Like many people in the Technology world I watched Apple's iPad announcement this week with intense interest. Unlike most people I am interested not in the consumer space - but rather how could this device be used for business. How could a new category like this be used? This post Apple Reaches for Greatness Without Apology first appeared on Dan Stroot's Blog

In our last primer we saw the Fourier series, which flushed out the notion that a periodic function can be represented as an infinite series of sines and cosines. While this is fine and dandy, and quite a powerful tool, it does not suffice for the real world. In the real world, very little is truly periodic, especially since human measurements can only record a finite period of time. Even things we wish to explore on this blog are hardly pe..

Se siete ai primi passi nello sviluppo di applicazioni web vi consiglio la lettura di SSH: What and How. Senza troppi fronzoli l’articolo spiega le basi di SSH mettendo bene in luce le possibilità offerte da questo importante strumento di lavoro. Ogni giorno molti sviluppatori web usano SSH (“Secure Shell”) per gestire i loro server, fare backup, lavorare in remoto e una miriade di altre cosette. Oggi vi spiego cos’è e da dove viene SSH..

Finding stories in your backlog, locating a bug that was logged last week and rediscovering the acceptance criteria on an older story all require a good search capability. The need to find specific cards more easily and consistently in a Mingle project, especially with a large number of cards, has been widely requested. And we’ve heard you.

If you're reading this, you may be attempting a large scale organizational change of some kind. And perhaps you are feeling overwhelmed at the huge amount of literature available in "the Google" about how to change a large organization.

You are a ninja-rockstar developer with a billion dollar idea. You write Ruby and Javascript. You like BDD, responsive design, HTML5 and node.js. You are really good at UX and quickly producing a prototype. You have been working on your app for a few months. Now it’s time to deploy your app. Because you are a hot new start-up, you will of course use AWS. You spend a few hours trying to figure out how many of which instance type you....

If you really care about your sanity and the sanity of those around you, you probably start most projects by creating a build script of some description. 1 If you've compiled Java or .NET, or if you read the Ant primer then you're probably familiar with writing an XML based build script. Adobe Flex application can be built in the same way, with just a few steps. Prerequisites Basic Compilation We'll start by creating a very basic build.

I thought I’d take a moment to present one possible path, or set of alternate paths, for learning Clojure, a modern Lisp implemented on top of the Java Virtual Machine. Update: Since this was written in 2012, a number of additional excellent books have come out. These include Carin Meier’s Living Clojure ; Vandgrift and Miller, Clojure Applied ; and Daniel Higginbotham’s, Clojure for the Brave and True . These are all great ch....

Problem: Derive the double angle identities $$\sin(2\theta) = 2\sin(\theta)\cos(\theta)\\\ \cos(2\theta) = \cos^2(\theta) – \sin^2(\theta)$$ Solution: Recall from linear algebra how one rotates a point in the plane. The matrix of rotation (derived by seeing where $ (1,0)$ and $ (0,1)$ go under a rotation by $ \theta$, and writing those coordinates in the columns) is $$A = \begin{pmatrix} \cos(\theta) & -\sin(\theta) \\\ \sin(\theta) & \cos(..

This is not going to be a very popular opinion considering my reader demographic, but I’ve grown a little sick of the gaming community as a whole and recent whining about Diablo 3 has triggered…well…this post. Why do so many of us have to be so negative about everything that comes out? Ok, I understand things like being frustrated about server downtime, or installation problems, or major bugs. I completely understand the frustration there..

CloudFlare is a both a proxy and a CDN (content delivery network). It was recommended to me by Magnus Bråth. Quoted from them: On average, a website on CloudFlare loads twice as fast uses 60% less bandwidth has 65% fewer requests is way more secure All for free! Never heard of them?
