How to Add Dropdowns on Input Fields with Bootstrap
Bootstrap is so 2017, Tailwind sucks, CSS is the only way to style – I don’t like frontend because everyone is so angry all the time. Nevertheless, a proper UI is critical to just about any application, so I must make do with the tools that are available. I’ve traditionally used React because the ecosystem…

Avoiding SQL Injection with Go
There’s a good chance if you’ve worked with Go you’ve interacted with a database of some sort and also accepted user input. Injection attacks always make it to the OWASP Top 10 (although it’s finally been dropping) – particularly SQL injection. SQL has kind of wild access control when you look at standards today; the…

goFinance – yfinance for Go!
Of all the packages available in Python’s PyPI repository, pandas is probably my most used. Coming from a data analysis and Excel-heavy background it naturally fills a lot of my needs with the language. The DataFrame really shines when you have a bunch of different data sources and it only takes minimal work to build…

Avoiding Memory Issues During Docker-Vite-React Builds
In one of my more frustrating recent evenings I had added a small feature to a react project which built and tested fine on my machine and in the CI pipeline, but refused to build on the VPS. The project would hang on the npm run build command and after 10 minutes or so (!)…

How I’m Using MSW (today, anyway)
One thing that has really changed my way of building with React is implementing tests much earlier in the development of a feature. I tend to feel almost claustrophobic working on a single laptop screen and flipping back and forth between my text editor and a browser window to see changes – this means most…

Testing Controlled React-Hook-Form Components
I recently ran into quite a bit of frustration attempting to test a component that wrapped a <Controller /> from React-Hook-Form. Most of my projects use MUI as the frontend component library so I’ve been getting used to “uncontrolling” my inputs with RHF by making my own set of inputs that can easily go into…

Adding Django-REST-Framework to Django (way after the fact)
One of my first projects in my current role was to optimize a process that involved taking a hardware design and making predictions about it. We had some old Excel sheets that would keep track of old analyses but these didn’t really enforce any structure and lots of work had to be redone each time…

Headers – The Source and Solution of All Problems
After working with Docker for a while and especially Docker Compose you start to take a lot of boring configuration for granted. I remember beginning web development and absolutely hating deploying projects to AWS instances because of the scary “reverse proxy” and setting up NGINX. Who knows how many times I googled “does flask need…

Getting the S&P 500 From Wikipedia with Python
Most of my strategies in the market are pretty basic – I don’t really like technical indicators but will use them to rank possible positions here and there. One of the best ways to reduce risk is to only look at the “good ones” so that even bad calls aren’t as bad as they could…

How to Print (to a real printer!) with Javascript
Short and sweet today – I never knew (well, never knew to look up) how to print a webpage with Javascript. Since you can do just about everything else with the window it’s not surprising, just never a use case I needed. My “discovery” came while at work and trying to debug a component that…
