I've spent years tweaking my mail server setup (Postfix, Dovecot, RSPAMD, LDAP...) and did a full writeup a few months ago. I've used other guides online but found most of the rest lacking on details.

This PDF might be news to many; click 'past' to see previous submissions -- last month's got traction:

HN user saulrh mentioned that the list of requirements "does not seem incredibly unusual" for enterprise setups with AMT on.

Pre-Meltdown/Spectre this was 2017's "big deal" re:Intel; nearly all of the varying degrees of paranoia in the previous discusson seem a lot more reasonable with the benefit of hindsight. (If any more AMT info has become available thanks to Meltdown/Spectre-enhanced reverse engineering I would appreciate a heads-up; example vs SGX: https://github.com/lsds/spectre-attack-sgx)

Of all the previous tmux discussions, the most practical help was given when this article was discussed 2 months ago:

Surprised to see it again so soon -- darn you Medium flexible URLs!

Usually you are supposed to add a year to older articles :)

Curious if you looked into other mail server options? I mean Postfix (not Postgres) easily handles the load of a single user, but it is still rather hard to configure and modify.

I recently started to work with Haraka and even thought its ment for high traffic use cases i wont ever look back to Postfix (not Postgres).

s/Postgres/Postfix/ ??

In any case you should ask the author, as they are currently active on another discussion where they linked their article in a comment: https://news.ycombinator.com/item?id=16238501#16238845

After dyndns.org decided to remove the free service, I was so pissed that I had to update all my devices including git checkouts etc.

So I decided not to go with any free providers anymore and get my own domain instead. So far no regret.

j_s · 8 years ago

For anyone willing to take the risk, another 3rd party service currently free was promoted on HN 6 months ago:

>opie34: A friend and I put together a free dynamic DNS service [1] offering cool custom domains aimed at the Raspberry Pi community (and similar hardware hackers.) It's not strictly a hardware project, but it's a crucial building block for any network-enabled Raspberry Pi project, and we'd love your feedback.

Wow, I didn't know there was such a cool hobby out there waiting for me. I know nothing about modern radio scanning but I'm suddenly fascinated to learn.

Things that aren't in the guidelines:

HN asks you not to treat the DOWNVOTE button as a DISAGREE

Things that are in the guidelines:

Please don't use uppercase for emphasis. If you want to emphasize a word or phrase, put asterisks around it and it will get italicized.*

Please don't comment about the voting on comments. It never does any good, and it makes boring reading.

Unfortunately downvote to disagree has been officially endorsed as inevitable. https://news.ycombinator.com/item?id=12330029#12330373

I wish there was even the tiniest bit of public accountability! Even user profile totals of upvotes, downvotes, comments, and flags would be a usable signal. Maybe one of the perks of being a YC company is seeing which accounts downvoted yours... ;)

I actually tested this theory recently; when I went to Machu Picchu, I took several pictures with my wife in them, and absolutely zero pics of the scenery or the monument. When I got home, I inserted some random high-res professional pics from recognizable vantage points into an album and called it a day. I don't feel shortchanged.

Although I'm somewhat glad for the tourist "gotta take my own shitty photo" attitude, because I saw a really nifty research project once that took thousands of tourist photos (of the Trevi Fountain IIRC) and combined them to generate a high-res 3d image without any people in it. That was pretty cool.

If I could change anything about my Machu Picchu experience, though, it would have been to find some way to shut up that blathering loudmouth moron in front of me who barely paused for breath for the entire duration of the morning hike to the nearby summit. Jesus christ lady, I couldn't hear a single nature sound, and I did NOT need to know about what a slut your cousin is.

My perspective grows stronger every time someone close to me dies: the true value in photos is the faces. As a tech person, that is where I try to maximize my pixel budget.

I actually prefer candid home video infinitely more -- most pictures on social networks are as authentic as pornography stills.
