Developer Tea

This episode focuses on the critical importance of having a backup plan, not just for technical redundancies but especially for situations involving human error, which are highly prevalent in one's career. The core argument hinges on understanding risk and reward curves, highlighting the disproportionate impact of failures compared to incremental successes.Understanding Risk and Reward Curves:Successes are often incremental. Delivering a project on time typically leads to opportunities for more projects, good performance reviews, and modest pay increases (e.g., 5-7%). These are positive, but linear or slightly bumpy gains.Failures, especially uncaught ones, have a much longer negative tail. The potential for loss from a significant mistake or a disastrous project significantly outweighs the potential for gain from a success.A bad performance review, for example, can affect future reviews, decrease promotion likelihood, and follow you for a much longer period than a good one.Uncaught failures can place individ

Todays episode delves into understanding and leveraging second and third-order consequences – the ripple effects that occur after an initial action – and introduces forcing functions, which are an inverted way of thinking about these consequences, designed to drive desired outcomes by first determining "what must be true" for them to occur. The episode also connects these concepts to the importance of effective goal setting, explaining how well-defined goals provide clarity, focus, and a strategic framework for decision-making and career advancement.Grasp Second and Third-Order Consequences: Learn to identify the downstream effects of initial actions. For instance, setting a target for test coverage (first action) might lead to people adding tests that don't genuinely test anything but merely inflate the metric (second-order consequence), potentially resulting in disillusionment with testing or continued incidents despite high coverage (third-order consequence). Conversely, giving someone ownership or autonom

This episode delves into the philosophical concept of hyperobjects – problems so vast and complex they lack clear boundaries and cannot be "solved" once and for all. It explores why attempting to permanently fix issues like technical debt, user experience, or performance management is often ineffective. Instead, it offers a new perspective: how to interact with and manage these intractable problems by focusing on specific outcomes and accepting their ongoing nature.Understand hyperobjects as problems that extend beyond clear boundaries and time, such as technical debt or performance management, which cannot be truly "solved".Discover why a "one-time fix" approach is an anti-pattern for hyperobjects, as their dynamic nature means solutions must also be continuous.Learn to shift your mindset from "solving" to "interacting" with these large, persistent problems, focusing on managing their effects rather than trying to contain them.Explore the importance of focusing on specific, achievable outcomes and taking "sn

This episode delves into a powerful model for encouraging behaviour change, applicable to both managing others and self-improvement, by focusing on three critical factors: Trigger, Incentive, and Ability. It challenges common, ineffective management approaches and provides insights into fostering new habits and desired actions by making the 'right' thing the 'easy' thing.Uncover why naive management approaches, such as mandating rules or blaming individuals, are ineffective at solving underlying behavioural problems or creating new, lasting habits.Learn about the Trigger, Incentive, and Ability model, a set of principles that can be applied to encourage specific actions in others or to facilitate self-betterment and incorporate new behaviours into your own life.Understand that Incentives are the critical factor in deciding what actions to pursue, driven by the question, "what's in it for me?". It's crucial for incentives to be clear and understood; an unclear incentive is effectively no incentive at all. Bene

This episode delves into the crucial role of well-positioned goals in a developer's career. It asserts that goals provide clarity, perspective, and purpose, particularly focusing on clarity as a primary benefit. The discussion challenges common struggles with goal setting, including the often-overlooked importance of relevance (the 'R' in SMART goals), suggesting that an irrelevant goal, no matter how specific or measurable, is ultimately ineffective. The core message highlights that the purpose of a goal is to serve as a clarifying and prioritising tool, enabling you to make decisions about what to do and focus your efforts, rather than simply doing work that is handed to you. You will learn to start small and focus on desired outcomes or what you want to be true, accepting that a goal only needs to be "directionally correct" rather than perfect. The episode also provides a practical heuristic: to set goals by considering how your boss will evaluate your performance in the future. It emphasises the importanc

Today we explore Cognitive Load Theory. This concept can profoundly influence how you structure your workday, manage teams, and approach learning in your career. The episode highlights that much of professional work, particularly in knowledge-based roles like software engineering, is fundamentally about learning. You will discover that there is an optimal amount of information processing for effective learning, and both overloading and underloading your cognitive capacity can be detrimental. A key insight is that cognitive load does not discriminate; all external factors, whether work-related or personal (e.g., tiredness, a messy desk), consume your finite cognitive capacity, leaving less "headroom" for optimal performance. Furthermore, cognitive load is not static but varies daily, impacted by an individual's diverse life experiences. The episode also delves into how skill development effectively lowers the cognitive load required for specific tasks, allowing individuals to achieve more with less mental effo

This episode focuses again on the fundamental principle that your systems are perfectly designed for the outcomes you are experiencing, regardless of whether those systems were intentionally or accidentally created.Here are the key takeaways from the episode:Uncover how your systems, whether intentionally or accidentally designed, are perfectly configured for the outcomes you experience. The implication of design means choices have been made in setting up a system, but your intent is less important than the actual outcomes produced.Learn why your intent is less important than the actual outcomes when evaluating your systems. If your intent was the sole factor, everyone would achieve their desired results. Instead, systems should be judged by the outcomes they generate.Discover the concept of "accidental design," where unseen factors influence system behaviour. This can be inspired by Goodhart's law, where a measure becomes a target and changes behaviour, or by environmental factors, such as how your workspace

