Knoppix 7.4: whom is it for?

I have already tried to write about this distribution couple of times. The last time that happened more than 4 years ago, when I reviewed Knoppix 6.4.

4 years passed by, and now I had an order from buylinuxcds.co.uk site to dispatch an USB stick with Knoppix.

The most recent version of this distribution is Knoppix 7.4.2. It has been released in September 2014. The ISO image size is just under 4Gb. I downloaded it via torrent.

Unfortunately, Knoppix is not the distribution you can write to a USB stick using the dd command or Ubuntu's built-in tool. You basically have three choices:

  1. use Unetbootin,
  2. use the long and windy way described on official site, or
  3. write a DVD.

I tried option 2, but gave up after approximately 10 minutes of going round. Option 1 simply worked.

So, USB stick is in the port of my laptop Toshiba Satellite L500-19X. Reboot. Choose to boot from USB. Let's go!

Linux Mint 17.2 KDE: do you have the hardware?

August 2015 is only half-through, but it has already seen releases of two popular Linux distributions.

DarkDuck has already reviewed Zorin OS 10 Core.

Today is the turn of Linux Mint 17.2. Yes, you are right. Linux Mint released the version 17.2 in August 2015. Of course, they are not their "major" Cinnamon and MATE editions, but rather slightly less popular flavours: KDE and Xfce.

Image size of Linux Mint 17.2 KDE is about 1.6 Gb, which is 0.2 Gb more than the Cinnamon edition. I downloaded it using the torrent link available on the web site and "burnt" onto the USB stick using the built-in tool of Ubuntu 14.04.

So, the USB stick is in the port of my Toshiba Satellite L500-19X laptop. Reboot. Choose to boot from USB. Let's go!

Zorin OS 10 Core: install and forget

You may have noticed that DarkDuck publishes articles about certain operating systems more often than others. They are LinuxMint, Emmabuntus and Zorin OS. The reasons are different, though I can tell you that I keep good relationships with both Emmabuntus and Zorin teams. That's why I cannot miss a chance...

And there is a chance this time!

It has been more than a year since Zorin OS 9 was released. And the 1st of August 2015 saw the release of the brand new distribution from the Zorin team: Zorin OS 10.

I downloaded the image of Zorin OS 10 Core 64-bit from the official site. It is easy to navigate, though a torrent option is definitely missing for downloaders. ISO image size is just below 1.5 Gb in size.

Then I faced the same issues with Zorin OS 10 that I previously had with Emmabuntus 3.1.01. Neither Ubuntu's built-in image writer tool, nor the dd command worked for me. Unetbootin helped me to deal with Zorin OS image this time.

So, USB-stick is ready and plugged into the port of my Toshiba Satellite L500-19X laptop. Reboot. Choose to boot from USB. Let's go!
