If for some reason you don’t want to be anesthetized you can just ask. It is also cheaper this way and you can drive yourself home.
Based on my limited research it seems like anesthesia is mostly there because people are prude.
The painful parts of procedure doesn’t hurt any more than having bad gas pain.
And it’s only a few less-than-ten-second points during the procedure that are anywhere near what I would describe as painful.
The insertion of the camera is rather jarring if you’re not used to having things stuck up your ass, but again surprisingly painless.
I was able to watch along with the doctor on a massive tv screen and see my own innards.
Worst part was taking preparatory laxatives before.
Overall not a bad experience for the piece of mind it provided.
Get a colonoscopy if you are due or have reason to believe you should get one.
Not sure what you mean specifically by "need" in "need ... to do compositing". Compositing is just a way (e.g. rerender only on changes, cache results) of running a desktop environment. Strictly speaking you don't need compositing, you can just use immediate mode across the DE and apps.
The tradeoff of course is that if an app is lagging you get a blank rectangle instead of a frozen picture. Well not quite 0 or 1. You can cache lowres and/or compressed frozen picture periodically to improve UX.
I have an ancient laptop from 2008 with 4GB of ram that runs a modern KDE desktop and related applications just fine that I use for troubleshooting stuff. However, the moment I open a web browser it basically falls to pieces.
I hate everything about this. :-/
There is bloat everywhere.
Kind of like fizzbuzz, just something really simple and most basic to get rid of the "easy scams" and so on.
Edit: So "easy scams" are probably the wrong word, I initially wrote "riffraff" because in my mothertoungue that isn't so... disparaging, but what I meant was that it's used as "bare minimum filter" basically.
Done.
But the reality is that he still has significant public support, from a public who get most of their current events from filtered, biased news media. In that way, we've actually become remarkably similar to Russia under Putin.
