Fix for Gentoo: The ebuild phase ‘die_hooks’ has been aborted

Fix invalid node IP in /etc/pve/.members
When adding new node to Proxmox Cluster, local system might pickup invalid local IP (usually public IP instead of internal, or IPV6 instead of IPv4) and use it in .members file, what results in 595 network problem error messages.

Quotas in LXC unprivileged container

Partitions of LVM logical volume
Quick how-to for registering and unregistering partitions on LVM logical volume (yes, event that is possible ;).
Extracting Oracle high_value from user_tab_partitions

PostgreSQL and user restrictive view with functions involved
In PostgreSQL it’s quite easy to restrict access for user to some tables: create restrictive view grant usage on view schema grant select on view to restricted user done Really easy. And it’s not working when the restrictive view, is selecting from another view that is using function(s)!

TINC VPN config generator

I find its configuration really tedious and complicated compared to OpenVPN and its possibility to centrally assign IP addresses and push options to clients. I know, that’s the tax for being mesh, but wouldn’t […]
Beelink Android TV box + Harmony remote
Here is my solution for making Amlogic S812 based Beelink MXIII Plus Android TV Box work with Logitech Harmony universal remote. It’s based on solution described on this forum post, but modified to make it easier to use (if your Harmony remote is able to learn new IR commands).
Selective routing on Linux
Sometime it’s needed to selectively route specified IPs or networks via different interface – i.e. if you want to route private addresses over VPN (a.k.a split tunnel routing) or to route some public IPs over VPN to unblock some nationally restricted sites (Netflix). Here are simple scripts to achieve this.
