Three amazing Ubuntu Distros of Linux for 2017

We all love Ubuntu. It has over the course of past twelve years become one of the most popular Linux Desktop Distribution in the world. In this time it has also spawned a whole generation of amazing Ubuntu distros based upon it.

Over the past many years, we have tested many of them. Some were really short lived, like GOS that we reviewed back in the day. But others, like ZorinOS, have survived and grown tremendously and have built a strong following of their own.

Mycroft – Open Source AIexa like Artificial Intelligence

Amazon’s Alexa, Apple’s Siri and Google Now have become our defacto assistants for most things mundane.  Making calls, setting appointments or reminders, streaming music, turn on lights, playing games among dozens of tasks are now handled by them.

But this space is still young, Microsoft’s Cortana, IBM’s Watson and a host of other tech giants are trying to make their mark. But as it stands today, all these platforms are built by billion dollar companies to be used on their propriety hardware/technology stack. That all has changed with the arrival of Mycroft.

How to check elapsed time in Terminal

When we have processes running for a while and we want to know how long they have been running, there are a few nifty ways we can check them on Mac and Linux/Unix. Here is one such method to check elapsed time in BASH.

First grab the process ID (PID) using the following command. In the following command, we are trying to grab the process ID of mongoDB.

pgrep mongo

pgrep command tells shell prompt on Mac/Linux/Unix terminal to capture the process ID (PID) of the process we are interested. In this case it is mongoDB.

Kano Kit – An idea worth betting the future of your kids education

It was not long ago, when Kano announced their intentions through a Kickstarter campaign to build a “computer and coding kit for all ages” powered by a Raspberry Pi. They asked for a meager US$100,000 to achieve their ambitious goal. The idea was an instant hit with backers. Within a short time, Kano amassed over 13,000 backers which ultimately resulted in 1.5million dollars successfully raised for the project!

The kit consists of a Raspberry Pi computer, hooked with a speaker, a wireless keyboard and connected to the internet through Wifi. The computer can be connected to any monitor/LCD screen through the provided HDMI cable.

Three open source apps that can replace everyday software

Google Chrome, iTunes, and Microsoft Word are only some of the most popular programs that people use every day on their computer. But did you know that there are alternatives to the aforesaid programs that provide fantastic features?

Thanks to the accessibility of tutorials in the Internet age, hundreds of non-commercial programs have been developed to suit the needs of different end users. Indie game developers, for instance, have long jumped in on the bandwagon of using HMTL5 for the creation of games. Gaming Realms, one of the oldest software developers of casino games and operator of entertainment site Pocket Fruity, now uses the more modern HTML5 in the development of its titles to deliver high-definition gaming to its clients. HTML5 is widely used for its ability to port games to different platforms.

Building a Baby Monitor on Raspberry Pi – Part 1

In order for us to build a successful baby monitor, we need our Raspberry Pi to perform the following tasks:

  • Capture live video feed of the baby
  • Stream live video feed to browser to be viewable by any device (Phone, Tablet, PC etc)
  • Capture live video feed and save it onto a hard drive for later viewing (Nanny Cam)
  • Capture audio (optional) of the baby and stream it. For me, this is not a high priority.

We need the following hardware tools to build our baby monitor:

  • Raspberry Pi + Casing + Power supply (or battery pack)
  • Pi Camera + Casing (Some people have converted their USB webcams to do this, but I prefer the Pi Camera for this tutorial
  • SD Card preferably 8GB with Raspbian installed on it.
  • Wifi USB dongle (incase if you do not want to use the ethernet port for LAN connectivity)
  • A micro hard drive or a USB flash drive for video recording (optional)

The above items can be easily purchased from dozens of vendors across the globe and information can be sourced from Raspberry Pi website.

Raspberry Pi – Computer for the Internet of Things Age

In an era of mobile computing, Internet of things and collapsing PC sales, one computer keeps surprising its competitors by outselling many established brands. Raspberry Pi, is a credit card sized single board minuscule computer which has sold well over 2 million in its first 20 months of launch and still going strong.

The devices are loved by not only computer geeks who are building amazing products out of it, but are also found on college campuses, school labs, home automation and even powering websites and supercomputers of sort out there. It seems only our imagination is the limit.

Google itself donated over 15,000 of these devices to UK schools for kids to play and learn computing. And has also open source developed software development kit for children to learn programming.
