Development

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!

Riverpod is a powerful library that I like to think of as the Swiss Army knife of Flutter development. It offers elegant solutions for both state management and dependency injection, giving you the freedom to "cook" your app architecture just the way you like it.

Prerequisites:
1. Install Docker
2. Install VSCode

STEP BY STEP

1. Open VSCode that you previously installed and click on "Extensions" tab right on the menu bar, then type 'docker' to find proper extension and click "install":

Hi, I’m Nastya, the Product Owner of EXANTE’s desktop and web trading terminals. I began working at the company nearly five years ago as a Junior QA Engineer. Since then, I’ve advanced to QA Lead and ultimately to Product Owner. In this article, I’d like to share my growth journey within the company and the steps that helped me progress. I hope that my story will be helpful to those seeking to advance their careers but are unsure where 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.

Do you want to know how to build an AI image analyzer? Then read this article till the end! I'm going to show you how to build AI analyzer tools really simply, so you almost don't have to have any prior knowledge. I will take you step by step, and we will use Project IDX and the Gemini API. This means you don't have to set up anything; everything we will do is on the cloud. If you're ready, then let's get started!

Recently, there has been a lot of talk about the success of artificial intelligence (AI), although this usually means another achievement in the field of generative neural networks.

And few people, speaking about AI, try to explain what they themselves understand by the term “artificial intelligence.” After all, it’s one thing to write about “AI problems,” and quite another to endow an ordinary computer algorithm with at least the rudiments of intelligence.

After all, the etymology of the established phrase “artificial intelligence” is not unambiguous and can take on different meanings depending on what meaning the author is trying to put into it.

Quantum computers have gradually migrated from “natural” quantum objects like ions and quantum dots to “artificial” objects like transmons, where natural frequencies of LC circuit mimic energy levels. Coaxial cables attached to such circuits excite the system, read their state, and adjust their properties. They are still quantum objects and operate at low temperatures.

I wondered if a similar system can be built with large “classical” mechanical objects. Here I demonstrate 2 -qubit quantum computer built of coupled pendulums.

Gowin has clear advantages over Xilinx in the educational FPGA board market: Gowin boards are several times less expensive, the synthesis speed is several times faster, and the EDA package is two orders of magnitude smaller: we are talking about 1G versus 100G disk space. Of course, Xilinx is still the king of high-end prototyping boards that cost $10K-100K, but for the students such boards are irrelevant; such boards are for ASIC design companies. A beginning EE student needs a board for less than $100, and Gowin not only fits the bill but also covers all the needs, specifically:

In today's fast-paced world of software development, integrating third-party APIs and services is a common practice. These integrations can enhance functionality, improve user experience, and provide additional features that would be time-consuming and costly to develop in-house. However, ensuring these integrations work seamlessly with your software is crucial, and this is where the importance of a test environment, or sandbox, comes into play.

A sandbox environment allows developers to test the integration between their software and third-party services without risking the stability and security of the production environment. This controlled setting enables thorough testing, helping to uncover issues before they affect end-users. By covering as many test cases as possible, developers can ensure robust and reliable integrations.

But what if your third-party provider, such as a bank or government e-system, does not offer a sandbox environment? This scenario can pose significant challenges, but there are several strategies you can employ to mitigate these issues.

In this article, we are going to do something really cool: we will build a chatbot using Python and the Gemini API. This will be a web-based assistant and could be the beginning of your own AI project. It's beginner-friendly, and I will guide you through it step-by-step. By the end, you'll have your own AI assistant!

In this article, we'll explore Project IDX, a new code editor developed by Google. It has the potential to change the way we write and manage code.

Hi Everyone!

Machine Learning (ML) technologies are becoming increasingly popular and have various applications, ranging from smartphones and computers to large-scale enterprise infrastructure that serves billions of requests per day. Building ML tools, however, remains difficult today because there are no industry-wide standardised approaches to development. Many engineering students studying ML and Data Science must re-learn once they begin their careers. In this article, I've compiled a list of the top five problems that every ML specialist faces only on the job, highlighting the gap between university curriculum and real-world practice.
