Recently I have been doing some web scraping in Kotlin, and have now got a regularly updated set of records appearing in my database. An interesting challenge arose when the scraped data was not quite as nice to work with as the web view I was scraping from. With a little front end whizz-bangery, the … Read more
Whenever I pick up a new programming language, sooner or later I get comfortable enough with it to want to tackle my favourite / most common personal programming need: web scraping. Recently I have been playing with Kotlin quite a lot, and am now at the point where I have written a few simple web … Read more
As part of my post on Kotlin Task Scheduling I had a piece of code that used Kotlin’s timerTask function that I wanted to dive deeper into, but that wasn’t the best place to do so. So, this post is going to cover that off. Here’s the code for reference: And to quickly recap at … Read more
Out of nothing other than sheer curiosity, I was wondering how Kotlin (and by extension, Java) handles scheduling tasks. Let’s say that we have a function that we wish to run every 5 seconds. How can we go about achieving that in Kotlin? That was the question I set out to answer. In this post … Read more
I got really lucky with the fix for this one, as it had me scratching my head for a good while. The gist of this is that I had two classes – a base class, and a sub class. I wanted to call a method with the same name on the sub class as exists … Read more
OK, not a true fix today. Not in the sense that I’d like, anyway. The gist of this is that I was trying to follow along with the JetBrains official Introduction to Coroutines and Channels tutorial. I cloned the GitHub repo, and opened in IntelliJ. When the dependencies were downloaded via Gradle, I got the … Read more
All week now I’ve been wanting to have a try with JetBrain’s Compose Multiplatform Desktop. The demos I’ve found looked great. As a heads up though, those demos are all showing OSX as the run target. I am aware that Compose for Desktop can run against Windows, and (interesting to me) Linux. What I was … Read more
In this post I will cover a way to convert only JSON keys from snake_case format to camelCase format, without impacting the values. I hit on this problem today, and found multiple solutions that rely on code to solve this problem. I didn’t need a code solution, as my use case was something of a … Read more
A very specific issue today, but one that I found quite a nice solution for – albeit with the need to install some extra things. The issue I faced was that I have a large number of directories, each containing 10-15 images. For each directory I needed the file name, and image dimensions for every … Read more
Here’s the problem we are addressing today: you have a set of numerical data returned by your Postgres query. Your numbers look alright, but some very high (or very low) values seem to be throwing things out of whack. What you’d like to do is eliminate the outlying values from your result set, and keep … Read more
