It was admittedly harsh and over-the-top... I guess it was just one not-thought-out post too many and I sorta snapped. It may be due to my volunteer work where I comb the blog comments on a popular site for SPAM. That has really exposed me to endless streams of inanity and lowered my tolerance. No excuse, just stating a possible cause of my outburst. I've also taken some time away from the internet, just returned in fact
To the OP. My apologies.
If you are looking for Ubuntu Touch on a Galaxy Tab 3, I don't know of anyone making a port attempt. Here is the list of devices trying out Ubuntu Touch: https://wiki.ubuntu.com/Touch/Devices
Note that most community efforts are not up to date and your device doesn't appear on the list. You could try the Tab 3 Forums and see if anyone is making a port.
If you are looking for Ubuntu Desktop on a Galaxy Tab 3, that is another type of project. Canonical no longer supports it, but it is still feasible to follow the instruction set. Look for various guides and how-tos by searching the internet for "Ubuntu on Android" or "Ubuntu for Android." There are several methods for you to choose from. Ignore Ubuntu for Devices and Ubuntu Touch results as those are for the mobile version.
If you are looking to mod a different device, I really have no clue what that is and you would need to post which device.
