Douglas Crockford

(American computer programmer involved in the development of the JavaScript language.)


“We see a lot of feature-driven product design in which the cost of features is not properly accounted. Features can have a negative value to customers because they make the products more difficult to understand and use. We are finding that people like products that just work. It turns out that designs that just work are much harder to produce that designs that assemble long lists of features.”

“Math is important to programming; but it is only one of many important things. If you place too much emphasis on things that may be more important, like literacy, you are not putting enough emphasis on it.”

“Perfecting oneself is as much unlearning as it is learning.”

“The competent programmer is fully aware of the limited size of his own skull. He therefore approaches his task with full humility, and avoids clever tricks like the plague.”

“We shall do a much better programming job, provided that we approach the task with a full appreciation of its tremendous difficulty, provided that we stick to modest and elegant programming languages, provided that we respect the intrinsic limitations of the human mind and approach the task as Very Humble Programmers.”

“If we wish to count lines of code, we should not regard them as “lines produced” but as “lines spent.”

“Besides a mathematical inclination, an exceptionally good mastery of one’s native tongue is the most vital asset of a competent programmer.”

“I mean, if 10 years from now, when you are doing something quick and dirty, you suddenly visualize that I am looking over your shoulders and say to yourself “Dijkstra would not have liked this”, well, that would be enough immortality for me.”

“We have to fight chaos, and the most effective way of doing that is to prevent its emergence.”

“Simplicity and elegance are unpopular because they require hard work and discipline.”


Elisabeth Hendrickson

(Founder of Quality Tree Software, Inc.’in, tester and developer.)

Eric Evans

(A thought leader in software design and domain modeling and is the founder and author of Domain Language.

“Show me your flowcharts and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won’t usually need your flowcharts; they’ll be obvious.”

“You can learn more from failure than success. In failure you’re forced to find out what part did not work. But in success you can believe everything you did was great, when in fact some parts may not have worked at all. Failure forces you to face reality.”

Grady Booch

(An American software engineer, mostly known for developing Unified Modeling Language (UML). He has gained international recognition with his innovative work in software architecture, software engineering, and collaborative development environments)


“Good people with a good process will outperform good people with no process every time.”

(A world-renowned Certified Scrum Trainer with extensive experience working with start-ups, market leaders and public companies to increase their agility with Scrum and is the author of the book “Scrum Shortcuts Without Cutting Corners”)


“Scrum without automation is like driving a sports car on a dirt track – you won’t experience the full potential, you will get frustrated, and you will probably end up blaming the car.”



James Gosling

(A Canadian computer scientist, often referred to as “Dr. Java”, known as the founder and chief designer of the Java programming language. When Gosling realized that the electronic device embedded system project he started designing with C ++ was getting cumbersome, he started working on Java taking the best features of C ++ to create a user-friendly programming language; with less complex syntax.)


“Java is C++ without the guns, knives, and clubs.”


James Whittaker

(An American software tester, creator of the unFIX model, entrepreneur, and author of “How Google Tests Software”, “The 7 Stages of Creativity: Developing Your Creative Self”, “Exploratory Software Testing”)


“Small tests lead to code quality. Medium and large tests lead to product quality.”


Jef Raskin

(An American human-computer interface expert known for designing and launching the Macintosh project at Apple in the late 70s, the author of the book “The Humane Interface”)


“The place to start the implementation is to list exactly what the user will do to achieve his or her goals and how the system will respond to each user action.”

“If our field is ‘to advance’, we must – without displacing creativity and aesthetics – make sure our terminology is clear.”

“A well-designed and humane interface does not have to be split into beginner and expert subsystems.”

“An interface is humane if it is responsive to human needs and considerate of human frailties.”


Jeff Atwood

(An American software developer and writer, also co-founder of Stack Overflow and owner of the programming blog “Coding Horror”)


“The best reaction to “this is confusing, where are the docs” is to rewrite the feature to make it less confusing, not write more docs.”

“We have to stop optimizing for programmers and start optimizing for users.”


