The Creeping Problem # I recently found myself developing a request-response style system, where the lifetime of a request could be interrupted at any moment. For most same process execution, like your average desktop application, this is a concern, but arises more often when dealing with multiple coordinated processes. My case ended up being the latter.
Introduction & Scope # The PCAP-NG file format is used to store network captured data used by great programs like Wireshark. There are several API's available for both Linux and Windows but none that are ported to .NET. I decided to make one for my own use in building a network traffic replay agent.
Introduction # In some cases, you may want to read/write binary data from/to your relational database. This can be a problem when the data set size exceeds the memory address size (eg. 32-bit processes) or the managed large object heap cannot load it all without throwing an OutOfMemoryException. In those cases, you will need to load the data into memory in chunks. Fortunately, the T-SQL syntax supports this operation.
Introduction # Microsoft introduced native image mastering support in Vista, going forward. The library itself is not too complex but the latest version of the image mastering API (IMAPI) has some quirks. This is well documented by Eric Haddan in his article describing how to build an interop file and use it from .NET.
I was tasked recently with writing a parser for TEDS bit stream data. There is an IEEE published paper with an overview of the standard but it doesn't give any examples for implementation. I was finally able to find a paper that gave examples but still had trouble parsing the data. I finally realized there is not only 2 selector bits after the basic TEDS block but selector bits inside the standard template (2 in the case of template 25). Here are my main findings:
