The article discusses several methods for determining the mathematical equation of a simple (pairwise) regression line. All the methods described here are based on the least squares method. We will denote the methods as follows: Analytical solution, Gradient descent, Stochastic gradient descent. For each method of solving the equation of the line, the article provides various functions, which are primarily divided into those written without […]

Hello, esteemed hub community. Yesterday (while inebriated), after reading a post by @arslan4ik titled "Why Do People Leave IT?", I pondered a truly good question: "Why...?" Given that I live in the sunny city of Los Angeles, I decided to find out if there are people in my beloved city who, for various reasons, have left (to the dark side of the force) the IT field. […]
In this article, I will share my personal experience of memorizing English words using the remarkable program with a non-obvious interface, Anki. I will show how to avoid turning the creation of new cards with audio for memorization into a routine. It is assumed that the reader already has an understanding of spaced repetition methodology and is familiar with Anki. But if not, it's time to get acquainted. Laziness for an IT person is […]
Jeff Marrison, the author of the x86_64 assembly language library HeavyThing released under the GPLv3, which includes implementations of the TLS 1.2 and SSH2 protocols, published a video titled "Why Write in Assembly?" The video presents testing results using the perf and strace utilities for a simple application (output 'hello') written in 13 programming languages. It actually compares the costs of […]
When you are on a phone call and another person tries to reach you, most smartphones and telecom operators inform that you are receiving a call. However, among VoIP services, such notifications haven't become widespread. Now, this feature is available to users of the popular messenger WhatsApp. It’s worth noting that the incoming call notification will not allow you to put the current call on hold. […]
The release of the speech recognition engine DeepSpeech 0.6, developed by Mozilla, has been announced. It implements the namesake speech recognition architecture proposed by researchers from Baidu.
