It’s about asking, “how does this algorithm behave when the number of elements
is significantly large compared to when the number of elements is orders of
magnitude larger?” Big O notation is useless for smaller sets of data. Sometimes
it’s worse than useless, it’s misguiding. This is because Big O is only an
estimate of asymptotic behavior. An algorithm that is O(n^2) can be faster than
one that’s O(n log n) for smaller sets of data (which contradicts the table
below) if the O(n log n) algorithm has significant computational overhead and
doesn’t start behaving as estimated by its Big O classification until after that
overhead is consumed. #computerscience Image Alt Text: “A graph of Big O
notation time complexity functions with Number of Elements on the x-axis and
Operations(Time) on the y-axis. Lines on the graph represent Big O functions
which are are overplayed onto color coded regions where colors represent quality
from Excellent to Horrible Functions on the graph:
O(1): constant - Excellent/Best - Green
O(log n): logarithmic - Good/Excellent - Green
O(n): linear time - Fair - Yellow
O(n * log n): log linear - Bad - Orange
O(n^2): quadratic - Horrible - Red
O(n^3): cubic - Horrible (Not shown)
O(2^n): exponential - Horrible - Red
O(n!): factorial - Horrible/Worst - Red”

I gave my best effort to make a post on a Lemmy instance accessible to the visibly impaired, but I don’t know if what I did was effective. Lemmy doesn’t provide for alt text on image posts, so I figured I would put it in the body of the post. It seem that rind.com hasn’t had much activity. Is Lemmy simply not workable for rblind.com’s intended purpose?
On top of that, communities are just slow to grow in general. We ran the Reddit community for five or six years before it really caught on. I suspect Lemmy will have similarly slow growth.
Another issue is that we still don’t have apps for mobile that are as nice as Dystopia. The website is fine, and there are some decent apps out there, but none quite as frictionless. It was the advent of Dystopia and Apollo that really caused /r/blind to take off. With those apps gone, if someone is going to have to use a worse app anyway, why not stick to Reddit? I think for some folks it feels like they have less to relearn that way.
Regardless, we’re here for the duration! I’ve left Reddit entirely, so I use rblind.com daily myself as the replacement. And the things that have lasting power are the things the people running it use themselves.
I think what would really cause us to grow is if things like Guppe Groups ever have to shut down. Blind folks are hugely involved in Mastodon, and we’re already seeing some folks use rblind in similar ways they use Mastodon groups. It does boost everything posted, so it kind of works that way.
