BLE Hello World in Cordova/Phonegap

After learning about bluetooth smart, I have been wanting to write some phonegap/cordova apps for my self. There are few plugins (1,2,3) available on github but in my opinion the most promising one is from EvoThings called cordova-ble. I decided to write my self a sample app for scanning on a weekend and ended up modifying one of the examples from EvoThings and mixing in topcoat and zepto as per phonegap expert recommendations. Code is here.

The code is dead simple, so I won't bother to explain it, but essentially it is just HTML5/CSS3/JS stitched together with the evothings plugin.

YubiKey Neo + Putty SSH + Windows

I have been using Yubikey Neo to manage my OpenSSH key in a CCID at work. I have made it work in Ubuntu and MacOS with relative ease, but most of my colleagues are on Windows and wondered how this could be done on the M$ platform. So I decided to give it a shot and try it out on their newly released Windows 10 (or shall we call it WinOS X  ) Step 0: Get YubiKey Neo configured as CCID Of course you have to buy this hardware before we can even begin. Before your Yubikey appears as a CCID  you will need to use YubiKey Neo Manager to enable it. See the following screenshot.  You cannot have a password for your Yubikey when you are changing the modes. If you do then you will have to delete that configuration with YubiKey personalization tool. Make sure to exit the GUI applications before you start using console later. Step 1: Check if you Yubikey works. You will need have gpg executable installed.  Gpg4Win  to interact with your Yubikey C:\...

As native as possible

This is a half baked idea and kind of a rant. The idea is very simple and has to do with my personal position position about how to choose technologies. When building a software systems, first do things as natively as possible for your context. As a software developer I would like to construct systems that are easy to get started with, understand, maintain and still can be delivered on time. As you may know that it is impossibly hard to do so many things well in any domain. In my brief career I have seen many examples of technology stacks and systems which try to achieve the previously stated goals by abstracting away complexities of underlying layers but also creating some of their own. If you are a Java server side developer you probably have worked with likes of Hibernate etc (which helps you create database queries). This usually results in poor results and has been discussed in community  (to quote "the resulting cakes  from cake mixes generally taste worse tha...
