The power of data analytics
Electricity is a (very) expensive resource in Europe. By putting the servers into sleep/suspend mode (while idle), I can save 80% of the power consumption. A very-low-energy microcomputer (e.g. raspberry pi or even the smartphone) is enough to get them to wake up when being used.
Long time not checked Tableau, this application has incorporated new connectors for recent technologies, e.g., Google Big Query, Spark SQL, etc. It surely positions itself as the ‘de facto’ distributed visualization platform for big data. I was wondering when Tableau delivers its desktop version on Linux platform.

It’s a big ecosystem. Just get the deployment … Read moreMicrosoft Azure IoT edge
Hardware makers are competing to make a credit card-sized single board computer (SBC) that has ‘enough’ computing power on which ‘intelligence’ can be put. As an example, a drone that could take actions immediately when perceiving a certain pattern without beforehand coordinating with the ground station. Interestingly one of them is based on Eindhoven, UP … Read moreEdge embedded system: UP core
I met a lot of potential Indonesians, but lack of English made them unconfident to deliver their capability. I just noticed Android’s conversation service atop Google Translate that could reduce the hassle. Just connecting Android to a Bluetooth earphone, we can watch 2 people speaking in their mother languages confidently. This is an example: Waverly … Read moreGoogle Conversation atop Translate API
Turning a remote controller into a (WiFi) lamp switcher using a Sonoff RF bridge that converts a learned RF incoming signal to an MQTT publishing action.
