Exciting New Tools for Designers, May 2022

,

The underlying theme of this month’s collection of new tools and resources is development. Almost every tool here makes dev a little easier, quicker, or plain fun. There are a few great tutorials in the mix to help you get into the spirit of trying new things and techniques.

Here’s what is new for designers this month…

Cryptofonts

Cryptofonts is a huge open-source library of icons that represent cryptocurrencies. There are more than 1,500 CSS and SVG elements in the collection. Cryptofonts includes all scalable vector icons that you can customize by size, color, shadow, or practically anything else. They work with Sketch, Photoshop, Illustrator, Adobe XD, Figma, and Invision Studio, and there’s no JavaScript.

 

Reasonable Colors

Reasonable Colors is an open-source color system for building accessible and beautiful color palettes. Colors are built using a coded chart. Each color comes in six numbered shades. The difference between their shade numbers can infer the contrast between any two shades. The differences correspond to WCAG contrast ratios to help you create an accessible palette. This is a smart project and a valuable tool if you work on projects where color contrast and accessibility are essential (which is all of them).

 

Chalk.ist

Chalk.ist is a fun tool to make your code snippets look amazing. Add your code (there’s a vast language selector), pick some colors and backgrounds, and then download it as a shareable image. Your code has never looked so beautiful!

 

WeekToDo

WeekToDo is a free minimalist weekly planner. Improve productivity by defining and managing your week and life easily and intuitively. Plus, this tool is focused on privacy with data that is stored on your computer (in your web browser or the application). The only person who has access to it is you.

 

Bio.Link

Bio.Link is a tool that collects all your links – from social media to blog posts to any other kind of link you want to share. It’s free to use, includes 15 design themes, visitor stats, and is super fast.

 

Spacers

Spacers are a set of three-dimensional space characters that you can use in projects. Characters are in multiple poses and ultra high-def formats to play with.

11ty

11ty is a super simple, static website generator. Try it for small projects and read the documentation to see everything you can do with this tool.

Scrollex

Scrollex is a react library that lets you build beautiful scroll experiences using minimal code. You can create scroll animations in all kinds of combinations – vertical, horizontal, almost anything you want to try. The documentation is fun and easy to understand if you’re going to see how it works.

GetCam

GetCam is an app that lets you turn your smartphone into a webcam for your computer. It works with any iPhone and a Mac or Windows computer. It works with most video conference and streaming tools as well as browser-based apps.

Flatfile

Flatfile is a data onboarding platform that intuitively makes sense of the jumbled data customers import and transforms it into the format you rely on. You won’t have any more messy spreadsheets or have to build a custom tool.

Loaders

Loaders is a collection of free loaders and spinners for web projects. They are built with HTML, CSS, and SVG and are available for React and copypasta.

Lexical

Lexical is an extensible JavaScript web text-editor framework emphasizing reliability, accessibility, and performance. It’s made for developers, so you can easily prototype and build features with confidence. Combined with a highly extensible architecture, Lexical allows developers to create unique text editing experiences that scale in size and functionality.

Picture Perfect Images with the Modern img Element

This tutorial is a primer on why the img element is such a powerful tool in your development box. Images are so prominent that they are part of the most important content in over 70% of pages on both mobile and desktop, according to the largest contentful paint metric. This post takes you through how to better optimize and improve core web vitals simultaneously.

Building a Combined CSS-Aspect-Ratio-Grid

Building a Combined CSS-Aspect-Ratio-Grid provides two solutions for creating the title effect. You can define an aspect ratio for the row or use Flexbox with a little flex grow magic. Learn how to try it both ways.

QIndR

QIndR is a QR code generator made for events and appointments. The form is designed to capture your event information so you can quickly build and use a QR code for listings and even allow users to add it to their calendars! It’s super quick and easy to use.

On-Scroll Text Repetition Animation

On-Scroll Text Repetition Animation shows you how to create an on-scroll animation that shows repeated fragments of a big text element. This is a fun and easy lesson that you can use right away.

Eight Colors

Eight Colors won’t do anything for your productivity, but it is a fun game that you may not be able to stop playing. It is a block-shifting game with the goal to shift circular blocks to reach the target given.

Creative Vintage

Creative Vintage is a pair of typefaces including a thin script and vintage slab serif (with rough and smooth styles). The pair is designed to work together for various uses or can be used independently.

Hardbop

Hardbop is a vintage-style typeface with a lot of personality. It would work great for display, and the family includes seven full-style character sets.

Kocha

Kocha is a funky ligature-style typeface perfect for lighter design elements, including logos or packaging. It includes clean and rough versions.

Magnify

Magnify is a large font family with 16 styles and plenty of fun alternates. You can use it straight or with the more funky styles that create less traditional character forms.

