Credit card numbers
Credit card numbers that conform to the Luhn formula (MOD 10 check). Usefull for testing e-commerce sites (because they should get past any pre-validation you do, and be declined at the card processor or bank stage).
In testing situations any expiry date within the next 3 years should work.

Комфортная еда
Оказывается, мода на рецепты по ГОСТу и прочую кулинарную реконструкцию - это старый мировой тренд и называется он comfort food. По ссылке в вики-статье все сказано, я просто резюмирую вкратце - термин появился в конце семидесятых и охватывает целый пласт кулинарии от ностальгичиского до культурного. Любая еда, дающая человеку психологическое чувство покоя и защищенности, является комфортной:

All about .NET Timers - A Comparison
Threads and Timers are the most common things that you need for your application. Any work that needs to be done in background without intervening the work that is running in the foreground needed to be done using a Thread. We create Threads to delegate a long running process in background so that the UI remains unblocked. Timers on the other hand are a special module which runs after a certain interval of time in background. So you would think Timers will also create a new Thread in background and run the module associated with it after a certain time. This is not always true.In this post, I will compare most of the timers available with .NET right now, and later on discuss about
DispatcherTimer in WPF.чудесная статья про программирование. добрая.
What a programmer does for a living
What a programmer does for a living is best illustrated by writing a program yourself.
So, today, you'll write your first program!
"But I don't know how to!"
Don't worry, you'll manage, it is not all that hard. The program is going to be in a language called "English".

I searched high and wide for something simple to do this and every function I found basically reinvented the wheel from scratch. If you do any amount of searching, you can find the
JavaScriptSerializer object which will convert objects to JSON. Sounds easy enough...WRONG! Even converting an empty DataSet will return a circular reference exception.overloads
In the MS doc "New features in C# 4.0" there is this example
of applying "Betterness rules" to overload resolution...
Given these overloads of M..
M(string s, int i = 1);
M(object o);
M(int i, string s = “Hello”);
M(int i);
which does M(5) use?
Given these overloads, we can see the working of the betterness rules. M(string,int) is not applicable because 5 doesn’t convert to string. M(int,string) is applicable because its second parameter is optional, and so, obviously are M(object) and M(int).
M(int,string) and M(int) are both better than M(object) because the conversion from 5 to int is better than the conversion from 5 to object.
Finally M(int) is better than M(int,string) because no optional arguments are omitted.
Thus the method that gets called is M(int).
Ok, clear enough for this example...but I hope I don't have to debug code
that uses this feature a lot!

мониторинг веб-сайта
A simple and free website surveillance utility implemented in VBScript. Configured as a scheduled task, one or more URLs can be monitored for availability and content can be checked. When a site or URL is down, or if the content returned (or a specified fragment of it) does not match the last returned content, an alert email is sent to a specified email address.
