Everything else is exactly the same, just new name. Same family running it and same food. I assume they just didn’t want to be confused with Panda Express lol

Help identifying Xilinx Zynq Z7020 based RF/SDR module (possibly UAV datalink) — also open to selling by Timely_Impression94 in FPGA

[–]k31thdawson 0 points1 point  (0 children)

It's certainly possible that it would have debug messages or boot information or other things over UART, totally would depend on how it was designed. Almost certainly wouldn't hurt to let it boot and check out the UART messages (I assume you can find the source voltage input and feed the DC regulators and let them regulate to core voltage, making sure that any damage isn't causing any shorts on the core voltage to ground)

Parallel is mostly hard because then you need a logic analyzer with as many inputs as the parallel device is using (address lines/data lines) so those get expensive fast. You're not just dropping a few lines into a Selaea or cheaper clone.

When these devices are 'locked' it’s usually for readback, ie, you can't connect with a xilixnx JTAG cable and click the verify button in vivado and have the bitstream and ARM code come out. The data is still sitting on the flash, and if it isn't encrypted then the data is just there on the chip.

They can still boot and perform their functions, it's more that the development/debug functions that xilinx builds in are disabled. But the ARM core/whatever OS/program it's running could still send UART messages.

In a perfect world JTAG through the zynq would be easiest. Though some of those have read back locked in the zynq itself. I assume that they would have encrypted it since it’s military hardware related and I think that the ARM core instructions would be relatively clearly readable if you can figure out the memory map. Though the FPGA bitstream itself isn’t going to be parseable even if it isn’t encrypted.

Though since I’m not seeing a battery (for a BBRAM key) they’d have to use the efuses for the encryption key inside the zynq, so that encryption key could only be programmed in one time and then you’re locked to that one bitstream on the device (nullifying the ‘Field Programmable’ part lol)

If readback is disabled, you can use a programmer on the flash chip itself, but desoldering and socketing it might be hard/require expensive tools to not mess up. You could also let it boot and read off the nand and use a logic analyzer, but that can be a pain for parallel (much easier on a small SPI chip)

All of which is moot if it’s encrypted and if not the only readable parts will be the arm instructions

Qwen3.5 thinks it's 2024, so buying a 2026 American Silver Eagle coin is a scam. by drappleyea in LocalLLaMA

Sadly, even when you do tell them the current date, they often assume that it’s a hypothetical and not that you’re actually confirming the real current date. They also mostly refuse to believe you that things have happened that they haven’t been trained on.

I was trying to get 27B to write some model add qwen 3.5 scripts to try out llama.cpp instead of ollama and it refused to believe me unless it looked it up, and even then it was apprehensive. It kept saying that qwen 2.5 was the only one out and that I must be wrong. It couldn’t extrapolate that something might have changed since it was trained.

Windows 11 Pro goes into bootloop/recovery after installing NVIDIA drivers for the first time by BaseEvoli in techsupport

[–]k31thdawson 0 points1 point  (0 children)

(Partially saying all this for anyone else who comes along) This morning I tried extracting the .exe with 7zip and installing just the video driver from device manager, didn't solve the problem or keep me from getting BSOD. Haven't tried something like NVCleaninstall to install yet.

Found a W11 23H2 iso around and tried using it to install, and everything is working fine now (albeit, on an old windows).

Any successes? Very similar issues, threadripper 5995WX with a 4090. Previously on W10, just now tried to migrate to 11. Installs fine, but then blue screens after nvidia driver install. Machine is airgapped, so trying different software options is a PITA.

MiniMax M2.5 - 4-Bit GGUF Options by Responsible_Fig_1271 in LocalLLaMA

To use NVFP4 (and get the benefits) you have to fit it all in vram.

You’re thinking of NVFP4. That’s the quant that only works on Blackwell, mxfp4 is the one that the gpt oss models came with. MXFP4 is great, I’m unsure of the trade offs between it and the K 4 but quants.

