The whole article seems to be about sticky sessions which are needed for the long polling fallback transport option Socket.io uses when websockets can't be used.
Eg. from the article:
"
the WebSocket transport does not have this limitation, since it relies on a single TCP connection for the whole session. Which means that if you disable the HTTP long-polling transport (which is a perfectly valid choice in 2021), you won't need sticky sessions
"
This is really interesting to hear. I am also red-green colorblind (Protanopia) but the difference between the normal and Protanopia images here is very noticeable to me. I can see that red is missing in the Protanopia version.
I definitely have trouble with many shades of some colors, especially if the colors are really small on the screen.
So many Protanopia colorblind filters in games and apps mess up the colors way too much for me, and look worse and less visible than the non-colorblind normal color settings. Definitely interesting to hear about other colorblind users' accessibility issues.
There are so many degrees of colorblindness that accessibility is difficult to cover for all of us. I hope Mozilla and other developers are accounting for common colorblindness and testing with real colorblind people.
I agree about colorblind modes in games. One where I thought it worked really well was Star Wars Battlefront (2015). Instead of adding weird colour filters to everything it used alternate colours (blue and yellow instead of red and green for deuteranopia) in the HUD.
I feel the same. I am clearly red-green colorblind and I can't pass these tests with a lot of circles in different colors, but all the images from this list look very distinctive to me.
I also can't use the red-green colormodes in slack, iOS, mac, etc. because it makes the colors too... weird.
I often wonder if it's because the colors that I see, grew up with and label as "red" and "green" are actually different to what other people see as "red" and "green". But since we all just use these words to describe color, I would never know if the world that I see is similar to what everyone else sees.
Maybe the colorfilters do make things look 'real' and the red that comes out after the filter is the real red like how other people see it. But I'm already too used to "my red" that the "real red" just looks fake and odd.
Exactly my experience. I can see red and I can see green, I just struggle to identify the difference in small steps of red to green. Kind of the opposite of how people with tetrachromacy can see more yellows. Normal people can see yellows just fine, they can't differentiate them as well.
I think these computer compensation controls should be sliders.
Facebook's ErrorUtils have recently been updated to use `window.performance.memory`, which is undefined in Firefox and causing an error to be thrown. This value is defined in Chrome. Looks like this was tested in Chrome but not in Firefox.
