The document discusses tools used at Etsy to simplify, empower, and automate processes. It describes several homegrown tools like Virtual Madness, Deployinator, and Supergrep. It highlights that tools are a product of company culture and reflect underlying beliefs and values. At Etsy, tools manifest beliefs like "just ship", "if it moves, graph it", and optimizing for developer happiness. The talk argues that culture and tools inherently influence each other over time through implicit assumptions.

Brenden studies computational problems that are easier for people than they are for machines. He received his Ph.D. in Cognitive Science from MIT in 2014, and his M.S. and B.S. in Symbolic Systems from Stanford University in 2009. He is a recipient of the Robert J. Glushko Prize for Outstanding Doctoral Dissertation in Cognitive Science. His recent research on Bayesian Program Learning has been covered by many media outlets (New York Times, Washington Post, etc.) and was selected by Scientific American as one of the most important advances of 2016. Both cognitive science and AI can gain by studying the human solutions to difficult computational problems. Brenden's talk will focus concept learning and question asking, two problems that people solve far better than machines. People can learn a new concept from fewer examples, and then use their concepts in richer ways -- for imagination, extrapolation, and explanation, not just classification. Moreover, learning is often an active process; people can ask rich and probing questions in order to reduce uncertainty, while algorithms for active learning ask simple and stereotyped queries. He will also discuss work on program induction as a cognitive model and potential solution for extracting richer concepts from less data, with applications to learning handwritten characters and learning recursive visual concepts from examples. Brenden will end with program synthesis as a model of question asking in simple games.

Understanding Music Through Machine Learning - (Brian McFee, Moore-Sloan Fellow at New York University's Center for Data Science) Brian McFee is a Moore-Sloan Fellow at New York University's Center for Data Science. He received a B.S. degree in Computer Science from the University of California, Santa Cruz in 2003, and Ph.D. in Computer Science and Engineering from the University of California, San Diego in 2012. His work touches on various topics at the intersection of machine learning, information retrieval, and audio analysis. He is a contributor to various open source projects, and a principal developer of the librosa package for music analysis in Python. Brian will talk about how we can understand music through machine learning. Music signals share much in common with other high-dimensional data domains (e.g., images or speech), but the domain also imposes unique constraints which can inform the problem formulations and be exploited during the modeling process. In this talk, he will give two examples of recent work on statistical musical analysis: structure analysis and instrument recognition. He will provide pointers to data sets and open source implementations wherever possible.

Commodity Machine Learning - (Andreas Mueller) Recent years have seen a widespread adoption of machine learning in industry and academia, impacting diverse areas from advertisement to personal medicine. As more and more areas adopt machine learning and data science techniques, the question arises on how much expertise is needed to successfully apply machine learning, data science and statistics. Not every company can afford a data science team, and getting your PhD in biology, no-one can expect you to have PhD-level expertise in computer science and statistics. This talk will summarize recent progress in automating machine learning and give an overview of the tools currently available. It will also point out areas where the ecosystem needs to improve in order to allow a wider access to inference using data science techniques. Finally we will point out some open problems regarding assumptions, and limitations of what can be automated. Andreas is an Research Engineer at the NYU Center for Data Science, building open source software for data science. Previously, he worked as a Machine Learning Scientist at Amazon, developing solutions for computer vision and forecasting problems. He is one of the core developers of the scikit-learn machine learning library, and has co-maintained it for several years. His mission is to create open tools to lower the barrier of entry for machine learning applications, promote reproducible science and democratize the access to high-quality machine learning algorithms.

Privacy, Ethics, and Future Uses of the Social Web

At Kaggle, we’ve run hundreds of machine learning competitions and seen over 80,000 data scientists make submissions. One thing is clear: winning competitions isn’t random. We’ve learned that certain tools and methodologies work consistently well on different types of problems. Many participants make common mistakes (such as overfitting) that should be actively avoided. Similarly, competition hosts have their own set of pitfalls (such as data leakage). In this talk, I’ll share what goes into a winning competition toolkit along with some war stories on what to avoid. Additionally, I’ll share what we’re seeing on the collaborative side of competitions. Our community is showing an increasing amount of collaboration in developing machine learning models and analytic solutions. I’ll showcase examples of this and discuss how these types of collaboration will improve how data science is learned and applied.

