Professional Programming - about this list

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.

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.

Must-read books

I've found these books incredibly inspiring:

There are some free books available, including:

Must-read articles

  • 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.

Other general material and list of resources

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.

  • Taking Ownership Is The Most Effective Way to Get What You Want
  • Finding Time to Become a Better Developer
  • Ten minutes a day: how Alex Allain wrote a book in less than 200 hours, by writing 10 minutes every day.
  • 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.

    • It's not fine to think you shouldn't be on some paths towards mastery, if you intend to make programming your career.
  • There’s no speed limit

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

Good judgment comes from experience. Experience comes from bad judgment.



Beyond software engineering & random


Biases don't only apply to hiring. For instance, the fundamental attribution bias also applies when criticizing somebody's code written a long time ago, in a totally different context.

Design (visual, UX, UI, typography)

I highly recommend reading The Non-Designer's Design Book. This is a pretty short book that will give you some very actionable design advices.

Articles :


Design (OO modeling, architecture, patterns, anti-patterns, etc.)

Here's a list of good books:

One of the absolute references on architecture is Martin Fowler: checkout his Software Architecture Guide.


You can use an eraser on the drafting table or a sledge hammer on the construction site. (Frank Lloyd Wright)


Design: database schema

  • A humble guide to database schema design, Mike Alche
    • Use at least third normal form
    • Create a last line of defense with constraints
    • Never store full addresses in a single field
    • Never store firstname and lastname in the same field
    • Establish conventions for table and field names.

Design: patterns

Design: simplicity

  • Simple Made Easy 🎞, Rich Hickey. This is an incredibly inspiring talk redefining simplicity, ease and complexity, and showing that solutions that look easy may actually harm your design.

Dev environment & tools


Article about tools:

  • The return of fancy tools
    • Simple tools make you think a little more
    • Drucker: "I’m not writing it down to remember it later, I’m writing it down to remember it now."
    • Frictionless note-taking produces notes, but it doesn't produce memory.

Functional programming (FP)

  • Goodbye, Object Oriented Programming
  • Functional Programming & Haskell 🎞: some good reasons to learn FP!
  • Functional Programming Fundamentals: short introduction to FP and its advantages.
  • 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
    • Avoid denormalized representations of data, especially if it’s mutable
    • Use abstract datatypes to make validators “look like” parsers
  • 🏙 Functional Programming
  • Monads in 15 minutes
  • hemanth/functional-programming-jargon: jargon from the functional programming world in simple terms




Incident response (oncall, alerting, outages, firefighting, postmortem)

  • 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.
    • This classical article has now become a chapter in Google's SRE book.
  • 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.
    • Make your content easy to glance over.
    • If a script is longer than a single line, treat it like code, and check it into a repository to be source control and potentially tested.
  • Incident Review and Postmortem Best Practices, Gergely Orosz
  • Computer Security Incident Handling Guide, NIST
  • Incident Management Resources, Carnegie Mellon University
  • Sterile flight deck rule, Wikipedia

Richard Feynman's Learning Strategy:

  1. Step 1: Continually ask "Why?”
  2. Step 2: When you learn something, learn it to where you can explain it to a child.
  3. Step 3: Instead of arbitrarily memorizing things, look for the explanation that makes it obvious.

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

A lecture has been well described as the process whereby the notes of the teacher become the notes of the student without passing through the mind of either. — Mortimer Adler

Fools learn from experience. I prefer to learn from the experience of others. — Bismark

Linux (system management)

Low-level, assembly



  • 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 <scheme> and <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. mailto:[email protected].
    • A URN is a string of characters that uniquely identifies a resource. Its syntax is urn:<namespace identifier>:<namespace specific string>. E.g. urn:isbn:9780062301239
  • Everything you need to know about DNS

Observability (monitoring, logging, exception handling)


  • 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
    • Logs are basically the same as events
    • A standard logging format is good enough
  • Logging - OWASP Cheat Sheet Series

Error/exception handling


Operating system


  • 10 modern software over-engineering mistakes
  • A good example of over-engineering: the Juicero press (April 2017)
  • You Are Not Google: the UNPHAT method to avoid cargo cult.
    • Don’t even start considering solutions until you Understand the problem. Your goal should be to “solve” the problem mostly within the problem domain, not the solution domain.
    • eNumerate multiple candidate solutions. Don’t just start prodding at your favorite!
  • Overthinking
    • 1st poison: education.
    • 2nd poison: marketing.
    • 3rd poison: ego
    • Solution: Stop trying to connect all the dots ahead of time. Embrace uncertainty and start doing.
  • Don’t Let Architecture Astronauts Scare You, Joel
    • Sometimes smart thinkers just don’t know when to stop, and they create these absurd, all-encompassing, high-level pictures of the universe that are all good and fine, but don’t actually mean anything at all.
    • Your typical architecture astronaut will take a fact like “Napster is a peer-to-peer service for downloading music” and ignore everything but the architecture, thinking it’s interesting because it’s peer to peer, completely missing the point that it’s interesting because you can type the name of a song and listen to it right away.

