Locate your java home directory by executing in Termal
This will return the full path to your java home directory on your Mac. Change into that directory and then you will be able to run the java keytool from there.
Here is a log of what I ran in Terminal on my Mac:
$ cd /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
Second tank on the car! Here are some of the numbers and calculations to go with the second tanks worth of driving. This time I filled up sooner than I did last time. It looks like I did a bit better this time with driving conservatively.
You can check out the raw numbers on my spreadsheet https://docs.google.com/spreadsheets/d/1HwBsTNKAzO8PoKEtKho5YRi8262yEx5zecYCYuuUct8/edit?usp=sharing
Driving: 779 miles (298 gas + 480 electric)
Gallons of gas: 6.234
Kilowatt hours of electricity: 89
Tank miles per gallon: 47.8
Tank miles per kilowatt hour: 5.39
Total fuel cost: $24.6 = $15.89 gas + $8.71 electric
(6.234g * $2.549/g) + (89kwh * $0.097883/kWh)
Took an average of the 2 rates from our electric company ($.088594 per kWh [first 600 kWh] and $0.107172 [remaining kWh])
Fuel cost per mile: $0.053 gas & $0.018 electric
Combined fuel cost per mile: 3.16 cents
Fuel economy extrapolated out to 100k miles of similar driving: $3,157
($0.0315789473684/mile * 100,000 miles)
When you have video or audio that is not playing back correctly, it can be helpful to check out chrome://media-internals/ which is documented at https://www.chromium.org/audio-video/media-internals
This can give you some information on the playback including errors that may have occurred.
Keyframe misalignment can cause stuttering when switching between renditions. To check for this you can use a tool like aegisub.
