Im using python 3.6 with the youtube_dl module on Ubuntu 18.04.
Im trying to download Youtube videos with aria2c.
These are my option settings:
import youtube_dl
opts = {
'format': "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best",
'external-downloader' : 'aria2c',
'external-downloader-args' : "--max-connection-per-server=16 --dir=/home/downloads",
}
ydl=youtube_dl.YoutubeDL(opts)
ydl.download([f"https://www.youtube.com/watch?v={ytId}"])
But it still uses the built-in downloader.
opts = {
'format': "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best",
'external_downloader' : 'aria2c',
'external_downloader_args' :['--max-connection-per-server=16','--dir=/home/downloads'],
}

I want to use pdfMake in deno and not host the pdfMake files and vfs_fonts on my server, by using a CDN line CDNJS or esm.sh.
I have the following code in the to of my app.js file:
import pdfMake from "https://esm.sh/pdfmake"
import * as pdfFonts from "https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.2.4/vfs_fonts.min.js"
but I get the following errors:
[!] [#0] starting `deno run -A app.js`

I am not sure how to import or load the vfs_fonts from the CDN. Please note that my aim is to use a CDN for getting pdfMake and it's fonts.
I've changed the app.js file so that I only load the pdfmake from the CDN. I then load the fonts seperatly from the CDN into the pdfMake object:
import pdfMake from "https://esm.sh/pdfmake"
pdfMake.fonts = {
Roboto: {

I'm quite new to Nix and I'm trying to create a very simple shell.nix script file.
Unfortunately I need an old package: mariadb-10.4.21. After reading and searching a bit I found out that version 10.4.17 (would've been nice to have the exact version but I couldn't find it) is in channel nixos-20.09, but when I do
$ nix-shell --version
nix-shell (Nix) 2.5.1
$ cat shell.nix
let
pkgs = import <nixpkgs> {};
# git ls-remote https://github.com/nixos/nixpkgs nixos-20.09
pkgs-20_09 = import (builtins.fetchGit {
name = "nixpks-20.09";
url = "https://github.com/nixos/nixpkgs";
ref = "refs/heads/nixos-20.09";
rev = "1c1f5649bb9c1b0d98637c8c365228f57126f361";
}) {};
in
pkgs.stdenv.mkDerivation {
pname = "test";
version = "0.1.0";
buildInputs = [
pkgs-20_09.mariadb
];
}
$ nix-shell
it just waits indefinitely without doing anything. But if I do
$ nix-shell -p mariadb -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/1c1f5649bb9c1b0d98637c8c365228f57126f361.tar.gz

[nix-shell:~/Playground]$ mariadb --version
mariadb Ver 15.1 Distrib 10.4.17-MariaDB, for Linux (x86_64) using readline 5.1
it works perfectly.
What am I doing wrong in the script for it to halt?
EDIT: I got a bit more info by running
$ nix-shell -vvv
[...]

Is it me or it seems like it's trying to fetch from two different sources? As far as I understood all three url, rev and ref are needed for git-fetching, but it looks like if it's splitting them.
EDIT2: I've been trying with fetchFromGitHub
pkgs-20_09 = import (pkgs.fetchFromGitHub {
name = "nixpks-20.09";
owner = "nixos";
repo = "nixpkgs";
rev = "1c1f5649bb9c1b0d98637c8c365228f57126f361";
sha256 = "0f2nvdijyxfgl5kwyb4465pppd5vkhqxddx6v40k2s0z9jfhj0xl";
}) {};
and fetchTarball
pkgs-20_09 = import (builtins.fetchTarball "https://github.com/NixOS/nixpkgs/archive/1c1f5649bb9c1b0d98637c8c365228f57126f361.tar.gz") {};
and both work just fine. I'll use fetchFromGitHub from now on but it'd be interesting to now why fetchGit doesn't work.
I have some difficulties to apply a css file to my dash app when using cx_freeze. If I run python app.py the layout is properly applied, however not if I am executing the .exe generated by cx_freeze. Then the default html layout is displayed. The css and the image appear in the same directory where the .exe is located.
This is how my setup.py looks like.
from setuptools import find_packages
from cx_Freeze import setup, Executable
options = {
'build_exe': {
'includes': [
'cx_Logging', 'idna', 'idna.idnadata'
],
'packages': [
'asyncio', 'flask', 'jinja2', 'dash', 'plotly', 'waitress'
],
'excludes': ['tkinter'],
'include_files': [
'assets/logo.jpg', 'assets/style.css'
],
}
}
executables = [
Executable('server.py',
base='console',
targetName='dash_app.exe')
]
setup(
name='BI_Report',
packages=find_packages(),
version='0.0.1',
description='rig',
executables=executables,
options=options
)
To load the external files I use a helper function as suggested here:
def find_data_file(filename):
if getattr(sys, 'frozen', False):
# The application is frozen
datadir = os.path.dirname(sys.executable)
else:
# The application is not frozen
# Change this bit to match where you store your data files:
datadir = os.path.dirname(__file__)
return os.path.join(datadir, filename)
app = dash.Dash(__name__,
assets_folder=find_data_file('assets/'))
I am using:
Python 3.7.6
dash 1.9.1
cx-freeze 6.1
Any help much appreciated!

Looks like you are using an very old version of the CorDapp template. Your build.gradle says Corda version 3.3
Whereas, we are currently 4.4 right now. Please download a copy of the latest template and work on it. https://github.com/corda/cordapp-template-java
Two related questions:
1. How does one install R and selected packages in the configuration.nix?
2. How does one add packages not only from CRAN but also from Gitub or at least locally stored?
In the wiki you will find instructions like these to install R packages. https://github.com/NixOS/nixpkgs/blob/master/doc/languages-frameworks/r.section.md . Have it working when using nix-shell but I'm stuck while trying to do the installation from configuration.nix.
Regarding building R packages and I have found this example regarding building packages:
let
pkgs = import <nixpkgs> {};
buildRPackage = import <nixpkgs/pkgs/development/r-modules/generic-builder.nix> pkgs.R;
in
with pkgs.rPackages;
{
foobar = buildRPackage {
name = "your-package-name-1.0";
src = ./.;
propagatedBuildInputs = [/* required dependencies go here */];
};
}
The command "nix-build . -A foobar" would then compile it.
But would like to run all from configuration.nix in order to the machine configuration in one place.
Ok, with the help of Bulats pointer above I managed to find a solution. A complete example was found here: https://github.com/NixOS/nixpkgs/issues/44290
For future reference here is one way of adding r packages both from CRAN and Github inline in configuration.nix:
environment.systemPackages = with pkgs;
[(pkgs.rWrapper.override {
packages = with pkgs.rPackages; let
llr = buildRPackage {
name = "llr";
src = pkgs.fetchFromGitHub {
owner = "dirkschumacher";
repo = "llr";
rev = "0a654d469af231e9017e1100f00df47bae212b2c";
sha256 = "0ks96m35z73nf2sb1cb8d7dv8hq8dcmxxhc61dnllrwxqq9m36lr";};
propagatedBuildInputs = [ rlang knitr];
nativeBuildInputs = [ rlang knitr ];};
in [knitr
rlang
llr
tidyverse

devtools];})
pkgs.postgresql
pkgs.isync
pkgs.msmtp
pkgs.notmuch
gnupg
