Doug from Beaumont, CA

Doug likes to visit the Aviation Weather Service online, but he's been having trouble with it lately. Leo says that's because it uses Java and the Java browser plugin has probably been disabled. Doug should go into his browser settings and be sure it's installed, updated, and enabled. But it's getting harder to use Java in the browser. If he has Firefox version 52 or higher, or Chrome 42 or higher, or even Safari, the plugin would have been disabled for security reasons. So his only choice may be to use Internet Explorer for that site. He'll have to turn on scripting for Java apps.

Kristi from Apple Valley, CA

Kristi is having trouble with Firefox loading. Leo says it's likely a problem with an extension. She should start up Firefox without the extensions, and it's likely it'll start right up.

George from California

George wants to know if he should update his Java? Is it OK to update?

It's definitely safer security wise to do so. But Jason also recommends getting rid of Java altogether. When in doubt, though, always go directly to Oracle to get updates. That way he'll know it's always official.

Episode 1288

Oracle is suing Google for 9.3 Billion over the use of Java in the Android operating system. Java was written by Sun Microsystems which had been acquired by Oracle. The claim is that Google borrowed a little too liberally from Java in the Android operating system. Google claims they did clean room development, and merely figured out what Java expected from the software running it, and duplicated the API, or the programming interface. Oracle says their API was copyrighted. The whole computer industry relies on APIs, though, and the ability to use similar interfaces.
