I have been looking at a few labs (again and again) and they are still in a very strange stage.
I think they are vital part of J and I think it is a mistake to have most of them in a very uncertain condition and not warn eventual/potential new users about them better than what is done now. They give a very bad impression when failing all over the place. For me personally they seem to be improving even though ever so slowly and there are very interesting and exciting things happening. The JHS and GTK are so far away from each other that it is obvious that there are not much interest in making efforts to make them work together. They look and feel different. I can see benefits of having them share folders but they are also a cause for confusion when trying to execute in one something intended for the other and causing failures. As I said earlier then when choosing a lab there should be an indication in what stage it is and if it is tested/finished and working in that particular environment. I am very pleased with the workings of grid as well as the graphichs in GTK I am also very pleased with many things in JHS that are improving as time goes by. Marketing and informing users is not a major interest for many people involved in J and amazing things happen if you keep digging. 2011/10/18 Björn Helgason <[email protected]> > Executing the turtle in JHS and taking the line load'graphics/jturtle/ from > the GTK part will give you an interesting problem further on. > > After this step: > ── ((1) 5 of 40) The session window ─ > > The turtle seeimbly hangs forever: > > At this stage it is important that the JHS server is not hidden because > there are a number of errors reported there: > > > > (jconsole.exe:3892): GLib-GObject-CRITICAL **: gtype.c:2708: You forgot to > call > g_type_init() > > (jconsole.exe:3892): GLib-CRITICAL **: g_once_init_leave: assertion > `initializat > ion_value != 0' failed > > Probably because trying to call on GTK services > > So it may not be a good idea to have the same labs for both JHS and GTK > unless there being a test for the environment. > > Probably better to have two separate sets of JHS and GTK labs as well as > different sets of demos. > > After all the GTK and JHS are vastly different > > > 2011/10/18 Björn Helgason <[email protected]> > >> I can not figure out why advancing the labs in JHS is sometimes ESC A and >> sometimes ctrl +. >> >> >> 2011/10/18 Björn Helgason <[email protected]> >> >>> To show an example about the confusion about the labs here is one: >>> >>> >>> Turtle lab >>> in GTK I get the line >>> load 'graphics/jturtle' >>> >>> In JHS I get the line >>> load 'turtle' >>> and then execution fails >>> not found: C:\j701/turtle >>> >>> JHS seems to be using lab from addons/labs/labs/general >>> >>> GTK is using lab from addons/graphics/jturtle >>> >>> The testing page lists addons/labs/labs for the turtle >>> >>> Running the lab in each starts and looks the same but then the JHS labs >>> fails >>> >>> >>> 2011/10/18 Björn Helgason <[email protected]> >>> >>>> I have always been a great fan of labs. >>>> >>>> In the J6 labs/demos are absolutely great. >>>> >>>> In J7 there is somewhat of a confusion about how to feel about labs and >>>> demos. >>>> >>>> I have mixed feelings what to say or do about labs and demos in J7. >>>> >>>> I looked at the page you refer to and I think it is a god beginning. >>>> >>>> I counted the entries on the page and counted 49 labs >>>> >>>> On the JHS labs choosing page I counted 77 labs >>>> >>>> In the GTK labs selection I counted 83 labs >>>> >>>> In the labs selection the full names are a bit different between JHS and >>>> GTK >>>> >>>> I would like to see the same name in both and I would also like to see >>>> the columns from the test page of the status of the lab if it is fully >>>> tested and working or if it is still under some kind of transfer problem >>>> and >>>> then I mean where I am choosing the lab in JHS and GTK to make life for the >>>> user/tester/developer easier. >>>> >>>> The labs and demos are very important part of learning J and I think >>>> they are very important to make J7 better and easier to use. >>>> >>>> >>>> 2011/10/18 Ian Clark <[email protected]> >>>> >>>>> > It is interesting to try out the labs in both GTK and JHS. >>>>> >>>>> And while you're at it, please remember to record your results at: >>>>> http://www.jsoftware.com/jwiki/Addons/labs/labs/ControlLabs >>>>> >>>>> (Work has stalled since May.
