I was shown this thing called SSI. It’s the sneakiest of tricks for primitively boosting any SSG. It’s supported in the web servers nginx, apache, lighttpd, and others.

server {
  ssi on;
  ssi_last_modified on;
}

There’s a quick way to test the offline behaviour of programs on Linux.

unshare -c -n bash

$ ip addr
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

List network namespaces with lsns.

$ lsns -t net
NS  TYPE NPROCS PID   USER  NETNSID    COMMAND
999 net  2      111   user  3          systemd
888 net  1      222   user  unassigned └─bash

I came across a peculiar site. It’s called https://no-color.org (terminals). Xterm and ansifilter work well for programs that are unable to contextually disable colors.

ls -la | ansifilter   # Remove colors from output
xterm -cm             # Set color mode to false
export NO_COLOR=true  # For programs that follow

I used to wonder why some preferred no syntax/color highlighting. It turns out that output can/will be hidden (e.g black on black, white on white) and color contrasts/distinctions are the ultimate talk past.

The interest in TUIs online is high. In the real world you tend to be constrained and blindfolded by the tools available/allowed. Filtering is peculiar though.

See how the terminal/editor splits? Filtering makes them kiss? Commands that input|output (pipe) work best (compilers, transpilers and code generators). The meta is the limit.
