  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...

  Bionic Office

Well. That took rather longer than expected. We have, finally, moved, into the new Fog Creek office at 535 8th Avenue, officially ten months after I started pounding the pavement looking for a replacement for my grandmother's old brownstone where we spent our first few years, working from bedrooms and the garden. Most software managers know what good office space would be like, and they know they don't have it, and can't have it. Office space seems to be the one thing that nobody can get rig...

  Want to write some code? Get away from your computer!

I’ve recently realised something. The best place to write code isn’t in front of your computer, with your compiler, IDE and tools. The best place to write code is far, far away from any of these tools – somewhere where you can think properly. For a language with which you are fairly familiar, the mechanics of translating the program in your mind to a program that the compiler can compile (or the interpreter can interpret) is fairly easy – it’s coming ...

  Functional Programming For Object Oriented Programmers

After recently remarking about how I finally "got" functional programming I was asked by one of my millions of twitter followers... ¬_¬ to write up an explanation of a small F# program spoken in terms that fellow O-O programmers would understand. Before I become too entrenched into the functional programming way of thinking, that is, and can't explain it anymore. As a former tutor this is one of the major problems with being able to teach something once you understand it. You've ...

  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...

  Prototypes in JavaScript

Following on from his previous article, David Chisnall explores JavaScript as an example of prototype-based object orientation. In this article, he shows how it's possible to implement more complex object models on top of this simple abstraction.My previous article, Prototypes and Object Orientation, considered the differences between class-based and prototype-based object orientation. In this article, we'll look in a bit more detail at the workings of the JavaScript object model, since it'...

  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...

  What Sort of Projects Can You Work on Using Web Scraping?

Image Source: Unsplash Web scraping is a technique used to extract large amounts of data from websites and save onto your computer in a database or time table format.

Before you start using your programming skills to find and extract inform...

  JSON in JavaScript

When sending an AJAX request to the server, the response can have two formats : XMLHttpRequest.responseXML to access data with XML format and XMLHttpRequest.responseText to access data with string format. XML is the standard data transfer format, but one weakness is it's troublesome to parse and retrieve the data. JSON(JavaScript Object Notation) is a light weight data interchange format, we call it the JavaScript object representation. The advantage of using JSON as the data format is itself is...
