how to make a Function Call? Posted: 27 Jun 2021 09:46 AM PDT I have a problem when executing my function, I have been putting it in the main but it does not execute (it does not mark any error either) and I have been trying to execute it in the previous function (Column) but it does not allow me to execute it unless it is within the first for, otherwise it still cannot be executed, I have implemented an if condition, so that the call of the function is not repeated the n times that lasts the for cycle but I have realized that this condition generates that the matrix M void Renglon(){ int etapa; int z=0; for(i=0; i <= N-1; i++) { for(n=0; n< N; n++){ x[n] = MC[i][n]; init_bro(); init_W(); ordena_ent(); for(etapa=1; etapa <= nbits; etapa++){ combina(etapa); } } z=z+1; printf("\n\n Salida = (%d) ", z); for(m=0; m<N; m++) printf("\n x[%d] = %.2f + %.2f j", m, creal(mcombina[m][3]), cimag(mcombina[m][3])); //printf("\n x[%d,%d] = %.2f + %.2f j", m,i, creal(MC[m][7]), cimag(MC[m][7])); } } void Columna(){ int etapa; int g = 0; int z=0; for(n=0; n <=64 ; n+=8, j=1+j) { for(i=0; i <= N-1; i++){ x[i] = (double)data[n+i][0] + data[n+i][1]*I; init_bro(); init_W(); ordena_ent(); } for(etapa=1; etapa <= nbits; etapa++){ combina(etapa); } for(i=0; i <= N-1; i++) { MC[i][j] = mcombina[i][3]; //MT[i][j]=MC[i][1]; g=g+1; } if(g==8){ Renglon(); } } } int main(int argc, char const *argv[]) { /* code */ if (argc < 3){ printf("Please specify the CSV file as an input.\n"); exit(0); } char row = atoi(argv[1]); char col = atoi(argv[2]); char fname[256]; strcpy(fname, argv[3]); data = (double **)malloc(row * sizeof(double *)); for (int i = 0; i < row; ++i){ data[i] = (double *)malloc(col * sizeof(double)); } int etapa; read_csv(row, col, fname, data); Columna(); Renglon(); return 0; }

Pyinstaller not working well with ttkbootstrap library Posted: 27 Jun 2021 09:46 AM PDT I have a simple GUI which I designed with tkinter & ttkbootstrap. Everything works fine when I run the script with my IDE. Also, The main.exe file is created successfully with Pyinstaller by using this command: pyinstaller.exe --onefile main.py.

CSS accordion opens on click, but won't close! Help would be appreciated Posted: 27 Jun 2021 09:46 AM PDT I've got a pure CSS accordion partly working on my site. It opens on click, however for some reason it won't close when clicked again. I've tried lots of tweaks to try and get this sorted but nothing's helped so I'd love to know if anybody here could work it out for me. The exact code I'm using is here on CodePen and pasted below. .gohere-accordion { margin-top: 7px; margin-bottom: 7px; margin-left: 4px; margin-right: 15px; width: 99%; color: #484848; } .gohere-accordion input { display: none; } .gohere-box { position: relative; background: white; height: 64px; transition: all .15s ease-in-out; color: #484848; } .gohere-box::before { content: ''; position: absolute; display: block; top: 0; bottom: 0; left: 0; right: 0; pointer-events: none; box-shadow: 0 -1px 0 #e5e5e5,0 0 2px rgba(0,0,0,.12),0 2px 4px rgba(0,0,0,.24); } gohere-header.box { background: #00BCD4; color: #484848; z-index: 100; cursor: initial; box-shadow: 0 -1px 0 #e5e5e5,0 0 2px -2px rgba(0,0,0,.12),0 2px 4px -4px rgba(0,0,0,.24); } gohere-header .gohere-box-title { margin: 0; font-weight: normal; font-size: 16pt; color: #484848; cursor: initial; } .gohere-box-title { width: calc(100% - 40px); height: 64px; line-height: 64px; padding: 0 20px; display: inline-block; cursor: pointer; color: #484848; -webkit-touch-callout: none;-webkit-user-select: none;-khtml-user-select: none;-moz-user-select: none;-ms-user-select: none;user-select: none; } .gohere-box-content { width: calc(100% - 40px); padding: 30px 20px; font-size: 11pt; color: #484848; color: rgba(0,0,0,.54); display: none; } .gohere-box-close { position: absolute; height: 64px; width: 100%; top: 0; left: 0; cursor: pointer; display: none; } input:checked + .gohere-box { height: auto; margin: 16px 0; box-shadow: 0 0 6px rgba(0,0,0,.16),0 6px 12px rgba(0,0,0,.32); } input:checked + .gohere-box .gohere-box-title { border-bottom: 1px solid rgba(0,0,0,.18); } input:checked + .gohere-box .gohere-box-content, input:checked + .gohere-box .gohere-box-close { display: inline-block; } .arrows section .gohere-box-title { padding-left: 44px; width: calc(100% - 64px); } .arrows section .gohere-box-title:before { position: absolute; display: block; content: '\203a'; font-size: 18pt; left: 20px; top: -2px; transition: transform .15s ease-in-out; color: rgba(0,0,0,.54); } input:checked + section.gohere-box .gohere-box-title:before { transform: rotate(90deg); } <nav class="gohere-accordion"><!-- THEN ONE OF THESE PER SINGLE ACCORDION --><input id="cb1" name="gohere-accordion" type="radio" /> <section class="gohere-box"><label class="gohere-box-title" for="cb1">This is a frequently asked question - opens, but won't close!</label> <div class="gohere-box-content">Now it's open, how can I make it close on click?</div> </section> </nav>

