DietPi is the perfect OS with easy install software for Pis of all flavours.
That's not how the two entries for DNS works. Devices will use both rather randomly, and therefore some requests will not be filtered.
The best way is to run two instances for redundancy.
Yeah, Odeon is pretty rubbish. At least Cineworld have their unlimited pass (do they still do that?) and Vue have their cheap tickets.. Odeon's are just sticky-floored stuck-in-the-80s, unhappy-staff hell-holes :(
They're the first 4/5 rows, the back row, and sometime a weird block off to the side which is above the entrance (I don't know why those exist). But considering the row behind is the VIP seating - the back of the 4/5 group is pretty close to the best row but half the price.
And £5.99 outside of London (if bought online and in "Super Saver" seats). Gawd Bless Vue.
Which phone?
Comments are ok, but I think if kbin has microblog posts from Mastodon, they don't appear in Lemmy. I'm in two minds as to which interface I prefer - nows really the time to pick one before I subscribe to too many things! :)
You can take the community and server name and format it like this: https://lemmy.world/c/TheyDidTheMath@kbin.social
But kbin is more than just posts - it also federates Mastadon which I don't think Lemmy can process (so you won't see those).
(I'm still working all this out myself -- in fact, this is my first ever comment!)
Run two and check the logs. You'll see about 20% of your requests will log on the second instance. So currently, that's 20% of your DNS requests not being filtered.
You'll also find some devices just latch on the the second and never use the first - again, in your scenario, these are not being filtered.
