While video-based learning continues to rank high in the latest trends, there are a few points that are regularly overlooked in the production of learning videos, with a focus on user experience (UX) and user interaction
People really enjoy watching videos. According to a survey conducted among consumers worldwide, respondents watched an average of 19 hours of online video content per week in 2022. And nearly half of all internet users watch online videos at least once a week.
The Challenge of Mandatory Learning
Once we had several mandatory learning courses designed to be passed successfully by all employees. Still, many of them struggled to do so. Reminder emails to all participants could not solve the issue. And that is when my team was summoned to develop a thorough plan to reduce the number of overdue courses to a minimum. Of course, we were asked to develop something fun and engaging.
Uncovering the Root Problems
While working on the project, we managed to uncover several problems with course assignments, including the fact that they were not offered just in time, there were too many of them, and all of them had different due dates, which made it impossible to remember when to complete them. Additionally, we found that the content itself was often dry and unengaging, further contributing to the lack of motivation among employees. Finally, we came up with a system of notifications that included clear explanatory reminder emails, an escalation system, and a redesign of the course content to make it more interactive and relevant to employees' daily work. The result was almost no overdue courses after system integration.
The Myth of Mandatory Fun
So the case first seemed to be about motivation and engagement, but it is actually about smart course design that allows people to worry about work tasks instead of worrying about course assignments. It's also about creating content that resonates with the learners and helps them see the value in the training.
За последнее время я вижу всё больше споров на тему двух популярных GitOps инструментов: Argo CD и Flux CD.
На самом деле я считаю такие споры необоснованными, потому что глубоко убеждён что внимания заслуживают оба инструмента и каждый из них хорош для решения своего круга задач.
В своей профессиональной деятельности я активно использую и тот и другой. Я хочу поделиться с вами своим мнением и кейсами использования. Надеюсь эта статья поможет вам выбрать наиболее подходящий инструмент под ваши нужды.
Picture this: A thriving e-commerce platform faces a constant battle against fake reviews that skew product ratings and mislead customers. In response, the company employs cutting-edge algorithms to detect and prevent fraudulent activities. Solutions like these are crucial in the modern digital landscape, safeguarding businesses from financial losses and ensuring a seamless consumer experience.
The industry has relied on rules-based systems to detect fraud for decades. They remain a vital tool in scenarios where continuous collecting of a training sample is challenging, as retraining methods and metrics can be difficult. However, machine learning outperforms rules-based systems in detecting and identifying attacks when an ongoing training sample is available.
With advancements in machine learning, fraud detection systems have become more efficient, accurate, and adaptable. In this article, I will review several ML methods for preventing fraudulent activities and discuss their weaknesses and advantages.

In the software development industry, a lot of time and resources are spent on meetings. Many managers have calendars filled with meetings most of the time.
According to a study by Atlassian, the average worker spends up to 31 hours a month on unproductive meetings. That's about 8 hours a week, which is equivalent to a full work week for one employee out of a team of five people every month. If we convert this into working days, it means that on average four people are working, and one is constantly in meetings. This does not take into account additional time spent on informal discussions and ad-hoc meetings, which further reduce the time available for direct work on product creation. Thus, developers actually spend less than half of their working day on direct development, which is a worrying sign for any organization striving for innovation and efficiency.
Personally, I don't like meetings. I always try to minimize communication if an issue can be resolved without a face-to-face meeting. I apply this rule both at work and in life. For example, I prefer to refuel my car using an app, and I try to order food and other services without needing confirmation from an operator, and I did this even when such an approach was not so common. If I need to find a place, I will open a map in the app, instead of asking passers-by for directions.
My reluctance to waste time or be inefficient has resulted in our software development department carefully monitoring the time our developers spend on meetings. On average, a developer has only 2 hours and 15 minutes of mandatory meetings per week, including four 15-minute stand-ups, a 30-minute one-on-one meeting with a manager every two weeks, and 60 minutes for various meetings such as planning and demonstrations. The rest of the time, about 5 hours and 45 minutes, is spent on other activities in MS Teams, including chats and individual calls. Although we believe that this time should also be optimized, we focus mainly on key meetings to ensure that every minute spent is valuable.
In this article, I will consider the approaches I use and the ideas that motivate me to minimize the costs associated with meetings.
How to understand when proxies are lying: verification of physical locations of network proxies using an active geolocation algorithm
People all over the world use commercial proxies to hide their true location or identity. This can be done to solve various tasks, including accessing blocked information or ensuring privacy.
lsFusion platform is designed for rapid development of business applications. It is distributed under the terms of a Lesser General Public License (LGPLv3). The source code of the platform is available on Github.
lsFusion is best suited for creating complex systems with large numbers of entities and forms, where users need to input and process large amounts of data. However, the platform can also be used to quickly create simple applications instead of spreadsheets when Excel’s functionality is not enough.
At the same time the use of the platform will not give a great advantage when developing applications aimed at interaction with a large number of “external” users or without the need for any complex calculations. You should also take into account that the web interface is a single page application using JavaScript. Therefore, the lsFusion platform is not well-suited for creating websites, for example.

Understanding valid/ready protocol is extremely important for every microarchitect.
Valid/ready is one of the main protocols used to organise flow-control inside a logic block as well as on inter-block (SoC) level.
In the last lesson, we explored FIFO buffer using hdlgadgets - human-in-the-loop HDL training tool.
This time we will take two FIFO buffers (which form a pipeline with valid/ready handshakes) and will experiment with it by changing flow-control logic of the pipeline.
We will show that valid/ready is not only a mechanism for transferring data from one FIFO queue to another, but also a method for organizing various kinds of logical functionality between queues.
If you have not worked with valid/ready protocol before, you will be surprised how easy it is to achieve desired functionality of the design by simply writing couple of lines of Verilog code in the handshaking logic block between two FIFOs.

For a while I’ve been thinking of writing a scientific article. I wanted it to have certain utility.
Morse code is binary: it takes only two values – either dot (short) or hyphen (long). I figured out that short (s) can stand for two-eye blinking whilst long (l) can indicate left-eye blinking. Another question emerged: how to understand when does one-symbol recording stop?
Empty space between two symbols can be presented by right-eye blinking – r. If I input singly symbol of short (dot) and long (hyphen), I will blink my right eye once to indicate the space between two symbols.
To separate independent words, one has to blink her right eye twice and get rr.
Hence, I have collected an ordered set of symbols – r, l, s, - that can be converted into a full-fledged text. Once I accomplish the transformation, I get an answer.
OpenTeleletry Collector is an open source data collection pipeline that allows you to monitor CPU, RAM, disk, network metrics, and many more.
Collector itself does not include built-in storage or analysis capabilities, but you can export the data to Uptrace and ClickHouse, using them as a replacement for Grafana and Prometheus.
When compared to Prometheus, ClickHouse can offer small on-disk data size and better query performance when analyzing millions of timeseries.
Modern product development demands more and more sophisticated designs. This in turn leads to the increased complexity of both demand and implementation. Business is flooding the architecture and development teams with the new and changed requirements. Development teams are struggling to understand what the business demand is and find the best product increment strategy. One of the widely adopted conversational methods is the Use-Cases. This guide is intended to shed light on the process of the requirements development and maturing.
