There is such an interesting data transfer protocol - APRS. A lot has already been told about him on the Internet. There will be no in-depth theoretical material here. This article will describe how to create your own "pocket" AFSK modulator. In the following articles there will be instructions for going on the air and for creating a simple demodulator. Which will allow you to accept APRS packages and display information on the display right on the street. Everything will be implemented for Flipper Zero. If you don't have this gadget yet, then don't worry and try everything on the great and terrible Arduino. It is very interesting to transmit information at a distance "with your own hands".

Faced with situation when had to map STRING VALUE coming from database TO ENUM. The problem happens when value stored in database differs from enum name. And here we need a workaround to make a mapping. I will describe main points on how I was able to realise it.

LeetCode 2612 (Hard). Minimum Reverse Operations.

The algorithm follows a breadth-first search (BFS) approach to determine the minimum number of reverse operations needed to bring the 1 to each position in the array.

To speed up the algorithm, we mark banned positions with -2 instead of using set lookups. This optimization reduces the constant coefficient and improves the speed of the algorithm, but it may still result in a time limit exceeded (TLE) error.

For each visited position, there are potentially O(k) target positions that can be reached through reverse operations. To avoid the multiplicative cost of iterating over all these potential positions, we update the nextNode2s array. This array initially points forward by 2, but we update it dynamically to point beyond all the target positions considered for each visited position. This optimization helps improve the efficiency of the algorithm and avoids unnecessary computations.

AI technologies offer unprecedented opportunities for innovation, efficiency, and growth in such industries as advanced machine learning algorithms or intelligent automation systems. However, to harness the power of AI, effective communication becomes paramount.

The growing impact of AI in modern business is undeniable. Organizations leverage AI to automate processes, gain insights from vast amounts of data, personalize customer experiences, and make informed decisions. Yet, the complex nature of AI technology often creates a significant gap between AI capabilities and the understanding of its users.

Here the role of a technical writer becomes crucial. Technical writers act as a bridge between AI technology and its users, ensuring that complex concepts have a clear, concise, and user-friendly manner of speaking. They are the main participants in making AI accessible to a broader audience, facilitating adoption, and maximizing its potential.

Effective communication is essential to reduce the gap between AI technology and its users. While AI systems may be sophisticated and comprehensive, their impact can be weak without proper understanding and utilization. Technical writers contribute to the success of AI implementations by translating complex AI concepts into easily digestible documentation, user manuals, tutorials, and other communication channels.

Furthermore, technical writers understand the importance of tailoring information for different audiences. They communicate with non-technical stakeholders, including executives, decision-makers, and end-users, who may lack extensive technical expertise. Using the AI capabilities, benefits, and potential limitations, technical writers empower these stakeholders to make informed decisions and embrace AI solutions.

Generative AI is creating waves in the way we work, significantly revolutionizing the software development process. AI tools are appearing in various phases of software development, such as design, development, and testing. However, there aren't many tools specifically focused on software business analysis tasks.

But with a little creative thinking, we can put "one-size-fits-all" applications like ChatGPT to good use. It can definitely speed up execution of many typical tasks and free up analysts to focus on the more challenging, strategic aspects of the job.

I believe that every programmer has at least once heard about ChatGPT and its marvelous abilities to process, calculate and create huge amounts of data; if not, go check out this Wikipedia article - https://en.wikipedia.org/wiki/ChatGPT.

Can you imagine that some 50 years ago people could not even believe that there may be something artificial surpassing humans in so many areas? Nowadays, we have this marvel at the distance of a few tabs on a phone screen or a keyboard; however, there is still a sadly large number of people who do not fully—if at all— utilize all the perks of ChatGPT in their lines of work. This is mostly related either to people's reluctance to learn new technologies or the fear of losing coding skills they have previously gained—which is not the case with using ChatGPT properly.

In this article I want to give you some of the most useful uses of ChatGPT for your coding work. Remember, there is nothing shameful in using the AI, since this the development and further implementation of it in our day-to-day life is inevitable, so we should start adapting to it as early as we can to take the full advantage of this "magical" technology. Let's get started.

