A million monkeys and a million lack tables

Turns out that anything you can think of has already been done.
I was trawling around the internet and found that someone has already created an enclosure out of a Lack table and even created an Instructable for it and it dates back to 2015.


Whilst some of the ideas are the same, mine is different.

I should be so Lack-y

I vent my printer outside and have noticed that my printer was taking a long time to heat the bed during the cold months of the year.

I then installed the Touch UI plugin.

In all fairness, there was a warning that said something to the effect of loading more than Jessie Lite and it would probably not work well.

Sir, Kernel Virtualbox, Yes Sir!

I am still using Korora Linux (and it is great) which is based on Fedora and as such I found the Linux Kernel is updated more frequently than on, say, Linux Mint.
After I upgraded to Korora 22 and I found that my Virtualbox would mysteriously stop working with this dreaded cryptic error being the reason. I could not understand why the kernel driver was suddenly not installed.
