<@macdjord>
I think the space bar on my new laptop has a debouncing problem
01:09
<&[R]>
"Debouncing"?
01:09
< Mahal>
"re-upping itself after being pressed down"
01:09
< Mahal>
I think
01:10
< Mahal>
usually meaning "it's not bouncing properly" so you end up with multiples of a keypress
01:12
<&[R]>
See, I'd assume that "bouncing" would indicate that it "bounces" back up
01:12
<&ToxicFrog>
Mahal, [R]: in some types of switches, there is a "bounce" effect when the switch closes, causing the contacts to meet, then bounce off, then meet again, possibly several times.
01:13
<&ToxicFrog>
So electrically, it's not open->closed, it's open->closed->open->closed->open->closed over the course of a few ns or ms
01:13
<&ToxicFrog>
Thus, for digital applications, there is usually a "debouncing circuit" applied (either in hardware or in software) to make it look like a nice clean rising edge.
01:14
<&ToxicFrog>
If the debouncing circuit is malfunctioning, one keystroke in hardware ends up registering as multiple rapid keystrokes in software as every bounce registers as a separate keypress.
01:14
<&[R]>
Ah
01:15
<&[R]>
TIL
01:16
<@macdjord>
[R]: I hit it once, but it acts like I hit it twice.
01:17
<&[R]>
Fair enough

Oh hey, the wikipedia page has a graph: https://en.wikipedia.org/wiki/Switch#Contact_bounce

I lack someone above me
17:58
< Jessikat>
There's many areas I could use someone in though
18:00
<&jeroud>
Doesn't have to be someone above you, just someone with skills or experience you lack.
18:02
< Jessikat>
That's what I mean - above in the sense of the particular area
18:02
<&jeroud>
Ah.
