Give me six hours to chop down a tree and I will spend the first four sharpening the axe. (Abraham Lincoln)
A collection of full-stack resources for programmers.
The goal of this page is to make you a more proficient developer. You’ll find only resources that I’ve found truly inspiring, or that have become timeless classics.
This page is not meant to be comprehensive. I am trying to keep it light and not too overwhelming. The selection of articles is opinionated.
- 🧰 : list of resources
- 📖 : book
- 🎞 : video/movie extract/movie/talk
- 🏙 : slides/presentation
- ⭐️ : must-read
Feel free to open a PR to contribute! I will not be adding everything: as stated above, I am trying to keep the list concise.
I’ve found these books incredibly inspiring:
- 📖 The Pragmatic Programmer: From Journeyman to Master: hands-on the most inspiring and useful book I’ve read about programming.
- 📖 Code Complete: A Practical Handbook of Software Construction: a nice addition to The Pragmatic Programmer, gives you the necessary framework to talk about code.
- 📖 Release It!: this books goes beyond code and gives you best practices for building production-ready software. It will give you about 3 years worth of real-world experience.
- 📖 Scalability Rules: 50 Principles for Scaling Web Sites
- 📖 The Linux Programming Interface: A Linux and UNIX System Programming Handbook: outside of teaching you almost everything you need to know about Linux, this book will give you insights into how software evolves, and the value of having simple & elegant interfaces.
- 📖 Structure and interpretation of Computer Programs (free): One of the most influential textbooks in Computer Science (written and used at MIT), SICP has been influential in CS education. Byte recommended SICP “for professional programmers who are really interested in their profession”.
There are some free books available, including:
- 📖 Professional software development: pretty complete and a good companion to this page. The free chapters are mostly focused on software development processes: design, testing, code writing, etc. - and not so much about tech itself.
- 🧰 vhf/free-programming-books
- 🧰 EbookFoundation/free-programming-books
- Practical Advice for New Software Engineers
- On Being A Senior Engineer
- Lessons Learned in Software Development: one of those articles that give you years of hard-earned lessons, all in one short article. Must read.
- Things I Learnt The Hard Way
- Spec first, then code
- Tests make better APIs
- Future thinking is future trashing
- Documentation is a love letter to your future self
- Sometimes, it’s better to let the application crash than do nothing
- Understand and stay away of cargo cult
- “Right tool for the job” is just to push an agenda
- Learn the basics functional programming
- ALWAYS use timezones with your dates
- ALWAYS use UTF-8
- Create libraries
- Learn to monitor
- Explicit is better than implicit
- Companies look for specialists but keep generalists longer
- The best secure way to deal with user data is not to capture it
- When it’s time to stop, it’s time to stop
- You’re responsible for the use of your code
- Don’t tell “It’s done” when it’s not
- Pay attention on how people react to you
- Beware of micro-aggressions

- Signs that you’re a good programmer
- Signs that you’re a bad programmer
- 7 absolute truths I unlearned as junior developer
- Early in your career, you can learn 10x more in a supportive team in 1 year, than coding on your own
- Every company has problems, every company has technical debt.
- Being overly opinionated on topics you lack real-world experience with is pretty arrogant.
- Many conference talks cover proof of concepts rather than real-world scenarios.
- Dealing with legacy is completely normal.
- Architecture is more important than nitpicking.
- Focus on automation over documentation where appropriate.
- Having some technical debt is healthy.
- Senior engineers must develop many skills besides programming.
- We’re all still junior in some areas.
- How to Build Good Software
- A good high-level summary of fundamental engineering practices.
- The root cause of bad software has less to do with specific engineering choices, and more to do with how development projects are managed.
- There is no such thing as platonically good engineering: it depends on your needs and the practical problems you encounter.
- Software should be treated not as a static product, but as a living manifestation of the development team’s collective understanding.
- Software projects rarely fail because they are too small; they fail because they get too big.
- Beware of bureaucratic goals masquerading as problem statements. If our end goal is to make citizens’ lives better, we need to explicitly acknowledge the things that are making their lives worse.
- Building software is not about avoiding failure; it is about strategically failing as fast as possible to get the information you need to build something good.