Jeff Bezos

(An American internet entrepreneur, industrialist, media proprietor, and investor, best known as the founder and CEO of Amazon)


“If your customer base is aging with you, then eventually you are going to become obsolete or irrelevant. You need to be constantly figuring out who are your new customers and what are you doing to stay forever young.”

“If you’re going to do anything new or innovative, you have to be willing to be misunderstood.”

“If you’re competitor-focused, you have to wait until there is a competitor doing something. Being customer-focused allows you to be more pioneering.”


Jeff Sutherland

(A software developer and one of the creators of the Scrum software development process, known as “Father of Scrum.” He contributed to the writing of the “Agile Manifesto” in 2001 and is the author of the “Scrum Guide.”)


“Scrum is like the rules of soccer. Following them does not make you a good player.”


Jeff Weiner

(The CEO of Linkedin)


“Almost without exception, the best products are developed by teams with desire to solve a problem; not a company’s need to fulfill a strategy.”


Jeremy Keith

(A web developer, musician and author.)


“Remember, the web isn’t about control. If a visitor to your site is familiar with using a browser’s native form doodad, you won’t be doing them any favors if you override the browser functionality with your own widget, even if you think your widget looks better.”


Jessica Gaston


“One man’s crappy software is another man’s full time job.”


Jessica Kerr

(A software developer, blogger and event speaker; currently works as DevOps and agile transformation consultant)


“A Fallacy of Software: If it works, and we don’t change anything, it will keep working.”


Jez Humble

(American code, infrastructure and product developer, author.)


“There are two rules of thumb architects follow when decomposing systems. First, ensure that adding a new feature tends to change only one service or a component at a time. This reduces interface churn.6 Second, avoid “chatty” or fine-grained communication between services. Chatty services scale poorly and are harder to impersonate for testing purposes.”


Jim Highsmith

(An American software engineer, author of many books on software development methodology, one of those who signed the “Agile Manifesto” and creator of the Adaptive Software Development concept)


“The best way to get a project done faster is to start sooner.”

“If we want to build great products, we need great people. If we want to attract and keep great people, we need great principles.”

“In high-performance teams, the leaders managed the principles, and the principles managed the team.”

“Agility is more attitude than process, more environment than methodology.”

“Simple rules guide innovative, intelligent responses. Comprehensive rules guide rote, routine responses.”

“The quality of results from any collaboration effort are driven by trust and respect.”

“Agile development reflects a product lifecycle approach, rather than a project approach.”


Jim McCarthy

(An author, keynote speaker, co-creator of Core Protocols with Michele McCarthy, author of “Software for Your Head” and “Dynamics of Software Development” and has a patent on instant messaging. Worked at Bell Laboratories, Whitewater Group, and Microsoft)


“You can’t have great software without a great team, and most software teams behave like dysfunctional families.”


Joel Goldberg

(An American software developer.)


“Teams move at the speed of trust. Be the kind of dependable person you would want to work with.”


Joel Spolsky

(An American software engineer and author)


“We’re programmers. Programmers are, in their hearts, architects, and the first thing they want to do when they get to a site is to bulldoze the place flat and build something grand. We’re not excited by incremental renovation: tinkering, improving, planting flower beds.”


John Backus

(An American computer scientist, led the team that created the FORTRAN, the inventor of the Backus-Naur form (BNF), developed the functional programming language “FP”, which advocated a mathematical approach to programming. In 1994, he received the Draper Award.)


“I myself have had many failures and I’ve learned that if you are not failing a lot, you are probably not being as creative as you could be, you aren’t stretching your imagination enough.”


John Carmack

(A computer programmer, video game developer, and engineer; led the team developing games such as Commander Keen, Wolfenstein 3D, Doom, and Quake)


“Programming is not a zero-sum game. Teaching something to a fellow programmer doesn’t take it away from you.”

“The cost of adding a feature isn’t just the time it takes to code it. The cost also includes the addition of an obstacle to future expansion. The trick is to pick the features that don’t fight each other.”

“Focus is a matter of deciding what things you’re not going to do.”

