• What to think during NALSD interview

      There are a lot of posts about what a typical coding interview at Google looks like. But, while not as widely described and discussed, there is also quite often a system design interview. For an SRE position it’s NALSD: non-abstract large system design. The key difference between SWE and SRE interviews consists in these two letters: NA.

      So, what is the difference? How to be prepared for this interview? Let’s be non-abstract, and use an example. To be more non-abstract, let’s take something from the material world, such that you won’t be asked the exact same thing at the real interview (at least, not at the Google interview) :)

      So, let’s design a public library system. For the paper books, like you have seen everywhere around. The whole text below was written all at once within around one hour, to roughly show you the areas that you should be able to cover / touch during the interview. Please excuse some disorder, that’s how I think (therefore I am).

    • How to milk cows with robots and make an industrial startup of it. The history of the R-SEPT development

      • Translation


      In 2017, the media heard a very interesting story about a startup that robotizes milking cows on industrial dairy farms. The company is called R-SEPT, and back then it received 10 million rubles of investment. But a year has passed, and there's still no news on what happened further. We contacted Aleksey Khakhunov (AlexeiHahunov), the founder of the startup, and discussed the development. It turns out that the whole year his team was getting the prototype of the robot into shape, and just a week ago they conducted their first field test on the farm.

      Under the cut there's a story about a robotics student who grew up on his parents' farm, turned the University diploma into an industrial startup, as he collected the first manipulators with his friends, and then scaled up to the level of state programs for the robotization of agriculture. And the most important is how the iron hand of the robot and the machine vision are better than a living milkmaid.

    • Как спланировать двухнедельный спринт

        Иногда молодые команды разработки охватывает неразбериха.


        Это случается в тот момент, когда они ещё не до конца разобрались, что такое эджайл; проджект и продакт спорят, кто из них кто, а задачи каждый ведёт сам по себе. Или все уже всё знают, но планировать спринты не получается — задачи не прорабатываются, демо и ретро проходят нерегулярно.


        У нас тоже была похожая история, но мы нашли свой путь.


        Это рассказ от команды личного кабинета Яндекс.Кассы, и подробнейшая инструкция для тех, кто хочет улучшить своё планирование.


        Как всё было
