Nearly all the images you’ll encounter on your day to day browsing otoh is tiny and heavily compressed, bigger than text, but not enough to have a notable impact like video can.
I’ve noticed that people are quite bad at choosing the right compression algo for the job. And Wired mag concurs. SVG should be favored, but JPEG, PNG and GIF dominate. And even if you don’t have a vector graphic to start with, people often make the wrong choice between the three.
“reducing emissions can also be as simple as limiting the number of images that feature on each web page.”
-- Wired
“Images are the single largest contributors to page weight. The more images you use and the larger those image files, the more data needs to be transferred and the more energy is required,”
-- Vineeta Greenwood, account director at design agency Wholegrain Digital
edit: I just realized this is another problem Cloudflare brings us. When web admins opt to offload their job onto Cloudflare, they have less incentive to ensure their website is lean. The Wired article says web pages have quadrupled in weight since 2010. I’m sure much of that can be attributed to Cloudflare facilitating the bloat.
As far as reverse tethering, it’s under USB “internet” in settings
So you navigate this way: settings » USB internet? (my ~6+ y.o. device does not have USB anything in the top level)
Is the reverse tethering switch in a different place than the forwards tethering switch in your case? I found this well-written guide by someone who favors configs over software for this. Unfortunately the article has no date but it was archived in Oct.2020. He says root is required as well as terminal commands, but since it was possible with root for a long time I assume you’re saying recent versions make the option available without root. The article mentions this path:
and that’s what I have. There is a “USB tethering” boolean in the Tethering & portable hotspot page. I have always figured that option was strictly for forward tethering. And to reinforce that assumption, when Gnirehtet is running that “USB tethering” switch is in the off position (but perhaps because it uses the phony vpn approach). The article seems to be using that boolean for reverse tethering, unlike Gnirehtet.