“Focused, hard work is the real key to success. Keep your eyes on the goal, and just keep taking the next step towards completing it. If you aren’t sure which way to do something, do it both ways and see which works better.”


John Cutler

(Started his career as a game developer, specialized in product management, accepted as an opinion leader in product management, his articles published in many different sources, known with the article “50 Things I’ve Learned About Product Management”)


“You tend to go where you look. If you look too hard at the competition you’ll go towards them, instead of towards point ahead of them.”

“If in doubt, get out of your head and gather data. Build something and test. Same goes with meetings where there is endless conjecture. Have a bias for action!”

“All bets are off until someone is trying to use the feature with their data, in their environment, in their day to day work. You have to leave time to iterate based on that feedback.”

“Trying to land a 747 on a speedboat is never a good idea. Work in small batches, and plan at the last responsible moment.”

“Driving out all uncertainty tends to drive out originality (and innovation).”

“Passing the trash to other departments (e.g. “support will deal with it”) always comes back to bite you.”

“Without a strong product vision, you’ll end up outsourcing product strategy to the rest of the company.”


John Johnson

“First solve the problem then write the code.”


John Maeda

(An American executive, designer and technologist.)


“Simplicity is about the unexpected pleasure derived from what is likely to be insignificant and would otherwise go unnoticed.”


John Ousterhout

(An American computer science professor and author.)


“Your job as a developer is not just to create code that you can work with easily, but to create code that others can also work with easily.”

“You’ll end up with a much better result if you consider multiple options for each major design decision.“


John Romero

(An American director, designer, programmer and developer working in the gaming industry; co-founder of the company that created games such as Wolfenstein 3D, Dangerous Dave, Hexen, Doom, Doom II, and Quake, and the designer of the games)


“You might not think that programmers are artists, but programming is an extremely creative profession. It’s logic-based creativity.”


John Warnock

(An American computer scientist and business person, invented the PostScript language, best known as the co-founder of Adobe Systems Inc., pioneered the development of graphics, publishing, web and electronic document technologies that have revolutionized the field of publishing and visual communications)


“It’s very important that a programmer be able to look at a piece of code like a bad chapter of a book and scrap it without looking back. Never get too enamored with one idea, never hang onto anything tenaciously without being able to throw it away when necessary; that should be the programmer’s attitude.”

“Learn from small experiments rather than large ones. Don’t go into a two-year development with nothing coming out in the middle. Have something come out every two months, so you can evaluate, regroup, and restart.”

“To be successful, you want to surround yourself with very talented folks whose skills blend very well. That’s the secret of success.”


John F. Woods

(A game programmer, no information was found other than the email he sent to the comp.lang.c ++ newsgroup in September 1991.)


“Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live.”


Joshua Bloch

(An American software engineer, published many books on Java including “Effective Java”, led the design and implementation of numerous Java platform features, including the Java Collections Framework, the java.math package, and the assert mechanism.)


“When you choose a language, you’re choosing more than a set of technical trade-offs-you’re choosing a community.”



Kathryn Barrett

(Self-taught coder since the age of 12, now teaches coding to children in Canada at Learning Labs – the institution that promotes organizations such as Learning Learning Code, Girls Learning Code, Kids Learning Code, and HackerYou.)


“Falling in love with code means falling in love with problem solving and being a part of a forever ongoing conversation. To be a computer programmer does not mean to live in isolation and solitude, but rather the exact opposite.”


Karolina Szczur

(A designer and front-end developer, wrote the article “On writing maintainable front-end systems” in 2015.)


“Writing software as if we are the only person that ever has to comprehend it is one of the biggest mistakes and false assumptions that can be made.”


Kelsey Hightower

(A strong open source advocate, has worn every hat possible from technical support to software development or system administration, and has held various leadership roles throughout his career in technology, currently works as a “Staff Developer Advocate” at Google Cloud)


“Maintaining an open-source project is like being a flight attendant for an airline where all tickets are free and the majority of customer surveys offer suggestions on how to fly the airplane.”


