How Web APIs Unlock Value in the Cloud


David Schoenbach is vice president of product management at Exadel Inc. There he heads product definition, marketing, and sales of the Tiggzi, a platform for mobile development.
The cloud is where it’s at. It’s where business data resides. It’s where social user-generated content sits, where forward-thinking creators place their tools. Unfortunately, the cloud is also the place all that good stuff stays, unused and unloved. That is, unless you offer smart ways to access it. That is where a web API comes in.
Just as the power of crowds has populated the social content repositories of Web 2.0 — YouTube videos,Facebook updates, tweets, and more — the web API enables designers and developers to re-purpose the body of knowledge that is the cloud. Here are some examples of how companies have used a web API to create more value.
  • Mashups: The Google Maps API enables mashups of any location-based data, creating new layers which can be displayed on a map in an app. The Google Map API is the most used web API.
  • Social Feedback: The Facebook Graph API powers “like” buttons in apps, and much more. It enables consistent access to objects in their system (people, photos, events, and pages) and lets developers also access the connections between them (friend relationships, shared content, and photo tags).
  • Business Tools: Salesforce.com opened their core services to partners via API, enabling them to innovate and extend Salesforce services. API traffic to Salesforce accounts for more than 60% of total Salesforce traffic.
  • Commerce: eBay alone has a developer community of more than 800,000 members using its APIs. With eBay APIs, developers can display eBay listings, get bidder information for sold items, get the current list of eBay categories, leave feedback about users, and submit new items for sale.
  • Network Operators: AT&T, Verizon, Deutsche Telekom, and others are getting in the game with APIs exposing network resources, including SMS and carrier-billing for in-app purchase. AT&T, for example, recently published more than a hundred public network APIs to stimulate app development.
These examples are just a small sampling of API creation and usage. The larger picture can be seen atProgrammableWeb, which catalogs more than 6,000 public web APIs.
From these examples we can see the following:
  • An API may expose business data such as customer data in apps only intended for internal sales staff use.
  • APIs may be deployed privately — for internal or partner use — or publicly for broadest dissemination. Businesses are enabling “citizen developers” across the enterprise to create their own apps using secure, private APIs internally or among business partners. Public APIs, such as those listed on the ProgrammableWeb, enable new and interesting uses of existing web resources.
  • Mash-ups are driven by APIs. APIs determine the resources available for the re-mixing of content.
  • Designer/developer teams are the new creative crowd, driving access to content in innovative ways.
  • As businesses ask “What’s our mobile strategy?” the API is a significant part of the answer. Businesses that don’t offer their resources via API, to be mined by the innovative worldwide community of developers, will be left behind.

Google Nexus Q: Ready for Party Fouls, Not Prime Time [REVIEW]


Google is calling the Nexus Q the “world’s first social media streamer.” When connected to your TV, this $299 ball can be used to stream tunes and videos from your favorite (Gingerbread or higher) Android device.
If you have Android-toting friends over, you can also give them the ability to control the Q and play their own music and videos.
Set to ship in mid-July, the Q is much more expensive than most music and media streaming devices. While fun to play with, the Q also has some significant flaws.

Looking Good

When Google designed the Q, it was looking to create something that you’d want to display on a bookshelf or beside your television for everyone to see rather than keep hidden in a cabinet. While some won’t be thrilled with the orb design, there’s no denying it looks a lot better than your average set-top box.
The matte finish of the Q is beautiful to look at. It’s smooth to the touch and looks every inch a $300 gadget. Recessed ports on the back of the device help you keep cords tidy and out of the way.
LEDs around the center of the Q can be customized for your space with a number of different themes. The lights will pulsate in time with the music, while a cool visualization comes up on your screen. It’s nothing you haven’t seen before, but it’s still nice to look at.
Waving your hand in front of the blue dot on the front of the Q will mute music, and sliding your fingers along the front can turn the volume up or down. The experience is pretty slick, but it’s also not exactly practical.
A pretty ball-shaped device with flashing lights begs to be touched, and likely will be everyone –including small children. During our initial hands-on with the Q, I picked it up and managed to mute the music by accident. Then I accidentally blasted the music so loud I could have broken the speakers, or maybe some eardrums. It’s a party foul in the making.

