Supercharge Your Javascript with Optimized DOM Manipulation

by

This year I worked on a project which involved populating a huge HTML table (up to 1,048,576 rows by 16,384 columns) cell-by-cell, with data retrieved via ajax calls. Needless to say, performance was not good.

Creating Custom stencils for Omnigraffle ( the right way )

by

Recently I have been using Omnigraffle for creating wireframes. I like using Omnigraffle because it offers a lot of flexibility in terms of styling the wireframes, while being quite simple to use.

Another great thing about Omnigraffle is the Graffletopia stencil library. This extensive resource includes many commonly used design elements and icons – you can download it from http://www.graffletopia.com.

Writing a Secure Android App

by

When it comes to developing an Android app that deals with sensitive information, you must take extra precautions to make sure that the information doesn’t fall into the wrong hands. Although Android devices come with state-of-the-art security features, app developers often don’t leverage them. Even if they do, they may not necessarily be using them properly. One simple security hole is all it takes to compromise your app’s security as well as the security of the servers/systems it’s connecting to.

A Software Consulting Conundrum: Providing Estimates While Staying Agile

by

Software Estimates

As a software consulting firm, Grio strives to provide high quality, high value software to its clients. We embrace an agile software development methodology based on Scrum. This iterative approach provides our clients with flexibility to adapt and change their product over the course of development as discoveries are made while using the software.

This flexibility can prove challenging when providing up front estimates regarding project costs. The problem arises that providing an estimate that is too high may lose you the contract; Estimating too low can result in several outcomes:

Adventures in Unity

by

Constructing our next internal video game (Whack Attack) in the Unity software system has been a joyful experience and a return to my roots as a video game programmer. Instead of dealing with tables and lists for an enterprise web application, I find myself programming mole AI and hit reactions. As an internal project, the few hours a week I get to spend making cartoon mammals run around my phone are a welcome diversion, and makes my return to client work that much more satisfying.

Testing UI in iOS….and some Gotchas

by

Most times in your application  a solid unit test trumps testing your UI. But that’s no reason to neglect your UI from having to endure the same rigorous testing you give your models. “But I don’t have time to sit around and tap every part of my application.”, you say. Enter Automation…

Turn Your Macbook into a Blender

by

A decade or so ago the idea of running a full 3D software suite on a mac laptop was pretty much unheard of. Processor speed and memory were the greatest obstacles, and the aggregate of 3D software for the Macintosh platform was rather limited, as well as expensive.

Unit vs. Acceptance Testing (Part 1)

by

You don’t know the power of Test Driven Development

As a recent convert to Test Driven Development (or TDD as his friends call him), I was surprised to hear that there were in fact 2 kinds of developer driven testing.  The standard one that everyone knows of is unit testing:  writing little testXXX methods that test a single publicly exposed method.  But the lesser known – but just as important – are acceptance tests:  tests which verify that  a group of classes working together properly fulfill some functionality.

So this first post will take a closer look at the first type of testing, unit tests, and will go into the value it provides to you as a developer.

A Lightweight jQuery Notification Bar

by

Notifying users with quick messages and alerts in a website is one of the most recurring needs of a web developer.
Every time I need to implement something like that, I start looking around the web hoping to find some Javascript/jQuery plugin that would do the work for me.
The good thing is that a lot of people have already faced this problem.
The bad thing is that the results of the search are way too many and often very confusing.
Chances are that most of the time, you don’t really need a 3MB-super-fancy-hyper-customizable-highly-priced plugin, but you just want something that works, and that you can quickly incorporate into your code.
