From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Mosh: Like ssh, but better (e.g. local echo and persistent sessions across sleeps / network changes) (mosh.org)

TCP was never designed with wifi in mind. TCP retransmission was only ever meant to handle drops due to congestion, not lossy links.

Tmux is a wonderful complement to mosh. Together you get persistence even when your local client loses power (speaking from experience)

I still remember the professor in my networks class explaining how TCP worked, and then saying more or less:

Why doesn't it send a detailed mapping of which sections of the stream have been received and which haven't, allowing retransmission of only the dropped packets instead of what it does which is just backing up and blasting a whole new window's worth every time a single packet is dropped? Well, I don't know. It'd be a little more complex but the improvement in functionality would be so obviously worth it that it should. Don't know what to tell you. Anyway, this is how it works...

TCP Selective Ack is very much a thing, but it does take extra memory so lots of TCP stacks exclude it or disable it by default.
