Another work as a co-author got accepted to USENIX FAST 2023, this time it's Android (UFS)!
I'm grateful for the team and the opportunity allowing me to work on something that's my passion.
usenix.org/conference/fas…
I believe it'll be published sometime in Feb, 2023.

@Nimueh6 Then use adb. I don't understand what this has to do anything with unlocked bootloader.
English

@arter97 I did read it last night already, and my point stands.
If this was about "protecting" anybody then goolag would exclude bootloader unlocked devices from those shenanigans. "Tech-un-savy falls-for-scams" and "unlocked bootloader" are 2 very different groups of people.

Reasonable.

📢 Important update on sideloading on Android It’s of course here to stay. The team’s been listening carefully to feedback from power users who want a way (apart from ADB) to install apps that don’t go through developer verification. Today, we have more details on the advanced flow that gives you this option. Read the post👇 for more info goo.gle/advance-flow

@arter97 The hell it is! More nannying and trying to get people to stop modding their devices, to stop devs from leaving the play store! It has nothing to do with "protecting" anybody, it's just another step towards turning Android into crApple! 😡

NP3a ships 6.1 kernel.
This is my first time trying out a fully ported kernel from a higher branch and it's surprisingly very usable.
Heavy lifting was done by Qualcomm but still this is very impressive. Hats off to @ZVNexus

A pushup competition with @PGelsinger.
I rarely workout and need to lose weight.
Pat does calesthetics.
I lost by a lot 🙃😁
Full 60 minute interview coming live next week or two.

"We're killing it bc not enough users are opting-in to it" has to be the dumbest fucking excuse ever to kill end-to-end encryption.

@MishaalRahman In layman's term, the kernel keeps punching the compiler in the face until it makes it go faster.
English

Dev Team: "We're making your Android device feel faster and last longer."
Me: "How?"
Dev Team: "Oh, we're leveraging a technique called AutoFDO to rebuild the kernel using profiles that direct the compiler to make smarter optimization decisions about instruction execution paths."
Me: "I barely understand what you just said, but that's dope."

@arter97 Smart Switch is an app which you install on Phone and PC and it works
English

@VedantKalore No shit, sherlock. I mean what mode will the phone be on?
English

@techkeyz333 What if you need to recover from an unbootable state?
English

@arter97 You can still, ignore that retard. One of the methods already known is by entering maintenance mode.

@arter97 Can't wait for this to come to other brands as well

BREAKING: Alibaba tested 18 AI coding agents on 100 real codebases, spanning 233 days each. they failed spectacularly.
turns out passing tests once is easy. maintaining code for 8 months without breaking everything is where AI completely collapses.
SWE-CI is the first benchmark that measures long-term code maintenance instead of one-shot bug fixes. each task tracks 71 consecutive commits of real evolution.
75% of models break previously working code during maintenance. only Claude Opus 4.5 and 4.6 stay above 50% zero-regression rate. every other model accumulates technical debt that compounds with every single iteration.
here's the brutal part:
- HumanEval and SWE-bench measure "does it work right now"
- SWE-CI measures "does it still work after 8 months of changes"
agents optimized for snapshot testing write brittle code that passes tests today but becomes completely unmaintainable tomorrow.
they built EvoScore to weight later iterations heavier than early ones. agents that sacrifice code quality for quick wins get punished when the consequences compound.
the AI coding narrative just got more honest.
most models can write code. almost none can maintain it.

40% of CPU time on Android happens in the kernel. 🧠 We thought it was time to optimize that → goo.gle/3NvpEhV
By applying AutoFDO to the Android kernel, we can move beyond a reliance on static code hints and compiler heuristics. The result is a snappier interface and 2.1% faster boot times.

We in the level1techs community have launched a sensor telemetry package on Linux, in rust, that hopefully doesn't suck.

@arter97 why is a bootloader unlocked being leaked? it's OUR RIGHT.
