Nokia Lumia 800 Review

AddThis Social Bookmark Button
I have two Windows Phone 7 devices, one of them is the HTC 7 Pro and the other one is the Nokia Lumia 800. I was using HTC 7 Pro for quite a long time but when I received Nokia Lumia 800 by participating in the Microsoft iUnlockJoy program, I am using that only.   Few people asked me to write a review on Windows mobile phones and hence I decided to write a small review on my current experience on Nokia Lumia 800. This post will cover specification of Nokia Lumia 800 and my review on that.
        When I first received the box, I found it very slim and light weighted other than the HTC 7 Pro which has a Querty keyboard inside and thus makes it heavy. First thing that I gone thru was the specification and here is that for you.   Nokia Lumia 800 Specification:   Operating System Windows Phone 7.5 (Mango) ...(Read whole news on source site)

Teaching kids electronics, electricity, and logic using littleBits

We homeschool our two children. Ben, is kindergarten age, Abby is pre-school age. My wife does, by far, most of the work there, including trucking them to specialized classes (art, music, gymnastics, karate, our homeschool group single day school, etc.) plus all the playdates with the other kids, and special events. Melissa even teaches several of the classes at the home school group. I generally deal with reading, since I'm in charge of story time with my son. Lately, we've split our time between him reading stories to me (I'm proud to say he's at about a 2nd grade level - you have to love personal tutoring) and me
reading The Hobbit to him in preparation for the movie this Christmas. (JRR Tolkien is far wordier than I remember.) Melissa and I also split science duties. I've brought Ben to the Banneker planetarium for a customized class arranged for our homeschool group in concert with one of the astronomy professors. I often bring Ben to SERC (Smithsonian Environmental Research Center) for their bi-weekly homeschool science class. It's nice to leave close to centers like that. Even in the 5-7 year old group, they do serious science. They worked with Microscopes to analyze feathers to explain what holds them together, learned about the scientific method, dissected something (unfortunately...(Read whole news on source site)

Go to definition in JavaScript feature of Visual Studio 2011 beta

AddThis Social Bookmark Button
This blog post will be a part of Visual Studio 2011 Beta feature series. In recent days I am exploring the Visual studio features and this blog post is also part of that. I am loving visual studio 2011 beta more and more after exploring features that make developer’s life easy. Today I am going to talk about one of the features that is going to make developer’s life easy. JavaScript is a
client scripting language which is an integral part of any web application now days.  So if you are web application developer you are surely going to write lots of JavaScript those days.  With earlier version of visual studio navigating code in JavaScript is not easy. But in visual studio 2011 beta we have go to definition features which one of most favourite features of visual studio for visual C#. Here is the screen shot for that. I am navigating in JavaScript code in ASP.NET MVC 4 application. That’s it hope you liked it. Stay tuned...(Read whole news on source site)

Windows 8, Metro, and Windows RT

AddThis Social Bookmark Button
As Microsoft moves toward the release of their new operation system(s), there continues to be some real confusion about terminology and features. I recently was asked by the author of a college textbook to help explain what is happening in the Microsoft space. Below is my response to him. A good description of what is happening can be found in Brandon LeBlanc’s blog. Windows 8 is the official name for the product that supports x86/64 architectures. Remember that these architectures can be found in both desktop machines and tablets so it is important not to associate Windows
8 with just desktops. In fact, Windows 8 will include two “modes”. One mode is the classic “desktop” mode and should be viewed as an upgrade from Windows 7. There are no restrictions on storing data or consuming resources because it is assumed that the machine will be connected to external power. However, the other mode, called the “Metro” mode, will restrict applications in terms of the resources they can use and will change how the user will interact with the application. Some of the restrictions include not supporting databases on the client and requiring all communications to be...(Read whole news on source site)

Membership Provider Parte 2. Creación de un Modelo de Bases de datos

AddThis Social Bookmark Button
En mi post anterior se hablaba sobre la importancia del Membership Provider de asp.net y algunas de sus funciones. Sin embargo, para los que ha usado el proveedor se habrán dado cuenta de que contiene muchas tablas, procedimientos, vistas y demás que en muchas ocasiones no utilizamos o se nos dificulta modificar por su complejidad. Así que, tomando en cuenta la facilidad con que contamos para personalizar el proveedor, empezaremos creando un modelo bastante sencillo que contendrá  4 tablas: Users, Roles, Profiles y Application. Con estas 4 tablas tendremos todo lo necesario para poder manejar los modelos de autenticación
y seguridad en una aplicación de asp.net En nuestro caso, este proveedor será de uso común, así que lo crearemos en Entity Framework para posteriormente poder manejar la implementación del código mediante LINQ. Primer paso, creando el esquema de Entity * Abrir visual studio * Seleccionar archivo-nuevo * Seleccionar proyecto * En el menú izquierdo, en plantillas instaladas seleccionamos Visual C#-Windows-Biblioteca de Clases *  Le ponemos un nombre y la agregamos al proyecto. Por defecto se crea una clase llamada Class1 la cual podemos eliminar * Ahora que tenemos el proyecto, damos...(Read whole news on source site)

Windows Phone: Performing long-running, timed operations on the UI thread

AddThis Social Bookmark Button
source: kuchenzeit.wordpress.com Recently I had to play timed sounds (morse code) in a WP7 applications. Sounds are required to be played on the UI thread, but as I had to time them, my UI thread got frozen. The reason was, that I used Thread.Sleep() to time the sound, which of course blocked the UI thread. Today I figured out a way to do this long-running operation (many seconds..) without blocking the UI thread. You may know the Visual Studio Async CTP – it’s required to do the trick. Let’s suppose we already have a method InvokeEvent() that plays the sound,
changes a color or something like that. Currently we execute this method in a pattern like this, causing the UI thread to be blocked: void StartOperation()//invoke the event in a pattern { for (int i=0; i<20 ; i++)//20 times { InvokeEvent();//play the sound, blink with the display or something like that Thread.Sleep(500);//this will block the current (UI) thread! InvokeEvent(); Thread.Sleep(150); } } ...Read more ...(Read whole news on source site)

Catch Exceptions in Concurrent Flows Using Causalities

AddThis Social Bookmark Button
The previous article showed you how to easily parallelize flow operation execution with NPantaRhei (download the sources from github). Once operations run concurrently, though, you´ve to pay your dues. Benefits or concurrent execution like higher performance, lower latency, or increased throughput come at a price. What that means conceptually e.g. for access to shared data, I leave to you to research. Here I want to show you how to practically handle errors in such flows. Because error handling cannot rely on the usual try-catch statement, you need to take care of it in your flow
definition. Causalities: Contexts for Exceptions The question is: How to catch exceptions when there is no call stack anymore? You could do it by providing each operation with its own exception port and catch the exceptions yourself. This is ok, if you don´t want to check on too many operations. But what if an exeption occurs in an unchecked operation? One that you thought would not fail? Wouldn´t it be better to just be able to say: “From here on, however the data flows, if an exception occurs, it should be handled such and such.” That´s...(Read whole news on source site)
