Time sync and Windows

I’d always believed that the only requirement for synchronizing time on Windows machines is the NET TIME. This command allows clients to sychronize their clocks with a domain controller (DC) and the server version has a command line option to allow an external time server to be specified. Certainly the domain’s clients sychronize their clocks […]

His example is great because it provides an extension method to chop any IEnumerable (for example a file stream) into chunks which are to be processed independently. In […]

I think the whole link thing is great (see earlier post) but is constrained to to dealing with flat data. Sure you can group but if you need groups nested three deep then you have to know this in advance. Hierarchical structures […]
