There are many places data sets are available for free, I have collected following links over the periods, many of them for learning purpose, there are few for real serious for problem solving.

UCI have famous data repository at http://archive.ics.uci.edu/ml/

Very good weather data at for at http://www.knmi.nl/climatology/daily_data/download.html

Swift, new programming language from Apple entered ‘TIOBE Index’, a measure to track popularity of programming languages, for first time at position 16.

‘C’ tops the list as all time favourite, followed by Java, Objective C, C++ and C. When ‘Go’ debut few years ago, it had similar position as ‘Swift’ but later fall behind other languages. ‘Swift’ is in little advantageous situation as it is aimed very specifically towards millions of iOS, Mac OS developers, hopefully it should not face similar fate as ‘Go’. Right now ‘Go’ is at 30 behind Pascal, COBOL. In order to try ‘Swift’, XCode 6 is required, which is in Beta as of today.

It is seamless to stream media playback with in chrome browser tab, but no straight forward easy way to stream local media content to Chromecast. The experimental desktop sharing from the drop down in Chromecast extension have issues with audio. There are plenty of solutions discussed here.

But one easy solutions I found it working is using Videostream. Install it from here. Though it is a browser extension it doesn’t appear on browser. Launch it from Launchpad, it opens up a browser tab. Select the file and run. Done :)

There is no doubt that Apple and Google dominate mobile world, - Apple with vertically closed model of integrated hardware and software and Google with open software and varying different hardware partners, both of them occupy 90% mobile market share overall. Both the companies determine the shape of how future of mobile computing is going to be.

At this juncture, it is noteworthy to take a look at two executives from Apple and Google. Both of them taking center stage recently in designing mobile user experience, by defining the future of how two dominant operating systems user interfaces should look like, and how the user experience should be designed on their respective parent companies’ operating systems.

First, Jonathan Ive, once an industrial design engineer, now Vice president of design at Apple. Second, Matias Duarte, designer of Palm’s WebOS, and now Vice President of Design at...

Few days back, I shared training data for predicting gold price, it got few users from ML students community, and lot of queries on how I cleaned up the data and models which I used. So I am sharing the training data, test data (after cleaning up).

Google and Apple announced its foray into TVs and Autos recently. ‘Compute Continuum’, a phrase spread headed by Intel, which refers to a computing paradigm where an user’s ability to use an application with its last known state across different devices or ability to access applications, its state from any device, appears to be finally arrived.

Few hypothetical scenarios of compute continuum, may be

1. A video/music start playing from the last played position from any device when the user access the media later point of time from another device.
2. Accessing phone’s text message from desktop computer or living room TV.
3. Reading a document from same scroll point from another device.
4. Answering phone call from desktop when your phone rings.

In a nutshell, compute continuum is ability to use and access an app and its context from another device.

There are challenges in accomplishing compute...

Being a good engineering manager to every one reporting to you is very tough job, very difficult to meet everyones expectations. But bigger organizations have good people management trainings (MTP – Managing Through People, Situational Leadership etc), best practices and tools for managing people in effective way, but applying these best practices consciously day to day will be a challenging one. Here is my thoughts for being better Engineering Manager for your people, from my experience or I wish my boss should be like this.

1. No favoritism: Don’t ever show favoritism to any one. Never. Recognize the good work, but make sure every one understand good work always receive due credit what it deserves.

2. Equal opportunity: Make sure every one get equal opportunity in the team. Same opportunity for every one may not be possible. But make sure, every one in your team aware that they will get...
