Мвп это не про переписывание с нуля каждой новой итерации, а про обрастание жиром со временем

Как консалтинг вообще происходит?

Я не догоняю досихпор. Вот у вас нет по вебу серьезных человек, вы такие нанимаете сеньера на пару месяцев, он вам кодит, и уходит?

в моем понимании скорее так

есть стартап, который до этого был на уровне "из говна и палок нахуячить МВП" - гипотеза оказалась денежной, подняли дохуя бабла инвестиций - как их лучше всего потратить (особенно учитывая рынок, убегающий от тебя к конкруентам)? нанимается челик на короткий период со "сверх компетенциями" (по крайней мере его так продают) который их передает, закладывает технические основы (архитектуры, инфраструктуры, процессов и тд) будущего продукта с определенными требованиями (производительность, красивость, способность гдето быть гибким) и определенным будущим (большая масштабируемость, поддержка и развитие "более заурядными" проггерами).

 

Архитектуру и стэк закладывают до мвп.

лол

мвп это почти что прототип

потом это всё переписывается к хуям

потому что на этапе мвп не понятно что нужно и как и делается все "lean" тоесть поминимуму

не исключаю что большое количество сервисов развивают то что сделали на этапе мвп, просто потому что этого достаточно

но уж точно до мвп не прорабатывают архитектуру будущего продукта который смасштабирован до уровня миллионов пользователей

Что-то у тебя плохо с мат. частью. Закладывают в начале, плюс в эпоху клауда это всё делается на раз-два.

ну там вообще гениальное форматирование текста и название переменных. Особенное однолайнеры нравятся с entity++.

[suez]

Конкретно в этом случае от "консалтинга" лишь тот факт что материнская компания называется Boston Consulting Group. Он с коллегами работает в подразделении, которое пилит мвп стартапов для больших компаний, называется Digital Ventures. И вот он с частью команды куда-то высаживается и что-то пилит с нуля полгода+ и потом идет на следующий проект. Скорее всего они и "настоящим" консалтингом может быть занимаются, но конкретно сейчас они вот в Сингапуре заняты доведением стартапа до беты, после чего они все свалят (в конце января).

а, ну BCG, это многое объясняет :)

Как минимум говно то что для всех этих 320 кейсов нет перечисления.

Человек сам как эту хуету читает?

Гайс, а подскажите, тут был парень - профессор или что-то такое, в питон для веба врывался. как у него дела, дропнул уже или еще не?

Привет! Народ, кто может помочь с кодом? Делов на 5 минут. Я плохо ориентируюсь. Язык Python. У меня есть код с гитхаба, нужно из него взять несколько блоков и соединить. Весь код переделывать не надо.

Что нужно:

 

1. Создаётся колода.

2. Раздаются карты игрокам и на стол.

3. Считаются комбинации игроков.

4. Комбинации сравниваются и выбирается победитель/и.

5. Данные выводятся в консоль.

 

Пример:
Board: 5c 6d Ac 4h 2h
Player 1: 5h Ad
Player 2: Kc Kh
Player 3: Qd Jс
Player 4: 10s 9c
Player 5: 8s Jh
Player 6: 2d 3h

Win: Player 6
Win: Straight - 2h 3h 4h 5c 6d 

 

Если победителей несколько, то список идёт вниз по порядку.

 

Я уже спрашивал на популярных сайтах по кодингу, но там молчат. Я сам бы мог, но просто у меня на это уйдет недели две. Помогите пожалуйста, кому нетрудно.

Привет! Народ, кто может помочь с кодом? Делов на 5 минут. Я плохо ориентируюсь. Язык Python. У меня есть код с гитхаба, нужно из него взять несколько блоков и соединить. Весь код переделывать не надо.

Что нужно:

 

1. Создаётся колода.

2. Раздаются карты игрокам и на стол.

3. Считаются комбинации игроков.

4. Комбинации сравниваются и выбирается победитель/и.

5. Данные выводятся в консоль.

 

Пример:
Board: 5c 6d Ac 4h 2h
Player 1: 5h Ad
Player 2: Kc Kh
Player 3: Qd Jс
Player 4: 10s 9c
Player 5: 8s Jh
Player 6: 2d 3h

Win: Player 6
Win: Straight - 2h 3h 4h 5c 6d 

 

Если победителей несколько, то список идёт вниз по порядку.

 

Я уже спрашивал на популярных сайтах по кодингу, но там молчат. Я сам бы мог, но просто у меня на это уйдет недели две. Помогите пожалуйста, кому нетрудно.

Привет! Народ, кто может помочь с кодом? Делов на 5 минут. Я плохо ориентируюсь. Язык Python. У меня есть код с гитхаба, нужно из него взять несколько блоков и соединить. Весь код переделывать не надо.

почему у тебя весь код в одном файлике?
разбей на разные файлы по логическим состовляющим(погугли mvc pattern) создай репозиторий, запуш на гитхаб, потом вернись и попроси помощи еще раз.

[yellyex]

Да блин. Код тот уже не нужен. Я бросил копипастить и пытаюсь сам разобраться.

Почему у меня карта не показывается?

import random

class Card():

    def __init__(self, rank, suit):
        self.rank = rank
        self.suit = suit

    def showCard(self):
        print(rank, suit)

card = Card
card.showCard(1, 1)

Ошибка.

Кто-нибудь может мне на коленке колоду карт сделать? У меня 40 примеров с гитхаба, все разные, и я хуй знает, что и как там написано. Можете по-детски код колоды карт написать? Я хотя-бы точку отправки получу. Спасибо.
