I live in a condo (40ish yo) and recently a neighbor in an adjacent building had a leak and the board suggested that everyone have a plumber come inspect their units. I just inspected and found various levels of corrosion at most joints with the included photo the worst looking of the bunch.

How concerning does this appear?

Is anyone else having an issue of the back button being greyed out after clicking a link?

I will do a google search, click on a site, then I have to redo the search as I can't go back? It may be happening on other sites, but I am especially noticing it after google searches.

If you have, how well has it helped? Did different colors, such as those driving yellow tinted ones, help more? I have some transitions glasses, but that only helps outside. I saw on at least one site rose colored migraine glasses and am thinking about getting a pair.

I am new to sdr. Currently I have an rlt-sdr dongle running rtl_fm piped to ffmpeg. I’d like to switch to something that I can change the frequency without shutting it down and can be run as a daemon on linux, ie no tui or gui. I am having difficulty finding anything currently available.

Is there anything out there or is my only choice to modify rtl_fm to do what I am wanting?
