Development

Знакома ли вам ситуация, когда вы спокойно работаете, а клиентская служба передаёт вам странный репорт: несколько пользователей жалуются, что в приложении не грузятся картинки, но у вас всё работает. Или пользователь пишет в Google Play, что приложение занимает несколько гигабайт, и вы не понимаете, сколько таких пользователей и что с этим делать. Нужно ли срочно бросаться чинить, или это может подождать следующего планового релиза?

Согласитесь, было бы здорово узнавать о проблемах раньше, чем пользователи начнут жаловаться в поддержку. Сегодня я расскажу, как мы в Циан создавали Техническую Мобильную Аналитику (ТьМА) и получили возможность в любой момент времени ответить на вопрос: «Всё ли в порядке с приложением?»

Today, we'll explore Cursor AI. Whether you're an experienced developer or a beginner, this article will be helpful because this tool will change how we code.

Conclusions

Over the past two years, artificial intelligence has become one of the main topics in the media and many famous people have expressed their thoughts on this topic. But if you start searching on the Internet for collections of quotes about AI, you will mostly find quotes from CEOs of multi-billion dollar companies, futurists and scientists conducting research in this field. Moreover, these collections are so similar to each other, which sometimes gives the impression that they were compiled by AI. In this article, I have collected quotes from world famous people who are usually not included in such collections of quotes:

Are you tired of writing messy and unorganized code that leads to frustration and bugs? You can transform your code from a confusing mess into something crystal clear with a few simple changes. In this article, we'll explore key principles from the book "Clean Code" by Robert C. Martin, also known as Uncle Bob, and apply them to Python. Whether you're a web developer, software engineer, data analyst, or data scientist, these principles will help you write clean, readable, and maintainable Python code.

My name is Paul Karol and I work as a director in a Russian IT company that mostly sells their products in the international market.

I have been deeply involved in a project and I haven’t had time to write here lately.  

But out of this work came an understanding of two very large Mistakes that are being made that prevent your pre-sales from succeeding. 

I’m going to go into deeper detail on each one of these issues in the next articles, but I will introduce them here now.

Let me make you a promise….. if you correct these two issues, your software and development projects will sell.  

**I have a proven track record. If these areas are fixed the company begins to sell 150 % more than they’ve ever sold in the past. 

150% more profits! 

Hey! My name's Kirill Ziborov and I'm a member of the Distributed System Security team at Positive Technologies. In this article, I'll be continuing the discussion of methods and tools for the formal verification of smart contracts and their practical application to prevent vulnerabilities. The main focus will be on the deductive verification method, or more precisely, the ConCert framework for testing and verifying smart contracts.

I came across a script on the Internet that allows you to parse product cards from Amazon. And I just needed a solution to a problem like that.

I wracked my brain while looking for a way to parse product cards from Amazon. The problem is that Amazon uses different design options for different outputs, in particular – if you need to parse the cards with the search query "bags" – the cards will be arranged vertically, as I need it, but if you take, for example, "t-shirts" – then the cards will be arranged horizontally, and in such way the script falls into an error, it works out opening the page, but does not want to scroll.

For one of my projects I was exploring Reddit to understand how players create characters in video games, what is important to them in this process, and what their preferences are. It turns out that communities sharing their creations or seeking help with specific character designs remain active even for games released years ago. This realization sparked the idea for a hobby project that could assist these players in creating the characters they envision.

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.

Today, I would like to share a simple tutorial on how to set up authentication in your Next.js project using Firebase. This guide will walk you through the process step-by-step, ensuring you can quickly implement a secure authentication system.

According to the description,

Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited.

But how does Tree-sitter handle languages that require a preprocessing stage?

I recently stumbled upon a package called dart_mappable, and I feel compelled to share what I liked about it. If you're involved in Dart or Flutter development, this might be of particular interest to you.

In this article, I'd like to share my top 5 tools that have helped me become more efficient and faster as a web developer. You may already use some of these tools, but others could be new. Read the article to the end to make sure you don't miss the most essential tool :).

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!
