Reminder to self – did “Clear App Data” get me any Google Opinion Rewards surveys?

Posted by jpluimers on 2017/01/20

Somehow I didn’t get Google Opinion Rewards surveys for more than half a year. As per below post, I’ve cleared the app data a week ago.

This is a reminder to myself to check if I got any surveys since…

(Yes, I’ve location on, battery saving off and the app runs).

Linux Storage Stack Diagram – Thomas-Krenn-Wiki

Posted by jpluimers on 2017/01/20

There are lots of old copies floating around from the Linux Storage Stack Diagram – Thomas-Krenn-Wiki.

The above link has the up-to-date version and larger versions in PNG, SVG and PDF so be sure to check it out.

The old URL was http://www.thomas-krenn.com/en/oss/linux-io-stack-diagram.html – it now redirects to the above one.

Some older copies that got me looking for the new one:

linux port forwarding to external ip – Google Search

Posted by jpluimers on 2017/01/20

For my Link Archive via linux port forwarding to external ip – Google Search:

Need to look at this more closely, but it looks like you need PREROUTING, FORWARD and POSTROUTING and two NATs (DNAT and SNAT), as this graph from Port Forwarding Using iptables – SysTutorials shows:

PACKET IN
    |
PREROUTING--[routing]-->--FORWARD-->--POSTROUTING-->--OUT
 - nat (dst)   |           - filter      - nat (src)
               |                            |
               |                            |
              INPUT                       OUTPUT
              - filter                    - nat (dst)
               |                          - filter
               |                            |
               `----->-----[app]----->------'
