Extractingrails
The document discusses extracting the Ruby on Rails framework from the Basecamp project at 37signals. It describes how Rails was built to fit the constraints of a small team with limited resources. Rails focuses on liberating good ideas and changing contexts while retaining core insights in order to appeal to smaller teams and companies rather than large enterprises.
Worldofresources
This document discusses CRUD (Create, Read, Update, Delete) operations and how they are commonly implemented in web applications using the Ruby on Rails framework. It argues that CRUD operations are often seen as simplistic or unworthy but they provide consistency, simplicity, and discoverability. CRUD is a design technique rather than a goal, and there are ways to implement CRUD operations beyond just "things" like relations, events, and states.
Programminghappiness
This document discusses motivation and conventions in programming. It advocates optimizing for programmer happiness by using conventions over configuration and doing things the right way. Conventions create invitations, opportunities, and expectations that lead to more beautiful code. Constraints from conventions are said to be liberating. The document promotes using Ruby on Rails frameworks as it scales well and provides solutions like testing and migrations.
Cheap'n'easy usability
This document provides guidance on how to conduct low-cost or "discount" usability testing. It notes that usability testing does not require specialized expertise and can be done by following some basic steps. Such testing involves observing users complete simple tasks on a website or prototype and noting where they succeed or fail. While confronting at times, these tests can help identify usability issues and save costs compared to not testing. The document recommends starting with 5-7 test participants and observing each other conduct tests before analyzing the results for common problems and user feedback.
The Experience Canvas: How to Use a Core Tool from the Experience-Driven Play...
The document introduces the Experience Canvas, a tool used by teams at Atlassian to facilitate design thinking and collaboration. The Experience Canvas provides a framework to outline hypotheses, problems, ideas, prototypes, testing and more for any given project. An example is provided showing how a team used the Experience Canvas to address the "blank page problem" users encounter when first opening Confluence. The document encourages readers to use the Experience Canvas playfully with their own teams to drive innovation.

A Scaleup is not a Startup
What you do to get Product Market Fit, should be very different to what you do afterwards in order to scale. Startups are about putting out fires, scaleups are about lighting them.
Startup perfomance
This document provides advice for startup leaders on how to effectively present their big ideas. It recommends beginning with a short teaser to describe the key idea. The presenter should then show the problem by describing the urgent need. Financial aspects like profit should be explained. Slides should use graphs and schemes rather than tables for easy perception. The presenter should speak into the mic and involve the audience. They should share warm words about their team and ask for help rehearsing. The presentation should end with a bright final message.

Review processes as the last step in quality assurance workflows are “notorious for causing delays and frustrations”.

10 Badass Quotes about Customer Feedback from Product and CX Pros
One of the difficult things about dealing with customer feedback, and the idea of putting the customers first, is that there is not a clear process that can help all type of businesses become more customer focused. Every business has to find their specific way to go about it. It is a creative process that involves people, and people are messy. A good place to start is to expose ourselves to different thinking and practices from those who have succeeded in building a culture where both the vision of business and the customer needs are aligned.

Humans by the hundred
This document discusses how scaling teams to support big data growth at Yelp can negatively impact deployment speed due to an exponential increase in the probability of failures as the number of developers increases. It proposes service-oriented architecture and focusing on mean time to recovery rather than just preventing failures as ways to mitigate these risks and maintain rapid iteration. Continuous delivery, reliable but not exhaustive testing, and treating all processes as distributed are also recommended to support scaling teams while preserving deployment speed.

A Holistic View of Complex Systems and Organizational Change
One of the most misunderstood concepts in the agile community, complexity is often used to explain why we can’t predict anything or why there are no rules we can follow. Ironically, it is exactly this attitude that allows complexity to work against us. Al Shalloway discusses the true nature of complex systems, why we must deal with them in a holistic manner, and ways to evaluate structural and organizational changes to manage this complexity. Unfortunately, most agile implementations take an incremental, piecemeal approach to change, ignoring complexity. Although this approach causes problems that are attributed to the fact that we have a complex system, in reality these challenges are due to the way we are dealing with the pieces individually. Al describes the patterns of effective organizational change management and explains how understanding the true nature of complex systems can be used to lead organizational change―particularly at scale.

WordCamp Nashville 2016: The promise and peril of Agile and Lean practices
Michael Toppa gave a presentation on the promise and perils of Agile and Lean practices. He discussed how adopting these practices can help address common project problems like unrealistic expectations that compromise quality, multitasking that reduces productivity, and lack of feedback that leads to building the wrong products. However, going all-in with Agile through methods like Scrum requires major changes all at once, while adopting Lean through Kanban allows for more incremental evolution. Successful implementations inspect and adapt processes, rather than relying on superficial or misapplied changes.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI support
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
