TOPTOP.RU is an online women's clothing store that combines different styles and trends, and focuses on providing quality service to its customers. They value marketing and product expertise, as well as understanding their audience’s interests and expectations. Therefore, many tasks that are usually outsourced are completed in-house, including product photography, design, work with analytics and promotion, and individual digital services for each client.

In 2019, the TOPTOP.RU team prepared new layouts for their website, which was a slow, monolithic RoR application. The revamp was designed to help customers find products faster and let them work more conveniently with the catalog.

The development team needed to preserve the existing functions and some of the old pages, while making a frontend based on the new layouts. We had experience both supporting and launching products in Ruby on Rails, and we were ready to [get involved and treat the product as if it were our own.](https://evrone.com/toptop)
Life lessons learned while 
                coding
Published: 2021-02-19 11:50:06

Coding is not always the nerd's game sometimes it teaches you many essential life lessons. You just need to be optimistic enough to observe better side of literally everything.

```Few lessons I learned while coding are :```

**Persistence**
I have been doing proper coding for 2.5 months now, these days I have a constant realization that persistence has becomes such a part of my life now. I have never been this focused, hardworking through-out my entire life. This phase of life feels special. 
Though I strictly believe you should not code to learn "How to be persistent at tasks", Instead the act of coding will call for persistence.

**Creative Thinking**
Programming is not boring like most of the other computers related
stuffs like maintaining data sheets, using excel in general. Coding is a good creative space to be in. And therefore it add those values in life too.
Coding improves the functions of both the hemisphere and in turn develops the brain as a whole. We know that coding exercises logical and analytic thinking, but it is less know that it also exercises imaginations and intuitive thinking.
To get a broader perspective with more facts read:

There are many more points like Open-mindedness, The Art of Making
but I don't think I am capable and experienced enough to write about those now may be in a sooner future till then See ya!!

Tips to save time typing document.getElementById() and document.createElement() in javascript
Tags: javascript
Published: 2021-02-19 11:43:46


You can save time typing document.getElementById(elementId) and document.createElement(elementType) by following a simple trick:

- Create a function which executes either of the above lines of code
- Assign the function to a variable
- Use that variable instead of typing the redundant code

Here is a demo with screenshots:

A previous blog post described the Java Gotcha "Bitwise vs Boolean Operator".

- [Java Gotchas - Bitwise vs Boolean Operator](https://dev.to/securecodewarrior/java-gotchas-bitwise-vs-boolean-operators-11km)

We added a variant of this, and some other Java Gotchas into a fun little Quiz called "[Challenge The Sensei](scw.typeform.com/to/rgw7q7OE)".

- [scw.typeform.com/to/rgw7q7OE](https://scw.typeform.com/to/rgw7q7OE)

If you've read the blog post above then you'll be in a good place to ace at least one of the questions.

_But your friends might not, so if you find the quiz fun, you can share it with them and see if they score as well as you._

Since we don't want to just quiz you. We want to try and use this to help educate and codify the knowledge. So we have created a Github repo that has runnable code examples for the problem, and the solution.

- [github.com/SecureCodeWarrior/challenge-the-sensei](https://github.com/SecureCodeWarrior/challenge-the-sensei)

This is a [Sensei](https://plugins.jetbrains.com/plugin/14015-sensei-by-secure-code-warrior-) enabled repo.

When you clone the repo and load it into IntelliJ, assuming you have the Secure Code Warrior [Sensei](https://plugins.jetbrains.com/plugin/14015-sensei-by-secure-code-warrior-) IntelliJ Plugin installed, then it will automatically see that you have a `.sensei` folder, and load the Sensei recipes.

When browsing the code in the IDE you should see IntelliJ prompt you that the error exists in the code, and this should make it easier to see the gotcha in the code:

- Hover over the highlighted code then you'll see a prompt telling you about the error
- Use the `Show Context Action` key: `alt+enter` (Windows) `option+enter` (macOS) and we may have a QuickFix available that can fix the code.

Sensei recipes have been added for:

- [Bitwise operators](https://github.com/SecureCodeWarrior/challenge-the-sensei/blob/master/src/main/java/com/securecodewarrior/bitwiseoperators)
- [Split IP Address](https://github.com/SecureCodeWarrior/challenge-the-sensei/blob/master/src/main/java/com/securecodewarrior/splitipaddress)
- [Assert Order](https://github.com/SecureCodeWarrior/challenge-the-sensei/blob/master/src/test/java/com/securecodewarrior/assertorder)

We are adding more recipes and more explanatory text to cover the rest of the code in the future... but don't let that stop you from having a look at the code and spotting the error yourself.

