Everyone knows Python's basic datatypes and their most common containers (list, tuple, dict and set).
However, few people know that they should use a deque to implement a queue, that using defaultdict their code would be cleaner and that they could be a bit more efficient using namedtuples instead of creating new classes.
This talk will review the data structures of Python's "collections" module of the standard library (namedtuple, deque, Counter, defaultdict and OrderedDict) and we will also compare them with the built-in basic datatypes.
After 4 years working with MongoDB I moved to a new project using a traditional SQL database. People don't value what they have until they lose it, and even though I loved MongoDB, I never thought I would miss it so much. In this talk I will explain you why.
Session in Python Bcn Meetup, Beginners session
>> Contents:
- Python execution model
- Everything is an object
- Everything is a pointer (or a reference)
- Mutable vs. immutable objects
- Common errors
>> Code examples:
https://github.com/pablito56/pybcn-beginners
In this talk we will make a tour through the most important changes and new features in the language and its standard library, such as enums, single-dispatch generic functions, Tulip, yield from, raise from None, contextlib... And yes, we will talk about Python 3.

Do you know what’s happening each time you use the @ (at) symbol to decorate a function or class?
In this talk we are going to see how Python’s decorators syntactic sugar works under the hood.

At Telefonica PDI we are developing an internal messaging service to be used by our own products.
Sprayer is a low latency, reliable messaging system supporting delivery of messages to a single receiver, predefined group of receivers or specific list of receivers over different channels (SMS, HTTP, WebSockets, Email, Android, iOS and Firefox OS native push…). We are using Redis, MongoDB and RabbitMQ to implement Sprayer. In this talk we will review Sprayer’s architecture.
We will see for each of these technologies, why, where and for what they are used as well as some tips.
Talk done together with Javier Arias ( @javier_arilos ) at NoSQL Matters Barcelona 2013.
From Oracle to MongoDB, a real use case at Telefónica R&D
The talk will cover the use case of the Personalisation Server, a master customers profile storage for the companies of the Telefonica Group (Telefonica, O2…). It provides real-time (ReST API) and batch interfaces to update, retrieve and share customers profile. Initially the PS used Oracle, but due to scalability and cost issues we implemented a new version with MongoDB.
In the talk we will see the problems that made us move to MongoDB and all the benefits that we obtained (with real performance figures, ofc).
Right now the Oracle version is being used at UK and Ireland (aprox.
30M user profiles stored) and the NoSQL version is being deployed at Mexico (18M customers) and other Latam countries.

Hadj Ounis's most notable work is his sculpture titled "Metamorphosis." This piece showcases Ounis's mastery of form and texture, as he seamlessly combines metal and wood to create a dynamic and visually striking composition. The juxtaposition of the two materials creates a sense of tension and harmony, inviting viewers to contemplate the relationship between nature and industry.
