What is dynamic locking in Windows 10?

 It is a security feature that locks up your computer/laptop when you are away (out of the Bluetooth range) from the computer. You can use this feature with your Bluetooth-enabled SmartPhone, Bluetooth headset, etc.

It is possible to lock the computer with Windows Key+L but the dynamic key can be useful when you forget to log out or go to sleep.

The "Dynamic Locking" feature is by default inactivated but you need to activate it.

Here are some screens that may be useful to you. I have paired my Samsung smartphone with my laptop.

What is the difference between Standard HTML5 and HTML5+Cordova Project in Intel XDK?

In all my previous posts in this blog we only looked at Standard HTML5 projects. In Standard HTML5, the project was packaged as a web app and host it on a server (the Intel XDK server in this case) as an HTML5 web app, or build it for distribution via popular mobile app stores. For testing purposes, you would use the Intel XDK Preview app available from app stores. There are couple of examples and posts on this site. Standard HTML5 Projects are built for Desktops, smartphones and tablets.


The HTML5+Cordova projects on the other hand are built for smartphones and tablets for all of the following OSs: android, iOS, Windows and also as a web app.


The pages you create use both the Standard HTML5 and Cordova APIs and can be distributed via popular app stores.
You will be devleoping as a hybrid mobile app that can,

  • Use sensor data on the phone including camera, gps, accelerometer etc
  • Access device hardware;Near field communication(NFC); Bluetooth, Camera etc
  • Manage file storage and caching. Also access databases like calendars, contacts
  • Work with third-party plug-ins
More on Cross-Walk here:
Cross-Walk is also android specific but built on Open Source foundation.

What is the difference between Arduino UNO and Arduino 101?

First of all Arduino (iconic name) is common to both of them and both of them use the same kind of connectors and periferals.

Arduino UNO used the ATmega 328 processor but the heart of Arduino 101 is an Intel Curie board with two cores, an x86 (Quark) and an ARC Argonaut RISC Core). These two cores enable high performance and low power-consumption.

Arduino UNO adds on-board Bluetooth Low Energy and 6-axis accelerometer / gyroscope capabilities. This means Arduino 101 is more powerful than Arduino UNO in terms of remote (Bluetooth) operation and accelerometer capability. Arduino UNO has no such capability.

In order to access Arduino UNO remotely you would need a Wi-Fi shield.

Arduino 101 has libraries for the following embedded peripherals :

CureBLE (to control Bluetooth Low Energy module)
CurieIMU(to control the 6-axis accelerometer + gyro)
Curie Timer One (to control Timer functions)

The above libraries are installed with Intel Curie core.

In order to work with the Arduino 101 you would need Arduino 1.6.7 software or later.

In my previous post you have seen how to work with Visual Studio 2015 Community for Arduino. You can use Visual Studio Community with Arduino 101 as displayed here:

In my next post I will discuss how to install the latest version of Arduino to work with Arduino 101.