List of axioms:
- Precepts - Urbit
- Data is better than code.
- Correctness is more important than performance.
- Deterministic beats heuristic.
- One hundred lines of simplicity is better than twenty lines of complexity.
- If your abstractions are leaking, it’s not due to some law of the universe; you just suck at abstracting. Usually, you didn’t specify the abstraction narrowly enough.
- If you avoid changing a section of code for fear of awakening the demons therein, you are living in fear. If you stay in the comfortable confines of the small section of the code you wrote or know well, you will never write legendary code. All code was written by humans and can be mastered by humans.
- If there’s clearly a right way to do something and a wrong way, do it the right way. Coding requires incredible discipline.
- The best way to get the right answer is to try it the wrong way.
- Practice tells you that things are good or bad; theory tells you why.
- Not being qualified to solve a problem is no reason not to solve it.
- If you don’t understand a system you’re using, you don’t control it. If nobody understands the system, the system is in control.

- The care and feeding of software engineers (or, why engineers are grumpy)
- In the triumvirate of software, product managers, designers, and software engineers, only the engineers are expected to turn off their creative minds and just produce.
- Both engineers and product managers tend to think, incorrectly, that product specifications or requirements are equivalent to the furniture manual from Ikea.
- This is one of the top things that make engineers grumpy: constantly shifting priorities.
- Even though many engineers will complain that product managers change their minds, almost none will account for that in their time estimates.
- Computer science programs aren’t about preparing you for the tasks you’ll face in industry.
- When there are more engineers than can be used, engineering time ends up going away from developing and towards planning, synchronization, and coordination.
- Involve engineers in the creative process
- Give engineers opportunities to be creative.
- Encourage time off.
- Let ’em code
- Express appreciation
- The Product-Minded Software Engineer, Gergely Orosz
- Great product engineers know that minimum lovable products need the right depth
- Product-minded engineers quickly map out edge cases and think of ways to reduce work on them: often bringing solutions that require no engineering work
- Engage in user research and customer support
- Bring well-backed product suggestions to the table
- Offer product/engineering tradeoffs
- 40 Lessons From 40 Years, Steve Schlafman
- If you want to make progress on the things that matter most, you need to decide who you’re going to disappoint. It’s inevitable.
- The best investment you can make is your own education. Never stop learning. The second best investment you can make is building your network through authentic and meaningful interactions. It is what you know and who you know.
- You’ll never get what you don’t ask for or actively seek out. Go for it!
- It’s not about the light at the end of the tunnel. It’s the tunnel. Show up every day and enjoy the process.
- A great teammate always puts the organization and its purpose ahead of their own self interests.
- Pick your spots. We have limited time and our brains can only process so much. Focus is key. Choose wisely.
- Every person is likely struggling with something. Be kind. Be helpful.
- On Coding, Ego and Attention
- Beginner’s mind accepts the fact that absolute knowledge is infinite and thus keeping score is a waste of time.
- Mastery is simply the accumulation of momentum, not the accumulation of knowledge.
- Dealing with ego distraction has taught me to love the problem solving process. It’s taught me to love and respect the learning process. As a result I’m more productive. I’m less anxious. I’m a better teammate. I’m a better friend and a better thinker.

- What does a great software engineer look like?
- Good sleep, good learning, good life
- 🎞 Steve Jobs: if you don’t ask for help, you won’t get very far
- Programming quotes
- Be Kind
- Being kind is fundamentally about taking responsibility for your impact on the people around you.
- It requires you be mindful of their feelings and considerate of the way your presence affects them.
- Warren Buffett Says This 1 Simple Habit Separates Successful People From Everyone Else
- The difference between successful people and really successful people is that really successful people say no to almost everything.
- How to get lucky?
- Programmers should stop celebrating incompetence, DHH
- The magic of programming is largely just things you don’t know yet.
- It’s not fine to think you shouldn’t be on some paths towards mastery, if you intend to make programming your career.
Imposter syndrome is underrated: a lot of talk goes into overcoming imposter syndrome. I say embrace self-skepticism and doubt yourself every day. In a fast-moving industry where lots of your knowledge expires every year, even the most junior people around you constantly cook up skills you don’t have; you stay competitive by applying with the determination (and even fear) of the novice. The upside of this treadmill is that every engineer is on it: just because you’re an imposter doesn’t mean that other people are more deserving than you, because they’re imposters too. You should advocate for yourself, take risks, pat yourself on the back when things go well, and, as you start to build a track record of solving problems, trust your skills and adaptability. Just make no mistake: you’re only as good as the last problem you solve.
Dan Heller, Building a Career in Software
I had learned already never to empty the well of my writing, but always to stop when there was still something there in the deep part of the well, and let it refill at night from the springs that fed it. – Ernest Hemingway

