Fun Linux Things

CIO Musings

For me there was, and is, a fascination with using free tools on inexpensive hardware to do impressive things. Unix has become Linux, and it is running on an amazing variety of devices. New lineages of Linux have emerged.Some are highly specialized, some are more generic. I run Linux on a half dozen platforms at home. A quick google search revealed not one, but several Linux distros that will run on this unit. Unix has always fascinated me.

Where are my Linux devices?

IT Toolbox

Continuing on with the dissection of the anatomy of Linux you may remember that I rambled on a bit about how the kernel modules are used to access the various hardware devices on the computer. Not just hardware either. This makes the Linux kernel soOther things like file systems, networking protocols and lower level stuff (real technical term there :) ) can be and are handled by kernel modules.

Linux vs Unix Hot Patching – Have We Reached The Tipping Point?

Forrester IT

The Background - Linux as a Fast Follower and the Need for Hot Patching. No doubt about it, Linux has made impressive strides in the last 15 years, gaining many features previously associated with high-end proprietary Unix as it made the transition from small system plaything to core enterprise processing resource and the engine of the extended web as we know it.

Anatomy of a Linux distribution 3

I mentioned in the previous ramblings before about a special file called initram or similar which supports the Linux kernel and is a small operating system in itself. In the earlier days of Linux when the kernel was much simpler and the hardware it ran on was very limited this initram file was not needed.

Easy-to-exploit rooting flaw puts Linux computers at risk

Network World

The maintainers of Linux distributions are rushing to patch a privilege escalation vulnerability that's already being exploited in the wild and poses a serious risk to servers, desktops and other devices that run the OS. The vulnerability, tracked as CVE-2016-5195, has existed in the Linux kernel for the past nine years. This means that many kernel versions that are used in a variety of computers, servers, routers, embedded devices and hardware appliances are affected.

Anyone who had followed me for any length of time knows that I love Linux. I love it because of the power it give me over my hardware and I love it because the Linux I use is mine and mine alone and not some platform where I have no control over how it works and only have the right to use. I am not going into the licensing just yet as I am just going to talk about Linux distributions.

Review: Dell Latitude E7370

Scott Lowe

As part of my Linux migration (see my initial progress report ), late this past week I started setting up my first non-Apple laptop since 2003. From a Titanium PowerBook G4 to multiple generations of aluminum MacBook Pros to (finally) a MacBook Air, I’m familiar with the quality and reliability of Apple hardware. Finally, with regard to my Linux migration, I’m happy to say that Fedora 25 runs flawlessly on the E7370, with everything working as expected out of the box.