It hasn't been that long since my last cheat sheet was published and this is the day for the new one. This time I got a task to find a solution for backing up Kafka to S3 bucket, following the terms:

Hi, my name is Mikhail Emelyanov, I’m a Python programmer and I would like to show you my pet project — Flywheel, a micro-platform for learning foreign languages, a mixture of Duolingo and Anki, an application that can teach you to properly write in Spanish (or any other language you’re studying). Flywheel’s source code is available on GitHub.

As you may know, generalized knowledge of a foreign language can be broken down into four relatively independent components: reading, writing, listening, and speaking. Unfortunately, training one of these abilities has no direct effect on the other components, so, for example, by developing our reading skills, the effect on our writing skills is quite indirect. Flywheel is a ‘sharpener’ specifically for written Spanish.

If you’ve ever used Duolingo, you should have some idea of the format in which you’ll be studying. The formula is simple: here’s a phrase, translate it into the other language; the app will remember the last time you translated a phrase and how successful you were at it; and depending on the accuracy of your answer, it will determine when you should do the same phrase again. In my opinion, Duolingo and its approach are brilliant. However… There are certain aspects that somewhat spoil the learning experience, and Flywheel was specifically designed to address them.

I have been working in Agile since 2017 in several projects.
And I would like to note here a couple of moments from real experience through the eyes of developer role in project.
Hope it will be helpful for you!

Hello, my reading friends!

My previous post (rus) on Habr was about how the Business Continuity Management function started, as well as about its relations with other corporate functions. In fact, it was quite theoretical.

This time, I’d like to tell you about some practical vectors of procedures and tools implementation as regards to Business Continuity Management, or BCM, along with Operational Resilience, or OpRes. Plus some real initiatives that can follow the BCM & OpRes implementation in a company and the associated with it investigation of the corporate landscape and procedures.

In this article, I will cover basic work with MapView (and MapFragment) markers, learn how to implement marker clustering, i.e. group markers located close to each other, and display dynamic icons in the markers, i.e. load by url and display remote images. Ultimately, we will create such map with clusters and dynamic image loading (in background).

Solution of the day.
LeetCode 956 (Hard). Tallest Billboard.

The code uses dynamic programming to solve the problem. It maintains a dictionary dp, where the keys represent the possible height differences between the two billboards, and the values represent the maximum sum of heights achieved for each height difference.

Recently, The BCI, one of the leading institutes working in the field of organizational resilience and business continuity, issued its regular report BCI Operational Resilience Report 2023 in collaboration with Riskonnect, who work with risk management solutions.

One of the questions they asked the respondents was if there was a difference between organizational resilience and operational resilience. As the answers demonstrated, for most respondents (and in most companies) these terms were used as synonyms. Having studied the report, the colleagues brought up another matter – The BCI introduced the new term of "organizational resilience" in addition to "business continuity" and "operational resilience".

If we search Habr for "Business Continuity", "DRP", "BCP", or "BIA", we’ll find quite enough posts by my colleagues (I’ve met some of them face to face and worked with the others) about data system recovery, data system testing, fault-tolerant infrastructure, and some other things. Yet, hardly any of them explain where all of it has come from, how it is changing, where it is heading – and why.

I thought the time has come to change the situation for the better and answer some of the questions like where business continuity provisions and operational resilience has come from, how they are changing, and where this trend is heading and why. To share my thoughts about development of the industry and its current de-facto state in case of a mature (or not too mature) introduction level – some things I’ve stated for my own use.

Hash, salt, SHA-1, SHA-2, std::hash.. To a non-programming person that may come up as some kind of a recipe that just does not seem to add up. In a sense, this is indeed supposed to be a gibberish to any third party and a strong, helpful mechanism for us, programmers. 

At the start of writing this article, I had one clear idea to get across the table: to finally unveil this mystery of hashing in C++ for beginners. I, a beginner myself, also wanted to solidify my knowledge in this area; so let’s get started.
