| electron-builder error related to node-gyp Posted: 27 Oct 2021 07:49 AM PDT I'm having an error whenever I try building my app with Electron. I didn't have this issue until last week or so, It was working fine before, it suddenly stopped working. I didn't understand the issue so I reinstalled my OS and everything on the computer, but it didn't change anything. I found some messages on the terminal telling me to install python, then VSCode with C++ for desktop applications, I did, then the error changed and I don't see any way to fix it any further. This is my package.json, im running 'npm run build': { "name": "reactron", "version": "0.1.0", "private": true, "dependencies": { "@szhsin/react-menu": "^1.8.0", "brace": "^0.11.1", "electron-is-dev": "^1.1.0", "fs-extra": "^10.0.0", "gpu.js": "^2.11.4", "gsap": "^3.4.0", "howler": "^2.1.3", "jsoneditor": "^9.5.6", "jsoneditor-react": "^3.1.1", "node-sass": "^4.14.1", "react-draggable": "^4.4.3", "react-json-editor-ajrm": "^2.5.13", "react-xarrows": "^1.5.2", "vanilla-picker": "^2.11.2" }, "main": "public/electron.js", "homepage": "./", "scripts": { "react-start": "react-scripts start", "react-build": "react-scripts build", "react-test": "react-scripts test --env=jsdom", "react-eject": "react-scripts eject", "electron-build": "electron-builder", "build-electron": "mkdir build/src && robocopy electron build/electron /S & robocopy src/shared build/src/shared /S", "release": "npm run react-build && electron-builder --publish=always", "build": "npm run react-build && npm run electron-build", "start": "concurrently \"cross-env BROWSER=none npm run react-start\" \"wait-on http://localhost:3000 && electron .\"" }, "eslintConfig": { "extends": "react-app" }, "browserslist": { "production": [ ">0.2%", "not dead", "not op_mini all" ], "development": [ "last 1 chrome version", "last 1 firefox version", "last 1 safari version" ] }, "devDependencies": { "@reduxjs/toolkit": "^1.3.6", "@testing-library/jest-dom": "^4.2.4", "@testing-library/react": "^9.5.0", "@testing-library/user-event": "^7.2.1", "concurrently": "^5.1.0", "cross-env": "^7.0.2", "electron": "^8.1.1", "electron-builder": "^22.13.1", "electron-packager": "^14.2.1", "electron-react-devtools": "^0.5.3", "react": "^16.13.0", "react-dom": "^16.13.0", "react-indiana-drag-scroll": "^1.8.0", "react-redux": "^7.2.0", "react-scripts": "^3.4.3", "redux": "^4.0.5", "wait-on": "^4.0.1" }, "build": { "asar": false } }

Does anyone know how to solve this?  |
| "locationError.config()" returns a NameError in my Python code Posted: 27 Oct 2021 07:49 AM PDT I'm making this simple Youtube downloader software, but locationError is underlined in red and when I run the code it retuns this error: locationError.config(text=Folder_Name, fg="green") NameError: name 'locationError' is not defined
However, when I copy and paste the same code (the whole code, not just the block that includes locationError line) from the tutorial everything works fine and no errors are given at all. Code: from tkinter import * from tkinter import ttk from tkinter import filedialog from pytube import YouTube Folder_Name = "" def open_location(): global Folder_Name Folder_Name = filedialog.askdirectory() if (len(Folder_Name) > 1): locationError.config(text=Folder_Name, fg="green") else: locationError.config(text="Please specify a folder!", fg="red") def download_youtube(): choice = quality.get() url = url_box.get() if (len(url) > 1) and "youtube".encode() in url: url_error.config(text="") yt = YouTube(url) if choice == choices[0]: select = yt.streams.get_highest_resolution() elif choice == choices[1]: select = yt.streams.filter(progressive=True,file_extension='mp4').last() elif choice == choices[2]: select = yt.streams.filter(only_audio=True).first() else: url_error.config(text="Paste link again", fg="red") select.download(Folder_Name) url_error.config(text="Download completed!") root = Tk() root.title("Youtube Downloader") root.geometry("350x400") root.columnconfigure(0, weight=1) space = Label(text="") space.grid() url_label = Label(root, text="Enter URL of the video", font=("jost", 9, "bold")) url_label.grid() EntryVar = StringVar() url_box = Entry(root, width=50, textvariable=EntryVar) url_box.grid() url_error = Label(root, text="URL Error", fg="red", font=("jost", 9, "bold")) url_error.grid() space = Label(text="") space.grid() path_label = Label(root, text="Save the video file", font=("jost", 9, "bold")) path_label.grid() path_btn = Button(root, width=10,bg="green", fg="white", text="Choose Path", command=open_location) path_btn.grid() path_url = Label(root, text="Path Error", fg="red", font=("jost", 9, "bold")) path_url.grid() space = Label(text="") space.grid() quality_label = Label(root, text="Select quality", font=("jost", 9, "bold")) quality_label.grid() choices = ["Highest", "Lowest", "Audio"] quality = ttk.Combobox(root, values=choices) quality.grid() space = Label(text="") space.grid() space = Label(text="") space.grid() download_btn = Button(width=15, height=2, bg="green", fg="white", text="Download", font=("bold"), command=download_youtube) download_btn.grid() for i in range(0,2): space = Label(text="") space.grid() dev_label = Label(root, text="Developed by Totenkopf 💀", bg="black", fg="red", font=("jost", 11)) dev_label.grid() root.mainloop()