Getting Started

Setting up the Q is surprisingly simple. The HDMI cable, included, is all you’ll need to get connected to your television. Tech-savvy or not, most anyone should be able to get the device hooked up in just a few minutes.
The remainder of the set-up is done from your Android device using a special Nexus Q app, available at the Play Store or by tapping your phone on the Q to have it sent via NFC.
On-screen prompts within the app guide you through connecting your phone or tablet to the Q via Bluetooth, and inputting information about your Wi-Fi network so the Q knows where to connect. You also identify what room of your home the Q you’re setting up is going to be positioned.
You could have a Q set up with speakers in every room of your home and control all your Qs from the same device. If you don’t have Wi-Fi – or live somewhere where there’s a ton of networks to choose from — the Q can also be connected to the web with an ethernet cable.

Rock and Roll

Once you’ve gotten the Q set up, streaming music and movies is a breeze with your Android device. Tapping a play button at the top of the screen when playing a song will let you select the Q as an output device via whatever you have it connected to. That’s it.
I was able to play some YouTube videos and music on my TV with no issues. Quality looked to be as good as I typically see streaming other content over the web onto my TV, and switching from music to movies and back again worked without much lag. The Q is currently only able to play content from YouTube, Play Music, and Play Movies so you’re also pretty limited in what you can watch.

Party Stopper

The main advantage the Q has right now over its competition is its social feature. In theory you can create playlists with the Q with your friends and give everyone at your party the ability to control what music is playing and shuffle the tracks around.
All that sounds great, but when it comes time to actually trying to use the functionality -– it just doesn’t work.
I first set up my Q using a Galaxy Nexus running Jelly Bean. I tried to join a party with the Nexus 7 tablet also running Jelly Bean, and while the tablet could find the Q, it wouldn’t let me play any content on it.
Trying to access the Q from my Nexus 7 also seemed to lock the device. I can still play music and stream videos from my Galaxy Nexus, but I no longer have access to the settings for the Q.
I ran into similar problems trying to give a friend’s Android device the privilege to spin tunes: it just didn’t work, and produced error messages more often that not.
Both of my devices are afiliated with my Google account, so you would think I would be able to seamlessly connect to the Q. Not so much.

Not Ready For Prime Time

The Q isn’t on sale just yet, and that’s probably a really good thing. In its current form the software is too buggy to make it worth using at all, much less shelling out $300 for.
If you’re looking for something to stream video, there are other options out there that can get the job done for a lot less money. Some of those competing devices also offer more forms of content — Netflix, Hulu, and Spotify — than the Q can currently handle.
A solid software update -– at the very least -– is going to have to happen before the Q can make its way into consumers’ hands. Google has opened the Q up for developers, and will be interesting to see what they are able to create, and whether the Q can ever offer more functionality than its competition.

Instagram Still Down After Storm Cuts Power During Brutal Heat Wave


Popular mobile photo-sharing service Instagram is still down this morning after violent storms in Virginia knocked out the cloud computing services that run it.
Amazon’s Elastic Compute Cloud, which powers sites like Netflix and Pinterest, and SocialFlow, as well as Instagram, was impacted during the widespread power outages that affected the region.
On its EC2 support forum, Amazon posted the following updates about the N. Virginia region:
Jun 30, 1:42 AM PDT We have now recovered the majority of EC2 instances and are continuing to work to recover the remaining EBS volumes. ELBs continue to experience delays in propagating new changes.
Jun 30, 3:04 AM PDT We have now recovered the majority of EC2 instances and EBS volumes. We are still working to recover the remaining instances, volumes and ELBs.
Jun 30, 4:42 AM PDT We are continuing to work to recover the remaining EC2 instances, EBS volumes and ELBs.
Affected users took to Twitter and Facebook to rail against the service outages.
However, the storms that caused the loss of Instagram and Netflix also knocked out power across wide swaths from Indiana to New Jersey, according to the Washington Post. A large portion of the outages centered around Washington, D.C., which has just posted its worst heat wave since 1934, with a temperature of 104. Two deaths have been reported so far, both from fallen trees.
The power outage is expected to last several days

What is AWS and How Did It Bring Down Instagram?


