How do you distinguish between input (Keyboard/USB) and output (Browser/Graphics stack) delays in this test?

IIRC ReactOs forbids you from contributing if you had access to the windows source code in some way shape or form.

I've been mounting my 3.5" hard drives on those "fad" rubber band 5.25" drive bay adapters for decades and have not noticed any increased failure rate at all. Sure, seek time may b…

Not OP, but I installed a "Balcony solar" 1.4kWp panels 2.4kWh battery system on my parents garage. The only subsidy was the tax free purchase of the components (we did file for an…

It does say "Certain cough medicines and illicit hallucinogenic substances are also known to trigger it"

BTW looking at the 8051 patch bytes, they look like 8051 code to me. 0x02 is the ljmp opcode, so this is a jump table: 0x02, 0x40, 0x58, 0x02, 0x40, 0x4e, 0x02, 0x44, 0x00, 0x02, 0…

I have the ST one (X-NUCLEO-LPM01A), but its range is actually not enough for something like an ESP32, it goes into "overload" as the max current is 50mA for dynamic (100kHz bandwi…

The partition table listing from the microSD card shown in the video (before installing a custom u-boot/Linux) shows partitions marked as the Linux partition type at least.

The amount of power you can dump for balancing is just a fraction of the charge/discharge power (because it only needs to offset differences in self-discharge rate). So you still n…

In a similar vein, there is https://aminet.net/package/mus/misc/AlgoMusic2_4u.lha , from ~96 or so.

I do actually see the problem that the ESP32 doesn't automatically reconnect to the stronger AP. I think this gets triggered when then stronger AP is briefly unavailable (reboot or…

Athereos wireless cards (ath10k) have also used Xtensa. And the audio DSP in newer intel chipsets (e.g. Apollo Lake) is also Xtensa-based, but unfortunately quite locked down (sign…

RK3568 / RK3588 have 3 SATA controllers and for example the Rock Pi 3A seems to have the SATA routed to the bottom m.2 connector, as well as the possibility to switch the USB3 port…

I think the article in question actually is for older BIOSes that don't have flashback or similar. Instead this relies on the "BIOS Boot Block" still being intact in the flash, so …

DisplayPort is the more surprising one. DDC came from VGA and DVI and uses the I2C lines that also connect the EDID EEPROM, but Displayport doesn't even have I2C pins if you look a…

> 64 registers with 3 registers per instruction would require 21 bits Actually only 18. With 21 bits you can get 128 registers.