Kent Beck

(An American software engineer, creator of the agile software development methodology “Extreme Programming”, one of the 17 original signatories of “Agile Manifesto” and a pioneer of the software design patterns)


“I’m not a great programmer; I’m just a good programmer with great habits.”

“The craft of programming begins with empathy, not formatting or languages or tools or algorithms or data structures.”

“Optimism is an occupational hazard of programming; feedback is the treatment.”

“Tests are the Programmer’s stone, transmuting fear into boredom.”

“Everything in software changes. The requirements change. The design changes. The business changes. The technology changes. The team changes. The team members change. The problem isn’t change, because change is going to happen; the problem, rather, is our inability to cope with change.”

“Readers need to understand programs in detail and in concept. Sometimes they move from detail to concept, sometimes from concept to detail.”



Larry Bernstein

(A software engineering professor, teaching software architecture at NJCSE, led major software projects at Bell Labs for 35 years)


“Don’t automate an undisciplined workflow. The computer won’t solve what the customer’s management can’t.”


Larry Bossidy

(An American writer and retired businessman served as CEO of AlliedSignal -later Honeywell in the 1990s. He previously served in executive positions at General Electric for over 30 years.)


“Complexity has nothing to do with intelligence, simplicity does.”

“The foundation of changing behavior is linking rewards to performance and making the linkages transparent.”

“The hardware of a computer is useless without the right software. Similarly, in an organization the hardware (strategy and structure) is inert without the software (beliefs and behaviors).”


Larry Constantine

(A software engineer and professor at the Department of Mathematics and Engineering at Madeira University, has many publications on software science and corporate culture, considered as one of the pioneers of structural software design methodologies and specializes in interaction design and usability in complex systems)


“The best meetings get real work done. When your people learn that your meetings actually accomplish something, they will stop making excuses to be elsewhere.”


Larry Flon

(An American computer science professor)


“There is no programming language, no matter how structured, that will prevent programmers from making bad programs.”


Larry Wall

(The creator of the Perl programming language)


“The three chief virtues of a programmer are: Laziness, Impatience and Hubris.

Laziness: The quality that makes you go to great effort to reduce overall energy expenditure. It makes you write labor-saving programs that other people will find useful and document what you wrote so you don’t have to answer so many questions about it.

Impatience: The anger you feel when the computer is being lazy. This makes you write programs that don’t just react to your needs, but actually anticipate them. Or at least pretend to.

“Hubris: The quality that makes you write (and maintain) programs that other people won’t want to say bad things about.”

“Computer languages differ not so much in what they make possible, but in what they make easy.”


Larry Tesler

(A computer scientist who worked at Apple between 1980 and 1997, recognized as the inventor of the “Cut-Copy-Paste” commands on computers.)


“Every application has an inherent amount of irreducible complexity. The only question is who will have to deal with it, the user or the developer (programmer or engineer).”


Laurence J. Peter

(A Canadian educator and writer, best known for his “Peter principle” on hierarchy, published “Peter’s Almanac” in 1982)


“Some problems are so complex that you have to be highly intelligent and well informed just to be undecided about them.”


Linus Torvalds

(A software engineer and the creator of the Linux kernel)


“Most good programmers do programming not because they expect to get paid or get adulation by the public, but because it is fun to program.”

“Theory and practice sometimes clash. And when that happens, theory loses. Every single time.”

“Telling people “don’t do that” simply doesn’t work. Not if they can do it easily anyway. Things really don’t get fixed unless people have a certain pain-level to induce it to get fixed.”


Lisa Crispin

(Specialized in agile methodologies and testing, has four books, helps testing community learn about DevOps and continuous delivery, and helps agile and DevOps communities know about testing, explores best practices in testing in the software community.)


“People, not methodologies or tools, make projects successful.”


Louis Srygley

(Has 30+ years of software career, is also a producer and an actor)


“Without requirements or design, programming is the art of adding bugs to an empty text file.”



Marc Donner

(An American computer scientist with a Ph.D. in robotics, worked at companies such as IBM Watson Research Center, Google, and Uber)


“Of all my programming bugs, 80% are syntax errors. Of the remaining 20%, 80% are trivial logical errors. Of the remaining 4%, 80% are pointer errors. And the remaining 0.8% are hard.”


