Answer : Solution 1: No, There is no method to specify or provide on the command line the password in a non-interactive manner for ssh authentication using a openssh built-in mechanism. At least not one what I know of. You could hardcode your password into expect script but it is not a good solution either. You definitely would want to use keypairs for passwordless authentication as Michael stated, in the end private key is pretty much a big password in the file. Solution 2: To avoid the string of comments: Yes, this is insecure (not even arguably insecure). I would strongly recommend you only do it in a lab situation on an isolated network or a similiar situation that does not involve production servers or potentientially production server without a full reset/format. I wanted to set this up as I don't think my 2950 switch supports private/public keys and I hope at some point to get that knowledge, but I am not there yet. Using an alias and sshpass this can be acc

Example 1: php sprintf There are already some comments on using sprintf to force leading leading zeros but the examples only include integers . I needed leading zeros on floating point numbers and was surprised that it didn't work as expected . Example : < ? php sprintf ( '%02d' , 1 ) ; ? > This will result in 01. However , trying the same for a float with precision doesn't work : < ? php sprintf ( '%02.2f' , 1 ) ; ? > Yields 1.00 . This threw me a little off . To get the desired result , one needs to add the precision ( 2 ) and the length of the decimal seperator "." ( 1 ) . So the correct pattern would be < ? php sprintf ( '%05.2f' , 1 ) ; ? > Output : 01.00 Please see http : //stackoverflow.com/a/28739819/413531 for a more detailed explanation. Example 2: php sprintf < ? php $num = 5 ; $location = 'tree' ; $format = 'There are %d monkeys in the %s' ; echo sp

Answer : Both are correct, but none of them are "best" per se, and there may be a reason the developer chose to use both approaches. Event Listeners (addEventListener and IE's attachEvent) Earlier versions of Internet Explorer implement javascript differently from pretty much every other browser. With versions less than 9, you use the attachEvent [doc] method, like this: element.attachEvent('onclick', function() { /* do stuff here*/ }); In most other browsers (including IE 9 and above), you use addEventListener [doc], like this: element.addEventListener('click', function() { /* do stuff here*/ }, false); Using this approach (DOM Level 2 events), you can attach a theoretically unlimited number of events to any single element. The only practical limitation is client-side memory and other performance concerns, which are different for each browser. The examples above represent using an anonymous function[doc]. You can also add an event liste

Answer : Problem 1 : Different applications use different scales for HSV. For example gimp uses H = 0-360, S = 0-100 and V = 0-100 . But OpenCV uses H: 0-179, S: 0-255, V: 0-255 . Here i got a hue value of 22 in gimp. So I took half of it, 11, and defined range for that. ie (5,50,50) - (15,255,255) . Problem 2: And also, OpenCV uses BGR format, not RGB. So change your code which converts RGB to HSV as follows: cv.CvtColor(frame, frameHSV, cv.CV_BGR2HSV) Now run it. I got an output as follows: Hope that is what you wanted. There are some false detections, but they are small, so you can choose biggest contour which is your lid. EDIT: As Karl Philip told in his comment, it would be good to add new code. But there is change of only a single line. So, I would like to add the same code implemented in new cv2 module, so users can compare the easiness and flexibility of new cv2 module. import cv2 import numpy as np img = cv2.imread('sof.jpg') ORANGE_MIN = np.

Answer : You can too override default datepicker classes like the following: the default bootstrap font size is 1rem or 16px so update .datepicker class font-size: 0.875em; or/and update the cell width and height: .datepicker td, .datepicker th { width: 1.5em; height: 1.5em; } <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.7.1/css/bootstrap-datepicker.min.css" rel="stylesheet"/> <link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous"></head> <body> <main class="cont
