Faill to Pass

You Didn’t Pass Your Certification Exam – Now What?!

Grief

It’s happened to most of us. We have gone through countless hours of studying, training, practicing, learning, etc. We have spent long nights watching videos, reading whitepapers, practicing in labs, and taking practice tests. We thought we had this; we KNEW we had this! But when the test was completed, we hit submit, and we get the dreaded score, which is less than what was required for the Powers That Be to award us our certificate. Four of the seven stages of grief pour over you in rapid fire:

“What went wrong?!”

“I can’t believe I just wasted this money!”

“Maybe if I write to the testing board, they’ll understand that they’re wrong.”

“Ugh, this is so laaaaame!”

But, it’s done. It’s time to take this experience, learn from it, and come back and crush this exam! (more…)

What to Expect When You’re Testing – Best Practices to Prepare for a Red Hat (or Any Other) Exam

Pretty frequently, we get students asking for tips on preparing for Red Hat exams in addition to completing Linux Academy courses and using Hands-on labs. No matter how long you study or how much time you dedicate to preparation, there’s always a lingering “what if?” in the back of your mind. Unfortunately, this is a feeling that will most likely stick with you throughout your career, but you don’t need to let those pre-test jitters get to you. If you study hard and keep your focus, passing your next exam will be a breeze – but studying isn’t the only way to prepare. Here are a few of my own suggestions for making sure that you’re at the top of your game in your next exam.

In this entry for the Linux Academy blog, I have outlined some tips that can really help your LinkedIn profile stand out among the competition!

The Lost Art of Disk Quota Management

Once upon a time, disk space was at a premium (in fact, most compute resources were). Many times, companies and educational institutions provided access to systems via a shell (telnet or SSH) to their employees or students. Since those resources were at a premium, they had to be divided amongst the users in various forms. The most common resource that required strict controls was disk space. Even today, you may need to occasionally limit the disk space (or number of files) that a user account can use. It is one of those system administration functions that is used less often, but it is an important topic to understand (and is one of the objectives on the recently launched LPIC-1: System Administrator – Exam 1 Certification Prep Course here at Linux Academy). Let’s take a look at some of what goes into restricting disk space for your user community. (more…)

Using Personal or Side Projects to Show Experience

One of the most common questions we see here is how to show experience and expertise when you are just starting out or have no professional IT experience. Creating a resume and convincing employers to give you a chance can seem insurmountable when your only job experience is working at the local grocery store or your college bookstore. Even if you do have some professional experience, working towards a promotion or switching to a new field can be incredibly difficult if you are not able to show you have experience with the technologies employers are looking for.

AWS Rekognition

How Old Do I Look?

Most of us use AWS for work, but you can us it for fun too! In this post we are going to look at one of AWS’s Artificial Intelligence (AI) product offering – Rekognition.

Rekognition is a fully-managed service for image analyses. It can detect objects, scenes, and faces in images. You can even catalog the faces and then search through the pictures for the person you are looking for. Amazon uses its vast data store of images (which is why they allow you to save unlimited pictures if you have Prime) to train and improve the processing all the time, and the results are astounding. It can detect emotion, sunglasses, gender and even estimated age range of the person in the photo.

So let’s have some fun: Let’s get the profile photos of the Linux Academy team members and let Rekognition estimate their age. Now, unlike most ‘tech’ companies, we actually have female team members and I know better to bring up the age topic with a lady so we are going to make sure that we do not scan their images. (more…)

AWS Shield

Cloud Compliance – How AWS Shield Plays a Part

In our last article, we took a look at some of the most common compliance regulations that affect IT organizations and their cloud stratagem. Understanding the requirements around compliance can help to inform your cloud infrastructure plans, but is only part of the equation. Today, I want to talk about how the recently announced (AWS re:Invent 2016) AWS Shield can help organizations put some of the complex issues into perspective in a more comprehensive policy. (more…)

Certbot Encryption Image

Getting Started with Let’s Encrypt and SSL Certificates

Movements like HTTPS Everywhere are working to get all sites on HTTPS. Google is one of the major backers of this movement and will eventually mark all regular HTTP sites as insecure by default in their Chrome browser (see more here). It is important that everyone secure their websites so we can all enjoy a safer Internet.

This is where Let’s Encrypt comes in. From https://letsencrypt.org/about/: “Let’s Encrypt is a free, automated, and open certificate authority (CA), run for the public’s benefit. Let’s Encrypt is a service provided by the Internet Security Research Group (ISRG).” This means that anyone can request and receive a free SSL certificate to enable secure HTTP traffic. Now that there is no cost needed to receive a certificate, everyone can and should enable HTTPS on their websites.

This guide walks you through the basics of getting and applying a Let’s Encrypt SSL certificate to an existing web server. It assumes you already have the web server ready and the DNS records set appropriately. Since this is a getting started guide, we will stick with the Certbot recommended by Let’s Encrypt. There are many other solutions or you can even create your own. See here for more information on other clients. (more…)