Mario Fusco

(An Italian software engineer and Java expert, the author of the book “Java 8 in Action: Lambdas, Streams, and Functional-style Programming”, co-author of the book “Modern Java in Action”, currently works as “Drools Core Developer” in Red Hat)


“The code you write makes you a programmer. The code you delete makes you a good one. The code you don’t have to write makes you a great one.”

“Sometimes a bug is so big & you’re so focused on details that discovering it is like finding an elephant with a microscope. Take a step back.”

“Programs, like people, get old. We can’t prevent ageing, but we can understand its causes, limit its effects and reverse some of the damage.”

“You can optimise for low latency. You can optimise for high throughput. You can optimise for memory occupation. However 90% of times the most precious thing you should optimise for is maintainability.”


Mark Berry

(A software engineer and entrepreneur)


“Programmers don’t burn out on hard work, they burn out on change-with-the-wind directives and not ‘shipping’”


Mark Fewster

(A consultant in the field of test techniques and test automation, lecturer, author, speaker, co-author of the book “Software Test Automation”, has more than 20 years of industry experience in the field of software testing)


“It is far better to improve the effectiveness of testing first than to improve the efficiency of poor testing. Automating chaos just gives faster chaos.”


Martin Fowler

(An English software developer specialized in agile software development methodologies including object-oriented analysis and design, UML, patterns and over-programming, a writer and an international speaker on software development, the author of many books including “Refactoring”)


“If you’re afraid to change something it is clearly poorly designed.”

“Whenever I have to think to understand what the code is doing, I ask myself if I can refactor the code to make that understanding more immediately apparent.”

“A heuristic we follow is that whenever we feel the need to comment something, we write a method instead.”

“If you can get today’s work done today, but you do it in such a way that you can’t possibly get tomorrow’s work done tomorrow, then you lose.”

“I’m opposed to setting aside time for refactoring. In my view refactoring is not an activity you set aside time to do. Refactoring is something you do all the time in little bursts.”

“When you find you have to add a feature to a program, and the program’s code is not structured in a convenient way to add the feature, first refactor the program to make it easy to add the feature, then add the feature.”


Mary Poppendieck

(Started her career as a process control programmer, led the IT department of a manufacturing facility, and then shifted to product development, wrote four books on “Lean Software Development”, including “Implementing Lean Software Development: From Concept to Cash”)


“Every line of code costs money to write and more money to support. It is better for the developers to be surfing than writing code that won’t be needed.”

“The biggest cause of failure in software-intensive systems is not technical failure; it’s building the wrong thing.”

“Almost everything we know about good software architecture has to do with making software easy to change.”

“It is much more important to develop people with the expertise to make wise decisions than it is to develop decision-making processes that purportedly think for people.”

“It would be much better to assign work to established teams than to reconstitute teams around projects.”

“A disciplined approach to problem solving moves a team from wishful thinking to new knowledge, specific countermeasures, and permanent results.”

“The job of tests, and the people that develop and runs tests, is to prevent defects, not to find them.”

“If the vision of perceived integrity isn’t refreshed regularly, the engineers have a tendency to get lost in the technical details and forget the customer values.”


Max Kanat-Alexander

(Software developer at Google and author of ‘Code Simplicity’)


“Some of the best programming is done on paper, really. Putting it into the computer is just a minor detail.”

“Simplifying your code decreases the effort of maintenance, thereby increasing the desirability of every other possible change.”


Melinda Varian

(A programmer and an academician at Princeton University has studies and articles on the history of IBM’s virtual machine operating system VM)


“The best programs are the ones written when the programmer is supposed to be working on something else.”


Mich Ravera

(A software developer and publisher)


“If it doesn’t work, it doesn’t matter how fast it doesn’t work.”


Michael Feathers

(Specialized in software and organizational design, has provided consultancy support to hundreds of organizations in the past 20 years on general software design, process change and code animation, is the author of “Working Effectively With Legacy Code”)


“Remember, code is your house, and you have to live in it.”

