MongoDB is one of the most popular databases these days and there are a few reasons for such popularity. One of these reasons is the excellent integration with different programming languages and development frameworks.
In the case of Python we take it a few notches up (native use of dictionaries, integration with asynchronous libraries (twisted, gevent), good support for web frameworks like django, flask, bottle ... (mongoengine anyone?).
This talk is about the several different projects that we support, the way to effectively use Python and MongoDB together and a few other improvements and announcements.
This presentation will demonstrate how you can use the aggregation pipeline with MongoDB similar to how you would use GROUP BY in SQL and the new stage operators coming 3.4. MongoDB’s Aggregation Framework has many operators that give you the ability to get more value out of your data, discover usage patterns within your data, or use the Aggregation Framework to power your application. Considerations regarding version, indexing, operators, and saving the output will be reviewed.

Back to Basics Webinar 5: Introduction to the Aggregation FrameworkMongoDB
This is the fifth webinar of a Back to Basics series that will introduce you to the MongoDB database. This webinar will introduce you to the aggregation framework.
These are slides from our Big Data Warehouse Meetup in April. We talked about NoSQL databases: What they are, how they’re used and where they fit in existing enterprise data ecosystems.
Mike O’Brian from 10gen, introduced the syntax and usage patterns for a new aggregation system in MongoDB and give some demonstrations of aggregation using the new system. The new MongoDB aggregation framework makes it simple to do tasks such as counting, averaging, and finding minima or maxima while grouping by keys in a collection, complementing MongoDB’s built-in map/reduce capabilities.

MongoDB World 2019: Exploring your MongoDB Data with Pirates (R) and Snakes (...MongoDB
Does exploring data excite you? Do you use Python or R as your language of choice for data analysis? Does your job title include the term Data Analyst? If you answered yes to any of those questions, then the Exploring Your MongoDB Data with Pirates and Snakes is the session for you! MongoDB Developer Advocate Ken Alger will show the suggested method for using dataframe structures in R and Python with your MongoDB data. He’ll show the code for best practices in both languages to move your array based MongoDB data into the popular fast, flexible, and expressive dataframes used for data analysis in these prominent programming languages.
Webinar: Getting Started with MongoDB - Back to BasicsMongoDB
Part one an Introduction to MongoDB. Learn how easy it is to start building applications with MongoDB. This session covers key features and functionality of MongoDB and sets out the course of building an application.
MongoDB offers two native data processing tools: MapReduce and the Aggregation Framework. MongoDB’s built-in aggregation framework is a powerful tool for performing analytics and statistical analysis in real-time and generating pre-aggregated reports for dashboarding. In this session, we will demonstrate how to use the aggregation framework for different types of data processing including ad-hoc queries, pre-aggregated reports, and more. At the end of this talk, you should walk aways with a greater understanding of the built-in data processing options in MongoDB and how to use the aggregation framework in your next project.

Uma equipe de apenas 14 engenheiros (junho de 2017) cuida da Infraestrutura do principal banco de dados do Facebook. Toda ação no Instagram, Messenger, WhatsApp e claro, no FB, passa direta ou indiretamente pela infra de dezenas de milhares de servidores que rodam MySQL.
A linguagem usada pela equipe e por trás de toda a automação é Python. Nessa palestra, vamos mostrar como a linguagem possibilitou que chegássemos nessa escala, passando pela evolução, desafios e futuro:
Interfaces “tipadas” com Thrift;
Empacotamento através do Buck;
Type Checking com MyPy;
Asyncio para novos serviços;
Debugging com gdb 7 e pudb;
Além disso, durante a palestra, serão discutidas algumas decisões relacionadas a DevOps que podem inspirar soluções em outros ambientes: gerenciamento de dezenas de milhares de servidores e banco de dados, backups e restores contínuos, schema migrations, entre outros.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
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.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
