Exciting New Tools for Designers, September 2020

,

It’s fun to see new website design tools that reflect current times and the state of the world. That’s very true this month with new databases devoted to diversity and women in technology, as well and resources to make your design life easier.

Here’s what’s new for designers and developers this month:

Ztext.js

Ztext.js is an easy to implement, three-dimensional typography tool for the web that works with any font you want to use. With the popularity of 3D effects and animation, this tool has a lot of practical applications. Everything you need, including documentation, is available from developer Bennett Feely on his website and GitHub. (It’s free but you can show appreciation with a donation if you like it.)

Gradient Magic

Gradient Magic is a free gallery of fun and interesting CSS gradients. You can sort through a random selection or by category of color to find just the right gradient for your project. Some of them would make really neat backgrounds or image overlays.

Impossible Checkbox

Impossible Checkbox is a fun little divot that you’ll want to play with and emulate. Click or tap the slider to activate and a nifty little friend pops up. Now here’s the fun part: You can’t leave it checked, and take note of the changing expression of the checkbox character.

Diversify Tech

Diversify Tech isn’t your average job board; it is a collection of resources – and opportunities – for underrepresented people in technology. It includes a weekly roundup and everything from scholarships, to events, to jobs, to speaking opportunities.

Women in Tech

Women in Tech is a list of apps made by women. The apps are ranked and chosen based on upvotes and is a good resource if you want to help support women-owned projects. Search or submit an app for inclusion.

Devello Studio

Devello Studio is a tool that allows you to write code in the cloud. You don’t have to install anything and no matter where you are, just can open a project in-browser, and continue development where you had left off last time. Plus, it works with GitHub support built right in.

Hustl

Hustl is a premium Mac app that allows you to create time-lapse videos of your screen. Use it to show off work or projects or create a cool video for your portfolio. Plus you can use it to capture just one active app so you don’t have to do a lot of editing later.

FeedBaxley

FeedBaxley is a user feedback tool that helps you (and users) figure out what’s frustrating before it becomes a real issue. You can customize everything to match your brand and set it up with copy and paste tools. Feedback integrates with Slack, making it easy for you to analyze information with a team.

BestTime

BestTime launched a major update with a new tool that makes it possible to analyze visitor peaks of public business (cafe, gym, etc) for whole areas. Using the heatmap API you can find businesses at popular times, locations, or by business type.

Pixeltrue

Pixeltrue is a new collection of free SVG illustrations and Lottie animations in a trendy style. They are available for commercial and personal use and add a bit of whimsical delight to website projects. (The error illustrations are particularly fun.)

Previewed

Previewed has tons of cool and realistic mockups that you can use to create the perfect setting for digital projects. You can find mockups for a variety of devices and cool panoramas that work perfectly for elements such as app store previews.

Alt Text Overlay Bookmarklet

The Alt Text Overlay Bookmarklet solves a common problem: It shows what images use alt text and what that text is. The tool was created by Christian Heilmann and he’s put it on GitHub for you to play with and test.

MergeURL

MergeURL allows you to merge and shorten up to five links. Enter the links and mergeurl.com/o/xxxxx, for example, will open all the URLs associated with that link. The tool is free to use and you don’t have to register to use the service.

Infinity Search

Infinity Search is a new search engine that lets you look for things privately and efficiently. Search the web, images, or videos. Here’s a little about how it works: “While we retrieve results from other search engines like Bing and Wikipedia, we also have our own indexes of links that are displayed in our search results. We are actively working on improving these indexes and they will only get better.”

Blade UI Kit

Blade UI Kit is a set of renderless components to use in Laravel Blade Views. It’s built for the tall stack and is completely open source. It includes 26 components and you can contribute as well.

Trusted News

Trusted News is a Google Chrome extension that uses AI to assist in evaluating the quality of the online content. In its first release, it scores the objectivity for a selected article, testing whether it is written from a neutral perspective as opposed to a subjective one.

It works with all major databases including MySQL, PostgreSQL, Amazon Redshirt, Microsoft SQL Server, and more.

Introduction to PDO Extension: How to Use PDO for Different Databases

,
In this article, we will talk about what a PDO is, why is it necessary, and how to work with it.
Let’s start with the fact that for a long time php-programmers have been discussing the fate of the native functions to work with the database: mysql_connect, mysql_query, and others. The fact is that in upcoming versions of PHP data will be erased, these functions will go "Obsolete". Thus PHP developers should force on other tools to work with the database.
Currently, there are two alternatives solutions; mysqli extension and expansion of PDO. In this article, we will discuss PDO.
PDO – PHP Data Objects – is a layer that offers a versatile way to work with multiple databases.
This layer has several advantages:
  • PDO allows you to work with different databases, such as: MYSQL, Oracle, PostgreSQL and many others.
  • PDO allows you to work with a prepared statement
Now let’s talk about all this in more detail.

Connecting to a Database Using PDO

Before you start working with PDO, you must make sure that you have the correct extension – php_pdo_mysql.dll. This can be verified through the function phpinfo(). If everything is okay, you are good to go.
First we need to connect to the database:
PHP

  

xxxxxxxxxx
1

15

 

1 

/ / MuSQL

2 









 3 




   $Database = new PDO ("mysql: host = $ host; dbname = $Databasename", $username, $password); 








 4 












 5 




/ / PostgreSQL








 6 












 7 




   $Database = new PDO ("pgsql: host = $ host; dbname = $Databasename", $username, $password);








 8 












 9 




/ / MS SQL








 10 












 11 




   $Database = new PDO ("mssql: host = $ host; dbname = $Databasename", $username, $password); 








 12 












 13 




/ / SQLite








 14 












 15 




   $Database = new PDO ("sqlite: my / database / path / database.db");














 




 
















 As you can see from the example, each database connection string is slightly different from each other



 You should always use try/catch when you are trying to connect to the unit, so that on exception we do not disclosed any data to the user.









