Service Account Management in SharePoint 2013

SharePoint, WCF and Azure Trainings: more information My newest article detailing Service Account management in SharePoint 2013 is now online. Who thought such a simple need could have so many nuances. Hope you like it With this, I am going to do a break – not taking time off, but switching gears. My next series of Articles are going to focus on writing Mobile Apps for SharePoint and Office 365. And I intend to cover every single scenario, On Prem, Cloud, Xamarin, HTML5, Cordova, and Native. I will show Windows and iOS, I’m an android dumbass, but space/time permitting I may show cordova android – anyway, for an Android guru the articles will provide enough information get rolling anyway.

A* how make natural look path?

- by user11177

I've been reading this: http://theory.stanford.edu/~amitp/GameProgramming/Heuristics.html But there are some things I don't understand, for example the article says to use something like this for pathfinding with diagonal movement: function heuristic(node) = dx = abs(node.x - goal.x) dy = abs(node.y - goal.y) return D * max(dx, dy) I don't know how do set D to get a natural looking path like in the article, I set D to the lowest cost between adjacent squares like it said, and I don't know what they meant by the stuff about the heuristic should be 4*D, that does not seem to change any thing. This is my heuristic function and move function: def heuristic(self, node, goal): D = 10 dx = abs(node.x - goal.x) dy = abs(node.y - goal.y) return D * max(dx, dy) def move_cost(self, current, node): cross = abs(current.x - node.x) == 1 and abs(current.y - node.y) == 1 return 19 if cross else 10 Result: The smooth sailing path we want to happen: The rest of my code: http://pastebin.com/TL2cEkeX

What is Pseudocode?

- by Jae

I've seen a lot of mentions of Pseudocode lately, on this site and others. But I don't get it: What is Pseudocode? For example, the Wikipedia article below says "It uses the structural conventions of a programming language, but is intended for human reading rather than machine reading." Does this mean that it isn't actually used to make programs? Why is it used? How is it used? Is it considered a Programming Language? See the above Wikipedia quote. Is it commonly known/used? Anything else... I honestly don't know where to start with this. I have Googled it and I've seen the Wikipedia article on the topic, but I still don't fully understand what it is.

How to choose a language, when taking in account the community it includes?

- by Rick Rhodes

I was reading the following article: Great Hackers The following part grabbed my attention: "When you choose a language, you're also choosing a community. The programmers you'll be able to hire to work on a Java project won't be as smart as the ones you could get to work on a project written in Python. And the quality of your hackers probably matters more than the language you choose. Though, frankly, the fact that good hackers prefer Python to Java should tell you something about the relative merits of those languages." I would like to apply his advice on a commercial web application I am building (I am a strong believer in culture and community), yet this article was written in 2004, and python has increased in popularity in the recent years. How can I decided a language when taking in consideration its community, rather than the popularity? Any recommendations? Is there any language community that show dedication and passion for developing, rather than learning a language to get a Job and a paycheck?

LightView: JavaFX 2 real-time visualizer for GlassFish

- by arungupta

Adam Bien launched LightFish, a light-weight monitoring and visualization application for GlassFish. It comes with a introduction and a screencast to get you started. The tool provides monitoring information about threads and memory (such as heap size, thread count, peak thread count), transactions (commits and rollbacks), HTTP sessions, JDBC sessions, and even "paranormal activity". In a recently released first part of a tri-part article series at OTN, Adam explains how REST services can be exposed as bindable set of properties for JavaFX. The article titled "Enterprise side of JavaFX" shows how a practical combination of REST and JavaFX together. It explains how read-only and dynamic properties can be created. The fine-grained binding model allows clear separation of the view, presentation, and business logic. Read the first part here.
