February And March Linux Articles

Mar 22 3:28pm Everyday Linux User
IntroductionI am aware that it is a while since I added any content to this site. To be honest I have been inundated with work and so I have had little opportunity to write anything worthwhile on this blog.I am learning new programming techniques for my day job and this has meant watching lots of Pluralsight videos and trying out what I have learned.This doesn't mean that I have been completely idle when it comes to writing but most of the content I have written has been for and I wanted to point you in the direction of these articles because I'm sure many of them will be useful to the readers of this site.How To Install Cinnamon On UbuntuAs many of you know Cinnamon is the default desktop environment with Linux Mint and Linux Mint itself is based on Ubuntu.So why bother installing Cinnamon on Ubuntu? Why not just install Linux Mint? Well if you want the traditional look and feel of Cinnamon but you have already installed Ubuntu and you have everything else working and installed the way you like it then it seems a lot of effort to go to if you decide to uninstall Ubuntu and then install Linux Mint.In addition Linux Mint is stuck on the LTS release whereas you might be one of those people who like to run the latest versions of Ubuntu.Whatever your reason this guide shows how to install Cinnamon on Ubuntu.How To Backup Files And Folders Using UbuntuHopefully you will see by this article that a lot of the articles I write at Lifewire are just as much for the Everyday Linux User as the articles on this site.This guide shows how to backup your files and folders using Ubuntu's De Ja Dup tool.How To Create A UEFI Bootable Ubuntu USB DriveOne thing that I have tried to do over the years is help users to install Linux as it is the first step on the journey.When I first started using Linux I had to fall down many holes and I lost many a Windows partition trying to get it installed.I have wanted as much as possible to help other people by showing the steps I have taken to install Linux.The steps continue to change as the years go by and better and better tools come out including the impressive Etcher.This guide is an in depth guide to creating a bootable Ubuntu USB drive.38 Things To Do After Installing UbuntuI initially started this guide for in 2014 and there were 15 items listed. I try to add to the list regularly and update it as th...

Book Review: "How Everything Became War and the Military Became Everything" by Rosa Brooks

Mar 20 12:35pm Das U-Blog by Prashanth
I've recently read How Everything Became War and the Military Became Everything by Rosa Brooks. It's a moderately long book about the institutional culture of the military, the historical and present perceptions of the military and its relationship with peacetime society, the evolving notions of war & peace, and the issues facing the military in today's domestic politics and international uncertainty. The thesis of the book is that while societies have historically tried to neatly separate war & peace spatially as well as temporally, such a dichotomy is rarely clear in practice, and the state of low-grade perpetual war in which the US is currently engaged, especially with regard to the adversaries we face, is in many ways surprisingly similar to the history of wars before the emergence of well-defined nation-states in Europe; moreover, issues like mission creep and a shifting political & financial emphasis away from civilian foreign engagement toward military engagement, in conjunction with adversaries having access to technologies and the fruits of globalization that allow them to attack the US from afar with unprecedented ease, has caused the military to take on roles for which it was not built (in the form in which it exists now), further blurring the lines between civilian versus military roles and war versus peace.I really enjoyed reading this book overall. Although it's a little longer, the writing is clear and accessible, and the stories & anecdotes interwoven with more formal reports & studies make the progression of the book engaging. Additionally, I feel like the author's background of having grown up in an anti-war family and still retaining a somewhat skeptical eye with respect to military action/growth while also having worked in the Pentagon and in similar roles at other institutions for as long as she did lends her credibility when discussing the subtleties & nuances of the US military, its foreign policy, and its institutional culture. Overall, I highly recommend this book to anyone with even a passing interest in current US affairs; follow the jump to see a few other thoughts about this book.Read more »...
