This is Kevin Haddock + +00:00:02.800 --> 00:00:05.839 +to announce the introduction of N-Angulator, + +00:00:05.839 --> 00:00:07.759 +hereafter called NA. + +00:07.759 --> 00:00:10.240 +NA allows you, the user, to supply + +00:00:10.240 --> 00:00:11.679 +the meaning to your data + +00:00:11.679 --> 00:00:13.599 +in a concise, efficient way. + +00:00:13.599 --> 00:00:14.880 +How does it work? + +00:14.880 --> 00:00:16.880 +Your files are stored on your hard disk + +00:00:16.880 --> 00:00:18.160 +in what technically is called + +00:00:18.160 --> 00:00:20.640 +a hierarchical file system. + +00:20.640 --> 00:00:22.240 +What this means is that + +00:00:22.240 --> 00:00:24.560 +the root of the directory tree can be + +00:00:24.560 --> 00:00:27.760 +not only files, or what we call leaves, + +00:00:27.760 --> 00:00:30.720 +but also other folders/branches + +00:00:30.720 --> 00:00:33.680 +that themselves contain other files, leaves, + +00:00:33.680 --> 00:00:36.000 +and/or branches. + +00:36.000 --> 00:00:37.680 +This structure is supposed to + +00:00:37.680 --> 00:00:40.079 +make it easy to locate your data, + +00:00:40.079 --> 00:00:42.079 +but as anyone knows who has worked with this + +00:00:42.079 --> 00:00:43.600 +single-dimensional file system + +00:00:43.600 --> 00:00:45.280 +for any length of time, + +00:45.280 --> 00:00:46.800 +it can get quite frustrating + +00:00:46.800 --> 00:00:48.960 +when your file would fit equally well + +00:00:48.960 --> 00:00:52.079 +on more than one branch of the tree. + +00:52.079 --> 00:00:53.920 +What are you to do? + +00:53.920 --> 00:00:55.920 +Create multiple copies everywhere + +00:00:55.920 --> 00:00:57.840 +it might appropriately fit. + +00:00:57.840 --> 00:00:59.039 +What if the file was something + +00:00:59.039 --> 00:01:01.120 +people would occasionally modify, + +00:01:01.120 --> 00:01:04.879 +like a spreadsheet or a computer source file? + +01:04.879 --> 00:01:07.760 +You would have to hunt it down in every place + +00:01:07.760 --> 00:01:11.840 +and apply those changes everywhere by hand. + +01:11.840 --> 00:01:14.720 +Also, let's say not only did you want + +00:01:14.720 --> 00:01:17.040 +to put the file in multiple places, + +00:01:17.040 --> 00:01:18.799 +but it was also more appropriate + +00:01:18.799 --> 00:01:21.280 +to give it different names? + +01:21.280 --> 00:01:23.280 +Plus, let's say in different areas + +00:01:23.280 --> 00:01:25.119 +of the tree, there were files + +00:01:25.119 --> 00:01:26.560 +with the same name + +01:26.560 --> 00:01:29.280 +that had totally different content? + +01:29.280 --> 00:01:31.280 +Then updating all the different instances + +00:01:31.280 --> 00:01:32.640 +of the file you need + +00:01:32.640 --> 00:01:35.200 +would become more and more of a nightmare. + +01:35.200 --> 00:01:37.920 +In addition, wouldn't it be great + +00:01:37.920 --> 00:01:39.520 +if we could all speed up + +00:01:39.520 --> 00:01:42.479 +the actual searching for a particular file + +01:42.479 --> 00:01:45.680 +by selecting multiple branches in the tree + +00:01:45.680 --> 00:01:47.200 +and simply asking the computer + +00:01:47.200 --> 00:01:49.680 +to tell us which branches under those + +01:49.680 --> 00:01:52.560 +contain the same file and which do not? + +01:52.560 --> 00:01:54.000 +This would be especially great + +00:01:54.000 --> 00:01:56.719 +if it were instantaneous. + +01:56.719 --> 00:01:58.640 +Well, believe it or not, this is what NA + +01:58.640 --> 00:02:00.079 +brings to the table. + +02:00.079 --> 00:02:03.040 +In fact, this is how NA got its name. + +02:03.040 --> 00:02:05.040 +Your data is located by a process + +00:02:05.040 --> 00:02:06.960 +very similar to the triangulation + +00:02:06.960 --> 00:02:09.119 +used to locate radio signals, + +00:02:09.119 --> 00:02:10.160 +only we are not limited + +00:02:10.160 --> 00:02:12.000 +to just two or three angles, + +00:02:12.000 --> 00:02:14.720 +but instead, many dozens can be used, + +02:14.720 --> 00:02:16.879 +this makes NA appear to be + +00:02:16.879 --> 00:02:18.640 +what is known in computer lingo + +00:02:18.640 --> 00:02:21.760 +as an n-dimensional sparse array. + +02:21.760 --> 00:02:23.599 +If that sounds complex, don't worry. + +00:02:23.599 --> 00:02:25.280 +It will become clear when you see it + +00:02:25.280 --> 00:02:28.720 +in operation in a couple of minutes. + +02:28.720 --> 00:02:32.560 +To start out, here we see the NA main screen. + +02:32.560 --> 00:02:36.080 +There are two vital aspects of mastering NA. + +00:02:36.080 --> 00:02:37.760 +First is the actual mechanics + +00:02:37.760 --> 00:02:39.120 +of using the program, + +00:02:39.120 --> 00:02:40.480 +which should be second nature + +00:02:40.480 --> 00:02:41.920 +for most anyone familiar with + +02:41.920 --> 00:02:46.160 +either a Windows or Unix/apple file system. + +02:46.160 --> 00:02:48.080 +We have the same operations + +00:02:48.080 --> 00:02:50.400 +as one might do with Windows Explorer + +02:50.400 --> 00:02:52.560 +or any number of other file tools, + +00:02:52.560 --> 00:02:54.560 +but what we also do + +00:02:54.560 --> 00:02:56.080 +that generally they do not + +00:02:56.080 --> 00:02:58.000 +is place a leaf on a branch, + +00:02:58.000 --> 00:03:00.560 +then cruise around adding links to that leaf + +03:00.560 --> 00:03:02.720 +on a multitude of other branches, + +00:03:02.720 --> 00:03:05.120 +which could include creating, renaming, + +00:03:05.120 --> 00:03:07.360 +or restructuring more branches on the fly + +03:07.360 --> 00:03:10.480 +as needed. Plus, when we find ourselves + +00:03:10.480 --> 00:03:12.319 +hunting for that file, + +00:03:12.319 --> 00:03:13.840 +we can incrementally select + +00:03:13.840 --> 00:03:15.120 +a stack of branches + +00:03:15.120 --> 00:03:17.200 +while seeking what the latter branches + +00:03:17.200 --> 00:03:19.920 +have in common with the earlier ones, + +03:19.920 --> 00:03:22.720 +to make putting one's finger on exactly + +00:03:22.720 --> 00:03:26.239 +the item they're looking for a snap. + +03:26.239 --> 00:03:28.319 +Secondly, you have the actual art + +00:03:28.319 --> 00:03:29.680 +of organizing your data, + +00:03:29.680 --> 00:03:31.120 +and NA doesn't really put + +00:03:31.120 --> 00:03:32.640 +any limitations on this, + +00:03:32.640 --> 00:03:34.799 +other than the underlying limitations + +00:03:34.799 --> 00:03:36.560 +of the file system. + +03:36.560 --> 00:03:39.760 +Let's get started, shall we? + +03:39.760 --> 00:03:41.920 +Right-clicking the mouse button here + +03:41.920 --> 00:03:43.760 +will bring up what we call + +00:03:43.760 --> 00:03:46.000 +a branch navigation menu, + +00:03:46.000 --> 00:03:46.959 +because it allows you + +00:03:46.959 --> 00:03:48.239 +to move around the tree + +00:03:48.239 --> 00:03:50.159 +or commence a new angle. + +03:50.159 --> 00:03:52.480 +We have chosen to organize our data + +00:03:52.480 --> 00:03:55.519 +with a hopper to put new items in, + +00:03:55.519 --> 00:03:57.360 +and the initial branches representing + +00:03:57.360 --> 00:03:59.519 +who, what, where, why, and how. + +00:03:59.519 --> 00:04:01.280 +We right-click on the root + +00:04:01.280 --> 