I verified I had the latest version of the program, 2021.12.17.

To obtain further information on the error, I then ran the script with the --verbose option which showed me more details on the error.

The software, which is a command-line program to download videos from YouTube.com and other video sites, is maintained by ytdl-org and, on a Github webpage for the organization, I found issue #32247, ERROR: Unable to extract uploader id, which attributed the error to YouTube recently starting to add that "at sign", i.e., @, to URLs. jgmayer, who posted his comments and the solution just 3 hours before I encountered the problem posted the following solution:

The solution is to go to the file that you getting the error:
"/usr/local/Cellar/youtube-dl/2021.12.17/libexec/lib/python3.10/site-packages/youtube_dl/extractor/common.py"

Find the following line:

'uploader_id': self._search_regex(r'/(?:channel|user)/([^/?&#]+)', owner_profile_url, 'uploader id') if owner_profile_url else None,

Replace with the following:

'uploader_id': self._search_regex(r'/(?:channel/|user/|@)([^/?&#]+)', owner_profile_url, 'uploader id', default=None),

The poster indicated the relevant file is /usr/local/Cellar/youtube-dl/2021.12.17/libexec/lib/python3.10/site-packages/youtube_dl/extractor/common.py, but there is no /usr/local/Cellar directory on my system and running the script with the verbose option, showed the relevant code is on line 1,794 of /usr/local/lib/python3.6/site-packages/youtube_dl/extractor/youtube.py.

After making the suggested change, I was able to download a YouTube video with the program.

$ youtube-dl https://www.youtube.com/watch?v=JmSmjDngVXM

The updated youtube.py that can be used to replace the 2021.12.17 version in /usr/local/lib/python3.6/site-packages/youtube_dl/extractor/youtube.py.

# Jane Doe

You can include a comment to indicate who the IP address is associated with by prefixing the comment with a pound sign. The IP address should be followed by the word "RELAY" (you can put tabs in between the IP address and the word, if you like).

After changing the IP address, I rebuilt the access database with the makemap command. I then restarted Sendmail

# makemap hash /etc/mail/access </etc/mail/access
# service sendmail restart
Redirecting to /bin/systemctl restart  sendmail.service
#

I was then able to receive a test message she sent me. After updating the IP address, I may only have needed to restart Sendmail without running the makemap command first as I found the following at 19.3.2. Sendmail on a Red Hat website in reference to running the make all -C /etc/mail/ command (CentOS is derived from Red Hat Enterprise Linux):

All other generated files in /etc/mail (db files) will be regenerated if needed. The old makemap commands are still usable. The make command is automatically used whenever you start or restart the sendmail service.

While trying to set up Gradle, a software develpment build automation tool, on a Microsoft Windows 10 system, when I ran the gradle.bat file in the gradle bin directory, I saw the message below:

C:\Users\Jim\Downloads\gradle-7.5.1-bin\gradle-7.5.1\bin>gradle.bat

ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

C:\Users\Jim\Downloads\gradle-7.5.1-bin\gradle-7.5.1\bin>

I had installed Java with the Eclipse integrated development environment (IDE) previously and the java.exe executable was installed beneath the C:\Users\Jim\.p2\pool\plugins\org.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64_18.0.1.v20220515-1614\jre\ directory, so I created a JAVA_HOME environment variable pointing to that directory that applied to all accounts on the system. You can create a temporary JAVA_HOME environment variable for the account under which you are currently logged in from a command line interface (CLI) as noted at Running java from an Eclipse installation from the command line, but I wanted to create a permanent environment variable so I typed advanced system settings in the Windows "Type here to search" field and then clicked on View advanced system settings when I saw that listed.

Or you can select Paste Special and then click on the same icon that appears beneath Paste Values.

Once you've pasted the values that are in proper case, you can delete the column, e.g., B in this case, where the formulas are used.

Note: for addresses with Post Office boxes, any instance of "PO BOX" would be replaced with "Po Box," but you can use Excel's find and replace feature to search for all instances of "Po Box" and have it replace all those occurences with "PO Box".

