Blog postWe’re all hearing a lot about how important it is to protect our personal data. But just what is personal data? This article comes from my Wiley/Sybex Linux Security Fundamentals book – which happens to be about much more than just Linux.
Your personal data is any information that relates to your health, employment, banking activities, close relationships, and interactions with government agencies. In most cases, you should have the legal right to expect that such information remains -
Blog postSometimes it can be somehow comforting to reflect on how much worse everything is now than it was in the good old days.
“Kids have no respect.”
“Everything costs way too much.”
“Public officials don’t inspire trust.”
“And what about the weather? We never used to get so many devastating hurricanes, did we?”
Well I’m old enough to have been around the block a few times and I’m not sure. I wasn’t exactly angelic as a child, things always&nbs -
Blog postIn this article, I’ll share some newbie explorations I’ve made in the areas of data analytics and pro hockey.
I recently embarked on a crazy journey into the world of data analytics. There’s nothing all that crazy about data analytics, mind you. It’s my journey that’s a bit odd.
You see, I’ve built myself a nice career in cloud and Linux administration, but I’m no developer. And, besides some obvious overlap, data is a whole universe apart from administration – a universe -
Blog postEarly one recent morning my Linux workstation failed to boot. And just like that, all my work plans for the day ground to an immediate halt.
This was the Linux workstation that was host to thirty years-worth of data: The original working drafts of all my books. The master versions of my course videos. My tax records, banking information, password vault, and the access keys to my cloud infrastructure.
Was I surprised? Not particularly. The day before I’d been struggling with a -
Blog postCurious about what kinds of personal and even private data you may be exposing through the course of a normal day on the internet? How about using “all kinds” as a starting point?
Here, adapted from my new book, Keeping Up: Backgrounders to all the big technology trends you can’t afford to ignore, is a way to break down the scope and nature of the problem by platform.
Financial transactions Take a moment to visualize what’s involved in a simple online credit card purchase -
Blog postYou know the old joke: there are two kinds of companies, those that’ve been hit with an IT disaster, and those who don’t yet realize they’ve been hit with an IT disaster.
But what they all have in common is that there are plenty more disasters to come. So ask yourself whether you’re ready for the next one.
This article, which is based on my Pluralsight course, Linux System Maintenance and Troubleshooting, is intended to start you thinking about what building an effective -
Blog postA local area network (LAN) is really nothing more than a structure for organizing and protecting network communications for all the devices running within a single home or office.
Let me break that down a bit. When I say, within a single home or office, I mean all the devices that are connected through either a physical or wireless connection to a network router. That router might be a WiFi access point or the modem your internet service provider (ISP) gave you.

Blog postA big part of administrating Linux machines – especially remote machines – is managing and installing software.
When something goes wrong with a local application or when something on the file system breaks and needs fixing, you’re often going to want to push updates without having to travel many miles to sit down in front of a physical screen.
A lot of problems can be solved through Bash scripts, of course, but there are still plenty of use-cases where there’s no alternative -
Blog postStaring at a plain, dumb command line prompt with no clue what to do with the AWS CLI next can be a humbling experience. And, in my experience at least, staring at the Management Console for AWS CloudFormation can be worse.
So let me offer you some quick “getting started” help based on part of the content in my latest Pluralsight course.
First of all, if you’re planning to manage your CloudFormation stacks through the AWS CLI rather than the Management Console, I discuss -
Blog postHow to get exactly the account and environment information you need to manage your AWS account using just the AWS CLI
Installing the AWS CLI is actually quite simple. The best way to get it done is to head over to the AWS installation guide and follow instructions for your OS.
Right now they’re pushing us towards version 2 of the CLI and I haven’t seen any reason not to go along. I’m working with Linux so that’s where I’d head next.
To get it done, I’ll paste
