Druid | Interactive Analytics at Scale
Druid is primarily used to store, query, and analyze large event streams. Examples of event streams include user generated data such as clickstreams, application generated data such as performance metrics, and machine generated data such as network flows and server metrics. Druid is optimized for sub-second queries to slice-and-dice, drill down, search, filter, and aggregate this data. Druid is commonly used to power interactive applications where performance, concurrency, and uptime are important. Druid was initially created to power a scalable, visual, multi-tenant application where users could not only rapidly slice and dice data to create ad-hoc reports, but also interactively explore data to quickly determine the root cause of patterns and anomalies. Druid is designed from the ground up for sub-second queries, which are critical in interactive applications as usability studies have shown that humans get distracted and lose their train of thought if responses take longer than a second.

CC3000 Smart Config - transmitting SSID and keyphrase ~ Depletion Region
So let's start at the start - we have a problem - we want to send two pieces of information, an SSID and the keyphrase, from one party that is already a member of the wifi network to an external party who can monitor all the encrypted wifi traffic but who cannot decrypt it.

Someone who cannot decrypt the wifi traffic can still see quite a lot of information, e.g. they can see the source and receiver MAC addresses of every packet sent.

They can also see the length of the data portion of the pac...

Non-Invasive Biosensor on a Chip [video] | Health Tech Insider
Researchers at the Australian National University (ANU) in conjunction with teams in Australia and Sweden have developed a tiny gas sensor that is about 50 times smaller than a human hair. They are fabricated on chips and rely on pulses of light to trigger measurements. They operate at room temperatures, and are sensitive to extremely small concentrations of the target gas. They are so sensitive that they can even detect gas biomarkers that escape through the skin. The result is a sensor system that could easily incorporated into wearable devices, including a smart watch. It is possible that these sensors could eventually reduce or even eliminate the need for many blood tests.

DFree - Toilet Timing Predicting Device
DFree detects the changes in bladder size and predicts urination timing.
DFree needs to be placed 20mm above the pubis to detect the bladder properly. DFree uses harmless, non-invasive ultrasound sensor. DFree sends alerts to your smart devices when it is time to go to the toilet.

How to Fit Large Neural Networks on the Edge – Heartbeat
Deploying memory-hungry deep learning algorithms is a challenge for anyone who wants to create a scalable service. Cloud services are expensive in the long run. Deploying models offline on edge devices is cheaper, and has other benefits as well. The only disadvantage is that they have a paucity of memory and compute power. This blog explores a few techniques that can be used to fit neural networks in memory-constrained settings. Different techniques are used for the “training” and “inference” stages, and hence they are discussed separately.

How to Mash Up BLE, NodeJS, and MQTT to Get Internet of Things@ Hackaday
n a previous article I walked though a small python script to talk to a BLE light and used it to cycle through some colors. Now I want to delve deeper into the world of Internet Connected BLE devices and how to set up a simple Internet-Of-Things light. With this example in hand the sky’s the limit on what you can build and what it will be able to do.

Join me after the break as I demonstrate how to use NodeJS to bridge the digital world with the physical world.
