you can start. At the same time, pay attention to the place where you place the ISO file. If your home directory is encrypted or cannot be accessed, you may prefer to put these files into startup partitions like in the example. However, make sure that there is sufficient space for the start partition. Finally, do not forget to save the 40_custom file and use the following command to update grub: # Sudo update-grub So that you can see the changes at the next startup. What to do next? Want mor

crashes. These operations should not be performed on the latest Linux system. Note: I should not. I didn't say no. Correctly set user permissions. Linux can prevent these destructive behaviors. Generally, users are limited to allocating available machine memory. But if you run this line of command (or its variant Bash fork bomb variant [5]) as the root user, you can still abuse the server until the system restarts.

ADB = ∠ ACB.3. Take a little K on the AC so that ∠ ABK = ∠ CBD; Because ∠ ABK + ∠ CBK = ∠ ABC = ∠ CBD + ∠ ABD, ∠ CBK = ∠ ABD.4. Therefore, △abk is similar to △dbc. Similarly, △abd is similar to △kbc.5. Therefore, AK/AB = CD/BD and CK/BC = DA/BD;6. Therefore, AK * BD = AB * CD and CK * BD = BC * DA;7. The two formula is added to get (AK + CK) * BD = AB * CD + BC * DA;8. But AK + CK = AC, so AC * BD = AB * CD + BC * DA. Pass. Geometric proof of Inverse TheoremUsing the ry method, we can also pr
