@Alabbar94 @miniapeur 0/0 is not an indeterminate form??? since when

@JayDwivedi_ Trust math in design.
The left version feels more balanced because the surface areas are closer.
Two circles (d = 100): ≈ 15,708
Pill (W = 92): ≈ 16,584 → difference ≈ 876
Pill (W = 100): ≈ 17,854 → difference ≈ 2,146

Remember the “leopard spots” rock Perseverance sampled last year?
After a year of scientific scrutiny, the rock remains the mission's best candidate for containing signs of ancient microbial life processes. More on this peer-reviewed finding: go.nasa.gov/4nmZuKm

@halvarflake MTE has been in production since October 2023 via GrapheneOS on the Pixel 8.
x.com/GrapheneOS/sta…
Google's Android 16 Advanced Protection Mode is not the first production deployment and is far more limited than what we've provided for 2 years and are working on expanding.
GrapheneOS@GrapheneOS
Pixels have provided hardware memory tagging (MTE) support since the Pixel 8. GrapheneOS deployed it in production around a month after the launch of the Pixel 8 and we use it for the kernel and nearly the entire base OS. We use it for some third party apps and users can opt-in to using it for all. There have been multiple revisions of ARM MTE. FEAT_MTE4 (Enhanced Memory Tagging Extension) is the 4th generation of ARM MTE improvements, not the beginning of it. The baseline feature was already a game changer for defending devices. The improvements will make their way to devices providing it. Being able to leak data via side channels is a known issue with modern CPUs with many rounds of issues being discovered and addressed. ARM has been working on fully resolving it for MTE itself. Apple CPUs have had much more severe issues with side channels than Cortex, so it's a strange jab by them. Unlike iPhone users, GrapheneOS users have been well protected by attacks from Cellebrite and other exploit development companies. discuss.grapheneos.org/d/14344-celleb… Apple talks a big game but consistently fails to protect their users against broadly deployed exploits used at a large scale. ARM shipped MTE support multiple years before Apple in their Cortex cores. Yes, it was discovered to have a side channel usable by local attackers. This doesn't ruin it. MTE only has 4 bit tags which is a bigger weakness than the side channel. MTE still paves the way for stronger future features. Apple has far more severe side channels in their hardware which leak user data. It's strange to portray leaking tags as a severe issue ruining a feature when they've consistently downplayed the impact of endless side channels vulnerabilities directly leaking sensitive user data on iPhones and Macs.

@dcominottim @yifanlu Many uses and many cares. only reason it exists is because people care, not because of shareholder interests. GrapheneOS has better security than Apple.
@GrapheneOS How many active user we have, rough estimate based on downloads?
English
@slashtabDev @yifanlu Nobody cares and nobody uses it.

> Google took a great first step last year when they offered MTE to those who opt in to their program for at-risk users. But even for users who turn it on, the effectiveness of MTE on Android is limited

@haveibeenpwned seems like @plex got hacked
They have sent email reporting the incident.

@Avamander @PiereChangstein @rajxnull MTE provides 4 bit tags providing a relatively high probability of detecting exploits. It's not memory safety. It's the first step towards strong memory tagging. There's around a 1/15 chance to bypass it for each part of an exploit it impacts without having any side channels.

@Avamander @PiereChangstein @rajxnull Apple and Google pretend as if they have omniscience and are aware of when their devices get exploited. They do not and they are not aware of the vast majority of exploits. The claims both companies make about rare exploits are outrageously false marketing disproven by evidence.

@Avamander @PiereChangstein @rajxnull It's not as if Apple's integration of features like PAC and MTE is going to be perfect with no caveats.
Apple's claim about lack of widespread exploits for iOS is provably false. Leaked documentation and data shows otherwise. Apple devices are widely exploited in the wild.
