HBM uses about twice as much DRAM silicon per GB due to all the space for interconnect

I've heard GenAI.mil still has Gemini 2.5 only.

Fake tracking numbers are a common occurrence in scams now. Somehow the scammers are getting access to a database of real time legitimate tracking numbers, they wait until there’s a shipment in their database going to the same city as the buyer, and then use that tracking number to claim that they shipped the package. Maybe they’re paying a real merchant for access to their shipping database? Or are UPS tracking numbers short enough to brute force?

Higher frequency means smaller and therefore lighter transformers, which is very important on aircraft. Nowadays a DC voltage supply would be better, but DC to DC voltage converters didn't exist when the 24V 400Hz standard was created.

For mains voltage we use 50-60 Hz because lower frequencies work better with very large AC generators in power plants and, and lower frequencies are more efficient to transmit long distances.

Apple doesn't want you to know this but they do their mechanical and electrical design on Windows PCs (using Siemens NX and OrCAD respectively)

Wow I'm shocked how cheap this is:

Prices, to keep this data anti public and affective only 5 copies will be sold

price per copy is 400$ [ negotiable ]

exclusive sale, only 1 person : 1500$

if you want to have the data + vulnerabilities we used to get into the database - 2000$

Right I intentionally left off Step 1 from that chart to simplify the explanation, since it didn't seem necessary. Is Step 1 just for creating the ChatGPT content blocker?

A friend's 18yo brother was motorcycling in the mountains with their father, crashed and broke his femur. Ambulance would have taken hours, they had helicopter rescue insurance, but the only helicopter company that operated there wouldn't take it. Got a $25k bill for the helicopter ride and negotiated down to $16k iirc.

> Where did all the money go?

One theory is that the crypto quant funds figured out how to exploit the Alameda FTX market maker starting in 2020-2021 to take tons of money from Alameda. But FTX couldn't just turn off the Alameda market maker because most of the FTX trading volume, and therefore FTX revenue, was these crypto quant funds taking money from Alameda. So if they turned off the Alameda money spigot then their revenue would drop off a cliff and they wouldn't be able to raise more money from Sequoia or the UAE. And the value of FTT was tied to the trading volume and was a huge portion of their assets, so if volume fell they would be insolvent.

Basically they turned customer deposits into revenue at pennies on the dollar.

High impedance (low current flow) signals are more prone to electrical interference. This is particularly bad when you're running long wires across a factory with big electric machines running. And if your signals are low impedance (significant current flow), then you get voltage drop across your long wire, so you can't use voltage-based signaling.

The rumor I read was the entire M2 line was designed for N3 and then that got delayed so they backported to N5P.

Can someone test whether you can do this style of prompt injection to discover what the rest of the prompt is?

This is a whole industry in China. There are buildings in Shenzhen with hundreds of vendors selling scavenged storage and memory chips, because those are highly standardized. And discontinued chips from the 80s and 90s are salvaged and sold on ebay and AliExpress so people can repair their old electronics. I've even seen broken laptops get their CPUs desoldered and turned into desktops with custom adapter boards. They're incredibly creative when there's profit to be made.
