YO! This messaging app has a lot more to say for itself, even offline

Mobile World Congress is not the best place to launch a new messaging app: With thousands of tech-savvy visitors in Barcelona, many of them toting multiple connected devices, public wireless and Wi-Fi networks quickly become so saturated that it’s difficult to send a message via Internet, even a brief “Yo,” to a nearby colleague. But that Yo is so last year. The app that could only send one word still sent every message to a central server before bouncing it over to its destination.+ See our full coverage of MWC 2015 + This year showgoers will be able to try out a new Android app, called YO!, that can send text messages, photos and videos over Wi-Fi to other users nearby without any Internet connection whatsoever, making it a true peer-to-peer messaging app. And as long as they’re prepared to disable certain security settings on their phone, they won’t even need to log on to the Play store to get it: Anyone with YO! installed on their phone can share it with other would-be users over Bluetooth.To read this article in full or to leave a comment, please click here

Lenovo brings 64-bit Android to $129 tablet

Tablets running 64-bit Android haven’t been out for long but prices are already set to fall fast.Lenovo’s 8-inch Tab 2 A8 will ship in June starting at $129, with a 64-bit version of Android 5.0 and a 64-bit quad-core processor from MediaTek. It was one of three tablets Lenovo announced ahead of the Mobile World Congress trade show in Barcelona.Sixty-four-bit tablets have a few advantages. They can support more memory and therefore make light work of multimedia-intensive apps such as games, as well as apps that use encryption for security. More 64-bit Android apps are in development, so a 64-bit tablet also provides some future-proofing.To read this article in full or to leave a comment, please click here

Firefox OS coming to US, developed markets in 2016

Firefox OS, the smartphone operating system from Mozilla targeted at low-cost smartphones in emerging markets, is coming to more developed markets.A new project with carriers in the U.S., Japan, South Korea and Spain will see high-spec phones developed for release in 2016. But rather than challenging Android and iOS head on, the project will target something that’s been largely out of fashion in recent years: flip phones and sliders.Andreas Gal, chief technology officer at Mozilla, said some customers like the older form factors but choosing them often means being stuck with an old operating system that has none of the flexibility of a modern smartphone OS.To read this article in full or to leave a comment, please click here

Firefox OS to help Orange boost smartphone use in Africa

Orange is hoping a sub-US$40 bundle of a Firefox OS smartphone with calls, messages and data will help boost smartphone usage in Africa and the Middle East.On the same day that Samsung Electronics and HTC are announcing new flagship models, Orange is launching a smartphone at the other end of the spectrum. The Klif is a 3G smartphone based on Mozilla’s Firefox OS platform. It has a 3.5-inch screen and a dual-core processor from MediaTek.Firefox OS is an open source platform built around applications and a user interface written in HTML5, CSS (Cascading Style Sheets) and JavaScript, and Mozilla Foundation is pitching it as a cheaper and more open alternative to Android and iOS. Orange says it was the only platform to meet its requirements on both price and a good user experience. For now, Android can’t get quite as low, according to Orange.To read this article in full or to leave a comment, please click here

ZTE’s Grand S3 smartphone scans eyes for authentication

ZTE is taking biometric authentication in a new direction with its Grand S3 smartphone, which lets users log into their phones with eye scanning.By including fingerprint recognition on its iPhones, Apple helped legitimize biometric authentication for phones. But fingerprints aren’t the only thing that can be used to authenticate, so in collaboration with EyeVerify, ZTE has integrated retina scanning technology in the customized front camera of the new Grand S3.For now, the Eyeprint ID feature only controls log-in, but ZTE has plans to expand the feature to work with apps. The underlying technology works by identifying unique vein patterns in the human eye. It doesn’t take a picture, but shoots a short video to ensure the right person is trying to access the phone.To read this article in full or to leave a comment, please click here

Acer going all in with Windows 10 smartphones

Acer didn’t embrace Microsoft’s Windows Phone 8.1 OS for smartphones, but it’s really warming up to Windows 10.The Taiwanese company plans to launch more Windows 10 smartphones as it looks to bring a consistent user experience across its phones, tablets and PCs, said Wahid Razali, marketing manager for Acer in Europe, at the Mobile World Congress trade show in Barcelona. Unlike its predecessor, the new OS makes it easier to share content and use the same applications across the range of Windows devices.Acer has mainly offered Android smartphones in the past, but Windows 10 has made it rethink that strategy. It’s one of the only PC makers that can offer Windows on tablets, laptops and smartphones, which makes adoption of the OS on handsets an easy decision, Razali said.To read this article in full or to leave a comment, please click here

Review: Hosting WordPress with GoDaddy

GoDaddy recently entered the turnkey WordPress hosting fray, offering a one year trial for $1 a month. I had been toying with the idea of another blog, so I decided to give them a try. The experience of hosting at GoDaddy has been...sort of neutral.

Filtering .raw fields with Python Elasticsearch DSL High-Level Client

It took me a while to figure out how to search the not_analyzed ".raw" fields created by Logstash in Elasticsearch indices, using the high-level Python Elasticsearch client. Because keyword arguments can't have attributes, Python throws an error if you try it the intuitive way (this assumes you've already set up a client as es and an index as i, as shown in the docs):

Instead, you create a dictionary with your parameters and unpack it using the ** operator:

This produces the Elasticsearch query we want:

Installing cAdvisor and Heapster on bare metal Kubernetes

If you’ve spent some time with Kubernetes, or docker in general, you probably start to wonder about performance.  Moreover, you’re probably wondering how to gauge performance of he overall host as well as the containers running on it.  This is where cAdvisor comes in.  CAdvisor is a open source tool for monitoring docker and it’s running containers.  The best part about cAdvisor is that it has native docker support and is super easy to integrate into an existing Kubernetes cluster.  Additionally, cAdvisor runs in a container (starting to see why docker is awesome?) so the configuration changes required on the host are super minimal.  AKA – You just need to tell the host to run the container.

In addition to installing cAdvisor on our bare metal Kubernetes cluster, we’re also going to install another awesome open source Google tool call Heapster.  Heapster gathers all of the data from each Kubernetes node via cAdvisor and puts it all together for you in one spot.

So let’s get started with installing cAdvisor…

The cAdvisor container needs to run on each host you want cAdvisor to monitor.  While we could do this through the Continue reading

Experimenting with Docker, Registrator, and Consul

Over the last few days, I’ve been experimenting with Docker, Registrator, and Consul in an effort to explore some of the challenges involved in building a robust containerized infrastructure. While I haven’t finished fully exploring the idea (and documenting what I’ve learned), I did discover one interesting—and unexpected—interaction.

Here’s a quick overview of my testing environment:

• I used two OpenStack Heat templates to spin up two clusters of 5 instances each.
• The first cluster is a set of CoreOS Linux instances, customized via cloud-init to not run etcd. These instances are attached to a VMware NSX-powered logical network using IP addresses from the 10.1.1.0/24 subnet.
• On each CoreOS Linux instance, I have Registrator running as a Docker container and listening to the Docker socket (thus listening to Docker events).
• The second cluster is a set of Ubuntu 14.04 instances running Consul. These instances are connected to an NSX-powered logical network using IP addresses from the 10.1.2.0/24 subnet.
• The two logical networks are connected by a logical router and thus have full connectivity.

Registrator, if you’re not already familiar with it, is a service registry tool that listens to the Docker Continue reading
