I reported several message about the lab descrepancies without any response.
The wiki reports a few labs to work on but only a few. The GTK reports a certain number - different from JHS and Wiki. I find it a weaknesss that I tested several there who gave an error message that the files were not there in GTK. That possibility remains into the future and I think it is really bad. Once you understand how JHS goes about reporting labs it really finds you will appreciate it and it stimulates more people to write more labs and that is really very good because it is so easy. Take any lab change it a little bit and use save as and give the new file a new name and after starting JHS server the lab you created is there and ready to be used. In GTK you would have to do more changes and also in the Wiki. The less administration you need the better and it stimulates growth. The JHS and GTK are so very different anyway so who cares about this small difference. Having J open source and more people working on individual parts then the less administration you need the better. If you want to reorganize the lab system it is easy in JHS you just decide what folders to scan and move ijt files into them and it is done. Moving files around in the lab system in GTK part calls for all kinds of fixes and same goes for the Wiki and it is not good if you make a typo or if you move a file and in the admin file the information change does not reflect the change so all in all I prefer the JHS way of handling the labs. 2011/11/29 Ian Clark <[email protected]> > Both are capable of being fixed -- even if it's only to give helpful > error messages. > > Why don't JHS and JGTK use the same method of updating & finding their > labs?
