Unspecific Dataflow Import error in Magento
xml,magento,csv,import,dataflow
It turns out that the error was written in plain html. After copying it into a .html file and opening it in a browser a complete back-end Magento page popped up, stating that a module license was not valid (due to creating a staging area). After disabling the module, importing...
Run Magento 1.9.1.0 Dataflow Import Profile Programmatically
php,xml,magento,import,dataflow
After much frustration, here's the answer that works: Note that in this case I've configured the default Magento Dataflow Profile for Import All Products (ID: 3) to read in an XML import format, from a predefined file. This is a file I create as needed prior to running the import...
TPL Dataflow block consumes all available memory
c#,.net,task-parallel-library,dataflow,tpl-dataflow
You seem to misunderstand how TPL Dataflow works. BoundedCapacity limits the amount of items you can post into a block.

Cyclic IObservable Chain in Reactive .NET
c#,.net,system.reactive,reactive-programming,dataflow
The line Bar(fizzes, buzzes).Subscribe(f => fizzes.OnNext(f)); can be made simpler and changed to Bar(fizzes, buzzes).Subscribe(fizzes); as the Subscribe method takes an IObserver, the lambda methods that are normally used are just shortcuts for this. As such, fizzes is being used as an IObserver and an IObservable, which is the definition...
