HPR4138: Linux Gaming: Factorio
This show is about gaming, more specifically gaming on Linux. This
episodes is about Factorio, a survival strategy game focusing on
automation. I currently don't have show notes to go with this show. -
HPR4137: I used reisub key sequence to reboot my frozen Linux computer
In two earlier episodes I have been talking about digiKam photo
management software. I hope to come back to that topic in another
episode in the future. But not today.
Today I will talk about what happened to me about two weeks ago.
Maybe it was because I had used the hibernate state, which I rarely use,
that caused my laptop to behave somewhat strange. So I decided to turn
it off. It was my Lenovo Thinkpad T460p laptop, running Linux Mint
Debian Edition.
So I turned it off the normal way with the soft button inside the
operating system. But instead of power off I was shown a full terminal
screen with a lot of text what it was doing. But it never came to the
conclusion to turn off.
I have learned that in those situations, although tempting, that on
Linux I should not force turn off with the physical mechanical power
button. I have tried that before on another Linux laptop, and it was not
a success, rather the opposite.
What I should do with Linux is to talk with electrodes directly to
the central brain, or in other words, call the Linux kernel with help of
a system request and by that sidestep the operating system.
A System Request is done with the SysRq key on the keyboard. In this
situation I did the reisub key sequence with a system request:
If I hold the System Request key together with the Alternate Alt key,
and when still holding them down, I type the letters r, e, i, s, u and
b, one by one in a very slow pace, I take seconds between them. Then I
release all keys and the machine reboots.
This was very successful for me and the laptop has since then worked
as normal.
I use an external full size keyboard that has a System Request
key.
But not all laptops has such a key any more. System Request can be
reached also on all or most of those laptops with some key combination.
But that key combination varies between manufacturers and models.
In the show notes I add a link to a How to geek article about reisub
as well as to Wikipedia about System Request:

HPR4136: Pi Samba Share
We live in a time where everything is streamed; from our TV, radio,
podcasts everything is fine until the internet goes down. Gone are the
days of simply turning on the TV with a set top aerial. With this in
mind, I set up an old Raspberry Pi 2 and connected it to use as a video
and music server through a Samba share.
To complete this task you will need:
A Raspberry Pi
A micro-SD card
An Ethernet cable
An external hard drive (min 2TB recommended)
Step 1: Update your Pi software in the terminal:
sudo apt update && sudo apt upgrade
Step 2: To allow us to share our files over a network we will install
Samba:
sudo apt install samba
Step 3: To find UUID and the file system of the drive, enter:
sudo blkid
Ignore the line with fat32, this is your Micro-SD
card.
Step 4: We need to mount this drive automatically whenever the
Raspberry Pi is switched on. Firstly, we'll need to create a location to
mount the external hard drive, we can do this by using the command:
sudo mkdir /media/external
Step 5: Now we need to edit the fstab to tell the Raspberry Pi to
automount the external drive every time it is switched on
sudo nano /etc/fstab
Insert the following line at the bottom of the page:
UUID="{the UUID you noted down in step 3}" /media/external {type noted in step 3} auto,user,rw 0 0
The above should all be on one line, pressing the tab key to create a
gap between each piece of information.
Step 6: Now we need to set up which folders are going to be shared.
I'll assume that we are going to make the whole of the external drive
available over the network
sudo nano /etc/samba/smb.conf
At the bottom of the page add the following, note that you can call
this anything you wish, just exchange the word external but you must
include [ ]:
[external]
path = /media/external
available= yes
browsable = yes
public = yes
writable = yes
It's worth noting before we continue that I've set the option
writable = yes, this means that you can add to or remove
the contents of the external drive over the network. If you are not
comfortable having this option then simply change it to
writable = no. Now save and exit (ctrl + X), make sure that
you answer 'yes' to save your changes.
Step 7: We will now set the Raspberry Pi to log in automatically on
startup, if the user Pi isn't logged in then all of things we've just
set up will not work. Type:
sudo nano /etc/inittab
Navigate down to the line:
1:2345:respawn:/sbin/getty --noclear 38400 tty1
and add --autologin pi after getty to make
the line:
1:2345:respawn:/sbin/getty --autologin pi --noclear 38400 tty1
Save and exit (ctrl + X) make sure that you answer 'yes' to save
it.
Step 8: We can try it out our system and auto-login by using the
command
sudo reboot
Assuming that everything goes well, your system should be up and
running. Try and find it on a computer through the file manager. I
personally recommend saving the Pi location on Kodi for an easy to use
solution for browsing your media on a TV. -
