Linux namespaces make it possible to run a whole range of applications on a single real machine and ensure no two of them can interfere with each other, without having to resort to using virtual machines. In a single-user computer, a single system environment may be fine. But on a server, where you may want to run multiple services, it is essential to security and stability that the services are as isolated from each other as possible.Continue reading →
CakePHP is an amazing PHP framework, but it has a steep learning curve! It requires a good amount of research and training to become an expert.
This article describes few bad practices when writing a CakePHP code, and proposes the correct approach to avoid them.Continue reading →
ESA’s Rosetta mission soft-landed its Philae probe on a comet, the first time in history that such an extraordinary feat has been achieved. Closely after that, Microsoft Open Sourced .NET.
The first event is a great step for mankind, and the latter is even greater for Microsoft!Continue reading →
As is known worldwide, the Chinese government enforces strict censorship on the internet. Virtually everything is under the government’s surveillance. In order to be allowed to operate, ISPs and internet content providers in China usually have their own content filtering mechanism for blocking or removing the published content by its users, or even deleting users’ account directly if they are assumed to be illegal under the government policy.Continue reading →
There are thousands of different Android powered devices, with different screen sizes, chip architectures, hardware configurations, and software versions. Unfortunately, segmentation is the price to pay for openness, and there are thousands ways your app can fail on different devices.
Regardless of such huge segmentation, the majority of bugs are actually introduced because of logic errors. These bugs are easily prevented, as long as we get the basics right!
Here’s a quick rundown of the 10 most common mistakes Android developers make.Continue reading →
Git can support your project not just with version control, but also with collaboration and release management. Understanding how workflow patterns can help or hinder a project will give you the knowledge to evaluate and adapt your project’s Git processes effectively.Continue reading →
Wouldn’t it be great to develop for Google Glass without learning a new programming language, and even by just using knowledge common to all web developers? Yes, it is possible!
This article will introduce you to web development techniques you can use to build application used on Google Glass.Continue reading →
Since Apple’s launch of Swift this past June, many iOS developers have been struggling with the question of if, how, and when to transition from Objective-C to Swift. This article explores some important points to consider before jumping into Swift development.Continue reading →
Why are Rails Engines not used more often? I don’t know the answer, but I do think that the generalization of “Everything is an Engine” has hidden the problem domains that they can help to solve.Continue reading →
After 6 years of improving and working on Objective-C, Apple decided to throw another challenge at developers. Once again, iOS developers will need to learn a new programming language: Swift.
Swift 1.0 is already a stable and strong development platform, which is sure to evolve in interesting ways over the coming years. It is a perfect moment to start exploring this new language, as it is the future of iOS development.Continue reading →
One of the most capable, extensible and popular front-end frameworks is AngularJS, and one of the most useful components of the AngularJS framework is something called a directive. In this article, the four functions that execute as a directive is created and applied to the DOM will be explored.Continue reading →
How do we understand and interpret the huge amounts of data coming out of simulations? How do we visualize potential gigabytes of datapoints in a large dataset? In this article I will give a quick introduction to VTK and its pipeline architecture, and go on to discuss a real-life visualization example.Continue reading →
It’s been over 20 years since Tim Berners-Lee and Robert Cailliau specified HTML, which became the standard markup language used to build the Internet.
HTML5 was supposed to finally solve our problems and become “one standard to rule them all (browsers)”. This was probably one of the most anticipated technologies since creation of the World Wide Web.Continue reading →
React.js is a fantastic library. It is only one part of a front-end application stack, however. It doesn’t have much to offer when it comes to managing data and state. Facebook, the makers of React, have offered some guidance there in the form of Flux. I’ll introduce basic Flux control flow, discuss what’s missing for Stores, and how to use Backbone Models and Collections to fill the gap in a “Flux-compliant” way.Continue reading →
Today we have thousands of digital and printed resources that provide step-by-step instructions about developing all kinds of different web applications. Development environments are “smart” enough to catch and fix many mistakes that early developers battled with regularly. There are even many different development platforms that easily turn simple static HTML pages into highly interactive applications.
All of these development patterns, practices, and platforms share common ground, and they are all prone to similar mistakes caused by the very nature of web applications.Continue reading →
Hoodie is a progressive new library for front-end developers that adopts some remarkable new philosophies. Hoodie puts the control over app design completely in the hands of the front-end developers and user-experience experts, and frees users from the bonds of un-interruptible connectivity.Continue reading →
Data conversion, translation, and mapping is by no means rocket science, but it is by all means tedious. This article introduces MetaDapper, a .NET library that strives to simplify, streamline, and automate the data conversion process to the greatest extent possible.Continue reading →
Google Glass promises to revolutionize how we use our devices to interact with the world. But from a developer’s standpoint, what is so special about developing for the Glass? You’ll be glad to know that the answer is “Nothing!” Here’s a step-by-step tutorial that walks you through developing your first Google Glass app.Continue reading →
The popularity and usage of Scala is rapidly on the rise, as evidenced by the ever-increasing number of open positions for Scala developers.
