This tutorial describes how to install TLS to a mail server consisting of Postfix and/or Dovecot by using Let's Encrypt certificates with automatic renewing and firewall management.
The system used for this tutorial was:
$ lsb_release -idrc
Distributor ID: UbuntuThis gist will show how to setup Raspbian Stretch as a headless Bluetooth A2DP audio sink. This will allow your phone, laptop or other Bluetooth device to play audio wirelessly through a Rasperry Pi.
A quick search will turn up a plethora of tutorials on setting up A2DP on the Raspberry Pi. However, I felt this gist was necessary because this solution is:
| zfs create -o volblocksize=32k -V 10G tslpool/iscsi1 | |
| zfs set sync=disabled tslpool/iscsi1 | |
| targetcli | |
| block/ create name=block_backend dev=/dev/zvol/tslpool/iscsi1 | |
| cd /iscsi | |
| create iqn.2017-11.com.mydomain.ad.zfstest:iscsidisk1 | |
| cd /iscsi/iqn.2017-11.com.mydomain.ad.zfstest:iscsidisk1/tpg1/acls | |
| # create acl with the initiator (client) name here, not the one you just created | |
| create iqn.1991-05.com.microsoft:dc1.ad.mydomain.com | |
| cd iqn.1991-05.com.microsoft:dc1.ad.mydomain.com |

This is a guide that I wrote to improve the default security of my website https://fortran.io , which has a certificate from LetsEncrypt. I'm choosing to improve HTTPS security and transparency without consideration for legacy browser support.
I would recommend these steps only if you have a specific need for information security, privacy, and trust with your users, and/or maintain a separate secure.example.com domain which won't mess up your main site. If you've been thinking about hosting a site on Tor, then this might be a good option, too.
The best resources that I've found for explaining these steps are https://https.cio.gov , https://certificate-transparency.org , and https://twitter.com/konklone
This has become a full-blown project, see: https://github.com/bemasher/rtlamr-collect

My SmartThings multisensor is a great little piece of technology. It reports, in real time, motion, temperature, and open/close state of my back door. The iOS app is slick, too, but I wanted a way to view it from my computer and have access to historical data.
Enter Dweet and Freeboard from Buglabs.
There's actually no setup required on Dweet (but be sure to check out their nifty demo). It just starts eating data and making it available for use via HTTP/JSON!
