Great find! One comment on what the article says: > If this were actual code review the correct comment would be something like “this [piece] hasn’t been used for years, it should be deleted”. But this is something in physical space, and

Website seems to have gotten HN’s hit of death, but the headline sounds fun. I’ve also got OpenBSD 7.5 running on a Hetzner server, but it runs “natively”. By which I mean it’s still a VM from Hetzner, but I don’t have my own nested QEMU la

But the AD936x is directly connected to the programmable logic (FPGA) of the Zynq, not the PS (CPU), so you can either do the bulk of your processing (e.g. filtering, demodulation, possibly higher parts of a protocol stack) in the FPGA, or,

I stand corrected (sort of). I did specifically say that you‘d see zero other machines when connected to the Internet over a point-to-point link, but I indeed had no idea that in the US there were cable modems from different subscribers w

This is the correct answer. Broadcast packets do not reach outside of a network segment. The “thousands” of Windows machines OP saw were probably part of the same office network they were sitting in (where other mechanisms may actually have

Having read the data sheet now, using the DMA Sniffer's accumulation mode to generate PSRAM addresses is pretty genius.

I don’t even find Vivado that bad, but maybe I have Stockholm syndrome. Or maybe it’s because I’m forced to use Intel Quartus right now and wish it was Vivado every time.

What parts do you have to fight? I’ve been using Zynqs for about almost a decade or so, and I really enjoy them. But that’s for personal projects with a lot of freedom, so I’m curious what problems arise in more commercial/professional

For anyone who might not know, UUCP literally stands for "UNIX-to-UNIX copy". Of course, especially given its relative simplicity, at some point non-UNIX systems started to implement it (I think I maybe used some DOS package at so

Yeah. And we ultimately all quickly settled on the ISO-like format YYYY-MM-DD (with optional and varying delimiters, it does not have to be exactly ISO), which makes the most sense of all because you can just lexicographically sort it (e.

No, I think they tried to correct them about that by saying "J is also up there" (implying "in contrast to Julia"), but I agree that that wasn't very clear, and that your clarification, even if it was under a wrong

It’s a bit trite to call out the next nesting step, but in this particular case I’d really like to see original TECO emacs running in modern emacs TECO.

Coincidentally, I just used a veritable litany of bind mounts this week. I did not attempt to hide anything, though one of those bind mounts exists in order to fake something. I needed this to be able to properly run some x86 software under

Thanks. This got me curious enough that I'm now reading the datasheet. It seems exciting enough that I may likely choose it for my next project that requires a microcontroller. (When I don't want to use FPGAs, which I tend to over

Awesome project indeed! Since I have you here, what is the "DMA Sniffer" that you mention in your doc? A very quick search on the Internet didn't reveal too much.

This project is an emulator that is able to run NetBSD (and Ultrix, and Linux, and potentially others)!

That indeed sounds promising.

Without an offline history and sane support for multiple clients, it does not really have the same utility. I’m using IRC, but oh my gosh is it a pain to set up and maintain. Bouncers are terrible, so the alternative is IRC clients that bas

Granted, I wasn‘t aware. But unless you also have to tell CP/M how many cylinders and/or tracks you want to allocate for your „file“ upfront, and how large the (single!) extent should be should that allocation be exceeded, as well

I think those things are largely orthogonal, though. Opening a file can be simple, while not everything having to be a file. So, having the concept of files at all (and simple to open ones, to boot) is of course much better than MVS dataset

Yes, AS/400 / IBM i is the other IBM OS I like to play with (I have an actual AS/400e at home), and in a lot of ways I consider it to be the polar opposite of MVS on the mainframe: Where MVS seems to be missing very simple ab

If you want unfamiliar, try MVS on IBM s/370 mainframes. Version 3.8j (from the early 80s) is readily available, and runs great on the Hercules emulator: https://www.jaymoseley.com/hercules/installMVS/iMVSintr
