So, when I got home yesterday, I found that my Samsung microwave was beeping frequently for no apparent reason. Switching it off and back on did fuck all and occasionally I'd see the clock display read "5E" or "SE". This issue didn't go away even after a few hours and I'd resigned myself to having to go through the rigmarole of calling a service center and getting this fixed which would undoubtedly involve charges amounting to a good chunk of the microwave's original price. Of course, that wasn't what I did.
I wanted to update my old tablet, a Samsung Tab 2, to a more recent version of Cyanogenmod as it was beginning to act up a little. But now that Cyanogenmod is officially dead, the new overlord of Android ROMs is Lineage OS and that's what I installed. All went well and the tablet, now running Marshmallow, was stable and running smoothly. However, there were a couple of glitches.
