F#un with Advent Of Code 2024 day 1

I may not be the most qualified, but I’m having a lot of F#un with Advent of Code 2024 (AOC)! It’s incredible how F# enables you to focus on problem-solving, making the experience even more enjoyable.

I had heard about AOC in the past but always dismissed it, thinking I was too busy and should prioritize solving “real-world” problems. However, tackling these challenges has proven to be a great learning experience—and, as it turns out, quite addictive once you earn that first gold star! ⭐

F# Compilation Speed

Just recently, I was watching the fsharpConf2023. There was a very interesting talk from the CEO of Darklang, Paul Biggar. Darklang was originally created using OCaml. Later on they decided to switch to F# and the talk is about their experience with F#. Paul Biggar specifically discussed the goods and the bads of F# as a language to use in production. One of the comments that stood out to me was the compilation speed of F#.

Feliz React components

I have been looking for a best practice to create a major single page application using the excellent Feliz library. I also heavily borrowed ideas from a book by the author of Feliz, Zaid Ajaj. The application in mind is intended to be the Dutch National Pediatric Emergency app used for acute interventions in pediatric medical emergencies. The main purpose of the application is to provide all calculations necessary based on age and weight of the patient.

Hoe kunnen wij kritisch zieke kinderen (nog) optimaal(-er) behandelen over 5 jaar?

Waarom?

Het ergste wat een ouder kan overkomen is dat zijn/haar kind kritisch levensbedreigend ziek wordt. De Kinder IC is dan vaak de laatste strohalm. Gelukkig wordt de behandeling steeds beter op de IC, maar daarmee worden ook de uitdagingen steeds groter. Een zeer belangrijke uitdaging daarbij is groeiende complexiteit van zorg die geleverd moet worden aan toenemend complexe patiënten.

The case for a Generalized Computerized Provider Order Entry system: GenPRES

What is the problem?

To Err is Human. This is how a landmark paper from 2000 starts, recognizing that “the problem is not bad people in health care–it is that good people are working in bad systems that need to be made safer“​*​. The consequences of errors can be described by adverse events. Adverse events that are related to medication and or drug/fluid incidents constitute about 20% of all types of adverse events, which makes this the second most common type of adverse event​†​.

PICURED Pediatric Intensive Care Research Database

At the PICU (Pediatric Intensive Care Unit) of the University Medical Center Utrecht, we have been working the last years to make the data from our PDMS (Patient Data Management System) available for research. This has resulted in a multilayered system with generic possibilities to extract data and transform those data into a convenient flat table format (as described in a previous post).

Feliz indentation and Fantomas

Indentation is important in F#, as it defines the code blocks and the separate code elements. Using Feliz to define a view, in a Fable.React application, the indentation matters just as much, and even more.

Fantomas is a beautiful tool that automatically formats your code and ensures consistency, also in indentation. But using code like with the Feliz library, there some serious drawbacks.

Testing an Event Driven Design of a Resuscitation Protocol

In a previous post a described an event driven domain design to run a resuscitation protocol. I also mentioned that running this protocol in practice can have some pitfalls. One of these pitfalls is the use of a defibrillator that is required to apply a cardio conversion by delivering a shock. We have to test that this cannot ever occur.
