See the original posting on JavaWorld

The newly-announced Echo Show is available for pre-order in black or white and the shipping date is finally right around the corner: Wednesday, June 28. If you’re interested, there are two things you need to know. Right now if you buy two of them and enter the code SHOW2PACK at checkout, you’ll activate a $100 discount. So you’ll get two new Echo Shows for the price of two standard Echos. Go in on this deal with a friend, or buy a few for yourself (they work very well in multiple rooms). The other thing you should know is that by selecting Prime 2-day shipping, Amazon will actually have the Echo Show on your doorstep the very day it’s released. Echo Show brings you everything you love about Alexa, and now she can show you things. Amazon has announced an integration with some of the big names in wireless security cams, so you can simply say “Alexa, show me the front door camera”. Echo Show should make a good kitchen assistant as well — just ask for a recipe. You can watch news briefings, YouTube videos, ask for a weather forecast, video chat with family and friends (if they have Echos as well), see music lyrics, photos, to-do and shopping lists, and more.  All hands-free—just ask. New skills and features are added all the time.  See this deal now on Amazon.

CheerpJ converts Java apps into JavaScript for the web

See the original posting on JavaWorld

Melding Java and web development, CheerpJ is being readied as compiler technology that takes Java bytecode and turns it into JavaScript, for execution in browsers. Based on the LLVM/Clang compiler platform as well as Learning Technologies’ own Cheerp C++-to-JavaScript compiler, CheerpJ takes Java bytecode and turns it into JavaScript without needing the Java source.

In CheerpJ, applications and Java libraries are converted to web applications, so there is no need for plug-ins or Java installations. Server-side Java components can become client-side browser-based libraries while native Java code serves as platform-independent components for the Node.js server-side JavaScript platform.

See the original posting on JavaWorld

“The right tool for the right job.” If such wisdom holds true anywhere, it certainly holds true with the choice of database a developer picks for a given application. Document databases, one of the family of data products collectively referred to as “NoSQL,” are for developers who want to focus on their application rather than the database technology.
