  • Every time I think about hosting my own mail server, I think back to the many, many, many times I’ve had to troubleshoot corporate email systems over the years. From small ones that ran on duct tape and prayers to big ones that were robust, high dollar systems.

    98% of the time, the reason the messages aren’t coming or going is something either really obscure or really stupid. Email itself isn’t that complicated and it’s a legacy communications medium at this point. But it’s had so much stuff piled on top of it for spam and fraud prevention, out of necessity, and that’s where the major headaches come from. Honestly, it’s one service that to me it’s worth paying someone else to deal with.




  • Reviewing large PR’s is hard. Breaking apart large PR’s that are all related changes into smaller PR’s is also hard.

    If I submit a big one, I usually leave notes in the description explaining where the “core” changes are and what they are trying to accomplish. The goal being to give the reviewers a good starting point.

    I also like to unit test the shit out of my code which helps a lot. The main issue there is getting management to embrace unit tests. Unit tests often double the effort up front but save tons of time in the long run. We’re going to spend the time one way or the other. Better to do it up front when it’s “cheaper” because charging it to the tech debt credit card racks up lots of expensive interest.






  • Set up a VPS. Create a VPN tunnel from you local network to the VPS. Use the VPS as the edge router by opening ports on the VPS firewall and routing incoming traffic on those ports through the VPN tunnel to servers on your local network.

    I used to do this to get around CGNAT. I ran RouterOS in a Digital Ocean droplet and setting up a wire guard tunnel between it and my local Mikrotik router.

    It will obscure your local WAN IP and give you a static IP but that’s about the only benefit. And you have to be pretty network savvy to configure it correctly.

    It does not make you immune to DDoS attacks and is honestly more headache to maintain (albeit just a small headache).
