| Rails 6 deployment to Heroku Posted: 12 Dec 2021 07:43 AM PST This is my first Rails Application.

| SvelteKit Navigation goto State Posted: 12 Dec 2021 07:43 AM PST In SvelteKit navigation goto allows to pass state in the second argument such as: import { goto } from '$app/navigation'; // ... goto('/login', { state: { foo: 'bar' } });
The documents do not make it clear how state can be consumed/retrieved after the resulting navigation has occurred. state does not seem to be present on $page nor seems to be available on $navigating. How do you consume state passed to second argument of goto()? Is it currently missing and you have to create your own writable store to manage this state? This is an adapter-static SvelteKit application. |

| Split date_start and date_end by hours on Metabase Posted: 12 Dec 2021 07:42 AM PST I have table with a column "Begin At" and another column "End At" that represent when a task begin and when a task end i would want to have a Bar display which display the cuantity of tasks that are being done in a specific hour along an interval of time. For example, from the following table 
I would want to be able to see that from 07/12/2021 21:00 to 07/12/2021 22:00 there were 3 tasks being done (row 1, row 2, row 3). And also as i will have several thousands of rows i would want to use the date widget from metabase in order to specify range of times. I have been struggling with this from the last week, i tried to create auxiliar questions where to query after but finally my only succeed was to hard code the 24 hours from a day but then i was not able to use the time widget and i needed to specify the dates myself on the sql each time i want to check a specific day and also i only was able to check from 24 to 24 hours, not from for example 02/12/2021 6:00 to 04/12/2021 18:00 My metabase is running on a PostgreSQL database. Is this even possible on Metabase? If not what are your advices to build this? Other plaforms? Pure SQL? Python? Thank you so much |

| Python closest subset function Posted: 12 Dec 2021 07:43 AM PST I'm writing a closestSubset(s,A) function that takes an integer s and an array of positive integers A and returns an array consisting of elements of A which add up to s. If there is no subset that adds up to s, I want the function to instead return the subset which adds up to the value closest to s. For example: if A is [12, 79, 99, 91, 81, 47] and s is 150, it will return [12, 91, 47] as 12+91+47 is 150 if A is [15, 79, 99, 6, 69, 82, 32] and s is 150 it will return [69, 82] as 69+82 is 151, and there is no subset of A whose sum is 150. # Driver code: subset = closestSubset(5000,A)
A typical recursive method might work here, but I would want to know a way of doing this iteratively if anyone knows. I understand how to produce this function if the correct numbers exist to form integer s but when there isn't, then how do I find the closest? Would I have to actually create a left and right range so that if for example the integer was 150, then any number closest to 150 by for e.g. 10 would be fine? |
| Scenario if in input numbers are repeat Posted: 12 Dec 2021 07:44 AM PST Code: n = int(input("Type n: ")) def some_function(n): numbers, numbers_sum = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0], 45 while True: digit = n % 10 n //= 10 if digit in numbers: numbers.remove(digit) numbers_sum -= digit else: break return numbers_sum print(some_function(n))
Program needs to print the sum of numbers that are not found in the input. I covered the scenario when numbers are not repeating and for this scenario if the input is 234567890 output is 1 . But don't have an idea for scenario when numbers are repeating.Etc. if the input is 22334567890 or 223344556677889900 output still needs to be 1 but it's not. P.S. I know 0 doesn't make difference because we are doing with - and +. |

As I was making the pop-up message box which would appear on clicking different images, I saw that it was showing same messages for different products even after giving different description for each one of them. I don't know JavaScript much but some code must be added there I guess. Here is the code- $(".modal-trigger").click(function(e){ e.preventDefault(); dataModal = $(this).attr("data-modal"); $("#" + dataModal).css({"display":"block"}); // $("body").css({"overflow-y": "hidden"}); //Prevent double scrollbar. }); $(".close-modal, .modal-sandbox").click(function(){ $(".modal").css({"display":"none"}); // $("body").css({"overflow-y": "auto"}); //Prevent double scrollbar. });
.modal, .modal-box { z-index: 900; } .modal-sandbox { position: fixed; width: 100%; height: 100%; top: 0; left: 0; background: transparent; } .modal { display: none; position: fixed; width: 100%; height: 100%; left: 0; top: 0; background: rgb(0,0,0); background: rgba(0,0,0,.8); overflow: auto; } .modal-box { position: relative; width: 80%; max-width: 920px; margin: 100px auto; animation-name: modalbox; animation-duration: .4s; animation-timing-function: cubic-bezier(0,0,.3,1.6); } .modal-header { padding: 20px 40px; background: #546E7A; color: #ffffff; } .modal-body { background: #ECEFF1; padding: 60px 40px; } /* Close Button */ .close-modal { text-align: right; cursor: pointer; } /* Animation */ @-webkit-keyframes modalbox { 0% { top: -250px; opacity: 0; } 100% { top: 0; opacity: 1; } } @keyframes modalbox { 0% { top: -250px; opacity: 0; } 100% { top: 0; opacity: 1; } } .modal-trigger, button { top: 100%; left: 100%; padding: 20px 40px; background: transparent; color: #ffffff; border: 1px solid #ffffff; text-decoration: none; } .modal-trigger { position: absolute; top: 100%; left: 100%; -webkit-transform: translate(-50%, -50%); -ms-transform: translate(-50%, -50%); -o-transform: translate(-50%, -50%); transform: translate(-50%, -50%); transition: ease .2s; } button { border: 1px solid #333333; outline: none; color: #333333; } .modal-trigger:hover { padding: 20px 60px; }

