If you need to determine if a drive in a Microsoft Windows system or connected to it via USB is BitLocker encrypted, you can use the manage-bde utility. To use the program, open a command prompt window with administrator privileges and then issue the command manage-bde -status to see the status of all drives. To see just the status of one drive, e.g., C:, you could use manage-bde -status C:.

C:\Windows\System32>manage-bde -status c:

You can run the Big Fish Games Game Manager on an Ubuntu Linux system under Steam. You can install Steam as a Snap package from the Ubuntu App Center.

Steps:

1. Download the Big Fish Games App (Game Manager) for PC
2. In Steam on the Ubuntu system, click on Add a Game, which is at the lower, left-hand corner of the Steam window, then select Add a Non-Steam Game, then browse to where you downloaded the .exe installer for the game manager, click on it, and then click on Add Selected Programs.
3. You should then see the Big Fish Game Manager in the "Uncategorized" list of games at the left side of the Steam window, e.g., you may see bfginstaller32_s1_l1.exe listed. Right-click on it and then select Properties, then Compatibility, and then, from the drop-down list that becomes available, select Proton Experimental or the latest stable version — I selected Proton Experimental.
4. You can then close the Compatibility window by clicking on the "X" at the upper, right-hand corner.
5. Then with the Big Fish Game Manager selected in the Uncategorized list, click on the Play button to launch the Big Fish Game Manager Setup and agree to the License Agreement when you see it appear.

When I started the install process, the installation appeared to hang at "Execute: C:\Program Files (x86)\bfglient\epoch.exe". When I clicked on the title bar for the window, I saw "About Wine", so it appeared to be using Wine, which I had previously installed on the Ubuntu system. But I waited and eventually the installation succeeded, though I think it took over 15 minutes. I closed the window and then went back to the Steam window, I saw bfginstaller32_s1_l1.exe was still there. This time when I clicked on it, the Big Fish window where I could sign in to Big Fish Games opened fairly quickly.

Note: if the window goes blank or displays just a white background, minimize it by clicking on the "-" in the upper, right-hand corner of the Big Fish window and then switch to it again, which you can do with Alt+Tab — continue to press the Tab key while continuing to hold down the Alt key to cycle between open open windows until you get to the Big Fish window.

Initially, you will see "No games to play," but if you have already purchased games that you've played on another system, you can click on Purchase History and install them on the Linux system. When I installed the Big Fish Games Manager under Steam, I had my wife check one of her games, Aquascapes, and that ran fine. I then closed the Big Fish window and the Steam window and reopened it. Note: if you want to change the name that appears for Big Fish Games in the Uncategorized list, you can right-click on the entry, e.g., bfginstaller32_s1_l1.exe, and choose Properties and then change the "Shortcut" value to something you prefer, such as "Big Fish Games". When I reopened Steam and started Big Fish Games, I saw the Aquascapes game under "My Games".

If you need to determine the amount of memory in a system that is running the Ubuntu Linux operating system (OS), you can open a Terminal window from the App Center and then use the free command. If you use the command without any options, you will see the amount of memory displayed in bytes. To display the value in a more human-friendly format, you can add the argument -h or --human, e.g., to see the value in gigabytes.

alice@firefly:~$ free -h
               total        used        free      shared  buff/cache   available
Mem:            14Gi       2.4Gi        10Gi       426Mi       2.3Gi        12Gi
Swap:          4.0Gi          0B       4.0Gi
alice@firefly:~$

Other options for the command are shown below:

jim@Serenity:~$ free --help

Usage:
 free [options]

Options:
 -b, --bytes         show output in bytes
     --kilo          show output in kilobytes
     --mega          show output in megabytes
     --giga          show output in gigabytes
     --tera          show output in terabytes
     --peta          show output in petabytes
 -k, --kibi          show output in kibibytes
 -m, --mebi          show output in mebibytes
 -g, --gibi          show output in gibibytes
     --tebi          show output in tebibytes
     --pebi          show output in pebibytes
 -h, --human         show human-readable output
     --si            use powers of 1000 not 1024
 -l, --lohi          show detailed low and high memory statistics
 -L, --line          show output on a single line
 -t, --total         show total for RAM + swap
 -v, --committed     show committed memory and commit limit
 -s N, --seconds N   repeat printing every N seconds
 -c N, --count N     repeat printing N times, then exit
 -w, --wide          wide output

     --help     display this help and exit
 -V, --version  output version information and exit

For more details see free(1).
jim@Serenity:~$ 

Note:The free command in Linux shows the total amount of installed physical memory in the total column, but this value is less than the actual hardware random-access memory (RAM) installed because the Linux kernel reserves a portion of memory for itself and for hardware devices (like video card buffers) at boot time. The total shown is the usable RAM available to the OS, not the absolute hardware total.

