I want to add a program writtem by me to the Yocto and make it part of the build through core-image-minimal. How do I do this? I really couldn't get much info from the reference manuals regarding this.
Can anyone point me to the link where I can get a step-by-step procedure to add a user defined program?

You can try this open-source library to talk with the FTDI: https://github.com/lipro/libftdi
Download and unzip it and then just follow the procedure on the README.
Once you finish it, if you are on build you can:
cd examples
make
Now you just load your examples on the terminal like using './'
You can also modify as you want and then remake those examples.

Class 'kartik\base\InputWidget' not found

In my Yii2 apps I add extension select2, since composer not successfully downloaded all the needed librarys. So I do it manually but I have still have error. Any help is BIG THANKS.
Here is my error.
I think since you did it manually you
forgot to add this file: input widget file
or did not specify proper path to it.
Check these and come back if any issues prevail.And always try to use composer as it's better to solve composer errors than finding what is missing after doing the entire set up.Isn't it? ;)

Using UnitySteer's SteerForPath in Unity3D

I tried asking this question on Unity Answers, but I don't seem to be getting an answer there, so I thought I'd try here
I'm trying to use the SteerForPath script in UnitySteer 2.5 with AngryAnt's Path 2.0 for a racing game, but I'm not sure how to: I can set up the waypoints in Path, but the SteerForPath script doesn't provide a way for a path to be linked to it in the inspector. Can anyone help me with how to link a waypoint path to UnitySteer's SteerForPath? It doesn't have to be AngryAnt's Path, but if it isn't it would be helpful if you could provide a tutorial or demo as to how to set up a waypoint path in that other system.
Thanks.
Are you referring to SteerForPath.cs in the Steering package from Arges-Systems? If so, you're better off using SteerForPathSimplified.cs
This version has a publicly available property for assigning a 'Path'. Though the Arges-Systems author does state (halfway down in comments) that his SteerForPathSimplified.cs is not necessarily designed to work with AngryAnt's code, but you should be able to quickly modify it to suit your needs.

How do I use the Groups.pm in Request Tracker?

In lib\RT\CustomFieldValues\ there is the groups.pm file which is supposed to be an example of how to get data into a custom field, but how do I actually use that once I have written it? Does anyone have any documentation or a sample of this?
I have finally figured it out, to use the Groups.pm module you need to go to /opt/rt3/etc and edit the RT_SiteConfig.pm and add the line
Set(#CustomFieldValuesSources, "RT::CustomFieldValues::Groups");
Restart Apache and it will be available as a new field source.
I have written a blog post on doing this which also includes details on how to build your own module in case anyone is interested in doing this: AD Lookup Control in Request Tracker
