Information Zalgo is a combination of 3 different character sets, Combining Diacritical Marks (U+0300 - U+036F), Greek and Coptic (U+0370 - U+3FF) and Cyrillic (U+0400 - U+04FF).
It is also known as a "meme" on sites like but is also argued to be a "curroption instead. Some websites and computers cannot read these characters even if they have UTF-8 enabled. If you can't see it then try going to "View > Character encoding / encoding > UTF-8". This can affect how fast sites load and how they look. Encyclopedia Dramatica : "The Zalgo outbreak has since been brought to greater attention by b3ta.com user Evilscary, who created/discovered most of the Garfield and Ctrl-Alt-Del comics featuring Z҉A҉L҉G҉O.
Writing user defined functions for Excel in .NET - .NET4Office. I've updated this article with some new guidance--for the details, see this post.
Excel enables the creation of user defined functions that can be used in Excel formulas. A developer must create a special kind of DLL called an XLL. Excel also allows you to write custom functions in VBA that can be used in Excel formulas. Unfortunately, Excel does not support or recommend writing an XLL that uses managed code. If you are willing to take your chances that your XLL might not run in current or future versions of Excel, there are solutions available that enable this scenario—search the web for “managed XLL”. Fortunately, there is an easier way to create a user defined function that doesn’t require you to create an XLL dll. First, launch Visual Studio 2005 or Visual Studio 2008 and create a new C# class library project called AutomationAddin for this example. Then, in your Class1.cs file, enter the code shown below. Using System;using System.Runtime.InteropServices;using Microsoft.Win32; OSP Programming Overview. » home » OSP Programming » Overview Physics Pedagogy and Computer Science The continued use of procedural languages in education is due, in part, to the lack of up-to-date curricular materials that combine science topics with an object-oriented programming framework.
Although there are many resources for teaching computational physics, few are object-oriented. What is needed by the broader science education community is not another computational physics, numerical analysis, or Java programming resource (although such resources are essential for discipline-specific practitioners), but a synthesis of curriculum development, computational physics, computer science, and physics education that will be useful for scientists and students wishing to write their own simulations and develop their own curricular material.
The OSP code library and OSP examples meet this need. OSP Library The OSP Library is distributed under the terms of the GNU General Public License. DataGen - Test data generator.
C# Community. Code.nasa.gov. How to: Request a Web Page and Retrieve the Results as a Stream. Windows Phone 7.5 - Manipulating camera stream. In the previous article from this series I've introduced how to access the cameras of the phone and emulate a photo camera using the Windows Phone API.
These API are really straightforward and almost everyone can take pictures easily for the purposes of the application. But for the most demanding, taking pictures does not suffice. As an example you can think to an application that needs to measure the light incoming from the lens or that is able to read a barcode without asking the user to click a button. These two samples, but also lot of other I can imagine, require the access to the raw stream coming from the camera. Only in this way the developer can examine the stream, detect shapes, perform calculations, and so on. Download the source code Accessing the raw stream For the purpose of demonstrating how to access the camera stream, I've created a simple histogram calculator app. 1: public Histogram() 3: InitializeComponent(); 5: // add here further initializations.
