Storm Documentation. In this tutorial, you’ll learn how to create Storm topologies and deploy them to a Storm cluster.
Java will be the main language used, but a few examples will use Python to illustrate Storm’s multi-language capabilities. Preliminaries This tutorial uses examples from the storm-starter project. It’s recommended that you clone the project and follow along with the examples. Read Setting up a development environment and Creating a new Storm project to get your machine set up.
Components of a Storm cluster A Storm cluster is superficially similar to a Hadoop cluster. There are two kinds of nodes on a Storm cluster: the master node and the worker nodes. Each worker node runs a daemon called the “Supervisor”. All coordination between Nimbus and the Supervisors is done through a Zookeeper cluster. Topologies To do realtime computation on Storm, you create what are called “topologies”. Creating a Basic Windows Service in C# Download source - 3.78 Kb Introduction Do a search some time on Google for Services and C#, and you'll come across a lot of ASP.NET references for web services.

ViewStateUserKey and "Invalid_Viewstate" when posting back during Forms Authentication. Troubleshooting Expired ASP.NET Session State and Your Options. My TurboTax. Getting. Learn.knockoutjs.com. In this first tutorial you'll experience some of the basics of building a web UI with the Model-View-ViewModel (MVVM) pattern using knockout.js.
You'll learn how to define a UI's appearance using views and declarative bindings, its data and behavior using viewmodels and observables, and how everything stays in sync automatically thanks to Knockout's dependency tracking (even with arbitrary cascading chains of data). Using bindings in the view In the bottom-right corner, you've got a viewmodel containing data about a person.
In the top-right corner, you've got a view that's supposed to display the person data. Right now it just displays "todo", so let's fix that. Modify the two <strong> elements in the view, adding data-bind attributes to display the person's name: <p>First name: <strong data-bind="text: firstName"></strong></p><p>Last name: <strong data-bind="text: lastName"></strong></p> Running the code.

This is not possible if using the Microsofts OLE DB .NET Data Provider. So the properties are specified in the connection string instead. PLSQLRSet: If the stored procedure, provided by the consumer, returns a rowset, PLSQLRSet must be set to TRUE (enabled). NDatatype: This property allows the consumers to specify whether any of the parameters bound to the command are of Oracle's N datatypes (NCHAR, NVARCHAR or NCLOB). This information is required by OraOLEDB to detect and bind the parameters appropriately. SPPrmsLOB: This property allows the consumer to specify whether one or more of the parameters bound to the stored procedures are of Oracle's LOB datatype (CLOB, BLOB, or NCLOB). Oracle/PLSQL. Oracle is a relational database technology developed by Oracle.
PLSQL stands for "Procedural Language extensions to SQL", and is an extension of SQL that is used in Oracle. PLSQL is closely integrated into the SQL language, yet it adds programming constructs that are not native to SQL. Oracle Programming/SQL Cheatsheet. This "cheat sheet" covers most of the basic functionality that an Oracle DBA needs to run basic queries and perform basic tasks.
It also contains information that a PL/SQL programmer will frequently use to write stored procedures. The resource is useful as a primer for individuals who are new to Oracle, or as a reference for those who are experienced at using Oracle. A great deal of information about Oracle exists, scattered throughout the net. This resource was developed in order to make it easier for programmers and DBAs to find most of the basics in one place. When a topic is beyond the scope of a "cheatsheet" a link is generally provided for further research. Other Oracle References. Khan Academy. Financial Dictionary. Google. Browser back button issue after logout. Well, I found a lot of people asking for a resolution to handle the browser's back button once user has logged out.
Typically, users report something like: Optimizer. RequireJS has an optimization tool that does the following Combines related scripts together into build layers and minifies them via UglifyJS (the default) or Closure Compiler (an option when using Java).Optimizes CSS by inlining CSS files referenced by @import and removing comments.
The optimizer is part of the r.js adapter for Node and Rhino, and it is designed to be run as part of a build or packaging step after you are done with development and are ready to deploy the code for your users. The optimizer will only combine modules that are specified in arrays of string literals that are passed to top-level require and define calls, or the require('name') string literal calls in a simplified CommonJS wrapping. So, it will not find modules that are loaded via a variable name: var mods = someCondition ? But 'a' and 'b' will be included if specified like so: Installing and Running node.js applications within IIS on Windows - Are you mad? Samples. SecuringErrorLogPages - elmah - How to securely the error log pages from unauthorized users - Error Logging Modules and Handlers for ASP.NET.

Why is this so important? See ASP.NET session hijacking with Google and ELMAH. Enabling or Disabling Remote Access ELMAH provides a configuration section and a setting to enable or disable remote access to the error log display and feeds. Remote access is enabled when the value of the allowRemoteAccess attribute is either 1, yes, true or on. Note: Make sure you have declared the expected configuration sections in order to apply the above configuration. ASP.NET MVC from Basics to Tips and Tricks.

Writing Fast, Memory-Efficient JavaScript. Advertisement JavaScript engines such as Google’s V81 (Chrome, Node) are specifically designed for the fast execution2 of large JavaScript applications. As you develop, if you care about memory usage and performance, you should be aware of some of what’s going on in your user’s browser’s JavaScript engine behind the scenes. You should, however, ask yourself questions such as: Is there anything I could be doing more efficiently in my code? What (common) optimizations do popular JavaScript engines make? The Node Beginner Book » A comprehensive Node.js tutorial. CSS3 Media Queries. CSS2 allows you to specify stylesheet for specific media type such as screen or print. Now CSS3 makes it even more efficient by adding media queries.
You can add expressions to media type to check for certain conditions and apply different stylesheets. For example, you can have one stylesheet for large displays and a different stylesheet specifically for mobile devices. It is quite powerful because it allows you to tailor to different resolutions and devices without changing the content. Continue on this post to read the tutorial and see some websites that make good use of media queries.
