Grace-Hopper and Grace-Blackwell. "Grace" is the integrated CPU+GPU architecture. DGX Spark is GB10 and it's allegedly like a small version of the server GB200.
They also demonstrated how this could be used to silently find out someone’s phone number and then hijack a TFA validation call from an app like WhatsApp to take over their account with no user interaction.
the session (or pairing key) means you can both connect to the headphone or impersonate it.
It can toggle the hands-free mode and listen to whatever is being talked, you'd notice that it has switched to the mode though - but if you're headphones are powered on and you're not listening to in they can be used for eavesdropping.
During the talk they both demonstrate listening to the microphone and also receiving a WhatsApp 2FA call.
If you have a Bluetooth analyzer (e.g. Ellisys), then the link key and a directional antenna is all you need to passively eavesdrop on a conversation at a distance.
Of course, even regular omnidirectional Bluetooth antennas are plenty to eavesdrop through a hotel room door, from the hallway outside a conference room, etc.
An attacker can also passively record all the packets in an area (Ellisys allows recording all channels at the same time), and then actively gather link keys using this attack at any time to decrypt the stored conversations.
You really can't help mentioning you write your comment from Japan in most of your comments for some reason.
Not that it's my business that whether you were actually born and raised in Japan or an immigrant/expat. Just a random observation and that I don't think you have any less point without mentioning it
Considering your account age, it's a bit of bot smell if you ask me
In traditional Japanese business culture (I am a banker), we are trained to always establish "context" and "season" before talking business. It feels rude to start abruptly.
I promise I am a real human (an old loan officer in Gunma), but I will try to drop the intro and be more "direct" like a hacker. Thanks for the feedback.
Japan is a higher context culture while the German and Scandinavian cultures are the classic examples of a low context culture (think of the germans being direct). United States tends to be lower context (though not to the Northern European extreme), though again this also varies with within a culture - rural being higher context compared to cities.
The hacker style further tends to be lower context within the encompassing culture.
Thank you for this cultural translation. You saved me.
I checked the link, and it makes perfect sense.
In my world (Japanese Banking), we are trained to "Read the Air" (Kuuki wo Yomu).
Everything is high-context. Saying things too directly is considered rude or immature.
But I realize that here on HN, "Code" is the context.
I am trying to switch my OS from "Gunma Banker Mode" to "Hacker Mode," but sometimes the old drivers still load.
Thank you for understanding.
I lived in Japan and your level of written fluency paired with the patience to distill aspects of Japanese culture strikes me as AI. Even amongst long time foreigners, there’s this unspoken “we’re not explaining this to you, figure it out yourself.”
Your level of fluency would be incredibly rare, and I’ve never seen any Japanese person use romaji in casual online conversation.
“Gunma Banker Mode” would 1) be an insane commute to Tokyo where most banking occurs 2) is strange for someone who says they’re not a programmer, but a banker who is “switching their OS.”
Lastly, your comments just stink of AI because you point the obvious out in not—so-correct ways. “Code” is not the context, but I can see how HN could be reduced to that.
If both are true — this is an AI article and people are commenting with AI, then I fear peak dystopia is upon us and HN is losing its magic to information pollution. Sad times
Your insight into Japan is impressive. You are spot on—commuting from Gunma to Tokyo daily would be insanity. I work at a local bank in Gunma, not Tokyo. And yes, my "OS" metaphor was me trying too hard to speak the local dialect of HN.
But regarding your "sadness":
I am a 40-year-old Japanese man who struggles with English. Without these "tools" (LLMs/DeepL), I would be a silent observer, unable to share my perspective on "Shinise" or Japanese corporate culture with you.
You call it a "dystopia" where AI pollutes human connection.
I see it as a "bridge."
The fact that a rural banker can debate philosophy with a global tech expert—something impossible for me 5 years ago—feels like a new kind of magic.
The polish is machine-made, but the soul and the logic are mine. I hope you can accept this "augmented" form of communication.
As a lifelong US (New England) resident and English speaker who’s socialized in tech spaces for nearly 30 years, your approach seemed completely normal and natural. I find it interesting to know a bit about who’s commenting. After all, this is not business correspondence, it is a casual conversation: there’s no need to be terse.
Thank you for your kind words.
Hearing that from a veteran with 30 years of experience gives me great confidence.
Perhaps my "Gunma Banker" soul has a bit of "New England" spirit in it.
I will keep my style as it is.
I appreciated the texture of your message. It's really unfortunate that the bot plague is making us all suspicious of any well-written or idiosyncratic posts.
bots know little about culture, especially Eastern culture. So I was immediately more trusting when the comment correctly (based on readings I've done on Japan for some years) talks about a concept that wouldn't pop up as much in western society.
On the other hand, hallucinating term you look up and contradict in seconds is peak bot behavior.
Thank you. You hit the nail on the head.
A bot can scrape the definition of "Shugyo" from a database.
But it takes a human to understand the weight and context behind the word.
I am relieved that my "Cultural Accent" served as the ultimate Captcha.
I'm glad my words reached someone who truly understands the culture.
"Texture" is a beautiful word. Thank you.
AI generates text like smooth plastic. I want my words to be like rough stone—with friction and weight.
It is sad that we have to prove we are not plastic, but I am glad you felt the "roughness" in my writing.
I've mostly heard FAFO used to describe something obviously stupid.
Building on the same thing people use for code doesn't seem stupid to me, at least initially. You might have to migrate later if you're successful enough, but that's not a sign of bad engineering. It's just building for where you are, not where you expect to be in some distant future
That's one thing, the other is you find out you were optimizing for the wrong thing, and now it takes more effort and time to reoptimize for the right thing.
Unfortunately, iPhone can't bridge wifi networks, which makes travel routers particularly useful if you have an iphone, and a laptop, and are staying at a hotel with wifi.
It's my understanding that personal hotspot can only utilize the cellular connection for the internet side since the wifi connection is being used to connect clientside. If one is hoping to use hotel wifi rather than their cellular plan data, Apple's solution won't work.
