@esrtweet In default OpenWrt configuration, there is firewall rule preventing SSH access from the internet, additionaly dnsmasq prevents this issue. There are downstream projects like TurrisOS which choose OpenSSH, so they're affected.

It's a pity we can't ask Astra to fix Sol

[Rikiya Takehi @rikiyatakehi]

We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math.
It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training.

We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵

Software fails because of vibes.
Hardware fails because of (8.2 kHz) vibes.
Full-stack vibes.

[Zoe @zoecyber001]

You do not need an RF jammer or a cyber exploit to knock a drone out of the sky. In 2015, security researchers proved that playing an 8.2 kHz sound wave at an unprotected flight controller forces it to drop instantaneously.

This is an acoustic resonance attack, and it exploits a mechanical vulnerability in the micro-electro-mechanical systems (MEMS) inside consumer gyroscopes and hard drives.

1. The anatomy of a vibrating silicon spring

Inside a drone's flight controller sits an Inertial Measurement Unit (IMU). The core of that IMU is a MEMS gyroscope measuring less than four millimeters across.

Inside the chip, a microscopic silicon proof mass is suspended above a substrate by silicon micro-springs. The internal drive circuit vibrates this mass back and forth at a known drive frequency.

When the drone rotates along its pitch, roll, or yaw axis, the Coriolis force deflects the proof mass toward fixed capacitive comb fingers.

The deflection shifts the electrical capacitance by fractions of a femtofarad. The chip's analog front-end converts this capacitance change into voltage, feeds it through an Analog-to-Digital Converter (ADC), and passes raw angular rates to the flight controller over SPI or I2C.

2. The 8.2 kHz acoustic exploit

Every physical structure suspended on micro-springs has a mechanical resonant frequency.

In a 2015 USENIX Security study, researchers tested 15 commercial MEMS gyroscopes. Seven were vulnerable to acoustic resonance. Gyroscopes from STMicroelectronics (like the L3G4200D) resonated in the audible band between 2.5 kHz and 8.2 kHz along their X and Y sensing axes.

When airborne sound matches that mechanical resonant frequency, the acoustic energy transfers directly into the silicon lattice.

The proof mass vibrates with severe physical amplitude. The sensing comb fingers saturate the ADC to its maximum railing limits, feeding false angular rates into the flight controller.

3. Why the drone drops

The drone's flight controller runs a proportional-integral-derivative (PID) loop at 500 Hz to 1,000 Hz to maintain level flight.

When sound noise at 8.2 kHz hit the gyroscope, the sensor reported massive erratic rotation spikes. The PID control loop immediately tried to counteract rotation that did not exist.

In real-world flight trials, the controller responded by throttling motors to their minimum and maximum limits simultaneously. The drone lost balance and dropped to the ground instantaneously on all 20 test flights.

4. The same physics in the datacenter

In 2018, researchers at Michigan and Zhejiang demonstrated the same physical failure mode on enterprise hard disk drives.

In a mechanical hard drive, the read/write head floats on an air bearing less than 10 nanometers above spinning magnetic platters, with track widths narrower than 75 nanometers.

Playing an audible 5.0 kHz tone at 115.3 dB SPL caused tracking errors on Western Digital drives. Pumping that tone to 117.2 dB SPL forced off-track vibrations so severe that the drive firmware halted all write operations to prevent physical head crashes on the platters.

With sustained acoustic noise, operating systems experienced complete I/O timeouts, remounting ext4 file systems as read-only.

5. The physical constraints and modern defenses

Acoustic attacks have clear physical limitations:

* Inverse square law: In the drone flight trials, researchers attached a small speaker 10 cm directly above the flight controller at 113 dB SPL. Projecting that sound pressure over 30 meters would require a 140 dB directional acoustic device (LRAD).
* Axis isolation: Modern InvenSense gyroscopes resonate in the ultrasonic range (above 26 kHz) along the Z-axis only, which flight software easily counteracts by cross-checking magnetometer yaw data.
* Mechanical dampening: Wrapping the IMU in dense silicone grommets or acoustic foam blocks airborne sound pressure before it hits the silicon package.
* Asymmetric dual-IMU fusion: Pairing two gyroscopes with mismatched mechanical resonant frequencies (such as 8 kHz and 26 kHz) allows flight software to identify and drop the saturated outlier.

Software algorithms cannot filter a corrupted sensor measurement if the silicon spring itself is physically vibrating.

@trq212 I'm not sure if you're aware https://t.co/Np1GMyWAwh but this is crazy, stalled sessions for hours, just because the harness/tool can't generate sane commands

[ynezz @ynezzor]

I guess we all need to show our preferences with our wallets. In the current situation that basically means if you drive a Tesla or use Starlink, you're a MAGA supporter. Two idiots ruining the technological progress of the whole society.

Those safeguards are annoying, feels vibed, triggering on ~95% of legitimate use cases for me (unit tests for security fixes), making the SOTA models unusable. Makes me discover other harnesses and models and I don't plan to return back anytime soon, the gap isn't huge

Design decisions are the most expensive ones, so Fable is worth every penny. I'm iterating like 10% slower, but with less slop and more usable results out of the box. Current Fable limits are tight, but I'm already paying API token price, because it saves a lot of time.

[ynezz @ynezzor]

Indeed, Sol/Opus looks like great work horse models. They need to be managed by other models like Fable with human interface. Fable writes plan where Opus 5 supervises Sol workers and reviews/gate their work, escalates back to Fable which can telegram me if needed. Gas Town v8?

[Kun Chen @kunchenguid]

i just realized that i'm starting to categorize LLMs into 2 buckets

1. the models i can tolerate directly talking to

for me, these are currently (sorted by how much i want to talk to it)
- grok 4.5: fast, pleasant, does what you ask and get shit done
- fable 5: wise. very wise
- kimi k3: closest 2nd choice to fable. quite slow and expensive
- opus 4.8: the old faithful

2. the models that can do great work in the background, but i can't stand talking to it

- gpt 5.6 series

whenever i directly talk to it, "poor judgment" is the word that comes to mind. it'll miss easy paths and prefer over-engineering. it'll infer intent from my words and go rogue into a whole set of things i didn't want it to do

but.. if i let another model talk to it, then this is probably the strongest architect and system engineer there is. it can come up with very robust processes and methodological approach to solve very complex problems and build reliable systems

- opus 5

if i talk to it directly, it jumps into conclusion without thoroughly investigating context. it can't stop talking about its own honest mistakes. it also creates long walls of text full of jargons

but.. if i let another model talk to it, then opus 5 can build tasteful products and relentlessly chase after a set vision. it's likely heavily trained with very long horizon tasks and that's what it does really well

so we may be entering a world where we have to be very intentional in setting up a multi-agent system where we humans talk to the most pleasant models directly as a friendly proxy to the "nerds" that are insufferable to talk to but can solve hard problems for us behind the scenes

does that resonate with your experience?

[ynezz @ynezzor]

Fable is great in making this token efficient, limits context, turns etc. I like how it benchmarks the managed models, asking them for review of the plans/actions, counting tokens etc. Self-improving skills after 3-4 such iterations.

Involve government in the IPO marketing phase ✅

[Anthropic @AnthropicAI]

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.

The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.

Access to all other Claude models is not affected.

We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

@esrtweet You could publish a restoration skill, which would generatively transform the given old binary. It might be reusable on other games as well. I just ask clanker to create it for me from logs of previous sessions.