Resolving a promise in React Posted: 27 Jun 2021 09:46 AM PDT I'm new to Front end dev and am facing this scenario where I'm trying to do some action after a promise (from making an API call) is resolved. This is the code snippet. <api-call> .then((res) => { // promise resolving code }); The expected structure of the API response: { "success": true, "message": "Message Text" } When running the application, the API returns the specified response (shown in Network response), but while inspecting the res object doesn't hold the same data. The response is { "success": false "message": undefined } The promise is resolved and the corresponding block is executed but raises errors due to incorrect response. I tried using an await before the API call, but it still doesn't work. Am I missing something else here?

anonymize rdbms datas, keeping key relations Posted: 27 Jun 2021 09:45 AM PDT Is there a "ready-to-use" method to anonymize datas, but keeping relations between keys ? For example, I have : Table #1 user code zip code ztxp15 45789 And : Table #2 user code order date ztxp15 2021-06-27 06:22pm I want it anonymized as : user code zip code xvdf65 32165 And : Table #2 user code order date xvdf65 2021-06-27 06:22pm This would need : a bijective function that transform a data, keeping its format ([a-z]{4}[0-9]{2}), generating the same value, according a passphrase for example. In this way, unicity will be kept, format too, etc. But maybe I miss something. I think that this problematic is very common so I am looking for previous work about it.

React typescript interface only one of two required Posted: 27 Jun 2021 09:45 AM PDT I was wondering how I can require one of the properties in the interface. I don't want to require both HideBelow and HideAbove but only one of them. How would I go about implementing that? There needs to be either below={HideBelow} or below={HideAbove} in the component. <Example below={HideBelow} /> <Example below={HideAbove } /> interface TableContentProps { Data?: any; HideType: "above" | "below" | "none"; HideBelow?: "sm" | "md" | "lg" | "xl"; HideAbove?: "sm" | "md" | "lg" | "xs"; }

Is it not correct to do api call without useEffect? Posted: 27 Jun 2021 09:44 AM PDT I want to do an api call after a button is clicked in react.But I have read that to do async tasks, we use useEffect. So is it okay to not use useEffect and do an api call without it? I think that without using useEffect an api call would block the render. So,What is the correct way to do an api call if it has to be done on Click?

How to use the ISEMPTY function Posted: 27 Jun 2021 09:45 AM PDT I am learning SQL and using Myworkbench to do so. The error is pointing to the isempty function. Where am I going wrong? SELECT a.ParcelID, a.PropertyAddress, b.ParcelID, b.PropertyAddress, isempty(a.propertyAddress,b.propertyAddress) FROM portfolioproject.nashvillehousing a join nashvillehousing b on a.ParcelID = b.ParcelID and a.UniqueID <> b.UniqueID where a.PropertyAddress = '';

Error in mysql #1241 — The operand must contain 1 columns. How do I make an alternative working request? Posted: 27 Jun 2021 09:46 AM PDT I understand that in the IN operator, and more precisely in SELECT, it is impossible to select two columns. Could you write an alternative of the same query or fix this one. SELECT * FROM `board` WHERE moder=0 AND activ=0 AND id_akk IN (SELECT user_id_to, user_id_from FROM `podpiski` WHERE user_id_from='38')

How to create a object with numbers 500 at 524 without going one by one Posted: 27 Jun 2021 09:47 AM PDT I want to create and then replace in a string, would it be able to appear in the object 500 up to 524 without having to go from 1 to 1? I hope it's understandable with the examples const numbers = { 500: "20" } console.log(user.list.map(list => numbers[user.points])) e.g.: const numbers = { 500 at 524: "20", 600 at 650: "25" } way that works, but it would be too much big: const numbers = { "500": "20", "501": "20", "502": "20", "503": "20", (...) } if this is not possible, let me know that I will delete the question.

