Re: [Solved] rpi0w freezes if Wifi comes back

The issue is long fixed with official binaries. I use a few PIs (3 and Zero W) in Wifi and none freezes. A Pi Zero W is working for month stable. Data is requested over Wifi every minute. It also fetches data every minute. How do you know the system freezes? Did you connect via serial console to see...

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.

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...

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?
