If you’ve ever wondered, there are actually scans like this on the net:

curl --resolve a:80:127.0.0.1 http://a/b/c
curl --resolve *:80:[::1]     http://-

These are the watering holes that newer crawlers tend to poke around nowadays:

I think someone asked. But is it possible to classically convert a PDF into JSON? And the answer is yes, yes you can. The feats of programming know no end (it’s out of my explanatory scope, sorry).

qpdf --json-output my.pdf my.json

I’m finally realizing that in the stack link of this post, there’s actually an entry about “grepping” the device. Everything’s a file or something. It feels comical.

There’s truly nothing more liberating than deleting all of your work by mistake (or having it deleted). That’s why it never hurts to have multiple distribution (and backup) strategies. A newer way is invented every day:

gcc -o delete-this-file.c

Why dabble with Firefox? Everything is customizable. How long will this be so? Who knows. E.g, I have custom stylesheets that hide comments everywhere (Firefox/Chrome) among other things. “Experts” only?

about:debugging#/runtime/this-firefox

chrome://browser/content/browser.xhtml

toolkit.legacyUserProfileCustomizations.stylesheets true

How hard is it to run Linux? It depends on your luck and persistence. I received a junked Lenovo 11e Chromebook recently and it would always freeze at 99% during any distribution install (classic). Enabling a kernel parameter fixed it. How did I know this? Don’t even ask.

#define SDHCI_QUIRK_BROKEN_CQE (1<<17)
(1<<17) = 0x20000

sdhci.debug_quirks=0x20000

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

$ 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.
