Matplotlib: Change Scatter Plot Marker Size

Introduction Matplotlib is one of the most widely used data visualization libraries in Python. Much of Matplotlib's popularity comes from its customization options - you can tweak just about any element from its hierarchy of objects. In this tutorial, we'll take a look at how to change the marker size in a Matplotlib scatter plot. Import Data We'll use the World Happiness dataset, and compare the Happiness Score against varying features to see what influences perceived happiness in the world: import pandas as pd df = pd.read_csv('worldHappiness2019.csv') Then, we can easily manipulate the size of the markers used to represent entries in this dataset. Change Marker Size in Matplotlib Scatter Plot Let's start off by plotting the generosity score against the GDP per capita: import ma...

Rollback Transaction With Laravel Eloquent

Rolling back queries is always a safeguard for your data if there were to be any errors during database manipulation. For example, during the execution of multiple delete commands or similarly, a save command in use with an update use-case. Laravel comes out-of-the-box with the rollback functionality and is particularly very simple to use. The answer to rolling back eloquent queries is to use a static DB::transaction call, wrapped around your database execution code. This addition to your standard controller code looks like the following ‘wrapper function’. DB::transaction(function () use ($product) { // Start the transaction // Do stuff here }); // End transaction You can pass in variables using the use operator so you don’t have to wrap all of your code inside of the transaction...

Creating UI Components in SVG

I’m thoroughly convinced that SVG unlocks a whole entire world of building interfaces on the web. It might seem daunting to learn SVG at first, but you have a spec that was designed to create shapes and yet, still has elements, like text, links, and aria labels available to you. You can accomplish some of the same effects in CSS, but it’s a little more particular to get positioning just right, especially across viewports and for responsive development. What’s special about SVG is that all the positioning is based on a coordinate system, a little like the game Battleship. That means deciding where everything goes and how it’s drawn, as well as how it’s relative to each other, can be really straightforward to reason about. CSS positioning is for layout, which is great because you have thin...

How to Load Fonts in a Way That Fights FOUT and Makes Lighthouse Happy

A web font workflow is simple, right? Choose a few nice-looking web-ready fonts, get the HTML or CSS code snippet, plop it in the project, and check if they display properly. People do this with Google Fonts a zillion times a day, dropping its <link> tag into the <head>. Let’s see what Lighthouse has to say about this workflow. Stylesheets in the <head> have been flagged by Lighthouse as render-blocking resources and they add a one-second delay to render? Not great.We’ve done everything by the book, documentation, and HTML standards, so why is Lighthouse telling us everything is wrong? Let’s talk about eliminating font stylesheets as a render-blocking resource, and walk through an optimal setup that not only makes Lighthouse happy, but also overcomes the dreaded flash o...

Spectre.Console lets you make beautiful console apps with .NET Core

I've long said, as a fan of the console and text mode, that the command line is underloved. You can do accelerated 3D VR, sure, but impress me with a nice ASCII progress bar or spinner and oh my! *Chef's kiss* Enter yet another lovely Console library in the form of Spectre.Console. You may know Patrik Svensson as the creator of the wonderful Cake build system. He is also enhancing our consoles with Spectre.Console. It even has support for Figlet! What's FIGlet you say?!? Well, it's giant fonts with ASCII, of course! _____ ___ ____ _ _ | ___|_ _/ ___| | ___| |_ | |_ | | | _| |/ _ __|| _| | | |_| | | __/ |_ |_| |_______|_|___|__| Not very accessible, to be sure, but super impactful for the sighted.

How to make a WinForms app with .NET 5 entirely from the command line and publish as one self-contained file

I got a lovely email from a reader named Steven who has been doing .NET for many years and is excited about .NET 5. He has an interesting perspective: I really like the .NET library. During 2020, I've taught myself enough Windows Forms to write my own JPG photo viewer.  Sorry but I'm not a fan of XAML, so I just write and compile raw Windows forms in C#. Now before we start, I would offer that XAML is how you express your UI in WPF, and there is a WinForms designer for .NET Core in the latest version of Visual Studio so if you do want to mix and match using a designer and also writing your WinForms straight you can do that these days. Steven asks: I wonder if you could help me with a good recipe for command line compile on C#9 / .NET 5 to make a .exe? More specifically he adds: I want...
Detect Generator Functions with JavaScript

Detect Generator Functions with JavaScript

In the current JavaScript climate of new syntaxes, features, and using loads of external libraries, it seems harder than ever to be sure what your functions are being given or even what the data represents. Of course, we've come up with Flow and TypeScript to help, but we can't count on those always being available. That's why I like doing my own detection with JavaScript, especially when it comes to function types. To detect if a function is a generator or async generator function, you can use the following code: // Sample generator function function* sampleGenerator() {} sampleGenerator.constructor.name // "GeneratorFunction" async function* sampleGenerator() {} sampleGenerator.constructor.name // "AsyncGeneratorFunction" Coincidentally, you can also detect a regular async f...