| how to distinguish between no time and midnight in COleDateTime class Posted: 12 Dec 2021 07:44 AM PST We use the DD-MM-YYYY HH:mm:ss date and time format API between frontend and backend. However, there are cases that backend gets only the date since time wasn't selected at the frontend side. The GET call parameter will look like this: startTime=16-11-2021
At the backend side, we use the COleDateTime class in order to parse the date and time. The problem is that the time in the case above is initialized to 00:00:00 when actually no time is sent. I need a way to distinguish between no time sent and midnight as the actual time is significant in our system and there is a big difference between no time sent and midnight. It seems that the ParseDateTime function expects to get a flag in its second parameter VAR_TIMEVALUEONLY to Ignore the date portion during parsing. So for that, I need to implement a parse function in order to know if I got the time or not where it is expected that the ParseDateTime function would be set as an undefined time like -1 when no time is sent. Is there a way to distinguish between no time to midnight in COleDateTime class? If not, maybe you have another way I can use public libraries like <chrono> which could solve my problem? |

| Install gcc-arm-none-eabi or arm-none-eabi-gcc on android with termux Posted: 12 Dec 2021 07:44 AM PST I need to install arm-none-eabi-gcc / gcc-arm-none-eabi ARM compiler on android in order to convert C++ to ASM (M3 Cortex), on android device with AArch64 architecture (not rooted) using third party Termux app as terminal and linux enviroment emulator for that arm compiler. Using Termux with it's API I'm planning to create a simple android app which will do the convertion task easily, by running arm compiler from shell with parameters to convert C++ to ASM. I tried many times following online articles to build the arm compiler but could not be able to install that package. For example: $ sudo apt-get remove binutils-arm-none-eabi gcc-arm-none-eabi $ sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa $ sudo apt-get update $ sudo apt-get install gcc-arm-none-eabi $ sudo apt-get install gdb-arm-none-eabi
Because, I use Termux as terminal and linux enviroment emulator, I fail to build the arm compiler everytime. How to install that arm compiler on android (posible using termux), if all I want is to run the compiler from shell with parameters to get C++ converted to ASM (M3 Cortex) arm-none-eabi-gcc -O2 -mthumb -c test.c -o test.o

| ASP.Net Core 5 MVC Bootstrap Render Div When Screen Smaller Than X Width Posted: 12 Dec 2021 07:44 AM PST I am creating an ASP.Net Core 5 App with Bootstrap 5. I want to conditionally render the Header elements based on screen width. 
This is the header when the browser is larger, like on a laptop. Right now, everything collapses into the bootstrap hamburger menu. What I want to happen is for the Hello David, Logout, and Cart Info button to be placed to the right of the My Shopping Cart Logo, and for the Home, Privacy, and Search to go to the hamburger menu. Here is the current view when everything is collapsed. 
And what I want to accomplish is something like 
But now that I am looking at it, maybe I will get rid of the Log Out button, and make logout part of the Hello David drop down. So in order to accomplish something like this, I need to check for when the screen is smaller than x width...Whenever Bootstrap collapses everything down. I have done lots of Googling, and I see posts about media queries, but I get the sense that media queries are for something like React or Angular. How would I accomplish this in ASP.Net Core 5 MVC? Here is my code. <nav class="navbar navbar-expand-lg navbar-light bg-light"> <div class="container-fluid"> <a class="navbar-brand" asp-controller="Products" asp-action="Index"><img src="@(Configuration.GetValue<string>("StorageContainerURL"))/store-logo.png" ) class="img-fluid" style="max-height:75px;width:auto" alt="Alternate Text" /></a> @*I want to render*@ @* <partial name="_Identity.cshtml" /> @*This is the Hello David and Logout Button <ul class="navbar-nav mb-2 mb-lg-0"> @await Component.InvokeAsync("ShoppingCartSummary") @*This is the Shopping Cart Button" </ul> *@ @*if the screen is < X width*@ <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarSupportedContent"> <ul class="navbar-nav me-auto mb-2 mb-lg-0"> <li class="nav-item"> <a class="nav-link text-dark" asp-area="" asp-controller="Products" asp-action="Index">Home</a> </li> <li class="nav-item"> <a class="nav-link text-dark" asp-area="" asp-controller="Home" asp-action="Privacy">Privacy</a> </li> @if (!User.IsInRole("Seller")) { <li class="nav-item"> <a class="nav-link text-dark" asp-area="" asp-controller="Account" asp-action="EditProfile">Become a Seller</a> </li> } </ul> <form class="d-flex" asp-controller="Products" asp-action="Filter"> <input name="searchString" class="form-control me-1" type="search" placeholder="Search for a product..." aria-label="Search"> <button class="btn btn-outline-success me-2" type="submit">Search</button> </form> <partial name="_Identity.cshtml" /> @*This is the Hello David and Logout Button*@ <ul class="navbar-nav mb-2 mb-lg-0"> @await Component.InvokeAsync("ShoppingCartSummary") @*This is the Shopping Cart Button*@ </ul> </div> </div> </nav>
Edit: I figured it out. I wanted to show the answer, but I do not want to take credit for the answer. This will only be visible on xs, sm, and md screens. <div class="d-block d-lg-none">
This will only be visible on lg and larger screens. <div class="d-none d-lg-block">
This is applicable to Bootstrap 5. See Bootstrap 5 Hiding Elements |
