It’s like as soon as we have the good jobs and good pay, that’s when they’re like, “Alright everyone, we’re changing the system!”
I’ve seen this traffic sign in Switzerland. What does the second panel from the top mean? The panel is a rectangle, maybe 1½ times wider than high, depicting on the left a symbol that looks like a darts missile drawn within a rhombus, and on the right the text ►1,8m◄. The latter may indicate a maximum width but there is a different panel for that, so I expect the meaning to be a bit different.
I could not find this sign on this list of traffic signs in Switzerland and Liechtenstein.
Something is only permitted with AWD when having permission from the municipality of Ennenda, but what?
A few km away I saw the panel again, with the same symbol on the left, but on the right a maximum mass (12 t) rather than a maximum width:
I have this image:
I want to whiten the black contours (borders) around it without affecting the image content. Here is the code I used:
import cv2 import numpy as np import shapely.geometry as shageo img = cv2.imread('filename.jpg') # get the gray image and do binaryzation gray = cv2.cvtColor(img, cv2.COLOR_RGB2GRAY) gray[gray < 20] = 0 gray[gray > 0] = 255 # get the largest boundry of the binary image to locate the target contours, _ = cv2.findContours(gray, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE) rect = cv2.minAreaRect(contours) box = cv2.boxPoints(rect) box = np.int0(box) poly = shageo.Polygon(box) h, w = img.shape[:2] ind = np.zeros((h, w), np.bool) # check if the point is inside the target or not for i in range(h): for j in range(w): p = shageo.Point(j, i) if not p.within(poly): ind[i, j] = True # whiten the outside points img[ind] = (255, 255, 255) cv2.imwrite('result.jpg', img)
Here is the result:
As you see, the code works fine, but it’s very slow because of the
Any suggestion how to avoid the for loops or to make them faster?
I have a ryzen 1600, MSI B450 Tomahawk motherboard, RX 580 4GB and am using Kubuntu 19.04. My only power setting is the default that the screen will turn off after 10 minutes but never suspend. If I leave it for a couple hours I will come back and just not be able to turn the screen back on even though the power light is still on and the fans are still on normally. It’s kind of frustrating if I leave something I’m working on to go do something else and come back and have to hard reset the PC.
When I select which boot I want in the new grub of Ubuntu 19.04, a large solid black appears that mostly (but not completely) covers the grub menu while it is booting up. It causes no discernible problem but is cosmetically ugly. Any way to get rid of it?
I have a plot where I stack the color white and black as values by month. I would use white as background color but the data is black and white as the color is. I’m using blue which I don’t like. Any suggestions what I can use for my background? Or highlight them from the background?
Often, when I try make a call or use the phone app on my phone, the screen goes black. I have a Pixel 1 with Android version 9. This is a problem because I can’t see or use the numbers or buttons on the screen! What is the fix?
I was wondering whether I can write a program and compile it and give the exec file to my friend. But this exec file must work as a black box. He should be only be able to interact with it without knowing what is the code I have written. Is this possible with Java or C++??
Downloaded and installed the latest update. The problem, I have a blank black screen now and it does not boot through. Do I reinstall or is there an easier fix? I have Ubuntu 18.04/10(?).
I have problem with booting my ubuntu on laptop.
After boot I have only black screen. I can hear sounds by pressing volume buttons, I can enable cli mode, but Im not able to do anything else. Only solution for that is closing my laptop and opening it again. It acts exactly like on this video: https://www.youtube.com/watch?v=cLzAR2ed4EY
I already tried to use quiet splash, nomodeset, grub_gfxmode=… etc.
What can I do to fix that?
Im using Lenovo Yoga 11e 3rd gen with Intel Celeron N3150 and integrated graphic card. I have same problem on ubuntu 19.04, 18.04.2. Also tried Kali and Mint but with same result.