I hadn't used PeaZip as a backup utility previously, but after reading about the program, I thought it would be well-suited to copy a directory containing about 37 GB of files on a Microsoft Windows Small Business Server (SBS) 2003 server to an external USB drive so that I could transfer the directory, which was shared over the network from the server, to the new 2022 server I was setting up to replace the outdated server. I downloaded the portable version, PeaZip Portable to a USB flash drive and when I started the program, I specified the external USB drive as the location for the .tar archive I wished to create, but when the PeaZip program showed it was progressing with the backup, I did not see the archive file on that external drive. After some time wondering whether PeaZip was actually creating the tar file, I wondered whether it might be creating a temporary file elsewhere, so from a command prompt, I checked the location Windows was using to store temporary files for the account I was using with echo %temp% and, when I checked that location, found a .tar.tmp file that PeaZip was using for the ongoing archive process. Unfortunately, that temporary file was in a directory on drive C that I knew did not have enough free space left to accomodate the archive file as PeaZip progressed further, so I had to delete a lot of files from that drive and mover others there so that I would not have to restart the archive process.

C:\>echo %temp%
C:\DOCUME~1\ADMINI~1.MAY\LOCALS~1\Temp

C:\>cd %temp%

C:\DOCUME~1\ADMINI~1.MAY\LOCALS~1\Temp>dir *.tar.tmp
 Volume in drive C has no label.
 Volume Serial Number is E88C-7773

 Directory of C:\DOCUME~1\ADMINI~1.MAY\LOCALS~1\Temp

08/12/2022  11:14 PM     5,569,092,608 Andy_2022-08-12.tar.tmp
               1 File(s)  5,569,092,608 bytes
               0 Dir(s)  33,934,786,560 bytes free

C:\DOCUME~1\ADMINI~1.MAY\LOCALS~1\Temp>

When PeaZip concluded the archive process, it moved the temporary file to the location I specified with the .tmp extension now removed, but now I know I need to ensure that the location specified with the Windows %temp% environment variable for a site has enough free space to accomodate the archive file before using PeaZip to create a .zip, .tar, etc. file archive.

For an introductory Java class I am taking, I installed the Eclipse integrated development environment (IDE) on a Microsoft Windows 10 system. In addition to compiling and running Java programs through the IDE, though, I wanted to compile Java programs using the Java compiler, javac.exe, and run them using java.exe from Windows' command-line interface (CLI). The installation process for Eclipse installed the javac.exe and java.exe executables in a user directory with a long directory path to those executables. Note: you should install the Eclipse IDE from the account which you wish to use to compile and run java programs. The location wasn't added to the path environment variable, so if you try to run the programs from a command prompt, you will see the following, unless you specify the full path name where the executable files are located.

C:\Users\Jim>java
'java' is not recognized as an internal or external command,
operable program or batch file.

C:\Users\Jim>javac
'javac' is not recognized as an internal or external command,
operable program or batch file.

C:\Users\Jim>

I didn't want to have to copy and paste the full path on the command line or type it in every time I wanted to use the two executables from the command line. To avoid that problem you can add the directory path to the path environment variable through a set path= command or create another environment variable, e.g., JAVA_HOME that points to the directory where the two files are located, though both methods apply only to a particular command line instance. I.e., if you close a command prompt window where you've set one of the variables to include the location where Eclipse installed java.exe and javac.exe then open another command prompt window, you will have to set the environment variable again in the new instance. An alternative way to make a permanent path change from a command prompt interface is to use the Windows setx command, though I would not recommend it, since if your path variable already has a path that is more than 1,024 characters long, setx can truncate the path to 1,024 characters, so that you not only don't get the additional directory added to the path, but you may lose some of the path setting you had prior to issuing the command. If you want to make a permanent change, see responses to the "Overcoming the 1024 character limit with setx" posting at the superuser.com site.
