• Is there considerable energy saving using a black background on my website?

  - by isolatedIterator

  I had heard that you can save power by using a black background instead of a coloured background. Is there any evidence that this saves power on people's monitors? Is this a way that we can cut down on energy consumption (millions of users times milli-watts add up over time). It could also affect battery life on mobile devices.

• PostgreSQL or MS SQL Server?

  - by mmiika

  I'm considering using PostgreSQL with a .Net web app. Basically 3 reasons: Mature Geo Queries Small footprint + Linux Price I'm wondering a bit about tools though, SQL Server Profiler and query plans and performance monitors have been helpful. How is this world with Postgres? Some other things I should consider? Edit: Will most likely use NHibernate as ORM

• Running server-program from a .jar file

  - by skiwi

  I have created and am working on a server-application that monitors for specific folders and takes appropriate actions whenever files are being added. Now I come to the point where I want to be able to shutdown the program, for example for applying a patch. The server runs simply in a command prompt, how can I signal that I want to perform maintenance on it? I do not think reading System.In is feasible as I am also outputting text in the prompt. Regards.

• Did anyone manage to make katmouse work over vs 2010

  - by Silviu

  As you might know katmouse enables scrolling over non active windows. Which would be especially great in vs 2010 because now you can take source code windows to other monitors. But of course it does not work. Is there a trick to make WPF receive the right message?

• Twitter Bootstrap Navbar blocking svg viewBox

  - by user1167650

  I have a navbar fixed to the bottom and I have page that has a title and a giant svg (created by d3.js). I would like the svg to take up the entire screen (whatever is left over), but it always seems to have some part appear behind the bottom nav bar. I've tried: 1) using viewBox to auto-resize, setting the parent div and the svg to be block elements 2) adding padding-bottom to the body element But the svg still appears behind the navbar on wide screen monitors.

• How to use JavaScript to measure how bright a users monitor is ?

  - by HankV

  I've noticed that the brightness of computer monitors drastically varies between computers. As such, this changes the look of web pages greatly. Is there a way to use JavaScript to automatically detect how bright (or dark) a users monitor is so that I can adjust my web page colors accordingly? UPDATE Please note that I do not want manual user involvement. I want this detection to be automatic so that users don't realize I dynamically change the color palette automatically based on the brightness/darkness of their monitor.

• Fade unfocused GNU Emacs frame (X window)

  - by Mischa Arefiev

  Is it possible to make GNU Emacs 24 dim unfocused windows a bit? For example, I can set my rxvt-unicode clients to become darker when their windows don't have focus with this string in ~/.Xdefaults: URxvt*fading: 50 It greatly reduces discomfort when you have a lot of terminal windows on 2+ monitors. I would like a similar feature in Emacs, but couldn't google up anything. Here is how it looks like with urxvt (png, 1.43 MB)

• Overriding SetThreadExecutionState

  - by unixman83

  I am not sure if this belongs on serverfault or superuser. I would like to override SetThreadExecutionState(ES_DISPLAY_REQUIRED) to be a no-op. How is this accomplished? Is there some registry setting that can be altered instead of API hooking? Blocking ES_DISPLAY_REQUIRED will prevent apps from keeping the monitor powered on. I have an application (likely the antivirus) that is preventing some monitors from entering power-save and I think this function is the culprit.

• vb.net how to check for changes in folder upon application start?

  - by Luay

  while the application is running i'm using FileSystemWatcher to monitor the folder. But what if there are changes to the folder when the application is not running, how can I check for these changes when the application starts. (similar to how windows media player, for example, monitors your music folder. Even when you add songs to that folder when it is not running, it does discover them when it runs next time) Thanks

• How to obtain the correct physical size of the monitor?

  - by KindDragon

  How can I get the size of the display in centimeters or inches? This code does not always works correctly: HDC hdc = CreateDC(_T("DISPLAY"),dd.DeviceName,NULL,NULL); int width = GetDeviceCaps(hdc, HORZSIZE); int height = GetDeviceCaps(hdc, VERTSIZE); ReleaseDC(0, hdc) Especially for multi-monitor configuration. Update: I need to get the size just for ordinary monitors, which have a constant physical size.
