This article provides an overview of various laws and principles in software engineering that guide team organization, architecture design, quality assurance, planning, and decision-making processes. It covers topics such as Conway's Law, Premature Optimization, Hyrum's Law, The Boy Scout Rule, YAGNI (You Aren't Gonna Need It), Brooks's Law, and others.
These principles guide the development process, ensuring that software is designed efficiently, effectively, and sustainably, potentially leading to better user experiences and more reliable systems in various industries.
- Conway's Law: Organizations design systems that mirror their own communication structure.
- Premature Optimization (Knuth's Optimization Principle): Premature optimization is the root of all evil.
- Hyrum's Law: With a sufficient number of API users, all observable behaviors of your system will be depended on by somebody.
- The Boy Scout Rule: Leave the code better than you found it.
- YAGNI (You Aren't Gonna Need It): Don't add functionality until it is necessary.
- Brooks's Law: Adding manpower to a late software project makes it later.
- Gall's Law: A complex system that works is invariably found to have evolved from a simple system that worked.
- The Law of Leaky Abstractions: All non-trivial abstractions, to some degree, are leaky.
- Tesler's Law (Conservation of Complexity): Every application has an inherent amount of irreducible complexity that can only be shifted, not eliminated.
- CAP Theorem: A distributed system can guarantee only two of: consistency, availability, and partition tolerance.
- Second-System Effect: Small, successful systems tend to be followed by overengineered, bloated replacements.
- Fallacies of Distributed Computing: Eight false assumptions that new distributed system designers often make.
- Law of Unintended Consequences: Whenever you change a complex system, expect surprise.
- Zawinski's Law: Every program attempts to expand until it can read mail.
- Dunbar's Number: There is a cognitive limit of about 150 stable relationships one person can maintain.
- The Ringelmann Effect: Individual productivity decreases as group size increases.
- Price's Law: The square root of the total number of participants does 50% of the work.
- Putt's Law: Those who understand technology don't manage it, and those who manage it don't understand it.
- Peter Principle: In a hierarchy, every employee tends to rise to their level of incompetence.
- Bus Factor: The minimum number of team members whose loss would put the project in serious trouble.
- Dilbert Principle: Companies tend to promote incompetent employees to management to limit the damage they can do.
- Parkinson's Law: Work expands to fill the time available for its completion.
- The Ninety-Ninety Rule: The first 90% of the code accounts for the first 90% of development time; the remaining 10% accounts for the other 90%
- Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law.
- Goodhart's Law: When a measure becomes a target, it ceases to be a good measure.
- Gilb's Law: Anything you need to quantify can be measured in some way better than not measuring it.
- Murphy's Law / Sod's Law: Anything that can go wrong will go wrong.
- Postel's Law: Be conservative in what you do, be liberal in what you accept from others.
- Broken Windows Theory: Don't leave broken windows (bad designs, wrong decisions, or poor code) unrepaired.
- Technical Debt: Technical Debt is everything that slows us down when developing software.
- Linus's Law: Given enough eyeballs, all bugs are shallow.
- Kernighan's Law: Debugging is twice as hard as writing the code in the first place.
- Testing Pyramid: A project should have many fast unit tests, fewer integration tests, and only a small number of UI tests.
- Pesticide Paradox: Repeatedly running the same tests becomes less effective over time.
- Lehman's Laws of Software Evolution: Software that reflects the real world must evolve, and that evolution has predictable limits.
- Sturgeon's Law: 90% of everything is crap.
- Amdahl's Law: The speedup from parallelization is limited by the fraction of work that cannot be parallelized.
- Gustafson's Law: It is possible to achieve significant speedup in parallel processing by increasing the problem size.
- Metcalfe's Law: The value of a network is proportional to the square of the number of users.
- DRY (Don't Repeat Yourself): Every piece of knowledge must have a single, unambiguous, authoritative representation.
- KISS (Keep It Simple, Stupid): Designs and systems should be as simple as possible.
- SOLID Principles: Five main guidelines that enhance software design, making code more maintainable and scalable.
- Law of Demeter: An object should only interact with its immediate friends, not strangers.
- Principle of Least Astonishment: Software and interfaces should behave in a way that least surprises users and other developers.
- Dunning-Kruger Effect: The less you know about something, the more confident you tend to be.
- Hanlon's Razor: Never attribute to malice that which is adequately explained by stupidity or carelessness.
- Occam's Razor: The simplest explanation is often the most accurate one.
- Sunk Cost Fallacy: Sticking with a choice because you've invested time or energy in it, even when walking away helps you.
- The Map Is Not the Territory: Our representations of reality are not the same as reality itself.
- Confirmation Bias: A tendency to favor information that supports our existing beliefs or ideas.
- The Hype Cycle & Amara's Law: We tend to overestimate the effect of a technology in the short run and underestimate the impact in the long run.
- The Lindy Effect: The longer something has been in use, the more likely it is to continue being used.
- First Principles Thinking: Breaking a complex problem into its most basic blocks and then building up from there.
- Inversion: Solving a problem by considering the opposite outcome and working backward from it.

A new study in Science reveals that warming oceans pose a significant risk to mesothermic marine species, including great white sharks and tuna. These species require more energy to maintain their body temperature than cold-blooded counterparts, leading to potential fatal overheating as water temperatures rise.
Mesothermic marine species, including great white sharks and tuna, may face population declines due to overheating and food scarcity, potentially disrupting ocean ecosystems.
- As oceans warm, these species face a 'double jeopardy' of declining food sources due to overfishing and warming waters.
- Species must slow down, alter blood flow or dive to cooler temperatures while hunting for dwindling food supply.
Discussion (42):
The comment thread discusses a scientific paper on the energetics of large aquatic animals, particularly their sensitivity to warming waters. It also includes a debate about the potential impact of global veganism on carbon emissions.
- The paper's findings suggest a scaling imbalance between heat production and loss for large aquatic animals in warm waters.
Counterarguments:
- Transitioning the entire planet to veganism would lead to significant food supply issues and might not result in a 60% reduction in carbon emissions.
