If you’ve seen following error while emerging some package, than be sure this is a bug in portage. Just append to make.conf, and it should work again.
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. Fix is simple: correct /etc/hosts file on affected node check with ping that node name returns […]
Getting filesystem quotas work inside of a LXC unprivileged container is relatively a big problem, because linux kernel and LXC currently play against us (= they do not support this yet). But, workaround exists !
Quick how-to for registering and unregistering partitions on LVM logical volume (yes, event that is possible ;).
As always with Oracle its pretty ‘easy‘ and ‘straightforward‘ – you have to convert the high_value to XML and then extract it using XPATH (omg!). Let me guess, it would cost a fortune to provide native function/view that could do that…
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)!

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 […]
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).
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.
