Per the description of Recursive Types, variadic tuples aren't supported, one the three types listed below:
The specific change made by this PR is that type arguments are permitted to make circular references in aliased types of the following kinds:
Instantiations of generic class and interface...
I was trying to get cast reflection field to Map, but it gives me this error:
java.lang.ClassCastException: java.lang.reflect.Field cannot be cast to java.util.Map
How do I fix this?
Code:

I was reading about the cmake keywords PUBLIC, PRIVATE, INTERFACE and came across this paragraph here in the cmake docs.
Generally, a dependency should be specified in a use of target_link_libraries() with the PRIVATE keyword if it is used by only the implementation of a library, and not in the ...
I have a dataset with mesh opening measurements and the tools used to get those measurements. I want to complete a one-way anova on the data. Here's my code:

You could flip the camera (and apply other interesting effects) with shaders!
FlxCamera has a function called setFilters() that allows you to add a list of bitmap filters to an active camera.
Here's a simple filter I wrote that flips all textures horizontally:
import openfl.filters.ShaderFilter;

You miss nothing. Unless some other code path an lock guard_mtx_2 before locking guard_mtx_1 there is no deadlock. The out-of-natural-order unlock is harmless (and occasionally we must do this).
Deadlocks occur when two code paths can lock the mutexes (sp? should it be mutices? my spellchecker do...
I want that my array num cosist of each char from my string b
like this:
num[0] = 9;
num[1] = 1;
num[2] = 1;
num[3] = 9;
but somehow the 9 turns into a 57 and the 1 turns into 1. I dont get why. When i print out b.charAt(i) the numbers are correct but as soon as i try to initialze the array the ...
The remove() function removes the object from the state, which is causing the odd behavior. You only want to disable the object.
Try changing the line remove(brick) to instead brick.kill() and see if that resolves your collision problem.
I'm reading the code at https://doc.rust-lang.org/1.56.0/src/core/str/mod.rs.html#120-122:

impl str {

and I can't find a reference to this attribute lang. Does it have something to do with declaring the structure of the primitive type str? And if so, where i...
I'm making an "ascending number" effect with currency. The page loads and then a extremely fast count start from 0.00 to a decimal number given by an API. I'm using a setTimeout inside a for loop. Everything until here works fine but when the for loops ends, the number after the decimal point is ...

Using virtualenv, I'm developing a Dash/Python app. After adding a new package, I ran
pip freeze > requirements.txt
and then tried to push the new changes to the linked Heroku server using git. Before this comment, the previous version on the server was running without an error.

This is a known issue and seems to be related to VirtualBox.
There is a healthy and detailed thread in the official HashiCorp repo for Vagrant about this: “Vagrant up issues in Mac OS Monterey #12557”
The issue seems 100% unrelated to VirtualBox 6.1.28 or even the earlier 6.1.26 since people repo...
I am doing a vulnhub CTF walkthrough (Lampiao). I have my main VM set up using Kali Linux in VirtualBox. The victim VM is the Lampiao machine. I am supposed to run Netdiscover on Kali to search for the IP's of all machines on my network. I have both machines set to NAT.
When I run Netdiscover f...
I got the same 0x112f issue when using mstsc client today. The issue is gone after I changed the color depth from 32bit to 16bit in mstsc. I don't know why but it works. My remote desktop OS is Win10 and local OS is also Win10.

I have the problem that a child component is not re-rendered when I change a prop value via the parent component.
Parent component:

The issue is that you're mutating the current state object rather than setting a new state object. React relies on checking referential equality when determining if state changes; mutating the object will not be seen as a new object in memory, and therefore will not prompt a rerender.
One quick w...

The expression string(bytevalue) is a conversion, not a typecast.
The specification says this about conversions from numeric types to a string:
Converting a signed or unsigned integer value to a string type yields a string containing the UTF-8 representation of the integer.

I usually use a function and then call it to generate that column. Another nice thing about this is you can add args to customize the column config.

I guess Scipy and Numpy is not directly supported on arm64 processor (MAC M1 OS BigSur and higher versions) which requires the users to manually install and build the dependencies. I figured a work around by creating a virtual environment with Python version 3.8. Once the final releases are rolle...
