Clean code is not the goal - working software is

Oct 30, 20121 like1,431 views

This document discusses that clean code is not the goal, but rather working software is the goal. It argues that many popular software projects like WordPress and Drupal generate significant value despite not being considered clean code. Clean code should help deliver tangible value and shipping working software, not be an end in itself. Infrastructure, workflows, communication, and leadership should also be clean to help deliver value.

CLEAN CODE IN 10 OR LESS
BUZZWORDS
Readable
Structured
Tested
Pretty
Documented
Well designed
Self explanatory
SOLID
Concise
Well architected

SO WHAT ABOUT CLEAN
CODE?
You maybe came here to hear about clean code

AND WE KILLED IT
When people say "clean" do you think of:
Wordpress?
Drupal?
Typo?
phpBB?
Magento?

WHY NOT?
Estimated value generated by Drupal in 2012 is about 7gazilion Dollar.

CLEAN IS MORE THAN JUST PRETTY

These projects don't generate that value by being clean, well
structured or easily maintainable but they work, you can get
somewhere quickly, validate ideas, deliver.

SO CLEAN CODE IS WORTHLESS?
Everything you do should help you to continously deliver tangable
value!

AND IF IT'S NOT HELPING?
Communicate it as waste and get rid of it

CLEAN THINGS
Code
Infrastructure
Workflows (Processes)
Communication
Leadership

WHAT IS "CODE"?
Code is something that software engineers produce

SO WHAT DO ENGINEERS PRODUCE?
DESIGN DOCUMENTS!
Architects produce blue prints.
Houses are build from them.
Electrical engineers produce circut board diagramms.
Boards are build with those designs imprinted.

WHAT DO WE PRODUCE?
We produce source code.
Software is produced using that blue print.

SOURCE CODE IS NOT THE PRODUCT
We don't deliver source code
Source code is not what we get paid for
It's the final design document

WE DELIVER WORKING SOFTWARE
Compile the source
Add the asserts
Patches and migration pathes
Deployment

SOFTWARE IS SPECIAL
Building is really cheap
Designing is really expensive

MAINTAINING SOFTWARE IS ALSO SPECIAL
Since building is cheap you can change stuff easily

DO YOU NEED YOUR DESIGN
DOCUMENTS TO CHANGE?

"BUILD THE RIGHT IT"
And then build "it" right

London DevOps Meetup - PaaS as a platform for devopsJeremy Brown

24 Months - A DevOps RetrospectiveSam McLeod

Infoxchange was facing infrastructure and cultural issues in 2012, with aging servers, fragile application deployments, and a blame culture. By 2014, through initiatives like eliminating technical debt, modernizing infrastructure with Docker and Puppet, integrating development and operations teams, and facilitating frequent production deployments, Infoxchange transformed its platform and culture to better support its mission of delivering technology for social justice. The changes enabled Infoxchange to reduce firefighting, increase deployment frequency from monthly to daily, and have happier and more collaborative Dev and Ops teams.

Devops is (not ) a buzzwordMiguel Fonseca

DevOps aims to break down silos between development and operations teams through collaboration, automation, and continuous delivery. It addresses issues with traditional software development like long release cycles, bugs in production, and conflicts between teams. DevOps promotes integrating development and operations, establishing agile workflows, automating testing, treating infrastructure as code, and monitoring applications in production. While sometimes seen as a buzzword, DevOps is a philosophy that can help organizations reduce risks and improve their ability to rapidly deliver value to customers.

The way Devs do OpsMiguel Fonseca

The document discusses the relationship between developers and operations in a DevOps environment. It notes that the author has experience both as an operations engineer and developer. Some key aspects of DevOps covered include having a culture of collaboration between dev and ops, using the same tools and languages, treating all problems as shared responsibilities, and establishing modern software project foundations like continuous integration/delivery pipelines. The author is happy to answer any questions about DevOps.

