The standard names for indexes in PostgreSQL are:

{tablename}_{columnname(s)}_{suffix}

where the suffix is one of the following:

• pkey for a Primary Key constraint;
• key for a Unique constraint;
• excl for an Exclusion constraint;
• idx for any other kind of index;

*  This loop loops through a collection called `collection_name`
*  and sorts it by the front matter variable `date` and than filters
*  the collection with `reverse` in reverse order
*
*  To make it work you first have to assign the data to a new string
*  called `sorted`.

• На iOS устройствах числовые значения подчёркиваются синим. Эта проблема возникает из-за того, что iOS устройства по умолчанию считают все числа похожие на телефонные номера - телефонными номерами. Решается добавлением <meta name="format-detection" content="telephone=no" /> Тоже самое касается адреса: <meta name="format-detection" content="address=no" />

• Пользователь может уменьшать и увеличивать приложение. Решается добавляением тега <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />

• Ссылки нажимаются с задержкой (примерно 300ms). Решается подпиской на событие touchstart и принудительной инициализацией события click после него. Если проблема всё равно возникает - ничего не поделать, надо облегчать dom. Как вариант - можно использовать библиотеку, посоветанную @adubovsky ниже в комментариях: https://gist.github.com/SerafimArts/de9900f99

How to add environment variables to nginx.conf

This is the hack approach to adding environment variables to the nginx configuration files. As with most Google results for this search, the reason is Docker.

The setup

I intended to deploy two Docker containers.

Rectifier

The diode bridge is the simplest rectifier I know.

Rectifier lets you share a directory with a docker container (just like $yourvm shared folders).

You don't have to install anything in your containers, and you only need to install diod in the host. diod is packaged on Ubuntu/Debian distros, and will automatically be apt-get install-ed if needed.

Since it uses diod to make a bridge, I called it rectifier. Yeah, that sucks, so if you have a better name, I'll steal it!
