Former Facebook employees launch Coolan, a startup providing predictive analytics for data centers; currently in private beta (Amir Michael/Coolan…

Coolan is live! Amir Michael 2/25/2015 Hello, world. After months of hard work, I am excited to share our first product. Coolan is a new community-based analytics solution that provides customers with visibility into the performance of their infrastructure. The service delivers insights paired with information aggregated from the data center environments of a community of operators. Using that historical data, we leverage machine learning techniques to predict failures, prevent outages, and benchmark against industry peers. Coolan helps reduce downtime and can significantly lower the cost of infrastructure — a key concern in the data center. With our powerful data analysis, we present solutions to optimize hardware and inform future purchasing decisions. Empowered by the community, we uncover issues that arise during the lifecycle of a server and bring transparency to the enterprise hardware space. How It Works We’ve worked with small startups and webscale companies, and universally, we’ve heard from DevOps engineers, data center managers, and CIOs that they want more insight into how their hardware is performing — they want hard data on real-world problems that go beyond the buzz and marketing claims. Why is my server failing? How often does it fail and can I prevent the next failure from occurring? How can I optimize the configuration of my server? What does my current inventory of hardware even look like? Did I purchase the right equipment for my needs? To answer these questions, we built a software platform that engineers, infrastructure managers, and IT teams can easily access via a dashboard and API.

Comcast launches cloud DVR in San Francisco, lays foundation for a set-top box-free future (Janko Roettgers/Gigaom)

2 hours ago Sep. 30, 2014 - 9:00 PM PDT Comcast customers in the San Francisco Bay Area can now stream their DVR recordings to their iOS or Android devices, no matter where they are. The Sling-like feature requires one of the company’s newer X1 set-top boxes — for now. Under the hood, it’s already powered by Comcast’s cloud DVR, which could eventually make set-top boxes obsolete altogether. X1 users can also watch any of their live TV channels on a mobile device within their home. This kind of feature is similar to what Dish is offering with its Hopper DVR, or some of the things Slingbox owners have been able to do for some time as well. But the infrastructure used by Comcast to power mobile playback is more unique, and foreshadows significant changes coming to the way the company operates it TV service. That’s because on late Tuesday evening, Comcast also lit up its cloud DVR infrastructure for customers in the Bay Area. This means that every TV subscriber with a X1 set-top box also immediately has access to a virtual DVR in the cloud, which is used to stream any of those recordings to mobile devices. Initially, the cloud DVR literally works as a kind of invisible clone of the DVR a customer has in her living room, meaning that each episode gets recorded twice — once on a local hard drive, and once on Comcast’s servers in the cloud. Customers will stream from the cloud DVR once they leave their house, but shouldn’t really notice the difference. In the future, Comcast is going to switch to set-top boxes without hard drives, and only keep recordings in the cloud, ready to stream to any screen as needed.

Skyhook plays the beacon game, building context into its Wi-Fi geo-location platform (Kevin Fitchard/Gigaom)

3 hours ago Sep. 24, 2014 - 12:17 PM PDT Skyhook Wireless has built one of the world’s largest databases of Wi-Fi access points, creating a geo-location network that can home in on Wi-Fi signals to pinpoint your smartphone on a map. Now it wants to use that technology to help developers design smarter location-aware apps and to help marketers better target their advertising. On Wednesday, Skyhook – which is owned by Liberty Media – launched a service for developers and advertisers to generate geofences within its virtual network and create user profiles consumers based on their location history. If it all sounds a bit like newly emerging beacon technology, that’s because there are a lot of similarities. Instead of an app getting a fix on your location by pinging off a Bluetooth Low Energy beacon, though, it’s using Skyhook’s map of Wi-Fi signals to figure out where you’re standing. Skyhook’s technology draws not just on GPS and cellular tower data, but also the millions of transmitting Wi-Fi access points that surround us (Source: Skyhook) For instance, if you enter a department store, that store’s app on your phone would wake up and alert you to the shoe sale going on the second floor. But since Skyhook’s geo-location capabilities aren’t tied to a specific business’s beacons, it can put a geo-fence around anything that might be relevant to a particular app – as long as there are nearby Wi-Fi signals to detect. So a ticket booking app on your phone could wake up whenever you’re near any movie theater and show you current film listing and screen times. The profiling feature, called Personas , is just as useful to advertisers and invasive to consumers as it sounds. Skyhook can learn a lot about your behavior by detecting the fields of Wi-Fi you traverse through everyday and making simple inferences. It knows where you live and work by detecting where you park your phone from to 9 to 5 and from midnight to 7 AM.
