A round sticker that says I voted! The letter v is a check mark, even though to vote you fill in round circles like on an SAT test rather than drawing a check mark. The sticker is half red and half blue; the red half features an abridged version of the New York City skyline in negative space. I am trying not to let the order of the buildings get to me, but the Statue of Liberty being placed closer to the Empire State Building than One World Trade is rustling my jimmies pretty hard. There are also stars in the blue half just in case it wasn’t clear that you are in the United States.
A screenshot of my title slide. It says "A Love Letter to Isolation" with my name, social handles, and Cloud Native Wasm Day 2023. The background looks like a white, textured piece of paper with a kiss mark in red lipstick. You can just feel the presentation will be a steamy nerd fest.
a photo of me standing against a brick wall wearing a costume based on the character Ken in the Barbie movie. A lightning bandana peeks out from under my beach blonde hair; Ken’s job is beach, after all. I am wearing a black fringed leather vest with lightning pants and white sneakers. To really make this outfit cool, I am wearing a fanny pack with Ken on it in Metallica font. I am sticking my tongue out because I feel so Kenough and also displaying peace fingers because that is part of the bisexual licensing agreement. I am posed near my chrysanthemums in shades of joyful yellow, content fuschia, and cozy umber. There is an orange pumpkin peaking out from behind the mums. It's very festive. Oh, I also have abs. Like, a lot of them. It's super impressive.
A photo of me standing in front of a Barbie display at a movie theater while holding my book, Security Chaos Engineering Sustaining Resilience in Software and Systems. I am dressed in Barbie style. I have my hair in a fluffy ponytail-like style and am wearing pale pink heart-shaped sunglasses with pink lipstick. My outfit is a fuzzy pastel pink cropped top underneath a butter yellow tweed blazer, with hot pink shorts and pink patent leather platform loafers. I am posed like a Barbie, as if my hand cannot be moved fluidly because I am made of plastic. I am smiling because I am so proud of my achievement in publishing the book.
A screenshot of an anti-bot challenge. The instructions read Use the arrows to rotate the animal to face in the direction of the hand. Below it is a picture of a hand next to a picture of an animal you can rotate. The hand has two fingers pointing.
A photo of a cat sniffing a ruler. The ruler is hot pink with holographic Lisa Frank animals on it. The cat is black and white with jade green eyes and a preposterously fluffy coat.
A pic of me in a red shiny catsuit holding the cover of my book. My hair is in space buns and it’s all Y2K as fuck. I’m in a park in early spring with a blue sky.
A picture of me holding my tiny book on a tropical beach. I am wearing a black bikini and denim shorts with a blonde ponytail. My skin is incredibly pale since I’m a vampire.
A photo of me in the Rocky Mountains licking a book. I’m specifically licking the Security Chaos Engineering report i published in 2020. I’m wearing all black athletic gear with a blonde pony tail — and my tongue is very long. Longer than you’re imagining. Truly. The vibe I radiate is “yes, thirsty mortal, you can bask in my brilliance.”

This is used by the core dump code to decide which regset to dump. The core dump code writes out the resulting .e_machine and the corresponding regsets. This is suboptimal if the task is messing around with its CS.L field, but at worst the core dump will end up missing some information. Unfortunately, it is also used by the broken PTRACE_GETREGSET and PTRACE_SETREGSET APIs. These APIs look at the .regsets field but have no way to make sure that the e_machine they use matches the caller's expectations. The result is that the data format returned by PTRACE_GETREGSET depends on the returned CS field (and even the offset of the returned CS field depends on its value!) and the data format accepted by PTRACE_SETREGSET is determined by the old CS value. The upshot is that it is basically impossible to use these APIs correctly. The best way to fix it in the long run would probably be to add new improved ptrace() APIs to read and write registers reliably, possibly by allowing userspace to selec
