azureI recently needed to verify the integrity of a large number of XML files that are stored in Azure Blob Storage. These files were essentially hand-written and contained numerous typos, errors and other inconsistencies. I needed to not only identify files that contained well-formed XML, but also find files containing nodes with names that were not on a list of known good names.

visualstudio-wallpaper-05At one point I was coding on a hobby project, using Visual Studio Online for project management and source control. Because of the technologies involved, a large number of temporary files were being generated that I didn’t want checked in. Visual Studio’s TFS integration is pretty good at automatically filtering these kinds of files out and placing them in the Excluded Changes list in the Pending Changes window, but in my case the sheer number made it a pain to scan the Excluded Changes list for valid changes that I actually wanted to commit.

In my case, I didn’t want those temporary files to show up at all – not even in the Excluded Changes list. In order to gain control over which files TFS should ignore completely, I added .tfignore files to my solution. These allow you to specify which files, extensions and directories to ignore (or un-ignore!) from source control. If you’re familiar with the concept of .gitignore files in GIT, you should feel right at home.

I recently encountered a requirement to programmatically zip multiple files into an archive in a Windows 8 JavaScript/HTML app. The intent was to shrink the several large files as much as possible for eventual submission to a central server. This operation needed to occur without the user’s direct involvement as part of a larger data transmission process.

While the Windows.Storage.Compression namespace does provide an interface for compressing individual files, there is no native support for creating a multi-file archive. In order to implement this feature I chose to use the third-party JSZip library, which is a light wrapper around the zLib library. Read More…
