How can I tell if a file is an image of some type?
The perceived type tells you what kind of file it is, for a very general sense of the word "kind".

Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
History is littered with hundreds of conflicts over the future of a community, group, location or business that were "resolved" when one of the parties stepped ahead and destroyed what was there. With the original point of contention destroyed, the debates would fall to the wayside. Archive Team believes that by duplicated condemned data, the conversation and debate can continue, as well as the richness and insight gained by keeping the materials. Our projects have ranged in size from a single volunteer downloading the data to a small-but-critical site, to over 100 volunteers stepping forward to acquire terabytes of user-created data to save for future generations.
The main site for Archive Team is at archiveteam.org and contains up to the date information on various projects, manifestos, plans and walkthroughs.
This collection contains the output of many Archive Team projects, both ongoing and completed. Thanks to the generous providing of disk space by the Internet Archive, multi-terabyte datasets can be made available, as well as in use by the Wayback Machine, providing a path back to lost websites and work.
Our collection has grown to the point of having sub-collections for the type of data we acquire. If you are seeking to browse the contents of these collections, the Wayback Machine is the best first stop. Otherwise, you are free to dig into the stacks to see what you may find.
The Archive Team Panic Downloads are full pulldowns of currently extant websites, meant to serve as emergency backups for needed sites that are in danger of closing, or which will be missed dearly if suddenly lost due to hard drive crashes or server failures.

A customer was debugging some code that calls on a class that's already been registered. In this case, it was registered by another DLL in the same process. Normally, this wouldn't be a problem, because each DLL passes its own instance handle to so that there are no name collisions. However, in this case, both DLLs are passing the flag, which m...
We saw some time ago that permission to delete a file is granted either File attributes behave in an analogous way. Permission to read a file's attributes is granted either If you want the file's attributes, you could always get it by reading the directory, because one of the pieces of information you get from is the file attributes. There...

COM methods cannot be variadic. Why not? Answer: Because the marshaler doesn't know when to stop. Suppose variadic COM methods were possible. And then you wrote this code: How would COM know how to marshal this function call? In other words, suppose that is a pointer to a proxy that refers to an object in another process. The COM marshaler...
