Make sure you have antifreeze, rather than pure water, in the cooling system. Pure water will crack the engine block and/or radiator when it freezes.

If you have a system with long-running leaky browser instances, Alt-SysRq-F is a lifesaver. It calls oom_kill, sacrificing one process to save the rest.

Technically, XZ is just a container that allows for different compression methods inside, much like the Matroska MKV video container. In practice, XZ is modified LZMA.

There is no perfect algorithm for every situation, so I’ll attempt to summarize.

• Gzip/zlib is best when speed and support are the primary concerns
• Bzip2 was largely phased out and replaced by XZ (LZMA) a decade ago
• XZ (LZMA) will likely give you the best compression, with high CPU and RAM usage
• Zstd is… really good, and the numerous compression levels offer great flexibility

The chart below, which was sourced from this blog post, offers a nice visual comparison.

You are looking for a “dual WAN router.” The TP-Link ER605 v2 (don’t get v1) might be a good option for you. B&H Photo is a better seller than Amazon to ensure you get the v2. It is wired-only, so you’ll need something else to cover your wireless needs. Your existing router may work fine as an access point.
