So, I've been battling with updating my node.js via apt-get, for some apparent reason seems like they've discontinued updates or maybe I've been doing it wrong all along - who knows. But I found a way to bypass apt-get and go back to the basics. Note: This assumes that the latest release is node-v7.4.0, else you can go to https://nodejs.org/dist/latest and get the required build. This assumes the Raspberry Pi... [Read More]

https://www.youtube.com/playlist?list=PL_VWrf_GRsBxr38XZuRrFHBBI3EpLQJ29 So after completing my diploma, and it becoming redundant in the working industry. I had to set my eyes on a Bachelor's degree. Trust me it was not easy, in the sense of being a part-time student, full-time employee, a father, a fiance and being stuck on some island for 15 months then when you come back you're residing in Cape Town and the university in Pretoria. I think... [Read More]

I have always been conservative when it comes to saving electricity in my household not because I want to but because 1 kWh costs me R1.87, hence I had to think of a better solution rather than running my server 24 hours per day with an average load wattage of 532W, if one does the maths it costs me roughly R23.87 per day when always on. So not cool, hence why I... [Read More]

A while back I was unfortunate in such a way that my HDD that I primarily use as photo archive started having mechanical issues, and before It died on my arms I had the opportunity to backup most of my pictures, however most of them were truncated and had to be discarded and the ones I could recover their filenames where overwritten with random filenames and ascii codes. For over... [Read More]

Credit goes to Author:falko Replacing A Failed Hard Drive In A Software RAID1 Array. This guide shows how to remove a failed hard drive from a Linux RAID1 array (software RAID), and how to add a new hard disk to the RAID1 array without losing data. NOTE: There is a new version of this tutorial available that uses gdisk instead of sfdisk to support GPT partitions. 1 Preliminary Note In this example I... [Read More]

Create ~/.inputrc and fill it with this: "\e[A": history-search-backward "\e[B": history-search-forward This allows you to search through your history using the up and down arrows … i.e. type "cd" and press the up arrow and you'll search through everything in your history that starts with "cd". It's a little bit like ctrl-r (mentioned in many of the comments below), but anchored to the start of the line, and the arrow... [Read More]

Setting up WiFi connection Start by booting the Raspberry Pi, connected to a display and a keyboard. Open up the terminal and edit the network interfaces file: $ sudo nano /etc/network/interfaces This file contains all known network interfaces, it'll probably have a line or two in there already. Change the first line (or add it if it's not there) to: auto wlan0 Then at the bottom of the file, add... [Read More]
