Scaling Etsy: What Went Wrong, What Went Right

Ross Snyder

In this exciting and informative talk, presented at PgConf Sillicon Valley 2015, Konstantin cut through the theory to deliver a clear set of practical solutions for scaling applications atop PostgreSQL, eventually supporting millions of active users, tens of thousands concurrently, and with the application stack that responds to requests with a 100ms average. He will share how his team solved one of the biggest challenges they faced: effectively storing and retrieving over 3B rows of "saves" (a Wanelo equivalent of Instagram's "like" or Pinterest's "pin"), all in PostgreSQL, with highly concurrent random access. Over the last three years, the team at Wanelo optimized the hell out of their application and database stacks. Using PostgreSQL version 9 as their primary data store, Joyent Public Cloud as a hosting environment, the team re-architected their backend for rapid expansion several times over, as the unrelenting traffic kept climbing up. This ultimately resulted in a highly efficient, horizontally scalable, fault tolerant application infrastructure. Unimpressed? Now try getting there without the OPS or DBA teams, all while deploying seven times per day to production, with an application measuring 99.999% uptime over the last 6 months.

Machine Learning and Data Science are the hot technologies everyone is chasing this year, but sharing Machine Learning solutions is more complicated than simple source control. How do you share the process that allowed you to arrive at your solution? How do you effectively communicate between Data Scientists and Developers? How do I make it pretty so that I can present the work to non-technical stakeholders? This talk answers these questions using Azure Notebooks. We will walk through a real example of a Jupyter Notebook, its features and I how I created it. The topics covered include: • What are Azure Notebooks? How do they fit into the Azure Ecosystem? • What is Jupyter? What are it's strengths and weaknesses? • Mixing code snippets and execution results • Data Visualization for presentation and analysis • Markdown for exposition and formatting • Sharing and Source Control You'll leave with an understanding of Jupyter and Azure Notebooks and understand how to apply Azure Notebooks to real-world problems. TARGET AUDIENCE: Developers, Architects, Business Analysts, Data Scientists, Data Developers

"Why should we write our tests first? Isn't that going to slow my development?" "What? Assigning a single task to 2 developers? How is that efficient? What a waste of resources!" "Look, in the perfect world your advises are great, but I have a project to finish here." In this talk Marcello explores efficiency in contrast to effectiveness. He looks into how practices, traditionally accepted as efficient, sometimes turn out to be less effective than a few "impractical" things he has come across.

How resolve Gem dependencies in your code?

Hiroshi SHIBATA

It has been said that one should code as if the person maintaining the code is a violent psychopath who knows where you live. But why do we work with psychopaths? That question unfortunately cannot be answered in this presentation. However, we can shed some light on how to code for readability hopefully avoiding the problem altogether. Readable code is about a lot more than producing beautiful code. In fact, it has nothing really to do with the beauty of the code and everything to do with the ability to quickly understand what the code does. In this presentation we will discuss why readable code is so important. We will cover six commonly reoccurring patterns that made code hard to read, why they occur, and how they can easily be avoided: * Deep Nesting * Unnecessary Generalization * Ambiguous Naming * Hard to Follow Flow of Execution * Code Style vs. Individualism * Code Comments These concepts may be applied to any programming language.

Sara Mae O’Brien Scott and Tatiana Baquero Cakici, Senior Consultants at Enterprise Knowledge (EK), presented “AI Fast Track to Search-Focused AI Solutions” at the Information Architecture Conference (IAC24) that took place on April 11, 2024 in Seattle, WA. In their presentation, O’Brien-Scott and Cakici focused on what Enterprise AI is, why it is important, and what it takes to empower organizations to get started on a search-based AI journey and stay on track. The presentation explored the complexities of enterprise search challenges and how IA principles can be leveraged to provide AI solutions through the use of a semantic layer. O’Brien-Scott and Cakici showcased a case study where a taxonomy, an ontology, and a knowledge graph were used to structure content at a healthcare workforce solutions organization, providing personalized content recommendations and increasing content findability. In this session, participants gained insights about the following: Most common types of AI categories and use cases; Recommended steps to design and implement taxonomies and ontologies, ensuring they evolve effectively and support the organization’s search objectives; Taxonomy and ontology design considerations and best practices; Real-world AI applications that illustrated the value of taxonomies, ontologies, and knowledge graphs; and Tools, roles, and skills to design and implement AI-powered search solutions.

What is a good lead in your organisation? Which leads are priority? What happens to leads? When sales and marketing give different answers to these questions, or perhaps aren't sure of the answers at all, frustrations build and opportunities are left on the table. Join us for an illuminating session with Cian McLoughlin, HubSpot Principal Customer Success Manager, as we look at that crucial piece of the customer journey in which leads are transferred from marketing to sales.

The presentation explores the development and application of artificial intelligence (AI) from its inception to its current status in the modern world. The term "artificial intelligence" was first coined by John McCarthy in 1956 to describe efforts to develop computer programs capable of performing tasks that typically require human intelligence. This concept was first introduced at a conference held at Dartmouth College, where programs demonstrated capabilities such as playing chess, proving theorems, and interpreting texts. In the early stages, Alan Turing contributed to the field by defining intelligence as the ability of a being to respond to certain questions intelligently, proposing what is now known as the Turing Test to evaluate the presence of intelligent behavior in machines. As the decades progressed, AI evolved significantly. The 1980s focused on machine learning, teaching computers to learn from data, leading to the development of models that could improve their performance based on their experiences. The 1990s and 2000s saw further advances in algorithms and computational power, which allowed for more sophisticated data analysis techniques, including data mining. By the 2010s, the proliferation of big data and the refinement of deep learning techniques enabled AI to become mainstream. Notable milestones included the success of Google's AlphaGo and advancements in autonomous vehicles by companies like Tesla and Waymo. A major theme of the presentation is the application of generative AI, which has been used for tasks such as natural language text generation, translation, and question answering. Generative AI uses large datasets to train models that can then produce new, coherent pieces of text or other media. The presentation also discusses the ethical implications and the need for regulation in AI, highlighting issues such as privacy, bias, and the potential for misuse. These concerns have prompted calls for comprehensive regulations to ensure the safe and equitable use of AI technologies. Artificial intelligence has also played a significant role in healthcare, particularly highlighted during the COVID-19 pandemic, where it was used in drug discovery, vaccine development, and analyzing the spread of the virus. The capabilities of AI in healthcare are vast, ranging from medical diagnostics to personalized medicine, demonstrating the technology's potential to revolutionize fields beyond just technical or consumer applications. In conclusion, AI continues to be a rapidly evolving field with significant implications for various aspects of society. The development from theoretical concepts to real-world applications illustrates both the potential benefits and the challenges that come with integrating advanced technologies into everyday life. The ongoing discussion about AI ethics and regulation underscores the importance of managing these technologies responsibly to maximize their their benefits while minimizing potential harms.
