ChatGPT-4, the latest model from OpenAI, boasts impressive capabilities like text generation, question answering, problem-solving, coding, and even image analysis. However, accessing it requires a $20 monthly subscription on OpenAI's website. For residents of certain countries, accessing the service poses additional challenges due to restrictions, necessitating the use of foreign payment methods and VPNs.

We've created a list of the top-4 services that offer completely free access to ChatGPT-4. This article will delve into the advantages and limitations of each option, comparing them side-by-side.

Secret Management and Why It’s Important

Hi! My name is Evgeny, and I work as a Lead DevOps at Exante. In this article, I will discuss the practical experience of setting up a high-availability HashiCorp Vault with a GCP storage backend and auto unseal in Kubernetes (K8s).

Our infrastructure used to consist of thousands of virtual and physical machines hosting our legacy services. Configuration files, including plain-text secrets, were distributed across these machines, both manually and with the help of Chef.

We decided to change the company’s strategy for several reasons: to accelerate code delivery processes, ensure continuous delivery, securely store secrets, and speed up the deployment of new applications and environments.

We decided to transition our product to a cloud-native model, which required us to change our approach to development and infrastructure. This involved refactoring our legacy services, adopting a microservices architecture, deploying services in cloud-based Kubernetes (K8s), and utilizing managed resources like Redis and PostgreSQL.

In our situation, everything needed to change—from applications and infrastructure to how we distribute configs and secrets. We chose Google as our cloud provider and HashiCorp Vault for secret storage. We've since made significant progress on this journey.

Why HashiCorp Vault?

There were several reasons:

In this article, I would like to introduce a new web browser called Ladybird. This ambitious open-source project aims to revolutionize the browsing experience. Although it hasn't been officially released, I had the opportunity to test it on Ubuntu. In this article, I'll show you what it looks like and explain how you can run it on your computer.

At some point while diving deeper into automation processes you are faced with the need for data labeling, although just a couple of weeks ago, the phrases data labeling and you were standing at a party called "Earnings on the Internet" in different rooms. Or it would be better to say that you were standing by the pool, and the data labeling was on the third floor, smoking on the balcony with experts in the field of machine learning. How did we meet? Probably, someone pushed it off the balcony into the pool, and I helped it out, soaking my clothes along the way.

I’ve been wanting to sort it out about String memory optimization and all these ways to improve the performance and memory usage for Collections and Arrays in C#(as you remember String is an array of chars, loaded a bit differently but anyway) code. I finally managed to find some time to dive deeper into the System.Span.

I have put together this guide to share what I’ve learned. It’s filled with practical tips and examples to help you leverage Spans in your own projects. If you want to optimize your C# code, this guide is a great place to start!

Code Push in Flutter

In the fast-paced world of mobile app development, the ability to quickly push updates to users is crucial. Enter Code Push - a game-changing technology that allows developers to update mobile apps instantly without going through the traditional app store review process. This article explores how to implement Code Push in Flutter applications using Shorebird, a powerful tool that brings this capability to the Flutter ecosystem.

On July 19, 2024, Microsoft's Azure cloud services experienced a significant outage, causing widespread disruption. This incident affected multiple Microsoft 365 applications and impacted various industries globally. Here's what developers need to know:

Today, a significant portion of all content on the Internet is distributed with the use of CDNs (Content Delivery Networks). At the same time, there is no research on how various censors extend their influence on such networks. Scientists from the University of Massachusetts analyzed possible methods of blocking CDN content using the example of the practices of the Chinese authorities, and also developed a tool to bypass such blocks.

We (specialists from proxy service) have prepared an overview material with the main conclusions and results of this experiment (translate of this material).

In this tutorial, I’ll show you how to deploy a full-stack JavaScript web app into Firebase. We’ll deploy a Next.js application to Firebase hosting. I’ll show you a quick and efficient process that can be completed in 5 minutes. 

Corporations that dominate the market can impose their conditions on customers. This is also the case with everyone's favorite Netflix. When you make good content and you are sure that your audience wants to consume your content, you can start to increase the subscription price gradually. But the distribution of subscription costs around the world is unequal. This happens not only with Netflix, it happens with many big corporations: Microsoft, Sony, etc.

Naturally, everyone wants to watch high-quality content, but no one wants to overpay for it. And that led to creation of different schemes, for example, the one I'm going to describe here.

The essence of the scheme is simple – you buy a subscription for another region while staying in your home region. Of course, you can do this, but before I describe the scheme in detail, you should understand that Netflix is not as simple as it seems. When buying a subscription, for example, as a user from Pakistan, you should know that only the content that is allowed in that country will be available to you. Meaning, any sign of eroticism in movies, for example, is forbidden there.

And now this scheme appears in a completely opposite light. You can use my scheme if you want to access content that is blocked in your country, but you need to be prepared that the price will not be the same as for your region.

Top Three cheapest countries (in terms of the Netflix subscription price)

We are requesting 20,000,000 euro to place 900 orders on the exchange. What could go wrong?

Today, I will explain how to avoid losing billions in client money when executing large transactions on the exchange. This discussion focuses on an often overlooked and largely invisible problem that arises when handling large requests, particularly HTTP requests, which may not be fully executed. It's surprising how little attention is given to this issue and how few tools there are to address it.

Our task was to implement large-scale management of exchange orders, not just within a single exchange but globally, and to ensure it operates reliably. In this story, you'll encounter clients, servers, and cats. Stories are always more enjoyable with cats.
