Why use a VPN?
Quoting:
"Most of us understand that we should use an antivirus utility to protect against ransomware and the other malicious tools used by hackers and scammers. But less well known is the humble virtual private network, or VPN. These services keep your Web traffic safe from scammers, hackers, and government snoops. If you ever use an unsecured public Wi-Fi network, this is an essential tool."

5 man-year to optimize strings?

The always insightful Java Performance Tuning newsletter has one interesting piece on Java strings:
http://www.javaperformancetuning.com/news/news185.shtml


"For JDK 9, Oracle has targeted improving String in this way. Analysis
of String indicates that most Strings are ascii, so Oracle have changed
String to use a byte array instead of a char array. To make this work
efficiently without impacting String performance across all it's uses,
took 5 man years to achieve. In the news items, you can find Aleksey
Shipilev's fascinating talk about exactly why it took so much effort."
