Yeah, I've been considering just going for an x86 thing, though finding a mini pc with 4 satas might be tough, and there's the whole raspi ecosystem that would help with troubleshooting. I'll add that to the potential list though =)

The easiest way might be getting an ITX board with N100/150 from CWWK or Topton. They usually come with 4-6 SATA ports and the CPU soldered on. Then you just buy your favorite case and plug in your drives. Excluding the cost of the drives you might end up spending about $250, depending on your case and PSU selection. The problem with using SBCs or mini PCs that way is that you need an enclosure to hold, power, and cool down your disks, and even that is assuming that you can actually connect them via a SATA/SAS connection which may not be easily available from within your case.

Looks like the Radxa CM5 is still significantly faster than Pi CM5, while only being slightly more expensive (113USD vs 95USD for the 8GB/64GB model from what I could find). Anyone here has any experience with it?

In theory you can use the WiFi-One, though I don't know if that one is BIOS-locked. I just use it with USB3 and a 4 Bay Enclosure, which probably someone is gonna explain to me is the worst idea since leaded gasoline, but I have absolutely no Issues with my ZFS NAS for 5 years that way.

Over on reddit I once floated a similar idea but everyone exclaimed that USB enclosures sucks and you should not use them at all. Now technically you could - with some PCIe expansion cards - connect SAS/SATA HDDs to the ports on your mini/SFF PC, but then you need an enclosure for holding, powering and cooling the disks. Holding and cooling is simple enough and there's enclosures on AliExpress that cost like 10 bucks that do it for you, but you'd still need a PSU outside of the PC to power the disks. At that point the USB enclosure starts looking even more enticing.

Which one are you using right now? There's some brands out there that are considered really bad by the community.

I took a strange career jump recently into FPGA engineering with a focus on Ethernet. It's been a fun journey, which culminated in me finally designing my own Hard MAC IP and sending a packet over some custom PHY IP. I'd highly recommend it for those looking to try a "Hard Mode" version of this challenge. I feel like networking is very abstracted from users, so understanding how Ethernet cards, modems and switches put together and pull apart sections of packets, and how the PHY/PCS recovers signals over a link was really valuable.

Sounds fun! Were you already familiar with networking/Ethernet when you started? If not, which resources - if any - did you use to get a broad overview of everything involved? My knowledge of networking ends at a very basic understanding of the OSI model, and I am very interested in taking a deep dive into the networking world.

>There is very little change from one iPhone to the next

Visually, sure. Under the hood? Wrong.

>The business model is built on a revolving demand cycle that is unrelated to long term thinking, maintainability, efficiency, nor sustainability.

Sorry you need to qualify this statement. An iPhone 6S is still completely usable and almost certain to be in a functional condition assuming it has been looked after correctly. That's a 8-9 year old phone. Meanwhile my 2001 phone was hopelessly outdated e-waste in 2007.

No way that any technologically competent person can claim that the iPhone 16 is a massive and amazing improvement over the iPhone 15. There is "change", sure - the chip is now every so slightly faster, it can do "AI things", it can take slightly better photos, etc. But any comparison of these changes with the previous model for an average use case - which is what most people buy iPhones for, not benchmarking - would hardly yield any visible differences. Scrolling through reddit or HN or Instagram is about the same on both devices, and gaming gives you a few more frames if you care about that sort of thing, and I say that as someone with those exact models. Apple could have easily skipped releasing a new model this year, packaged exactly the same hardware and released the iPhone 16 the next year and fundamentally nothing would've changed. But the shareholders won't like that, will they?

> a basically-similar argument in Kleene's 1967 textbook.

This textbook is an astonishing piece of work of an astonishing mathematical genius. The amount of all kinds of weird (and useful? I'm not much of a logician myself) logical stuff in it is just mind-boggling, just as its writing style. You can keep come back to this book for years and find something new in it every time.

Barendregt's book on lambda calculus is another example of such a book.

My professor in college also referred us to read Kleene's book whenever we could, but the darn thing was (and still is) so hard to find.

Looks interesting for sure and I like the syntax. Also, they seem to be using both Zig and Rust in their compiler from the looks of it?
