  1. How to read and parse a CSV file using Node.JS

    I was recently asked by someone to give an example of how to read a csv file in their node.js application, and how to parse it to get it to be usable in their app. In fact what they wanted to do is very simple, and it is one of the many reasons I'm a big fan of Node.js, because not only can it do things like this in a few lines of JavaScript, it does it server side, and fast. So This article lays out step by step how to have node.js read and parse a CSV file stored in it's project, by using the CSV...
  2. Software Reengineering: From Spaghetti to Clean Design

    “Can you take a look at our system? The guy who wrote the software isn’t around anymore and we’ve been having a number of problems. We need somebody to look it over and clean it up for us.”Anyone who’s been in software engineering for a reasonable amount of time knows that this seemingly innocent request is often the beginning of a project that “has disaster written all over it”. Inheriting someone else’s code can be a nightmare, especially when the code is poorly designed and lacks documentation.
  3. Programming languages - salaries and demand (3rd Quarter 2015)

    <span style="font-size: 0.7rem; display: block; text-align: center;">* Overall salary trends for the last two quarters.<br />N.B. Salaries for each country have been converted to USD for ease of comparison.*</span>Overall global salaries are down by $5,000 - $10,000 USD over the last quarter. Relative positions in popularity however remain mostly the same. By almost any measure and ranking methodology, the most popular and well paid languages are still JavaScript, Java,...
  4. 8 Essential Backbone.js Interview Questions

    With Backbone.js, collections can be sorted by defining comparator on the collection object. By default, collections are not explicitly sorted. By defining a comparator, a collection is sorted whenever a model is added or the “sort()” method is invoked on a collection:var Fruits = Backbone.Collection.extend({})// Orvar Fruits = Backbone.Collection.extend({})var fruits = new Fruits()fruits.comparator = function(a, b) { /* .. */ }The comparator property can be a function with one argument (similar...
  5. Programming languages - salaries and demand (May 2015)

    Here is what happened to the software development market in May 2015. For previous months, take a look at the Gooroo Insights series.We are currently analysing ~500,000 tech jobs every single month, half of which are in the software development area. This provides a unique dataset which can tell us what skills organisations are hiring for and what salaries they're advertising.C# was in first place in April but fell back down in May in terms of demand. This puts Java in the number one position again...

  7. Programming languages - salaries and demand (March 2015)

    We've released a few of these reports before, and here is the first for 2015. With our database now analysing ~500,000 tech jobs every single month, we have a unique dataset which can tell us what skills organisations are hiring for and what salaries they're advertising.This year we have seen quite a lot of change in the popularity of various programming languages. Whether this is a feature of different industry's hiring cycles is still to be determined.Battling for 1st position are Java and C# with...
  8. Another Top 10 Languages list for 2014

    Everyone seems to publish their Top 10 list at the end of the year. Some rely on stats from surveys, others look at how many GitHub projects use a certain language, whilst others are purely anecdotally based. They're all good ways to investigate the trends (except maybe the anecdotal version).Using our data which consists now of over 4,000,000 job ads in the United States, Great Britain, and Australia, we look at how often a particular skill is mentioned in ads.Immediately we notice that SQL has...
  9. Programming languages - salaries and demand (October 2014)

    A few months ago we wrote up a brief analysis of key programming languages, showing the demand for each language and the salaries being offered. We now have almost 3 million job advertisements in our analysis engine so we should take a fresh look at what it says.In July, we saw three main clusters, the established leaders, the followers, and the niche.The leaders of the group are still ahead in very much the same positions. Java, C++, and C all pay well and are in high demand. JavaScript and C# are...
  10. Angular JS, Backbone.js, or Ember.js - Which should you choose?

    There's been a lot written comparing these three frameworks. Instead of repeating what is already out there, I wanted to look at the battle from an employability perspective. Which framework has entered the paying marketplace, and how much will they pay you for it.Backbone.js came to developers in 2010. Over the last few years, demand has risen bringing it to the front of the pack with 5% more jobs advertised than AngularJS. When we look at individual countries, we find this lead only exists in the...