On a Ubuntu Linux system, you can determine which users are allowed to use the sudo command by looking at the contents of the /etc/group file. If you grep for sudo you will see which accounts on the system can use the command.

jack@firefly:~$ grep sudo /etc/group
sudo:x:27:jack,jill@ad.example.com
jack@firefly:~$ 

The above output shows that the local jack account and a Windows domain account, jill@ad.example.com, can use the command. You can see what groups a particular user belongs to with the command groups username, where username is the user's account name.

jack@firefly:~$ groups jill@ad.example.com
jill@ad.example.com : domain users@ad.example.com ra_allowmediaaccess@ad.example
.com ra_allowcomputeraccess@ad.example.com ra_allowaddinaccess@ad.example.com ra
_allowshareaccess@ad.example.com ra_allowremoteaccess@ad.example.com wssusers@ad
.example.com ra_allowvpnaccess@ad.example.com ra_allowhomepagelinks@ad.example.c
om
jack@firefly:~$ groups jack
jack : jack adm cdrom sudo dip plugdev users lpadmin
jack@firefly:~$

You can also determine if a user has sudo privilege using groups username | grep -c sudo. If the result is 0, then the user does not have that privilege. If the result is 1, inciding that the grep command found username one in the output of the groups command, then the user has that privilege.

jack@firefly:~$ groups jill@ad.example.com | grep -c sudo
1
jack@firefly:~$

You can grant a user that privilege by issuing the command sudo usermod -aG sudo username from an account that already has the capability to run the sudo command.

jack@firefly:~$ sudo usermod -aG sudo mary
[sudo: authenticate] Password:
jack@firefly:~$

You can remove a user's account from the list of those allowed to run the command using the gpasswd command, which is part of the sysutils package by issuing the command sudo gpasswd -d username sudo.

jack@firefly:~$ sudo gpasswd -d mary sudo
Removing user mary from group sudo
jack@firefly:~$ groups mary | grep -c sudo
0
jack@firefly:~$

Python Code:

from datetime import date

# Get today's date as a date object
today = date.today()

# Format the date into a string variable in YYMMDD format
# %y gives the two-digit year, %m gives the zero-padded month, and %d gives the # zero-padded day formatted_date_string = today.strftime("%y%m%d")

# Print the result (optional, for verification)
print(f"Today's date in YYMMDD format: {formatted_date_string}")

Steps:

• from datetime import date: This line imports the date class from the built-in datetime module, which is necessary to work with dates in Python.
• today = date.today(): This uses the today() method to get the current local date as a date object.
• today.strftime("%y%m%d"): The strftime() method is then applied to the today object to format it into a string. The format string uses specific directives:
  • %y: Represents the year without the century (e.g., 26 for 2026).
  • %m: Represents the month as a zero-padded decimal number (e.g., 02 for February).
  • %d: Represents the day of the month as a zero-padded decimal number (e.g., 15 for the 15th).

The resulting string, stored in formatted_date_string, will look like 260215 (for February 15, 2026)

OpenSSH Server for Windows 10 requires at least Windows 10 (build 1809). You can determine the build number for Windows 10 by typing winver in the Windows "Type here to search" field at the bottom of the screen or at a PowerShell prompt. Or you can use the systeminfo utility and pipe it's output into the findstr command, filtering on the line that has "OS" at the beginning of the line and also "Version" in the line.

PS C:\> systeminfo | findstr -B "OS" | findstr "Version"
OS Version:                10.0.19045 N/A Build 19045
PS C:\>

The SSH Client software may already be installed. You can determine if it is already installed by opening a PowerShell prompt and typing ssh. If it is installed, as it was on the Windows 10 Professional Version 22H2 (OS Build 19045.6466) system on which I wanted to set up the OpenSSH Server software, you will see a response like the following one:

PS C:\> ssh
