Go has first class Unicode support. What do upper-case and lower-case mean when there is no such thing for the character? Does it fail with an error or not? How do you compare the size or length of Unicode characters? 

fmt.Println("? Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo ")

? Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo

Fix For When Bash Can’t Find Its Debugger On macOS

Sometimes Bash needs its debugger but it can’t find it. It looks like this: 

/usr/share/bashdb/bashdb-main.inc: No such file or directory
-bash: warning: cannot start debugger

For example when you start bashdb yourself with bash --debugger or set shopt -s extdebug. Another example is when your terminal turns it on.

Here is the fix that worked on my box:

brew install bashdb
bashhome=$(brew –prefix bash)
bdbhome=$(brew –prefix bashdb)
ln -s $bdbhome/share/bashdb $bashhome/share/bashdb
unset bashhome
unset bdbhome