“The brutal truth is that architecture is too important to be left exclusively to a few people. It’s fine to have an architect, but the key way to keep an architecture intact is to make sure that everyone on the team knows what it is and has a stake in it.”

“Code without tests is bad code. It doesn’t matter how well written it is; it doesn’t matter how pretty or object-oriented or well-encapsulated it is. With tests, we can change the behavior of our code quickly and verifiably. Without them, we really don’t know if our code is getting better or worse.”

“Clean code always looks like it was written by someone who cares.”

“In a well-maintained system, it might take a while to figure out how to make a change, but once you do, the change is usually easy and you feel much more comfortable with the system. In a legacy system, it can take a long time to figure out what to do, and the change is difficult also.”


Michael Hartung

(A computer hardware specialist who has worked at IBM for many years, was appointed an IBM Fellow in 2002)


“Hardware eventually fails. Software eventually works.”


Michael A. Jackson

(A British computer scientist and computing consultant, visiting research professor at Open University in the UK, and author of many books)


“We follow two rules in the matter of optimization:

Rule 1: Don’t.

Rule 2: (for experts only). Don’t do it yet – that is, not until you have a perfectly clear and unoptimized solution.”


Michael Lopp

(An American software engineering executive, blogger, known as “Rands”, and the author of “The Art of Leadership: Small Things, Done Well”, “Managing Humans: Biting and Humorous Tales of a Software Engineering Manager” and “Being Geek: The Software Developer’s Career Handbook”.)


“A software metaphor is more like a searchlight than a road map. It doesn’t tell you where to find the answer; it tells you how to look for it.“


Michael Nygard

(An American programmer, architect and author.)


“Design with skepticism, and you will achieve resilience. Ask, “What can system X do to hurt me?” and then design a way to dodge, duck, dip, dive, and dodge whatever wrench your supposed ally throws.”


Mike Cohn

(Contributed to the development of Scrum, one of the founders of the Scrum Alliance, has books on agile methodology, supports the daily stand-up meetings)


“The benefit of allowing a team to self-organize isn’t that the team finds some optimal organization for its work that a manager may have missed. Rather, it is that by allowing the team to self-organize, it is encouraged to fully own the problem of performing its work.”

“Because the estimate for each feature is made relative to the estimates for other features, it does not matter if our estimates are correct, a little incorrect, or a lot incorrect. What matters is that they are consistent.”

“Individuals should be given every incentive possible to work as a team. If the team’s throughput is increased by my helping someone else, that’s what I should do.”


Mike Krieger

(Brazilian-Amerikan entrepreneur, software engineer and Instagram co-founder.)


“You can’t start a product simply by building it. You have to know why you’re building it, and you might go down the wrong rabbit hole, waste time, and confuse things. Spending long afternoons with a sketchbook or talking through your ideas with other people can save a year in software development later on.”


Mikko Hypponen

(Finnish computer security and privacy expert and columnist, known globally for the Hypponen Law on IoT security)


“Rarely is anyone thanked for the work they did to prevent the disaster that didn’t happen.”

Neal Ford

(Completed his university education as a computer scientist who specializes in languages and compilers and a mathematician who specializes in statistical analysis. Known as an expert in agile engineering techniques and software architecture. Has many articles, books, and videos on software architecture, continuous distribution, functional programming)


“The problem with a completely new programming paradigm isn’t learning a new language. After all, everyone reading this has learned numerous computer languages—language syntax is merely details. The tricky part is learning to think in a different way.”


Nicole Forsgren

(An American technology executive, entrepreneur, and author.)


“Architects should collaborate closely with their users—the engineers who build and operate the systems through which the organization achieves its mission—to help them achieve better outcomes and provide them the tools and technologies that will enable these outcomes.”


“Responsibilities of a team leader include limiting work in process and eliminating roadblocks for the team so they can get their work done.”


