From the introductory first part of the Akka Notes, we saw a bird's eye view of Actors in the Akka Toolkit. In this second part of the Akka Notes, we'll look at the messaging part of Actors. As for the example, we would use the same Student-Teacher example that we discussed earlier.
Make sure you didn't miss anything with this list of the Best of the Week in the IoT Zone. This week's best include 17 wearables killed by the Apple Watch, an Arduino prototype to track sleeping habits, the release of the Edison development platform for IoT, and more.
Security in the Internet of Things is a fairly common concern these days - you know, Heartbleed, toasters, that kind of thing - but you may not even have considered the greatest threat to your connected devices: classic 1990s first person shooters.
What are the domains in the Internet of Things landscape? And which ones are developers and IT professionals most interested in? See each IoT domain's interest ranking and the percentage of developers who have actually worked on applications in those domains.
IoT and Big Data provide an opportunity, even if not new, to gather information and make executive decisions much faster than before. Football, as with other sports, is very competitive, IoT devices are getting cheaper, and more data can be collected for analysis than ever before.
In this post we are going to explore how to enable Java security manager for WSO2 products. For this we need to sign all the JARs using the jarsigner program. For learning purposes, I will use the wso2carbon.jks Java key store file, which ships default with WSO2 products.
You've probably heard about Android Wear by now, but how does one transition from traditional mobile Android development to Android Wear? One option that makes a lot of sense is to work with existing Android apps that you've already developed.
Anyone who has done multithreading in the past won't deny how hard and painful it is to manage multithreaded applications.
If you're new to IoT, or just trying to get a more detailed sense of what's going on in the space in terms of IoT products and use cases, you might be interested in How to IoT Your Life: The Complete Shopping List, which first appeared in DZone's 2014 Guide to Internet of Things.
In my earlier post, I was running into the ‘single camera’ trap of the current RIoT Android OS image: with only one camera attached, and switching between front/back camera, Android is stuck and needs to be flashed again to the board.
My 2 1/2 year old son wakes up before us during the spring and summer. He turns his light on fully, and plays until he's bored. The problem was: exactly when was he waking, because it would affect how tired he was in the day (and affect nap times). So I built a tiny Arduino prototype :-)
Make sure you didn't miss anything with this list of the Best of the Week in the IoT Zone. This week's best include a look at Hackstock for #LocalGov, the introduction to the Apple Watch, how to build smart things with AllJoyn and Kii, and more.
Many times I start with a project and tutorial, only to get interrupted. For a long time I wanted to add GPS (Global Positioning System) functionality to one of my projects. While I started a few months ago on this, it took me until this week-end to finish at least the first part: an SD card data logger with GPS.
If you've been looking forward to Intel's Edison development platform since it was announced, your time has come. At the IDF 2014 keynote a few days ago, Edison was released. Intel has brought us IoT.
Now that Apple finally threw its hat into the smart watch and fitness band arena, here are the inevitable casualties in the same category that will probably be crushed under the weight of Apple brand superiority, if not technical superiority.
It's a familiar trend when it comes to hackathons - to startup-centric software development in general, maybe - that the app comes first, and the reason comes second. Hackstock for #LocalGov, on the other hand, is an interesting twist on this tradition.
If you missed anything on DZone this week, now's your chance to catch up! This week's best include the reasons why Vaadin is a Passat, named parameters in Java, mobile gaming with Haskell and SDL, NoSQL job trends, and more.
When I ordered my first Freedom FRDM-KL25Z board, I placed an order the Tower TWR-KL25Z48M shortly afterwards. The good news is that at least for the USB applications, my USB demo projects on GitHub for FRDM-KL25Z work 1-to-1 with the Tower board too.
The iPhone 6 wasn't the only thing to come from the Apple Event - also, the Apple Watch. Here's what we know so far.
When I showed my 60 NeoPixel LED clock prototype to my daughter and her girlfriend, and they both wanted to have one right away :-). Well, that clock was just a proof of concept, with lots of temporary wiring. So I decided this week-end to beautify it and to make it look nice and clean(er).
In the past year, IoT events and IoT meetup groups have been created all over the world. A lot of the Meetup groups, including the one I attend in Ottawa, have great content and networking opportunities. Similarly, there is a wealth of IoT events that you can attend throughout the year.
Before I can run my application code, the microcontroller needs to be initialized properly. Basically this means configuring the pin muxing and clock gates. As this is usually depending on the board or what is attached to the pins, this is named ‘board configuration’ too.
There has been an SDK for the Pebble since it came out, allowing developers to create watch faces and apps with C. You can read more about that on their developer guide site. Recently though an alternative way to develop for Pebble was released - PebbleJS.
I am thrilled to announce the Eclipse Board of Directors has formally approved the creation of the Eclipse IoT top-level project. This is an important milestone for our vision of creating an open source community that is creating the technology to power the Internet of Things (IoT).