[UPDATE: As of late Saturday afternoon, Instagram appeared to have much of its functionality restored for most users.]
Instagram has been insta-tripping since Friday night and here’s why: A powerful storm in northern Virginia took out the servers it runs on.
Maybe you’re wondering how a storm on the East Coast killed access to your favorite photo sharing app, which is based in San Francisco. That’s because Instagram, like many major web companies, uses an even bigger web company — Amazon — to host its traffic and data.
An enterprise cloud-computing product called Amazon Web Services (AWS) powers businesses in 190 countries worldwide — “hundreds of thousands” of startups and mature companies, all told, according Amazon’s website. Pinterest, Netflix and Heroku are among the notable sites and services you may be familiar with — in addition to, of course, “your Instagram.”
Some call AWS the Coke of the web hosting industry, so that gives even more of an idea of just how prevalent it is.
AWS operates out of Oregon and northern California in addition to northern Virginia, but only the Virginia facilities were affected in Friday’s storm. Still, that’s enough to have people wondering how they’ll see filtered Saturday brunch photos, as well as enough to make “My Instagram” trend worldwide on Twitter for several hours. (Pinterest and Netflix were back up by Saturday morning.)
The outage to Instagram and other major sites shows that — despite massive hype and momentum in the Internet world — cloud computing isn’t necessarily a magic solution for businesses data and IT needs.
Amazon began offering the AWS service in 2006. It lets businesses host apps and websites, backup and store data, and generally run their enterprise IT. The idea — as with cloud computing in general — is businesses can stay more nimble by accessing servers from a remote location and renting space and capacity as needed. Scaling becomes easier and companies without resources for dedicated server hardware don’t have to worry about that side of the business — until something like this happens.
One product AWS offers is called Elastic Load Balancing as part of its Elastic Compute Cloud (EC2) service. This means a business can pay to set up EC2 service in multiple areas. Then, when service in a particular availability area isn’t working — say, because of a huge storm — traffic is automatically rerouted to another, healthier availability area. Then load balancing is restored once all availability areas are healthy.
But if a company — say, for example, Instagram — doesn’t have Elastic Load Balancing set up and has all of its IT needs hosted in just one AWS service area — say, for example, Northern Virginia — and a problem occurs, then it’s a more serious issue. What’s unclear is whether Instagram put all its data eggs in one AWS basket and in part brought Friday and Saturday’s extended downtime upon itself, or whether AWS is failing Instagram entirely.
Mashable has contacted Instagram for comment, but so far not received a response. Amazon tells us it will release more information about the outages “in the coming days.”

In a Relationship: College Students and Their Smartphones [INFOGRAPHIC]


College students aren’t just concerned with getting good grades and finding the best parties. More than ever, they’re using their smartphones to navigate life on campus.
On the bus, waiting in line, in bed, on the treadmill and even while driving, college students can’t seem to put their phones down. Fifty-two percent say they often check their phones before getting out of bed in the morning, according to one study. Nearly half do so while in bed at night before they fall asleep.
Thirty-five percent say they sometimes use their phones while driving but stopped at a red light, and nearly 20% say they sometimes use them while the wheels are even moving. But it’s not all addiction and danger. Forty-five percent of college students say smartphones frequently help with school assignments, and 46% say they’re often helpful for work-related tasks.
The Internet education portal OnlineColleges pulled this data and more from sources including the Pew Internet & American Life Project, University of Colorado and Nielsen to produce the infographic below.
Among other notable findings: More colleges students use iPhones than any other device, email has nearly caught text messaging as the most popular use for smartphones among college students and nearly half of students use their phones to check the weather.
Check out the full infographic below for more information and let us know in the comments — do you think smartphones are doing more to distract or help college students?

Healthcare Ruling Sparks 13,000 Tweets Per Minute


The Supreme Court’s decision on the Affordable Care Act, often referred to as “Obamacare,” set off a frenzy ofTwitter activity on Thursday, peaking at 13,166 tweets per minute, according to @gov.
Obamacare-related tweets narrowly missed dethroning President Obama’s 2012 State of the Union address as the most-tweeted event in recent political history (the address generated a peak of 14,131 tweets per minute).
The most activity on Twitter, according to @gov, surrounding the ruling occurred at 10:17 a.m. ET — the time when users of the social network were trying to sort out conflicting reports of the court’s decision.
After the decision, politicians and citizens took to Twitter to express their support or opposition of the court’s decision. Republicans and conservatives, who decry the Affordable Care Act as a government overreach, used hashtags such as #FullRepeal, #Obamatax and #ObamacareInThreeWords to rally their socially-savvy base. Democrats and liberals fought back with #ACA and a slew of YouTube videos arguing that the bill has made life easier for many Americans.
Some tweets may have gone a bit too far — Patrick Gaspard, executive director of the Democratic National Committee, later apologized for this reaction that went viral:
Republican presidential contender Mitt Romney’s campaign was able to turn the right’s disdain for Obamacare into cold hard cash: In 24 hours, it raised $4.6 million through more than 47,000 online donations. Its social followers are reportedly up as well.
What exactly were the rest of Twitter users posting about the court’s decision?
Social media analysis firm Crimson Hexagon took a look at about 130,000 Obamacare-related tweets posted on Thursday. Its analysis shows that 48% of those tweets were in support of the Affordable Care Act, 29% of tweets called for its repeal while 22% were neutral, merely spreading the news of the court’s decision.
