Mar 20, 2024 am 10:55 AM
In Ubuntu systems, the root user is usually disabled. To activate the root user, you can use the passwd command to set a password and then use the su- command to log in as root. The root user is a user with unrestricted system administrative rights.

How to mark minesweeper? -How to change the difficulty of Minesweeper?
Mar 18, 2024 pm 06:34 PM
How to mark minesweeper? First, we need to familiarize ourselves with the marking method in Minesweeper. Normally, there are two common marking methods in Minesweeper games: flag marking and question mark marking. The flag mark is used to indicate that there are mines in the block and is a deterministic mark; while the question mark mark indicates that there may be mines in the block, but it is not deterministic. These two marking methods play an important role in the game, helping players to infer which blocks may contain mines, so as to effectively proceed to the next step. Proficient use of these marking methods can improve the player's success rate in the minesweeper game and reduce the risk of stepping on mines. Therefore, when playing the minesweeper game, if the player has mastered the flag mark and question mark mark, when the player is not sure whether there is a mine in a certain square, he can use the question mark mark to mark it.

Improved security: By using sudo, you can avoid using the root account during routine operations. Using the root account for all operations may lead to unexpected system damage, as any mistaken or careless operation will have full permissions. and