Stacker

Stacker is a fun and futuristic style font with a triple outline style. Use it for display when you really want to make an impression.

Java Records vs. Lombok

,

Java for a lot of time has been accused and mocked for its verbosity. Even the most passionate Java developers have to admit that it felt ridiculous to declare a bean class with two attributes. If you follow the right recommendations, you end up adding not only getters and setters, but also the implementations of toString hashcode and equals methods. The final result is a chunk of boilerplate that invites you to start learning another language. 

Java

  

import java.util.Objects; public class Car { private String brand; private String model; private int year; public String getBrand() { return brand; } public void setBrand(String brand) { this.brand = brand; } public String getModel() { return model; } public void setModel(String model) { this.model = model; } public int getYear() { return year; } public void setYear(int year) { this.year = year; } @Override public String toString() { return "Car{" + "brand='" + brand + ''' + ", model='" + model + ''' + ", year=" + year + '}'; } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; Car car = (Car) o; return year == car.year && Objects.equals(brand, car.brand) && Objects.equals(model, car.model); } @Override public int hashCode() { return Objects.hash(brand, model, year); }
}

How to Scale Your Design Process and Improve Handoff

,

It’s something every design team dreams about – a better design process and handoff procedure. Your design team is not alone if you are looking for a better solution.

Imagine what your workflow would look like if you could forgo the struggles of image-based technology, design and handoff with accurate components that have interactive features. Projects in the design phase will look more like final products and, most importantly, interact like final products. 

Let’s imagine a new design process together.

Challenges of an Image-Based Design Process

Here’s what we all know – image-based design tools provide pictures of components in the visual form but lack the interactivity and conditions that exist in the end-product. There’s not a high level of functional fidelity there, and it can cause confusion among design teams and rework.

These tools require you to redraw the fundamental components and design with boxes and rectangles, which takes too much time and can create a disconnect between the design and development teams. 

Further, you don’t fully maximize the potential of a design system because of inconsistencies between code-powered systems that developers use and these image-based systems for designers. There’s an innate gap between maintaining the environments and creating consistency in components. 

The final and maybe most difficult challenge with an image-based design process is in usability testing. You just can’t test an image the way you can working components. If the prototype is not interactive enough, you lose valuable feedback in the testing process. Functional fidelity is a must-have design and development tool in 2022. 

Iress, market-leading financial software, had many of these same problems in its design system process. You can probably relate to its story, which includes a designer and engineer who aren’t entirely on the same page, hit the deadline and have to deliver, and then get customer feedback. The result was a lot of extra headaches and work. 

But there is a better way: Import all user interface components into a code-powered design system in sync with a design tool so that your team can work in harmony to build, scale, and handoff projects with ease. 

Scale Design With Accurate Components

Here’s what most design and development teams want en route to building products: Accurate components with built-in interactivity, states, and conditions. No redrawing boxes and rectangles; no trying to figure out what states and interaction should be.

And if you can do it with ten times the speed and agility? Now you’re really in business. 

“It used to take us two to three months just to do the design. Now, with UXPin Merge, teams can design, test, and deliver products in the same timeframe,” said Erica Rider, Senior Manager for UX at PayPal. “Faster time to market is one of the most significant changes we’ve experienced using Merge.”

The time and workflow savings come from the ability to maintain only one environment as a product team. Rather than image-based tools, a code-powered design system that will push updates to components as the design evolves is the modern way to work. This workflow can also eliminate duplicate documentation so that your team has a single source of truth for whole product teams. 

Now you can be more agile in the design process and scale. And as Rider hinted at, there is a solution already available in UXPin Merge. 

Scalability with accurate design components has other benefits as well. 

Teams can onboard people faster because the design system is in the design tool. There’s less searching for answers with drag and drop-ready building blocks. New team members will find more success and be more valuable to the team quicker due to fewer inconsistencies and errors. 

Testing also gets a boost as you scale with a single source of truth. You can actually create better usability tests with a high-fidelity, functional version of the prototype, allowing users to leave more valuable and detailed feedback that can improve your product in the early stages. 

Better Handoffs Start Here

As you imagine a better design process, take it one step further. Better handoffs are a goal for most teams. 

An interactive component-based design tool can eliminate the need for multiple iterations of the same meeting to explain how a prototype works. Everyone can see and interact with it for themselves with accurate, true components that ensure the prototype works the same as the product. 

Designers will feel more like their vision is making it into the final product, and developers have a better idea of how to work. Everyone has the exact same components written in code. Thanks to the single source of truth, devs can speed up as they build the product because they start with components that include production-ready code.

A typical design to developer handoff might have multiple steps: Create vector design elements, create a model for interactions, and then send the prototype with documentation. Not to mention the meetings that are required to make sure everyone is on the same page.

