As the operator of a soup kitchen, I don’t see why I should be expected to fix health code violations people report. After all, we are run almost entirely by volunteers

GPT-5 has a much higher opinion of my hardware skills than is warranted. I mentioned my wife’s laptop died and it’s trying to sell me on the notion that tracing a bad MOSFET and replacing it with a hot air rework station is the easy, practical option

I don't understand why companies get so upset when I extend them a short-term loan with highly favorable repayment terms*?? Do they want me to charge interest??? * (Forget to submit reimbursements for months)

CCS has come to a close, and so has the first-ever SURE Workshop. We want to thank the authors, the PC, @moyix, our panel, and CCS for making SURE a success. We felt the support for this research area (the room was packed out for more than half the day). See you all next year!

The Efficient Altruism Hypothesis states that if you see a child drowning in a pond, you should keep on walking; if they were really drowning someone would have already saved them.

We just had our first talk of the day, our spectacular keynote from @moyix. He explored reverse engineering and discussed how we still have a long way to go in making questions about programs accessible to non-technical people. We'll be live-tweeting talks as they happen!
