Proud to announce that I’m interning at Apple this summer on the UIKit team!!

@astrange_e @khanhduytran0 Mine has to be DDS2

[fileintegrity @fileintegrity]

@astrange_e @khanhduytran0 Which ones your favorite?

[MVB @astrange_e]

That was truly a real Shin Megami Tensei game like Nocturne or Digital Devil Saga

[fileintegrity @fileintegrity]

@astrange_e @khanhduytran0 Do you know what Camera does now to get fast startup time? Or just nothing?

[fileintegrity @fileintegrity]

@astrange_e @khanhduytran0 Wait where is this

[fileintegrity @fileintegrity]

@astrange_e I hope my only option isn’t to wait for IDA to go through a release kernelcache so I can look for a symbol or two

[fileintegrity @fileintegrity]

@astrange_e Interesting, does XNU not compile with CONFIG_SECLUDED_MEMORY anymore?

[fileintegrity @fileintegrity]

@AhnafAMahmud No that’s just it being open but not showing it’s UI till you get your finger off the icon

[fileintegrity @fileintegrity]

Fun optimization: when you open an app on an iPhone, the OS has a hardcoded check for if it’s the camera app, and if so, grants it its own special memory pool (“secluded memory”) for faster start up times: https://t.co/T4lKXnLbRp

@trynothingy I’ve personally had a few instances where I wanted to take a photo of something fast enough before it would’ve went away, and the Camera app being able to open fast enough was my number 1 priority

[fileintegrity @fileintegrity]

@trynothingy Yeah, I ^imagine^ that Camera and cameracapture daemon are memory beasts, and consumers probably prioritize taking a photo in time than having YouTube stay on the same video you were watching

[fileintegrity @fileintegrity]

@DylangerDaly @bastiengares I assume Camera needs to allocate a bunch of stuff so this is why they do this?

[fileintegrity @fileintegrity]

@DylangerDaly @bastiengares From what I understand after reading vm_page.c is that secluded memory pages are given priority over normal memory pages (as they have their own queue)

[fileintegrity @fileintegrity]

@kylemacomber Does this mean there were no spring animations before in-process animations arrived?

[fileintegrity @fileintegrity]

@SebJVidal Rockstar

[fileintegrity @fileintegrity]

@kylemacomber I couldn’t think of a more fun project to work on

[fileintegrity @fileintegrity]

@SoVeryCuul @SebJVidal @samhenrigold Solid but oof some UI glitches really stand out

[fileintegrity @fileintegrity]

@SoVeryCuul @SebJVidal @samhenrigold On it now!

[fileintegrity @fileintegrity]

@luciascarlet @SebJVidal @samhenrigold You should sell it

[fileintegrity @fileintegrity]

@SebJVidal @samhenrigold I wanna try 27.0 RC but so scared of the risk