This episode discusses why perfection is a dangerous and fragile goal, explaining how striving for 100% leads to unsustainable outlier states. It highlights how setting perfection as a bar can cause commitments to break and plans to fail due to a lack of slack, and offers strategies like building redundancy and planning with slack to achieve goals more effectively without relying on perfection.Uncover why perfection is a dangerous and fragile goal, as it often requires exorbitant, unsustainable effort and creates outlier states that are unlikely to be maintained, referencing the "Wedies effect" where things tend to regress to the mean.Learn how planning for 100% utilisation or setting perfection as a commitment can lead to fragility, causing plans to fail when unexpected changes occur or leading to giving up altogether once a "perfect" streak is broken.Discover practical strategies to avoid fragile perfectionism, such as planning with slack to accommodate change and building redundancy into your systems and p

This episode introduces the potentially controversial principle that your system is perfectly designed for its current outcomes, urging listeners to embrace greater responsibility for systemic issues. It explores how to redefine system boundaries to holistically integrate all influencing factors, like talent and organisational processes, ensuring that interventions are effective and targeted.Uncover the principle that your system is perfectly designed for the results you are getting, prompting a re-evaluation of what constitutes a "good" system when outcomes are undesirable.Learn why arbitrary system boundaries often lead to critical factors, such as talent, being excluded, and how to consider a system's full scope regardless of traditional lines of responsibility.Discover how incorporating talent and other seemingly external factors into your system design can lead to more efficient and effective solutions, rather than simply patching symptoms.Explore the distinction between judging decisions by their outcom

This episode explores the fundamental mindset of building your vocabulary, extending beyond literal words to conceptual understanding and mental models, and how Large Language Models (LLMs) can be a powerful tool for expanding and refining this crucial skill for career growth, clarity, and navigating disruptions.Uncover why building your vocabulary is a fundamental skill that can help you navigate career transitions, disruptions (such as those caused by AI), and changes in roles.Understand that "vocabulary" goes beyond literal words to include mental models, understanding your own self, specific diagrams (like causal loop diagrams or C4 diagrams), and programming paradigms or design patterns. This conceptual vocabulary provides access to nuanced and powerful ways of thinking.Learn how LLMs can be incredibly useful for refining and expanding your conceptual vocabulary, allowing you to explore new subjects, understand systems, and identify leverage points. They can help you understand the connotations, origins,

This episode delves into the use of substitute questions—simpler queries we use to answer more complex ones—and the crucial concept of cohesion between these substitutes and our true objectives. You'll learn how to leverage counterfactual thinking to scrutinize your assumptions and enhance the effectiveness of your decisions. Discover two powerful counterfactual techniques: asking "what else could be true?" to reveal alternative explanations, and employing thought experiments to, for example, precisely define your desires and career aspirations. The discussion offers practical applications, from refining hiring processes by identifying high-cohesion interview criteria to avoiding confirmation bias in debugging. By adopting counterfactual thinking, you can significantly improve your analytical skills, make more informed choices, and build robust strategies.Uncover how cognitively taxing questions lead us to use substitute questions as heuristics, and why understanding the cohesion between these is vital for ac

This episode explores why maintenance tasks, despite their fundamental importance, are often neglected or deprioritised in our daily lives and professional work. It delves into the psychological biases that make consistent maintenance challenging, such as hyperbolic discounting, where immediate gratification is valued over future gains, and the construal level theory, which highlights how psychological distance makes preventative work less impactful. The concept of the "maintenance paradox" is introduced, explaining that when maintenance is done well, its benefits go unnoticed, diminishing the sense of reward. The episode encourages listeners to adopt a maintenance mindset, making these tasks a standard habit rather than relying on typical prioritisation structures, as they are crucial for enhancing the quality of overall experiences and preventing future, more urgent problems.People tend to discount future gains or devalue them relative to immediate gratification, a concept known as hyperbolic discounting. T

This episode introduces a profound yet simple principle: knowing your baselines. This concept is crucial for effectively detecting and measuring change in your life and career.Uncover the fundamental idea that to recognise when something has changed, you must first understand what things were like before the change occurred. Often, people haven't been measuring their lives, making it challenging to spot shifts because their baselines are unknown.Learn to identify your personal baselines across various aspects of your life. This includes understanding typical daily habits, such as whether you tend to skip lunch, or how many hours you usually work (e.g., 6, 8, or 10 hours). While general data might suggest optimal working hours (e.g., 35-45 hours for most benefit, rarely more than 55 hours), your personal baseline is unique, and the goal is to empower you to make conscious decisions about your habits.Explore other crucial areas for baseline measurement, including simple health metrics like your typical body wei