From the tutorial description at https://us.pycon.org/2014/schedule/presentation/134/ - Description Social websites such as Twitter, Facebook, LinkedIn, Google+, and GitHub have vast amounts of valuable insights lurking just beneath the surface, and this workshop minimizes the barriers to exploring and mining this valuable data by presenting turn-key examples from the thoroughly revised 2nd Edition of Mining the Social Web. Abstract This workshop teaches you fundamental data mining techniques as applied to popular social websites by adapting example code from Mining the Social Web (2nd Edition, O'Reilly 2013) in a tutorial-style step-by-step manner that is designed specifically to accommodate attendees with very little programming or domain experience. This workshop's extensive use of IPython Notebook facilitates interactive learning with turn-key examples against a Vagrant-based virtual machine that takes care of installing all 3rd party dependencies that are needed. The barriers to entry are truly minimal, which allows maximal use of the time to be spent on interactive learning. The workshop is somewhat broadly designed and acclimates you to mining social data from Twitter, Facebook, LinkedIn, Google+, and GitHub APIs in five corresponding modules with the following memorable approach for each of them: * Aspire - Set out to answer a question or test a hypothesis as part of a data science experiment * Acquire - Collect and store the data that you need to answer the question or test the hypothesis * Analyze - Use fundamental data mining techniques to explore and exploit the data * Summarize - Present analytical findings in a compact and meaningful way Each module consists of a brief period in which each attendee will customize the corresponding notebook for the module with their own account credentials with the remainder of the module devoted to learning what data is available from the API and exercises demonstrating analysis of the data—all from a pre-populated IPython Notebook. Time will be set aside at the end of each module for attendees to hack on the code, discuss examples, and ask any lingering questions.

Designing to Learn: Creating Successful MVP Experiments

Melissa Perri

Learn what makes change for technology in business so difficult and how to motivate your employees to adopt it. What are the reasons employees do not simply embrace new technology? Resistance to change is what you’ll get without a proper user adoption strategy for your collaboration platform. Unlike IT people, business users are not necessarily thrilled about new technology, features and functionalities. Build it and they will come does not work. Most employees will need to be motivated differently to start a new way of working. How can we bend resistance to change, to change readiness? How do we find your Champions and activate them? How do employees understand when to use what app? This session will show you how to build a successful user adoption strategy.

In 2013 we had over 50 open source Chef servers running at the company. Cookbooks were being used to great benefit over previous methods, however it was getting confusing. Cookbooks were being forked and changed without the names being refactored. It was sort of a messy kitchen. We decided to align with Chef and move to the Enterprise Chef offering. Join me as I walk through many lessons learned in 2014 of getting 400+ developers from 40+ teams to learn to cook together. The result has been getting thousands of nodes into a more centrally manageable location. After I share how we got our kitchen in order, I'll share our plans and progress for 2015 of providing common building blocks of continuous delivery within a large company. https://youtu.be/EHIzjrg0fFU

Talk given at NewCrafts Paris Conference 2024 Abstract: Have you ever observed quality problems with what your team is delivering? Have you ever felt your team is learning about the actual status quo late, too late to include these insights in your next steps? Have you ever wondered how to influence change when you’re “just” a specialist on the team, maybe even felt powerless? I’ve mostly worked with people who never experienced effective collaboration across roles and specialties. How to get such a team to move toward testing throughout the delivery workflow from idea to production, on all kinds of levels, for all parts of the product, by the whole team? How to consider quality from the start and have it continuously inform our decision-making? Over the years, I’ve built a repertoire of tactics to help teams transform toward holistic testing and quality. They range from meeting people where they are to creating guidelines, pairing and many others. It’s a toolbox of approaches to try out and find the sweet spot where people start moving toward better directions together. These tactics are fallible, not all of them work in all contexts, and yet they have helped my teams get to a better place. Join this talk to get inspired to take things into your hands. Learn what you can try yourself in your context to help your team make the first steps on your journey towards holistic testing and quality. Key learnings: - Learn how you can influence team culture, no matter your role or experience level - Add team transformation tactics to your toolbox of approaches to try - Understand the many ways we can move towards holistic testing and quality

Nearly a decade ago, a small group of menders (and one maker) found community with each other at a conference and Legacy Code Rocks was born. Since then, the Legacy Code Rocks community has grown to over 1000 people, 150 podcast episodes, a weekly meetup and of course, MenderCon. In this talk, Andrea Goulet, the maker who kindled the spark, will take us back to those early days and reflect on how the bedrock of the Legacy Code Rocks community has always been creating a sense of belonging. Compassion and empathy are at the core of being a mender. Mending is caring deeply, seeing potential, and being willing to work through the frustration of making things better one small step at a time. This commitment to helping others feel seen instead of shame is why the Legacy Code Rocks community is so special — and it’s exactly why having the heart of the mender is what our world needs now more than ever.

