Now and then, 14 years after I am visiting SF again!

Fly to Oakland for “Oakland”

@tianyigao.net and I just found clouds like AWS, GCP, Digital Ocean and Oracle pass packets with a non TCP/UDP number in the network header in their private network. This is not unsurprising given the network virtualization with middlebox features and good to see unosssified cloud networks.

Sunset walk around Belltown

day4 - random stuff from Daiso Redmond, went to BoA again to unfreeze the account day5 - meet friend near NSDI, went to RePC for old PCs, then Chinatown Day6 - work from home + lunch at HMart deli

My flat is between Bellevue and Redmond with a light rail station right downstairs. Funny thing is, it's easier to shop in Downtown Redmond than in Downtown Bellevue, because the Redmond station drops you right in the middle of Redmond, while the Bellevue one is kinda the side of the real downtown.

1st day - landed at 12 PM, moved in, opened Comcast (Xfinity) broadband, ate ramen nearby 2nd day - opened BoA account, went to a normal supermarket, a Korean supermarket, and a Chinese supermarket, ate a Chinese box meal, and a Chinese crepe 3rd day - assembled the bed from IKEA delivery

Help patching Datatracker during the code sprint was a huge joy! #ietf

IETF-125 Day1! #ietf

Prism (NSDI'21) was great to bypass L7 proxy with TCP connection migration, but hard to deploy as it needs a programmable switch. XO (NSDI'26) removes this barrier and is applicable to real apps, nginx and Ceph! micchie.net/files/xo-nsd...

I'll be joining @cloudflare.social as an intern this autumn in their London office! #cloudflare

Good day with an offer at dream company!

Applying Global Talent visa via Tech Nation is about get the pieces I left at river of time write up together.

Grateful for the recognition of SMT! Deep appreciation to @michioh.bsky.social for being the best supervisor ever, who helped make all this possible. SMT is an encrypted, message-based transport protocol. Details in our IEEE S&P'26 paper (micchie.net/files/smt-oa...).

2025 was a game-changer year for me, and my PhD has never felt this close. I visited so many places, reconnected with old friends, met amazing new friends across the world, got my first ever publications and citations. And I am already super excited for 2026! 🚀☕️🧑‍💻

A random magnet I bought at airpot in Portugal in a hurry, I asked the checkout lady what it means but I didn’t hear clearly. Today I am organizing my backpack and asked ChatGPT what that means. ChatGPT says it means “No bad thing lasts forever, and no good thing lasts without end.”

AWS down -> Zoom down -> Interview rescheduled, what a dramatic day....

E-Ink way to hack Edinburgh rainy and bus life.

I really enjoy the Cosener's conference even if I look a bit stressed at the time. I'm very happy with the community we have built here.

Happy to present at Coseners’25 (The 37th Multi-Service Networks workshop)! #coseners25

Got my work on encrypted datacenter transport accepted to APNet 2025! My first ever acceptance — a huge personal milestone. Deep thanks to my co-authors, especially my amazing supervisor @michioh.bsky.social, and my family for their support. Keep rolling! Preprint: arxiv.org/abs/2406.15686

Great honour to present my work at the Ninth Annual UK System Research Challenges Workshop!

Rebuttal night.
