I'm telling you: we're at a special moment here. The labor savings of open source, the composability, the fun: all of it has come to hardware. You can build things that solve real problems for yourself.
Maybe a poem will help remember complicated power-saving settings for SSDs. Here goes. "ALPM for SATA, not N-V-M-e. The latter needs ASPM, and A-P-S-T"....
This is the Compute Blade, and I'm test driving it in a four-node cluster: I'm testing the Dev version, and @Merocle from Uptime Lab sent four Blades, a 3D-printed 4-bay case (a metal 1U rackmount enclosure is in the works), and two fan modules. He's been testing 40 of these in a rack at Jetbrains for months, and…
Announcing Raspberry Pi 5, coming in late October: over 2x faster than Raspberry Pi 4, featuring silicon designed in-house at Raspberry Pi.
What RISC-V will do is give our customers is an extra option when seeking to minimize power consumption in certain applications where the (many) tradeoffs of not using an Arm-based core are acceptable.
Let’s start at the beginning. What is an FPGA ? Well, FPGA stands for F ield P rogrammable G ate Array , which isn’t helpful in understanding what they are or do but we had to get that out of the way.
If you’re new to the Arm ecosystem, consider this a quick primer on terms you likely have seen before but might have questions about.
Nope, I think this might be the best ultra-low power consumer digital watch ever produced!
It's time to add another family of emulated older technology to the Internet Archive.The vast majority of platforms within what we call The Emularity happens because of the work of MAME Team, which has spent over 25 years adding support for tens of thousands of machines, platforms, and tools to their breathtaking…
As harvest season begins here in the Midwest, I once again celebrate by grinding Nebraska gravel at the Gravel Worlds Long Voyage bike race. As in previous years ( 2021 ) ( 2022 ), I spent more time writing code for a marginally-useful project than I did training. But hey, I finished!
