The Problem with Decision Trackers

Posted by Molly on Dec. 7, 2017, 10:16 a.m.

For project managers, one of the commonalities across industries is decision making. Every project requires a number of decisions, both big and small, that will inevitably come back to bite someone.

Performing an operation at a given average throughput

Posted by gavin on Oct. 25, 2017, 2:03 p.m.

A programming task I've often needed, especially while writing benchmarking code, is to perform an operation at a given number of times per second. For example, I want to see how a queue system performs under a load of 10 messages per second. To do this, I write a script to generate messages at the given rate. What is the correct pattern to ensure it runs at the correct rate, when the time to execute each iteration of the loop is variable, due to differences in how long it takes to construct the message or scheduling delays?

Implementing a semaphore with Django and Postgres

Posted by gavin on Sept. 12, 2017, 11:12 a.m.

Recently I was working on a project that accesses a third-party webservice. The service does not handle concurrency well, and crashes if you send more than a few requests at the same time. To prevent it from getting overloaded, I implemented a semaphore with Postgres and Django.
