The index of all my past little wonders posts can be found here. In the .NET 3 Framework, Microsoft introduced the concept of anonymous types, which provide a way to create a…

• Are long methods always bad?

  - by wobbily_col

  So looking around earlier I noticed some comments about long methods being bad practice. I am not sure I always agree that long methods are bad (and would like opinions from others). For example I have some Django views that do a bit of processing of the objects before sending them to the view, a long method being 350 lines of code. I…

  - by psheriff

One of the problems with reading XML files is when elements or attributes are missing. If you try to read that missing data, then a null value is…

• Allow anonymous upload for Vsftpd?

  - by user15318

  I need a basic FTP server on Linux (CentOS 5.5) without any security measure, since the server and the clients are located on a test LAN, not connected to the rest of the network, which itself uses non-routable IP's behind a NAT firewall with no incoming access to FTP.

• Can't I just use all static methods?

  What's the difference between the two UpdateSubject methods below? I felt using static methods is better if you just want to operate on the entities.

• Do private static methods in C# hurt anything?

  - by fish

  I created a private validation method for a certain validation that happens multiple times in my class (I can't store the validated data for various reasons). Now, ReSharper suggests that the function could be made static. I'm a little reluctant to do so due known problems with static methods. It would be a private…