Software architecture in a DevOps worldBert Jan Schrijver

The document discusses how software architects can work with DevOps teams by applying DevOps principles to software architecture. It defines DevOps as development and operations engineers working together across the entire product lifecycle. Key DevOps principles that can be applied to architecture include focusing on customer needs, enabling automation, ensuring collaboration between teams, prioritizing continuous improvement through experimentation and feedback, and taking an approach of gradual changes. The document argues that by following these principles, architects can help their organizations build and release better quality software more quickly.

Rapidly prototyping games_FITC Amsterdam_2013Wooga

This document compares and contrasts several game development engines and frameworks. Unity is mentioned as being easy for artists and animators to use, allowing deployment to web and mobile, and having a simple asset pipeline. However, it has performance limitations and lacks low-level device APIs. Unreal Engine is described as performant and game-oriented, deploying to Android and iOS, but its asset pipeline needs work and UI can be difficult. Godot deploys to many platforms and has good 3D workflow with live coding, but 2D is less straightforward and it does not deploy to web. The document recommends small team sizes, keeping projects simple, user testing early, and being willing to iterate and change ideas that are not working.

The history of Tibet had a significant impact on shaping Tibetan culture. Tibetan Buddhism became the dominant religion after it was introduced in the 7th century. Over time, religion and politics became intertwined as the Dalai Lama rose to power. When China conquered Tibet in the 1950s, it challenged Tibetan culture and religion but also invested in infrastructure to strengthen its control. Tibetan culture is now influenced by both religion and material interests.

This document provides guidance for agents, surveyors, ship managers, and brokers on properly signing off documents to avoid contracting as a principal when intending to act as an agent. Key recommendations include always signing off as "agent only" or "broker only" and for the name of the principal to be clearly disclosed. Failure to do so risks the agent being found personally liable under the contract if the principal cannot meet their obligations. The document outlines several cases where agents failed to sign off properly and faced claims as a result.

Object Pascal Clean Code Guidelines Proposal (at EKON 22)Arnaud Bouchez

This EKON 22 conference was not about the code formatting - where we put the “begin” keyword is mostly a matter of taste and convention. But it shows how the object pascal strong typing system, and its language expressiveness may help writing clean(er) code. Abstract SOLID principles could help define the class and services hierarchy. After years of server-side coding, we propose some practical guidelines for cleaner object pascal programming, to reduce technical debt, and allow cross-platform/cross-compiler support.

Alfresco day madrid john newton - key noteAlfresco Software

The document discusses the evolution of IT from centralized systems controlled by vendors to more open and social systems. It describes how user needs and expectations changed, driving demand for more consumer-like applications in the enterprise. Systems of engagement emerged to meet this demand. Content became more diverse and social features like collaboration and sharing became important. The boundaries between systems of record and systems of engagement blurred as both were needed. Open source, cloud computing, and social aspects became more prominent. Alfresco is positioned as an open source social content management platform to address these trends.

This document discusses the importance of clean code and naming conventions. It argues that naming everything properly, including namespaces, classes, functions and variables, is crucial because people will read code far more than they write it. Descriptive names communicate intent and enable code to be understood without comments. Common naming issues like 'Util' classes and generic names are addressed. The document emphasizes that functions should be named for what they do, with boolean functions starting with 'has' or 'is'. Setters should not return anything other than the object or null.

TrustArc Webinar: Cross-Border Data Transfers in 2025TrustArc

In 2025, cross-border data transfers are becoming harder to manage—not because there are no rules, the regulatory environment has become increasingly complex. Legal obligations vary by jurisdiction, and risk factors include national security, AI, and vendor exposure. Some of the examples of the recent developments that are reshaping how organizations must approach transfer governance: - The U.S. DOJ’s new rule restricts the outbound transfer of sensitive personal data to foreign adversaries countries of concern, introducing national security-based exposure that privacy teams must now assess. - The EDPB confirmed that GDPR applies to AI model training — meaning any model trained on EU personal data, regardless of location, must meet lawful processing and cross-border transfer standards. - Recent enforcement — such as a €290 million GDPR fine against Uber for unlawful transfers and a €30.5 million fine against Clearview AI for scraping biometric data signals growing regulatory intolerance for cross-border data misuse, especially when transparency and lawful basis are lacking. - Gartner forecasts that by 2027, over 40% of AI-related privacy violations will result from unintended cross-border data exposure via GenAI tools. Together, these developments reflect a new era of privacy risk: not just legal exposure—but operational fragility. Privacy programs must/can now defend transfers at the system, vendor, and use-case level—with documentation, certification, and proactive governance. The session blends policy/regulatory events and risk framing with practical enablement, using these developments to explain how TrustArc’s Data Mapping & Risk Manager, Assessment Manager and Assurance Services help organizations build defensible, scalable cross-border data transfer programs. This webinar is eligible for 1 CPE credit.

