Here is how Ifixed it on a Mint/Ubuntu install
1.) First download the latest AMDGPU-Pro driver from here:

Navigate to your relevant video card:

One issue is that by default they give you a version for the latest version of........
If you are using mint, delete the preference that stops snap from installing (as it is required for lxc)

Debian at this time does not have lxd so you'll need to use snap:

Just edit your ~/.bashrc and add this at the very end:
export PS1="realtechtalk.com"
Then your prompt will look like this:

If you wanted a dollar sign at the end then you would change it like this:

1.) gg and dG
The easiest way is to type "gg" to bring yourself to the first line of the file and the "dG" clears the contents.
2.) :1,$d
Hit Escape and colon and then type: 1,$d and all contents / lines of the file will be cleared.........
Just a quick note and warning is that if you are testing to see if EFIPXE booting works on a VM, MAKE SURE it actually works. For example Iinitially tested using my Distro's QEMU 2.5+dfsg-5ubuntu10.46 and ovmf BIOS firmware (OVMF supports EFI). However, I found on old versions of QEMU (like 2.5), EFIbooting with GRUB NEVER works so it may appear that you have made a mistake when everything is fine when you boot a physi........

This is only really necessary in the case you don't want DHCP. If you are dealing with an encrypted LUKS server on the internet, you will often want to have a static IP so you know which IP to connect to (or if you have a semi-static IP assigned by DHCP).
SET IP Address by /etc/initramfs-tools/initramfs.conf
IP Address=192.168.1.27
Gateway=192.168.1.1

Yes you have that right, the network service in RHEL8 / CentOS 8 / Rocky Linux / Alma Linux no longer exists. So there is no more systemctl restart network
You can restart NetworkManager but it doesn't have the same effect or ifup/ifdown on all interfaces.
Generally if NetworkManager is installed you will want to restart it or it won't apply the settings from ifcfg.
systemctl restart NetworkManager

The easiest way to know if your videos are playing with GPU acceleration are to watch the process of xplayer, mpv or whatever you are playing. The CPU usage should be no more than 10% for that process/program if it is using acceleration.
Let's manually play with vdpau to make sure it works before we make it permanent:
First make sure you have libvdpau installed:

Most of us know the heredoc method but what if you need a basic query done repeatedly and manually while working from bash? It is a pain to manually type mysql and login each time.
With this command below you can semi-automate those queries:

Just modify the above to suit your needs and you can add more queries by adding a sem........
Install Errors on Version 12:
This error happened on QEMU emulator version 2.11.1 pve-qemu-kvm_2.11.1-5
on Proxmox/Debian but installing on QEMU.12 on Centos 6 did not produce the error.
*Update it is not related to the OS or QEMU version. This happened in Centos 6 too after a second install.
What really causes this even though you successfully install........
initiator = client
target = server
These are the first concepts you should understand which is that in iscsi essentially the "initiator" is the client and the "target" is the server.
iSCSI is derived from the old fashioned SCSI that us oldtimers grew to love. The "i" stands for Internet and the SCSI stands for "Small Computers Systems Interface" (SCSI).

This is not the normal "black screen"issue and I was shocked to eventually find out why. The normal advice of reconfiguring Xorg didn't work. Even booting into "Recovery Mode" did not help.
Here is the short end of the stick that fixed it:

What if you want to mass rename them?
the rename tool can work just like sed
For Debian based distros:
Note "file" is what we search for and "newname" is what we replace it with, so substitute according to your requirements.

This issue was annoying basically it seems like a libgd issue/bug with newer versions of PHP and it was difficult to trace-out. One very useful thing that helped me was using "php-cgi" and passing the query string as an argument eg:

It's actually fairly straight forward:
load data local infile 'billpayments-payments.csv' into table payments
fields terminated by ','
enclosed by '"'
lines terminated by 'n'
The above assumes that your fields are terminated by a comma (some programs like OpenOffice change this to a semi-colon ;) and that they are enclosed with "

There are all kinds of threads and links on the internet, and this seems to be a contentious issue butI don't know why.
95th percentile is either a good deal for some or a big rip off for others, Ijust said it there :)
But the reality is that for MOST people who transfer low amounts of data but burst to higher speeds such as 40mbit+ even for short periods of time, then you'll pay a lot of money to do that.
Basically 95th percentile is an-old archaic method........
Basically you should always be 100% sure that whatever IPyour mail server sends out with has reverse DNS/PTR records. Remember that unless you own your IPs then you won't be able to set your own reverse DNS. Even if you were to create a reverse PTR record on your DNS servers it will be ignored. Reverse DNS is queried to pre-assigned DNS servers of your ISP, so therefore you'll need to contact your ISP/Colo/Hosting provider to do a reverse DNS entry.

This is a great way to use your ftp server space, for example on your web hosting account (althoughI believe many hosts don't allow storage like this), but if you have a VPS/Dedicated Server etc.., this would be perfect. Imagine how easy it is to work with an ftp account that you can just mount as a normal partition or directory in Linux, it would be great for backups etc..
