About

This plugin goes to great lengths to save and restore all the details

from your tmux environment. Here's what's been taken care of:

all sessions, windows, panes and their order

current working directory for each pane

exact pane layouts within windows (even when zoomed)

active and alternative session

active and alternative window for each session

windows with focus

active pane for each window

"grouped sessions" (useful feature when using tmux with multiple

monitors)

programs running within a pane! More details in the restoring

programs doc.

Optional:

restoring vim and neovim sessions

restoring pane contents

restoring a previously saved environment

Installing TPM (Tmux Plugin Manager) , Tmux Resurrect and Tmux

Continuum

In ~/.tmux/plugins/

git clone https://github.com/tmux-plugins/tpm.git

git clone https://github.com/tmux-plugins/tmux-resurrect.git

git clone https://github.com/tmux-plugins/tmux-continuum.git

In a tmux window

I first want to apologize for my crappy show notes.

That out of the way. Welcome to LinuxLUGCast episode 217 the

pre-show. Normally this gets tacked on to the end of the regular

podcast, but Ken put out a call for shows and we figured this was the

easiest way to get a show out. I was going to try to meet up with these

same people on Mumble and talk about something technical for HPR, but

let's be honest the conversation would probably still have turned into

TV and movies, and we were already together and recording. Plus

hopefully I can use this to convince other people to come and join the

Lugcast. We record every first and third Friday of the month using

mumble. Check out linuxlugcast.com for all the details.

Introduction

A time stamp is added for each item I mention. The time stamp given

does not include the intro added by HPR so you’ll need to add a few more

seconds to get to the the correct spot in the recording.

[1:20] - I mention that if you are struggling to think of a topic for

an HPR show then the HPR site contains a list of requested topics which

you can choose from. https://hackerpublicradio.org/requested_topics.php

[1:55] - Picture 01 show the “Wenger” rucksack (Backpack) I take to

work. It was purchased many years ago and is probably no longer

available.

First front zip section

[3:20] - I mention that I suffered for many years with Hay fever and

have had great success with Mixed Pollen 30C tablets which I bought on

Amazon. Unknown to me at the time these were Homeopathic with miniscule

concentration. Despite this they seems to have cured my Hay fever. Refer

to the links below.

bought from Amazon. Strangely they seem to constantly fall out of my

left ear but remain in my right ear.

[5:40] - Picture 02 shows the leather pouch pocket protector that I

used to carry coins. I no longer have a use for it as I no longer carry

change. Despite this for some reason I still continue to carry it back

and forward to work.

Marshals Service Computer System Hit by Ransomware Attack.

Author: Michael Kan. (2023,

Feb 28).

The agency uncovered the intrusion on Feb. 17 2023, when it

discovered “a ransomware and data exfiltration event affecting a

standalone USMS system.” That means the hackers stole information from

the computer while planting malicious code capable of encrypting the

data inside.

“The affected system contains law enforcement sensitive information,

including returns from legal process, administrative information, and

personally identifiable information pertaining to subjects of USMS

investigations, third parties, and certain USMS employees,” the agency

says.

Shuts Down 'Netwire' Malware That Posed as Legit Remote Admin Tool.

Author: Michael Kan. (2023,

Mar 10).

Worldwiredlabs.com has been around since at least 2012(Opens in a

new window), offering a software product called “Netwire,” which is

supposedly designed to help IT support staff manage computers remotely.

Before the site was seized, it was offering Netwire for $10 per month or

$60 per year. However, US investigators say the site was a front to sell

the software as a hacking tool to cybercriminals.

Authorities Seize Internet Domain Selling Malware Used to Illegally

Control and Steal Data from Victims’ Computers.

Author: U.S. Attorney's Office, Central District of

California. (2023, Mar 9).

A seizure warrant approved by a United States Magistrate Judge on

March 3 and executed on Tuesday led to the seizure of

www.worldwiredlabs.com, which offered the NetWire remote access trojan

(RAT), a sophisticated program capable of targeting and infecting every

major computer operating system. “A RAT is a type of malware that allows

for covert surveillance, allowing a ‘backdoor’ for administrative

control and unfettered and unauthorized remote access to a victim’s

computer, without the victim’s knowledge or permission,” according to

court documents filed in Los Angeles.

This game is pretty old, but I found that wen I started a game

recently to prepare for this episode that it was still as addictive as

ever. I won't claim it is essential for everyone to run out and get it,

but if you did happen to find a copy somewhere and play it, you might

find you enjoy it. In this episode I give a few hints about getting

started with this game.

Biking to Work

In this episode I record while I'm riding my bicycle to work, using my new audio adapter to plug my $2 microphone into my phone. To make the recording I used the Hi-Q mp3 recorder app on my Android device. In the end I didn't do anything in post-production to adjust the volume or compression of the audio. It turned out pretty well "as is."

Make a Vortex Cannon.

This is a device for firing a coherent torus-shaped vortex across a room. If it is made with a degree of care, it will extinguish the flame of a candle from some distance.

What you will need

An empty Pringles can. This is the cylindrical foil-lined cardboard tube which originally contained Pringles potato chips.

A party balloon.

Some strong parcel tape.

A hole punch capable of making a clean hole of about two centimetres (three quarters of an inch) in diameter.

A small drill.

What to do

Step 1:

Drill a small hole in the metal end-plate of the Pringles can. This hole needs to be large enough to accommodate the threaded portion of the hole punch.

The hole needs to be as close to the exact dead-centre of the plate as you can make it.

Use the hole punch to make as clean as possible a hole as accurately as possible.

Here in the UK it is possible to obtain a hole punch called a Q-Max punch from Maplin, the supplier of electronic and hobby parts.

I am sure they are available from other sources.

It is very important that this hole is:

As close to the centre of the end-plate as is humanly possible

Has edges which are clean and crisp. Hence the use of a hole punch.

It is these two factors more than any other that will effect the efficiency of the cannon.

Step 2:

Cut off the mouth-piece end of the balloon.

Stretch it over the open end of the Pringles can and pull it as tight over the end as you can.

When I say the open end I mean the end from which you removed the lid and chomped on the chips.

Use the parcel tape to wrap the balloon tightly around the circumference of the cylinder, anchoring it in position so that the open end of the can is now like a drum formed by the stretchy membrane of the balloon. Nice and tight.

The cannon is now ready to fire.

Firing the cannon

Pinch the centre of the balloon membrane and pull it back as far as you can. This might be easier if you push some kind of (blunt ended) rod into the can from the hole end and push out the membrane until you can pinch it.

Some other stretchy latex device which has a little bulb at the end might be easier to get hold of, but I can't think of such an item, can you?

When you let go of the membrane with it stretched out as far as you can go, what happens?

Well, if you made the small circular hole at the metal-plate end of the cylinder nice and clean and central, the cannon fires a coherent vortex of air.

What do I mean by a 'vortex'?

Imagin a ring doughnut compromised of air shooting out of the end of the tube like a smoke ring out of a Hobbit.

The vortex is spinning. Not like the bullet fired from a rifled barrel, but as if it is constantly trying to turn itself inside-out.

This spinning keeps the torus (this is what the shape of a ring doughnut is called) coherent and intact for several feet.

If you made the hole in the metal plate end of the tube nice and clean, and you stretched the balloon membrane out as far as you possibly can, the cannon is capable of blowing out the flame of a candle at about ten feet (three metres) in the still air in a room.

As soon as it leaves the cannon, the vortex will begin to degrade and fall apart.

A word of warning

This little toy might only be firing a torus of air, but do not be tempted to shoot yourself or the cat in the face at point blank range. It hurts.
