Lectures

In this lecture, you will learn how a programmer’s career is built: from the first steps to the senior level, what salaries exist in the industry, how to choose a development direction, what career branches exist, and why programmers are often happy and in demand. The material will help you understand how to plan your professional growth and what you can realistically achieve in 5 years in IT.

In this lecture we break down Go’s built-in function copy: what exactly it copies (and what it does not), how many elements it moves, what it returns, why len matters more than cap, how to make a “real” slice copy via make + copy, and how to use overlapping copies for shifts inside the same backing array (delete/insert via shifting left/right). At the end: common mistakes and how to spot them quickly.

In this lecture we break down the Go built-in function clear: what exactly it does to slices and maps, why reducing len does not erase data from the backing array, how the “tail” can lead to logical bugs and memory retention (via references to strings/slices/maps), and what practical pattern to use for deleting elements: copy + clear + a new len.

In this lecture we break down what “removing an element” from a slice in Go actually means: shifting data and changing the length. We’ll see how to do stable remove (preserving order) via copy or the append pattern, and how to do unstable remove (not preserving order) via swap-with-last. We’ll also discuss why clear is often written next to removal, how the tail of a slice can keep memory alive, and what mistakes are most common when working with indexes and len.

In this lecture, we cover practical techniques for working with slices in Go: how to insert an element at an arbitrary position using the append + copy combination, how to insert a block of elements (expanding with make), and two approaches to filtering—creating a new slice and in-place compaction via out := s[:0]. Separately, we’ll discuss the “tail” of the backing array and why you sometimes need clear.

We break down Go’s standard library package slices and three of the most practical functions for working with slices: slices.Delete, slices.Insert, and slices.Clone. Using a todo list based on []string, we’ll see how to safely delete ranges [i:j), insert items at a position, and make an independent copy, and we’ll also go through common mistakes (including “zombie slices” and shadowing via :=).

In this article, you will learn how artificial intelligence has transformed the IT job market: why the largest corporations are fighting for AI talent, what kinds of compensation top specialists are being offered, how the role of universities and open source is changing, and what it means for everyday programmers. Welcome to a new era where brains are the most expensive currency!
