Don’t jump to the solution

“A problem well stated is a problem half solved.”
— Charles Kettering

One of the most valuable skills an engineer can develop is also one of the least discussed: the ability to properly define a problem before attempting to solve it.

Yet this is precisely where many debugging efforts begin to go wrong.

The moment a system fails, the natural instinct is to take action. A driver isn’t loading. A process is crashing. A network connection is dropping. The pressure to restore normalcy creates an overwhelming urge to start changing things immediately. Logs are scanned, configurations are modified, patches are applied, and commands are executed—all in the hope that one of them will magically make the problem disappear.

Unfortunately, urgency often becomes the enemy of understanding.

A fix applied to a problem that has not yet been understood rarely solves anything. More often, it simply moves the issue elsewhere, disguises the symptoms temporarily, or introduces a new set of complications that surface later. Many engineers discover, sometimes after hours or days of effort, that they have spent more time chasing assumptions than investigating facts.

What separates experienced engineers from everyone else is not necessarily their ability to arrive at solutions faster. In many cases, it is their willingness to slow down at the beginning. They understand that a problem is not an emergency to be suppressed but an investigation to be conducted.

This distinction is subtle but important.

When we treat a problem as an emergency, our attention immediately shifts toward finding a remedy. We begin asking, “What should I do?” before asking, “What exactly is happening?” The consequence is that we start building solutions around symptoms rather than causes. A kernel panic becomes the problem. A failed connection becomes the problem. A boot failure becomes the problem.

In reality, these are merely observations. They are evidence. They are clues pointing toward the actual problem, not the problem itself.

The first responsibility of an engineer is therefore not to fix but to understand.

A surprisingly effective technique is to force yourself to describe the problem in one plain sentence before touching anything. Not a paragraph. Not a theory. Not a suspected root cause. Just a factual statement describing what is being observed.

This simple exercise creates clarity. It forces you to separate what you know from what you believe. It helps eliminate assumptions that often sneak into the investigation without being noticed. More importantly, it creates a shared understanding when discussing the issue with colleagues or team members.

Many difficult debugging sessions become dramatically easier once the problem has been clearly articulated. The act of defining the problem frequently reveals gaps in understanding that would otherwise remain hidden beneath layers of speculation.

Another trap engineers frequently fall into is becoming attached to the first explanation that comes to mind. Human beings naturally look for patterns. If a symptom resembles something we encountered in the past, we immediately assume the same cause is responsible. While experience is valuable, it can also create bias. Once a theory takes hold, every piece of evidence begins to get interpreted through that lens, even when the facts suggest otherwise.

Experienced engineers are careful not to fall in love with their first hypothesis. They gather evidence patiently. They challenge their own assumptions. They allow the system to reveal the answer rather than attempting to force the answer onto the system.

This mindset becomes increasingly important as systems grow more complex. Modern Linux-based products, embedded systems, distributed applications, and AI-enabled devices contain layers of software and hardware interacting in ways that are often difficult to predict. In such environments, guessing becomes expensive. A disciplined investigative approach becomes essential.

The engineers who consistently solve difficult problems are rarely the ones who rush toward solutions. They are the ones who spend time understanding the terrain before taking a step. They know that a few minutes invested in framing the problem correctly can save hours of wandering in the wrong direction.

In an industry that celebrates speed, there is tremendous value in learning when to slow down. Before reaching for the keyboard, before searching for fixes, and before implementing changes, take a moment to ask a simple question:

“Can I clearly state the problem?”

If the answer is no, the investigation has not yet begun.

And as Charles Kettering wisely observed, a problem well stated is already halfway solved.

AI Writes the Code. You Make It Work.

The software industry is witnessing one of its biggest transformations. AI can now generate functions, classes, scripts, and even entire applications in seconds. Tasks that once took hours can now be completed with a prompt.

But there is one thing AI cannot do reliably:

Make complex systems work.

