19X faster response time
At Lincoln Loop, we don’t just build web platforms from scratch and scale them to accommodate growing demand; we also dedicate ourselves to their long-term maintenance. Some of our partnerships have spanned over a decade. Let me walk you through a performance optimization journey we undertook with a large publishing platform, which serves hundreds of thousands to millions of page views daily. The Issue at Hand Over the lifespan of a platform, various infrastructure changes and design tweaks can inadvertently impact the response time. For instance, adding more content to a page or changing the ordering of the results might bog it down. Continuous monitoring is critical because it allows us to spot such regressions quickly. A live website’s behavior varies significantly from local testing. Production sites deal with multiple cache layers and handle countless concurrent requests. In contrast, during “local” development, you typically turn off these cache layers and test one endpoint at a time. Thus, when embarking on performance optimization, always base your strategy on metrics from your production environment and tackle one modification at a time. For this optimization, I utilized AWS CloudWatch for response time metrics on the load balancer and some data from Sentry’s performance … -
Team size isn't a measure of success
Most managers have internalized the idea that team growth, in and of itself, is a unalloyed good, and a sign of success. This is wrong, but it’s understandable. Team growth feels like success, but headcount by itself isn’t a measure of success. Instead, we should judge management success by impact and efficiency. -

Neomodel: Python OGM for Neo4j Extends Version Support and Moves to Neo4j Labs
We’re excited to announce that neomodel, the Python OGM (Object-Graph Mapping) library, has officially moved to the Neo4j Labs program and now supports Neo4j version 5.This development brings a host of advantages and opportunities for both the neomodel community and Neo4j users alike. In this post, we’ll cover what value this brings to the library and implies for its future.A Community-Focused LibraryNeo4j Labs is a means for exploring new technologies with Neo4j with open-source projects. It focuses on projects that see interest and adoption and manages expectations and a minimum level of quality. Many important product developments had their origins in Neo4j Labs like graph data science, the GraphQL library, the Kafka and Spark integrations, and APOC core.Neo4j Labs - Neo4j LabsLike the other Neo4j Labs projects, neomodel remains an open-source, and completely community-driven library.Joining the Neo4j Labs program implies the following:Clear expectations: Labs projects are experimental and not officially product-supported, although some of them (like NeoDash, neosemantics, and neomodel) have available Neo4j Services packages for development and support.Quality standards: To be part of Labs, you need to adhere to certain minimal quality standards, which ensures enhanced code quality (unit and integration testing), security checks, automated tooling (CI/CD), etc…Releases and … -
Docker-compose autoheal: case sensitivity
I use docker-compose quite a lot. Most of the python/django stuff we deploy is done with docker-compose (one of the two big ones is in kubernetes already). A while back I moved several "geoservers" to docker-compose. Geoserver is a web mapping server written with java/tomcat. Normally pretty stable, but you can get it to crash or to become unresponsive. So that's something for which docker's health check comes in handy. You can configure it in docker-compose itself, but I put it in our geoserver's custom Dockerfile as I was making some other modifications anyway: FROM docker.osgeo.org/geoserver:2.23.1 ... some unrelated customizations ... HEALTHCHECK --interval=20s --timeout=10s --retries=3 --start-period=150s \ CMD curl --fail --max-time 3 http://localhost:8080/geoserver/web/ || exit 1 A simple "curl" command to see if the geoserver still displays its start page. With a generous --start-period as geoserver needs quite some time to start up. Docker-compose allows for healthchecks, and displays Up (healthy) in the "state" column when you call docker-compose ps. But docker-compose doesn't actually restart failed services. For that, you need docker-autoheal as an extra service. At the core, it consists of a single shell script that asks docker if there are containers matching the filter health=unhealthy and optionally autoheal=true. … -

My reaction to the block-driven CMS blog post
My reaction to the block-driven CMS blog post This morning I read an interesting post on the Lincoln Loop blog called Building a Future-Proof Platform with Block-Driven CMS. It shouldn’t come as a surprise to those (few 😄) who know my work in the area of content management systems that the post resonated with me. I found the description of the advantages of block-based CMS editing very clear and I like the emphasis on structuring data well so that it can be reused for multiple distribution channels. Of course django CMS isn’t the only way to implement a block-driven CMS using Django. Since its inception FeinCMS was always the smaller, faster and nimbler counterpart to it, achieving the same basic goals with a fraction of the code and maintenance headaches. django CMS always seems to trail the official releases of Django. django-content-editor and feincms3 are almost always compatible with the development version of Django by way of running the tests with the main branch as well. This allows me to be an early adopter of upcoming Django releases with a software stack that’s already well tested, or also to report bugs to the Django project itself. All that probably wouldn’t … -
Migrating a Django Project from a GPU to a Convenience Image on CircleCI
Recently we learned that as of September 30th, 2023 several linux images will be deprecated, including the one we used, ubuntu-2004:202111-02. Therefore, after September 30th, our pipelines would have failed. To avoid this, we switched several machines in our Django project from Ubuntu GPU images to convenience images; This writing details that switch. Updating a GPU machine image can be a bit tricky. One must ensure that the base image language version and project language version match. Otherwise, updating the GPU image version might result in inadvertently updating the base language version. Resulting, for instance, in a project that uses Python 3.9 and an image (in case of a test image) running those tests in Python 3.11. This might result in issues. To avoid having to constantly update our image, to ensure that our image version is what we intend it to be, and to embrace CircleCI’s current technology we migrated to a next-generation convenience image. According to CircleCI, convenience images are “extensions of official Docker images, and include tools especially useful for CI/CD.” The next-generation convenience images were “built from the ground up with CI, efficiency, and determinism in mind.” CircleCI claims that the next-generation images have a faster … -

Weeknotes (2023 week 33)
Weeknotes I’m not sure if I should call these posts weeknotes when I see the posting schedule, but oh well. Keep expectations up but also practice forgiveness when not meeting them, it’s fine really. py_modules using hatchling I converted speckenv and django-sitemaps after finding the following very helpful post on packaging projects consisting of Python modules without any packages: Packaging of single Python module projects with Hatch/Hatchling. It’s very easy in hindsight, but that’s basically always the case. The relevant part is including the files in the build: [tool.hatch.build] include = [ "speckenv.py", "speckenv_django.py", "speckenv_django_patch.py", ] That’s all. django-debug-toolbar and tracing the cause of DB queries in an async world I have also started investigating what would have to be changed in django-debug-toolbar to make it fully support async Django. We currently patch Django’s database cursors per thread, which works fine in sync Django land to attribute SQL queries to a particular request/response cycle. Since async Django executes DB queries in a thread pool executor and the rest of the work happens inside awaitables (async land) I don’t immediately see a way how we could do the same thing. It doesn’t seem possible to find out which task spawned another … -
