Open BlueDragon Admin Console Version 1.4 Updates

It's that time again! As many of you know Open BlueDragon is on a regular six-month release cycle, so late October means it's time to certify those great nightly builds as gold, stamp a final version number on it, and immediately get started on the next version.

Along with each new release of OpenBD comes updates to the admin console, which is an open source project of its own, written entirely in CFML. I point that out not only to let you know if there are features you'd like to see in the admin console I'd love to hear about them, and also since it's written in CFML if you want to get involved with the project you're more than welcome!

Version 1.4 of the admin console doesn't have major changes (we have more major revisions planned for the 1.5 release next April), but I managed to squeeze some nice new features in here. See the attached screenshots to get a visual on these.

Application and Session Status Info

The admin console now displays the number of running applications and sessions along with a list of the names of the running applications. In addition, leveraging the new ApplicationRemove() function you can now unload applications from your OpenBD instance with a simple click of a button in the admin console. If you have an OnApplicationEnd() method defined in your Application.cfc this will get called as the application is unloaded.

JVM Memory Information

This was a simple little addition that uses the new SystemMemory() function, allowing you to see JVM memory stats for used memory, free memory, total memory, and max memory. Nothing fancy yet but it at least gives you an idea of what's going on with your memory.

File Cache Statistics

If you've been using OpenBD for a while you're probably familiar with the fact that the file cache hit and miss stats were not shown in the admin console. This is no longer the case. You will now see file cache statistics from the admin console, and can even drill into details about the specifc files in the cache. This leverages the new SystemFileCacheInfo() and SystemFileCacheList() functions.

Slow Query Log

This feature was added to OpenBD a whlle back, but until now you had to modify your bluedragon.xml file to enable it. There is now a checkbox in the admin console that lets you enable slow query logging and specify the number of seconds past which a query will be considered slow and be logged. You can also view the slow query log file in the admin console's log file viewer. The slow query log shows you the time when the query was run, the total execution time in milliseconds, the tag (CFQUERY or CFSTOREDPROC) that executed the query, the file and line number of the query, and the SQL code of the query. Great info to have when you're debugging or troubleshooting.

That and a few bug fixes are what made it into the 1.4 release, and as I said we have plans for a bigger overhaul for 1.5.

Installing and Configuring NextPVR as a Replacement for Windows Media Center

If you follow me on Google+ you'll know I had a recent rant about Windows Media Center, which after running fine for about a year suddenly decided as of January 29 it was done downloading the program guide and by extension was therefore done recording any TV shows.

I'll spare you more ranting and simply say that none of the suggestions I got (which I appreciate!) worked, and rather than spending more time figuring out why, I decided to try something different.

NextPVR is an awesome free (as in beer, not as in freedom unfortunately ...) PVR application for Windows that with a little bit of tweaking handily replaced Windows Media Center. It can even download guide data, which is apparently something WMC no longer feels like doing.

Background I wound up going down this road in a rather circuitous way. My initial goal for the weekend project was to get Raspbmc running on one of my Raspberry Pis. The latest version of XBMC has PVR functionality so I was anxious to try that out as a …

Running a Django Application on Windows Server 2012 with IIS

This is a first for me since under normal circumstances we run all our Django applications on Linux with Nginx, but we're in the process of developing an application for another department and due to the requirements around this project, we'll be handing the code off to them to deploy. They don't have any experience with Linux or web servers other than IIS, so I recently took up the challenge of figuring out how to run Django applications on Windows Server 2012 with IIS.

Based on the dated or complete lack of information around this I'm assuming it's not something that's very common in the wild, so I thought I'd share what I came up with in case others need to do this.

Fixing DPI Scaling Issues in Skype for Business on Windows 10

My setup for my day job these days is a Surface Pro 4 and either an LG 34UC87M-B or a Dell P2715Q monitor, depending on where I'm working. This is a fantastic setup, but some applications have trouble dealing with the high pixel density and don't scale appropriately.
One case in point is Skype for Business. For some reason it scales correctly as I move between the Surface screen and the external monitor when I use the Dell, but on the LG monitor Skype is either massive on the external monitor, or tiny on the Surface screen.
After a big of digging around I came across a solution that worked for me, which is to change a setting in Skype's manifest file (who knew there was one?). On my machine the file is here: C:\Program Files\Microsoft Office\Office16\LYNC.EXE.MANIFEST
And the setting in question is this:
Which I changed to this: <dpiAware>False/PM</dpiAware>
Note that you'll probably have to edit the file as administr…
