Continuous socket connection can be crucial to ensure correct app behavior. Whether it’s delivering real-time chat updates, stock prices, or in-app indicators, a reliable connection is vital.

One of the irritating problems with sockets is a sudden loss of connection. If the true cause is not visibly evident, i.e., unstable internet connection, then the disruption cause is often well hidden. To tackle this issue we can implement an automatic socket reconnection strategy. Let’s see what options we have in the industry-standard socket library for Dart — web_socket_channel.

Million Dollar IT Sale…..Lost

Lose Your Sale) How to lose an IT project sale. 

My name is Paul Karol and I work as a director in a Russian IT company that mostly sells their products into the American Market. What we will discuss today was so costly for that company that I want to share this knowledge so that it doesn't happen to other Russian IT companies. 

Case Study

Today I want to tell you about a sale that almost was. I was Consulting for this one company and they were involved in selling software to the United States. This one particular client was in contact with the sales manager for 2 months.

Now this sales manager was very good at their job and they had a lot of charisma on the phone and in the text messages. However they specifically did not know something that cost them a large contract. 

1. In Russia it's respectful not to talk about your personal life because you feel that you're wasting someone's time if you do not know them well. 

2. In the United States once you have been talking with somebody for a couple of months you would start to consider them sort of a friend. 

The Russian IT sales manager had not been in contact with this client for about a week and this was unusual. 

They were worried. 

Then the text message came that said this. 

"I'm sorry Marina that I have not been in contact with you for some time. I took my family and kids to the Lakeside and we enjoyed some time by the beach." 

The Russian IT sales manager did not know how to think about this and they asked this question. 

" So, do you want to buy our product?"

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.

Managing AWS Auto Scaling Group Instance Refresh: The Harmony of Terraform and Ansible

Level of difficulty Medium
Reading time 6 min
Views 525

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...

After sale IT support for American and Western Companies

Reading time 2 min
Views 448

Title:

After sale IT support for American and Western Companies 

Let’s have a case study. 

A Russian IT company sells software to a western country like say America. And you are working as an application developer on the support side. 

One day, there is a problem with the program, and the program has stopped working. 

You must contact the company now to inform them that the program is off-line. 

THE NEXT STEP YOU TAKE IS VERY IMPORTANT. 

The way, the two cultures operate in a situation like this are very different and it will have everything to do with how easy your job goes for you.

…………

Russia : “we have a problem”

“What is wrong?”

“I don’t know”

“When can it be fixed?”

“I don’t know”

……………

USA: “i’m just giving you a real quick call to let you know that there is a problem with the program. 

I’ve already put my team on it and we will have it up and running shortly. 

I will let you know more by 3 o’clock today what is going on”

It’s not important how long you think it will take you, but I will always tell them a few hours from the time that you informed them of a problem.

I understand that you have no idea how deep the bug is and also whether it will affect any other systems.

But it is important to set a time window very close to when you inform them that you will bring them more information. 

This also works very well if you don’t know something that they ask you.

Question:

“What can we do to fix this problem?”

Answer: 

“I understand what you’re saying. I will look into it and get back to you in two hours.  By 1 PM today.”

in this case, it’s important that you: 

1. Take responsibility for yourself and your team.

   2. Communicate that you understand this responsibility.

   3. Gives strict timelines. (if it’s not possible, you can always say that there is a problem, but do it before the deadline.) 

    4. Use certain key language.

“ I understand you”

“ I understand what you were saying”

“ I wanted to inform you”

“ we are working on it right now”

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.

Your Name: Why it’s Important in American Sales and Marketing

Reading time 2 min
Views 796

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.

Marketing your Mindset

Information shared below is exactly how I work with my IT professionals who are going to be participating in pre-sales to America. I tell them exactly this, and it helps prepare them to successfully sell the the United States companies.

As developers and IT companies, we must sell our software.

What can give you an edge in this very competitive market place?

Please, if you would allow me to let me explain why this is important and how this can make your company more successful. There’s a certain type of thinking that is conducive to working as a software developer. This is a very practical mindset, but it goes beyond that. If you have the mindset of direct thinking.

Here are examples:

I see the target a target and I don’t see obstacles

Вижу цель, не вижу препятствий

This is an example of the practical mindset, how is approaches the problem of development. It makes people who have this mindset, the best developers in the world.

Example of mindset:

Problem……………… find a solution………… No problem.

Notice how this looks exactly like a line of code?

This is well-known around the world in places where you would like to sell your software, the United States, Germany, Belgium, and the Middle East.

Countries where people have this mindset have the best developers.

now let’s talk about your competition:

Americans: during the center process, “find a solution” Americans are overly concerned about responsibility. This slows them down in the decision making process.

The key to Sales Conversion of an American CEO or CFO

Reading time 1 min
Views 667

i’m writing this series articles to spearhead the new marketing campaign for into the American market. I will be covering a wide range of topics that will allow us to position the company in the proper way so that is excepted as a provider of High-quality software in America.


The key to converting an American CEO or CFO is the trigger point for the American business culture. The trigger point for America is responsibility.   This means in business you must be responsible. You also look for business partners that are responsible.  


But let’s take this into the newest more powerful view that we need to have now.  

The scene from the point of you of the CFO sitting at the head of the financial controls of a large hospital conglomerate. Put yourself in the mind of the CFO. What are they concerned about?  


As an American CFO they will be very concerned about whether they are being responsible in their job and responsible to the hospital, staff, shareholders, patients and the management above them. 


And this is how we get our foot in the door in this American niche market. If we present ourselves as offering something that “May” give an answer to specific problems that they know that they have, they must give us a chance to present a Presale. The reason is because they are responsible, and if there is a solution as an American Director you must explore that solution.


It would be irresponsible to not explore a potential solution.



Then it’s a simple case to actually give value in the presale meeting and convince them that we can deliver some thing that will benefit their business and profits.
