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 …

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 converter…

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 perso…

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?

The way they went from GPT-3 to ChatGPT is really quite genius. My understanding is that it's something like this: 1. Start with GPT-3, which predicts the next word in some text an…

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, bu…

> 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 Ala…

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 mach…

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

Sorry I saw this on Twitter today and it didn't include it.

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 d…

Wow you're right, GPSTest on my 2019 Oneplus 7 shows L5 GPS satellites, in addition to L1 GPS, GLONASS, Michibiki, and dual-band Galileo.

Making miniature electronics is really hard!

Tesla has been shipping custom 14nm inference chips in cars since 2019. https://en.wikichip.org/wiki/tesla_(car_company)/fsd_chip

With transparent lenses and no tracking, how are these better than the non-transparent video glasses that have been available for two decades and never caught on? The contrast rati…

Today there is $20mm a day of ETH being printed and given to miners, most of which is sold immediately to pay their operating costs. After the merge there will be only $0.5mm a day…

Bigger chips have much worse yields, which is why phone chips get the latest nodes first. No way they launch 3nm with M2 Max. I was expecting 3nm A16 and 5nm M2 Max for release thi…

TSMC and Samsung inflated their numbers a decade ago, Intel inflated their numbers last year to catch up, so now the nm numbers from all the fabs mean roughly the same thing.

Neither CPU company lowers prices unless they have competition from the other.

TSMC was founded as a Taiwan government initiative, the government still owns 6% and has a representative on the board of directors.

USB-A ports output 5V as long as the device is on. But with most USB-C ports, to save power no power is supplied until the device requests what voltage it wants. Requesting 5V is v…