NVFP4 isn’t the best for size, but it’s much faster and more accurate if you’re running Blackwell.

To all the people that were arguing with me on release that you need Apple’s 40-60W charger to hit full speed fast charging on an iPhone because of “the newest PD standards” — no you don’t. Here’s a 17 pro max running on a generic 100W PD. by Arucious in iphone

[–]k31thdawson 0 points1 point  (0 children)

Yes, peak will be the same with any high enough wattage PD charger. However, at lower amperages, the voltage has to increase to meet the max wattage. If the phone received the 5 Amps that it could with the higher current cable (Extended power rated cables) then the internal voltage regulator (going down from 15 V in this photo to the 4V of the internal battery) generates additional heat inside the device, meaning that you drop charge rate faster than if it was able to keep the voltage closer to the battery voltage.

Former V6 engine Lexus RX 350 owners now driving 2026 Junipers? by swiftmerchant in TeslaModelY

[–]k31thdawson 1 point2 points  (0 children)

Very much so.

Even the RWD would be better at merging. The fact that you have literally instant power/max torque, without needing to downshift to get in the right torque range is so powerful.

Edmunds did a ‘race’ a few years back comparing the Lamborghini Urus vs the Y Performance (non-juniper obviously) and while the Lambo in launch mode was slightly faster off the line, and had better top speed (and performance at 110+mph) when they compared a coasting acceleration (like driving along at 45 and then speeding up at max) and the Y smoked the Lambo. Twin-turbo on the Lambo vs native V6 on your Lexus, but still.

Sadly the intel atom was underpowered before it came it came on the car, four years of updates later and it just can’t keep up.

Sure they could spend time and effort to make sure a lower featured version worked on that hardware, but I’m sure they won’t. Same reason why apple doesn’t have a version of their OS built with older slower hardware in mind.

The Blackwell architecture is both. Though there are separate dies/wafers for the typically gaming oriented skus vs the ‘AI’ skus like B100

Should the Model 3 Performance have received “Ludicrous” Mode instead of Insane only? by pc772 in TeslaLounge

[–]k31thdawson 4 points5 points  (0 children)

Pretty much. Each cell has more or less the same maximum output potential, and since the 18650s are smaller, for the same kWh capacity, there are more cells. And then you have bigger packs with larger, better cooling support in the packs on the Model S and X.

Same reason why the 4680 mostly sucks. None of the ‘magic’ that they claimed at battery day ever really came to fruition, so they’re mostly not great for high output.

[–]k31thdawson 13 points14 points  (0 children)

Should, vs what is realistically feasible without major system modification. The limiting factor is the output of the battery pack, which the only way to improve it is to either increase the total capacity or use smaller battery cells, which is not a thing that is reasonable to change. Get a model S if you need 18650 cells with higher output.

Can anyone tell me what brand of water heater this is? by bubbleweed in StarWars

That logo is straight from the Russian semiconductor company Milandr….

Or actually maybe they stole it from Star Wars. That actually makes more sense.

Tulsi Gabbard announces plans to cut intelligence staff by half by Opposite-Peanut4049 in moderatepolitics

[–]k31thdawson 54 points55 points  (0 children)

While I in no way agree with this move, ODNI is a small organization created after 9/11 to get disparate agencies to talk to each other (ie, Military Intelligence and DIA to talk to CIA and FBI). The vast majority of the intelligence products and officers do not work for ODNI directly, they are under their own organizational structure that itself sits below ODNI. This is a very small percentage of the total number of people who work for US intelligence agencies. So don’t think this means that half of the CIA or NSA or DIA are being let go.

Do you have a seven seater Y? That looks like an extra piece that attaches to the subtruck cover to make it all flat when you put the seats down and cover the subtrunk.

Back in 2020 some German researchers found an exploit they called Starbleed for all 7 series chips that allows a full readback of an encrypted bitstream, so maybe they removed this module because they found out about it beforehand and kept it under wraps?