Here’s a list of good books:
- 📖 Design Patterns: Elements of Reusable Object-Oriented Software: dubbed “the gang of four”, this is almost a required reading for any developer. A lot of those are a bit overkill for Python (because everything is an object, and dynamic typing), but the main idea (composition is better than inheritance) definitely is a good philosophy.
- 📖 Patterns of Enterprise Application Architecture: learn about how database are used in real world applications. Mike Bayer’s SQLAlchemy has been heavily influenced by this book.
- 📖 Domain-Driven Design: Tackling Complexity in the Heart of Software, Eric Evans
- 📖 Clean Architecture, Robert C. Martin. Uncle Bob proposes an architecture that leverages the Single Responsibility Principle to its fullest. A great way to start a new codebase. Also checkout the clean architecture cheatsheet and this article.

- OO vs FP, Robert C. Martin, The Clean Code Blog. A pretty interesting take on the differences between OOP and FP from an expert in OOP.
- OO is not about state. Objects are bags of functions, not bags of data.
- Functional Programs, like OO Programs, are composed of functions that operate on data.
- FP imposes discipline upon assignment.
- OO imposes discipline on function pointers.
- The principles of software design still apply, regardless of your programming style. The fact that you’ve decided to use a language that doesn’t have an assignment operator does not mean that you can ignore the Single Responsibility Principle.
- Parse, don’t validate
- Use a data structure that makes illegal states unrepresentable
- Push the burden of proof upward as far as possible, but no further
- Let your datatypes inform your code, don’t let your code control your datatypes
- Don’t be afraid to parse data in multiple passes

- Incident Response at Heroku
- My Philosophy On Alerting
- Pages should be urgent, important, actionable, and real.
- Err on the side of removing noisy alerts – over-monitoring is a harder problem to solve than under-monitoring.
- Symptoms are a better way to capture more problems more comprehensively and robustly with less effort.
- Include cause-based information in symptom-based pages or on dashboards, but avoid alerting directly on causes.
- The further up your serving stack you go, the more distinct problems you catch in a single rule. But don’t go so far you can’t sufficiently distinguish what’s going on.
- If you want a quiet oncall rotation, it’s imperative to have a system for dealing with things that need timely response, but are not imminently critical.
- The Google SRE book’s chapter about oncall
- Writing Runbook Documentation When You’re An SRE
- Playbooks “reduce stress, the mean time to repair (MTTR), and the risk of human error.”
- Using a template can be beneficial because starting from a blank document is incredibly hard.
- The Curse of Knowledge is a cognitive bias that occurs when someone is communicating with others and unknowingly assumes the level of knowledge of the people they are communicating with.

- Google’s SRE book, Postmortem chapter is excellent and includes many examples.
“Let’s plan for a future where we’re all as stupid as we are today.”
– Dan Milstein
Example outline for a postmortem:
- Executive Summary
- Root cause
- Number of impacted users
- Lost revenue
- Team impact
- Root cause analysis
- E.g. with 5 whys method
- Lessons learned
- Things that went well
- Things that went poorly
- Action items (include direct links to task tracking tool)
- Tasks to improve prevention (including training)
- Tasks to improve detection (including monitoring and alerting)
- Tasks to improve mitigation (including emergency response)

Most people overestimate what they can do in 1 year and underestimate what they can do in a decade. – Bill Gates
Frankly, though, I think most people can learn a lot more than they think they can. They sell themselves short without trying. One bit of advice: it is important to view knowledge as sort of a semantic tree — make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the details/leaves or there is nothing for them to hang on to. — Elon Musk
“Experience is something you don’t get until just after you need it.” ― Steven Wright
Tell me and I forget. Teach me and I remember. Involve me and I learn. – Benjamin Franklin
Education is the kindling of a flame, not the filling of a vessel. – Socrates
That which we persist in doing becomes easier for us to do; not that the nature of the thing itself is changed, but that our power to do is increased. – Ralph Waldo Emerson
A wise man can learn more from a foolish question than a fool can learn from a wise answer. – Bruce Lee

