 Welcome to this week's update on the J-Wiki group. I'm Bob Terrio and I come to you from the unceded territories of the Qualicum and Comox First Nations and we thank them for the use of their lands. Now this last week we had a meeting about the J-Wiki and one of the things that became apparent was there's so much information in the current Wiki that people don't even know about. So this week I'm going to dive into some of that information and you're going to find a little bit more about that. In the future we're going to be reorganizing the Wiki so some of this information is more readily available but for now we thought it was important that you just get a sense of what's in there so that you can explore yourself. So here we are on the main page of the J-Wiki and you can see it's divided into sort of sections. Sections are very useful but honestly you rarely see the main page because there's actually not very many links to it. So instead of what we've done to make it a little bit more accessible is down the side here on the sidebar we've put some of the more useful links. I've gone through some of them before but let's just take a look at some of the ones that I think people may be aware of but they may not be aware of the depth of things. So starting off with NuVoc. This is NuVoc. You're probably familiar if you've been working around J with the primitives and the discussions you can get the monadic or the dyadic versions. Lots of information but something that people don't know quite that much about or maybe they don't explore quite as much. These are all the control words. Are these ancillary pages? The ancillary pages are really useful. Specifically look at this one called Start Here. Click here and it gives you a great rundown on how to really use NuVoc and there is a lot of information here especially with monad and dyads, structure of primitive pages, the ancillary pages and then where you go beyond NuVoc. So really useful information there. If you haven't looked at how to use NuVoc before go to NuVoc down to the ancillary pages and take a look at that. Now next thing is on beyond NuVoc. Let's click on that and that takes us to some of the things like the essays. Now people often when they're giving links to J often get linked to an essay. Some really deep information, lots of code, lots of well thought out stuff. Really useful but if you just get a link to it you don't really know where it sits or what else is there. So let's go back up to here and if you want to find essays you go to Showcase and under Showcase there's essays. So I click on essays and this is part of some problem that we're trying to overcome. Look at all these essays. I mean it's excellent that there's that many of them but you know and the titles sometimes are useful. I mean if you're looking at combinations, it'd be a good idea to look at you know combination index or combination sums or combinations. You know tensors there's stuff there. There's a lot of information there but it's just so much of it and we're going to be working on sort of reorganizing some of this to make a little bit more accessible. More about that probably next week but right now this is where essays are. Take a look at these they're just fascinating. I mean there's great very deep information here if you want to go deeper into how to program in J. This is a master's level exploration of J. So let's go back again to oh wow you're going to showcase here. So back to Showcase here the other thing to explore here is books and specifically I'm going to talk about two books. Some of these other ones that you might have heard of before are some of the labs and explorations when you're learning but Eugene McDonald had done a lot of essays for Vector and in fact he did 41 articles for Vector called At Play with J and they're all really excellent. Really good way to look at a deeper look at some of the tricks that you can do with J and just some explorations of some interesting ideas. Now 50 Shades of J was done by Norman Thompson. Norman's original essays again were done for Vector and they were called J Oddings or Jottings. That was his pun but they all were put together into 50 Shades of J and made into a book or in this case the wiki has a collection of wiki pages and these are I would say probably more conceptual, more to think about sort of the background on how things are done whereas Eugene might take a specific problem and work it through. Norman is taking a slightly different more comprehensive look at how to do some of this stuff and they're really excellent. You click here you can get access to it. They're all the chapters and he's got language philosophy chapters, aesthetics, all sorts of things that you may have wondered about with J and on the side here this was all sort of compiled and brought up to date by the community so if you see a green check it means this person, Rick Sherlock in this case, has gone through it and made sure that it runs on the current versions of J. If you see a red check it's possible that it's not entirely done in this case it looks like it needs a test but in any case you can still look at it and there's still information there and so that's 50 Shades of J and at play with J both excellent resources. Finally let's take a look back up here and I'm going to go to guides because a lot of times when you're working with J you're working with frameworks or you're working with interfaces and you think how does anybody keep any of this straight? Well if you go to guides again it's a link on the sidebar you can obviously have things for the beginners here that's ways to get into J. The user interfaces really use all information here depending on the user interfaces you're using frameworks this is how the labs are put together JD which is the JD database gives you lots of information if you're ever wondering about plot this is a great place to find out more about plot or publish and I haven't worked much with publish but I guess there's an equal amount of information there about publish also technologies and in general all these different again long list of things that you can find out more about running J notebooks in Jupyter things like this if you don't know about this go in take a look at guide especially if you're trying to find out about something and you just don't know really where to start sometimes it'll be sitting there in guide with the new wiki we will be taking information like J602 that might be out of date and we'll be putting it into an archive so it's still available but it's not going to be maybe up as in the way as some of the other information is so that's guides new walk and in showcase essays and books and by all means go and explore them there are tons of information there's so much in in this wiki about J right now it's not the easiest thing to find but these are the places to explore and as you get more comfortable with it you may find other places that are really worth exploring in it I think that's about it this week until next week enjoy your explorations with Jay and happy array programming
