<WRAP box>
There are certain Pi commands which can be used whenever you boot up your Raspberry Pi or between some of the codings. That does not mean you have to write them in the Raspberry Pi terminal every single time though.

apt update

apt upgrade

date (shows the current date of your system)

find / -name mandip.txt (finds the file named as mandip.txt in your system)

raspi-config (open the configuration window on your Raspberry Pi where you can change the settings of your computer including the SSH settings)

    sudo apt update
    sudo apt install xscreensaver

When installed open from menu [Preferences] --> [Screensaver]
Click on [Mode:] and select [Disable Screensaver]

====== root password ======

<code>
The reason, if you’re using the standard “pi” user account, is that you’re not an admin user and 
you don’t have the password for the superuser/root account. This is not an issue if you’re at the 
command line, using “sudo” before your command executes it as the superuser. Not so in “X” (the GUI environment), there are two solutions I have seen on the Raspberry Pi forums:

Option 1: Reset the root password. At the command line, enter the command below and enter the new password (credit: spurious).
…to set the root password you could write:

“sudo passwd root”

====== Screen Saver On the Raspberry Pi Desktop ======

<WRAP center round box >
2018-10-31

By default, the Raspberry Pi Desktop does not have any easy-to-use screensaver software installed, although the screensaver is enabled. Firstly, you should install the X Windows screensaver application.

 sudo apt-get install xscreensaver

From <https://www.raspberrypi.org/documentation/configuration/screensaver.md> 

How do I make xscreensaver show a slideshow of images?
You do this by using a program that can display a list of images on the root window. One such program, glslideshow is included with xscreensaver. It displays a sequence of images, slowly panning and zooming through them, and fading smoothly from one image to the next. Just select "GLSlideshow" in thexscreensaver control panel, and enter the directory (or RSS URL) where your images live on the "Advanced" tab.
If you want to only run a slideshow, then select GLSlideshow in "Only One Screen Saver" mode. Otherwise, the slideshow it will be just one of the display modes that xscreensaver will select from randomly, and run for the length of time specified in the `cycle' preference.
If your graphics card is extremely old, you may find that glslideshow doesn't run fast enough. This is unlikely: any graphics card manufactured in this century should be fast enough. But, if you try it and it is slow, then you'll want to run a different program. Two good choices for displaying slideshows on very old machines with no graphics acceleration are chbg and xv. To use those, you need to add a line to the `programs' preference in your .xscreensaver file:

GLSlideshow:	Just select it from the list; and specify your image directory on the "Advanced" tab.
	default-n: chbg -xscreensaver -randomize   \
                -interval 0.30             \
                -R $HOME/images/         \n\
chbg:
xv:	default-n: xv -root -rmode 5 -random       \
              -viewonly -wloop -wait 30    \
              $HOME/images/*.jpg         \n\

====== Step 2: Installing Resilio Sync ======

From: https://help.resilio.com/hc/en-us/articles/206178924

2019-01-05

<code>
For Debian-based Linux (Debian, Ubuntu, Mint, Zorin, Elementary)
Create file /etc/apt/sources.list.d/resilio-sync.list to register Resilio repository:

echo "deb http://linux-packages.resilio.com/resilio-sync/deb resilio-sync non-free" 
| sudo tee /etc/apt/sources.list.d/resilio-sync.list
Add public key with the following command:

curl -LO http://linux-packages.resilio.com/resilio-sync/key.asc && sudo apt-key add ./key.asc
For Raspberry Pi 1
sudo dpkg --add-architecture armel
sudo apt-get update
sudo apt-get install resilio-sync:armel
</code>


2018-10-30

Make sure you have an ethernet cable plugged in to your RasPi, and fire up lxterminal (there is a shortcut on the desktop). We’ll need to download the binary for Sync. To do this, change the download directory:
cd /home/pi
Then download and unpack the binary archive
wget https://download-cdn.getsync.com/2.5.12/linux-armhf/resilio-sync_armhf.tar.gz
tar -zxvf resilio-sync_armhf.tar.gz
And finally, run the program:
./rslsync --webui.listen 0.0.0.0:8888
Now, we want to make sure Sync will run at startup. This requires an extra step. In terminal, change your directory to the config folder:
cd ~/.config/
Create a new folder called “autostart”
mkdir autostart
Now create a new text document. You can use the leafpad program that comes pre-installed. The contents of the text document need to be as follows:
[Desktop Entry]
Type=Application
Exec=/home/pi/rslsync --webui.listen 0.0.0.0:8888
Save this file in the newly created ~/.config/autostart as: syncstart.desktop

====== Raspberry Digital Signage ======

2018-09-04

Raspberry Digital Signage is an operating system designed for digital signage installations on the Raspberry Pi: it displays a full-screen browser view restricted to the resource specified.

It shows web pages from an Internet, local area network or internal (SD-card-contained) resource; there is no way to escape this view but rebooting the machine. It is a hacker-proof secure operating systems for indoor and outdoor use.

From <https://sourceforge.net/projects/raspberrysign/> 


Raspberry Slideshow is focused on quick-to-set-up image and video slideshows for the Raspberry Pi. 
Insert a USB key with image/video files or retrieval informations from the network and boot: the system will display a slideshow of them in a full-screen view.

From <https://sourceforge.net/projects/raspberrypictureframe/> 

Raspberry WebKiosk is designed for the cheapest possible web kiosks and multi-user web workstations deployments - use in cafès, offices, schools, hotels, hospitals, libraries and so on. It's a port of the powerful Instant WebKoisk/UB OS for PCs.

It is a browser-only hacker-proof operating system for Internet browsing purposes, which fully protects users' privacy. After every reboot, the browser will be kept back to the default state and user-downloaded files will be deleted.

From <https://sourceforge.net/projects/raspberrywebkiosk/> 

Note-taking app for programmers. 
Apps available for Mac, Windows, Linux, Android and iOS.
Built with Electron, React + Redux, Webpack and CSSModules.

====== raspi-config ======

<code>
Using the Debian-Wheezy Beta image, there is a configuration utility built in that makes 
this easy:

There is a utility called raspi-config. This runs on first boot if you're connected directly 
to the RPi. If you're over SSH you can run it manually using $ sudo raspi-config. (I think you 
can re-run the tool manually at any time).

    In only a year the number of operating systems for the Raspberry Pi has grown tremendously. 
    In addition to various flavours of Linux and Unix, builds of RISC OS, Plan 9 and even an Amiga 
    compatible offering are now available. Take a look below, there is sure to be something of 
    interest to one and all.
    
====== Use Raspberry Pi to Measure Broadband Speeds to Hold Your ISP Accountable ======

From: http://makezine.com/projects/send-ticket-isp-when-your-internet-drops/

<code>
This is actually something I’ve been doing myself for a couple of years, also using a Raspberry Pi 
stuffed in a corner of my network closet. Well, not the bit where I tweet my broadband provider. 
Instead my script is a bit more direct: It automatically submits a trouble ticket into their support 
queue.

====== Raspberry Pi Print Server: Setup a Network Printer ======

From: https://pimylifeup.com/raspberry-pi-print-server/

<code>
In this tutorial, I will be going through the steps on how to setup a Raspberry Pi Print Server. The 
process of getting the software installed is pretty simple, but configuring it and getting a Windows 
network to find the print server is a bit more of an involved process.
Setting up a print server is a simple way of bringing your regular USB printer to more modern standards
without you having to shell out hundreds of dollars.
