Best software to manage patching including Oracle

My organization has some applications that need a Pre and Post action applied when a server is patched. What software do you use to manage this at at your organization? For example: Oracle needs to have the database shut down prior to any patching occurring.

btrfs performance on a development machine

Is anyone using btrfs on a development machine? It seems that it had (has?) some performance issues for database workloads, so I'm wondering how that compares for the typical development workload.

wipe 2 hdd simultaneously via ssh

Hallo

How can i wipe 2 hdd simultaneously over ssh ?

I always used dd

`dd if=/dev/zero of=/dev/sda bs=1M status=progress`

`dd if=/dev/zero of=/dev/sdb bs=1M status=progress`

or

`dd if=/dev/urandom of=/dev/sda bs=1M status=progress`

`dd if=/dev/urandom of=/dev/sdb bs=1M status=progress`

​

however, both commands takes too long to complete

​

is there a possibility to wipe both hard disks quickly and simultaneously?

Service stops working as soon as I close SSH connection

I have a Raspberry Pi with Raspbian Buster Lite. There's a service running to relay messages. Called NKN. Shouldn't really matter though. I run it headless and connect to it with putty. When I close putty and reconnect it asks me for my login and password like always and then there's nothing running. How can I keep it running?

Gnome has awful window placement.

It tries to mix tiling and floating window managers and creates the worst of both worlds. More often than not it's opening new windows in the top left corner, very distracting and annoying on my ultrawide.


I know you can change it to open new windows in the centre but that's only slightly better. Remembering the position the previous windows were closed in is the best way for a floating wm to work.

My Linux Journey So Far (Simplified)

I've actually never in my life had a Windows OS installed on any of my machines. I'm 14 and my dad had me using a Debian XFCE PC when I was around 7 or 8. I didn't really actually know anything apart from playing games and basic web browsing, but about 2-3 years later I had a new computer with Ubuntu 16.04 and he \*finally\* gave me root privileges. Broke my install later that night. After this, I started actually learning how to manipulate the system without messing it up. During this time, I stayed within the bubble of what I knew: Debian based Distros (Mainly because of I LOVED apt and dpkg). I think it was in the middle of last year that I tried out Arch and I LOVED it. Pacman was SO much easier than apt and I had access to the AUR which was awesome. I removed xUbuntu from my system and switched full time to Manjaro (mainly because it just works with very little troubles and all the goodness of Arch). That brings me to where I am today. My dad bought me a fantastic Thinkpad T510 a few months ago. I've been using my current Manjaro GNOME install for OVER A MONTH NOW! Very stable and productivity is fantastic. I've learned a lot on my journey including some basic understanding for programming languages like C, Bash (love it), CSS, Python, and HTML. I would not choose ANY operating system over Linux and I'm very happy that my dad was into Linux and the Open Source world and passed it on to me. Now I think he regrets it, though, because it's all I ever talk about.

Cheap laptop to run Ubuntu on

So my 10 year old MacBook Pro finally died a few days ago. I am now looking a for a cheap used laptop (probably something like a thinkpad) in the price range of 100-150 EUR to run Ubuntu on. I don’t need much processing power, as I only use it for web browsing and SSHing into my servers. What would you recommend at that price range?
