Remember Kids, IE Security Settings Affect Firefox Too

I was configuring a new Windows Server VM yesterday, and the first thing I do on a blank Windows server is launch IE once and once only to download Firefox. To avoid what I call the "trusted site dance" with Mozilla's mirrors since IE doesn't let you add a trusted site and then continue the download you started, I go into IE security settings and make the following setting changes to the Internet zone:
  • Enable file downloads
  • "Prompt" for launching applications and unsafe files
  • "Prompt" for launching programs and files in an IFRAME
Note that these are the settings you need to change if you get the "Your current security settings do not allow this file to be downloaded" error.

This time I decided to be a good boy and change these settings back to disabled after I was done, and then I launched Firefox to download Java and some other things I need to install on this server. This probably shouldn't have surprised me, but when I tried to download anything in Firefox, it would download a 0 byte file and the download dialog box would read "Canceled."

I went back into IE's security options and re-enabled file downloads and voila, I could download files again.

I understand the fact that IE's security settings tab is really a shortcut for Internet Options at the OS level, but this is still pretty irritating. What if I want file downloads disabled for IE but enabled for Firefox? Guess you can't do that. Thanks Windows.

I use the solution you posted a few months ago. I prefer to manage Firefox settings in Firefox, not IE.http://blog.mattwoodward.com/bypassing-windows-security-checks-in-firefox

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.

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 …

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:
<dpiAware>True/PM</dpiAware>
Which I changed to this: <dpiAware>False/PM</dpiAware>
Note that you'll probably have to edit the file as administr…
