Re: what is remote GPIO

Can somebody give an example where this would be really useful? My imagination is to low to find a really useful case. I mean you need a RPI at the place where you want GPIO Pins so you can run your script as well on that PI.

Re: Mount with root partitin with discard option (why not done by default)

Thanks, good article. I'll stay with trimming by crontab fstrim.
As far as I know windows does a discard after each delete (at least since version 7 or 8). So Windows wastes performance here.

Mount with root partitin with discard option (why not done by default)

Raspian comes with ext4 which can be mount with discard option. With discard option the sd-card is told which blocks are free and so better wear leveling is possible. I wonder why raspbian comes not default with the discard option? You can issue sudo fstrim -v / to do it manually but why not automat...

Re: Why PIN headers instead of female PIN headers?

Have you ever tried to ben a pinheader, they are pretty sturdy! No, was just afraid of it, because some cables are hard to put on or remove and sometimes need quite a bit force. Unlike the fragile contacts in female headers, which can loose springiness, and can fail. Good point! and its unreasonabl...

The question to ask is do you actually need the newer version - are there features in it that you need? If so then look at one of the methods you can try to get the newer version.

Re: Request for update nullmailerpackage

Not going to happen. Debian (and also Raspbian) generally don't do version updates once a new major version (Jessie, Stretch) is released.
Ok, thats an argument, but in between 2013 and now there was at least Raspbian Stretch, perhaps wheezy, so it should have been updated, shouldn't it?

When installing nullmailer via sudo apt install nullmailer you geht version 1.13 which is from 2013 or even older. Current version is 2.2
Can you please update this about 6 year old package?

Re: OpenVPN can't write logfile to home folder

Thanks for your fast analyze.
This makes me think that the log path may be hard coded into the openvpn program along with instructions to lock down the log file from 644.
Just a hint. On other Raspberry OpenVPN also installed via apt get and same version, OpenVPN can write to home directory.
