Ask HN: Which mailing lists would you recommend to subscribe to?

The classic metzdowd cryptography list is generally good reading: https://www.metzdowd.com/mailman/listinfo/cryptography

Another good fly-on-the-wall place to see what's going on in a specific tech niche is the dns-oarc operations list: https://lists.dns-oarc.net/mailman/listinfo/dns-operations

Are you asking about newsletters or mailing lists? It seems that most people are posting their favorite newsletters.

Newsletter: 1 to many

Mailing list: many to many

I'm quite enjoying 8Bit News, which deliver articles about... 8Bit retro computing: https://8bitnews.io

I was asking about mailing lists, but even so, people who are posting interesting newsletters are also very welcome.

BTW, thank you everyone who posted (or is going to post) an answer. There are many great suggestions!

I use Feedly / NetNewsFire for feeds, rather than newsletters, but in reality they're the same, just different consumption methods. Just interesting to see NNW was in HN recently. These are the most interesting things I keep in Feedly.

acoup.blog - A Collection of Unmitigated Pedantry - frequently linked to HN already. He's a great history writer, covering everything from Roman logistics, to analysis of current games and movies - eg. LotR battles.

https://www.youtube.com/channel/UC364qOwWXAzgRruHhhFMhVg - Croker vs Rover. A New Zealand guy restoring a 70s Land Rover. It's a Youtube channel, but both hilarious and informative. Infrequent too, so easy to cruise through at leisure.

Atlas Obscura - https://www.atlasobscura.com/ - interesting history/geography mix.

https://www.numberphile.com/ - Mathy easy-access but complex topics - mostly videos on Youtube. Very accessible, but interesting for a mostly non-math person to see real math at work.

https://waynehale.wordpress.com/ - Wayne Hale - NASA flight controller. Interesting views and analysis of current space / incident management topics vs how it was done for the shuttle, along with some other commentary. Infrequent and interesting.

https://computer.rip/ - Deeply geekly telco / 50s-70s computer history with some cold-war fun. Pretty in-depth, and a fun read.

https://www.cringely.com/ - Cringley - weekly-monthly tech posts on bigger tech strategy with an Appleish focus. He's been around SV for years. Was early at Apple then made documentaries, was a journalist, and blogged for years,

https://mondaynote.com/ - Jean-Louie Gassee's monday musings on tech, mostly Apple. Originally Apple, then founded Be, then chairman of Palm. Been around the block in tech.

https://www.techdirt.com/ - legal analysis in a similar style to Matt Levine (who's also a must-read for finance). Funny and informative.

https://usesthis.com/ - The setup - weekly post on someone's tech setup and tools they use. "Uses This is a collection of nerdy interviews asking people from all walks of life what they use to get the job done."

Matt Levine - Bloomberg Money Stuff - already mentioned, but here as a second vote for him. Hilarious financial industry commentary.

https://monitoring.love/ - weekly tech newsletter with a focus on Monitoring/SRE type topics. Also a good Slack server if you like SRE/Monitoring stuff

BOFH - https://www.theregister.com/Author/Simon-Travaglia - the original author's currently (and for the last 20 years or so), been on The Register. Not as good as it once was, but funny, and worth the weeklyish read.
