Article #3 - No procrastinating. Post by January 28th

Post a reply below. 

To start us off, this article is about how to change something relatively simple in Ubuntu.  That is the login screen.  It is PURPLE.  Maybe you have customized the background etc... But you want to change the login screen.  I set mine to be a color.  Plain black.  The hex code for that is #000000
You can also use an image, that is a bit more complicated, but would be a good challenge for some of you.  If this article doesn't meet your needs just Google.  "How to change the login screen in Ubuntu 18.10" or 18.04

There used to be an option in one of the distros (I think it was Mint) --- right out of the box you could right click on a file and choose to edit it as administrator.  This was pretty handy for editing config files.  The standard way of doing it is to either launch the editor program - commonly gedit in Ubuntu and now xed in Mint -  using the sudo command.  Then you can open your file by browsing to it with the file menu.  Alternatively you could launch gedit along with an absolute path statement.  The other option is to launch the file manager with sudo.  sudo nautilus

For beginners this is frustrating since you have to know the names of the programs you want to launch, but it does keep newbies from accidentally editing a system file, which is probably why they got rid of the right click menu.  Now, at this point if we know the difference and how not to mess stuff up, I think the right click option is pretty handy.

Wine helps Linux users use Windows applications on a Linux based distribution. Wine 4.0 update was recently released on January 22. The update includes Game-Controller support, Vulkan Support, and patches to the program. More than 6,000 changes were found in the update. This is a way that linux can start to compete with Windows as one of the top operating systems

Last year Google released a feature allowing people to run desktop Linux apps on Chrome OS. Now they might be planning to let Chromebook owners to choose a Linux distro to run on instead of using Chrome OS. Right now it's unsure if the distro being downloaded for the Chromebook would have to be modified to work alongside Chrome OS. https://www.omgubuntu.co.uk/2019/01/chromebook-linux-apps-choose-distro

This article reflects on the strides made in the Linux world in 2018, and talks about where Linux is headed in the future.  The article covers Ubuntu's deviation from Unity and switch to Gnome.  It also covers Steam bringing Windows games over to Linux, and how they seem to be in it for the long haul and not just a quick money grab. They discuss the implications of IBM acquiring Red Hat to compete with Windows in the server world.

Processor Affinity or also referred to as CPU pinning is a way to designate a custom core count to a given process.  In other words, if you have a 4 core processor you can set a program like Handbrake to use only 2 of the cores. This could potentially make multitasking a more viable option by dividing up and designating certain CPU cores to programs of your choosing. This article focuses on how to set processor affinity within Linux using the command line.

This article is about reasons why Linux is more secure than Windows. It starts by talking about how updating windows takes up so many system resources so a lot of people turn it off and miss critical security updates. Also as we discussed in class the popularity of windows makes it a more attractive target for criminals to design malware programs for it.

This article is about making Gallium-OS into a Chromebook specific Linux variant. Gallium-OS is based on Xubuntu.  Gallium-OS isn't a great solution it requires the person to make adjustments inside the hardware and firmware. This is for people who don't want to use Chrome-OS and want to run a complete Linux distro.

Re: Article #3 - No procrastinating. Post by January 28th

So this week I found this article on "8 tips to help non-techies move to Linux". The first couple thing the article talks about is just talking to a person without bringing my expectations of what a I believe their computer or lap should be like, and what distribution of Linux they feel comfortable using. The article then talks about how much time you should give to them before you allow them to figure some things out on there own. Not abandoning them completely but also not being there for every little problem. 

Thank You

Article describes some of the more popular security distributions for linux, and lists some of their pros and cons. The top 3 were Tails, Kali, and Qubes. I had never heard of Qubes before; the article says it runs all of it's applications in virtual machines. So if one was to get infected, the chances of the host system getting infected are greatly reduced. Tails is more for privacy focused people, as it includes cryptographic tools, and routes all traffic through the Tor network. Kali is a penetration testing distribution that comes pre loaded with an arsenal of tools to test network defenses, but it also includes software to configure a VPN and proxies out of the box.
