How can I generate the NES palette entirely in C# code, without using any constant values?
I want to precalculate the palette in the same way that the PPU does.
Thanks!
You can simulate the chip based on the YPbPr signals the NES sents, but just make it easy for yourself and pre-program the colors using the hex values from wikipedia or some other source.

I need to get the value of a single pixel of the screen at a predetermined location, in something like hex or rgb and it should be quite fast. How can i do that in Go?
Rosetta Code has a page with solutions for this problem in various languages, including Go.
https://rosettacode.org/wiki/Color_of_a_screen_pixel
Using the RobotGo library you can call GetPixelColor to get the color of a screen pixel as a hex string.
RobotGo supports Mac, Windows, and Linux(X11); and robotgo supports arm64 and x86-amd64.
I want to design a 3D human hand and control it via signal generated from my Arduino kit. I designed a 3D hand in Blender but how to give the signal generated from Arduino to add life into it. Which tool I should use.
For example I have designed an arbitrary frequency generator. And I want at a particular frequency the Hand will mimic Pinching, or to Fist. Which tool I can use to use the generated signal as input to a Programming interface and output of the Program as a Animated 3D hand.
Please help guys......
Thanks in Advance.
Python would seem the obvious solution to this, as it can interface directly with Blender.
I'm not sure how your controller works with frequencies, but chances are there's a library or a way to handle it in python.
I would suggest looking at this forum post to learn how to set up the animation you want via python script.
Python can then be used to render a series of images (of the hand) like this:
for i in range(last_frame):
bpy.ops.anim.change_frame(frame = i)
bpy.data.scenes['Scene'].render.filepath = '/home/user/Pictures/frame%d.jpg'%i
bpy.ops.render.render()
do you know of any Open Source software that could help me perform such a thing: converting a gray-scale image to an eye-catching colorful rendering. I was thinking about ImageMagick (along with EBImage package) or Gimp while resorting to a Script-Fu. Also, being able to automate the process would be great.
I thank you for sharing a fraction of your valuable time in answering my question.
Good day,

You looking for LookUp Tables (LUT). See ImageJ wiki.
Just install ImageJ or it's Fiji distribution, open your image and select Image > Lookup Tables > Choose one nice. If your image is not really grayscale (not one-channel), program raises an exception like LUTs cannot be assigned to RGB images. If so, select Image > Type > 8-bit and apply LUT again.
Use macros or language bindings (I use Jython) for automation.
I want to have a subscript and superscript in my GUI in Matlab. So far I have tried to use x_2 and x^2 and neither of them work. Is there anyone who knows how to do this?
Thanks in advance!

You can use an undocumented feature of all Matlab uicontrols, which is
the fact that they use underlying Java Swing controls, and these in
turn accept any valid HTML strings. So you can do the following for
example:
uicontrol('string','<html><b>1<sub>2</sub>3<sup>4</sup>5</b></html>')
This is equivalent to the tex string '\bf1_23^45\rm'. You can set font
faces, colors, sizes, bold/italic and any other valid HTML 3.0
property. It's limited, but should do the trick in most conceivable
cases.
The same is true for tooltips, by the way: try setting multi-line
(<br>) multi-colored (<font color="red"> ... </font>) tooltip once and
you'll never use the standard boring single-line black tooltip
again...
And just in case you were wondering - yes, it also works for menus,
listboxes etc.
This open source fractal program Fraqtive, which uses Qt, has a really cool little gradient editor for coloring your fractals:
http://fraqtive.mimec.org/node/34
Does anyone know of any nice gradient editing interfaces that use wxWidget/wxPython?
I wrote one for a fractal program I wrote in wxWidgets; I've been meaning to wrap it up nice and release on wxCode when I had time.
This is inspired by photoshop's editor, so it may not be exactly what you're looking for.
The code for it is hosted here:
http://github.com/ecordell/chaostools/tree/master/src/
And the relevant files are: gradient.h, gradient.cpp, gradientdlg.h, gradientdlg.cpp
The wxGradientDialog object works just like any other dialog, and returns a wxGradient object, which uses a lerp to create the gradients from the color stops.
Try the PyColourChooser or the CubeColourDialog