00:04:03.439 +and select 0hopper, + +04:03.439 --> 00:04:06.000 +and that branch is added to the display. + +04:06.000 --> 00:04:08.080 +If we middle-click on the branch, + +04:08.080 --> 00:04:09.360 +we get what is called + +00:04:09.360 --> 00:04:11.280 +the branch command menu, + +00:04:11.280 --> 00:04:12.959 +which gives us many options, + +00:04:12.959 --> 00:04:13.920 +not the least of which + +00:04:13.920 --> 00:04:15.920 +is to create a leaf here. + +04:15.920 --> 00:04:18.000 +Remember this item as we progress, + +04:18.000 --> 00:04:20.320 +because it will become important. + +04:20.320 --> 00:04:22.960 +Next we pick what we know is a leaf item, + +04:22.960 --> 00:04:24.720 +due to the fact that it does not have + +00:04:24.720 --> 00:04:30.960 +a trailing slash. + +04:30.960 --> 00:04:32.960 +Now, when we right-click on it, + +04:32.960 --> 00:04:35.040 +notice the navigation menu is limited to + +00:04:35.040 --> 00:04:37.040 +the two items: New Angle + +00:04:37.040 --> 00:04:40.960 +and the leaf name itself. + +04:40.960 --> 00:04:43.680 +If we want to view or edit that leaf item, + +00:04:43.680 --> 00:04:45.440 +we can select that item. + +04:45.440 --> 00:04:47.280 +Now that we have selected a leaf, + +00:04:47.280 --> 00:04:48.560 +let's middle-click on it + +00:04:48.560 --> 00:04:49.520 +to bring up what we call + +00:04:49.520 --> 00:04:51.600 +the leaf command menu. + +04:51.600 --> 00:04:54.080 +This shows us a bunch of standard options + +00:04:54.080 --> 00:04:56.160 +one might do in a typical file tool + +00:04:56.160 --> 00:04:58.320 +like Microsoft Explorer. + +04:58.320 --> 00:05:00.479 +Since we want to do what they cannot do, + +05:00.479 --> 00:05:01.680 +let's right-click the leaf + +00:05:01.680 --> 00:05:04.639 +and select New Angle. + +05:04.639 --> 00:05:06.400 +Notice that another slash has appeared + +00:05:06.400 --> 00:05:09.840 +below the displayed path of the leaf. + +05:09.840 --> 00:05:11.520 +Right-click on it, and you will see + +00:05:11.520 --> 00:05:14.639 +the root branch navigation menu appears again, + +05:14.639 --> 00:05:19.039 +but now 0hopper entry has a line + +00:05:19.039 --> 00:05:20.960 +both above and below it. + +05:20.960 --> 00:05:23.199 +Items in between these two lines + +00:05:23.199 --> 00:05:24.560 +are called members, + +00:05:24.560 --> 00:05:27.520 +and items below them are called others. + +05:27.520 --> 00:05:29.680 +What this is saying is that + +00:05:29.680 --> 00:05:32.160 +the previously selected angle, + +05:32.160 --> 00:05:34.160 +which can be a single leaf + +05:34.160 --> 00:05:35.840 +as in this instance, + +05:35.840 --> 00:05:37.360 +or can be all of the leaves + +00:05:37.360 --> 00:05:38.960 +under a particular branch + +00:05:38.960 --> 00:05:43.039 +chosen to navigate new angle from, + +05:43.039 --> 00:05:44.880 +shares content with the items + +00:05:44.880 --> 00:05:47.680 +under the member area of the menu, + +00:05:47.680 --> 00:05:50.880 +but items in the others area do not. + +05:50.880 --> 00:05:53.600 +Since the first angle is 0hopper, + +05:53.600 --> 00:05:56.800 +of course it shares content with itself, + +05:56.800 --> 00:05:59.199 +and so it appears in members. + +05:59.199 --> 00:06:01.199 +Now let's click the middle button + +00:06:01.199 --> 00:06:02.960 +on the root branch, and see what + +00:06:02.960 --> 00:06:07.360 +the branch command menu has to say. + +06:07.360 --> 00:06:09.280 +Notice that the entry that used to say + +06:09.280 --> 00:06:13.120 +Create a New Leaf now says Add a Link. + +06:13.120 --> 00:06:15.039 +This