Within these fine pages we have more Python, more Podcast production, N more Inkscape, and a piece on Ventoy for both Linux and that other OS of whom we shall not speak. "Ventoy? What's Ventoy?" I hear you ask. It's a little known piece of software that you install on a USB stick. Once it's installed you then simply copy distro ISO files onto the USB stick. And, like magic, it'll boot to a menu with your ISO files ready to run. It's bordering on witchcraft. Elsewhere, we have Erik starting another short C&C series. This time on using LMMS. Richard continues with his quest for the holy grail of cookery software. Then, Adam brings us a look at Ubuntu Unity 20.10. Find Full Circle on: New year, new you. Please consider submitting an article. The reserves are running low and facebook.com/ Erik is, in all honesty, keeping the magazine afloat with articles (C&C, Q&A, game reviews, How-To's fullcirclemagazine etc.). Without him and the host of regulars this magazine would have sunk years ago. Please send an article on whatever subject you love the most. It can be a review of software, hardware, even a twitter.com/#!/fullcirclemag book. Your story of how you got into Linux. Anything. All it takes is a couple of regular writers to http://issuu.com/ leave and the magazine will shrink or sink. fullcirclemagazine https://mastodon.social/ So, after some doom and gloom to start the year: send some articles! @fullcirclemagazine All the best for 2021!
