To grant read-write access to an external SSD/HDD on Ubuntu 22.04, you can follow these steps:

Connect the external SSD/HDD to your Ubuntu machine.

Open a terminal and enter the following command to identify the device name:

sudo fdisk -l

The output should list all the connected devices, including the external SSD/HDD. Identify the device name of the external SSD/HDD from the list. It should be something like /dev/sdX (where X is a letter).

Create a mount point for the external SSD/HDD by entering the following command:

sudo mkdir /media/<mount_point>

Replace with a name you prefer. This will be the folder where the external SSD/HDD will be mounted.

Grant ownership of the mount point to the current user by entering the following command:

sudo chown -R $USER:$USER /media/<mount_point>

Add an entry for the external SSD/HDD in the /etc/fstab file to ensure that it is mounted automatically when the system starts up. Open the /etc/fstab file with the following command:

sudo nano /etc/fstab

Add the following line at the end of the file:

/dev/sdX /media/<mount_point> ext4 defaults 0 0

Replace /dev/sdX with the device name of the external SSD/HDD that you identified in step 2, and with the name of the mount point that you created in step 3.

Save and close the /etc/fstab file by pressing Ctrl+X, then Y, and then Enter.

Mount the external SSD/HDD by entering the following command:

sudo mount -a

This should mount the external SSD/HDD to the mount point that you created in step 3.

Now, you should have read-write access to the external SSD/HDD on your Ubuntu 22.04 machine.

To set a D3cold state flag for NVMe with a udev rule in Ubuntu 22.04, you can follow the steps below:

Identify the NVMe device you want to apply the D3cold state flag to by running the following command in the terminal:

ls /sys/class/nvme/

This will list all the NVMe devices present in the system.

Once you have identified the NVMe device, create a new udev rule to apply the D3cold state flag. You can do this by creating a new file in the /etc/udev/rules.d/ directory with a .rules extension. For example, you can create a file named nvme-d3cold.rules by running the following command:

sudo nano /etc/udev/rules.d/nvme-d3cold.rules

In the new file, add the following rule:

# Set D3cold state flag for NVMe device
SUBSYSTEM=="nvme", KERNEL=="nvmeX", ATTR{power/control}="auto"

Replace nvmeX with the name of the NVMe device you identified in step 1.

The ATTR{power/control}=“auto” attribute sets the power management policy to “auto”, which enables the kernel to select the optimal power management policy for the device.

Save and close the file.

Reload the udev rules by running the following command in the terminal:

sudo udevadm control --reload-rules

This will apply the new udev rule and set the D3cold state flag for the specified NVMe device.

Note: The D3cold state flag may not be supported by all NVMe devices. Make sure to check the specifications of your NVMe device before applying the udev rule.

Explanation regarding D3cold

D3 Cold is a power state in the NVMe (Non-Volatile Memory Express) specification that is designed to reduce the power consumption of NVMe devices when they are not in use. When an NVMe device enters the D3 Cold state, it is put into a deep sleep mode where its power consumption is reduced to near-zero.

The D3 Cold state is a very deep sleep state that requires some time for the device to wake up and become operational again. During this time, the device will consume more power as it initializes and becomes ready for use. However, the power savings from being in the D3 Cold state for extended periods can outweigh the time and power required to wake up from this state.

The D3 Cold state can be enabled by setting the power/control attribute to “auto” in the udev rule for the NVMe device, as described in my previous answer. When the kernel decides that the device is idle, it can transition it into the D3 Cold state to save power.

HDCP (High-bandwidth Digital Content Protection) is a copy protection technology that is used to prevent unauthorized copying of digital video and audio content. The Intel Management Engine (ME) is a hardware-based security feature that is built into some Intel processors.

Enabling the Intel ME does not directly affect HDCP support on Linux. However, there are a few things to keep in mind when using HDCP on Linux:

HDCP support on Linux can be limited, depending on the graphics card and driver you are using. Some graphics cards may not support HDCP at all, and some drivers may not have full HDCP support.

To enable HDCP on Linux, you will need to install the necessary software packages and configure your system appropriately. The specific steps required will depend on your Linux distribution and graphics hardware.

In order to use HDCP on Linux, you will also need compatible hardware and software for both the source and destination devices (e.g. the media player and the display).

Overall, enabling the Intel ME should not have a direct impact on HDCP support on Linux. However, HDCP support on Linux can be limited, and you may need to take additional steps to enable HDCP on your system.

The command “OOBE\BYPASSNRO” is a command that can be used in Windows 11 to skip the “New Network Connection Detected” prompt that can sometimes appear during the Out of Box Experience (OOBE) process.

