researcher @log4j just published a teardown of samsung’s TV sensor telemetry. Here’s what the logs show.
samsung TVs without a built-in microphone look for connected devices that have one soundbars, bluetooth speakers, anything paired. They use that mic instead.
the audio isn’t sent raw. it’s classified first. the telemetry path includes named event types:
— EV201/SOUNDSENSOR_ON: logs dog-barking and baby-crying counters
— EV101/LIGHTSENSOR_ON: software flag for ambient light state
— EV301/CAMERASENOR_ON: camera-state and notification fields
— EV302/CAMERASENSOR_OFF: camera streaming duration
the data is formatted as key=value pairs and logged to lcprd1.samsungcloudsolution.… with deviceid=1.
it’s not recovering unique identifiers per device — the ID mode is configured but the module prefix and runtime policy still need independent verification.
what is confirmed: samsung’s TVs are classifying ambient audio including whether a dog is barking or a baby is crying in your home and reporting event counts back to samsung servers.
there’s no wake word these are passive environmental audio events being counted and logged.

black october just got worse. a japanese company lost 27,000 servers and it’s not even the scariest part
GMO Internet runs a cloud service called Onamae Desktop, mostly used by forex traders running automated trading bots
hackers broke in, installed malware across up to 26,739 servers, stole trading credentials and started making unauthorized trades on people’s accounts
not one broker. over 70 different securities and forex firms across japan and internationally. people woke up to trades they never made, money moving they never authorized
OANDA Japan froze customer withdrawals. GMO refused to pay the ransom, permanently shut down the entire service, and did something nobody expected
they asked the japanese government to use brand new active cyber defense powers, literally military-grade authority that just went into effect october 1st, to trace and neutralize the attackers’ infrastructure. the government can now legally hack back
the technical details from the attacker’s own site are terrifying. GMO configured their VPS network using Active Directory, something you should never do on shared hosting
every server had admin credentials. and the RDP files customers used to connect? drive redirect was enabled by default, meaning the moment you connected to your VPS, your entire local PC was shared with the server
hackers didn’t just own the servers. they had a direct path into every customer’s personal computer. they extracted data, installed backdoors. customers were exposed like this for over 7 years
27,000 servers. 70+ brokers. unauthorized trades. personal computers backdoored. a company begging its government to go to cyber war
october isn’t slowing down

American comedian Sammy Obeid was detained by Japanese immigration authorities and denied entry to the country because he was going to do a paid comedy show without an Entertainer visa.
If someone enters Japan as a tourist, they aren't legally allowed to do paid shows.
The Japanese government denied me entry and held me in solitary confinement for 24 hours over a standup comedy show with 40 attendees…

The poster was denied entry for planning to perform ticketed stand-up comedy shows, an activity requiring Japan's Entertainer visa/status and prohibited under Temporary Visitor (tourist) entry.

Reminder: traditional computer graphics alphabet is in reverse order:
- xyz, the 3d axis.
- w, the component of homogeneous space.
- uv, (because zyxw were taken) the implicit 2d parametrization of surfaces.
- st, (because zyxwuv were taken), the user defined texture coordinates

Never deleting this app.
aren't you the moron that exposed your API keys on stream/uploaded your .env files and lost $90,000 and cried about it on your X lol

DeepSeek just published the price of a token, and it should make you angry.
From their own DeepInfer docs: 1 cluster serves 155 trillion tokens a day, at $38 of revenue per GPU-hour, and thats at off-peak prices. Their API is $0.30 per million input tokens and $1.20 per million output at peak.
Yuchen Jin did the math: even if they rented B300s at $7 an hour, thats about 82% gross margin. Other estimates go higher.
So cheap AI is not charity and it is not "dumping". At these prices serving a frontier-class model is a very profitable business, if your inference stack is good enough.
Now remember every time a US lab told you that intelligence is expensive. That $200 a month is a fair price. That limits exist because compute is scarce.
Part of that is true. Part of it is a business model built on you not knowing what a token actually costs.
DeepSeek just showed everyone the numbers and gave away the engine. Every inference company can now compete on price with the same software. Thats how AI gets cheap for everyone.
“A single cluster currently serves 155 trillion tokens/day, generating $38 in revenue per GPU-hour (at off-peak pricing).”
Huge flex from DeepSeek. Not only did they open-source their inference engine, but they also open-sourced their revenue numbers.
They didn't disclose which GPUs they're using here, but DeepInfer supports both NVIDIA Blackwell and Huawei Ascend.
Even assuming they're renting B300s at $7 per GPU-hour, that's ~82% gross margin.

"The swarm's random number generator used double arithmetic that overflowed past 53 bits, and with seed 9 it fell into a short cycle, so every child it bred was a repeat and the main thread spun forever while the eight workers sat idle. The eight-survivor run never got past its first generation."

Update: The Chief Marketing Officer at Autodesk reached out. We have a meeting scheduled for Monday morning.
This is a wild approach, @autodesk.
We’re a small business paying $380 per user, per month. We’ve been paying customers for over a decade, and we make a deliberate effort to honor the license agreements for every product we use. Your software already requires authentication and an assigned license. What, specifically, prompted this email?
Earlier today, I had two conversations on two separate podcast episodes about your direction with Fusion and why cloud-based API access makes sense for agentic MEP workflows. I was making the case for Autodesk. I think the product direction is right based on recent posts from @andrew_anagnost.
Our company has been deciding where to invest our development effort: integrate our custom cloud agent harness into Autodesk, build on an open-source platform, or adopt one of the emerging cloud alternatives. That decision will lock in years of internal development and software spending. This decision is also central to our plans to expand @PermitZIP nationwide.
An email like this becomes part of that decision. So does the time we have to spend responding to it.For more than a decade, we’ve paid for anywhere from 5 to 30 licenses each year. Autodesk is our single largest SaaS expense. This is a heck of a way to make our next platform decision easier.
Starting next week, we’ll begin transitioning away from Autodesk products. We have nothing to hide and will cooperate with the audit. We’ll also be directing our future spending toward companies that earn our confidence as partners.
I hope your audit goes well.
