Development

Launching a startup often means navigating through stringent constraints, particularly in the early stages where resources are limited. For technical founders, who usually possess deep expertise in certain technical domains, the inclination might be to hire a team of senior engineers—considering you often end up with only one expert in each domain, it might be risky to delegate entire segments to junior specialists.

This situation typically leads to a small team where each member is more skilled than the founder in their respective field. This raises an important question for the technical lead: what role should you play in this team? 

While the apparent answer might be task setting and quality control, prompting engineers to do what they love (coding), a less obvious but crucial role emerges. As a leader, your primary responsibility could be to prevent your team from engaging in unnecessary or potentially detrimental tasks, a concept known as "overengineering."

In this article, I will explore the critical role of a technical lead in steering a team away from overengineering and ensuring that their efforts align effectively with the startup's goals and resources.

Clean Go

Hey guys, I recently dove into 'Clean Code' by Robert C. Martin and found some valuable insights. The book is originally in Java, but I decided to reinterpret the principles in Go. Here's my take on the clean code concepts and how they can improve our coding practices.

1. Clean Code

The gist: Clean code is more than just working code; it's code that other developers can easily read, understand, and modify.

The team developing a set of portable SystemVerilog examples decided to organize the first event in Silicon Valley on Sunday, January 14 from 2PM till 5PM at Hacker Dojo in Mountain View, CA. If the first event is successful we are going to make it recurrent. You can register for the event on Meetup or LinkedIn.

The current directions of the group:

In this third part, we will discuss Machine Learning, specifically the prediction task in the context of information theory.

The concept of Mutual Information (MI) is related to the prediction task. In fact, the prediction task can be viewed as the problem of extracting information about the signal from the factors. Some part of the information about the signal is contained in the factors. If you write a function that calculates a value close to the signal based on the factors, then this will demonstrate that you have been able to extract MI between the signal and the factors.

Introduction to ADRs

ADRs are critical for documenting architectural decisions in software projects. They provide a historical record of decisions, rationales, and impacts, vital for future teams and stakeholders.

Defining ADRs

An ADR is a document capturing key architectural decisions along with their context and consequences. It helps stakeholders understand why certain choices were made during a project, promoting transparency and clarity.

What comes to your mind when you hear the word Telegram?

I wouldn’t be surprised if drugs, sex, or crypto are your first associations. Throughout the years, Telegram earned a shady reputation, perhaps not strategically, but for a “good” reason.

I feel like Telegram is a mystery. On the outside, it might be perceived as a platform designed for drug traffickers, crypto scammers, and sexual abusers.

I shared this feeling when I joined the early team of Bancor in 2016, as I also joined its internal group chat, needless to say, on Telegram.

However, the app was quickly removed from my list of stigmas. Instead, I started to appreciate Telegram for its well-crafted product and care for design. From its meticulous attention to small details to have a unique brand — it stands as a dogma of an opinionated product (and a company) in many aspects. In addition, it helped me recognize the benefits of separating my private and professional lives early on.

After using Telegram extensively over the past 7+ years, I feel the urge to write about it, but this time not in the spirit of its typical news headlines.

Introduction: In this guide, I explore the automation of reCAPTCHA solving in web scraping and testing scenarios using Puppeteer, a Node.js tool designed for browser automation. My focus is on the practical use of the puppeteer-extra-plugin-stealth plugin to seamlessly navigate through reCAPTCHA challenges.

In this article, I will cover the memory consumption of .NET applications on Linux. Firstly, we will try to understand the idea of virtual memory. Then, we will examine the memory statistics that Linux provides, such as RSS (Resident Set Size), VmData, RES (Resident Memory Size), and SWAP. Following that, we will delve into specifics related to the .NET.

In the DevOps realm, where automation is crucial, the management of resources and updating processes in the cloud is vitally important. Many modern projects, particularly in AWS cloud environments, leverage Auto Scaling Groups (ASG). This mechanism aims to achieve three key objectives: balancing loads, increasing service reliability, and optimizing operational costs for efficiency and effectiveness.