Nicoll Hunt

(Has 20+ years in the software, mainly worked in game development and developed games such as Fist Of Awesome, Shirtless Bear-Fighter, Maximum Car, 8-Bit Waterslide)


“The first step of any project is to grossly underestimate its complexity and difficulty.”


Niklaus Wirth

(A Swiss computer scientist, designed many programming languages including Pascal, and pioneered classical topics in software engineering)


“A primary cause of complexity is that software vendors uncritically. adopt almost any feature that users want.”

Norman Ralph Augustine

(A businessman who worked in the field of aviation and space and chaired the “Human Space Flight Plans Committee” and published the “Augustine’s Laws” list in 1984)


“Software is like entropy. It is difficult to grasp, weighs nothing, and obeys the second law of thermodynamics; i.e. it always increases.”



Oscar Godson

(A software developer and entrepreneur)


“One of the best programming skills you can have is knowing when to walk away for a while.”



Pamela Zave

(An American computer scientist, known for his work on software requirements engineering, telecommunications services, protocol modeling, and validation. Currently working on network architecture at Princeton University)


“The purpose of software engineering is to control complexity, not to create it.”


Patrick Collison

(Irish entrepreneur and co-founder of Stripe.)


“Programming is full of odd ideas. Using shorter, less descriptive names often produces code that’s more readable overall. The most powerful languages usually have far fewer concepts than the lesser ones. And failing may be the best way to produce successful and original work.”


Patrick McKenzie

(A software engineer and entrepreneur, has many articles on programming and software marketing)


“Every great developer you know got there by solving problems they were unqualified to solve until they actually did it.”


Paul Butcher

(Started his career writing games for 8-bit home computers before he was a teenager, and since then has worked in diverse fields at all levels of abstraction, from microcode on bit-slice processors to high-level declarative programming, is the author of “Debug It!”)


“Bug fixing often uncovers opportunities for refactoring. The very fact that you’re working with code that contains a bug indicates that there is a chance that it could be clearer or better structured.”


Paul Graham

(He is an American computer scientist, entrepreneur and author.)


“When you catch bugs early, you also get fewer compound bugs.  Compound bugs are two separate bugs that interact:  you trip going downstairs, and when you reach for the handrail it comes off in your hand.”

“A programming language is for thinking about programs, not for expressing programs you’ve already thought of. It should be a pencil, not a pen.”

“If you look inside good software, you find that parts no one is ever supposed to see are beautiful too. I’m not claiming I write great software, but I know that when it comes to code I behave in a way that would make me eligible for prescription drugs if I approached everyday life the same way. It drives me crazy to see code that’s badly indented, or that uses ugly variable names.”

“As for building something users love, here are some general tips. Start by making something clean and simple that you would want to use yourself.”

“You have to be able to see things from the user’s point of view.”

“Design and research are aiming for the same destination, just approaching it from different directions.”


Pearl Zhu

(A software developer and author.)


“One of the reasons to see improved productivity in Agile is because of the simplicity principle.”


Peter Roizen

(A Canadian software developer, game creator and entrepreneur.)


“I’ve seen many intelligent people who are just not practical. They get lost pursuing some academic goal that is totally useless. Being practical is important to good programming. You must be able to guess accurately how long it will take to complete a project, have the ability to calculate what can and cannot be done in that time, and then do it, resisting the temptation to go off and do other things. Practicality is important when you’re trying to make every piece of work the best because you always have a limited amount of time to work on it. It’s easy to triple the time to complete a project when you’re consumed with making it the ultimate in elegance.”



Radia Perlman

(An American computer programmer and network engineer, mostly known for her invention of the spanning-tree protocol (STP) and known as the “mother of the internet”, has made extensive contributions to many other areas of network design and standardization)


“The world would be a better place if more engineers, like me, hated technology. The stuff I design, if I’m successful, nobody will ever notice. Things will just work, and will be self-managing.”


Ralph Johnson

(A computer science researcher, one of the authors of the book “Design Patterns: Elements of Reusable Object-Oriented Software”)


“Before software can be reusable, it first has to be usable.”


