- Cellphone-Based Hand-Held Microplate Reader for Point-of-Care Testing of Enzyme-Linked Immunosorbent Assays — we created a hand-held and cost-effective cellphone-based colorimetric microplate reader that implements a routine hospital test used to identify HIV and other conditions. (via RtoZ)
- Amazon Launchpad — a showcase for new hardware startups, who might well be worried about Amazon’s “watch what sells and sell a generic version of it” business model.
- Challenges to Adopting Stronger Consistency at Scale (PDF) — It is not obvious that a system that trades stronger consistency for increased latency or reduced availability would be a net benefit to people using Facebook, especially when compared against a weakly consistent system that resolves many inconsistencies with ad hoc mechanisms.
- The White House’s Alpha Geeks — Megan Smith for President. I realize now there’s two things we techies should do — one is go where there are lots of us, like MIT or Silicon Valley or whatever, because you can move really fast and do extraordinary things. The other is, go where you’re rare. … It’s almost like you’re a frog in boiling water; you don’t really realize how un-diverse it is until you’re in a normal diverse American innovative community like the President’s team. And then you go back and you’re like, wow. You feel, “Man, this industry is so awesome and yet we’re missing all of this talent.”
Tim O’Reilly’s Solid Conference keynote highlights the capabilities that will let us shape the physical world.
O’Reilly’s keynote address at the Solid Conference in 2014 explored the human-IoT link. The talk expanded the scope of the IoT, making it clear this isn’t just about individual devices and software — we’re creating “networks of intelligence” that will shape how people work and live.
The talk has become an essential resource for us as we’ve investigated the blurring of the physical and virtual worlds. That’s why we decided to put together a text-friendly version of the presentation that’s easy to scan and reference. And since we think it’s so useful, we’ve made the text version publicly available.

The importance of network architecture on the Internet of Things
This article is part of a series exploring the role of networking in the Internet of Things.
There are a lot of moving parts in the networking for the Internet of Things; a lot to sort out between WiFi, WiFi LP, Bluetooth, Bluetooth LE, Zigbee, Z-Wave, EnOcean and others. Some standards are governed by open, independent standards bodies, while others are developed by a single company and are being positioned as defacto standards. Some are well established, others are in the early adoption stage. All were initially developed to meet unique application-specific requirements such as range, power consumption, bandwidth, and scalability. Although these are familiar issues, they take on a new urgency in IoT networks.
To begin establishing the right networking technology for your application, it is important to first understand the network architecture, or the network topology, that is supported by each technology standard. The networking standards being used today in IoT can be categorized into three basic network topologies; point-to-point, star, and mesh. Read more…
