Systemwidgets has died. All attempts at resurrecting the previous content from backup have failed.
TextFileSplitter is now being hosted over at http://www.datakido.com/downloads
The splitting engine and console application code has been released at GitHub: https://github.com/Datakido/TextFileSplitter
I will try to get as much as possible moved over at http://www.datakido.com This includes articles, but mostly other downloads.