is because we have already selected + +06:15.039 --> 00:06:17.360 +a leaf, and now we want to add links + +00:06:17.360 --> 00:06:20.479 +to it rather than create a new one. + +06:20.479 --> 00:06:21.840 +If you go back to the root + +00:06:21.840 --> 00:06:24.319 +and reselect 0hopper, + +06:24.319 --> 00:06:29.039 +that option will revert back again. + +06:29.039 --> 00:06:40.880 +So let's add a link under person. + +06:40.880 --> 00:06:42.720 +We right-click the root, + +00:06:42.720 --> 00:06:46.720 +select person, and let's add a link. + +06:46.720 --> 00:06:50.560 +Notice the bottom area (called the minibuffer) + +00:06:50.560 --> 00:06:53.360 +gives us the proposed name of the link, + +06:53.360 --> 00:06:55.680 +and we choose to accept it by hitting enter, + +00:06:55.680 --> 00:07:09.759 +or edit it to taste first. + +07:09.759 --> 00:07:10.960 +Now let's go back up to + +00:07:10.960 --> 00:07:13.120 +the end of the prior angle, + +07:13.120 --> 00:07:15.360 +select New Angle again, + +07:15.360 --> 00:07:18.319 +and then click the resultant /, + +00:07:18.319 --> 00:07:20.240 +and see what are members + +00:07:20.240 --> 00:07:21.840 +and what are others. + +07:21.840 --> 00:07:24.319 +Notice that the 0hopper and person + +07:24.319 --> 00:07:25.759 +are members. + +07:25.759 --> 00:07:28.319 +NA knows you added content to the person, + +00:07:28.319 --> 00:07:32.160 +so it moves to members. + +07:32.160 --> 00:07:33.599 +Now let's add some more links + +00:07:33.599 --> 00:07:35.360 +and perhaps a few subdirectories + +00:07:35.360 --> 00:08:06.960 +for this item. + +08:06.960 --> 00:08:08.960 +Notice how we can even eliminate + +00:08:08.960 --> 00:08:11.039 +the file name extension. + +08:11.039 --> 00:08:13.680 +It will still know how to display the item + +00:08:13.680 --> 00:08:15.440 +as it actually analyzes the file + +00:08:15.440 --> 00:08:17.120 +to determine its type. + +08:17.120 --> 00:08:19.120 +This greatly cleans up your metadata + +00:08:19.120 --> 00:08:40.719 +and makes it more human. + +08:40.719 --> 00:08:41.839 +Now let's pick a branch + +00:08:41.839 --> 00:08:43.519 +from one of the menus. + +08:43.519 --> 00:08:44.880 +For instance, let's look and see + +00:08:44.880 --> 00:08:54.880 +where any events broadcast were done from. + +08:54.880 --> 00:09:06.640 +We select event, broadcast, then New Angle, + +09:06.640 --> 00:09:09.600 +and we can see California is in members. + +09:09.600 --> 00:09:11.600 +Now we can also do New Angle + +00:09:11.600 --> 00:09:13.920 +and select person, + +09:13.920 --> 00:09:16.160 +and we can see who did them. + +09:16.160 --> 00:09:18.720 +Another thing we can do is pick a leaf + +09:18.720 --> 00:09:19.920 +and quickly display + +00:09:19.920 --> 00:09:21.920 +all angles or links for it, + +00:09:21.920 --> 00:09:24.160 +or if we are willing to wait a little longer, + +00:09:24.160 --> 00:09:26.720 +have NA construct all the display items + +00:09:26.720 --> 00:09:28.320 +with Edit All Angles, + +00:09:28.320 --> 00:09:30.160 +so we can manipulate them + +00:09:30.160 --> 00:09:31.440 +just as if we had entered + +00:09:31.440 --> 00:09:44.320 +or selected them by hand. + +09:44.320 --> 00:09:46.080 +There are many more tools in NA + +00:09:46.080 --> 00:09:47.440 +to handle sets of leaves + +00:09:47.440 --> 00:09:50.320 +such as scanned pages of a book, + +09:50.320 --> 00:09:53.040 +promoting /, demoting nodes, + +09:53.040 --> 00:09:54.560 +and so forth. + +09:54.560 --> 00:09:55.560 +Thanks for watching. + +00:09:55.560 --> 00:09:58.040 +[captions by sachac] |