During the OOBE process, Windows may detect a new network connection and prompt the user to confirm that they want to connect to it. This can sometimes be an issue if the computer is not connected to a network or if the user wants to skip this step. To use the “OOBE\BYPASSNRO” command, you can press the Shift + F10 keys during the OOBE process to open a Command Prompt window. Then, type the command “OOBE\BYPASSNRO” and press Enter to skip the “New Network Connection Detected” prompt.

There might be the possibility that macro hard will patch this feature, not bug out. In the future.

In Linux, the term “base files” is commonly used to refer to the essential files and directories that make up the core operating system. These files are typically installed as part of the initial Linux installation and provide the foundation for running the system and its various applications. Some of the key Linux base files include:

The Linux kernel – this is the core component of the operating system that interacts with the hardware and manages system resources. The root file system – this is the top-level directory in the Linux file system hierarchy, which contains important system files and directories, such as

/bin, /etc, /sbin, /dev, and /usr.

Configuration files – these files contain settings and parameters that define how various system and application components work together. System libraries – these are collections of precompiled code that are used by various applications and utilities to perform common functions. Device drivers – these are software components that allow the operating system to communicate with hardware devices, such as printers, network adapters, and storage devices.

Overall, the Linux base files provide a solid foundation for running the operating system and its applications, and are critical to the stability and reliability of the system.

VFAT (Virtual File Allocation Table) is a file system that was introduced by Microsoft as an extension to the FAT (File Allocation Table) file system. VFAT was first introduced in Windows 95 and is still used in some versions of Windows today.

The main difference between VFAT and FAT32 is the way they handle long filenames. VFAT allows for long filenames (up to 255 characters) to be used, while FAT32 only allows for short filenames (up to 8 characters) with a 3 character extension.

VFAT uses a technique called “name mangling” to convert long filenames into a format that can be stored on a FAT file system. This involves using a combination of short names and additional metadata to represent the full long filename.

Another difference between VFAT and FAT32 is the way they handle file fragmentation. VFAT uses a technique called “cluster chaining” to allocate space for fragmented files, while FAT32 uses a technique called “extents” to keep track of file fragments.

Overall, VFAT is an extension to the FAT file system that provides support for long filenames, while still maintaining backwards compatibility with older operating systems that use the FAT file system. FAT32, on the other hand, is a newer version of the FAT file system that was designed to provide better support for larger hard drives and larger files, but it does not provide support for long filenames like VFAT does.

hciconfig hci0 | grep "HCI Version"

This will display only the line that contains the “HCI Version” field for the device with interface name “hci0”. If you want to display the “HCI Revision” field instead, simply replace “HCI Version” with “HCI Revision” in the command.

A dead man's switch is a mechanism that is designed to automatically take action if the operator of a device becomes incapacitated or unable to maintain control. It is commonly used in situations where an operator's failure to maintain control could result in harm or damage, such as on trains or other heavy machinery.

The way a dead man's switch works is by requiring the operator to actively maintain contact with a switch or button. If the operator releases the switch or button, the device will automatically stop or take some other action, such as applying the brakes or shutting off the engine. This ensures that if the operator becomes incapacitated or loses control of the device, it will automatically stop and prevent harm.

Creating a dead man's switch can vary depending on the device or system you want to apply it to. However, the basic idea is to connect the switch to a control mechanism that will take the necessary action if the switch is released.

For example, if you wanted to create a dead man's switch for a power tool, you could connect a switch to the tool's power source, such that the tool only runs while the switch is held down. If the operator releases the switch, the power to the tool is cut off. It's important to note that designing and installing a dead man's switch requires careful consideration of the specific device or system in question. It is recommended that you consult with a professional or expert in the field before attempting to create a dead man's switch. A software dead man's switch can be created using programming techniques to automatically trigger an action if the software system or application fails to receive a signal or response from the operator within a specified timeframe. Here are some general steps to create a software dead man's switch:

Identify the trigger event: The first step is to identify the event that will trigger the dead man's switch. For example, the trigger event could be the lack of response from the operator for a specified period of time.

Set a timer: Once the trigger event is identified, a timer needs to be set to monitor the elapsed time between the trigger event and the response from the operator.

Define the action: You need to define what action should be taken when the timer expires. This could be as simple as logging out the user or shutting down the software, depending on the context of the application.

Implement the code: You will need to implement the code that monitors the timer and triggers the defined action when the timer expires. This code can be integrated into the main application or run as a separate process in the background.

Test and optimize: Finally, you will need to test the software dead man's switch to ensure it works as intended. You may also need to optimize the timing parameters based on user behavior and the requirements of the application.

It's worth noting that the design and implementation of a software dead man's switch will depend on the specific application and the context in which it will be used. Therefore, it's important to consult with a professional software developer or engineer to ensure that the software dead man's switch is reliable and effective. For example, if you have some information that might be very interesting to certain people and you are an activist under constant threat from certain groups, you could create such a switch to inform people about why you might have been harmed.