In a model with interactive component elements, the developer handoff is fast and easy; they create a prototype with true components and all the built-in properties. The developer copies the JSX code and pastes it into his tool to build the final product. All the component properties and their coded interactions already exist in the source code. This is possible because the source of truth is the code itself, the source code.

Quick Tool Solution and Technical Use

This solution to this common challenge is not somewhere in the future; it’s already here.

UXPin, a code-based design tool, has Merge technology, which allows you to bring all interactive components into UXPin. Then you can use your own, or the open-source library with the ready-made building blocks to get products ready faster.

Here are just a few of the things you can do with Merge by UXPin:

  • Integrate your developer’s storybook to use it as a single source of truth (works for all frameworks)
  • Import design system components from a dev’s Git repository, such as GitHub, Bitbucket, GitLab, or others (works with React)
  • Work with the built-in MUI library
  • Add the npm component package to UXPin on your own (no developer required)
  • Design with the confidence that your work can be ideally reflected by developers
  • Create and share a library of interactive components

Summary 

Say bye-bye to redrawing rectangles – build more accurate prototypes easier and end-products faster with Merge by UXPin.

Now is the time to solve one of your biggest design challenges while upgrading and scaling the design process and improving handoffs. 

Merge by UXPin is user-friendly and made for scalable projects of almost any size. The line between design and development blurs with quicker product release and a fully-interactive solution. Request access today.

A Beginner’s Guide to High-Performance Computing in Python

,
Ever since the Python programming language was born, its core philosophy has always been to maximize the readability and simplicity of code. In fact, the reach for readability and simplicity is so deep within Python’s root that, if you type import this in a Python console, it will recite a little poem:

    Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. The complex is better than complicated. The flat is better than nested. Sparse is better than dense. Readability counts…

Simple is better than complex. Readability counts. No doubt, Python has indeed been quite successful at achieving these goals: it is by far the most friendly language to learn, and an average Python program is often 5 to 10 times shorter than equivalent C++ code. Unfortunately, there is a catch: Python’s simplicity comes at the cost of reduced performance. In fact, it is almost never surprising for a Python program to be 10 to 100 times slower than its C++ counterpart. It thus appears that there is a perpetual trade-off between speed and simplicity, and no programming language shall ever possess both.
But, don’t you worry, all hope is not lost.

Taichi: Best of Both Worlds

The Taichi Programming Language is an attempt to extend the Python programming language with constructs that enable general-purpose, high-performance computing. It is seamlessly embedded in Python, yet can summon every ounce of computing power in a machine — the multi-core CPU, and more importantly, the GPU.
We’ll show an example program written using taichi. The program uses the GPU to run a real-time physical simulation of a piece of cloth falling onto a sphere and simultaneously renders the result.
Writing a real-time GPU physics simulator is rarely an easy task, but the Taichi source code behind this program is surprisingly simple. The remainder of this article will walk you through the entire implementation, so you can get a taste of the functionalities that taichi provides, and just how powerful and friendly they are.
Before we begin, take a guess of how many lines of code this program consists of. You will find the answer at the end of the article.

Algorithmic Overview

Our program will model the piece of cloth as a mass-spring system. More specifically, we will represent the piece of cloth as an N by N grid of point-masses, where adjacent points are linked by springs. The following image, provided by Matthew Fisher, illustrates this structure:
The motion of this mass-spring system is affected by 4 factors:
  • Gravity
  • Internal forces of the springs
  • Damping
  • Collision with the red ball in the middle
For the simplicity of this blog, we ignore the self-collisions of the cloth. Our program begins at the time t = 0. Then, at each step of the simulation, it advances time by a small constant dt. The program estimates what happens to the system in this small period of time by evaluating the effect of each of the 4 factors above, and updates the position and velocity of each mass point at the end of the timestep. The updated positions of mass points are then used to update the image rendered on the screen.

Getting Started

Although Taichi is a programming language in its own right, it exists in the form of a Python package and can be installed by simply running pip install taichi.
To start using Taichi in a python program, import it under the alias ti:
import taichi as ti
The performance of a Taichi program is maximized if your machine has a CUDA-enabled Nvidia GPU. If this is the case, add the following line of code after the import: ti.init(arch=ti.cuda)

If you don’t have a CUDA GPU, Taichi can still interact with your GPU via other graphics APIs, such as ti.metal, ti.vulkan, and ti.opengl. However, Taichi’s support for these APIs is not as complete as its CUDA support, so, for now, use the CPU backend: ti.init(arch=ti.cpu)And don’t worry, Taichi is blazing fast even if it only runs on the CPU. Having initialized Taichi, we can start declaring the data structures used to describe the mass-spring cloth. We add the following lines of code:

Python

  

 N = 128 x = ti.Vector.field(3, float, (N, N)) v = ti.Vector.field(3, float, (N, N))