This episode explores the complex landscape of receiving advice in your career, particularly during uncertain times. It offers insights on how to critically evaluate feedback and external information, prepare for potential negative outcomes outside of your control, and adapt your focus to thrive in a changing industry.Explore why the vast amount of advice you receive throughout your career, including feedback from bosses and peers, platitudes, anecdotes, data, opinions, and facts, will shape your thinking.Discover that even people you trust and consider authoritative may give advice you shouldn't listen to. Sometimes, all the positive signals and feedback you receive may not predict negative career events like layoffs or not getting a promotion.Learn not to stop listening to feedback, but instead listen for themes and common threads that resonate with your gut intuition.Understand the importance of contextualising people's assertions, testing them, and putting them through the wringer. However, even when foll

This episode addresses the fear surrounding industry changes, such as AI and potential outsourcing, and offers actionable advice for engineers, managers, and leaders to navigate these challenges. You'll learn why shifting your focus from just developing skills to embracing ownership and responsibility is crucial for long-term career resilience and agency.Understand the fear and concern that traditional skills may lose value due to industry changes, including AI and potential layoffs.Discover the critical shift needed in your career focus from solely developing skills towards embracing ownership and responsibility.Learn why responsibility and ownership are becoming increasingly valuable and are difficult to outsource or export, contrasting with skills which may become more fluid.Explore how human agency, including judging success, setting goals and direction, and translating inputs into action, complements or supervises work potentially done by machines or outsourced teams, with the human taking ultimate respo

This episode provides tactical ways to own your time, reduce meeting load and obligations, and regain agency, especially when feeling burnt out. You'll learn how to use a simple two-part model focusing on Pliability and Volatility to evaluate your tasks and meetings and make intentional choices about how you spend your time.Learn how owning your time is a critical first step in combating burnout, tiredness, and feeling worn out, helping you evaluate whether you feel agency over your time.Understand the principle that not all time is equal, whether it's sacred personal time or different times of day at work, and why you shouldn't treat it equally.Discover a simple two-part model using the characteristics of Pliability and Volatility to evaluate your obligations, such as meetings and tasks.Learn the definition of Pliability – how easily an obligation can be moved, changed, or cancelled, representing its flexibility.Understand the definition of Volatility – the risk, downsides, and potential compound negative ef

This episode explores the dichotomy between iterative planning and target state planning in software development, discussing the benefits and drawbacks of each approach and providing decision factors to help you choose the most appropriate method for your situation.Understand the core difference between iterative planning, which emphasises agility and responding to change with short planning horizons, and target state planning, which involves laying out a more defined long-term direction.Discover that while iterative planning is often considered the "right way" for software development, target state planning can be valuable for setting a general direction, which can be updated as you learn.Learn why addressing problems atomically in an iterative fashion can be valid, but that evaluating multiple potential improvements together with a target state in mind can lead to better coordination, efficiency, and consistency.Explore the decision factors that might lead you to favour iterative planning, such as high unce

This episode delves into practical principles for navigating the unexpected in your life and career. Rather than attempting to predict specific events, the focus is on cultivating resilience and optionality by identifying vulnerabilities in your systems and adopting a proactive mindset to transform potential challenges into strategic advantages.• Discover the three core principles of preparedness: first, build for change by investing in low-cost, high-upside options to prepare for many potential futures. Second, understand the weak points in your current systems (career, personal life, finances, etc.) to create mitigation strategies. Third, think like an engineer by identifying bottlenecks and single points of failure and pressure testing your life's resources.• Learn how to invest in optionality by pursuing low-cost, high-upside opportunities such as maintaining your professional network and reading books. These investments provide flexibility, improve negotiation power, and enhance your psychological positi

This episode introduces a simple yet highly effective communication habit that can be adopted by anyone to significantly reduce the risk of misunderstandings and enhance connection. It explores how this practice, which requires thoughtful communication but no special skills, can benefit individuals at all career levels.Discover why misunderstandings pose a significant risk to your career and how our natural inclination towards low-effort communication contributes to this risk.Learn the core of this high-leverage habit: restating what someone is telling you in your own words to ensure clarity and mutual understanding. This involves summarising or rephrasing the other person's message using your own terminology.Understand the multiple benefits of this technique, including demonstrating that you are actively listening, encoding the information more effectively for yourself, and most crucially, giving the other person the opportunity to correct your understanding.Explore how this habit provides a critical opportu

This episode introduces a valuable meta-tool for understanding the generic shapes of models, focusing specifically on the concept of logarithmic relationships and how they manifest as diminishing returns in various aspects of our lives and work. Understanding these patterns can help us make more informed decisions about where to invest our time and resources. Uncover a meta-tool for understanding generic model shapes, specifically focusing on the concept of logarithmic relationships, which operates at a layer above specific mental models. Learn about logarithmic complexity as a concept often encountered in algorithmic analysis and graphing math, characterised by a curve where the slope continuously decreases. Discover how diminishing returns serve as a colloquial way to understand logarithmic relationships, where each unit of input effort yields progressively smaller returns in value or output. Explore examples of where diminishing returns are evident, such as increasing the reliability of a system throug
