Rust is one of my first forays on a strongly typed language, beginning to like it's strictness, and am looking to improve my comprehension. Questions Are there any mistakes that the compiler hasn't pestered my about? The iterator increments or decrements, any other directions it should go? It'...

I am working on struts 2 based web application, where an Action Class render 7000+ records in UI. The query which fetches the record is already been optimized by the DB developer, but instead it took around 7+ seconds to load UI it also freeze the UI for a moment,on deep inspection I have found t...

I am using the least_squares() function from the scipy.optimize module to calibrate a Canopy structural dynamic model (CSDM). The calibrated model is then used to predict leaf area index (lai) based on thermal time (tt) data. I tried two variants, the first did not use the "loss" parameter of the...

I have figured out two ways to return a pdf from a pyodbc row with flask. ( the row data must be gunziped too in this case ) With a simple timing decorator I can find no obvious difference in speed. I was hoping the later version would avoid loading the whole pdf into memory, but I now realize I ...

I have a system of 49 equations and 49 unknowns. All equations have the following form. where s = 1,...,S with S = R = 50 and T = 30. The a's, the b's and x_{50} are known parameters. Since all equations have the same form, I believe that vectorizing the problem is possible. I appreciate any ...

I do genetic programming. I have 5 parcours, the first on the left is the easiest parcour. The first parcour can be solved by place one belt in the middle pointing downwards to solve the problem. If placed in the middle downwards, the puzzle is solved because the iron-ore flows downwards to th...

Currently my solution for calculating wages based on average weekly hours and any other wages field is very long and elaborate. I think it can be concised and make more readable but when I try to do it it creates some nasty bugs as it is based on field changed. Any elegant refactoring suggestion ...

Challenge taken from Hackerrank. Available at: https://www.hackerrank.com/challenges/30-dictionaries-and-maps/problem?isFullScreen=true The challenge was to add a number of entries to a dictionary and then return the keys and values as queried in the format of "Key=Value". I solved the problem ...

Is this the best way to prefix all lines written by a Bash script to standard error? #! /bin/bash exec 3>&2 exec 2> >(sed 's/^/ERROR: /' >&3) echo stdout echo stderr >&2 I am wondering, if I have to close file descriptor 3.

I've created a tiny (723 bytes compressed + gzip) animation library. Is this a good way of animating arbitrary numbers? const map = (value, x1, x2, y1, y2) => (value - x1) * (y2 - y1) / (x2 - x1) + y1; const clamp = (value, min, max) => Math.min(Math.max(value, min), max); // Courtesy of @gre f...

I've got such an input object, which I should modify in order to use it with some charts library. const input = { foo: { bar: 'biz', }, statistic: { "2019-11": { A: 11, B: 11, C: 11, D: 11, E: 11, }, "2019-12": { A: 12, B: 12, ...

How can I avoid use cursor to implement the following? I read that it can be done with CTE but I didn't get it working with the same result. In the example I am using two tables, the first one is the holders table containing a list of people and the transfers table where each transfer indicates ...

I have pieced together the below. However it will only run in Powershell ISE and I cannot work out where I am going wrong.

I have an "update" form for users. - I have a drop-down field with the list of countries: countries = [{code: "BE", name: "Belgium"}, {....} ...] The user ( from a Observable with name "user"): user = [name = "Arthur", country = "BE", ...] In the observable from user, I don't have the country n...

I just got done coding this C program: Read the description of a deterministic finite automaton from standard input. The first line of input is the number of states in the automaton, n n lines follow, each one describing a state. Each line is composed of the name of the state, follo...

I have been following along with a Udemy OOP basic course in Python, and one of the sections says to attempt a banking system before watching the videos. I have done what is required, however it is very basic and I know there are tweaks to be made. However I am more concerned that I did not use a...

I'm implementing the Kruskal algorithm using a Graph class defined by me in java. My main aim is to obtain a fast execution(less than 5 seconds). This is how i've defined my graph class : Here i've implemented all my util functions to make my algorithm work properly package graph; import java.u...

I was thinking of adding a very high-level implementation of the event/observer pattern to my project. The implementation would manage adding and removing observers as "needed". You can use an almost DLS-like API to define when an observer should be added or removed. Here is an example of the AP...

I have a form for the user's address. In this form, I use "matGoogleMapsAutocomplete" to automatically complete the fields "street, number, postal code, city". Until then, everything works, but I'm limited to only one country, I have a drop-down list "input select->option" with the countries in m...

Based on my answer to another code review question I wrote my own python script for DLA (Diffusion Limited Aggregation). The DLA algorithm task: Place seed at the center of the canvas. Release a random walker from the edge. Random walker sticks to the neighboring sites of the seed/previous poi...

I was hoping somebody would be able to give me feedback on my program. For example, have I made good use of structs, vectors, and could I improve on any code-structure, perhaps a better way of doing something? I'm obviously not expecting someone to go through each part but just perhaps anything t...