Rasmus Lerdorf

(The creator of PHP programming language)


“PHP is about as exciting as your toothbrush. You use it every day, it does the job, it is a simple tool, so what? Who would want to read about toothbrushes?”


Ray Ozzie

(Former Microsoft CTO, a software architect, and entrepreneur)


“Complexity kills. It sucks the life out of developers, it makes products difficult to plan, build and test, it introduces security challenges, and it causes end-user and administrator frustration.”

“Bugs are often characteristic of a bad interface between subsystems, which is frequently a result of inadequate communication among people when they design the subsystems. When a bug is found, there is a tendency to handle it within the subsystem and not look at the program as a whole.”


Rebecca Parsons

(American computer science professor and Chief Technology Officer of ThoughtWorks.)


“It’s never too early to think about performance.”


Richard Dalton

(An experienced Irish software developer, trainer, and mentor)


“Teams are immutable. Every time someone leaves, or joins, you have a new team, not a changed team.”


Richard Kenneth Eng

(A Canadian software developer with 30+ years of software and programming experience in a wide range of languages and fields)


“Simple, elegant languages remove the cognitive burden that afflicts users of more complex languages, so the theory goes. Programmers can be more productive and not waste time overcoming a substantive learning curve.”


Richard Monson-Haefel

(A senior software engineer, independent consultant, publishes books for O’Reilly and Pluralsight)


“You don‘t drive the architecture, the requirements do.”

“Design is a discovery process, as we implement we discover new information, often impossible to know up front.”


Richard E. Pattis

(A professor of computer science, the creator of Karel programming language, currently teaching introductory programming and data structures at the University of California)


“When debugging, novices insert corrective code; experts remove defective code.”

“Code should run as fast as necessary, but no faster; something important is always traded away to increase speed.”

“If you cannot grok the overall structure of a program while taking a shower, you are not ready to code it.”

“The structure of a software system provides the ecology in which code is born, matures, and dies. A well-designed habitat allows for the successful evolution of all the components needed in a software system.”


Richard Stallman

(An American free software activist and programmer.)


“Creativity can be a social contribution, but only in so far as society is free to use the results.”


Rick Lemons

(A software consultant working on software analysis, architecture, application, and management for 20+ years)


“Don’t make the user provide information that the system already knows.”


Rob Pike

(A Canadian programmer and author.)


“Data dominates. If you’ve chosen the right data structures and organized things well, the algorithms will almost always be self-evident. Data structures, not algorithms, are central to programming.”


Robert C. Martin

“The big optimizations come from refining the high-level design, not the individual routines.”

“Once you start coding, you get emotionally involved with your code and it becomes harder to throw away a bad design and start over.”

“A good estimate is an estimate that provides a clear enough view of the project reality to allow the project leadership to make good decisions about how to control the project to hit its targets.”

“The default movement on a software project should be in the direction of taking elements of the software away to make it simpler rather than adding elements to make it more complex.”

“Motivation is undoubtedly the single greatest influence on how well people perform.”

Vaughn Vernon

(A veteran software craftsman and thought leader in simplifying software design and implementation. )


“Developers are too wrapped up with technology and trying to solve problems using technology rather than careful thought and design. This leads developers to constantly chase after new “shiny objects,” which are the latest fads in technology.”

“The best way to get the right answer on the Internet is not to ask a question, it’s to post the wrong answer.”

“It was a turning point in my programming career when I realized that I didn’t have to win every argument. I’d be talking about code with someone, and I’d say, “I think the best way to do it is A.” And they’d say, “I think the best way to do it is B. I’d say, “Well no, it’s really A.” And they’d say, “Well, we want to do B.” It was a turning point for me when I could say, “Fine. Do B. It’s not going to hurt us that much if I’m wrong. It’s not going to hurt us that much if I’m right and you do B, because, we can correct mistakes. So lets find out if it’s a mistake.”

“Putting a new feature into a program is important, but refactoring so new features can be added in the future is equally important.”

“Over and over, people try to design systems that make tomorrow’s work easy. But when tomorrow comes it turns out they didn’t quite understand tomorrow’s work, and they actually made it harder.”
