Trigger warning: скрепы.
TL;DR: Я сделал механическую игрушку на российский конкурс, и это была очень сложная инженерная задача.
Несколько месяцев назад Российское Общество «Знание» объявило конкурс «Родная Игрушка»: нужно было отправить идею какой-нибудь куклы, модельки, конструктора, настолки итд, которая впоследствии может производиться в России и обладать соответствующим культурным или научным колоритом. Было подано что-то около 22 тысяч идей, я отправил две. В следующий тур вышло несколько сотен, в том числе внезапно одна из моих — заводная подводная лодка, которая плывет не вперед, как существующие заводные игрушки для ванны, а прям погружается и всплывает. Связал я это не с военными подлодками, а с научными глубоководными аппаратами, по которым у России несколько мировых рекордов. Вы знали, например, что Кэмерон брал наши глубоководные «Мир-1/2» для съемок Титаника? А еще они первыми достигли дна Северного Ледовитого Океана.
После отбора вы попадали в этап моделирования, где нужно было сделать 3D-модель, чертежи, спецификацию, описание и так далее. Здесь я уже не обошелся без помощи профессиональных 2D и 3D художников. Заказал эскизы и моделирование внешнего вида, а сам уже в Компасе дорабатывал нужные элементы для сборки.
Моделирование отсекло ещё значимый процент участников, где-то 70-80 человек в пяти категориях вышли на этап создания прототипа. И вот тут я скажу вам, сложно передать, сколько хитрых инженерных задач пришлось решить по пути. Проект оказался одним из самых сложных (и одним из самых интересных) в моей практике. Вообще, айтишнику полезно поработать с материальным миром, изобилующим погрешностями и допущениями.
Герметичность корпуса, например, испытывает противоположные воздействия при движении в среде вверх и вниз — швы, не пропускающие при погружении, начинают пропускать при всплытии. Разница в два грамма балласта на таких масштабах влияет на плавучесть очень значительно, поэтому балласт должен легко регулироваться (я остановился на двух отсеках с ружейной дробью). Мультипликатор заводного механизма пришлось перепроектировать пять раз, попутно печатая фотополимером зубчатые колеса с модулем пол миллиметра. Сделать фотополимер цветным с устойчивостью к воде — офигенно непростая задача с не самым очевидным решением: в жидкий раствор с нужным базовым оттенком подмешивается пигмент для эпоксидных смол, и только потом печатается на чуть увеличенной засветке. Сделать полностью прозрачное стекло не вышло, но и текущая частичная прозрачность получилась не сразу. Даже у жетонов был десяток итераций, чтобы они не оказались слишком тяжелыми, и чтобы металлическое ядро для захвата магнитом не было слишком далеко от стенок. Добавьте сюда подбор шага и размеров винта, сложности работы с моделью такой формы, летнюю жару, из-за которой постоянно забивался подающий механизм принтера...
Но результатом очень доволен, смотрите видео. Прямо сейчас еду в Москву на выставку игрушек, где выберут победителей, чьи проекты запустят в тираж уже на настоящем производстве.

IELTS BAND8.5+ #Schedule
✅A - READING!
Make sure that you spend at least 1 hour a day on the following (don’t forget to record vocab, underline useful collocations, copy them into your vocab book... if you have one):
✅ B - WATCHING
Don't watch your content passively with the video/radio etc. playing in the background. You need to listen attentively since you'll need to do the same in the exam. Train your ear at an early stage and make life easier for yourself down the line. Oh, and if watching something.... subtitles OFF! 1 hour a day, too.
📆 MONDAY
📖National Geographic: select THEMES and randomly read an article whether science, travel, adventure, animals etc.
💻Documentary: think about what you might have read and type the theme into YouTube
📆 TUESDAY
📖Time Magazine: click the box top left next to TIME and randomly read an article whether politics, business, tech, health etc.
💻YouTube Videos: I have put together a number of YouTube channels I enjoy in a post.
📆WEDNESDAY
📖 The Guardian: Randomly select different themes and select an article at random to read
💻BBC World service is a good one. Loads of different themes for background listening: https://www.bbc.co.uk/sounds/play/live:bbc_world_serv..
📆THURSDAY
📖Scientific American : randomly select a news article to read.
💻 Documentary: Curiosity Stream is a good one, but it's a paid website.
📆FRIDAY (Entertainment)
📖 Continue reading a book of your choice PROVIDING it’s not a classic (continue with that after your course)
💻 Watch a film of your choice but still have pen and paper ready! Subtitles off!!!
📆SATURDAYS AND SUNDAYS
Focus on doing your grammar and vocab exercises, practice tests as well as go over the vocab and things you have recorded during the week. Use the weekend to write your essays.
My guidelines:
📌 It doesn't matter if you're interested in the themes or not. In the exam you don't have a choice. So stop being selective. Move beyond Friends and The Big Bang Theory.
📌 Record "chunks of language". Once you've done the article or video, summarize it out aloud recycling that language you have just jotted down. Maybe even write a small summary.
📌 Less is more! Do one article or video a day. That's enough. Better do one, learn and recycle the language rather than watch/read too many and remember nothing.

On any platform, when we want to do something #asynchronously, it usually involves an #event loop. An event loop is a loop that can register #tasks to be executed, execute them, delay or even cancel them and handle different events related to these operations. Generally, we #schedule multiple async functions to the event loop. The loop runs one function, while that function waits for #IO, it pauses it and runs another. When the first function completes IO, it is resumed. Thus two or more functions can #co_operatively run together. This the main goal of an event loop.
