I want to calculate the scale factor for my current window in WxWidgets.Can anyone help me with this?
Do you mean wxWindow::GetContentScaleFactor() or something else? If so, you'd need to explain what...

Like in the title. Can be anything, python script or whatever. Also I need to measure time of the playback and/or average framerate. Thanks in advance
I wanted to solve the following equation in Anylogic:
0=44.00*m^6+7.84*m^4-43.2*m^3+7.84*m^2+1.16
Anylogic have a lot of Numeric tools. Can somebody help me how to use this tools?

You could use an online calculator to solve it, e.g. Symbolab, which will also detail the steps, which may give you sufficient information to construct a solution in AnyLogic.
It solves it thus.
I want to do HDR capture based on HAL3, but i have two problem now.
Problem 1: We know that HDR need to snapshot three image. It can be realized by sending three capture requests, but i don't think it's a good idea. So do you know how to solve this problem?
Problem 2: The HDR need different exposure time to the three image, one image must take a short exposure time, one image must take a middle exposure time and the last one must take a long exposure time. I want to know how to achieve this effect.
If you have some experience in android camera in HAL3, or you have some example code, can you tell me? I am in troble in this for a long time. Thank you very much!
How can I detect sound on the iPhone?
I currently have it somewhat working using the method described in this article http://mobileorchard.com/tutorial-detecting-when-a-user-blows-into-the-mic/
However, as mentioned in that article, in noisy rooms for example, the method won't work.
So in a way, I'm looking for methods that I can use to separate background noise from actual noise intended?
There probably won't be an existing code on the internet, but if someone can point me to the right direction, it would be very appreciated.
Thank you,
Tee
It's definitely not a great solution, but you could determine a baseline amplitude (ambient sound) and trigger your events when you determine that the amplitude is a certain amount greater for a set amount of time.
Sorry I know the question isnt as specific as it could be. I am currently working on a replenishment forecasting system for a clothing company (dont ask why it's in VBA). The module I am currently working on is distribution forecasts down to a size level. The idea is that the planners can forecast the number to sell, then can specify a ratio between the sizes.
In order to make the interface a bit nicer I was going to give them 4 options; Assess trend, manual entry, Poisson and Normal. The last two is where I am having an issue. Given a mean and SD I'd like to drop in a ratio (preferably as %s) between the different sizes. The number of the sizes can vary from 1 to ~30 so its going to need to be a calculation.
If anyone could point me towards a method I'd be etenaly greatfull - likewise if you have suggestions for a better method.
Cheers
For the sake of anyone searching this, whilst only a temporary solution I used probability mass functions to get ratios this allowed the user to modify the mean and SD and thus skew the curve as they wished. I could then use the ratios for my calculations. Poisson also worked with this method but turned out to be a slightly stupid idea in terms of choice.
