You can enforce certificate pinning in your own native app. You can even go as far as not trusting the hookable (on a JBen device) system libraries and link in your own OpenSSL or something similar.

I’d love to see your updates. My friend was commenting a while ago about how Milkdrop’s old DX version limited length of shaders he could write.

So now the page needs to checksum itself once loaded to detect tampering.

I purchased a G5 tower for cheap, on a whim, from my local university surplus store. There was a strange sign that said "may leak". I was really confused as to why they were talking about memory leaks W.R.T. hardware. Only once I

Yup, this was done in this years USENIX with AMD microcode. See the exploits that check for magic register values at [0] and the paper at [1]. [0]: https://github.com/RUB-SysSec/Microcode/tree/master/upda

XNU has an equivalent to vDSO: the commpage. It is also used for time.

Indeed, SEP is a separate ARMv7 core apart from the application processor. EL3 on the AP is used for KPP. [0] [0]: https://xerub.github.io/ios/kpp/2017/04/13/tick-tock.html

The problems that are solved by PTYs finally "clicked" for me when I read their example of the problematic fseek/flushing. I hadn't seen such a cogent expiation until now.

You might be able to use libhoudini for ARM emulation on x86.

I would imagine that with enough engineering effort, a cross-architecture "porting" of IR would be feasible. I doubt Apple will bother to do that when they can just force developers to rebuild and republish lest they get left out

App thinning is orthogonal to ENABLE_BITCODE. The App Store could have been thinning app binaries years ago (literally just `lipo -thin`). Apple likely wanted ENABLE_BITCODE for better app store verification and perhaps architecture re-ta

I asked Gor if you can use LLVM's coroutines without a runtime. He answered in the affirmative (subject to some constraints), which I take as evidence, along with his presentations, that these optimizations do indeed take place. https

I'm not sure why the article laments CableCard. It allows me to watch most of my cable channels using my HD HomeRun ethernet CableCard tuner using just VLC. The premium (think HBO) channels are protected by DTCP DRM but lets just say t

It VHDL as implemented at the time was broken, at least as of 2010. [0] VHDL 2008 support would have definitely had a positive impact on the VHDL source code (making it smaller and more comprehensible). There were so many 2008 features I wi

I was able to avoid X-ray exposure to all of my film (some of which was ISO 1600 that I was pushing to 3200) during a trip to Washington D.C. not long after the 9/11 attacks. At that time, all of the security checkpoints at the airport

I enjoy B&W film photography as a hobby. I do not think I would enjoy any sort of film cinematography, due to the larger scale. A 24 frame roll of photo film is one thing but a reel of cinema film is another!

Because the feeder holds a single meal and is designed for access control (multiple pets) and not really automatic/timed feeding. A feeder with a sort of food hopper isn't too useful to me since I alternate dry/wet food for b

The feeder only contains room for a day's worth of food, it doesn't have a "hopper" and isn't designed for unattended use. It's (unhacked) purpose is mostly for multiple pet households to prevent food theft or

Very good points about monitoring your cat's inputs and outputs. My cat develops urinary tract issues about once a year and you notice the reduced appetite and litter box use. I have a Litter Robot so I do make sure to check it at leas
