QUESTION
I'm using ffmpeg as:
...ANSWER
Answered 2022-Apr-07 at 22:14I think you are quite confused about the crop filter options. Here are the descriptions of the first 4 options:
w, out_w The width of the output video. It defaults to iw. This expression is evaluated only once during the filter configuration, or when the ‘w’ or ‘out_w’ command is sent.
h, out_h The height of the output video. It defaults to ih. This expression is evaluated only once during the filter configuration, or when the ‘h’ or ‘out_h’ command is sent.
x The horizontal position, in the input video, of the left edge of the output video. It defaults to (in_w-out_w)/2. This expression is evaluated per-frame.
y The vertical position, in the input video, of the top edge of the output video. It defaults to (in_h-out_h)/2. This expression is evaluated per-frame.
- If you want to halve the width, then the first option must be
in_w/2regardless of which side to crop from. - Height is unchanged, so always use
in_h - To crop from left, x offset must match the width, so
in_w/2. To crop from right, no pixels are removed on the left edge, so must be0. - Because no rows are removed, use
y = 0.
So to summarize:
- Crop the left edge:
crop=in_w/2:in_h:in_w/2:0 - Crop the right edge:
crop=in_w/2:in_h:0:0
QUESTION
Save this code as a shell script and run it. The code should report the File is not a zip file error.
ANSWER
Answered 2022-Apr-01 at 07:31It seems that this is caused by the GitPython's bug. It truncated the last \n of the output of git show and made the file invalid.
I changed the code to use subprocess.Popen and ZipFile succeeded.

Here's a simple modelling workflow using the palmerpenguins dataset:
...ANSWER
Answered 2022-Mar-23 at 20:49When you use
last_fit()you fit to the training data and evaluate on the testing data. If you look at the output oflast_fit(), the metrics and predictions are from the testing data, while the fitted workflow was trained using the training data. You can read more about using the test set.You have surfaced a bug in how we handle tuning engine-specific arguments in parsnip extension packages. I know this is inconvenient for you, but thank you for the report!
QUESTION
I am trying to add p-values to my boxplot using ggboxplpot, but it seems stat_compare_means() doesn't work when I have multiple y = values.
here is the sample code from palmerpenguin dataset
ANSWER
Answered 2022-Jan-30 at 10:44The issue is that ggboxplot returns a list of ggplots, one for each of your variables. Hence adding + stat_compare_means() to list won't work but instead will return NULL.
To add p-values to each of your plots have to add + stat_compare_means() to each element of the list using e.g. lapply:

ANSWER
Answered 2022-Jan-23 at 21:40This problem was due to noexec being set on /tmp. You can remove the restriction if you have the necessary privileges. Alternatively you can set the java.io.tmpdir in Android studio's VM options.
See Android kapt java.lang.UnsatisfiedLinkError Room for futher details.
QUESTION
I use two dropdown terminals in parallel: Yakuake and Guake.
When using Guake, the colors are way too dark, which makes much of the colored text unreadable because of insufficient contrast. The problem is most severe when displaying color #4 (dark blue) on black background (which is the default color ls displays directories with) or in Midnight Commander (default theme, dark blue background).
Yakuake displays all 16 colors correctly and the text is readable very well, the colored output of ls and Midnight Commander.
My OS is Linux 5.15.11-gentoo with plasma-5.88.0, gtk+-2.24.33 and gtk+-3.24.29. Here is my TERM setting in the environment:
...ANSWER
Answered 2022-Jan-15 at 22:32It turns out ls renders directories as bold font with the expectation that the text will appear in bright color. As explained by Guake developers this is non-standard behavior used with old terminals that did not supported fonts. Guake follows the ANSI standard and renders the text correctly.
The solution is to tweak the ls colors accordingly.

I'm cross-compiling for Raspberry Pi 4B using ARM's 10.3-2021.07 GCC toolchain (specifically this file uncompressed into ARMGCC). I'm also using the latest Raspberry OS image as sysroot (loop-mounted into RPISYSROOT). The host is an Ubuntu Xenial VM on a Windows host.
When using this compilation line (edited for readability, CFLAGS inspired by the Pi's /proc/cpuinfo, gentoo and GNU):

I want to display all links from https://www.gentoo.org/downloads/mirrors/ to the terminal.
Firstly, the script would wget the web page to a file called index.html, then a grep or sed command would simply display all the https://, http:// and ftp:// to the terminal.
Can someone help me with this command? I know it's simple, but I'm not really familiar with neither of these commands.
What i tried:
grep "" index.html