As AI lowers the barrier to writing code, the value of simply knowing syntax or frameworks is diminishing. The real differentiator is no longer the ability to produce code—it’s the ability to understand, design, integrate, troubleshoot, and optimize systems.

When a production system crashes, a device fails to boot, network throughput drops unexpectedly, or an AI application behaves unpredictably, the challenge isn’t writing more code. The challenge is understanding what is happening beneath the surface.

work is becoming a premium skill.

This is where deeper skills become invaluable:

  • Systems thinking

  • Software architecture and design

  • Linux internals

  • Embedded systems knowledge

  • Debugging and root cause analysis

  • Performance optimization

  • Hardware-software interaction

  • Problem-solving under uncertainty

AI can suggest solutions. It can generate implementations. But it cannot replace the engineer who understands the system well enough to determine whether those solutions are correct.

The future belongs to engineers who go beyond coding and develop a deep understanding of how technology actually works. As code generation becomes easier, expertise becomes rarer—and therefore more valuable.

In the age of AI, writing code is becoming a commodity. Making systems work is becoming a premium skill.

AI is Moving to the Edge. The Edge Runs Embedded Linux.

Every day there is a new AI model, a new tool, a new framework, or a new company promising to automate yet another piece of work.

Many engineers are watching this happen and asking themselves a difficult question:

“Will AI replace me?”

I think that’s the wrong question.

A better question is:

“As AI automates more things, which skills become more valuable?”

Let’s look at where AI is headed.

AI on the Edge
For years, AI lived primarily in the cloud. You sent data to a server somewhere in the world, it processed it, and sent a response back. But that’s changing. The next wave of AI is moving to the edge. 

Your car cannot wait for a cloud response before applying the brakes. A robot cannot depend on an internet connection to make decisions. An industrial machine cannot stop production because a cloud service is unavailable.

The future of AI requires decisions to be made locally, on the device itself. And that’s exactly why AI is moving to the edge.

Now comes the interesting part.

What powers most of these edge devices?

Not AI. Embedded Linux it is.

Whether it’s automotive systems, industrial automation, networking equipment, robotics, smart cameras, medical devices, or IoT gateways, there is a very high chance that Embedded Linux is sitting underneath.

The AI application gets all the attention. The Linux platform quietly does all the heavy lifting.

  • The boot process.
  • The drivers.
  • The networking stack.
  • The memory management.
  • The communication with hardware.
  • The performance optimization.
  • The debugging.
  • The reliability.

Without these layers, AI is just another application that cannot run. And this is where a fascinating pattern emerges.

Business-end of your skills
As technology becomes more automated, fewer engineers understand what is happening underneath. Twenty years ago, many engineers understood operating systems and system internals. Today, most engineers are trained to use frameworks. Tomorrow, many may simply use AI.

But when something breaks, somebody still has to understand the layers beneath.

  • When the WiFi driver crashes.
  • When the system randomly hangs.
  • When memory usage grows uncontrollably.
  • When boot time exceeds the target.
  • When hardware refuses to initialize.
  • When the AI accelerator is underperforming.

The solution isn’t found in a prompt. The solution comes from engineers who understand the platform. This creates what I call the Automation Paradox.

The higher the automation, the rarer the engineers who understand the layer beneath it.

And rarity creates value. Thousands of engineers can use AI tools  only fewer can debug a Linux driver. Thousands can deploy applications only fewer can bring up a new hardware platform from scratch. Thousands can consume technology only fewer can build the foundation that technology depends on.

The industry is not struggling to find people who can use tools, it is struggling to find people who can solve problems. The kind of problems that stop products from shipping.

This is precisely why Embedded Linux continues to remain one of the most valuable skills in the industry.

If you’re looking for skills that will remain relevant even as automation grows, don’t just learn how to use the latest tools, learn the layer beneath them. Because the future will always need engineers who understand how the system really works.

Be one of them.
