Somehow I saw code in the project of a neighboring team that generated a string with URL parameters for subsequent insertion into the iframesrc attribute.
This article may seem superfluous, obvious or too simple, but since this occurs in wildlife, you should not be silent about it, but rather share best-practices.

My name is Serhii Pimenov. I’m a web developer from Kyiv, Ukraine (maybe you know me by the nickname olton).
Today I'm going to speak about one of my tools for the Mina blockchain - “Mina Monitor”. It’s the first article in the series about Mina and Mina Tools. In this article, I will introduce you to my tool for monitoring the Mina nodes.
With the help of the ESLint and Prettier features, you can automate the formatting of your code, make it more expressive and accurate, correspond to specific rules, and avoid errors and bottlenecks even before uploading the code to the shared source storage...

In the first part of You don't know Redis, I built an app using Redis as a primary database. For most people, it might sound unusual simply because the key-value data structure seems suboptimal for handling complex data models.
In practice, the choice of a database often depends on the application’s data-access patterns as well as the current and possible future requirements.
Redis was a perfect database for a Q&A board. I described how I took advantage of sorted sets and hashes data types to build features efficiently with less code.
Now I need to extend the Q&A board with registration/login functionality.
I will use Redis again. There are two reasons for that.
Firstly, I want to avoid the extra complexity that comes with adding yet another database.
Secondly, based on the requirements that I have, Redis is suitable for the task.
Important to note, that user registration and login is not always about only email and password handling. Users may have a lot of relations with other data which can grow complex over time.
Despite Redis being suitable for my task, it may not be a good choice for other projects.
Always define what data structure you need now and may need in the future to pick the right database.

As a side hustle, I teach tech recruiters web and software development technologies using plain English. It helps them with understanding job specs and resumes and it makes all of us, tech people, happier.
I run a weekly newsletter and often get feedback from recruiters via email or LinkedIn DMs.
I thought that I could try to collect feedback using the “Reactions” feature just like LinkedIn or Facebook does. It’s not as informative as personalised messages but is a simple feature that may incentivize more people to provide some general feedback.
Either way, it’s worth trying and as a software developer, I can’t wait to implement it.
This tutorial is about implementing a feature that will be used in real life on my project.

The "Click to Call" button on the website is an "innovation" that has been around for about 10 years. The technologies under the hood have changed, but the principle remains the same: someone clicks on the button on the site page, then JavaScript launches and requests access to the microphone and establishes a connection to the server — WebRTC SIP gateway. Further, the first client-server leg is a browser gateway, the second leg can be arbitrarily long and through the SIP proxy chain can eventually connect to a mobile or landline phone. Thus, the browser turns, in a sense, into a softphone and becomes a full participant in VoIP telephony.

As you know, YouTube doesn't have a feature for capturing an RTSP stream, but we would like to change this and help YouTube to make their viewers happy.

Hello, I'm Jin, and I… want to play a game with you. Its rules are very simple, but breaking them… will lead you to victory. Feel like a hacker getting out of the JavaScript sandbox in order to read cookies, mine bitcoins, make a deface, or something else interesting.
And then I'll tell you how the sandbox works and give you some ideas for hacking.

Only 39% of the functions in node_modules are unique in the default Angular project created by ng new my-app.
I think the developers of open source solve problems in the same ways, because they study the same algorithms. Well, why be honest, they copy the popular solutions from StackOverflow also.

In 2013 Canonical tried to crowdfund Ubuntu Edge smartphone. Its main feature could be the ability to use the smartphone as a full-fledged PС. Unfortunatly, the crowdfunding campaign did not accumulate enough money, so a dream of having a universal device remained to be the dream.
I've been searching for universality, too, on the software side, not the hardware one. Today I can confidently say I found the necessary combination: Git and JavaScript.
As you know, I have already described the benefits of browser applications (nCKOB static site generator) and the benefits of using Git instead of yet another back-end with API (GitBudget to track personal spendings). Once GitBudget was out, I spent the remaining 2020 to build a system allowing one to create browser applications right inside browsers. GitJS is the name of that system.
I'm Ivan Kopenkov, a senior front-end developer at Mail.ru Cloud Solutions. In this article, I will tell you about the approaches we have used for the UI library components customization. You will also learn how to significantly decrease bundle size, cutting off all the unnecessary modules Ant Design takes there.
In our case, we are making wrappers for original Ant Design components inside the project, changing their appearance, and developing their logic. At the same time, we import both customized and original components right from the ant-design module. That saves tree shaking functionality and makes complex library components use our wrappers instead of original nested elements.
If you are already or about to use Ant Design, this article will provide you with a better and more effective way to do so. Even if you have chosen another UI library, you might be able to implement these ideas.

I now have a new shiny blog. Read this article with the latest updates there https://blog.goncharov.page/how-to-display-a-gazillion-of-metrics-and-keep-your-sanity
Large scale equals distributed. Distributed equals inevitable complexity. Complexity at runtime equals extensive monitoring. At Hazelcast, doing distributed systems well is our bread and butter. It means we have no choice but to be huge fans of collecting all kinds of metrics to stay on guard of the data our users trust us with.
In Management Center 4.2020.08, we drastically changed the model of how we transfer the metric data from the cluster members to the Management Center, how we store it, and how we display it. In this post, we are going to talk about the latter bit of the triad.
We will discuss what to do when you want to display all the data at once, but your users have a limited number of monitors and only one pair of eyes. We will speculate about what users actually want to see when they look at a chart of a monitoring web app. We will go over different approaches to filter the data, and how an average, a median, and a definite integral play their key roles.

Sometimes, when we surf dribbble, uplabs and similar design clouds, we often find many concepts or prototypes with animations, micro interactions, application flow and so on.
I often find illustrations of mobile apps that are good and interesting, but of course they are still in the form of concept, so therefore, why don't we try to apply them as an interface for applications that we will build next.
In the Dribbble Challenge we will try to build an interface for Coffee Ordering, as I found on Dribble.

JavaScript is a multi-paradigm language. It supports event-driven, functional, and imperative, including object-oriented and prototype-based, programming styles. JavaScript was initially used only for client side. These days JavaScript is used as a server-side programming language as well. To summarize in just one simple sentence — JavaScript is the language of the web.

Choosing between Node.js and Ruby on Rails, when choosing a development platform, is a core decision. That affects how the project unfolds over time, and how much server resources will be needed. Both languages can support web applications of high complexity, but each has its advantages and disadvantages. Knowledge of these pros and cons will help to choose the best solution for the proposed project. Let's analyze in more detail and tell you about our choice and experience.
In this tutorial you will learn how to use WebGL for image processing. We will cover basic stuff like initialization, texture loading, and simple fragment shaders. I will try to cover all aspects of interaction with WebGL but you should have decent understanding of vanila javascript. If you want more in depth explanations, there is a good book called "Learn WebGL", check it out.

Hi, folks, let me share my experience of creating an application to keep track of my spendings. Specifically, let me do it by answering the following questions:
1. Why keep track of spendings in an application?
I, like many people out there, wanted to become rich and successful. To become rich, one is often advised to run a personal budget, that's what I started to do several years ago. I'd like to point out that running my personal budget hasn't made me rich and successful, and I increased income simply by moving to Moscow.
