//Flowing LED Lights
/* Eight LEDs will light up one by one from left to right, and then go out one by one from right to left.
After that, the LEDs will light up one by one from right to left, and then go out one by one from left to right.
This process will repeat indefinitely.*/

Обновление SSL-сертификатов LetsEncrypt для MS Exchange (autodiscover и webmail)

Добавить комментарий

1. Через certbot выпустить сертификаты letsencrypt:

$ sudo certbot certonly --manual -d webmail.mydomain.ru --agree-tos --manual-public-ip-logging-ok --preferred-challenges dns-01
$ sudo certbot certonly --manual -d autodiscover.mydomain.ru --agree-tos --manual-public-ip-logging-ok --preferred-challenges dns-01

Для подтверждения домена редактировать записи DNS на хостинге. Проверять, что DNS-записи обновились, через любой Linux:

$ dig _acme-challenge.autodiscover.mydomain.ru txt @8.8.8.8

2. Забрать готовые сертификаты fullchain.pem* и ключи privkey.pem* из папки /etc/letsencrypt/archive/
3. Сделать из файлов .pem сертификаты .pfx через программу openssl:

>"C:\Program Files\OpenSSL-Win64\bin\openssl.exe" pkcs12 -inkey privkey3.pem -in fullchain3.pem -export -out autodicover_20190417.pfx

4. Загрузить в MS Exchange сертификаты .pfx («Import Exchange Certificate...»)

5. Выбрать для чего использовать сертификаты (Assign Services to Certificate):
webmail — IMAP, POP, SMTP, IIS
autodiscover — SMTP

Установка плагинов Python вручную без pip

1 комментарий

1. Скачать плагин с сайта https://pypi.org/project/
2. Распаковать
3. Выполнить что-то вроде

C:\Users\user\Downloads\py\pyodbc-4.0.23.tar\dist\pyodbc-4.0.23\pyodbc-4.0.23> C:\Users\user\AppData\Local\Programs\Python\Python36\python.exe C:\Users\user\Downloads\py\pyodbc-4.0.23.tar\dist\pyodbc-4.0.23\pyodbc-4.0.23\setup.py install

Если для плагина все зависимости удовлетворены (например установлены другие плагины или компилятор Visual Studio и т.д.), то плагин успешно установится

C# как узнать, какая вкладка открыта в tabControl

Добавить комментарий

this.tabControl1.SelectedTab – сама выбранная вкладка

this.tabControl1.SelectedTab.Text – её заголовок

tabControl1.SelectTab(1); — выбрать вкладку по номеру
