readahead-list allows users to load files into the page cache before they are needed, to accelerate program loading. It improves on the existing readahead by taking the name of a file with the items to load, instead of requiring the arguments being passed as parameters. Additionally, it contains a tool (filelist-order) to optimize the order of the file list in several possible ways.
ramlog acts as a system daemon that maintains log files in memory instead of hard disk while the system is running. On startup, it creates a ramdisk, copies files from /var/log into the ramdisk, and mounts the ramdisk as /var/log. All logs after that will be updated on the ramdisk. When shutting down or restarting the service, it saves log files back to hard disk. This service drastically reduces the frequency of hard disk usage, which can be useful when the system runs on battery or uses flash memory instead of a hard disk.
Netplug is a Linux daemon that manages network interfaces in response to network cables being plugged in and out. If you're familiar with Windows XP, which just does the Right Thing when you plug an ethernet cable into a laptop, netplug will need no further explanation. Basically, netplug brings up an interface and runs a DHCP client when a cable is plugged into that interface, and it brings the interface down when the cable is unplugged. On a typical Linux system or laptop, you have to run a command (such as "/sbin/ifup") manually to handle these events, but netplug automates this for you.
xml-HTB is a tool for automatic generation of bash scripts that sets up HTB on Linux. It uses XML configuration files. It's easy to use, and features multiple depths of classes, configurable leaf, u32 and fw filters, and the ability to configure both the input and output interfaces at the same time.
