The Best Programmers I Know

This blog post describes some of common traits of the the best programmers

• Read the Reference: Don’t go to Stack Overflow. Don’t ask the LLM. Don’t guess. Just go straight to the source. This matches my own experience: the best engineers I know don’t make assumptions—they go directly to the source code or official documentation to understand how things work.
• Know Your Tools Really Well: Great developers understand their tools at a fundamental level. While tools vary from person to person, the most effective engineers master their key bindings, understand the core concepts behind their tools, and continually refine their setup to become more efficient.
• Read The Error Message: Top engineers truly read and try to understand error messages. They form hypotheses, test possible solutions, and iterate systematically. They don’t just react—they think critically.
• Break Down Problems: Strong engineers can take a vague, complex problem and break it down into manageable pieces. They create clear execution plans and know how to make steady, incremental progress.
• Don’t Be Afraid To Get Your Hands Dirty: Strong engineers don’t just think or talk from first principles—they build. If they have an idea, they’re quick to put together a proof of concept to bring it to life and demonstrate their thinking in code.
• Always Help Others: Strong engineers are force multipliers. They share their knowledge, model sound decision-making, and raise the bar for the entire team. Others naturally look to them as examples.
• Write: Strong engineers are well articulate and can write down their ideas and evangelize them well. They don't look down on communication being a soft skill, they see it as a craft and improve it.
• Never Stop Learning: Strong Engineers stay curious and continuously explore new tools and ideas, regardless of age or experience.
• Status Don't Matter: Strong engineers learn from everyone, regardless of title or experience. There is no hierarchy when exploring and tapping into curiosity.
• Build a Reputation: Strong engineers make lasting impact through open source, critical projects, public speaking, or writing, and they build a reputation of excellence for their work and their teams.
• Have Patience: To be one of the best, you need an incredible amount of patience, focus, and dedication. You can’t afford to get distracted easily if you want to solve hard problems.
• Never Blame the Computer: If there's something that you can't figure out, it's you, not the computers. The best keep digging until they find the reason.
• Don’t Be Afraid to Say “I Don’t Know”: Say “I don’t know” confidently. It’s the first step toward real learning.
• Don't Guess: In the face of uncertainty, investigate instead of making assumptions.
• Keep It Simple: Strive for simplicity and clarity in code. Avoid cleverness for its own sake.

Here are some of the noteworthy interviews that I have watched:

Interview with the Author of Dopamine Nation

An interview with Dr. Anna Lembke, a leading expert on dopamine and addiction, explores how this neurotransmitter is fundamental to motivation and survival. Dr. Lembke uses the pleasure-pain balance analogy to explain how constant exposure to high-dopamine stimuli in modern life can shift our baseline towards pain, driving addictive behavior as we seek to restore balance. The discussion touches on various forms of addiction, including to substances, behaviors, and even digital media, highlighting the impact of early exposure and the difficulty of recovery.

Some highlights:

• What is Dophamine? One of dopamine's most important functions is helping us experience pleasure, reward, and motivation. Dopamine is described as a fundamental "survival chemical" that tells us something is something we should approach, explore, or investigate. Dopamine is neither good nor bad; it's a signal that tells us whether something is potentially useful for our survival and is related to what we predicted about how rewarding or pleasurable something would be.
• Pleasure-Pain Balance: One of the most important findings in neuroscience in the past 75 years is that the same parts of the brain that process pleasure also process pain. These two experiences work like opposite sides of a balance. Dopamine plays a role in this balance, providing information about where we are in that relativity scale between Pleasure and Pain. The Brain's Goal is Homeostasis. Brain wants to remain level between pleasure and pain. Restoring homeostasis is one of the overarching physiological drives for all living organisms, crucial for adaptive and healthy states of being.
  • When we engage in a pleasurable or rewarding activity, such as consuming alcohol or engaging in behaviors like using social media, pornography, or even certain types of work, it releases dopamine in the brain's reward pathway.
  • This dopamine release presses down on the pleasure side of the balance, tilting it upwards on the pain side. No sooner does the balance tilt towards pleasure than the brain begins to work hard to compensate and restore a level balance.
  • This neuroadaptation involves mechanisms like down-regulating dopamine transmission, for instance, by involuting (taking inside the neuron) post-synaptic dopamine receptors – metaphorically described as removing the docking station where dopamine binds.
  • A crucial aspect of this neuroadaptation is that the brain's compensation often overshoots. The "Gremlins" don't stop when the balance is level; they stay on until it's tilted an equal and opposite amount to the side of pain.
• Addiction: From an evolutionary perspective, this overshoot was potentially adaptive in a world of scarcity, making organisms relentless seekers by driving them to alleviate the pain/deficit state. However, in the modern world of overwhelming abundance and easy access to highly potent ("drug-ified") reinforcing substances and behaviors, this ancient wiring is mismatched. Repeatedly stimulating the reward pathway with strong pleasure signals causes the brain's compensation to become persistent. The "Gremlins on the pain side of the balance end up camped out there. This leads to the addicted state, where the hedonic set point shifts to the side of pain. The individual now needs more and more of the substance or behavior, in more potent forms, not to feel high or good, but just to level the balance and feel normal.
• Understand Dopamine Improves Life: an optimal way to live, as discussed in the sources, is not about constant happiness or comfort. Instead, it involves understanding the biological underpinnings of reward and pain, consciously choosing to engage in activities that require effort and discomfort for a healthier, sustained dopamine response, being present in the moment, accepting difficult emotions, taking personal responsibility, strategically limiting access to highly stimulating but ultimately detrimental rewards, and being mindful of how the modern world exploits our reward system.