 PHP 


   






  




 






 




 


 














xxxxxxxxxx




 1 






 


 




   










 1 




try {








 2 




   $Database = new PDO ("mysql: host = $ host; dbname = $Databasename", $username, $password); 








 3 




} 








 4 




catch (PDOException $ e) { 








 5 




   echo "Unable to connect to database"; 








 6 




}

	5 Best Free Courses and Resources to Level Up As a Web Designer				
,  


 I often see freelancers on social media asking what the secret is to working fewer hours, making more money, and helping new clients to find them. While those things tend to happen the longer you’ve been freelancing, it doesn’t happen without some effort.


If you’re wondering how you can change things so that your business becomes more profitable and easier to manage, education is the key.


But it’s not just mastering new design techniques that will take you to the next level. It’s important to invest your time in a well-rounded education so that you can grow not just as a web designer, but also as a freelancer and business owner.


The good news is that you don’t have to spend a ton of cash on courses or resources. In the following round-up, I’m going to share some of the best free courses to help you level up.


5 Best Free Courses and Resources for Web Designers


Rather than sign up for Udemy, Skillshare and other premium course membership sites, I recommend taking a bootstrapping approach to self-education. I mean, the whole point in learning new skills and strengthening existing ones is so you can run a better business and make more money, right?


Once you have extra funds to throw at premium courses, definitely explore those options. For now, let’s focus on the free courses and resources that’ll help get you to that next level:


1. edX




edX was created by Harvard and MIT in order to provide university-level training and education to anyone, anywhere. While you can’t get certified without paying a few hundred dollars, you can go through entire courses for free.


Courses are offered over a wide range of categories. As a freelance web designer, you’d do well to focus on the following areas:


Design

Learn more than just how to design beautiful interfaces. Learn about the technical side of it, too — things like AI, IoT, and cybersecurity.


Computer Science

Learn web development and coding.


Business & Management

Learn essential business skills like:


    

  • Project management
    • 

  • Finance management
    • 

  • Leadership
    • 

  • Marketing and analysis
    • 



Communication

Learn things like branding, negotiation, reputation management, and critical thinking.


2. Envato Tuts+




Envato Tuts+ might be best known for its succinct step-by-step design and development tutorials. However, it has a new section of free video courses to take advantage of.


Although you won’t learn any soft skills here, this is a great resource if you want to master the tools of your trade.


Free courses give you a deeper look at tools like:


    

  • HTML, CSS, and JavaScript
    • 

  • Adobe’s suite of software
    • 

  • Sketch
    • 

  • WordPress
    • 

  • Video conferencing tools
    • 



3. YouTube


YouTube is more than just a place to watch entertaining videos. There are some amazing YouTube channels for web designers at all skill levels.


When choosing a design channel and course to follow, look for ones that are well organized. If they’re just posting videos at random without any rhyme or reason, it’ll be difficult to focus on and master one skill set before moving onto the next.


Here are the channels I recommend you follow:


Flux




Learn skills related to:


    

  • Web design
    • 

  • Getting started as a freelancer
    • 

  • Strengthening your processes
    • 

  • Building your portfolio
    • 

  • Design theory and strategy
    • 



CharliMarieTV




Learn skills related to:


    

  • Web design
    • 

  • Building sites with Figma or Webflow
    • 

  • Career paths for designers
    • 

  • Productivity hacks
    • 



NNgroup


Learn skills related to UX:


    

  • Web design
    • 

  • User psychology
    • 

  • Usability testing
    • 

  • Design thinking
    • 

  • Research and data analysis
    • 

  • Journey mapping
    • 

  • Get access to UX Conference seminars, too
    • 



4. Moz Whiteboard Fridays




Even if you don’t offer SEO as a standalone service, it’s important for web designers to understand the role they play in SEO and to stay abreast of the latest and greatest strategies.


If you haven’t tuned in for one of Moz’s Whiteboard Fridays yet, I’d recommend you start now.


Some of the topics might not be relevant to you (like creating a content strategy). However, there are others you’ll get some great tips from, like the one above that talks about creating great visuals, preparing web pages with tags and schema markup, and optimizing for featured snippets.


5. Nir Eyal – Indistractible




Nir Eyal has made a name for himself over the years as an author and presenter on the subject of human psychology and behavior. His first book (Hooked) examined consumer behavior and how to design around it. His second (Indistractible) turned the focus on us — the doers and creators who build experiences and products for consumers.


The first of his free resources to explore is this 30-minute presentation on why we’re so easily distracted and how to keep those distractions (and ourselves) from getting in the way.


The second free resource to snag up is the 80-page workbook available on the homepage. Here’s a preview of what it looks like:




You’ll learn about common distractions, identify those that are specific to you, and then work through exercises to defeat them.


If this is something you’re struggling with, these resources will empower you to make a much-needed change.


BONUS: WebDesigner Depot


Although WebDesigner Depot doesn’t offer video courses, I consider each of the articles contained within this site to be mini-courses of their own. And you’ll learn everything you’ve ever wanted to know about becoming a web designer and growing your freelance business.