| Strange behaviour: if( takes boolean false Posted: 27 Oct 2021 07:48 AM PDT Hi I'm writing a firebase cloud function to send an email if the user wants to receive emails. The problem is, that with userData.notifications.emails true or false, it always sends the email. With false the log shows: Send Emails YES: false
if (userData?.notifications?.emails) { functions.logger.log('Send Emails YES: ' + userData.notifications.emails); admin.firestore().collection(`emails`).add({ to: email, message: { subject: subject, html: text, } }) } else { functions.logger.log('Don't send Email') }

| Gray the card on click in Bootstrap Posted: 27 Oct 2021 07:48 AM PDT A common function in infinite list is that, the item will be grayed after when we clicked on him. Can we get this effect with only HTML, CSS, JS, jQuery(on the user's side)? How it works? 1.) the user clicks on the card element  2.) When pressed, class text-muted is added to the card element, causing it to be grayed out as below  The simplest example of code in bootarap looks like this: {% for obj in objects %} <a href="/detail/id/" target="_blank"> <div class="card" id="card{{ obj.id }}"> <!--..content card..--> </div> </a> {% endfor %}

Parsing the header according to RFC 2326 10.12 as_bitstream = BitStream(socket.recv(4096)) # from bitstring import BitStream if as_bitstream.read(8) == "0x24: # check if package start with $ (0x24) channel_identifier = as_bitstream.read("uint:8") length = as_bitstream.read("uint:16") version = as_bitstream.read("uint:2") padding = as_bitstream.read("uint:1") extension = as_bitstream.read("uint:1") csrc_count = as_bitstream.read("uint:4") marker = as_bitstream.read("uint:1") payload_type = as_bitstream.read("uint:7") sequence_number = as_bitstream.read("uint:16") timestamp = as_bitstream.read("uint:32") ssrc = as_bitstream.read("uint:32")
Parsed fields looks good to me and have correct values: - payload = 96
- version = 2
- sequence number is increasing.
Two questions: - Are remeaing bytes after ssrc location the rtp payload if extension = 0 ?
- When a recived data starts with $ it is a RTP packed, I also recive data without a starting $ what is this ?
- Should every rtp packed include NAL Units?
Also I read this post Link but I am currios why there are no NAL units after the RTP Header. Example RTP Package Dump (Google Drive) I am new to these topic and maybe anyone can help me. Thank you  |
| Is it possible use socat to open an existing tun device instead of creating a new one? Posted: 27 Oct 2021 07:48 AM PDT It is known that socat can create a tun device and open it to relay. But I wonder how can I use it to relay an existing tun interface? The tun0 is created by other script.  |
| flutter remove tab bar for specific pages Posted: 27 Oct 2021 07:48 AM PDT Main Page (CategoryViewDetail) generating Tabbar and BottomNavigationBar and parsing JSON to NewsView Page. My BottomNavigationBar has got 4 buttons and for 4th button I would like to remove the TabBar. This is again NewsView page but with different widget.id. I would like to remove TabBar only for 4th button. NewsView does not have any controller, it is only generating content according to widget.id. Is there any way to do this?  |

| Rewrite TypeScript property to be optional via type merging Posted: 27 Oct 2021 07:48 AM PDT Is there a single way to make property of type optional via intersection for example? I was thinking that if we have type T: type T = { x: string y: string z: string }
then: T & { z?: string }
would rewrite z property of T to become optional. But this is not the case. How can I achieve, so z will be optional property? Thanks.  |
| Splitting class definition in .h and .cpp file [duplicate] Posted: 27 Oct 2021 07:48 AM PDT following standards, I splitted class definition in two files, these are they fraction.h #ifndef FRACTION_H #define FRACTION_H #include <string> #include <cmath> #include <climits> using std::string; using std::log10; using std::ceil; class fraction { private: int __max_arr_len = (int)ceil(log10(__LONG_MAX__)); long numerator; long denomenator; string convertion(long _num); public: void reduce(); inline void set_numerator(long _new); inline void set_denominator(long _new); inline long get_numerator(); inline long get_denominator(); inline double get_fraction(); inline string get_str_fraction(); fraction(long _num, long _den); };
