JavaUseReducedSignals wiki posting

A few days ago after discussion with Lotus Devs I created (my very first) Domino wiki posting about JavaUseReducedSignals notes.ini variable.

More details on this link:

It's a workaround for a known problem with having Domino started up in SSH session, hope someone will find it useful.

Clearing (disabling) swap on Ubuntu

Today I was searching for ways of improving performance (memory/disk IO) on my Ubuntu desktop after running some application with extensive memory requirements - e.g. VirtualBox instance, I found that a bit of swap space (10%) remained in use, which was downgrading the overall system performance (any new application/windows = IO). Following commands that helped to offload previously paged data back to the RAM:

> sudo swapoff -a
> sudo swapon -a

Note:
Command to recreate swap partition: sudo /sbin/mkswap /dev/<e.g. sda4>
