO of PayPal bef...

  Write Your Own R Packages

Introduction A set of user-defined functions (UDF) or utility functions are helpful to simplify our code and avoid repeating the same typing for daily analysis work. Previously, I saved all my R functions to a single R file. Whenever I want to use them, I can simply source the R file to import all functions. This is a simple but not perfect approach, especially when I want to check the documentation of certain functions. It was quite annoying that you can’t just type ?func&n...
