How to migrate from pip-tools to uv

At Caktus, many of our projects use pip-tools for dependency management. Following Tobias’ post How to Migrate your Python & Django Projects to uv, we were looking to migrate other projects to uv, but the path seemed less clear with existing pip-tools setups. Our requirements are often spread across multiple files, like this:

Why Open Source Makes Sense For Your Business Web Projects

What Is Open Source?

Open source software is publicly available code that anyone can use, modify, and improve. It’s the foundation of much of the modern internet and it’s trusted by global enterprises, startups, nonprofits, and government agencies alike.

Avoiding Timezone Traps: Correctly Extracting Date/Time Subfields in Django with PostgreSQL

Working with timezones can sometimes lead to confusing results, especially when combining Django's ORM, raw SQL for performance (like in PostgreSQL materialized views), and specific timezone requirements. I recently had an issue while aggregating traffic stop data by year, where all yearly calculations needed to reflect the 'America/New_York' (EST/EDT) timezone, even though our original data contained timestamp with time zone fields. We were using django-pgviews-redux to manage materialized views, and I mistakenly attempted to apply timezone logic to a date field that had no time or timezone information.

How to Migrate your Python & Django Projects to uv

Editor’s note: This post was updated on July 17th, 2025, to use the PATH_add hook for direnv and to recommend including uv sync --locked in your .envrc file.

DjangoCon Europe 2025 Highlights

Three Cakti recently attended DjangoCon Europe 2025 in Dublin and it was a wonderful experience! It was great to see and chat with various Django community members we usually only see once or twice a year. Beyond that, we were most impressed by the consistently high quality of the talks throughout all three days of the conference. It was a pleasure to listen to so many excellent presentations, including the lightning talks at the end of each day. Here are some of our favorite talks.

Chicago Like a Local: Hidden Gems & Unique Experiences (Part 2)

DjangoCon US 2025 is getting closer, and while we’ve covered some classic must-see spots in Part 1, there’s so much more to explore beyond the typical tourist attractions. If you’re looking for unique experiences, quirky hidden gems, and places where locals actually hang out, this guide is for you.

Tips for Tracking Django Model Changes with django-pghistory

Django and its admin interface are a big part of why Caktus uses Django, but the admin's ability to log database changes is limited. For example, it shows only changes made via the Django admin, not via other parts of the site.

At Caktus, we’re always looking for tools that help us streamline our workflows, increase productivity, and make our day-to-day tasks more efficient.

Upgrade Smarter, Not Harder: Python Tools for Code Modernization

Upgrading projects is somewhat equivalent to flossing, you know you have to do it, but rarely make time for it. After all, if the project is in active development, there are exciting new features to build. And we all know that new features > project upgrades. Well not to worry, Caktus wants to make you aware of some tools that will save you from considerable repetitive work & time while simultaneously modernizing your codebase. Combined, these tools will automate part of the upgrade process, decreasing the likelihood of neglecting parts of the codebase.
