remnants | Find unused files . | REST library

I came across a weird behavior of file.readlines() and file.writelines() in python when I try to modify one of my text files. Could you please help me understand this unexpected behavior? It really confuses me a lot.

Here is a simplistic example, which can be used to reproduce the weird behavior: I know I can modify a text by reading its content, changing it, and writing to a text with 2 context managers like method 1 below, it works very well and is very robust (I always get what I expect):

method 1

Recently, I have had to reinstall the operating system on my machine. In the process I upgraded Dragon NaturallySpeaking (DNS) from v13 to v15 and in reconfiguring my voice recognition environment (DNS + Natlink + Dragonfly) the following Natlink message now appears on DNS start:

C# string's Splice method seems to copy remnants into an array of strings instead of just reading them. Is there a c++17 string_view equivalent to bypass copying?

For those not familiar with string_view, here is some background information.

From Microsoft's :

The string_view family of template specializations provides an efficient way to pass a read-only, exception-safe, non-owning handle to the character data of any string-like objects with the first element of the sequence at position zero. (...)

From Microsoft's C++ Team Blog std::string_view: The Duct Tape of String Types:

string_view solves the “every platform and library has its own string type” problem for parameters. It can bind to any sequence of characters, so you can just write your function as accepting a string view:

I am writing a simple calculator program such that the user is entered into the programs own console environment. Each new line starts with a $. User will enter commands such as '''sum(x,y)''' '''mul(x,y)''' etc. and the program will take x and y as doubles and execute a function i.e. '''double mul(x, y){return x*y)''' and display the returned value.

I have gotten it to correctly identify the command based on matching the first three characters in the string.

I cant seem to read the numerical values correctly no matter what I do. Any suggestions are greatly appreciated!

I'm trying to make a datepicker component from ngx-bootstrap a custom date-field, so that I can globalize some functionality and configs. But I can't seem to be able to catch the value of the Date object in the date input field.

My date-field.ts (I'm re-using some setup from a text-field. So bear with me if you see some remnants of the text field component. But I'm sure that my main problem is that my component doesn't know it's a date field)

I intended to clean up a chunk of memory then put a struct variable in it and assign new values in that newly cleaned memory, but I couldn't initiate the struct variable from the address which the pointer variable points to (ptr=00D51590). As indicated in the program output with red arrows, I cannot get rid of the remnants of old memory variables.

I am trying to remove horizontal and vertical lines from a image. This image is generated from a pdf using pdf2jpg library. Upon removal of the horizontal and vertical lines this image will be fed to pytesseract to extract words and their individual co-ordinates. Here I am just extracting the full text for testing purpose. I am new to OpenCV. I have written this code by accumulating code snippets from different websites including stack overflow. The code works almost perfectly other than there are some occasional remnants of vertical lines. This remnants are confusing the tesseract and sometimes is being treated as I, 1 or |. Also it seems like number of misreads(like s is read as 5, I is read as 1 or | and vice versa) by tesseract is higher for the processed image than the original image. I think the reason for that being the font sharpness is lower than the original image that we started with. What changes can be done to this code which will remove those remnants of vertical line without affecting the font sharpness. Any suggestions or guidance in right direction will be heavily appreciated. Thanks in advance

I'm building a gatsby site to show my photographs. I want a full-screen page for each photograph, and the photo should fill out the page, but respecting the aspect ratio.

The problem is that while photos shot in landscape orientation are limited correctly, photos shot in portrait orientation fill out all horizontal space but overflows the vertical space.

In the documentation there is the statement

As mentioned previously, images using the fluid type are stretched to match the container’s width and height

However, my observed behavior is that it only stretches to match the width, not height.

I simplified my problem into this small example, that tries to contain the images in a 400x400px container:
