Tom's Hardware ☛ This illuminating Raspberry Pi Pico project wants to improve your photos and YouTube videos
The LEDs are easy to control using the GPIO on the Raspberry Pi Pico via a MOSFET. The settings can be adjusted using a series of push buttons that are mounted to a custom PCB. The hardware is assembled together using a 3D printed mounting component that Sharma designed using Fusion 360 just for this project.

Tom's Hardware ☛ 'You can now jailbreak your AMD CPU' — Google researchers release kit to exploit microcode vulnerability in Ryzen Zen 1 to Zen 4 chips
The exploit affects all AMD CPUs using the Zen 1 to Zen 4 architectures. AMD released a BIOS patch plugging the exploit shortly after its discovery, but any of the above CPUs with a BIOS patch before 2024-12-17 will be vulnerable to the exploit. Though a malicious actor wishing to abuse this vulnerability needs an extremely high level of access to a system to exploit it, those concerned should update their or their organization's systems to the most recent BIOS update.

Ruben Schade ☛ The Speccy
I grew up on DOS and Windows 3.x machines, so all my 1980s home computer adventures have been retroactive. Retroactively awesome. But while I have way too much knowledge of the 486, developed an obsession with Commodore 8-bit kit, and later bought the same Apple //e Platinum my first school had… I know comparatively little about Sinclair and their cute little machines. It was so much fun reading the Wikipedia post over coffee this morning.

Rachel ☛ More thoughts on the 1670 modem's weird noises
To be crystal clear: this is not pulse dialing. That sounds completely different, and besides, I didn't tell the modem to dial anything. I sent it "ATD" which basically means "go into originate mode without actually trying to generate any pulse or tone signals - just grab the line and start listening".

Herman Õunapuu ☛ I yearn for the perfect home server
In my case, low power means less than 5 W while idling, 10+ TB of redundant storage for data resilience and integrity concerns, and performance means about 4 modern CPU cores’ worth (low-to-midrange desktop CPU performance). I seem to only ever get one or two at most.
