Not colorblind myself, but I often use spectrum as a final pass to make sure any colors I've chosen for a UI aren't going to cause issues. I just hope it's decently accurate.
I'm also a very heavy F.lux user, so all my color choices have to be usable with an orange filter as well.
I have implemented MACsec on Juniper devices for many clients. It's great to see it finally supported in Linux. It would be great to see more vendors supporting it.
In my efforts to be as vendor agnostic and possible, and as open minded towards solutions for my clients, it's always great to see multiple ways to deploy something this complex.
If I'd decided to sell out of my collection instead of giving it away, I'd have had some parallel cases - any large enough collection is liable to include a small but significant proportion of one-off parts. I'm not sure a 2x4 black brick is likely enough to sell that it'd be worth listing alone, but I suppose someone with a sufficiently completist bent might go to the trouble.
