Pay attention and do not use it improperly. The is_admin() function is NOT to check is the current user is an administrator! I saw this error many times and probably I did it myself years ago. The is_admin() function provided by WordPress as core function is not to check if the current user is an […]
Is it possible to dynamically “disable” a plugin with a condition determined by some visitor attributes? Like the presence of a cookie? Of course without changing the plugin code!

WordPress fires and activation action when a plugin is activated. Or at least it should. To be notified of its activation, a plugin can register itself to that even, using the register_activation_hook() function. There are some background concept that must be clear before start to use that action. It is not always as natural as […]
You may need to add some tLogRow components in your Talend job to monitor during test the ETL progress, but then you need to turn them off when you run the job in production. Probably you have already at least two contexts: the one you use in the test environment and the one to be […]

The Apache Camel cMQTT component stores the topic component as an additional message header named CamelMQTTSubscribeTopic. Hence inside […]
Installing the Talend Runtime as a service is rather easy but there are few options you would consider to customize even more the installation. This has been tested with version 7.2.1. First you can follow the instructions directly from the Talend Help Center to create the wrapper. A wrapper is a Windows executable which “wraps” […]
When you build a route a new .kar file is generated and it needs to be redeployed on Talend ESB container. Nothing special to do, just copy it on deploy folder.