The Mythical Technical Debt (Brooke, please, forgive me.) <This talk is designed for a technical audience> In software-intensive systems development, we often face trade-offs between speed and long-term maintainability. These trade-offs accumulate as technical debt, the hidden cost of short-term decisions that can impact future development. Technical debt goes beyond the initial choices made when creating software. It encompasses design decisions, coding practices, or anything that might hinder future development efforts. By effectively identifying and managing this debt, we can build robust and scalable software systems. In this talk, we'll explore different types of technical debt and their impact on projects. We'll delve into practical methods to identify, measure, and reduce it. Finally, we'll see how to turn technical debt into an advantage, using it as a springboard for innovation with real-world examples.

The mythical technical debt. (Brooke, please, forgive me)

Computation is increasingly constrained by power. With each advancement in the manufacturing process, a decreasing percentage of the CPU can operate at full capacity, leading to the emergence of the term 'dark silicon'. This trend necessitates techniques that utilize chip area to optimize power efficiency through specialized accelerators. The presentation will outline key concepts that led to the dark silicon such as Moore’s law and breakdown of Dennard scaling, followed by an overview of current and upcoming CPU accelerators. The focus will then shift to vector units and the specifics of vector programming. Attendees will be introduced to registers, a range of vector operations, and methods to develop branchless algorithms such as sorting networks. The session will conclude with an overview of the new Java Vector API and how it was already picked up by projects to do AI inference (Llama 2) and vector search (AstraDB and Cassandra).

Hinweis der Redaktion

Blameless postmortem - situational aspects that lead to failure - engineers that were involved accounts of: - what actions they took at what time, - what effects they observed, - expectations they had, - assumptions they had made, and their understanding of timeline of events as they occurred without fear of punishment or retribution coz this disincentives them
we’re seeing a lot of newer usages of the tool
how do you know what the parts the abstraction matter? which is why just implementing solutions that have worked elsewhere may not work in your case.
you find that some of the assumptions you made during development don’t hold in the production context anyone in the room that has written code that has always worked in production on the first try?
technical decisions you make influenced by - tools available to you - solutions that have worked in the past - commonly held beliefs for example, might want to use redis datatypes - but memcache in production - handle complexity elsewhere - past decisions will affect ones you make in the future
famous german physicist Heisenberg a lot of the decisions and thought processes of the developer are captured in the tools
so, in addition to all the utilities we’ve seen earlier, tools are a window into the culture Schein, former professor at the MIT Sloan School identifies 3 levels of culture : artifacts (visible, might be difficult to decipher), beliefs and values (ideas, goals, values, aspirations, rationalizations) that are taken up and basic underlying assumptions (unconscious, beliefs that are taken for granted, so basic that people would not even question these). want to highlight that it might be hard for newer employees to map out implicit assumptions
wanting to enable engineers to get code out: - get to see the finished product - see what they were building - get feedback ended up with continuous deployment - deploy small changesets graph of deploys per day
used when you’re deploying see if your changes affected the site make sure your feature works the way you expect it to
Solutions that worked in the past that have been transformed into shared beliefs. E for empathy - we try to be empathetic to other people, teams, functions & our users deployinator - helps us get stuff out there, statsd - made it easy for us to graph
we see how beliefs and values affect the tools you invest in example - assumptions can be different for the same thing
The part we haven’t talked much about is the implicit assumptions. New hires kind of go through this exercise: They’re trying to understand the culture - How does a particular tool work - Why things are done a particular way
To help people develop these assumptions
They go to the channel for deploying See how others are deploying, how the instructions map with what they’re seeing we have bots that manage batches of deploys Ask questions if things don’t make sense
Conversations at the watercooler can become great areas to learn and develop our implicit assumptions since we have shared context The deploy today was kinda scary, I wasn’t sure what graphs to look at…
One of the basic assumptions that is shared across Engineering
But ultimately, we learn what we see Unless you have a culture that makes learning a collaborative effort, people spending a large amount of time covering up their mistakes instead of learning from them
so if there are things you value in your organization, make them explicit this can help build shared and more correct mental models instead of having people operating in silos
Want to emphasize here the tooling and culture are really two sides of the same coin
