Java Application Server Debate. What type of Java app server should you choose for your next project?

Java Application Server Debate

Well, that kinda depends on what kind of app you’re building, what your needs are, what type of organization you work in, and lots of other factors too. Hence the debate. So perk up your ears, and get ready for a showdown. What makes an application server is a contentious question to many, as the definition is unclear. Wikipedia, the unquestionable source of all knowledge, states: “Java Platform, Enterprise Edition or Java EE (was J2EE) defines the core set of API and features of a Java Application Server.”

Well, sorry Wikipedia, but for the sake of this report, we don’t care about pedantic definitions and full Java EE implementations, we care more about what a developer wants and uses. Most developers work on web applications and rarely use all of the bells and whistles that come with the EE specification. What we’re looking at in this part of the report are the real developer concerns and metrics including: Authors. Controlling a House 50 Miles Away With MQTT and Raspberry Pi.

Reference. Near field communication. A summary of near-field communication Near field communication (NFC) is a set of ideas and technology that enables smartphones and other devices to establish radio communication with each other by touching the devices together or bringing them into proximity to a distance of typically 10 cm (3.9 in) or less.

Near field communication

Early business models such as advertising and industrial applications were not successful, having been overtaken by alternative technologies such as barcodes or UHF tags, but what distinguishes NFC is that devices are often cloud connected. All NFC-enabled smartphones can be provided with dedicated apps including 'ticket' readers as opposed to the traditional dedicated infrastructure that specifies a particular (often proprietary) standard for stock ticket, access control and payment readers.

By contrast all NFC peers can connect to a third party NFC device that acts as a server for any action (or reconfiguration). History[edit] Design[edit] Standards[edit] NFC Protocol stack overview.

Google’s I/O experiment unites sensors, ‘big data,’ and the cloud. Google tricked out its entire I/O conference with hundreds of sensors this week.

Google’s I/O experiment unites sensors, ‘big data,’ and the cloud

Today, we got a glimpse at some of the data and the work that went into making it happen. Michael Manoochehri, with Google’s cloud engineering group, explained the project from Google’s perspective: It’s a big experiment designed to help Google figure out how to use its many cloud tools to collect, organize, and analyze large quantities of sensor-driven data. Google I/O data sensors by the numbers 400: The number of sensor modules (aka “motes”) that have been plugged in around the conference center.525: The number of sensor modules that Google built for this project. To pull off the project, Google needed some hardware-hacking experts. From VentureBeat Location, location, location — Not using geolocation to reach your mobile customers?

The pair designed a sensor module based on the Arduino Leonardo R3 chip, a popular microprocessor that many DIY hobbyists use. Did they learn anything about the conference?