Why is there no difference between variables in Python? Posted: 27 Jun 2021 09:44 AM PDT I am a beginner in Python and just starting to learn from home. I did an exercise on creating a list containing friends and print them one by one. Then, I need to print them one by one including a message. The text of each message should be the same, but each message should be personalized with the person's name. So, this is the first code: names = ['John','Ben','Daniel','Nathan'] greetingJohn = f"Good morning {names[0]}." print(greetingJohn) greetingBen = f"Good morning {names[1]}." print(greetingBen) greetingDaniel = f"Good morning {names[2]}." print(greetingDaniel) greetingNathan = f"Good morning {names[3]}." print(greetingNathan) This is the second code: names = ['John','Ben','Daniel','Nathan'] greeting = f"Good morning {names[0]}." print(greeting) greeting = f"Good morning {names[1]}." print(greeting) greeting = f"Good morning {names[2]}." print(greeting) greeting = f"Good morning {names[3]}." print(greeting) The output is the same for both: Good morning John. Good morning Ben. Good morning Daniel. Good morning Nathan. So, I am confused why is there no difference between the 'greeting{name}' and only 'greeting'? Hopefully, you can answer my curious beginner question.

How can I get a YouTube video upload date with Selenium in Python?

If anyone knows where the problem is, please help me.

Match every row in a dataframe to each row in another dataframe in r Posted: 27 Jun 2021 09:46 AM PDT This might be a simple question, but I couldn't seem to find an obvious solution. I have two data frames, df1 with 64 rows, and df2 with 662,343 rows. I essentially want to left join df1 to df2, where every row in df1 is mapped to each row in df2, so that I end up with 42,389,952 rows. df1 and df2 might look like this respectively: df1: | Cancer | ID | |---------------------|------------------| | Sarcoma | 3435 | | Leukemia | 4465 | df2: Gene TP53 new data frame : Cancer ID Gene Sarcoma 3435 TP53 Leukemia 4465 TP53 Thanks in advance for any help!

Confusion about different meanings of "HighMem" in Linux Kernel Posted: 27 Jun 2021 09:46 AM PDT I'm trying to understand what "highmem" means but I've seen it used in two different ways and I want to know if one or both are correct. The two definitions I've gleaned are: Highmem refers to a specific situation in 32 bit systems, where the system could fit more than 4GB of RAM but 32 bits only allowed the kernel to address 4GB memory directly, so any memory above 4GB needed to use Physical Address Extensions (PAE) and was called "highmem". When I see this version of high memory discussed, usually it's mentioned that 64 bit systems no longer have this problem; they can address their physical memory fully so no notion of "highmem" is needed (see 1, 2, 3). My own 64-bit system doesn't show any highmem memory in /proc/zoneinfo or in free -ml. Highmem is used to describe the virtual memory address space that is for user-space. This is in contrast with lowmem, the address space that is used for the kernel and is mapped into every user-space program's address space. Another way I've seen this phrased is with the names zone_highmem (highmem) and zone_normal (lowmem). For instance, in the 32-bit system "3/1" user/kernel memory split, the 3GB used for user space would be considered high memory (see 4, 5, 6, 7). Is one definition more correct than another? Are both correct but useful in different situations (i.e. definition 1 referring to physical memory, definition 2 referring to virtual memory)?

Python - Fastest way to find all perfect squares in a given large number range Posted: 27 Jun 2021 09:45 AM PDT I am trying to write a method to get all the perfect squares in a given range in Python. A large range like between 2621163 and 520001400002. Now obviously iterating through the range and checking if a number is perfect like so def is_square(n): return math.sqrt(n).is_integer() and then printing it is stupid for large ranges (works great for small ranges) and will take forever. I am wondering if there is any Python magic or mathemagic (say a modified Diophantine equation) that I can leverage for this purpose. EDIT: Also I am using Python 3.X so I can use large integers.
