You cannot be guaranteed mobile phone reception inside the tunnel. Coverage is typically done using a leaky feeder, relying on base stations on either end of the tunnel.
- The initial requirement was for at least of 50% of radio listening to be DAB before January 1st, 2015. This requirement was changed in 2011 to "digital listening", including streaming radio over Internet and DVB-T in the statistic. The actual percentage for listening over DAB is not published individually.
- 25% of new cars sold do not support DAB. Cars in Norway have an average lifespan of 10.5 years.
- The majority of road tunnels do not support DAB, and will not support DAB before the FM network is switched off.
This last point means using radio to contact drivers in case of emergency won't be possible at all, because:
1. The 20% of cars using DAB will not be able to receive anything while inside the tunnel.
2. The 80% of cars not using DAB won't have their radio switched on, as there is no reception.
That means both that either both of us are weirdos, or a substantial part of Evernote's user base are in line with these concerns.
1. It obfuscates the code for very little benefit. Readability suffers more than performance gains.
The JVM could employ similar tricks under the covers for performance reasons if it detects that this is on the hot path.
2. The code is sensitive to overflow, sign handling, Not-a-Number, and divide-by-zero.
Both these points should be raised by an experienced programmer.
These are two options for who Michael Murphy is:
