I am trying to build a simplified EA from 'top to bottom', what I mean is I have a large diagram which has multiple objects, mainly ERDs Entities. I also have more and more detailed diagrams and can successfully drill down by hyperlinking to the next level down.
I have even setup a hyperlink on each of the lower level diagrams to go back to the previous.
So far, so good. When I publish as HTML, I get a really useful web tree that pretty much does what I want, except for one thing!
Each of the lower diagrams are reasonably small, so when I drill back up, I am happy with being positioned at the top left of the previous diagram (with me so far?).
When I drill back up to the primary diagram, I get returned to the top left.
BUT - as this primary diagram prints out on 12 A3 pages, it would be really good to be able to return to the area of the primary diagram that refers to the diagram that I just clicked into/out-of.
I am no deep HTML expert, but I know there is methods in HTML to hyperlink to a specific part of a page. Can anyone think of a way to tweak the returning hyperlink to position me at a specific point in the primary diagram?
PHEW
Thanks, PGB
To my knowledge there is no way to achieve this using EA's hyperlinks. EA does not use HTML internally, and an EA diagram hyperlink has no space for offset or zoom level, it simply opens the diagram.
Normally I would say that if you want an element to do something like this you can code it up yourself in an Add-In, but I'm pretty sure you can't specify pan/zoom when opening a diagram in the API either.
So I'm afraid this is one of those rare occasions where the answer is "you're doing it wrong." Adding all information everywhere is a sure-fire way of ending up with a model that's both impossible to navigate and a nightmare to maintain.
To build a better model you should work with abstractions and/or aspects (hard to say which is the better route forward without doing an actual architectural analysis).
What I do is to create sub-domain diagrams and then drag those onto an overview diagram. They scale down to nearly iconic size but still give an idea of the contents. Now I use large text to explain those sub-domains. This can usually fit to some A3-size (A2 if you like to show off). But from this overview you can easily focus to the single sub-domains by double-clicking the diagram frames.

I've been trying different tiling WM's to see which one best fits my needs. Every time I try a new one, it looks good but I find other things that don't quite work the way I like. My requirements have evolved as I go. Initially, I didn't want to get into Awesome because having to learn Lua is not on my wish list but maybe I should give it a try IF it can do what I want better than the other tiling WM's out there.
I'm going to as specific as I can about what I want. I am running a 3440x1440 monitor. I want to use as much vertical space as possible (meaning, a full width, persistent but mostly empty status bar is not an option, but I do like the notification area and a date/time).
I understand it may not do everything exactly the way I want, which is oke. If it does more or less most of what I want I can weigh my options between Awesome and other tiling WM's (actually, only i3 which is what I'm using now but I'm open to better suggestions). I would very much appreciate it if people don't just say no to something it can't do, but say "no, but it can do ...". In other words, feel free to suggest alternatives that might be helpful as well.
Divide the screen in 3 columns, initially 30/45/25, with the right column split horizontally; Fully adjustable and resizable as needed during my work session;
Persistent layout; when closing the last application in a tile, I don't want that tile to disappear and the remaining tiles to resize. Just show an empty space and leave all tiles as they are.
tabbed tiles, so I see which applications are running in a tile (similar to i3).
Resizable tiles with the keyboard into 1 direction; When making the middle column/tile wider, I want that into a specific direction into another tile and leave the other side alone.
Certain applications I want to always launch into a specific tile. For instance, terminals always go into the right-most column top/bottom, browser/spotify always into the middle, atom/IDE always into the left. Some applications should always be floating. Obviously I want to be able to send them to a different tile after launch.
I don't want a 100% width status bar. It will be mostly empty which is a waste of screen estate. Preferably, I'd like a statusbar part of a tile, for example in the right-most tile, resizing with it. Otherwise I'd like it to be fixed to 30% and allow tiles which are not beneath it to use the full height of the screen. My reason for a statusbar is mute; I actually only want a notification area and a date time permanently visible. I don't need a "start menu", dmenu or similar is perfect, which I believe it has integrated.
