This is a sample of how to send some information to logstash via the TCP input in nodejs or python. It assumes the logstash host is on 10.10.10.100 and the TCP listening input is 9563.

The logstash.conf should look something like the sample file.

The log message should be a stringified JSON object with the log message in the @message field.

To use, run the node script node sendMessageToLogstash.js, or the python script python sendMessageToLogstash.js

Translation Mechanism in Magento 2.x Platform

This article discusses the translation mechanism in Magento 2.x, and contrasts it with that of Magento 1.x. The intended audience is Magento developers who would like to better learn the Magento architecture.

The Magento 2.x source code described here has been available since Magento 2.0.0.0-dev46 release and can be viewed on the GitHub at https://github.com/magento/magento2/commit/0849373d7636cfa17b70b8188bfc36d13ae749c1 or later commits.

Implementation Overview in Magento 1.x

Magento 1.x can present the user interface in different languages without modifying the actual application source code—it translates the system messages, error messages, and labels for display in the UI. Some messages may be displayed in logs for a system administrator or a developer—those don't need to be translated. By convention, in the source code, the labels and system messages for UI are expressed in English (en_US).

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
