YouTube Playlists for Learning Programming YouTube has been very good platform for learning any thing. Earlier you have seen 400+ courses on YouTube and 130+ NPTEL courses. There are few more courses especially about computer programming. These are contributed by various individuals. thenewboston: thenewboston is a great youtube channel, has more than 2o playlists covering topics Python, C, Java, iPhone development and web programming like HTML, CSS, PHP. Xoax.net Xoax has more than 200 videos but mainly focuses on C++. PHPacademy As the name suggests, it focuses mainly on PHP and some on MySql. There are more videos on small projects like writing your own search engine for your database, pagination, creating a rating system etc… Related posts: Get more stuff like this

Dot.Blog | MVVM : Gérer les données de Design de façon propre Read this article in your language IT | EN | DE | ES De Silverlight à WinRT en passant les Smartphones, sous Windows ou d’autres OS, les patterns de type MVVM sont devenues indispensables. Toutefois gérer des données de Design pour faciliter la création des UI est souvent mal géré ou oublié. MVVM “Générique” Il existe de nombreux frameworks pour gérer la séparation UI/Code, qu’ils soient basés sur MVVM, MVC ou d’autres patterns. C’est à la fois attirer votre attention sur le principe de fournir des données de design qui m’intéresse ici et la mise en œuvre de moyens simples réutilisables dans une multitude de contextes (quitte à les adapter). Silverlight L’exemple pourrait être fait avec WinRT, WPF, WP7 ou WP8 ou même d’autres technologies, cela n’a pas grande importance. Principes de base des données de design Tout d’abord j’aimerais insister sur la nécessité de proposer des données de design. Les données de design doivent être : Il ne s’agit que des grands principes de base. Lorem Ipsum

Codecademy Labs Dot.Blog | De la bonne utilisation de Async/Await en C# Read this article in your language IT | EN | DE | ES [new:30:06/2014]Async et Await simplifient l’écriture des applications qui doivent rester fluides et réactives. Mais cela suffit-il à rendre les applications multitâches ? Async et Await Pour ceux qui éventuellement auraient loupé un épisode important des aventures de C#, sa vie, son œuvre en 5 tomes, voici un bref résumé de ce que sont les mots clés Async et Await et ce à quoi ils servent. C’est une question de méthode… De nombreuses méthodes ne retournent pas immédiatement le trait, elles peuvent effectuer des tâches assez longues, comme accéder à des ressources extérieures (Web, réseau, appareil de mesure externe ou interne tel le compas, le GPS, l’accéléromètre…). Toute méthode exécutée sur le thread principal bloque logiquement ce dernier or il est utilisé par l’OS pour gérer l’interface. Les threads ne sont pas des tâches De fait, les threads ne sont pas des tasks… async et await Fixons les choses asynchronisme ! Asynchronisme ! Run(menu);

Editing Editing refers to the changing of a page by a Wikimedia user. Unless certain restrictions are in effect, such as protection, all pages are editable, by everyone. This is a brief overview of that process. Most frequent Wiki markup explained Restrictions Some pages cannot be edited by everyone. If a page is semiprotected, it can be edited by everyone except IPs and accounts that have not yet been confirmed.If a page is fully protected, only other admins can make edits to the page.A page can also be protected so that it cannot be moved.In some cases, an admin might see fit to protect a page from being created.For very rare pages, such as the Main Page, "cascading" protection is applied, wherein every page that is transcluded onto a page is protected too. There are various reasons why a page might be protected.

Share code between WPF and Universal Apps with PRISM This will be a series of blog posts that deals with sharing code and XAML between WPF and Universal Apps. This first part is about the basic project set-up and sharing ViewModels. In following parts we will take a look at sharing XAML (with a preprocessor) and unifying concepts such as navigation. Intro We have so many platforms to code for these days: windows desktop, tablets, phones, the web, even xbox. One of the issues stemming from this abundance is that there are a ton of SDKs that have quite similar APIs, but also some subtle and not-so subtle differences that make cross-platform development a real pain. Having said that, it is worth noting that the new “Universal Apps” are a huge step in the right direction. With Silverlight going away focus is coming back to WPF with great force. Traditional desktop apps are substantially more different than apps for phones/tablets but there is nothing wrong with trying to share code, especially if you are targeting both platforms. The Basics

6 Books Every Programmer Should Own I’ve seen many lists about the best programming books and I am sure there are a lot of books that are specific to a programming knowledge or technology – that I have not included in my list. The books I have chosen are those that are meant to inspire, increase productivity and improve your programming design skills. Note: This list has no particular order. Code Complete 2 Steve McConnell The main focus of this book to help you improve your programming design skills. The Pragmatic Programmer: From Journeyman to Master Andrew Hunt and David Thomas This book focuses on the best practices of programming (i.e. what you should and should not do). Pragmatic Thinking and Learning: Refactor Your Wetware Andy Hunt From the author of The Pragmatic Programmer, this book takes one-step back from programming and focuses on your everyday thinking and problem solving skills. The Productive Programmer Neal Ford and David Bock Algorithms in a Nutshell George T Heineman, Gary Pollice and Stanley Selkow Thomas H.

Multi-Targeting .NET Standard Class Libraries | Gigi Labs The .NET family has grown quite a bit, and to be honest, it’s a bit of a confusing mess. As I already explained in “Migrating Dandago.Finance to .NET Core“, there are now several different types of class library you can choose from (including different kinds of portable class libraries), different ideas of cross-platform (.NET Core vs Universal Windows Platform), different frameworks, and .NET Standard. Let’s consider the following image, which shows three different .NET-based frameworks in relation to .NET Standard: Image credit: .NET Core, .NET Framework, Xamarin – The “WHAT and WHEN to use it” Your applications will typically be built for one of the frameworks on top (e.g. .NET Framework). This means that class libraries that target .NET Standard have maximum compatibility, but there’s a cost: not all APIs are available for .NET Standard, and targeting .NET Standard is only compatible with certain recent versions of those frameworks. For the most part, this is okay.

30 free programming eBooks - citizen428.blog() Since this post got quite popular I decided to incorporate some of the excellent suggestions posted in the comments, so this list now has more than 50 books in it. BTW: I’m not very strict on the definition of “ebook”, some of them are really just HTML versions of books. [UPDATED: 2012-01-18] Learning a new programming language always is fun and there are many great books legally available for free online.

.NET Framework Development Guide This section explains how to create, configure, debug, secure, and deploy your .NET Framework apps. The section also provides information about technology areas such as dynamic programming, interoperability, extensibility, memory management, and threading. .NET Framework Class Library Supplies syntax, code examples, and usage information for each class that is contained in the .NET Framework namespaces. Apriori Algorithm Download Source Code Introduction In data mining, Apriori is a classic algorithm for learning association rules. Apriori is designed to operate on databases containing transactions (for example, collections of items bought by customers, or details of a website frequentation). Other algorithms are designed for finding association rules in data having no transactions (Winepi and Minepi), or having no timestamps (DNA sequencing). Overview The whole point of the algorithm (and data mining, in general) is to extract useful information from large amounts of data. Support: The percentage of task-relevant data transactions for which the pattern is true. Support (Keyboard -> Mouse) = Confidence: The measure of certainty or trustworthiness associated with each discovered pattern. Confidence (Keyboard -> Mouse) = The algorithm aims to find the rules which satisfy both a minimum support threshold and a minimum confidence threshold (Strong Rules). Item: article in the basket.
