kandi X-RAY | Cereal Summary
Cereal is a serialization framework built for Swift. Its intended as a substitution for NSCoding to allow advanced Swift features. With NSCoding, you cannot encode or decode a Swift struct, enum, or generic class. Cereal solves this issue through deferred decoding with generics, and a protocol that doesn't depend on NSObjectProtocol. Please note that the data stored in Cereal 2.0 is different from Cereal 1.3, and while the API is the same they are not compatible. Do not expect data written by 1.3 to be readable by 2.0.

QUESTION
I have been trying to replace part of the texts in a Pandas dataframe column with keys from a dictionary based on multiple values; though I have achieved the desired result, the process or loop is very very slow in large dataset. I would appreciate it if someone could advise me of a more 'Pythonic' way or more efficient way of achieving the result. Pls see below example:

QUESTION
I'm trying to link OpenGL to an application for Windows (building on Windows).
I'm using Conan as package manager, CMake for building and MSVC as compiler (and CLion as IDE).
The program compiles, but I have linker errors, for what I believe to be extension functions in OpenGL:
...ANSWER
Answered 2021-Jun-10 at 14:30I'm compiling with
GL_GLEXT_PROTOTYPES=1
.
Well, don't do that. That is never going to work in a portable way. On windows, the opengl32.dll
always exports only the functions which are in OpenGL 1.1, and for everything beyond that, you have to rely to the OpenGL extension loading mechanism at runtime.
I have tried:
- [...]
- Adding GLEW
That's a step in the right direction. But this does not make things to magically work. A GL loader like GLEW typically brings its own header as a replacement for GL.h
and glext.h
etc., and the typical GL loader (like GLEW) simply re-define every GL functions as a macro, like this:

See code below and log. I am working on a google sheets script that updates a google sheet when a linked google form is submitted. To do this I am using the array "event.namedValues", which is generated automatically when a form is submitted. However while debugging some issues (and learning how to do this), I wanted to check the length of the array I was working with and it would return "null". When I tried adding the .length property of the array to 0, the logger logged "NAN" (See log below). What am I doing wrong?
Code Sample:
...ANSWER
Answered 2021-Jun-03 at 22:59Since e.namedValues is an object, it does not have a length property.

I have the following query and I'm facing some performance issues when the offset is getting higher and higher.

try and let me know if moving subquery to the join section helps at all , also I removed an extra join with person table:

I am trying to loop the object output with event, but for some reason I am missing something. codepen
...ANSWER
Answered 2021-May-20 at 18:16In your loop, I believe that you want to create a new child and add it to the display div.
When you click on one of the children, you need to access it via event.target

QUESTION
I am building a chrome extension and hoping to customize it by adding icons.
The extension is using vanilla JS, so we create our HTML elements using js. I have been able to use imported .png icons in the HTML popup, but when I am in my js file and try to set the img src to the correct path of the .png I get an error that looks like chrome is adding my path to the end of the current URL. Obviously that URL doesn't exist, so I error out and never see the icon.
Why can't I do ?
sounds similar to what I am trying to do, but I don't want the image saved on my drive anywhere, I want it from within the project. Adding file://
or e://
before the path didn't work anyway.
I do see a Not allowed to load local resource:
error when I prepend with file://
so maybe it really is a security issue?
Is it simply going to be a security concern to add an icon to my buttons? anyone know of a work around? Maybe someone knows of an online library where I could grab a url of an icon similar to https://fontawesome.com/icons/exclamation-circle?style=solid (I haven't been able to create an element from that html button either)
Ideally, I would be able to use the icon png my product team provided. I am starting general just trying to get the icon to show up on the page where I have other elements appended. Here is what I have done to add the icon so far:

I have an image that has cereal items below:
The image has:
- 3 walnuts
- 3 raisins
- 3 pumpkin seeds
- 27 similar looking cereal
I wish to count them separately using opencv, I do not want to recognize them. So far, I have tailored the AdaptiveThreshold method to count all the seeds, but not sure how to do it separately. This is my scripts:
...ANSWER
Answered 2021-Apr-27 at 06:50Your lighting is not good, as HansHirse suggested, try normalizing the conditions in which you take your photos. There's, however, a method that can somewhat normalize the lighting and get it as uniform as possible. The method is called gain division. The idea is that you try to build a model of the background and then weight each input pixel by that model. The output gain should be relatively constant during most of the image. Let's give it a try:
