I finished my last playthrough just before that patch dropped and have been curious to hear how it impacts that aspect of the game--best of luck with Project Exodus, they're next on my to-play list!

So the amplifiers used in subsea cables are called repeaters, which is a bit of a misnomer as they don't regenerate the signal, but what they do (besides power monitoring as these systems are far more sensitive than terrestrial) is match the total output power along the cable at regular intervals and along each individual fiber pair (as that can vary from pair to pair depending on potential use of different modulation schemes/transmission modes to support different client types), which allows for very minimal noise gain due to tighter component tolerance and better power monitoring than what is used in standard EDFAs terrestrially.
Additionally, relative to the signal to noise ratio, what is often done for subsea is that for a coherent transponder that might be capable of running at 1.6Tbps, it will be tuned down to maybe 1.4T or 1.3T to allow FEC to better overcome the total noise on the system. This is done in terrestrial applications too for long haul but is extremely prevalent for long subsea reaches.
Raman amplification is only typically used on short subsea links that are closer to terrestrial deployments than the subsea links I'm talking about.

Don't get me wrong, it's silly, but it shows a lack of attention to detail on the subject (one of the top comments on the embedded video debunks this immediately)--one which is genuinely fascinating given how little many people know about just how information is physically exchanged around the world. It's a dumb thing to get worked up over, I'll concede, but if the author is going to educate people on the matter they could at least fact check this bizarre claim. Cables are armored for a myriad of reasons outside of shark bites. The rest of the piece is interesting enough, and I highly recommend folks look into the coherent optical systems that transmit data over these cables (and all long haul terrestrial cables) if they're more curious about how the optical layer of the world's networks really function.

Comment on Alabama's Nick Saban retiring after seven national titles, most in major college football history in ~sports.american_football

The amount of new construction that occurred before I got to campus, while I was there for my degrees, and after I left, cannot be overstated. Chancellor Whit, a former chancellor of the school and one of the folks in charge when Saban was brought in gave a talk to my graduate school cohort and estimated the financial impact of this one man's hiring to have had a billion+ dollar impact on the school and surrounding community.
It's hard to believe that a person I've never even met (though I did get to stand next to him by merit of being in the marching band, which was cool) has had such an outsized but traceable impact on my life and the lives of so many others.
+1 for Traefik! My environment is predominantly Docker containers with a few VMs and baremetal hosts, and Traefik handles it all with ease. The ability to use labels on containers to define the parameters to Traefik is so nice, it's the best of SWAG (or whatever it used to be called before they got told to change it) but requires none of the complexity if you don't want it. If you put everything behind something like Authelia, you can easily define that in your entry points in Traefik and have reverse proxy enabled in as little as one traefik.enable label. Or you can go wild and manually tweak every little service like you'd expect with all the conf files SWAG gives you (assuming that's still how it works, I've been on Traefik for like five years now)
