Have you EVER heard of or used the tac command?

jarrelrivera
I've never used the tac command. I know it, just never used it.

The common commands I use for viewing the contents of a file are cat, less, more, head, tail, nano and vim. All of the commands I've mentioned are in the exam objectives for Linux+. I'm not sure about tac.

grep is a command that is very common in many of the CompTIA exams whether, it'd be for Linux+, Security+, CySA+, Pentest+ and even SecurityX (formerly CASP+). I personally use grep in many scripts.

aside from grep, I also suggest knowing sed and awk

Amazing session for the new Linux+ v.8 (006) exam TTT session today 9/11/2025.

Jason went over the tac command and many other options. I'm not even embarrassed to say I have never used the tac command or searched in files with grep. Excellent and eye opening session. I truly and completely appreciate going back to the roots and fundamentals. One thing I will say about Linux I truly love and enjoy. You never stop learning!

Linux+ Train the Trainer session 2025-09-09

Shea Bennett
Oracle Virtualbox is easier to use and the load is lighter than Hyper-V. When I setup my classes, I'm using native Linux to really deep dive for real world ops. We don't have any Hyper-V in any of our datacenters. Only AWS/GCP Cloud, RHEL/Rocky Linux, Oracle Linux and VMware, OpenStack or Proxmox. So, unless your a primarily Windows shop. I wouldn't use it.

Hyper-V is a Type 1 (bare-metal) hypervisor that comes with Windows Pro and higher editions (though it can be installed on Home if you look up how). Being Type 1 means Hyper-V runs directly on the hardware, with a lightweight virtualization layer in between. This allows near-native performance.

In contrast, Oracle VirtualBox is a Type 2 (hosted) hypervisor by default—it runs as a regular application on top of Windows. As a result, all VM hardware access must go through the Windows OS first, which adds overhead and reduces performance compared to Type 1 hypervisors.

So, in general, Hyper-V is faster than VirtualBox by default.

However, there’s a neat trick: if you have both Hyper-V and VirtualBox installed, you can configure VirtualBox to use Hyper-V as its backend. To do this:
  1. Open the settings for your VirtualBox VM,
  2. Go to System > Acceleration,
  3. Set Paravirtualization Interface to Hyper-V.
This allows VirtualBox to leverage Hyper-V’s performance benefits while maintaining VirtualBox’s compatibility and features.

Why is this useful? In cybersecurity, many pre-built VM targets and OS images are packaged specifically for VirtualBox. So for students taking a cybersecurity course, it makes sense to use VirtualBox—but enabling Hyper-V paravirtualization gives the best of both worlds: broad compatibility and improved performance.

If you're not teaching a cybersecurity course, however, it makes sense to have a simpler setup where you just stick with Hyper-V for faster, cleaner VM performance on Windows.

I teach numerous cybersecurity and digital forensics courses, which means I often use Kali and Parrot (as discussed in the training), and occasionally CSI Linux. I will try the "Set Paravirtualization Interface to Hyper-V" before the class tonight and do a few labs to see. Thanks.

Overall, I like them both. I've used both and both are great platforms for different reasons. Also, KVM is a good tool for long-term virtualization projects.

For the labs, I chose to do them on Oracle VB. My students or clients are not always on Windows Host OS

How AI and Large Language Models (LLMs) Are Shaping the Future of Data with CompTIA Data+

sharma_sid
We all know data is the backbone of every modern business. But with data growing faster than ever, making sense of it all can feel overwhelming. That’s where Large Language Models (LLMs) like ChatGPT come into play — they’re not just tech buzzwords, they’re game-changers.

💡 If you’re preparing for the CompTIA Data+ certification or working in data roles, combining your data skills with LLM-powered tools can take your career to the next level.

Here’s how LLMs help in the data world:​


  • ✅ Turn everyday questions into structured data insights — just ask in plain English and get answers.
  • ✅ Generate clean, easy-to-understand reports in a flash.
  • ✅ Get smart suggestions for fixing messy or incomplete data.
  • ✅ Automatically help with data governance and compliance tasks.

The future is already here. Companies are moving beyond spreadsheets and dashboards — they’re using AI to speed up data analysis and make smarter decisions faster.

If you combine the solid foundation of CompTIA Data+ skills with the power of LLMs, you’ll not only pass the exam but be ready for real-world challenges.
The demand for data pros who can work with AI is only going to grow. So, why wait? Let’s make data easier, smarter, and more human.
