37 INSANE Linux Commands you NEED to Know in 2025

Communicating - Paul W Smith

 

I know you think you understand what you thought I said, but what you heard is not what I meant.

This phrase, sometimes attributed to former Fed Chairman Alan Greenspan, nicely captures the problem we often have in communicating. Getting our ideas across to another goes far beyond just articulating them clearly - it involves a subtle combination of body language, volume, emphasis, cadence and inflection. It benefits tremendously from continuous feedback. As text messaging and social media become more frequent communication channels, it’s easy to see how we might have trouble understanding one another.

When my wife and I travel internationally, we try our best to learn a few basic phrases in the local language. At the very least, it’s a polite way of acknowledging that we are on their turf. It is usually met with a genuine effort to find some common ground for exchanging information. I am embarrassed by the number of people around the world who speak functional English, while my foreign language skills are minimal at best. In these conversations, facial expressions and gestures are a critical element of success. This approach, however, isn’t always enough.

Recently, we were in Budapest and my attempts to learn a few words in the Hungarian language were a complete failure. When a store clerk, who had just been speaking fluent Hungarian to his colleague, thanked me for my purchase in nearly perfect English, I asked him to teach me to say “Thank you” in Hungarian. After about 5 attempts, I gave up, apologized, and walked away in defeat. Several days of study and practice later, I tried out my new language skill on a local tour guide (who BTW also spoke excellent English). “Köszönöm,” I said. After giving me a quizzical look, she finally replied “I think you are trying to say, “Thank you”?

Sensing my frustration, she added that Hungarian is considered one of the most challenging languages to learn. While she didn’t say how long it had taken her to learn English, she did point out that there are many different dialects in the US, making it difficult when speaking with tourists from different regions. But even when speaking the same language with someone from the same region, we still find it difficult to communicate. As if that isn’t enough, even those troublesome dialects shift with time.

If you are a “Swiftie”, you will recognize the picture above. If not, you do now. Tay-Tay fans will also know that she began her career at age 15 when she signed a deal with Big Machine Records. At the age of 16, she played a concert ($20/ticket) at Athens Drive High School to an audience of about 150 students. Whether you're a Swiftie or not, you've likely heard about her recent Eras Tour, which began at State Farm Stadium in Glendale, Arizona. The sold-out stadium held 69,000 people. The average ticket price for the Eras tour was $1600.

According to speech scientists, more than just Ms. Swift’s artistry, fame, and bank account have changed. Researchers Miski Mohammed and Matthew Winn at the University of Minnesota have studied years of interviews with Taylor Swift to trace the evolution of regional and socio-cultural dialects. Taylor is a very public figure, and her numerous media appearances spread over a 20-year year career provide an exceptional opportunity to chronicle dialect change for an extended period of time. Mohammed and Winn’s results were recently published in The Journal of the Acoustic Society of America.

Acoustical measurements and analysis captured changes in accent from her country phase in Nashville, through her transitional period in Philadelphia, to her New York pop era. Her Southern indicators faded as she moved to Philadelphia and New York, with her pronunciation even showing signs of hyper-correction from the preceding dialect. The change was accompanied by lowered pitch associated with authority and confidence. This was a time when Taylor was becoming more outspoken on social issues. In summary, the study suggests that speech patterns and accents are determined by a combination of geographical location, social dynamics and personal development.

Traveling in foreign countries has helped me to appreciate just how much I take communicating for granted. Learning a few words in the local language can help, but “köszönöm” won’t get you very far. It’s easy to take communication for granted here in the US, but even a common language has it’s pitfalls. Effective communication involves more than just words - it involves tone, body language and feedback. Even when speaking the same language, varying dialects and accents complicate communication. Taylor Swift’s evolving speech patterns, studied in depth by researchers, demonstrate how geographical location, social dynamics, and personal growth influence dialect change.

If we ever hope to understand what others say and mean, it’s clear that email, text messaging, teleconferencing (with postage stamp sized head shots) and other social media channels are not the answer.

Wireshark, Kali and nmap exercise

 I get quite a few emails of people asking me for troubleshooting tips and tricks as well as assistance with problems.

I wish I had a dollar every time I suggest people get familiar with their tools, play with them, and determine their limitations with specific tools. You wouldn’t troubleshoot a cabling issue with Wireshark, would you?

What would you think about a baseball player not going to the batting cage and expecting to play in the major leagues, or a hockey player who refuses to go to hockey boot camp or practice.

The funniest thing, is that you do not need a fancy lab and a lot of equipment for your exercises or to practice.  You can take most tasks that you do every day and turn it into an exercise. 

Here are some examples that I perform almost daily to keep my skills relatively sharp.:

-          just start a Wireshark capture

-          review a trace

-          ping something, trace route while capturing

-          look at my ARP table in Windows or Linux

In this video, I use Kali Linux and Wireshark and nmap to illustrate an example of a simple exercise you can perform as well.

A Breath of Fresh Air Why Blowing Out Dust Keeps Your Computer Alive Longer

Dust may seem harmless, but inside your computer, it’s a silent killer. Over time, tiny particles build up around fans, vents, and heat sinks, trapping heat and forcing components to work harder. This extra stress can lead to slower performance, random shutdowns, and even permanent hardware damage. Regularly blowing out dust from your computer prevents this buildup and helps keep your system running smoothly and quietly.

Clean airflow is one of the most important factors for maintaining ideal operating temperatures. When dust clogs the cooling system, heat lingers longer inside your case, shortening the lifespan of components like the CPU, GPU, and power supply. By using compressed air or an electric air duster, you can easily clear out debris from fans, radiators, and filters. This simple habit often results in noticeably better performance, lower fan noise, and fewer overheating issues — all without spending a dime on upgrades.

Beyond performance, cleaning your PC also contributes to better stability and energy efficiency. When components stay cool, they consume less power and run more consistently, reducing the chance of crashes or throttling during heavy workloads. For gamers, IT pros, and creative professionals alike, this means smoother frame rates, faster rendering, and longer hardware life.

Finally, dusting out your computer is quick, cheap, and surprisingly satisfying. It’s one of the easiest forms of preventive maintenance you can do — no technical skill required. A few blasts of air every couple of months can save you hundreds in future repairs or replacements. So the next time you notice your fans sounding like jet engines, grab that can of air and give your machine the breath of fresh air it deserves.
