MX Backup – Postfix Email Server | samhobbs.co.uk

Posted by jpluimers on 2017/11/09

Interesting as it has steps for both OpenSuSE and Debian each well suited for running on a Raspberry Pi.

[WayBackMX Backup – Postfix Email Server | samhobbs.co.uk

It seems postfix is a lot easier to configure than sendmail so I already like it.

First I need to read a bit more in Postfix greylisting.

I’ll need to catch up on Sam’s other parts with the postfix tag as well:

ModMyPi | Cluster HAT Kit Inc. 4 x Raspberry Pi Zero

Posted by jpluimers on 2017/10/30

Interesting stuff; I wonder if there is a case for it as well:

The Cluster HAT interfaces a (Controller) Raspberry Pi A+/B+/2/3 with 4 Raspberry Pi Zeros Configured to use USB Gadget mode, it is an ideal tool for teaching, testing or simulating small scale clusters.

This Kit Includes 1 x Cluster HAT V2, 4 x Raspberry Pi Zero’s, 4 x 16GB Micro SD Cards.

Please Note. A Raspberry Pi B+/2/3, with SD Card & Power Supply are also required for set up. These items are NOT Included in the Kit but can be purchased separately.

UPS PIco HV3.0 documentation not on github: “03_0x38_W_UPS PIco HV3.0.pdf”

Posted by jpluimers on 2017/10/17

I ordered a UPS PIco HV3.0 A Stack 450 Plus and it arrived without any documentation on how to solder the parts together.

So I tried searching for them: https://www.google.com/search?q=UPS+PIco+HV3.0+A+Stack+450+Plus+installation+instructions which turned mostly github based URLs.

I learned there is a bit on github:

But despite code and documentation being there, no installation instructions on how to solder the stuff together.

Luckily, they responded quickly to my tweet So I got my “UPS PIco HV3.0 A Stack 450 Plus” @ModMyPi but no assembly instructions. Where do all the non-soldered parts go when using RPi3? and a quick respons thread revealing I needed 03_0x38_W_UPS PIco HV3.0.pdf which – TADAAAA – is on Google drive and on the forums at [WayBackUPS PIco Firmware Update & Troubleshooting : Technical Support

So despite github providing an excellent platform for discussion and storing documentation, something archaic like a forum is used to store data in a disorganised way.

Too bad, as the document itself is 100+ page of invaluable documentation.

So in case of future bit-rot, here are the links:

Raspberry Pi brexit – changing your locale away from GB when you’ve a different keyboard

Posted by jpluimers on 2017/10/02

A while ago I wrote about -bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) on fresh Raspbian on Raspberry

I thought my locale issues were solved and they sort of were. Until I had to logon locally and managed to get one or more of these characters in my password:

  • ~ (tilde)
  • @ (at)
  • # (hash)
  • \ (backslash)
  • | (pipe)
  • " (double-quote)

Then logon would fail locally but work via ssh. Go figure!

Lot’s of people outside the UK using their Raspberry Pi with keyboard and monitor will now say: you’ve the default GB keyboard layout and your keyboard is not GB.

Bingo!

This is how US keys look when using a GB keyboard layout:

This was after updating my Raspberry Pi 3 with Tumbleweed to 20170920.

Not sure what do do now. Some searches didn’t reveal much:
