I wrote this a long time ago as a proof-of-concept for a vaporware project. Recently I have had the need to something which seems easy at a high-level standpoint, but is actually quite hard to implement.

The original purpose for this concept was to easily maintain a strict order of data held within the rows, while still having the option to reorder the rows in an efficient manner (one table, no joins, no special embedded scripts etc).

A little insight into what I was doing: I once worked on a network security team for a tier-1 ISP. A coworker and myself had already written some really nice code to deal with the thousands (yes, thousands) of firewalls we dealt with on a daily basis. We created an API which generated abstracted structures of firewall configurations; by abstracting I mean creating a singular data-structure which represented rules, and rule-sets (a nice side-effect of this method was we could morph one firewall syntax structure to another. E.g., juniper filters -> netscreen rules. Needless to s

Mouse and Keyboard power off

Do you use an usb mouse and keyboard and have laptop_mode installed under your Arch linux ? Then maybe you have the same problems as me - mouse and keyboard getting inactive every 2 seconds or so.

To solve this, go to /etc/laptop-mode/conf.d and copy usb-autosuspend.conf to /etc/laptop-mode/conf.d/board-specific. After that run lsusb and get the ID of the usb device you want, e.g., 093a:2500 .

Open the board-specific/usb-autosuspend.conf file and find the AUTOSUSPEND_USBID_BLACKLIST conf option. Put the desired usb IDs there. You might need to run sudo laptop_mode afterwards to reload the configs.
