A collection of useful features encountered when working with Svelte and Svelte-Kit — 1. Delaying Components Until Dom Has Loaded We often want to load our page before concentrating on resource-heavy items such as videos. Here we use a promise to check the page is ready, before loading those components. let domReady = (function () { return new Promise( function(resolve) { document.addEventListener('readystatechange', function()…

How to automatically update the .gitmodules file using Python. Convention Conventionally if we want to add a nested GitHub module, we use the snippet git submodule add <module url> <directory> Multiple Nested Repositories However, if we have several submodules we have forgotten to initialise, we have two options — add them manually or automate…

Using Python to generate statistically similar dummy datasets for use in code development and testing robustness — Whence The problem of generating a realistic dataset for testing is a prominent one. This is often encountered in one of two fields: Machine Learning or Software Engineering. Creating More Reliable Models In Machine Learning, overfitting is often a very salient problem. Should a model overfit a small/limited/imbalanced dataset, its reliability in producing accurate predictions…

Using Python to create image collections for different screen resolutions. — When designing responsive websites, we often want to reduce the loading time for our clients. One simple way to do this is to only send the information they require. …

How to translate a set of prose, and/or XML pages using a number of language-translation APIs. — Often we are faced with a problem where either we cannot understand a piece of the critical text, or we need to provide information to speakers of another language. …

Adding status notifications alerts and voice dictation from a running script — When coding, it is common that we might want to provide the user with updates on progress or script termination. This is particularly true for programs that run in the background and may have been forgotten about in the interim. I n this article, we discuss three methods for providing…

Using location or zoom levels to determine which tiles to use, and calculating their coordinates programmatically. — In visualising geographical information, data is often split into segments — chunks spanning the entire earth and decreasing based on zoom level. This means as a user, we can load only the information we are interested in. The problem however comes in wanting to extract data from a tileset without…

Finding out which datasets contain polygons within a predefined area — Background Geographical area datasets often contain a large number of polygons within each file. Additionally, the different classifications mean that there are several types of area files to choose from. If we want to locate all relevant datasets to a specific selection, it is inefficient to load each individual GeoJSON or…

Often we are interested in finding all neighbouring areas within a geographical map, and their relative overlap with an area. This article discusses how to do just that! — The dataset We begin with a toy county dataset extracted from: http://geoportal1-ons.opendata.arcgis.com/datasets/687f346f5023410ba86615655ff33ca9_1.geojson. This contains 174 areas which is sufficient to demonstrate the methods involved, but not so large it takes a long time to compute.
