How is the backward pass performed in MADDPG algorithm from MARL
I'm using the MADDPG algorithm from https://github.com/openai/maddpg/blob/master/maddpg/trainer/maddpg.py. I understood the forward pass for both the actor and critic networks. I'm not able to understand how the actor and critic networks are updates. Like at line 188 and 191 the authors compute the critic loss and actor loss. But can anyone explain how the critic and actor networks are updated. Also, as far as I understand, when the number of agents increases from 3 to 6 for a simple spread poli
5 reasons devs should be using modular frontends
Monolithic architecture is like, so 90s.
Step into the 2020s with modular frontend architecture and reap all the rewards along the way.
In this piece, we’ll break down what modular frontends are, and then give all the benefits they bring to individual developers and businesses alike.
Modular frontends definition
In the modular approach, we use “routes” which allow you to run as many apps or pages as you want under each route. Think of a route as a subpath of a website. And si
What is Angular web framework?

Prerendering in Angular - Part IV
The last piece of our quest is to adapt our Angular Prerender Builder to create multiple folders, per language, and add the index files into it. Hosting those files depends on the server we are using, and we covered different hosts back in Twisting Angular Localization post.
If you are going to make the best use of this article, I suggest you read the above post first.
At this point, I understand how reliant I have become on older posts, to release the dependency as much as possible, I will u
Learn CSS Basics
When styling a web page, there are many types of selectors available that allow developers to be as broad or as specific as they need to be when selecting HTML elements to apply CSS rules to.
Here you will learn about some of the common CSS selectors that you will use as a developer.
Element Selectors
The element selector allows developers to select HTML elements based on their element type.
For example, if you use p as the selector, the rule will apply to all p elements on the webpage.

Rails Many-to-Many Relationships
When programming in Rails, there is numerous relationships to learn. One of the most common is the Many-To-Many relationship. There's no question if you program in Rails, this is a association you must know. A Many-to-Many relationship consist of utilizing the has_many :through association. For this to work correctly, you will need two models and a join model. In our example models, we will use Student, House, and Sorting_hat as our join.

JavaScript forEach() vs map() & flatMap()
Nos dias atuais quando trabalhamos com arrays, é essencial sabermos iterar por eles e quais métodos devemos utilizar. Para isso, em JavaScript, temos métodos que podem ser úteis: forEach(), map() e outro método chamado flatMap() e é sobre isso que falarei nesse post.
Primeiro, para começarmos, precisamos entender como eles funcionam.
1. forEach()
Considere o seguinte array de números:
const arr = [1, 2, 3, 4, 5];
Utilizando o método forEach(), podemos iterar sobre o nosso ar

DevOps In Daily Life: Part 1
The time of year when I am applying to several internships. I'm browsing several blogs, YouTube videos, and feedback from various sources. To get the perfect output of "How to create the ideal resume and cover letter?" This is not a blog where I teach you how to write the perfect the professional documents(pro-docs like resumes and cover-letters). Instead I will help you save some time
I usually spend an hour or so researching and developing pro-docs rather than spending a whole day on it. Sinc
Start Reinventing the Wheel, Maybe Your Wheel will be better than a Rocket!
When I started writing my own framework, a lot of people started questioning me, why should anyone use mine over a popular framework like Nextjs, which is backed by a lot of tech giants and even backed by Vercel, compared to my framework only being worked on by me?
Since I couldn't answer them that time since my project was relatively new, It's time to show how reinventing the wheel makes my version of wheel much better than the good-ol' wheel we used to know and use...

[TypeScript-JSON] Developed runtime type checker (validator) library
https://github.com/samchon/typescript-json#runtime-validators
I'd hoped very strong runtime validator library which can support every TypeScript type specs, but there had not been such library. Therefore, I've been developing such library by myself, for a long time.
During one year development, I've succeeded to implement such full-spec runtime validator library.
Now, my library typescript-json is the only one which can validate every TypeScript types. The every TypeScript type means that eve
5 Best Logging Solutions for Java
What is Logging in Java
Logging is the process of recording the application insights as a readable log file. It is an important requirement for any application since it helps identify issues and fix bugs in applications while improving performance.
Logging frameworks are similar to the daily diary of a web application. They keep track of activities, errors, and sensitive details of internal processes. Therefore, picking the most secure and reliable option is crucial when selecting a

🤯 Wait... You’re building a code simulator?!
If you’ve been following me on Dev.to for the last few months, your probably asking yourself- where have you been? Well, I’ve been busy running a non-profit and so haven’t had the time to write. Sorry!
But, we’ve been working on some cool stuff and through the next couple of days we are going to be sharing it- so stay posted.

We’ve been working on a system similar to Repl.it but we came upon a realization: we need to run the code that people write with our tool. So,

Adding feature to a project
Hello!
Static site generator feature
This week I've been working on another student repo. I had to make a feature that will allow user to specify all of their SSG options in a JSON formatted configuration file instead of having to pass them all as command line arguments every time.
It didn't took much time to understand how things work, since I was writing a code in the same language, that I'm familiar with(JavaScript).
