Cleaning a computer requires two aspects: appearance and system. 1. Appearance cleaning: Use a soft brush, compressed air and microfiber cloth to clean the keyboard, body and screen after power outage every 1-2 months to avoid liquid penetration; 2. System cleaning: Windows can delete temporary files through settings, use disk cleaning tools and uninstall useless software. Mac can use terminal commands and storage management functions to optimize storage and clear wastebasket; 3. Startup item and process management: Windows disables the self-start program in the Task Manager and ends the high-occupancy process, and Mac adjusts the startup item and exits the abnormal program through the login item settings and activity monitor. Regular maintenance can keep the computer running smoothly.
It is actually not difficult to clean the computer. The key is to distinguish whether to clean the appearance or the inside of the system. Many people mistakenly think that "cleaning" means deleting a few files, but in fact, it includes hardware dust removal, software optimization and other aspects. Let’s talk about how to do it in detail.

Clean the computer case and screen
After using the computer for a long time, dust will accumulate on the keyboard seams, body surface and screen, affecting the user experience and even cooling. It is recommended to do external cleaning every 1-2 months.
- Tool preparation : soft brush, compressed air tank, microfiber cloth, a small amount of detergent (such as special screen wipes).
- Operation sequence :
- Remove the power first and then wipe it to avoid electric shock or damage to the equipment.
- The keyboard gap can be swiped with a soft brush or blow out dust with compressed air.
- Do not use alcohol or detergents containing corrosive ingredients on the screen to avoid damaging the coating.
- Note : Do not let liquid penetrate into the interface or press the button, otherwise it may be short-circuited.
Clean up system junk files and caches
Windows or macOS will accumulate a large amount of useless data such as temporary files, logs, caches, etc. over time. This part of the cleaning can free up space and sometimes increase the running speed.

- Windows can do this :
- Open "Settings>System>Storage", click "Temporary File", check the content you want to delete and clean it up.
- Use the Disk Cleanup Tool (Search for "Disk Cleanup"), select the C disk for scanning and cleaning.
- Regularly uninstall software that is no longer used to avoid slowing down the startup speed of the background self-start.
- Mac users can try :
- "Go to > Applications > Utilities > Terminal", enter
sudo rm -rf /var/log/*.log
to delete some logs (careful). - Use the included "About Native > Storage > Management", select "Optimize Storage" or manually clean large files.
- Clearing the "wastebasket" and "mail attachment cache" can also make a lot of space.
- "Go to > Applications > Utilities > Terminal", enter
Check and clean up startup items and background processes
Slow boot? Maybe there are too many startup items. System operation is stuttering? It may also be that the background program occupies resources.
- On Windows :
- Press Ctrl Shift Esc to open the Task Manager → "Start" tab to disable unnecessary boot program.
- Check the CPU and memory usage in the "Performance" tab, and end the process of occupancy exceptions.
- On Mac :
- Open "System Settings > Users and Groups > Login Items" and delete the unwanted startup items.
- Open the "Activity Monitor" to see which programs are secretly eating resources and force exit if necessary.
Basically that's it. Cleaning the computer is not a one-time thing, and regular maintenance is the most effective. Some places seem small, such as clearing a cache or closing a startup item, but not doing it for a long time, problems will gradually increase.

In Java development, code refactoring is a very important link. It can help us improve code quality, reduce code redundancy, and improve maintainability and performance. This article will share some experiences and suggestions on code refactoring, hoping to be helpful to Java developers. Determine the goals of refactoring Before refactoring code, you first need to clarify what the goals of refactoring are. Is it to improve code readability? Or is it to improve performance? Or is it to fix bugs? Clear goals can help us refactor in a more targeted manner instead of blindly making changes.

The update and maintenance strategy of Go function libraries is crucial to system stability. The following best practices provide guidance: Update strategy: Automatic updates: Use GoModules or other tools to automatically update dependencies. Manual updates: Check regularly and update to new versions manually. Maintenance strategy: Version locking: Use the -u flag when updating dependency versions to avoid accidental updates. Periodic auditing: Use golist-u to check for updates and audit dependencies. Library forks: For critical libraries, consider creating your own fork to gain more control. By using GoModules, continuous integration testing, and dependency management, libraries can be efficiently kept updated and maintained.
