The turtle and the cat

 A turtle was walking on a field when it gets spotted by a cat, who quickly approaches it. 

"What's this?" — asks the cat, looking at the turtle, now hidden in its shell. "I could have sworn that I saw it move" and it starts touching it with its paws.

"Please Mr. Cat, I only want to go home" — says the turtle, "Please let me go and I'll be on my way".

The cat ignores the turtle and continues to walk around it, touching it and even trying to get to roll over. The turtle, now upset, notices the cat's tail in front of it and bites it as hard as it can.

The cat screams in pain and runs away as far as it can from the turtle, who starts moving to its home again.

...what we need to is: 

     sudo nano /etc/NetworkManager/conf.d/20-connectivity.conf

Add the following to the file:

[connectivity]
.set.enabled=false

Then save by pressing CTRL+O, then Enter, and exit by pressing CTRL+X. Restart NetworkManager using

     sudo systemctl restart NetworkManager

and that should be it.

The good news is that the driver is in the kernel, the bad news is that it very aggressively checks for connections. There are alternative drivers for Arch and Ubuntu (like this one on GitHub), but why change it when the default drivers is good enough.

That same link has an important tidbit that we could use. How to disable the periodic scanning.

We are going to disable the Connectivity Check option in NetworkManager. This by editing the file in /var/lib/NetworkManager/NetworkManager-intern.conf and adding the following instructions at the end:

[connectivity]
.set.enabled=false

However, that's a system file and you will lose the configuration next time NetworkManager updates or restarts. 

 

Instead, what we need to is: 

     sudo nano /etc/NetworkManager/conf.d/20-connectivity.conf

Add the following to the file:

[connectivity]
.set.enabled=false

Then save by pressing CTRL+O, then Enter, and exit by pressing CTRL+X. Restart NetworkManager using

     sudo systemctl restart NetworkManager

and that should be it.

How to remove HDR from videos using Handbrake

 Go to Filters > Colorspace, then select BT.709 from the dropdown menu. Remember to check the preview before converting. 

 

 

Note: Do not encode 4K video on a laptop unless you want to do a hardware test. I only recommend you to try if your laptop's GPU has an actual model name.

Day 1: Learning Python Journal

 This is cheating since I started practicing using "Learn Python the Hard Way" by Zed Shaw a couple of days ago, but this is the first time I actually write so Day 1 it is.

 So far, I've done exercises 1 to 12. I set the goal to do three exercises per day, which I'm failing horribly. The important thing here though is to never fully abandon it and to remember that it's only hard at first. 

The first 12 exercises are the very basic of working with Python within Python: numbers, operations, characters, input and output. From what I've glanced from chapter 13 is that we're finally going to handle files. Very important so we can keep information long term, instead of the short term we've been dealing with so far. From the sneak peek in chapter 12, I'm going to learn how to make system calls using file, os, sys, and can't remember what else. Don't understand the difference either, but the book says that it's ok for now; I sure hope so.

Enough introductions, I'm going to start exercise 13, and if everything goes well, exercises 14 and 15.
