Let’s go into bits and bytes — For 50 years, from the time of Kernighan, Ritchie, and their 1st edition of the C Language book, it was known that a single-precision “float” type has a 32-bit size and a double-precision type has 64 bits. There was also an 80-bit “long double” type with extended precision, and all…

Solving complex NLP tasks in 10 lines of Python code — It is mostly true that NLP (Natural Language Processing) is a complex area of computer science. Frameworks like SpaCy or NLTK are large and often require some learning. But with the help of open-source large language models (LLMs) and modern Python libraries, many tasks can be solved much more easily…

How Safe is our Data in the Cloud? — When I was a young and naive IT student, I thought that digital photos are much more reliable than paper ones. They can be duplicated without quality loss, and so on. This is indeed true in the short term. But in the long term, it is not as easy. Practically…

Technological progress is going at a fast pace. Most people probably never realized that even the ordinary smartwatch nowadays has more computing power, not only compared to the NASA computer that brought Apollo astronauts to the Moon but also compared to some vintage professional laptops. Can we use this power…

Reading, collecting, and analyzing data from the MPU6050 sensor — MEMS (Micro-electromechanical Systems) sensors are widely used in different applications, from game controllers and smartphones to unmanned aerial vehicles. …

What kind of photos will you expect to get if you put your smartphone in a black box and start the camera in interval shooting mode for an hour? Definitely, most people would not guess the right answer, which is in the title of this story. Indeed, when most people…

BlackBerry was a very interesting brand in the mobile phone industry. At the peak of its popularity, in 2011, a Canadian company called “Research In Motion” had 85 million smartphone users worldwide, and only several years later, those numbers drastically declined. Within only several years, the market share decreased from…

Comparing Google Sheets and Pandas Approach — It is always nice to process the data using modern tools like Pandas or Jupyter. But let’s imagine the case when a colleague or friend asks to make a data analysis, but he or she is not a technical person, does not use Python or Jupyter, and does not have…

Running the object detection model on the low-power devices — In the first part of this article, I tested “retro” versions of YOLO (You Only Look Once), a popular object detection library. The possibility to run a deep learning model using only OpenCV, without “heavy” frameworks like PyTorch or Keras, is promising for low-power devices, and I decided to go…