Imagine working at a company where you deploy applications on Amazon's resources. To streamline this process and manage configurations more effectively, you use pre-built AMI images. These are crafted with tools like HashiCorp Packer, ensuring your applications launch swiftly and reliably. For the actual infrastructure deployment, you turn to Terraform. It's widely recognized as the standard in many major companies for managing cloud resources and using the IaC (Infrastructure as Code) approach.

As an IT engineer, you sometimes need to update instance versions to a newer AMI image, either for the latest security patches or to introduce new functionalities. The challenge lies in updating an active ASG without causing downtime. It's crucial to ensure the new AMI performs as reliably as the existing one, balancing the need for updates with system stability and uptime.

ASG's instance refresh is a crucial feature that allows for updating instances within a group while minimizing downtime, thereby maintaining high availability. However, ensuring the success of such updates, especially in large, complex systems, can be a challenge. Terraform resources, such as aws_autoscaling_group, can initiate this process but don't provide progress tracking. This limitation becomes apparent when other infrastructure components, such as certificate renewals or DNS updates, depend on the state and version of the instances. Monitoring the update process is essential to maintain an accurate infrastructure state after Terraform's execution.

To overcome this challenge, Ansible can be utilized...

I based my approach on an English manual that caught my eye just a couple of days ago, and I decided to test it (since it's written by a captcha recognition service that I use, why not - by the way, guys from 2captcha - I accept thanks in the form of green bills, if you're interested))))

I've made some tentative attempts at automation and encountered a frequently arising problem: reCaptcha recognition.

Of course, I understand that there are many guides, manuals, and articles written on this topic, but let's agree - it's interesting to describe one's own experience.

Thus, without getting too lengthy and boring about why Selenium is necessary, how important it is for automation, when it appeared and who invented it, let's get to the crux:

To solve the problem, we'll use a demo page kindly provided by reCaptcha itself - https://recaptcha-demo.appspot.com/recaptcha-v2-checkbox.php:

The traditional definition for the operation of exponentiation to a natural power (or a positive integer) had introduced approximately as follows:

Exponentiation is an arithmetic operation originally defined as the result of multiple multiplications a number by itself.

But the more precise formulation is still different:

Raising a number X to an integer power N is an arithmetic operation defined as the result of multiple [N by mod times] multiplications or divisions one by number X.

In the realm of frontend development, the quest for enhancing user interaction remains a constant pursuit. Developers, inspired by innovation, often seek solutions to refine components for a seamless user experience. Today, we delve into the construction of an advanced dropdown component using Svelte — a framework known for its simplicity and effectiveness.

UX writing is an essential part of UX design, which plays a huge role in providing qualitative user experience. The job of a UX writer is to compose texts for a digital product, which can be of two types: microcopy (labels, buttons, notifications and other small notes) and macrocopy (larger texts like written content on pages, instructions, information sheets). UX writing helps users easily navigate through the product, perform various tasks and get all the necessary information.

This is one of the most important articles I’ve written. 

In this article, I’m going to dive deep into one of the largest differences between Russia and America pertaining to sales and marketing. 

1. You must use your name. 

2. You must have a personal approach. 

3. You must show that you are involved. 

4. You must show that you care about the needs and desires of the client. 

Recently, I was faced with an interesting problem. I was asked to call clients without making it personal. 

So let’s go back to when I was in America, living and working as a sales person. The company I work for, was very large, and had multiple branches around the Washington DC area. They had offices in three states. 

They put me through a sales training course. 

The biggest “take away” from the course….. 

You’re not selling the product/ 

you’re selling yourself. 

It's important to use your charisma and your genuine caring for the customer to win them over. Once they understand that you're actually trying to help them, then they will seriously consider the item you are telling them about. 

I also want to say, very clearly, that it's not a prideful approach. It should be a professional approach. You're responsible to tell the customer/ the client all the benefits of the item and how this item will help their business.

Everything above pertains to sales in America. So if you are approaching America as a sales manager this is how you should craft your approach. 

Now I've spoken to my colleague,

Kristina Pashnina and we have agreed upon some stark differences to the Russian sales climate. Here she will begin to tell you how the Russians see sales.
