Make only the arrowheads larger in Gephi Overview Section? - gephi

I have a very dense network. In order to see the directionality of the arrow, I have to zoom in really deep. I cannot increase the width of the arrows too much since the graph becomes too cluttered. Is there some way I can increase just the arrowhead size without affecting its width?
I am aware of a setting in the Preview tab under the "Edge Arrows" section that lets me control this. But is there a way to do this setting in the Overview tab as well?
Thank you for your time.

Seeking advice on best way to build a graphic Control

I am trying to build a custom control which can draw the outline and pins of an integrated circuit.
At present I am using 2 frames, one holding a panel which will represent the package outline. THis frame will be place on a form. The other frame will represent a pin which will contain a shape to represent the pin and two labels, one for pin number one for pin description. My plan is to create the pins dynamically according to package aspect ratio and number of pins.
Are frames a good basis for this or are there better alternatives.
A frame is a good starting point but is heavy. Probably the best solution is to build a custom control. As ancestor, you could start either with TGraphicControl or TWinControl depending on the features you need. Read the documentation to select the best fit for your case.
TCustomControl which derive from TWinControl is a good ancestor for controls that wrap Windows screen objects but perform their own rendering.
The documentation I linked above gives examples of controls.

Before diving in, is this possible with Awesome WM?

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.

SPSS 21 - creating better graphs

SPSS' default settings for graphs are pretty rudimentary and, generally, ugly.
I have just upgraded from v.12 to v.21 and am very surprised, and extremely disappointed, to see that there is practically no change.
I had high hopes for GPL, but it does not seem to offer anything more than basic settings.
For instance, I want to create a sequence of scatterplots.
The dimension should be 375 points square.
Both axes should go to 1,000.
The points should be size 1, colour dark red.
The chart background should be white.
I also want to create a sequence of scatterplots.
The dimension should be 375 points square.
X axis should go to 1,000,
Y axis to 160.
There should be 50 bins - (x-axis, number of intervals).
Display digit grouping should be on.
Histogram bar fill and border should be colour a and colour b (these will vary, but should be scripted).
Finally, a set of box plots which also need customisation away from the default settings.
So, is it possible to script customisations like this, or do I have to go through the VERY SLOW and TEDIOUS point and click process for every one?
I HAVE 105 GRAPHS!
Thanks for your advice.
GPL provides syntax control for all of these things. The graphics engine in V21 is entirely different and much more flexible than the ancient on in V12.
The Chart Builder UI offers only basic, general controls. There is a huge amount of functionality in GPL that is not exposed in the CB. Paste the syntax from that as a starting point, and look at the GPL documentation in the help. You may also want to create a template with your specifications and use that from the CB as a shortcut.
The GraphBoard editor provides another interface ultimately to the same graphics engine. It offers more aesthetic control but is harder to customize.

Creating "performance" output bars in iOS - Photoshop/programming interplay

My partner and I are trying to figure out how best to create scaling, colored performance bars for one of our mobile exam-prep apps. The goal is to create a horizontal bar that graphically represents a scale of 0 - 100% using Photoshop or something similar. We had hired a professional graphics designer but we're left holding the bag trying to figure out how to make the graphics actually "fill the bar" in the actual app.
(I can't post pictures yet, but you can see a link to the picture here):
http://www.productionplanningpro.com/wp-content/uploads/2012/06/Screen-Shot-2012-06-25-at-9.47.24-PM.png
As the bar would reach certain percentages, it would change color from Red to Green appropriately. I'm trying to figure out how to give this to my contractor without handing him 100 files, each showing 1% more of the bar (and even then, I'm not a graphics artist, so this whole thing is above my head). I've done as much research as I can stand, and I've seen the fancy iOS graphing APIs - we're just looking to fill in these two bars.
Any insight or help is SUPER appreciated!! Thanks!

There are quite a few solutions to this problem. I'm sure there's a way to fill in the area with that shadow programmatically, and I'm also sure someone will come along with a masking solution sooner or later.
The quickest and easiest way, though, is to have your artist simply create that red filler bar one time, and have it fill the entire space (ie. drawn at 100%). Then you make sure that, in the graphic that is the 'outside' of the bar, the space where the red bar should be is an alpha channel.
When you actually get to coding it, place the red bar at the very bottom of all the objects you're drawing to the screen. The rest of your UI should entirely hide it. Then as progress moves from 0% to 100%, you move the bar slowly to the right, filling in the space (and showing through the alpha hole in the 'bar holder'.
Quick, simple, have done this many times before. Masking would work as well, but seems a bit overkill in your situation (and I don't have any experience with it on iOS, so I can't offer any assistance there!) Let me know if you have any questions while trying to implement this :)

Do I still need to pad images in a CSS Sprite?

In CSS Sprites you will often find padding between each image. I believe the idea is so that if the page is resized then one image won't bleed into another.
I think this depends on the different types of browser zoom (best explained by Jeff).
However, I haven't been able to see this behaviour in my tests. Is this only a problem with older browsers? (I havent been able to test with IE6 at the current time so I'm counting that as 'old').
Should I still worry about leaving space? Its kind of a pain.
For instance :
A CSS Sprite I found for AOL has
padding between each image : VIEW
but The Daily Show decided not to
bother : VIEW
It shouldn't need to be padded, but when zoomed, especially in IE8 (betas more than the RC), there is image bleeding if there is no padding.
Best example is to go to Google.com -> Search, and zoom... you'll start to see "underlines" at the bottom right of the image as the zooming rounds up/down.
In theory, a 1px padding on all sides of a sprite should be fine.
Here's the sprite from Google (images)...
But when zoomed, the +,-,x icons bleed into the main Google logo.
Basically the answer is yes. Two years to the day after I asked this question will see the release of IE9. IE9 has this problem just as much - if not more than any other browser...
It's pretty infuriating because it's such a simple thing to fix.
With iPads increasing in marketshare - its's pretty essential to at least have a half decent experience with zooming un-uniform amounts.
I am going to have to put a single pixel border around every image to match the background color of the adjacent element (potentially different on each side). Fortunately I auto-generate all my csssprites based on an .xml file - so I can do this programatically without too much hastle. It's still a huge pain though...
Simon - My experience is that this is certainly still a problem.
In response to your second question, why not use transparent padding? (Perhaps you are still supporting ie6 and this is non-trivial, in which case, I'm really sorry).
Speaking of the older browsers (those using text zoom), you don't always need padding.
The main difference between your two examples is that the Daily Show sprite already includes the menu item's text in the image itself.
When using text zoom, the AOL menu items could stretch out vertically due to the larger font size, and the menu text might even wrap to two lines. To accommodate for such eventualities, those icons need a little padding to ensure they don't bleed. Typically, you'd just try to make sure it doesn't bleed on any of IE6's five text sizes.
Since The Daily Show's menu doesn't contain any (visible) HTML text its size won't be affected by text zoom (though you might need a line-height: 0; or so to be sure), so it doesn't need any padding.
As scunliffe already showed, browsers using page zoom may need sprites to have a little padding due to rounding errors.
