Quite a while, my top posting was about waste at the government. Now something more positive on waste, and other lean subjects: I recently read the book 'Een lean overheid'. The book is in Dutch, and gives a nice introduction on using Lean in government organizations.
Unlike other lean books, translated to Dutch or not, it's written specifically for the Dutch government. I guess most of this information is relevant for Dutch speaking readers, for those that speak English only: I am very fond of using lean at the government. Some people at the UK government seems to be getting it, as well as the US government. Hopefully the government in the Netherlands catches up soon!
Inspired by an OS that went in oblivion some years ago (BeOS) operating systems as Windows, Linux and MacOS all have ways to monitor directories for changes built into the filesystem: meaning if a directory is changed because a file or directory is added, removed or changed you can get an event. There's need for running a program that periodically monitors the directory (nor does the OS do that, it's build into the filesystem). Software like Dropbox and other filesyncing products use this, so whenever you change or update a file it's immediately updated to the 'cloud'.
The name of the API's for the listed OS's are:
- On Windows, the ReadDirectoryChangesW function as part of the filesystem API.
- On Linux, the inotify can be used.
- On MacOS, there's FSEvent api (source arstechnica).
There are a number of open source libraries that allow you to use that API in Java, not all cross-platform. Fortunately, since Java 7 watching directories is now part of the default java.nio.file API.
