My nephew just graduated high school, and wants a laptop. When he decides what computer to buy, price (or more precisely, value) is the most important attribute.
Apple's MacBook Neo upended the 'value laptop' equation—Apple's not supposed to be both the cheapest option and the best value... but it seems like that's squarely where the Neo landed for the good-but-cheap laptop category.
My nephew is also my godson, and to kick off his computing journey, I thought I'd let him choose from a Framework 12 I bought to test, or the MacBook Neo I bought a couple months ago to use around the studio.

Pooch from Repkord dropped by my studio while he was in St. Louis, and asked a simple question:
Can a 3D printer's heatbed act as an antenna?
A fair question, as many an antenna is embedded in a PCB these days... and the traces on a PCB heatbed like the one used in Prusa's Core One look kinda like an antenna, if you squint the right way.
Really, anything (or anyone) can be an antenna, given enough power.

A decade ago, I settled on iozone for disk benchmarking on all my systems. Tools like fio ('Flexible IO' tester) are a little more capable for raw disk performance testing, and other tools test network-scale filesystems better, but iozone gives me an easy overview of real-world disk performance across hard drives and SSDs, and runs on Mac, Windows, and Linux (and a smattering of other OSes).
It's been around since 1991, and is still updated today—in fact, the two latest updates (version 509 and 510) contain patches I sent in to get iozone to compile on Apple Silicon Macs running newer releases of macOS.

On Thursday, three of the lead Raspberry Pi engineers hosted an AMA on the r/engineering subreddit.
One of the most interesting tidbits was on the Pi 6.
Looking back at previous launches:
Following that cycle, one would expect a Pi 6 3-4 years after the Pi 5, which would put it in 2026 or 2027.

At NAB, I found a demo of Wi-Wi STAMP, a wireless time synchronization protocol that came out of Japan's NICT.
Wi-Wi stands for Wireless 2Way interferometry, and it uses the 900 MHz band for picosecond-level time sync, and mm-level distance accuracy, in a tiny box, currently the size of a smartphone.
The system is still in development, but existing prototypes have 20ps of phase synchronization jitter, and time synchronization down to 30ns. The next generation will have time down to 5ns in real-world use.

Last year I said I'd probably never recommend another Bambu Lab printer again.
I still use my P1S, but after Bambu Lab started pushing their always-connected cloud solution as the new default:
I had to do that to keep it under my control, instead of Bambu's.
