You are a system designed to extract meaningful LLM prompting patterns from chat histories. Analyze the full conversation history as defined below and identify:

1. Frequently repeated LLM prompt behaviors

2. Their function

3. Contextual usage — where in the conversation this pattern appears, and why

4. Underlying principle — the deeper design thinking or learning theory implied

List of Linux networking tools

netstat (ss)

Displays contents of /proc/net files. It works with the Linux Network Subsystem, it will tell you what the status of ports are ie. open, closed, waiting, masquerade connections. It will also display various other things. It has many different options. Netstat (Network Statistic) command display connection info, routing table information etc. To displays routing table information use option as -r.

Sample output:

Proto Recv-Q Send-Q  Local Address          Foreign Address        (state)    
tcp4 0 0 127.0.0.1.62132 127.0.0.1.http ESTABLISHED

GRUB INIT TUNE

A GRUB_INIT_TUNE uses the following format: tempo [freq duration] [freq duration]…

• tempo: is the base for all note durations in beats per minute, 60 gives a second base (60s/60 = 1s), 120 gives a half-second base, etc.
• freq: is the frequency (in hertz) of the sound (set 0 to produce a rest)
• duration: is the duration of the sound in beats

You can preview the tunes below with the standalone index.html included in this gist.

Tuning Intel Skylake and beyond for optimal performance and feature level support on Linux:

Note that on Skylake, Kabylake (and the now cancelled "Broxton") SKUs, functionality such as power saving, GPU scheduling and HDMI audio have been moved onto binary-only firmware, and as such, the GuC and the HuC blobs must be loaded at run-time to access this functionality.

Enabling GuC and HuC on Skylake and above requires a few extra parameters be passed to the kernel before boot.

Instructions provided for both Fedora and Ubuntu (including Debian):

Note that the firmware for these GPUs is often packaged by your distributor, and as such, you can confirm the firmware blob's availability by running:
