Hi, I'm the network "engineer". You may know me from ticket replies such as "it's DNS", "that is not our network", and "the packet loss is only showing on intermediate hops in the traceroute provided because ICMP hits the control plane, unlike your application traffic"
Hi, I'm a creative AI user. You may know me from my greatest hits "No, it's not self-aware," "Actually, I'm the creative one, not the algorithm," "Stop generating birds with no feet and two heads," and "Okay yes technically I DID ask for that but that's not what I meant"
in my 20s: “telecom engineer”
in my 30s: “everything after your wifi router”
in my upcoming 40s: “I’m really into caring for bunnies and also becoming a honey sommelier in Italy”
When people ask me what I do:
In my 20s: "As a senior network engineer, I build complex networks and systems to connect globally distributed workloads"
In my 30s: "I'm in IT"
Well, it finally happened: I'm being paid expressly (by direct customer request!) to generate an IPv6 addressing plan for production deployment this year.
2020 is truly wild

cool. it’s still not thinking. it’s an almost unappreciatively large amount of multiplication that gives probabilities. you might enjoy the cadre of folks breaking the model in fun ways. like mentioning that reddit user than “won” the counting subreddit
you absolutely do not need or want “AI” for this. you can validate and even verify ACLs using deterministic math not spicy autocomplete.
💯 snakeoil. pls fight me!

they understandably could not conceive a branch being co-opted so thoroughly. only so many fail safes you can build in. at some point, it's up to the governed...
network friends please tell software engineering friends that crawling the entire route table, especially on a router that carries "the full internet" is a very expensive proposition when done via...SNMP

I’m sorry a GPU accelerated what? terminal emulator?? is this a joke on old people like me??? is anyone stopping to like, think about this??????
what the hell does a GPU accelerate on a mf teletype emulator
help meeee
"Intel intends to open Tofino in the long term. As it is the case with general purpose CPUs, we believe that people should be able to learn about the architecture and interfaces, teach about them and write the code openly. This announcement is just the first step. Stay tuned!"
I really don't know what everyone is on about
Hollywood prop designers have solved the IPv4 number depletion like, decades ago at this point.
if IPv6 was truly superior (looked cooler) then, obviously, that's what Hollywood would have went with. but they didn't. they fixed IPv4

if engineers could sell, they would be. believe me. you know how many beautiful shits us engineers can design that only we can appreciate *without* sales? ‘bout all of it, really.
it bites but it is reality
“Rust achieves 98% of C’s throughput at the same worst-case latency of 22 μs (median 5μs) while at the same time guaranteeing memory safety in 87% of the source code. The other languages fare worse and should not be the first choice for building a packet processing system”
Marvell is demonstrating OFC this week the industry’s first 800 Gbps ZR/ZR+ pluggable module with probabilistic constellation shaping (PCS). With PCS enabled, the reach of a Marvell COLORZ 800 module at full bandwidth doubles from 500km to 1000km.
Expected capacity of Starship is about 150 tonne, so that means about 120 Gen2 Starlinks per launch. That means to deploy 30k sats you need 250 Starship launches. Expected on-orbit lifetime is same as Gen1: 5 to 7yrs.
Someone asked me what was behind all the doors in locomotives.
So I started opening all the doors and explaining it to them until they asked me to stop.
my partner, who just finished her manuscript for OReilly on data privacy, sent a GDPR to the ChatGPT folks and this…
…this could be the beginning of something beautiful 🙌🤓🥹

farts are universally funny. they transcend language and culture. people who don't find farts funny find farts unfunny not because farts are not funny; but for a whole bunch of other reasons unrelated to flatulence itself.
Friends don't let friends buy and provision 1GE peering ports.
Seriously. Don't do it. if the MRC on a 10GE port is too high, you don't need to be peering there at all.
Don’t sleep on BGP. It used to be in SP networks mainly. Then it spread to datacenters. Now it’s starting to gain traction in the campus as well. It’s also used in public cloud.
Ethernet and TCP/IP first, but don’t wait with BGP until you are at expert level.
"Beyond 100GbE, all packet sizes will arrive faster than main memory can accommodate, resulting packet drops due to the latency incurred by the memory hierarchy. We call these losses caused by the gap between cache and DRAM, Dark Packets"

in a lovely, unintentional turn of events I'm creating the demand I have long wanted to see:
I'm hiring (contract) P4 developers.
specifically with experience / understanding of eBPF & XDP as a target.
remote only. students/academic/researchers preferred!

any melon huskers wanna argue with me about five year phallic space junk vs 25 year or more, orders on orders of magnitude more bandwidth (literally), glass in the ground?
last time I saw all the IX operators talk about a traffic surge in unison like this was the day MJ died.
does fortnite literally yolo the client upgrades? everything all at once everywhere? 😳
triply so for IP addresses in examples and documentation. stop using 3.3.3.3 and 4.4.4.4. frankly, despite how good your content might be -- I silently judge you. negatively.
RFC3849 & RFC5737
read 'em. use 'em.
Another pedantic reminder that you should use instead of (or anything that you think it's dummy) in your examples. is standardized for this purpose, is proprietary.

completely ignoring even the most basic of best current practices (like setting a sane max-prefix on customer facing BGP sessions).
back in my day there was absolutely no way to lose 1.5TB of storage.
misplacing an M.2 form factor drive is simply too easy. I declare this a design flaw
GTT adds PoP, new logo and exits Chapter 11 cases. The managed service provider is launching a new point of presence in Portland and has emerged from nearly $3 billion in debt plus Chapter 11 cases.
