A few comparisons with what we discovered about Michael Ball yesterday

In the early 2000's, digital forensics was a new sport, and I had a few forensics certs.

After what we just learned about @unix_guru, I thought I might talk about two cases I worked on that will give an idea what to expect going forward. They both had entirely different outcomes, and in both cases on behalf of the defense.

CASE#1: The officers received child pornography in an IRC (chat system) sting operation. This led to an arrest, and the officers found what they described as "the worst child pornography we've seen" and "toddler porn." Adding to the urgency, the suspect's wife was pregnant and expecting a daughter, and the charges were a clear threat to the family unit.

I want to partner with @elonmusk growing #cannabis in near-Earth orbit.

You place an order, look outside and see a streak across the sky. It lands at a
local "last mile" area, and then gets local autonomous delivery to the destination.

Bash users already know you can !$ to run a different command with previous args.

-> ls text.txt ; less !$ # becomes *less text.txt*

Today I discovered $:0

-> ls text.txt ; $:0 less # becomes *less text.txt*

Mind. Blown!

  "ay cubed plus bee cubed plus cee cubed equals 3 period"

I was thinking about those so-called ghost scanners and came up with an idea for sending secret messages.

The way the scanners work is they monitor a radio frequency that is saturated with white noise, and then 
feed the audio static to a voice recognizer. Sometimes it picks up "words" in the static, and displays a
text transcription of it. Real live ghosts... spooky!

So now it makes me wonder if anyone hacking their Siri/Alexa/Whomever has trimmed samples of these ghost
words to send messages using static that was fuzzed from the airwaves...

Sure, it isn't practical in so many ways, but it would still be a fun hack. At least as fun as the video

From: https://clisp.sourceforge.io/impnotes/quickstart.html#quickstart-unix (very end of page):

32.6.4. Associating extensions with CLISP via kernel
Platform Dependent: Linux platforms only.
You have to build your kernel with CONFIG_BINFMT_MISC=y and CONFIG_PROC_FS=y. Then you will have a /proc/sys/fs/binfmt_misc/ directory and you will be able to do (as root; you might want to put these lines into /etc/rc.d/rc.local):

# echo ":CLISP:E::fas::/usr/local/bin/clisp:" >> /proc/sys/fs/binfmt_misc/register
# echo ":CLISP:E::lisp::/usr/local/bin/clisp:" >> /proc/sys/fs/binfmt_misc/register
Then you can do the following:

function retry(isDone, next) {
    var current_trial = 0, max_retry = 50, interval = 10, is_timeout = false;
    var id = window.setInterval(
        function() {
            if (isDone()) {
                window.clearInterval(id);
                next(is_timeout);
            }
            if (current_trial++ > max_retry) {
                window.clearInterval(id);
