A gnu screen session hosting an irc client so I can stay connected.

I work on game servers. I can only dream of such an IPC, but it doesn’t stop me trying, heh.

I keep a Starlink subscription as my WAN2, after someone started a fire in a nearby fiber cabinet and managed to knock out Frontier and Spectrum at once. It’s worth it to me as a bullet-proof WAN2, especially working from home.

Yamaha also made top-end archery gear for quite a while. Infamous for metric threads when nearly everything else used imperial.

My first job out of university was at IBM wrangling a prototype some research PHDs had written into a shipping product, and.. yeah, this tracks.

Related, to this day my Frontier connection black holes all my traffic a couple of hops inside their network if I do sustained line-rate UDP (WireGuard, for example) for more then three or four minutes. After some LinkedIn sleuthing I got in touch with their local NOC director who tells me it’s some piece of gear that hangs so bad he can’t remote into it and it stays down until the watchdog fires. Been that way for two years now.

As a games coder I was glad when the xbox 360 / ps3 era came to an end; getting big endian clients talking to little endian servers was an endless source of bugs.

New comment by ultrahax in "Increasing QUIC and UDP Throughput over Tailscale"

ultrahax — Tue, 21 Nov 2023 00:56:13 +0000

Tangentially, I've faced some interesting challenges getting a multi-gigabit Wireguard VPN operating through my 2Gb Frontier connection.

My UDM Pro seems to top out around ~800mbit per UDP stream - pegged at 100% CPU on a single core. Likely it can't keep up with the interrupt rate, given it's ksoftirqd pegging it. Replaced UDM Pro with a pfsense machine.

Then I started getting 100% packet loss on the edge of Frontier's network after a couple of minutes of sustained UDP near-line-rate throughput. In the end, after trying and failing to explain this to Frontier's tech support, I reached out to their engineering management on LinkedIn, and got put in touch with the local NOC director. Turns out to be some intermediate hop is rebooting after a few mins, and they're "in contact with the manufacturer". Haven't heard back in a few months.

tldr as >1Gb connections become more ubiquitous, other bottlenecks will become apparent!

Citibank did this to me. Venmo'd my architect for some work he was going on my house, kablammo, account closed, no notice. Was just lucky it was an account set up specifically for work on that house and not my that's-where-my-paycheck-goes account.

“Physics package” is usually a phrase meaning the explodey bits of a nuclear weapon, so that lines up.
