"PostgreSQL and Python" Lightning Talk @EuroPython2014Henning Jacobs
PL/Python allows users to write PostgreSQL functions and procedures using Python. It enables accessing PostgreSQL data and running Python code from within SQL queries. For example, a function could query a database table, process the results in Python by accessing modules, and return a value to the SQL query. This opens up possibilities to leverage Python's extensive libraries and expressiveness to expose data and perform complex validation from PostgreSQL.
This document discusses using Python to connect to and interact with a PostgreSQL database. It covers:
- Popular Python database drivers for PostgreSQL, including Psycopg which is the most full-featured.
- The basics of connecting to a database, executing queries, and fetching results using the DB-API standard. This includes passing parameters, handling different data types, and error handling.
- Additional Psycopg features like server-side cursors, transaction handling, and custom connection factories to access columns by name rather than number.
In summary, it provides an overview of using Python with PostgreSQL for both basic and advanced database operations from the Python side.
CoffeeScript is a programming language that compiles to JavaScript. It aims to enhance JavaScript with Python- and Ruby-like syntax for cleaner code. Some key features include significant whitespace, classes and objects, functions, loops and comprehensions, and string interpolation. CoffeeScript code is compiled to equivalent JavaScript code, allowing it to integrate with existing JavaScript projects and environments.
The document discusses various querying methods in Grails including dynamic finders, where queries, detached criteria, HQL queries, and performance optimizations. It provides examples of how to use findBy, findWhere, get, count, list and other dynamic finder methods. It also covers where queries, operators, aggregate functions, collections, subqueries, bulk updates/deletes, criteria queries, and HQL queries. It discusses returning different result types and filtering query results. Lastly, it mentions caching and performance techniques.
A discussion on the upcoming new features in ES6 and how they change the way we build applications with JavaScript.
Most Notable Upcoming Changes in EcmaScript 6
Classes: Classes are now first-class citizens in ES6. The language offers support for classes ("class" keyword), constructors ("constructor" keyword) and the "extend" keyword for inheritance.
Modules: Modules provide a much needed way to segment and organize JavaScript applications in logical chunks of code. Many frameworks already provide ways to modularize large apps, but standardizing a common module structure will bring a level of interoperability between various JavaScript libraries.
Block Scoping: Scoping in JavaScript can be a confusing topic for programmers coming from more traditional Object-Oriented languages such as Java or C#. There are basically two scopes in JavaScript: global and function. Until now. With the help of the "let" keyword, ES6 enables the definition of block scopes for variables and functions.
Default Parameters: A liked feature of many other languages such as Ruby, the default parameters save endless checking of they've been passed and if they are "undefined".
Enhanced Object Literals: There is now a handy expression for property: property assignments and methods can be defined without the "function" keyword.
This document summarizes PuppetDB, Puppet Explorer, and puppetdbquery. PuppetDB is a Clojure service that stores Puppet data like facts, catalogs, and reports in a PostgreSQL backend. It allows exporting and collecting resources. PuppetDB has a rich query API to search nodes, environments, facts, catalogs, resources, and more. Puppet Explorer is a web UI that visualizes PuppetDB data using CoffeeScript and AngularJS. Puppetdbquery is a Puppet module and CLI tool for querying PuppetDB with functions, a Puppetface, hiera backend, and Ruby API. It allows querying nodes and resources with comparison, logical, and date expressions.

Maxym Kharchenko presented ways to manage Oracle databases with Python. He demonstrated a Python tool to ping multiple Oracle databases concurrently and time the execution. The tool reports the status and timing for each database pinged. Python enforces good coding practices and interfaces well with databases, APIs, and other systems. Learning Python helps develop a more Pythonic way of thinking that can improve code quality and productivity.
The document discusses using Python generators and pipelines to efficiently process streaming data. It provides examples of parsing Oracle listener logs to extract client IP addresses using generators. Generators allow data to be yielded incrementally to reduce memory usage and enable non-blocking operations compared to collecting all results at once. The document advocates defining simple generator functions that can be pipelined together to iteratively process large datasets.
The document provides an overview of new features introduced in C# 6.0, including static using, string interpolation, dictionary initializers, auto-property initializers, nameof expression, await in catch/finally blocks, null conditional operator, expression-bodied members, and extension methods used with static using. Code examples are provided to demonstrate the usage of each new feature.
This document discusses JavaScript generators and how they can be used to simplify asynchronous code. It begins with a simple generator example and then explores more complex use cases like yielding promises, error handling, and parallel processing. Generators allow long-running operations to be written in a synchronous-looking way and are useful for tasks like I/O. When combined with co-routines, they provide a clean way to write asynchronous code that looks synchronous.
The document discusses Opa, an open-source, event-based programming language for building client-server web applications. It highlights two key features of Opa - its static typing that catches errors at compile time, and its type inference capabilities. Examples are provided showing how Opa validates types and infers types to catch errors. Quotes from reviewers praise Opa for its speed of development and potential to transform web development.
