I have a Model called UserAccount, I have tried several ways to update the data for an existing user, it responds that changes are successful without any error but still nothing is reflecting in Database Here is the Model class UserAccount(AbstractBaseUser,PermissionsMixin): first_name = models.CharField( max_length=100) last_name = models.CharField(max_length=100) email = models.EmailField(_("email"),validators=[EmailValidator()],unique=True) date_added = models.DateTimeField(auto_now_add=True) phone = models.CharField(max_length=20, validators=[RegexValidator(r'^\d{12}$', 'Enter a valid phone number.')]) profile_picture = models.ImageField(upload_to='media/users_photos/%Y/%m',null=True,blank=True) employee_id = models.IntegerField(validators=[MinValueValidator(1), MaxValueValidator(999)], null=True,blank=True) is_staff = models.BooleanField(default=False) is_active = models.BooleanField(default=True) last_l

I have the following problem, for which the solution I use at the moment is too slow. Instance: a numpy array b of shape (B,2) , a sorted numpy array x of shape (X) , and a sorted numpy array y of shape (Y) . Note that x = np.unique(b[:,0]) and y = np.unique(b[:,1]) , if that makes a difference for the problem. Task: Build the (X,Y) -array H such that H[i,j] is the number of rows in b whose first entry is less than x[i] and whose second entry is less than y[j] . The following example code solves this: import numpy as np b = np.random.random((2000,2)) x = np.unique(b[:,0]) y = np.unique(b[:,1]) H = np.count_nonzero( np.logical_and( b[:,0,None,None] <= x[None,:,None], b[:,1,None,None] <= y[None,None,:] ), axis=0 ) but this gets quite slow if b and thus x and y have a few thousand entries. How can I do this more efficiently? source https://stackoverflow.com/questions/77044480/counting-the-points-below-a-coordinate

I am not able to find a best way to do it so i am asking here. I have an array of object let x = [{name: "Apple", message: {data: {}}, {name: "dell", message: {data: {}}, {name: "samsung", message: {data: {}} ]; now i have list of name that i need to check and if it is found in the array find the first one like let y = {laptop: ["Apple", "HP" ], phone: ["samsung", "Motorolla" ] What i need result = { laptop: { name: "Apple", message: { data: {} }, phone: { name: "samsung", message: { data: {} } } } this variable can be any data structure, right now best i can do is O(n ^2) and this check need to be done more than 40 times a second so i want to be done in efficient way. Is there any way i can do this in best possible way. Via Active questions tagged javascript - Stack Overflow https:

Longtime C# dev, just starting nextjs for a client. I'm using MUI, and basically have a day of work in, so my project is pretty small. I have a decent handle on how SSR works conceptually, but implementation is throwing me for a weird loop.

Graph-1 image of Graph-1 click to preview In the above graph there are 2 types of node , "Hidden Node" and "Non Hidden Node" which is connected to another node. The connection is call "edges" . "node" and "edges" data look likes : let nodes = [ { id: 1, node_name: "Node-1", is_hiddenable: false, hidden: false }, { id: 2, node_name: "Node-2", is_hiddenable: false, hidden: false }, { id: 3, node_name: "Node-3", is_hiddenable: true, hidden: false }, { id: 4, node_name: "Node-4", is_hiddenable: true, hidden: false }, { id: 5, node_name: "Node-5", is_hiddenable: true, hidden: false }, { id: 6, node_name: "Node-6", is_hiddenable: false, hidden: false }, { id: 7, node_name: "Node-7", is_hiddenable: false, hidden: false }, { id: 8, node_name: "Node-8", is_hiddenable: true, hidden: false }, { id: 9, node_name: "Node-9", is_hidden
