CST205 Week 4

How Google sets goals: OKRs
Googles use of OKRs is interesting - by sharing it with the whole company it both motivates users to work harder and to be honest with their self-evaluations. It also allows employees to make sure their priorities are in line with management's goals and vice versa. Overall this was an interesting presentation.

Created a graphic portfolio that includes an fun new assignment (that will go well with my mid-term project ideas):
# CST205 Bonus - Programmer: John Lester pic = makePicture(pickAFile()) def betterBnW(pic = pic): pixels = getPixels(pic) for pix in pixels: r = getRed(pix) g = getGreen(pix) b = getBlue(pix) intensity = (r * 0.299 + g * 0.587 + b * 0.114) setRed(pix, intensity) setGreen(pix, intensity) setBlue(pix, intensity) repaint(pic) return pic def lineDrawing(pic = pic): pic = betterBnW(pic) threshold = 32 for x in range(0, getWidth(pic)): for y in range(0, getHeight(pic)): pix = getPixel(pic, x, y) lum = getColor(pix) if y < getHeight(pic)-1: bpix = getPixel(pic, x, y+1) blum = getColor(bpix) if x < getWidth(pic)-1: rpix = getPixel(pic, x+1, y) rlum = getColor(rpix) if distance(lum, blum) > threshold and distance(lum, rlum) > threshold: setColor(pix, black) else: setColor(pix, white) repaint(pic) return pic show(pic) pic = lineDrawing(pic)
which generated:

Fun with Green Screen

Code:
def chromakey(addition, targetFile, targetX, targetY, overRide = False): newPic = makePicture(addition) bckPic = makePicture(targetFile) for x in range(0, getWidth(newPic)): if x + targetX < getWidth(bckPic): for y in range(0, getHeight(newPic)): if y + targetY < getHeight(bckPic): pix = getPixel(newPic, x, y) bPix = getPixel(bckPic, x + targetX, y + targetY) color = getColor(pix) bColor = getColor(bPix) if (distance(color, Color(0, 215, 0)) > 50) and ((distance(bColor, Color(0, 215, 0)) < 60) or (distance(bColor, Color(0, 131, 0)) < 60) or (distance(bColor, Color(45, 221, 45)) < 60) or overRide): newPix = getPixel(bckPic, x + targetX, y + targetY) setColor(bPix, color) writePictureTo(bckPic, targetFile) return bckPic

Images (not to scale):

Commands:

pic = chromakey("C:\\Path\\to\\Images\\alien.jpg", "C:\\Path\\to\\Images\\newsBackground.jpg", 992, 170)

pic = chromakey("C:\\Path\\to\\Images\\apolloReal.jpg", "C:\\Path\\to\\Images\\newsBackground.jpg", 591, 107)

pic = chromakey("C:\\Path\\to\\Images\\johnl.png", "C:\\Path\\to\\Images\\newsBackground.jpg", 165, 175, True)

pic = chromakey("C:\\Path\\to\\Images\\ticker.jpg", "C:\\Path\\to\\Images\\newsBackground.jpg", 0, 0, True)

Result:

CST205 Week 2

I am already familiar with pair programming as this what we used for ACM-ICPC when I was at DVC.
