CronPlugin for OpenBD




From OpenBD

Category:CronPlugin



The CronPlugin makes the management and scheduling of tasks much easier within OpenBD.

Inspired from the simplicity of the /etc/cron.d/ subdirectories, this plugin brings the ease of that method to the CFML developer by allowing them to simply drop files into pre-defined folders that will be automatically run, without needing to wrestle with external scheduling jobs or CFSCHEDULE.

The plugin will automatically create the necessary directories if they do not already exist. You set this directory by making a call to CronSetDirectory(). This directory location will persist over server restarts.


For example making a call with:

CronSetDirectory("/cron.d")


will create the following directory structure within the web app directory.

/<webapp>/
/<webapp>/cron.d/cron.5min/
/cron.15min/
/cron.hourly/
/cron.daily/
/cron.weekly/
/cron.monthly/



After this, you can simply drop .cfm files into each of these directories and they will be run at the allocated time. There is no need to restart the engine, or re-call the CronSetDirectory(); it will automatically be picked up.

Everytime the plugin executes one of these files at the desired time, a copy of the output is retained. Within the OpenBD working directory, a similiar structure is created but under the plugin-cron directory, where you can view the results of each file.

This plugin triggers the main OpenBD CFML engine directly, without having to go out and back in via HTTP. This makes it highly efficient and removes a lot of the overhead associated with other schedule methods.

This plugin operates with the nightly build post 4th March 2010 and can be installed by simply copying the .jar file into the /WEB-INF/lib/ folder of your web app.

Another awesome plugin for OpenBD. Some really slick possibilities here, and my favorite thing is that FINALLY we have a way to run scheduled tasks without them simply being a scheduled HTTP call. The CronPlugin processing the CFML code in the engine directly.

Note that this doesn't replace the traditional scheduling, but it's another option that will work really well for a lot of use cases.

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…