- The Great Confusion About URIs
- A URI is a string of characters that identifies a resource. Its syntax is
<scheme>:<authority><path>?<query>#<fragment>, where only
<path>are mandatory. URL and URN are URIs.
- A URL is a string of characters that identifies a resource located on a computer network. Its syntax depends on its scheme. E.g.
- A URN is a string of characters that uniquely identifies a resource. Its syntax is
urn:<namespace identifier>:<namespace specific string>. E.g.
- A URI is a string of characters that identifies a resource. Its syntax is
- Do not log dwells on some logging antipatterns.
- Logging does not make much sense in monitoring and error tracking. Use better tools instead: error and business monitorings with alerts, versioning, event sourcing.
- Logging adds significant complexity to your architecture. And it requires more testing. Use architecture patterns that will make logging an explicit part of your contracts
- Logging is a whole infrastructure subsystem on its own. And quite a complex one. You will have to maintain it or to outsource this job to existing logging services
- Lies My Parents Told Me (About Logs)
- Logs are cheap
- I can run it better myself
- Leveled logging is a great way to separate information

- 🎞 Hammock Driven Development, Rick Hickey
- A classic talk on problem solving.
I would recommend learning:
- A compiled language (Java, C, C++…).
- A more recent language to see where the industry is going (as of writing, Go, Swift, Rust, Elixir…).
- A language that has first-class support for functional programming (Haskell, Scala, Clojure…).

- These new perspectives, these ideas and patterns — they linger, they stay with you, even if you end up in another language. And that is powerful enough to keep on learning new languages, because one of the best things that can happen to you when you’re trying to solve a problem is a change of perspective.

“A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over, beginning with a working simple system.”

- Complex systems have emergent behavior, producing epiphenomenon that only appears with sufficient scale.
- Wood’s theorem: As the complexity of a system increases, the accuracy of any single agent’s own model of that system decreases rapidly.
- The more tools and code that you add to create elements in a system, the harder it is to replicate an environment encompassing those tools and code.
- At the core of testing in production is the idea of splitting deployments (of artifacts) from releases (of features).
- Testing in Production: the hard parts, Cindy Sridharan
- The whole point of [actual] distributed systems engineering is you assume you’re going to fail at some point in time and you design the system in such a way that the damage, at each point is minimized, that recovery is quick, and that the risk is acceptably balanced with cost.
- How can you cut the blast radius for a similar event in half?
- Differentiate between deployment (0 risk) and release
- Build a deploy-observe-release pipeline
- Make incremental rollouts the norm (canaries, %-based rollouts, etc.)
- Test configuration changes just like you test code
- Default to roll back, avoid fixing forward (slow!)
- Eliminate gray failures - prefer crashing to degrading in certain cases
- Prefer loosely coupled services at the expense of latency or correctness
- Use poison tasters (isolate handling of client input)

- A good availability metric should be meaningful, proportional, and actionable. By “meaningful” we mean that it should capture what users experience. By “proportional” we mean that a change in the metric should be proportional to the change in user-perceived availability. By “actionable” we mean that the metric should give system owners insight into why availability for a period was low. This paper shows that none of the commonly used metrics satisfy these requirements…

- Deficiencies do not make you special. The older you get, the more your inability to cook will be a red flag for people.
- History remembers those who got to market first. Getting your creation out into the world is more important than getting it perfect.
- Discipline is superior to motivation. The former can be trained, the latter is fleeting. You won’t be able to accomplish great things if you’re only relying on motivation.
- You do not live in a video game. There are no pop-up warnings if you’re about to do something foolish, or if you’ve been going in the wrong direction for too long. You have to create your own warnings.
- Cultivate a reputation for being dependable. Good reputations are valuable because they’re rare (easily destroyed and hard to rebuild). You don’t have to brew the most amazing coffee if your customers know the coffee will always be hot.
