Last weekend I found some time again, to compete with a blog. Like the previously decided, that reduce the amount of unnecessary English language on the page. This time we went to plug wallpaper OpenID. It is used to enable logging system using OpenID. This allows users to log on to several blogs using the same password.

In the course of writing the code is already accustomed to this, that you should write tests in parallel. Approaches, when and how to write tests is much.

Increasingly, the projects begin to use LINQ and begin to see advantages. Not only, that in this way can write some code, and gain some clarity.

This knowledge is needed, example, if you add a file to a directory with the program already installed. The simplest example is to write different kinds of plugins. The problem does not occur if the application has been installed in the default directory, we know, but this can no longer guarantee. […]
Would seem, that such an act as to define a static IP address on the basis of number of MAC in the XXI century should not cause any problems. Until recently, I thought, that the market will not find router, that does not have such functionality, and here recently I had to do such a thing in LiveBox. Going through the standard menu, I have not found any function, which would allow it. As is usual in this type of problems I reached for Google. And yes there were many solutions, but most of them were based on the telnet [...]

I’ve been on it in October and now in January, going again in August. And besides, they look … […]
Today I needed to do a very unusual operation - reset the index in the table in MS SQL. I honestly did not think, that makes it so easy to. To do this, use the command: DBCC CHECKIDENT (nazwa_tabeli, reseed, ostatni_indeks) In the command, give the name of the table, where we want to reset the index and the number of the last index in the table. If you want to automatically generate numbers that began with the 1 it must use this command in the following manner: DBCC CHECKIDENT (nazwa_tabeli, reseed, 0) It should be remembered, that [...]