And remember to try the quiz and "[Challenge the Sensei](https://scw.typeform.com/to/rgw7q7OE)"

Design systems and tokens
Tags: ux, productivity, webdev, design
Published: 2021-02-19 11:40:28

## What is a design system?

A design system is a collection of reusable components, guided by clear standards, that can be assembled together to build any number of applications.

![Image](https://www.webdesignerdepot.com/cdn-origin/uploads/2019/06/Mailchimp-1.jpg)

![Image](https://miro.medium.com/max/1600/1*UPtMMr8C5HRNQHjMHlizSg.gif)



## What’s the difference between a design system and a style guide or pattern library? 

A design system isn’t only a collection of the assets and components you use to build a digital product. According to Emmet Connolly, director of product design at Intercom, “… most Design Systems are really just Pattern Libraries: a big box of UI Lego pieces that can be assembled in near-infinite ways. All the pieces may be consistent, but that doesn’t mean the assembled results will be. Your product is more than just a pile of reusable UI elements. It has structure and meaning. It’s not a generic web page, it’s the embodiment of a system of concepts.”

## What is a design tokens?

![Image](https://s3.amazonaws.com/www-inside-design/uploads/2019/11/InVision_Cover.png)

Design tokens allow product teams to better collaborate and ensure brand consistency across any platform.

Design Tokens are used in place of hard-coded values and variables in order to ensure flexibility and unity across all product experiences and/or platforms. They are also platform-agnostic so it makes it easier to communicate with developers using these terms.

With design tokens, you can capture low-level values and then use them to create the styles for your product or app. You can maintain a scalable and consistent visual system for UI development.

10 Tips to quickly improve your UI designs
Tags: ux, design
Published: 2021-02-19 10:58:53

1. You should know your users
Above all else, you have to know who your users are—inside and out. Don't stop at knowing what your users want. Dig deeper and find out what they need.

2. Define how people use your interface
Before you design your interface, you need to define how people will use it. 

3. Set expectations
Make sure users have an idea of what will happen before they do it, for example, what will happen after clicking a certain button.

4. Predict mistakes
People make mistakes, but they shouldn’t always have to suffer the consequences. There are two ways to help lessen the impact of human error:

            -Prevent mistakes before they happen
            -Provide ways to fix them after they happen

5. Give feedback—fast
Just make sure your things work quick or in others, word respond quickly

6. Think carefully about element placement and size
This is a crucial thing in design, you must choose what shows users clearly like if it's the menu button, it should well aligned and seenable.

7. Don’t ignore standards
Being highly creative types, designers tend to love to reinvent things—but it’s not always the best idea. You must follow the standards of design.

8. Make your interfaces easy to learn
Simplicity in design is the best practice, so you have to make your design easy to understand.

9. Make decision-making simple

10. Listen to the data

How to build an Echo Chatbot in Python
Tags: python, codenewbie, beginners, tutorial
Published: 2021-02-19 10:40:40

Hello everyone! Long time, no see... Well, today we are going to create a simple **Echo Chatbot in Python**.

## How does it work?

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bupvet0av2efixqgz87u.png)

An Echo Chatbot is basically a program which can repeat the phrases of the user. 

And it keeps running until a specific phrase is received from the user.

Super quick and fun project! Let's get into coding.

## Let's Code

First, let's print a greeting message and also instruct the user on how to end the conversation.

```python
print("Let's talk! Enter 'quit' to exit...")
```

The conversation will continue until the user has a specific input which in our case is **`quit`**.

Let's create a **`while`** loop to keep the program executing.

```python
while True:
	pass
```

Alright, so the first thing we are going to do is to ask the user to input some text and start the conversation.

```python
while True:
	user = input("You: ")
```

Now it's our bot's turn to reply to the user. Since it's a simple echo chatbot, it will repeat what the user has said.

```python
while True:
	user = input("You: ")
	print(f"Bot: {user}")
```

This can simply be achieved through using an **`print()`** statement and printing variable within it. We are using **`f-string`** method which is a new way of printing variables within **`print()`** statement in **Python 3**.

Now for one last step, if the user passed the input of **`quit`** keyword then out program should stop running. 

Let's use an **`if`** conditional to **`break`** the loop if **`quit`** is found in the user input.

```python
while True:
	user = input("You: ")
	print(f"Bot: {user}")
	if user == 'quit':
		  break
```

Here we did it! Awesome 🤩
