PSA: Following a sample of my latest teaching review: "Prof Crooks's accent is somewhat distracting. I think it's something to do with the rise in pitch at the end of a sentence". I will now be adopting a Texas drawl in honour of my UT PhD. Please bear with me as I perfect it over the next year.

The US Administration has indefinitely blocked *all* student visa applicants from getting a visa interview.

Worldwide, unconditional, no end date. All.

International students are crucial to the US university system, American innovation, and future US prosperity.
Rubio Reportedly Pauses New International Student Visa Interviews
More than 1.1 million international students were enrolled at U.S. colleges and universities in the 2023-2024 school year.

They’re basically just trying to kill off US higher education as an industry at this point. Even a delay will pose a critical decision for thousands of prospective students whose futures are now in the air.

It’s that time of the year again, when the air smells fresh, the flowers are blooming and systems researchers are in a windowless room because it’s the SOSP deadline! I wrote these hints on writing an SOSP paper some time ago but it’s still a great reference. irenezhang.net/blog/2021/06...

Very grateful to be part of the 2025 Sloan Research Fellow cohort.

Thank you my fantastic students and amazing colleagues who have made this possible!

Many of them will be graduating soon. Hire them!
🎉Congrats to the 126 early-career scientists who have been awarded a Sloan Research Fellowship this year! These exceptional scholars are drawn from 51 institutions across the US and Canada, and represent the next generation of groundbreaking researchers. sloan.org/fellowships/...

I wanted to go through the rest of the disaggregated OLTP papers in detail, as I'd missed a few, so I'm re-reading everything and incrementally filling in more papers on transactional.blog/notes-on/dis...

Recent additions are overviews for Aurora Serverless and PolarFS.

Continuing from yesterday's blog post, today I look at an interesting isolation edge-case from the literature: Fekete's Anomaly. How does it fit in to our theme of achieving performance, scalability, and reliability through reducing coordination? New blog post here: brooker.co.za/blog/2025/02...

I’m an NSF panel reviewer that was scheduled to meet today. Just got notice that all NSF panels were canceled today. I reviewed some innovative proposals in support of students. Devastating if these scholars don’t get to do this work. For the love of science & students I hope this is just a delay.💔

Female colleagues in CS: how often a year do you get mistaken for one of your male colleagues' secretary?

I'm already at one this year and it's not even Feb!

PS: you don't want me coordinating your calendar. I will accidentally double book you and schedule 7 am meetings.
January 13, 2025 at 5:23 PM
Dear Students, as University X require me to rate your artistitic ability, and University Y require me to rate your competency in a foreign language. I henceforth require all meetings to be conducted in French while dancing a cèilidh as a precondition to me writing a reference.

Thank you.

There is a special place in hell for schools that require you to rate applicants across 10 axes for recommendation letters and don't just let you upload the standard PDF.

I am disappointed to see that Brown no longer requires me to rate the artistic ability of the people I am recommending me for PhD admissions in CS. I was enjoying the mandatory tap dancing interview prior to agreeing to write them a letter.

One of the biggest difference between faculty life and student life is deadlines. Deadlines for students are more intense. Feels like all or nothing, all eggs in one project. But then you can relax. I find myself having to delay all *other* important things to Wednesday or Thursday, no rest allowed

Academic Twitter, a (very strong) Iranian student is telling me that he cannot afford the PhD application fee at Berkeley (155$, a month of his father's salary he says). Are there any solutions to request application fee waivers for international students in this situation?

Which schools allow it?

I guess nobody said submitting to Osdi would be easy.

But trying to reason through BFT proofs with a fever and one eye on the tsunami watch website, is just a little *too* hard.