Many thanks in advance!
The general answer is "Awesome configuration is code and it can do whatever you want". But there is a catch. Can Awesome be configured like you describe? Yes, totally. There is at least 2 distributions coming close enough (mine[1] and worron[2]) (at least for the tiling workflow, not the look).
The "catch" is that the workflow you describe isn't really the "Awesome way". Awesome is usually used as an automatic tiler. You have layouts that describe a workflow (code, web, internet) and manage the clients according to their programming. Manual tile management is rarely necessary once you have proper layouts. That doesn't mean you can't, I did, but it might be worth thinking outside the box and see if you can automate your workflow a bit further.
Also, the default layout system isn't very modern and makes it hard to implement the features you requested. My layout system (see link below) can be used as a module or as a branch and supports all features described above. Awesome is extremely configurable and it's components can be replaced by modules.
https://github.com/awesomeWM/awesome/pull/644
The layout "serialization" documentation is here:
https://elv13.github.io/libraries/awful.layout.html#awful.layout.suit.dynamic.manual
It is similar to i3 but has more layouts and containers. As for the "leaving blank space" part, it is configured using the fill_strategy:
https://awesomewm.org/doc/api/classes/wibox.layout.ratio.html#wibox.layout.ratio.inner_fill_strategy
As a word of conclusion, I would note that what you ask is "work exactly like i3". If you want such thing, well, use i3. Awesome is a window manager framework. Its goal and purpose is to create a customized desktop shell / WM. If it's what you want, then go ahead and learn it, nothing else can come close to the possibility and the level of control you can get out of it. However it takes time and effort to get to the point where you have "your own perfect desktop". Our users perfect desktops:

The WM your are looking for is herbstluftwm (hlwm). Its a manual tiling window manager. The tiles which you are talking about are called frames in hlwm. Each frame can contain multiple windows. A frame can also be empty. Only if you kill a frame the other frames will automatically resize. You can add new frames vertically and horizontally and resize them. Each frame can also have a different layout to organize the windows inside. The layout you are looking for is max. This will stack the windows inside a frame on each other. It doesn't show you tabs like i3 however. hlwm allows you to create rules to open certain applications always in certain frames and workspaces. hlwm doesn't have a statusbar buildin. I personally like to use tint2. It can be used as a replacement for your requirement to see running applications as tabs.
I'd like to use a more sophisticated graphics or GUI widget library in my Hammerspoon config file, in order to get user input and do more advanced drawing on the screen than Hammerspoon allows (as far as I can tell) by default. I'm new to Lua and Hammerspoon, and so far I've been unable to figure out how to get this working. (Simple drawing on-screen is not a problem, so examples of geometric shapes are not helpful. I can do that already with no difficulty.)
I initially thought one of the Lua libraries designed for building games would have more than I could possibly need, and looked into love2d, but it did not appear to be possible to use with Hammerspoon in any straightforward manner.
To give two concrete examples of things I'd like to do:
I'd like to display a dialog box in which the user can enter two values, to specify how many rows and how many columns they want in their screen grid. A native Cocoa dialog would be better, but something graphically drawn on screen with Lua would be fine, as long as the details of the image are abstracted away for me, and I can just define the text and fields and buttons in the dialog.
I'd like to draw a dotted-line rectangle with curved corners and a shadow around specified grid segments as a preview of where a window would be moved if the user completed a certain command.
There's a lot more, but anything that allows me to do those things should allow me to do anything else I want.
We don't yet have a good answer to generating dialog boxes, although it is possible to do it with AppleScript, which you can call from Hammerspoon with hs.osascript.
As for drawing things like dotted-line rectangles, we can't currently do that, but if you'd like to file an issue on our GitHub project, it's something we can look at for a future release :)
I'm trying to figure out the best way to procedurally animate the growing of a 2D plant in iOS.
I want the plant to animate to give an encroaching feeling to the user.
