Minification can help your website load several times faster
In production, it is recommended to minify any JavaScript code that is included with your application. Minification can help your website load several times faster, especially as the size of your JavaScript source code grows.
Here’s one way to set it up:
npm init -y in your project folder (don’t skip this step!)npm install terserNow, to minify a file called like_button.js, run in the terminal:
npx terser -c -m -o like_button.min.js -- like_button.js
This will produce a file called like_button.min.js with the minified code in the same directory. If you’re typing this often, you can create an npm script to give this command a name.

Yes you can delete everything inside of /var/log/journal/* but do not delete the directory itself. You can also query journalctl to find out how much disk space it’s consuming:
$ journalctl --disk-usage
Journals take up 3.8G on disk.
You can control the size of this directory using this parameter in your /etc/systemd/journald.conf:
SystemMaxUse=50M
You can force a log rotation:
$ sudo systemctl kill --kill-who=main --signal=SIGUSR2 systemd-journald.service
NOTE: You might need to restart the logging service to force a log rotation, if the above signaling method does not do it. You can restart the service like so:
$ sudo systemctl restart systemd-journald.service
These files too under /var/cache/abrt-di/* can be deleted as well. The size of the log files here is controlled under:
$ grep -i size /etc/abrt/abrt.conf
# Max size for crash storage [MiB] or 0 for unlimited
MaxCrashReportsSize = 1000
You can control the max size of /var/cache/abrt-di by changing the following in file, /etc/abrt/plugins/CCpp.conf:
DebugInfoCacheMB = 2000
NOTE: If not defined DebugInfoCacheMB defaults to 4000 (4GB).

Many modern file systems employ a journal including NTFS, Ext3/4, XFS, HFS+, and others. The journal helps with two things, avoiding file system corruption and speeding up recovery after a failure such as a power loss or system crash. There are two major components to a file system, the data and the metadata. The data is the contents of a file, image, video, documents, and ultimately it is what gives the file system it’s value. The metadata is what describes the structure of the filesystem including how files are named, stored in directories, access permissions, file modification times, and recording areas of the disk that are in use or are free to be allocated to other files as they grow or are created. If the metadata becomes corrupted because of a system crash, it could lead to further data loss/corruption. For example, part of the disk might be selected for allocation to a file, but if it’s not recorded correctly before a crash, it might be added to the file’s list of data blocks, but still in the list of free data blocks and allocated to a second file later on. Now, there are two files that are sharing the same data blocks/content.
The journal is a place on the disk reserved for recording changes to the file system. The exact details of what is being changed it written first to the journal located in a single location on disk, then, after the journal is updated, the changes are applied to the appropriate locations on the disk which might require several writes. One the updates are done, the journal entry is marked as complete. After a crash, the system only need to examine the journal for incomplete entries and complete them to fix the file system. This speeds recovery and ensures a change is made entirely or not at all. If a block is allocated to a growing file, it will be added to the file’s block list and also marked as in use.
Also, on file systems that support journalling, most often it’s only metadata journalling to preserve the structure, but not the data itself. Full data journalling is normally quite expensive and slow, but less crucial than metadata. It’s possible to enable for data as well if needed.
Also, to complete this, there are some file systems that don’t currently offer journalling including FAT32, exFAT, Ext2, and UDF. If there’s a crash during an update, a full scan of the filesystem needs to be done to track down any errors or corruption.
