Comment: 100% on Ishihara (Score 1) 267

I do Ishihara every time I renew my aviation medical certificate.

To respect the spirit of the test I make a point of not memorizing the numbers, and always call the number at a glance.

Some years ago I had a colleague who chose such odd colour combinations for her clothes we wondered if she had issues in this area. This is indeed unusual in a woman, but it happens.

I'm nearsighted and have worn glasses on and off since I was about 10. I wore contacts through most of my 20s, but returned to glasses in my 30s.

Now that I'm in my 50s I'm in that stage where my near vision is starting to deteriorate and I'm slowly becoming far-sighted. The first real manifestation of this was when flying at night, when I was experiencing massive eyestrain reading charts in my lap, but could see outside the plane just fine. So I got progressives the last time I got new glasses, and I'm fine.

I don't wear glasses when I'm not driving or flying. I prefer a soft-focus world. :-)

Am I a candidate for laser eye surgery? According to the web sites, not really. I could get good distant correction, but would then need glasses for reading. Since I need glasses to drive and to fly anyway, I'm not sure this would buy me anything.

Comment: Too secure == insecure (Score 1) 280

The problem with crazily-complex passwords is that if you can't remember them you write them down, and, at a stroke, have compromised security. One of the worst I've encountered is the U.S. Customs eAPIS web site, for sending advance information when you want to fly a private plane or sail a private boat to the U.S.

The other issue is that you risk locking out legitimate access.

My bank does the password plus security question thing. My security questions (you can make up your own) are more than a little interesting. :-)

This was an educational experience for me, learning the difference between colour temperature, which is really only valid for continuum sources, and colour rendering index, more applicable to spectral line sources. Low CRIs don't necessarily have a low colour temperature, but they definitely distort perceived colour, whether they're too blue, or the weird orange of sodium vapour lights.

The most stringent CRI requirement in my home is my makeup mirror. Which is the last incandescent bulb...
