Learning Without Thinking Is Labour Lost; Thinking Without Learning Is Perilous You cannot grow by just collecting information. You also cannot solve real problems by only relying on your own mind. Confucius nailed this balance over 2,500 years ago and it’s more relevant now than ever. Learning without thinking is labour lost You absorb facts, complete courses, read articles. But if you never pause to ask why , how , or so what? , you waste your effort. Passive consumption builds no real skill. You finish a cybersecurity module but never test the concepts in your network. You read about project management but don’t reflect on your last failed deadline. Without reflection, learning stays shallow. You forget it fast or apply it wrong. Thinking without learning is perilous You trust your gut, debate ideas, form strong opinions, but without grounding in evidence or experience, you risk error, bias, or irrelevance. You design a system based on assumptions, n...

Obedience Is Not Optional, It’s Everything Your mom says, “Wash the dishes.” You sweep the floor, clean your room, make the bed, and cut the lawn but the dishes sit untouched. Did you obey? No. You did good things. Helpful things. Maybe even harder things. But you didn’t do what was asked . This simple truth mirrors a deeper spiritual reality: obedience to God is not replaceable by other good works no matter how sincere, sacrificial, or impressive they seem. God doesn’t need your extras when He’s clearly asked for something specific. He wants your obedience. What Scripture Says 1 Samuel 15:22 (ESV) “Has the Lord as great delight in burnt offerings and sacrifices, as in obeying the voice of the Lord? Behold, to obey is better than sacrifice, and to listen than the fat of rams.” King Saul thought offering extra sacrifices would cover his disobedience. God rejected it. Obedience > religious effort. John 14:15 (ESV) “If you love m...

💡 The Complete Fix: CML VT-x/EPT Error Solved 🛠️ I battled the persistent error: "Virtualized Intel VT-x/EPT is not supported on this platform" while installing CML (Cisco Modeling Labs) on VMware. This problem occurs because the Windows host locks the CPU's hardware virtualization features (VT-x/EPT) that CML needs to run its internal network nodes. I discovered that fixing this requires aggressively disabling Virtualization-based security (VBS) and HVCI across multiple system layers. Here is the definitive, comprehensive guide covering every step necessary to solve this issue. Step 1: The Quick Fix (Disable Nested VT-x in VMware) I found that telling VMware to hide the feature initially allowed the CML VM to boot, but it failed later when trying to run network nodes. This must be reversed later, but it is an important diagnostic step. Power off the CML VM. Go to Settings → Processors . Ensure the box for Virtualize Intel ...

Last year, as we prepared to celebrate 50 years of independence, I wrote a reflection titled “Reflecting on 50 Years of Independence: A Call to Action for Papua New Guinea.” In that piece, I laid out five major challenges that continue to hold us back: human nature, governance, economic struggles, social attitudes, and political influence. I ended with a message of hope—that if we faced these issues honestly and acted decisively, we could unlock our true potential as a nation. Now, one year on, the milestone has passed. The celebrations have come and gone. But when the dust settles, we are left with the same uncomfortable truth: instead of changing course, we continue to run ourselves into the ground while uniting to put the wrong people in charge. From Reflection to Repetition The problems are not new. We know them well: lack of respect among citizens, self-interest over national interest, entitlement without effort, and leaders who operate with little to no accountability. ...

Antennas serve as crucial transitional structures between guided electromagnetic energy (like in transmission lines) and the free space through which radio waves propagate [1, 2]. Understanding how they radiate energy is fundamental to antenna theory, and two key concepts in this understanding are **radiation patterns** and **directivity**. Radiation Patterns An **antenna radiation pattern**, also known as an **antenna pattern**, is defined as a **mathematical function or a graphical representation of the radiation properties of the antenna as a function of space coordinates** [3]. These properties are typically determined in the **far-field region** and are represented based on **directional coordinates** [3]. The radiation properties of concern include **power flux density, radiation intensity, field strength, directivity, phase, or polarisation** [3]. The radiation pattern primarily describes the **two- or three-dimensional spatial distribution of radi...

Building upon our discussion of fundamental antenna characteristics, we now turn our attention to some of the most common and basic antenna types: wire antennas  and loop antennas . These forms are significant due to their simplicity, versatility, and widespread use in various applications. Wire Antennas Wire antennas are familiar to many and are seen in numerous places such as on vehicles, buildings, and aircraft. They come in various shapes, including straight wires (dipoles), loops, and helices . Linear or curved wire antennas are some of the oldest, simplest, cheapest, and often the most versatile. The simplest form is a straight wire , commonly referred to as a dipole . Dipoles are discussed in more detail in Chapter 4 of Balanis' "Antenna Theory".  Variations of the straight wire include monopoles , often used for mobile cell and cordless telephones, sometimes in a helical form with a plastic cover to increase input resistance for ...
