How can i find the offset rotation and position between two objects in 3D

I have two objects in 3 dimensions, one of them (Child) is attached to the other one (Parent) using the offset between them (XYZ – position and rotation). Using the Vector3 library, how can I find that Child offsets from the Parent?

further explination: let’s say we have the parent at position X:0 Y:0 Z:0 with rotations RX:0 RY:0 RZ:0, and there is an attached Child to it with the offset X:10 Y:10 Z:10, RX:90 RY:45 RZ:90 (which is what I want to know). Supposedly, I had the Parent with a different position and rotation, how can I get the offset between it and the Child (which in this case, it should be X:10 Y:10 Z:10, RX:90 RY:45 RZ:90) (in another word, I want the Child position and rotation as the Parent is the center of the map)

I’ve tried simple math and some other ways on the internet but with no success, since I’m pretty bad at calculating rotations (since vector3 libraries are pretty identical, so as Math libraries, any language should be fine).

Having trouble printing out an encoded message with an offset entered by the user

I am creating a program to take in a simple string from the user and encode then decode the string. I have that part completed, however it just came to my attention we need to get an offset from the user as well and offset the encoded string. I am having trouble setting the offset and then printing the encoded string. Feel as though I am overthinking it. Any guidance would be greatly appreciated.

The trouble I am having is figuring out how to take in the byte[] string and add the int offset to each item in the string then print it. Below is what I have. I only put the main class and the encoder class since this is the part I’m having trouble with.

public class EncodeDecodeTester {      public static void main(String[] args) {         Scanner input = new Scanner(;         System.out.println("Enter the message you want to encode: ");         String message = input.nextLine();         System.out.println("Enter the offset you would like: ");         int offset = input.nextInt();         Encoder encoder = new Encoder(message, offset);         System.out.println("Your encoded message is: " );         byte[] encoded = encoder.getEncodedMessage();          System.out.println(Arrays.toString(encoded));         System.out.println("Decoding your message. ");         Decoder decoder = new Decoder(encoded);         System.out.println("Your decoded message is: ");         String decoded = decoder.getDecodedMessage();         System.out.println(decoded);         }  }      public class Encoder {     public String message;     public int offset;     public Encoder() {         //this("Hello");     }     public Encoder(String message, int offset) {         this.message = message;         this.offset = offset;     }      public String getMessage() {         return message;     }     public void setMessage(String message) {         this.message = message;     }     public int getOffset() {         return offset;     }     public void setOffset(int offset) {         this.offset = offset;     }     public byte[] getEncodedMessage() {         String encodedMessage = message;         int offsetMessage = offset;         byte[] encoded = encodedMessage.getBytes();         for (byte i = 0; i < encoded.length; i++) {             encoded[i] = (int) offset + encoded;         }         return encoded;     }   } 

Warning: Illegal string offset ‘totalfuncionarios’

Criei uma view no banco de dados pra mostrar o total de linhas em uma tabela. Fica sempre retornando o mesmo erro, “Warning: Illegal string offset ‘totalfuncionarios’ “. Vou mostrar logo o código.


<?php      include("../acao/selecionar.php");     $  rowFuncionario = selectViewFuncionario();   ?> 

<?php foreach($  rowFuncionario AS $  viewFuncionario): ?>     <div class="alert alert-info" role="alert">       <?php print $  viewFuncionario["totalfuncionarios"];?> Funcionários — <a class="alert-info" href="funcionarios.php">Expandir</a>     </div> <?php endforeach; ?> 


function selectViewFuncionario(){     $  bd = conectaBanco();     $  sqlViewFuncionario = "SELECT * FROM totalfuncionarios";     $  resultado = $  bd->query($  sqlViewFuncionario);     $  row = mysqli_fetch_assoc($  resultado);     return $  row; } 

Best way to match timezone with time offset?

I have a c# solution which uses mssql database to store data.

In my database there is a big table of entities (e.g. accounts) for each of which the TimezoneId field is defined. This field is filled during the registration of a new account using the MaxMind GeoIP2 library.

+----+-------------+------------+ | Id | AccountName | TimeZoneId | +----+-------------+------------+ |  1 | account1    |          1 | |  2 | account2    |          1 | |  3 | account3    |          2 | |  4 | account4    |          3 | |  5 | account5    |          1 | +----+-------------+------------+ 

TimeZoneId as a foreign key for table TimeZones, which stores the names of time zones in the IANA time zone format (e.g., America/New_York).

+----+----------------------+ | Id |         Name         | +----+----------------------+ |  1 | Europe/Paris         | |  2 | Africa/Kampala       | |  3 | Africa/Dar_es_Salaam | |  4 | Asia/Karachi         | +----+----------------------+ 

Now I need to be able to select all the accounts from the database, the time zone for which match with utc offset specified by the user. For example, if the user specifies the offset “UTC+2” i want to select accounts with timezones “Europe/Oslo”, “Europe/Paris”, “Europe/Rome” and other that have this offset. Which solution in terms of performance is best suited for this task?

Expand the TimeZones table with utc-offset field, create a memory cache with data about time zones and offsets or something else? I would appreciate advice.

Is it possible to make game screen smaller or offset it?

When playing a game on the OnePlus 7 Pro, the game would take the whole screen. This mean that it will be displayed in the curved edge parts of the screen as well. This can make touching buttons near the edge awkward or ruin the art.

Is there a way to adjust the screen size when a game is launched so that the display doesn’t touch the curved edge?

Problem regarding caching. Block offset, Set index and Tag

I am currently reviewing for my exam in computer architecture. I’ve run into a question in the old exam sets that I can’t really figure out. The question is regarding caches, more specifically block offset, set index and tag. The question is as follows: enter image description here

The old sets come with solutions. The solution to the problem is as follows:

enter image description here

Unfortunately, it doesn’t state how to get there. I’m at a loss here and would really like to understand this. Any help would be appreciated 🙂
