Run a Second Linux Desktop with QEMU and KVM [10] Sometimes a bit of testing saves the day if you can do it on a disposable Linux machine of some sort. That testing could include installing new software that might be a little invasive, installing lots of hidden, tiny files that would clog up your desktop machine, or maybe trying out unstable software that is not fully released, meaning that your desktop machine might not boot up post-installation. Equally, you might be writing system scripts that you need somewhere safe to run in case they break your other precious settings. In this article, we will look at running a second Linux desktop, or virtual machine (VM), inside your main desktop. To do this, we will be using a fantastic piece of virtualization FOSS software called QEMU. It dutifully sits atop the second-to-none KVM, which provides a lower level of virtualization. If that sounds confusing, there's more information in this article. Among the many benefits, one considerable advantage of using QEMU and KVM is that you have a wide range of Linux distributions that you can install on the second desktop, giving you lots of flexibility.

Plasma secrets: additional languages and keyboard layouts [12] Welcome to the latest installment in my neverending Plasma desktop games. Today, I want to talk to you about something that is both trivial and complex. The use of other languages on your computer. While I fully believe the only acceptable machine interface language ought to be English, I also understand and appreciate that other people speak and use other languages - after all, I do it myself, four or five languages. You see, I just bragged there. On a serious note, sometimes one may need to use non-ASCII 127 keyboard layout. And when that need strikes, you want your operating system to give you friendly help. Well, in today's guide, I want to show you the clever way the Plasma desktop handles languages and keyboard layouts. Powerful, elegant, and follow me. GNU Linux (Debian 10) ? how to show and remove all (privacy intrusive) meta info from jpg pictures[13] meta infos in jpg pictures can contain quiet a lot of sensitive data: what date the picture was taken with what camera/phone (Samsung Galaxy S3 did that) maybe even: GPS info/location of the picture who/what tools processed the picture of course as always, this data can be put to good or bad use privacy wise it would be probably the best to simply delete it all Migrating Two Factor Auth [14] I use a ton of services which either require or recommend 2fa as part of the authentication process. I used to use ?Google Authenticator? then more recently ?Authenticator Plus?. However Authenticator Plus seems to be no longer maintained. So while I have no problems with it, I think it is time to migrate to something else. Step up, Aegis Authenticator, a free, open source authenticator app, available on the play store, and F-Droid.
