Nothing and nobody will escape oblivion. Whatever you may say, the history of mankind is a history of automation and the subsequent evolution of workers. This happened both during the first industrial revolution and during the second. The same thing happened with digital revolution. Now machine learning and artificial intelligence are being implemented everywhere. What is the future of software testing?
Hello, Habr! Not only traders but also mathematicians and programmers work with stock markets. Director of Engineering at Luxoft Artem Sosulnikov tells about data, which specialists of quantitative hedge funds work with, things they pay attention to, and conditions in such companies.
There is a myriad of articles about where to find remote jobs, particularly in tech. Some of them are outdated and most of them don't provide detailed reviews. So that's why I decided to do my own research. I did a basic search by "React" skill (where possible) and expected to see mostly "Frontend Developer" vacancies.
It may seem that when you are a beginner, you'll do simple things only. No need to learn data structures and algorithms. No need to understand Big O notation, complexity and stuff like that.
This couldn't be further away from the truth!
In 2008, when I just started learning to program, I spent a lot of time reading books on PHP and MySQL. Months later, when I felt confident, I took my first freelance project. It was a real estate website. A simple one. I used a custom-made ORM and everything worked just fine!
When I released it, the search feature quickly became sluggish and made the website unusable.
I was wondering what the heck had happened. I figured out that database queries became very slow when there were over 200 real estate objects added to it.
This is it. What worked fine during testing did not work in real life.
I was a self-taught developer. I did not know how to measure if my project scaled well. I didn't even know that I had to do it.
I thought algorithms mattered only for launching a spaceship.
If I had some basic understanding of algorithms, I would have known that the more the input, the longer it takes.
I am not saying I would have come up with a robust solution as a junior, but I would have looked for a solution because I knew there would be a problem.
Please, don't make the same mistake!
Of course, data structures and algorithms are much more than that and they apply differently depending on what you work on.
But a basic understanding of data structures and algorithms is a must for every software developer.
Hey Habr! I'm Ruslan, a Java programmer with experience in IT of 15 years who still doesn't understand how to grow as a technical specialist in a company.

Why do some people get rich off of their ideas, and others are not able to reach even 100 customers? The renowned Stanford University, which is located in the heart of Silicon Valley, offers a course where students can learn the recipes for founding a successful startup. This course is also available as an audio podcast and on YouTube. Here are my takeaways from 20 lectures with such well-known teachers as Peter Thiel (PayPal), Paul Graham (Y Combinator), and Alex Schultz (Facebook).
