"Process node," in the sense of logic, RAM or Flash density, isn't relevant here. These are power devices. Silicon Carbide FETS and whatnot; bulk current switching and related devices. Not frontier process node logic devic

Yes. There are recently built 747-8's that will in service for a couple more decades.

It just a time limit of the life of a single MicroVM. Using this for a long lived "developer environment" would be extraordinarily expensive anyhow. Scaling the vCPU + RAM cost of these to the same shape compute optimized Gravito

Answer that question and you'll get the whole impetus for logarithmic scales.

It's a lab. It's where ASML brings up the prototype machine and gets it working, with IBM talent working out the problems and getting it ready for commercial operation. They won't make chips at scale there: the facility isn

I have also been thinking about this a lot, and share your belief that this is inevitable. Taalas has a running demo here: https://chatjimmy.ai/ It's eye opening: generated an AVX-512 optimized Mersenne Twister in C in

That only applies for network sockets, and requires taking responsibility for the entire network protocol stack. Not something that should be done without a very compelling reason, and not applicable at all in this case, where storage devi

Classic. Know that the increase in CPU utilization may mean you've improved the performance of your "database server," because now your CPU cores are waiting less on IO. It also may not mean this, but just looking at htop

It is tragic. Another repetition of Hoare's Billion Dollar Mistake, exactly where it should not have been made, long after the consequences were well understood, and also previously repeated at the time Go was conceived. There really

Is this some xBSD or UniFi OS (debian) with ZFSoL? Can't tell from what they've written. 8C+64GB: enough for essential block+file service, but not for dedup and other demanding ZFS features. Also, doesn't appear the contro

These can deliver 2.5-3A/phase, which should ample for a pump. Respectfully, I wonder what motor was involved and whether the current was configured: they come out of the box with conservative configuration so people don't burn u

Across the board TI is moving to new fabs, new fab processes and 300 mm wafers. So the old tooling is going away and they're adapting legacy designs to the new processes. This changes component behavior, particularly analog stuff, li

You see this in low cost products like MKS SERVO42x, where they're doing FoC with a GD32 MCU. It works; the motor runs cool, smooth and quiet, but the system is limited to 3000 RPM, and struggles with rapid acceleration because the co

This is how Jeroen Domburg, Espressif Technical Marketing Manager, addressed this matter in a post on hackaday.io: "We actually never intended the CPU architecture to be part of the name, as for 99.9% of all users, it doesn’t matter: y

Espressif is all-in on RISC-V, expanding their portfolio of RISC-V devices where they previously had only XTensa: ESP32-S31 is the first big departure from the coincidental alignment of ISAs within their product structure and definitively e

Field-oriented Control schemes modulate phase currents at high frequency; the feedback loop must be much faster than the motor phases. Until fairly recently, this stuff was the exclusive province of dedicated ICs (Trinamic et al.) and FPGA

S has never implied Xtensa, and C doesn't imply RISC-V. That's a widely held misunderstanding. S, C, P, etc. are product categories, not ISAs. S devices are high performance SoCs; large feature set, high frequency, not the lowe

I'm excited that this MCU and the P4 has RISC-V CLIC. That puts it at least on par with Cortex NVIC and enables bare metal frameworks like Rust RTIC to work really well. Also 4x MCPWM peripherals; that's a first for any Espress

Roku remotes are sophisticated devices. There are many models, so features vary, but among the possible features are 3.5mm audio output, Bluetooth audio, voice command input, Wi-Fi, infrared, battery charger and other things. Clearly a su
