Fil v0.11.0, a memory profiler for scientists and data scientists

Your code reads some data, processes it, and uses too much memory. In order to reduce memory usage, you need to figure out: 1. Where peak memory usage is, also known as the high-water mark. 2. What code was responsible for allocating the memory that was present at that peak moment. That's exac

Online training June 11, 12: Docker packaging best practices for Python in production

You’re about to ship your Python application into production using Docker: your images are going to be critical infrastructure. And that means you need to follow best practices—if you don’t, you risk wasting quite a lot of money: * You don’t want to waste hours every week waiting for slow build

ANN: Eliot 0.9, the logging system with causality - now with journald support

Eliot 0.9 is out, with a new utility for pretty-printing log messages and native journald support [1]. You can now route Eliot logs to journald and when an error occurs easily find all logged actions that led up to that particular error, as opposed to most logging systems where this would involve

ANN: Eliot 0.8, the logging system with causality

Most logging systems can tell you what happened; Eliot tells you *why* it happened: $ python linkcheck.py | eliot-tree 4c42a789-76f5-4f0b-b154-3dd0e3041445 +-- check_links@1/started `-- urls: [u'http://google.com', u'http://nosuchurl'] +-- download@2,1/started `-- url: http://googl

Eliot 0.7: Logging for complex and distributed systems

Imagine you have a client that sends a request to a server and gets back a 500 error. What caused it? If you're using Eliot you can trace the logs across processes: $ cat server.log client.log | python eliottree.py e076ca50-9abc-44b2-95d8-85cf6956bc33 +-- main@1/started |-- process: cl

Eliot 0.6: Logging for Complex & Distributed Systems

Eliot is a logging system designed not only for simple applications but for complex applications as well, including distributed systems. Eliot supports simple structured messages but can also record a causal chain of actions happening within and across process boundaries: a logical trace of the sys

Eliot 0.5.0: Structured Logging as Storytelling

Eliot provides a structured logging and tracing system for Python that generates log messages describing a forest of nested actions. Actions start and eventually finish, successfully or not. Log messages thus tell a story: what happened and what caused it. Eliot is released by ClusterHQ
