QUESTION
I am trying to learn how pointers work on go. Why is the following example not working?
...ANSWER
Answered 2022-Apr-15 at 09:04Create() returns a value of type interface{}, so type of x is interface{}, so type of &x is *interface{}, and not *SliceOfStrings. So x points to an interface{} value and not to a SliceOfStrings value!
If you type assert SliceOfStrings from the return value of Create(), it works:
QUESTION
It looks like the typeof operator is likely to be accepted into the next C standard, and I was looking to see if there was a way to leverage this to create a macro using portable ISO-C that can get the length of an array passed into it or fail to compile if a pointer is passed into it. Normally generic selection can be used to force a compiler error when using an unwanted type by leaving it out of the generic association list, but in this case, we need a default association to deal with arrays of any length, so instead I am trying to force a compiler error for the generic association for the type we don't want. Here's an example of what the macro could look like:
ANSWER
Answered 2022-Mar-18 at 02:34It doesn't matter which generic selection is evaluated.
When the expression that is part of a _Status_assert has the value 0, this is considered a constraint violation and the compiler is required to generate a diagnostic.
QUESTION
I am training a Unet segmentation model for binary class. The dataset is loaded in tensorflow data pipeline. The images are in (512, 512, 3) shape, masks are in (512, 512, 1) shape. The model expects the input in (512, 512, 3) shape. But I am getting the following error. Input 0 of layer "model" is incompatible with the layer: expected shape=(None, 512, 512, 3), found shape=(512, 512, 3)
Here are the images in metadata dataframe.

Answered 2022-Mar-08 at 13:38Use train_batches in model.fit and not train_images. Also, you do not need to use repeat(), which causes an infinite dataset if you do not specify how many times you want to repeat your dataset. Regarding your labels error, try rewriting your model like this:
QUESTION
I want to position a legend (common to all plots) in a blank space in a patchwork layout. From what I can find online I cannot manually position a legend using legend.position if I also use guides="collect" (but can use left, right etc.).
I have tried to use l <- get.legend and then + inset_element(l, 0.6, 0.6, 1, 1) however it doesn't understand l. I also tried mixing in + inset_element(gridExtra::tableGrob(l)) without luck.
My goal is to place the legend in the blank space. My actual patchwork plot is more complicated but has two blank spaces I want the legend to sit in.

QUESTION
Question: How do I get the location of a point after rotation?
Goal: I want to create a triangle given two angles. The user can manipulate two angles (a0,b0) and the program will determine the third vertex based on the intersection of the two sides.
Explanation: To find the point of intersection of the two sides, I need four points: the endpoints for l1 and l2. To keep track of the points, I created vertices=[]. But the array doesn't update the location of the points after the user rotates the sides and changes (a0,b0).
Thus, when I retrieve my points, two of them are in their initialized position, and have not been updated after the user rotates the sides. I've searched for this problem online, but to no avail. Any help is appreciated.
MWE:
...ANSWER
Answered 2022-Feb-14 at 06:14In a word: trigonometry. Instead of using the rotate() function to rotate the drawing frame of reference, use trig to calculate the various vertex positions. Here's code with comments which hopefully explain how this is done:

I have checked an old dotnet program which my dockerfile was working perfectly. I got the same error. Then, I jumped to Docker Hub and checked the MS Images to see that all MS images have been updated for an hour. And then they have been updated once again, 10 Minutes ago xD. However, I still cannot pull the base images of mcr.microsoft.com/dotnet/runtime:3.1 and mcr.microsoft.com/dotnet/sdk:3.1. My whole Dockerfile is:

It is kind of strange because I already updated my Docker Desktop, restarted, and cleaned/ purged the docker data. None of those helped, just after restarting my windows it works again!
QUESTION
struct X { int n; };
const X *p = new const X{3}; // #1
new (const_cast(p)) const X{5}; // #2
const int c = std::launder(p)->n;
ANSWER
Answered 2022-Jan-17 at 18:46[basic.compound]/3 is not relevant. It specifically says that it applies only for the purpose of pointer arithmetic and comparison. There doesn't actually exist an array for the object.
I think when you call std::launder, there are four objects at the relevant address: obj1, obj1.n, obj2 and obj2.n.
obj1 and obj1.n are pointer-interconvertible, as are obj2 and obj2.n. Other combinations aside from identical pairs, are not pointer-interconvertible. There are no array objects and therefore "or the immediately-enclosing array object if Z is an array element." isn't relevant.
When considering reachability from std::launder(p), which points to obj2 thus only obj2 and obj2.n need to be considered as Z in the quote. obj2.n occupies an (improper) subset of bytes of obj2, so it is not relevant. The bytes reachable are those in obj2. Except that I considered obj2.n specifically, this is a rephrasing of your considerations.
By exactly the same reasoning, the bytes reachable from p (pointing to obj1) are all those in obj1.
obj1 and obj2 have the same size and therefore occupy exactly the same bytes. Therefore std::launder(p) would not make any bytes reachable that aren't reachable from p.
QUESTION
In my pygame-code, I have a drone that is supposed to follow a flight path.
I used pygame.draw.lines to draw lines between specified points. Now, I have a flight path with 10 points where after each point the path angle changes (a bit like a zigzag). The player can move the drone by pressing the keys.
My goal is to print a warning once the drone deviates from the path, e.g. by +/-30. I have been racking my brain for two days but can't come up with a condition to detect a deviation. I just can't figure out how to approach this.
I can determine the drone's x-coordinate at any time but how do I determine the offset from the path? I have attached an image to visualize my problem.
Edit: As I am a beginner my code is a mess but when copy-pasting it, I guess only the lines 35-91 are interesting. Thank you for any kind of advice in advance!!
...ANSWER
Answered 2021-Dec-27 at 01:52The interesting part of the question is of course finding the nearest point on the desired path to the actual position; distance is easy. The hard part of that is in turn identifying the nearest element (line segment) of the path; projecting onto it is also straightforward.
If the path is simple enough (in particular, if it doesn’t branch and it’s impossible/disallowed to skip sections at a self-intersection), you can finesse that part by just maintaining that current element in a variable and updating it to the previous or next element when the projection onto one of them is closer than the projection onto the current one. This is a typical algorithm used by racing games to determine the instantaneous order of racers.
