Sometimes you want to create a quick snapshot of a few files / folders. rsync is a great tool for this. And sometimes you don’t want to copy the files because that takes up space and you might be copying them to the same filesystem. Hardlinking is quite a nice option in this case (if the filesystem supports it)

Add a new certificate in unify controller
I’m making use of Ubiquiti AP’s and therefore use the Unify software to manage them. I have it installed within an “ordinary” vm.
The software normally uses a self-signed certificate. This is not a big issue as it is my local network.
However Chrome starts warning more and more and Safari doesn’t seem to like the self-signed certificate at all after the latest updates. So it became time to install a “proper” certificate.
This little article explains how.

When running code you sometimes have the need to debug the progress of the statements. One way is to use a table and write your debug output into it by means of an autonomous transaction. But sometimes it can be easier to just hand the debug info to a different session. Say hi to Dbms_Pipe…

Sometimes you need to resize a filesystem because it grows out of it’s available space. With virtual machines this is quite easy, just resize the disk. But…. how do you make Linux know the disk has been resized?

As I read an article about Oracle providing version 23c “for free to developers” (https://blogs.oracle.com/database/post/oracle-database-23c-free) I wondered if it was usable for a quick deploy of Apex. As ORDS has been updated as well it turns out that needed some tweaking…

For my audio system I’m making use of Logitech Squeezeboxes, as I’ve converted most of my CD’s (yes I’m old ;)) to MP3 format. In this way I’m able to play/stream the same music throughout my house. Spotify is also integrated into this set-up so I’m able to play that as well.
But I also have a record player (old remember ;)) with vinyl records. It would be nice to play them through the same system….
UTM as a makeshift Vagrant replacement
It’s almost becoming a series about UTM, my quest of finding replacements for tooling I used on my Intel based MacBook Pro. This time a little article about how I’m using UTM as a replacement for my usage of Vagrant.

When buying a new laptop I settled for a MacBook Pro with a M2 processor. As I was used to an Intel based MacBook Pro with virtual machines and Docker containers I keep searching for replacements for the functionality I was used to. Earlier I’ve written a blog post about running an Oracle Database on the M2 MacBook pro, this time I’d like to talk about using x86 based containers.

With the newer versions of macOS the Wifi of your MacBook is being enabled automatically when the laptop is being restarted. This might not be something you want.

Starting with macOS Ventura, Apple in all its wisdom seems to have removed the scheduling possibilities for sleeping and waking your MacBook from the power options.
