Роскосмос пару дней назад опубликовал отчёт о том, почему упала "Луна-25". Там конечно канцелярит, но можно примерно понять, что двигатель коррекции получил неверные данные от акселерометра:
из-за возможного попадания в один массив данных команд с различными приоритетами их исполнения прибором
Это очень похоже на программную ошибку, а это моя сфера, и я решил над ситуацией поразмыслить.
Хейтеры сразу стали строчить комментарии в стиле "Ололо, наняли каких-то идиотов, которые простейшие тесты не провели". Тут обычно справедливо вспоминают аварию с европейской ракетой Ариан-5 в 1996 году. Там буквально из-за пары строчек кода в результате неправильного приведения числовых типов ракета за 7 млрд баксов развалилась на куски в воздухе. Бывает.
Что касается Роскосмоса, при всей его сомнительной репутации, объяснение "Дураки не провели тесты" звучит лично для меня неправдоподобно. На мой личный взгляд возможны два варианта:
1. Если в описании ошибки слово "приоритет" обозначает какой-то признак внутри объекта команды, значит, на входе в приёмный модуль эти команды не были отфильтрованы. Выглядит как грубая ошибка, целый логический блок упущен. Вряд ли этот блок вообще не написан, скорее всего он не выполнился. Такое бывает, если в тестовой среде есть какое-то условие, которого нет в рабочей, и именно это условие отвечает за выполнение участка кода.
Сталкивался с таким миллион раз. Самое дикое из последнего: код парсит эксель-таблицу с числами. Разработчик написал, запустил проверил, прогнал тесты, всё ок. Отправляем в прод — все числа будто бы рандомно меняются на другие. Запускаем снова — у всех разработчиков функционирует нормально, а в проде на сервере нет. Таблица одна и та же. Можете подумать, почему так. Ответ: у разработчиков стоит русская локаль и десятичный разделитесь это запятая, а на проде в докере точка. При парсинге на проде запятая уже интерпретируется как разделитель тысячных разрядов.
2. Куда вероятнее, что слово "приоритет" в описании ошибки обозначает время, а, значит, список команд просто не был отсортирован, и в обработчик уже после актуальных значений попали какие-нибудь начальные нулевые данные, сбившие логику. По косвенному описанию проблемы очень похоже именно на это. Значит, на тестах всегда порядок возникновения команд соответствовал порядку их прихода, а в реальности перестал соответствовать. Вообще, работать с железом очень сложно. Какую-нибудь схемку заглючило от холода, она задержала ответ от датчика на миллисекунду, и всё. Никто не знал, что такая проблема возможна, пока она не возникла.
Мне рассказывали о таком случае: юзер логинится на сайт и иногда логин проходит, а иногда нет. Логин и пароль те же самые. Просто в случайные моменты времени ему возвращают токен авторизации, а в другие моменты времени ошибку 403. Никакой закономерности нет вообще. Нет зависимости от времени суток и даты. Сервер точно работает стабильно и не падает все 100% времени. Почему так может быть? Ответ: у сервиса авторизации два инстанса, перед которыми балансировщик нагрузки. В одном инстансе данные для авторизации есть, в другом нет. Балансировщик при примерно одинаковой нагрузке включает просто случайный выбор между ними.
В общем, программисты иногда допускают такие косяки, что какая-то мелочь может привести к серьёзной аварии. Это я вам говорю как программист, который пишет для атомных станций :)

📣 Pump result : The pump didn't go as we expected, and for that, we deeply regret any disappointment caused to our community. This time our efforts led to a peak of 100% profit. While this is a positive result, it's not up to the high standards we set for ourselves and for you. We encountered an "iceberg" coin, presenting us with unexpected and relentless sell orders, which significantly impacted our strategy.
In addition, we faced external challenges with large on-chain OTC transactions to kucoin accounts creating sell walls below our targets, quickly affecting the coin's momentum. We chose this coin based on its potential for a potential ATH breakout, doing so would've lured thousands of traders to trade the dips alongside our community, aiming to maximize your profits. Unfortunately, this decision didn't yield the results we expected. Our team has tried to keep the price up but was unsuccessful due to the nature of this coin. We invite everyone to take a look at the daily chart to understand more our reasoning behind this pick. Our team had the pure intention of boosting the price up to at least 2000% in this pump for all our members but unfortunately it was impossible on this coin.
In the next pump we will make sure we pick a coin that we know for sure can be pumped to more than 1000%+ and our team will make sure that we will reach that target once again by injecting a massive amount of USDT during the pump after our members had bought already. Our whales will use our own capital to push a coin similar to the mega pump which took place on #QUICK, with that being said we expect another 1000%+ profit signal. Today was a one off result, the amount of factors which could've gone into play today were immeasurable and we apologize once again for the lack of foresight. Next pump we will absolutely make sure that we pick a coin we have experience in and that can definitely be pumped to a high price without facing any issue. Stay tuned for our next announcement!
Pump result : One of the best pumps we have had lately! The volume was around 2 million $ with a peak of almost 1500% exactly 6 minutes after the signal was given which is very impressive. The signal on #QUICK was announced and the price started to steadily rise 400%, and with the help of our whales and our big influence the price managed to climb to a whopping 1500% just a few minutes later meaning that everyone that had bought within the first 7 minutes made a massive amount of profits. There were several waves to profit from during the pump, and we're glad to hear so many of you managed to earn alot today.
#QUICK is still sitting at over 500% over an hour later, we promised you guys a special pump to end this year off and we did exactly that! Our signals will keep getting better because our community is growing massively! With our current calculations we are expecting at least 100k new members by the start of the next pump which we will try to surpass a 2000% profit target. Our power is starting to get uncontrollably huge and we thank you guys for trusting us all this time, we appreciate each and everyone of you and hope you and will continue to do what we do best. Stay tuned for the next one as it is going to be even bigger. Our team will make sure to deliver the biggest pumps we have ever seen starting in 2024. Happy holidays everyone.
💥HOW TO WIN YOUR CRUSH 💥
Part 4
📌 Be flirtatious
One of the easiest ways to let him know you’re interested is by flirting. Though this may not be the initial approach you want to take in your texts, once you feel comfortable flirting with him, make sure you do so in a fun, exciting way—without giving away your feelings too much.
The trick is to not make him think that you’re crazy about him, because you don’t want to overwhelm him or make him feel
smothered. Finding the right balance will have him feeling excited to talk to you and curious about your feelings for him. He’ll also be impressed by your confidence.
An easy way to flirt with someone without coming off too strong is by teasing them. Again, be careful not to take this overboard or he may start to consider you as “one of the guys”. Use winking emoticons and make cute innuendos to let him know that you’re excited to see him or to hint that things may get hot and steamy
when you do.
#Quick Tip: If you already have a texting relationship, sending a sweet text saying, “Hope you’re having a great day!” or, “Thinking of you :)” will cheer him up and keep you on his mind. Since most guys have a positive reaction to the word “great” it’s a helpful word to use. More on this later.