“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.”

— John Gall, General systemantics, an essay on how systems work, and especially how they fail..., 1975 (this quote is sometime referred as "Galls' law")

"Software engineering is what happens to programming when you add time and other programmers."

— Rob Pike, Go at Google: Language Design in the Service of Software Engineering

You can’t connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something — your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life.

— Steve Jobs


Personal knowledge management (PKM)

Personal productivity

Check out this section on my list of management resources, "Personal productivity".


  • At 31, I have just weeks to live. Here's what I want to pass on
    • First, the importance of gratitude.
    • Second, a life, if lived well, is long enough.
    • Third, it’s important to let yourself be vulnerable and connect to others.
    • Fourth, do something for others.
    • Fifth, protect the planet.
  • Life Is Not Short
    • "The most surprising thing is that you wouldn’t let anyone steal your property, but you consistently let people steal your time, which is infinitely more valuable." — Seneca

Programming languages

I would recommend learning:

  • JavaScript and maybe another interpreted language (Python, Ruby, etc.). Interpreted languages are useful for quick one-off automation scripts, and fastest to write for interviews. JavaScript is ubiquitous.
  • 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...).

A bit more reading:

There are only two kinds of languages: the ones people complain about and the ones nobody uses.

-- Bjarne Stroustrup (C++ creator)


For Python feel free to checkout my professional Python education repository.


JavaScript is such a pervasive language that it's almost required learning.

  • mbeaudru/modern-js-cheatsheet: cheatsheet for the JavaScript knowledge you will frequently encounter in modern projects.
  • javascript-tutorial: comprehensive JavaScript guide with simple but detailed explanantions. Available in several languages.

Garbage collection

Programming paradigm



  • The Rule of Three, Coding Horror
    • Every programmer ever born thinks whatever idea just popped out of their head into their editor is the most generalized, most flexible, most one-size-fits all solution that has ever been conceived.
    • It is three times as difficult to build reusable components as single use components.
    • A reusable component should be tried out in three different applications before it will be sufficiently general to accept into a reuse library.
  • Refactor vs. Rewrite
  • Tripping over the potholes in too many libraries


Releasing & deploying



Feature flags

Testing in production

  • Why We Leverage Multi-tenancy in Uber's Microservice Architecture
  • Developing in Production
    • 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)
      • Implement per-request-class backpressure
      • Have proper visibility from a client/end-user standpoint (client-side metrics)
  • Testing in Production, the safe way

  • Service Recovery: Rolling Back vs. Forward Fixing
  • How Complex Systems Fail
    • Catastrophe requires multiple failures – single point failures are not enough.
    • Complex systems contain changing mixtures of failures latent within them.
    • Post-accident attribution to a ‘root cause’ is fundamentally wrong.
    • Hindsight biases post-accident assessments of human performance.
    • Safety is a characteristic of systems and not of their components
    • Failure free operations require experience with failure.

Site Reliability Engineering (SRE)

Note: this section is only about SRE as a role. Checkout the System Architecture for more content related to reliability.


  • 📖 Site Reliability Engineering
    • Written by members of Google's SRE team, with a comprehensive analysis of the entire software lifecycle - how to build, deploy, monitor, and maintain large scale systems.


  • Graduating from Bootcamp and interested in becoming a Site Reliability Engineer?: a great collection of resources to learn about SRE.
  • Operating a Large, Distributed System in a Reliable Way: Practices I Learned, Gergely Orosz.
    • A good summary of processes to implement.
  • Production Oriented Development
    • Code in production is the only code that matters
    • Engineers are the subject matter experts for the code they write and should be responsible for operating it in production.
    • Buy Almost Always Beats Build
    • Make Deploys Easy
    • Trust the People Closest to the Knives
    • QA Gates Make Quality Worse
    • Boring Technology is Great.
    • Non-Production Environments Have Diminishing Returns
    • Things Will Always Break
  • Meaningful availability
    • 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…

Technical debt

  • TechnicalDebt, Martin Fowler.
  • Fixing Technical Debt with an Engineering Allocation Framework
    • You don't need to stop shipping features to fix technical debt
    • Communicate the business value
  • Ur-Technical Debt
    • Today, any code that a developer dislikes is branded as technical debt.
    • Ward Cunningham invented the debt metaphor to explain to his manager that building iteratively gave them working code faster, much like borrowing money to start a project, but that it was essential to keep paying down the debt, otherwise the interest payments would grind the project to a halt.
    • Ur-technical debt is generally not detectable by static analysis.


Why test:

    • Even if you don’t, someone will test your software
    • The majority of testing should be performed by development teams
