Lightweight Browser

Folderol · 2020-08-13T09:32:40+00:00

Can anyone recommend a browser with as little overhead as possible, and reasonably performant - doesn't have to have all the bells and whistles. I'm running devuan beowulf - not easy to set up initially, but much leaner than raspbian. -- W J G

Yeah, I'm more focused on keeping it in range than exactly matching the user's input. If they think results seem odd, turn on the verbose mode and see what happened.

I rarely use getopt(), and usually go for getopt_long(), but I'm not expert in either. I skipped getopt_long() here because I believe getopt() is a lot more portable. I seem to recall I needed to #ifdef some include files on one of the BSDs last time I tried it.

I'll probably make a proper repo, and include animations, sometime this weekend. I'll look into testing more edge cases then.

Might be worth having a look at replacing usleep with nanosleep, since the former is deprecated. Not sure if some platforms already omit it, but I guess not; that would break too much. It probably overshoots by quite a lot, though, which is another reason why nanosleep might be preferred. (And/or why you might need a time diff as argument to the sleep function, instead a fixed value.)

Always check how long your sub-second sleeps are actually taking. Some implementations return immediately if the wait is less one timer tick, others always wait at least one timer tick, however long that is on the particular platform.

I was always pulling up the other engineers for using Python usleep's of less than 1ms (the minimum tick on Windows) which weren't doing anything on Python 2. When we moved to Python3 they suddenly started taking 1ms, slowing down loops far too much.

Run a browser (in a secure sandboxed container?) on another machine (another Pi?), and do an Xsession connect to it. Obviously won't be great for video, but it shouldn't load your main desktop down.

Not really an option unfortunately. The idea is for this to be completely stand-alone.
