Around 4 million employees left their jobs in July 2021. Most of them are senior developers. If pandemic didn't cause it, who did?

One reason is the ridiculous entry barriers put by tech companies — even in the smaller and mid-sized firms.

• All companies (regardless of size and paycheck) make competent developers go through grueling 4–7 rounds of interviews.
• A verifiable track record is overlooked, while CVs filled with adjectives top the stack.
• The whiteboard interviews test reproducibility of the solutions, not the actual understanding.
• The verbal interviews (+personality tests) are formulaic, and one can rarely get past them without lying about their careers.
• Instead of one competent developer, companies hire 3 inexperienced programmers who are ready to jump the ship within 2 years, leaving huge tech debt for the next troubleshooter (mostly senior) guy.
  There is also rampant ageism in tech. And age-discriminated programmers are those without any representation. Their only way to raise their voice is to revolt, and quit.

As a result, senior and competent developers (age group 30–45) no longer want to join another company. They want to roll out their own business.

Your Instagram feed may tell you that the line spacing should be 20% more than the font size. You may see that the difference should be as much as 50% as well.

There is no magic ratio. Text blocks will look different with different typefaces because of differences in Cap Height and X-height. While 120% is very likely to work for interface fonts — because they were created with a certain Cap to X-height ratio — the rest are problematic.

To solve the problem, you should not use a common index for all fonts, but an individual one, depending on its X-height. It is necessary to take a lowercase letter without extensions — for example, N — of the same point size as the typed text, and put it between two lines of text so that the upper boundary of the letter touches the typing line of the first line, and the lower boundary touches the upper height of the uppercase letter.
