It would've been cray-cray to boot them from a single board with extra flash via SWD. Does anyone know how fast the RP2040 SWD clock can be driven on a Pico soldered to a central board? How many DMA channels and PIO state machines woul

This looks like a para-virtualised GPU driver and probably more similar to accelerated indirect OpenGL rendering than PCI(e) passthrough.

Maybe because you have different requirements and preferences (than running CUDA applications)?

Do you still have the core dumps and messages to stdout/stderr/dmesg?

You could use the DMA engine to reconfigure the function routing using a pair of DMA channels.

Tons of networking components contain microprocessors, microcontrollers and programmable logic with excess capacity for their role and could hide implants in software, firmware or even bitstreams without changing a single part of the hardwa

You can't use the deduplication and compression which amplifies bitrot if your memory is (too) suspect and backups don't help you unless you notice the problem quickly enough. Unreliable memory can corrupt your data in ways you wo

WRONG! ECC has caught what would've been random crashes and data corruption twice on my personal workstation that I noticed (detected and corrected). I've seen 100s or corrected ECC errors over the years on my servers and even few

I guess we can put Moore's law to it's final rest beside him.

While local NVMe SSD raids can max out a PCIe 16x slot with given large enough blocks and enough queue depth they still can't keep up with small to medium sync writes writes unless you can keep a deep queue filled. Lots of transaction

Lacing cables together isn't worse than running them parallel using other means e.g. velcro loops unless you're lacing them tight enough to crush the cables.

Less operational complexity. VPN overlays for remote management, realtime peer to peer video and audio streaming, etc. just work reliably. You also get to build the address plan to fit your (business) requirements instead of working around

The author is known to blog his notes using FreeBSD as a daily driver for things other than just damn fast HTTPS video streaming and ZFS file or block storage.

You mean something like a git annex enabled branch tracking mirror locations of each release artifact like HTTP URLs, (webseeded) torrents, maybe even something content addressed like IPFS? sigh

What do you think made Intel Sandy Bridge to Skylake cores so dominant in single thread performance? It wasn't the great amd64 instruction set. Most of it came down to good implementation in a state of the art process node.

Where is your shiny rust kernel and userland useable as desktop/laptop or server? Don't pull others down just because you have yet to deliver.

Intel managed to kill off two competing architectures with Itanium only to get taken out by AMD in turn. Karma is a bitch.

You're right. I forgot that WireGuard sits on top of UDP.

I've found that they work just fine. In my case all that was required was setting a DHCP option pointing them at their controller. The QoS to make it work well under load would've been the same for a L2 tunnel.

IP over Ethernet over VXLAN over UDP over IP over WireGuard over UDP over IP over Ethernet… sigh OpenBSD does support both routing domains and multiple routing tables and includes multiple routing daemons in the base system. I would recom

It's neat when writing assembler e.g. add a scaled byte value to the PC to implement a jump table or perform a scaled and indexed load to the PC. In ARM it also produced a neat short and fast function prologue/epilogue. In my opin

I missed the On the Metal podcast and hadn't noticed the Oxide and friends format until a few weeks ago. It just ended without any hint as to what if anything to expect next. I really enjoy it when the conversation goes of whatever scr

And why shouldn't this engine accept SQL queries as well if it's accessing existing SQL databases (probably just with different weights, retries, and batching/spooling)?

Part of the problem is that existing ISAs have been (and still are) underspecified. At best software was software was written against observed implementation behaviour. More commonly software wasn't written against any (formal) specifi
