We had a little bit of fun in the 2nd Monitor this morning, one user greeted another with a hex string. It turned out that the user being greeted deals with Hex Dumps enough that they were able to read the string, but I wasn't so I created this converter. What could I have done to reduce the dep...

In the past three days, I've been developing a simple raycasting algorithm. I've made the renderer work as I'd like to. However, it is extremely slow (5 frames per second) because of two things (as far as I know). Finding the values of a pixel independently many times, and often it lands on the...

I want to compare user input values with what I defined (compare with data in the database if possible?) and if it is ture (here is if key_in == 'a') then head to another PHP called downloads.php. Hope anyone can help me :) // Define variables and initialize with empty values $key_in = ""; ...

The two method get the same sequence, if the algorithm not same, how to seep up the second method, and is there third method get the same sequence? method 1: # http://oeis.org/A179382 # largest odd divisor of n; or odd part of n. http://oeis.org/A000265 def A000265(n): while not n % 2: ...

Given a string, return the sum of all the numbers in the string, 0 if none are present. Below is my solution for the problem above. I feel like this can be turned into one line. I would really only like suggestions on the actual algorithm, but anything else is appreciated. def sum_numbers(s...

Given a string, assuming the string is numbers only, rearrange the string to that it is the greatest possible number. Below is my solution to the problem above. I'd like feedback mainly on the algorithm, as I wrote this up very quickly. I used comprehension syntax to find the largest num, wh...

I am running an event loop which has the option to stop a double loop at any time. To break the double loop I have come to a solution where I create the indices in a generator and to flatten the double loop to a single loop where I simply can use break. Is this a best Pythonic solution? def indi...

I am building generic Graph where I will be improving. I want to know current design is fine? am I doing memory leaks ? Any suggestions are deeply appreciated Thannks GraphCode #include <iostream> #include <memory> #include <vector> #include <atomic> #include <map> namespace AtomicOps { int...

When I key in a value that exists in the database (the column name is "job_no"), nothing happens i.e. neither show errors nor redirect to another page. Please help me have a look at codes. What am I doing wrong?? <?php // Initialize the session session_start(); // Check if the user is logg...

I have implemented a Ternary search tree. It works well. But if you think something needs to be improved, say it. This code was tested in Python 3.7.4. class Node(object): def __init__(self, character): self.character = character self.leftNode = None self.middleNode ...

So I'm writting some code which works perfectly but bothers me a lot: For i = 3 To UBound(arr) If arr(i, 4) = 0 Then Exit For Login = arr(i, 4) Agentes.Logins(Login).Negocio = DatosAgente("NEGOCIO") Agentes.Logins(Login).Mes = DatosAgente("MES") Agentes.Logins(Login).Año = Da...

I've written a module for repeating blocks of code, generally to cover issues related to eventual consistency and testing screen elements which may take some time to fully load. It looks like this: class Repeater def initialize(&block) @repeat_block = block end def repeat(times: 25, d...

Hi fellow Developers/Programmers! I just started Developing Web App (Vue.js) for my company for around 1-2 months. Therefore, my knowledge and experience in HTML, CSS and Javascript is kinda shallow. I've created a custom resizable split DIVs and it working just fine as what I wanted. However, ...

I need to grab specific fields from several csv data log streams using a PCRE RegEx. All the fields in the log files are on a single line. ^(A|B|C)[0-9]{5}.*| ^(QWE|ASD|ZXC)(\\|\/)(A|B|C)[0-9]{5}.*| (?![\s\S]) Some example are fields that start with A12345, A123456_R, B12345T, QWE\C123456, ASD...

I work with electronics test equipment. I like to be able to automate tests using their remote control interfaces. I have built a pattern, a few base classes, that I can apply to all devices that follow the SCPI protocol. I would like to avoid half-assing the implementation like every time before...

I designed a (q)spi controller which can be configured over generics in QSYS(Quartus) and acts as an avalon slave. The documentation started in german, so please bear with the partial translation. I want to know if I can improve my signal handling or naming of my variables (or lets just say: wh...

When I put down my mug 18 months ago, I promised I'd stick around, and I did. I've been keeping a distant eye on CR and meta, while remaining in our Rubberducking dev chat, and monitoring vba posts on both Code Review and Stack Overflow. Seeing rolfl's resignation and the bleeding of several SE ...

I'm writing a program to calculate the longest collatz sequence for positive integers below some N. I have optimized it as far as I can - is there anything more I could do to optimize it? Any constructive criticism is welcome :) A few interesting notes: It is easy to prove (by contradiction or ...

I need help with bubble sort. Is there any possibility to optimize the following code? How do you put it in one on the 'if' to make it work? I tried it myself but I can't do it void sort(person tab[] , int n) { person tmp; for (int i = n-1; i >0; i--) { for (int j = 0; j < i;...

The code i did for a simple app that gives us random images, the code works but i feel like im doing somenthing wrong.