Dark Dynamism: drones, dark factories and deurbanizationJakub Šimek

Startup villages are the next frontier on the road to network states. This book aims to serve as a practical guide to bootstrap a desired future that is both definite and optimistic, to quote Peter Thiel’s framework. Dark Dynamism is my second book, a kind of sequel to Bespoke Balajisms I published on Kindle in 2024. The first book was about 90 ideas of Balaji Srinivasan and 10 of my own concepts, I built on top of his thinking. In Dark Dynamism, I focus on my ideas I played with over the last 8 years, inspired by Balaji Srinivasan, Alexander Bard and many people from the Game B and IDW scenes.

AI and Meaningful Work by Pablo Fernández VallejoUXPA Boston

As organizations rush to "put AI everywhere," UX professionals find themselves at a critical inflection point. Beyond crafting efficient interfaces that satisfy user needs, we face a deeper challenge: how do we ensure AI-powered systems create meaningful rather than alienating work experiences? This talk confronts an uncomfortable truth: our standard approach of "letting machines do what machines do best" often backfires. When we position humans primarily as AI overseers or strip analytical elements from roles to "focus on human skills," we risk creating technically efficient but professionally hollow work experiences. Drawing from real-world implementations and professional practice, we'll explore four critical dimensions that determine whether AI-augmented work remains meaningful: - Agency Level: How much genuine control and decision-making scope remains? - Challenge Dimension: Does the work maintain appropriate cognitive engagement? - Professional Identity: How is the core meaning of work impacted? - Responsibility-Authority Gap: Do accountability and actual control remain aligned? Key takeaways of this talk include: - A practical framework for evaluating AI's impact on work quality - Warning signs of problematic implementation patterns - Strategies for preserving meaningful work in AI-augmented environments - Approaches for influencing implementation decisions This session assumes familiarity with organizational design challenges but focuses on emerging patterns rather than technical implementation. It aims to equip UX professionals with new perspectives for shaping how AI transforms work—not just how efficiently it performs tasks.

Harmonizing Multi-Agent Intelligence | Open Data Science Conference | Gary Ar...Gary Arora

This deck from my talk at the Open Data Science Conference explores how multi-agent AI systems can be used to solve practical, everyday problems — and how those same patterns scale to enterprise-grade workflows. I cover the evolution of AI agents, when (and when not) to use multi-agent architectures, and how to design, orchestrate, and operationalize agentic systems for real impact. The presentation includes two live demos: one that books flights by checking my calendar, and another showcasing a tiny local visual language model for efficient multimodal tasks. Key themes include: ✅ When to use single-agent vs. multi-agent setups ✅ How to define agent roles, memory, and coordination ✅ Using small/local models for performance and cost control ✅ Building scalable, reusable agent architectures ✅ Why personal use cases are the best way to learn before deploying to the enterprise

Crazy Incentives and How They Kill Security. How Do You Turn the Wheel?Christian Folini

Everybody is driven by incentives. Good incentives persuade us to do the right thing and patch our servers. Bad incentives make us eat unhealthy food and follow stupid security practices. There is a huge resource problem in IT, especially in the IT security industry. Therefore, you would expect people to pay attention to the existing incentives and the ones they create with their budget allocation, their awareness training, their security reports, etc. But reality paints a different picture: Bad incentives all around! We see insane security practices eating valuable time and online training annoying corporate users. But it's even worse. I've come across incentives that lure companies into creating bad products, and I've seen companies create products that incentivize their customers to waste their time. It takes people like you and me to say "NO" and stand up for real security!
