Hyperscalers Lead The Way To The Future With SmartNICs by The Next Platform (2019)

Associated article: www.nextplatform.com/2019/10/31/hypercalers-lead-the-way-to-the-future-with-smartnics/ mentions that:
Google is widely believed to be working on its own design.
This section explains a tutorial on how to allow external computers to access a computer in your network.
For example, this could for example be used to allow you to access SSH or a web server running on a computer at your home from your laptop when you are outside of your home.
What you need to do seems to be:From there on, you just need to find your public IP and use that, e.g. you could test accessing a test server from your cell phone cellular network after turning Wifi off for the cell phone.
- NAT Forwarding: allows you to select which external port you want to forward to which internal IP + port
- Network > LAN Settings > Address reservation > and reserve the IP above to the MAC of your computer
Ciro Santilli tested this on his TP-Link Archer VR2800 router Virgin Media Hub 3.0 Wifi setup and it just worked. Virgin Media doesn't seem to pose any strict restrictions to this.
A next good step if you are going to have a workhorse computer without much personal logins of value is to setup "group isolation" so that if that computer ever gets compromised, hackers won't be able to infiltrate the rest of the network. But TODO: couldn't find the setting on the TP-Link Archer VR2800 even though the manual says it should be there. Oh well.
- "Operation mode" > "Wireless router mode" (was "DSL Modem/Router mode" by default).
- "Network" > "Internet" > "Add" > "Internet Connection Type" > "Dynamic IP" > "Save"
Custom configs we had, not sure if mandatory:
- Dynamic DHPC mode
- Unicast DHCP
Wait for TP link to fully reboot.
Connect port 4 of tp link (marked WAN/LAn) to port 1 of VM Hub (unmarked, but it is magic, has to be port 1).
Finally, AFTER everything else is setup, turn on the Hub and wait for a few minutes. It ONY WORKS if you turn it on after everything is setup.
Outcome:
- hub light turns purple: www.reddit.com/r/VirginMedia/comments/c703t6/purple_light_on_the_box/
- Archer WAN light turns on white. Not red. Red means error
- you have Wifi. Notably, the 5G Wifi is way way faster and reaches the WAN limit of 256 Mbps.
- Ethernet does not work anymore on either Hub nor Archer, Wifi only. But it doesn't matter because the 5G Wifi already reaches the speed limit.

A switch is a box with a bunch of Ethernet wires coming into it:Except that it doesn't have to be Ethernet, e.g. it would also be a Wi-Fi.
+--------------------+
| +-+ +-+ +-+ +-+ |
| |1| |2| |3| |4| |
| +-+ +-+ +-+ +-+ |
+--------------------+
What the switch does is:
After the destination is found, a confirmation is somehow sent back to the switch, which then learns which wire to send each MAC address to.
A switch is a bit like a router but it is a bit dumber/operates at a lower level: it basically operates only on MAC addresses, not on IP addresses.
The Internet service provider boxes most people have at home combines a switch for the local network and a router for the ISP communication.

Nothing phenomenally new on the early days to add on top of Video "Nerds 2.0.1 excerpt about Cisco (1998)", but a few new good points:
- Cisco at one point became the largest company by market capitalization. This wore off a bit as of 2020.They used this overvalued stock in part to buy many other (often also overvalued) up and coming companies. This acquisition spree strategy was apparently not the norm at the time. rohitnair.wordpress.com/2011/12/13/cisco-history-cisco-systems-history-and-trivia-brand-history-and-trivia/ mentions they have bought more than 140 companies since, and that they call this strategy "Build, Buy And Partner"
- a big part of what Cisco did was to allow cheap local communication in-campus. At that time, the ARPANET was already up and running, but their "routers", called Interface Message Processors were very expensive at about $100,000, and to send data across the campus you had to go through them, which meant expensive bandwidth. The routers sometimes failed, and the fallback was to send students around with disks: "sneakernet". They needed new local protocols and hardware to efficiently connect different campus networks.

- Cisco was a pioneer in having an Internet support forum. Customers could also help one another. This was fundamental in scaling support, as they grew so fast it would be impossible to hire a support team large enough without the help of the forum.
- Cisco gave out source code to some customers who would then implement protocols they cared about, and Cisco would then merge it back

She's kind of lying on top of the horse's back, and you can't see much, just some tastefully light erotica. It's not like she's fucking the horse or anything.
As per stackoverflow.com/a/52351480/895245 our standard test setup is:
while true; do
resp=$"$(date): hello\n"
len="$(printf '%s' "$resp" | wc -c)"
printf "HTTP/1.1 200 OK\r\nContent-Length: $len\r\n\r\n${resp}\n" | nc -Nl 8000

It runs one instance of the Linux kernel and has one IP address. Each node is therefore a complete computer. As such is must also contain RAM memory, disk storage and a network interface controller.
E.g.:
HP Blade Server by Brian Kirsch (2013)
Source. Featuring an HP DL380 blade server, presumably an older model of this series: buy.hpe.com/uk/en/servers/proliant-dl-servers/proliant-dl300-servers/proliant-dl380-server/hpe-proliant-dl380-gen10-server/p/1010026818.
In the video we can see that it contains RAM, disk storage, we are told about two CPUs, and networking interfaces, so it is a complete computer on its own. He also explains that unlike typical rack servers, each blade unit does not have its own coolers and power supply related hardware, which goes instead on the chassis.