Basically, to animate the growing of a branch, with little buds that will eventually animate into full grown leaves.
To breathe a little life into it, I'd also like the plant to sway a bit as it grows, rather than feeling hand painted on the screen.
One way I've thought of is to use CGPaths and Bezier curves to create the shape of the stalk and the leaves, but I'm not entirely sure how to animate the drawing of the paths. Once I get the "drawing" of the stalk, i'd like to "plant" little buds at certain points on the stalk, as the line is growing/animating and these buds will also start to grow outwards from the plant.
Any suggestions on what route to take to accomplish this task? I'd prefer to procedurally animate as opposed to hand drawing each frame and animating that way. My reasoning is that I imagine procedurally animating will be less time consuming, give me more control over different aspects of the animation, and be reusable in other projects (not to mention, it will be fun to program!)
I've come across this blog posting for the drawing of animated lines:
http://oleb.net/blog/2010/12/animating-drawing-of-cgpath-with-cashapelayer/
Perhaps this would be a starting approach for achieving the results I want, I need to sit down and go through the code he posted.
Also, maybe this is something that would be easier to do using cocos2d or something similar? Or perhaps quartzcore and core animation will work fine.
Thanks for any suggestions you might have, any information is helpful at this point.
(Great question! Posting this as a "community wiki" since it is not an answer but just some references and I didn't want the links to get screwed up in comments. Perhaps people want to add to this?)
I did a simple search on "procedural tree branching code" and there were lots of interesting hits - really rich area.
A post on gameDev.stackExhange pointed to this great resource: Algorithmic Botany
Also Snappy Tree is pretty amazing and the source code is available.
These two also sound interesting:
TReal is a program capable of generating realistic 3D tree models.
Arbaro is an implementation of the tree generating algorithm described in Jason Weber & Joseph Penn: "Creation and Rendering of Realistic Trees" written in Java.
Perhaps more accessible to the OP and with a less complex result are these actionScript tutorials on fractal trees. ActionScript drawing code is pretty easily translated to Core Graphics.
I have a broad but interesting OpenCV question and I'm wondering where to start.
I am looking for any strategies or white papers that might help.
I need to get the position of people sitting at a conference table from a fixed overhead view. Ideally, I will assign a persistent ID to each person, and maintain a list of people with ID and coordinates. This problem could be easy in a specific case - for example, if designed for a single conference room table - but it gets harder in the general case, especially with people entering and leaving the scene.
My first question: is it a detection or a motion tracking problem? Or some combination of the two?
Well it seems like both to me. I would think you would need to take a long average of the visible area which becomes the background. Then based on your background information you can track movement of other objects.
Assigning an ID may become difficult if objects merge together (at least as far as the camera is concerned) and then separate again, say someone removing a hat placing it down and placing it back on.
But all that in mind it is possible even if it presents a challenge. I once saw a similar project tracking people in a train station using a similar approach (it was in a lecture so I can't provide a link sorry)
I need to find graphic editor, which can create simple swimming pools drawing like this: http://k.min.us/iiPZI.png
It must be able to draw pool outline (including curves, not only lines), split pool into several parts (the darker color is - the deaper poll is in this area), also user should be able to provide depth for each area.
Also will be nice, if this editor can calculate pool square (S), perimeter (P), it's scope (V) and square of all walls and bottom (to know how much tile we`ll need).
Please, give me links to any editors, which contain even several of these functionalities, so I can try and upgrade editor for my needs.
You can give links on editors, written on any language/platform (Javascript, standalone programm, etc.). I will need to calculate all this staff (V, P, S, etc.) and then just send this data to PHP (and make calculations on server side).
I found only this editor, but it doesn't have a lot of functionality I need: http://svg-edit.googlecode.com/svn/branches/2.5.1/editor/svg-editor.html
I guess any good vector editor might do but not sure about the calculations. This might be more a job for an architecture program. You might want to take a look at Inkscape
