Wasted | Lock and wipe on emergency | iOS library

I was considering ways to reduce memory footprint, and it is constantly mentioned that a bool takes up more memory than it logically needs to, as a byproduct of processor design. it is also sometimes mentioned that one could store several bool within an int. I am wondering if this would actually be more memory efficient?

if we have a usecase where we can use a significant portion of 32 (or 64) bool. and we decide to store all of them in a single int. then on the surface we have saved

7 (bits) * 32 (size of int) = 224 (bits) or 28 (bytes)

but in order to get each of those bits from the int, we needed to use some method of masking such as:

• bit shifting the int both directions (int<>y here we need to load and store x,y which are probably an int, but you could get them smaller depending on the use case
• masking the int: int & int2 here we also store an additional int, which is stored and loaded

even if these aren't stored as variables, and they are defined statically within the code, it still ends up using additional memory, as it will increase the memory footprint of the instructions. as well as the instructions for the masking steps.

is there any way to do this that isn't actually worse for memory usage than just taking the hit on 7 wasted bits?

I need create an empty loop that runs for a given time, for example 2 hours. The loop just runs for nothing, no matter what it does, it is important that it loads R executions for exactly 2 hours.

for example, let's have some kind of script

In package.json file react-router-dom dependencies added. App component wrapped by BrowswerRouter , but when I wrap route by switch it says the following error Switch' is not exported from 'react-router-dom'. I deleted the package.json.lock ,node modules, installed npm again and npm install @babel/core --save. Still not working. I successfully wasted 6 hour for this. Can you please help me to fix this? why it's not importing?

I used a function in Python/Numpy to solve a problem in combinatorial game theory.

I am facing an issue with Docker for Windows application. This is happening after updating to newer version of 4.3.2. Previous version was running without any issues. After downloading and updating to new version, whenever I launch Docker Desktop I get error message " Docker failed to initialize. Docker Desktop is shutting down. ".

I have tried many solutions like:

1. Closed docker and restarted laptop after update.
2. Deleting log files in C:\Users\{...}\AppData\Local\Docker
3. Deleting files in C:\Users\{...}\AppData\Roaming\Docker
4. Tried to bump to previous release but unsuccessful with the message
   

Can anyone please help me resolve this issue as I have already wasted few hours to resolve this.

I am not sure if I should completely uninstall docker and install freshly. If doing so, may remove all existing volumes and containers. I don't want to lose existing containers and data. BTW, I didn't sign-in while working with containers.

Your help will be much appreciated.

Thanks in advance

P.S: I am working with Docker for Windows on Windows 10 machine with WSL2 enabled. I have also enabled Containers and Virtual Machine Platform in Windows Features.

I'd like to write an unsigned Big Int library in C++ as an exercise, however I would like to stay away from using the traditional vector of chars storing individual digits. Due to the amount of memory wasted by this approach.

Would using a vector of unsigned short ints (ie. 16 bit postive integers) work, or is there a better way of doing this?

To Clarify, I would store "12345678" as {1234, 5678}.

The terminal/console returns no error. I am confused as to where I am going wrong. The handleLeftClicks() is used to render the # of times the left button is clicked and respectively for right. The allClicks within History component is meant to render total # of clicks. I am unable to update both {left} and {right}. I tried console logging both the functions but couldn't get an output in the console.

I really apologise if this newbie question wasted your time.

I am creating a pixel art editor app and I already have one Room database which stores the users' creations and another Room database which I want to add which will store some custom color palettes the user wants to add to the app.

To do this I added the following database:

I'm using TypeScript and want to create a collection of objects. Each object has some properties. The combination of the properties must be unique inside the collection.

So these sample combinations would be valid
