Converting MKV video is super fast via terminal. This can be done on Linux or Mac.

Install ffmpeg

sudo apt-get install ffmpeg
sudo brew install ffmpeg


To convert video.mkv to video.mp4 use the command below:

ffmpeg -i video.mkv -vcodec copy -acodec copy video.mp4

This 183MB file took less than 20 seconds to convert.screen-shot-2016-09-22-at-22-13-42

This 183MB file took less than 20 seconds to convert.

Tip: To convert all the mkv files in current directory, run a simple loop in terminal:

for i in *mkv; do ffmpeg -i $i -vcodec copy -acodec copy $i.mp4; done

Just the moon!

So when I’m not writing tech stuff, I turn to my favourite passion that is photography. Just got a glimpse of this space floating beauty out the window and though I’d better click that. Got my Canon out to snap it and Instagram it eventually 🙂

Ask any photography enthusiast, professional; ‘Autumn’ would be the most likely answer to the question ‘What’s the best time to take photographs?’

Today, I had some time to walk around Wakehurst Place, a branch of Kew Gardens in the UK to snap some shots. It’s been a very long time since I used my SLR as I was held up with my MSc and other mental commitments!

Herts Got Talent

Hello all,

Been to this fun-filled event organised by the Mixbag society at University of Hertfordshire last night [5 march 2015]. This was an ultimate mix of multi-cultural events and multi-faceted performances. Here are some snaps from the event.

(Apologies for the exposure In some pictures and also, if I have missed any of your snaps)

iPhone Photography Gallery

Ok so Apple today updated their website with a whole page dedicated to the amazing photographers (or iPhoneographers) choosing the best iPhone photos taken by users. As an amateur photographer since a very young age, despite being an apple fanboy as people call me, I have had immense respect for the work put into the iPhone camera in an unbiased perspective. What attracts me is how natural the photos look when taken on the iPhone camera. Due credit should be given to the sensor by Sony. What is striking is the post editing of the JPG files done by iOS.

Don’t miss checking this page out by Apple

Eye candy.

Mac OS X : Mission Control

This is an article I believe will be of immense help in improving productivity/ efficiency in the way people use their Macs. I have noticed the recent up-trend in MacBooks. I do believe this is partially for the repute and the brand and its slick looks (yes, the illuminated  logo).

The most efficient tool is Mission Control which can be set up from preferences. The reasons this is handy is because many of us tend to run various applications at the same time. While running 5 applications on a Mac is no problem, the experience can be enhanced if you can get all the clutter off right? Look at the image in exposed view, below:

Mac OS

You can also notice that there are some desktops (virtual) on top. I can assign each of these applications on to the 4 separate desktops in my case (you can go up to 16). This way, all I need to do to switch between applications is a four-finger swipe on the trackpad! This is very helpful if you’re writing articles based on knowledge articles from the web, running VMWare etc. Running Windows and Debian, I can switch between Mac OS X and Windows/ Linux in just a swipe.
