PiHole - advertisement & tracking blocking (also runs on the even faster odroids) can speed up surfing +50%

let’s face it: the internet has become a gigantic surveillance machine, with hundreds of private companies, trying to collect as much data on the user as possible in order to “predict the market” while also using with AI to analyze “BigData”.

Advertisement is MORE than annoying, it is a massive privacy issue, which makes millions of web users install the excellent

open source ublock firefox addon (“full spectrum blocker”) but there is even ads & tracking blocking “in hardware”:

hurray hurray, South Korean company Odroid (well known for their beefy (performant while using less than 5Watts!) Raspberry competitors) just released “Odroid” “M1” (not getting a penny for this) for little money:

which can be EU shipped from here: https://www.pollin.de/p/odroid-m1-einplatinen-computer-4-gb-ram-811474

imho EVERY modern day firewall needs to include advertisement & tracking blocking PER DEFAULT 🙂

„Müsste eigentlich 7,30 Euro kosten“

„Ein Döner müsste eigentlich 7,30 Euro kosten“, sagte Gürsel Ülber, Vorstandsvorsitzender des Vereins türkischer Dönerhersteller. Gestiegene Preise für Energie und Lebensmittel setzen der Imbissbranche zu, es gibt Lieferengpässe beim Speiseöl. http://www.taz.de/!5849384/ #taz #tazgezwitscher #tageszeitung #Döner #Fast #Food

Döner wird teurer – Fritten und Burger auch: „Müsste eigentlich 7,30 Euro kosten“

Gestiegene Preise für Energie und Lebensmittel setzen der Imbissbranche zu. Und die Betriebe klagen zunehmend über Lieferengpässe beim Speiseöl.

GNU Linux Debian - very fast and easy semi-automatic online install Debian 11 (non-free)

many users have/had macbooks.

what was/still is great: OSX can be reinstalled over internet! (no more searching for licence keys or setup sticks/DVDs/CDs/)

given the fact – that once installed – GNU Linux Debian can boot (almost) anywhere, the fastest and easiest way to “install” it is to simply 1:1 copy it on whatever the user wants to boot from (harddisk or usb stick (some sticks can not be made bootable, try at least 3 different vendors)).

So… this install script 1:1 copy installs Debian 11 (non-free) on any laptop/desktop/server (depending on internet speed) very fast & easy.

The process can be automated (on similar hardware or on hardware where /dev/sda is always the device the user wants to 1:1 overwrite).

This script install process is almost like OSX 🙂 but “semi-automatic” to double ask, not to overwrite the wrong (USB attached?) disk.

  • it comes with a full MATE Desktop and everything to get working (LibreOffice and Firefox and Thunderbird)
  • it has the “cosmos” slideshow (love it!) background enabled per default
  • the terminal comes with green on black for better readability
  • it does not have a swap partition enabled, so the user can easily with gparted 1) extend the harddisk to it’s full capacity 2) create a swap partition
  • English, Spanish, Chinese and German keyboard layout are active, should be possible to switch between them in the top right corner

todo: what is still missing

  • what is still missing is:
    • automatically calc (based on RAM size, would do as much swap as RAM) how much swap should be created
    • extend the /root partition to full harddisk capacity minus the swap space
    • create the swap partition and edit config files /etc/fstab and /etc/initramfs-tools/conf.d/resume for proper (as intended) functionality of the system
  • apply this
  • display a dancing penguin during first successfull boot and encourage user to do at least 5min of dancing to this funky music 🙂

WARNING!

  • make sure to disconnect all devices (external harddisks, usb sticks, sdcards)
    • less devices = less trouble and less accidentally overwriting a external harddisk or usb stick
  • if the target device /dev/sdX contains important data, backup it up !first! (all data will be overwritten)

WHY NON FREE?

it’s based on the non-free version, because it is intended to allow new users that never tested GNU Linux Debian (with a MATE Desktop) a “it just works” turnkey experience.

Is the Free version better?

If the user has concerns about surveillance/spying and needs maximum privacy than it is probably better to start with the defautl GNU Linux Debian free version and usually all network-cards/NICs work out of the box (free drivers available 🙂 (but maybe not the wifi cards)

new users: workaround for this pitfall:

https://dwaves.de/2022/01/21/gnu-linux-debian-11-2-network-stops-working-networking-stops-during-setup-bad-archive-mirror-how-every-os-setup-should-be/

Problems might arise with the free version and wifi: (notebooks)

because then the user will probably have to install the appropriate closed source (#evil!) drivers from the the non-free repository with all the spying backdoors that a intel wifi driver might have (after all a network card, is like a small computer, inside a computer, ideal! but then if the BIOS is not LibreBooted… the Intel ME can not be disabled… (some OS allow to permanently disable Intel ME!!!).

… the fight for more privacy and security – seems never ending and goes on.

requirements:

  • the laptop/desktop/server root harddisk/the target harddisk (/dev/sdX) should have at least 100GBytes of harddisk space
  • ideally boot from GNU Linux live usb stick with at least 3GBytes of free space

  • or alternatively: boot from read-only live DVD or image and when booted up, connect a ext4 or ext3 or fat32 or ntfs formatted USB stick or drive with at least 3GBytes of free space

    • there are many other desktop live flavours available (great! 🙂 : https://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/
    • when booted from live, cd into the external usb stick-drive
    • create the below script (copy content into a text file, name it name-of-script.sh)
    • <span style="color: #00ffff;">chmod +x name-of-script.sh</span>; # mark it runnable - <span style="color: #00ffff;">su - root</span>; # become root
    • <span style="color: #00ffff;">/name-of-script.sh /dev/sdX</span>; # run it, passing the device Debian 11 should be installed on - will download ~2.5Gbytes image.gz to current directory (the usb-stick-drive and store it there permanently for later re-use) - curl can resume interrupted downloads

usage:

# sdX is the device the user wants to install Debian 11 on
<span style="color: #00ffff;">/scripts/install_debian_from_image.sh /dev/sdX
</span>

process complete? reboot & “it just works”?

congratz! do 1min of wiggle dance!

post processing:

want to use the complete harddisk not just the 100GBytes? two possibilities:

what the script will do:

  • download a pre-installed Debian 11 image.gz and it’s sha512check-sum
  • sha512 check the image (check the image is unaltered and intact)
  • on the fly unpack and 1:1 write the image to /dev/sdX while showing a progress bar
