Does anybody know if the ethernet controller supports PXE boot?

Network booting is supported. I don't know if the architecture is similar enough to the x86 bios loading network card option roms that one could say the "ethernet controller supports" it. Booting on ARM is different.

Oh my! This is such a crazy upgrade. I've been using the RPI2 as my HTPC/NAS at my folks, and I'm so happy with it. I was itching to get the last one for myself. USB 3.0! Gigabit Ethernet! WiFi 802.11ac, BT 5.0, 4GB RAM! 4K! $55 at most?! What the!? How the??! I know I'm not maintaining decorum at Hacker News, but I am SO mighty, MIGHTY excited! I'm setting up a VPN to hook this (when I get it) to my VPS and then do…

I have a 10tb external hooked to my routers usb 2 port and have always been looking for something better. This looks like it.

Earlier quoted context omitted.

As a previous line manager one said to me “yes, and I want a pony”. That they want to be more open does not mean they are currently fully open – in fact, it requires them to not yet to be fully open. Their primary goal (last I checked) is to be cheap, being fully open is at the very best their secondary goal.

That doesn't follow. Firstly, I don't think I've seen any other SBC vendor fail to publish full schematics. This is a peculiarity of rpi's offering. Secondly, nobody is forcing them to add DRM chips to anything. That's not something that can be written off on "a contractual obligation made me do it." They did it of their own will.

Counter hypothesis because I can’t be bothered to research it fully:

Pi: “Hello we wish to buy a $thing”

Vendor: “Certainly. We sell $thing for ten dollars per unit if it doesn’t have DRM, or five dollars per unit if it does.”

My first reaction to the specs: Pros: + USB 3: Very nice! Finally a pocket-sized, fast USB host. + Dual HDMI: Could be useful as a projector computer. + 1.5 GHz: Good, it might be fast enough for some real work. + Gigabit Ethernet: Excellent for those using it as a NAS. + USB-C for power: Not surprising, it's the standard now. Cons: - MicroHDMI: Incompatible with the 800x480 HDMI 3.5" screen [1]. Also different again…

Just need a bigger battery. 15W is achievable. You'll add more weight obviously but you get the extras of the pi4. Tradeoff. As for the screen you pointed to, isn't an adapter available?

Yes, there are adaptors, but it won't fit with the same loopback HDMI board that's included with the screen. It'll need a wire, which effectively doubles the space it'll take up on a desk.

If there are any other high-res small (<= 4") screens, please let me know - the highest DPI that I know is an iPhone 4S 960x640 3.5" screen with a Creotech adaptor.

I’m not very familiar with the hardware here but could someone elaborate on why this seems to be such a big deal that there are four versions of the announcement trending on the first page?

They remove all the bottleneck from the previous generations making it more interesting for networking and desktop use.

All? What about that nasty SD card?

No normal sized HDMI sucks, I don't want to buy another adapter, aside from that this looks really cool, can't wait to get one

C'mon, a mini-hdmi hdmi cable is 50kr ($5), surely you can just buy one and be done with it, no adapter needed. https://www.netonnet.se/art/ljud-och-bild/kablar/hdmi-kablar...

Con for me is still SD storage :-( At least now an SSD over USB3 should be reasonably fast

How about a RAMDisk? https://hackaday.com/2019/04/08/give-your-raspberry-pi-sd-ca...

certainly a good idea for stuff / locations that have regular writes, just be nice to use a more durable boot disk, hopefully booting via USB storage is well supported

>Are you still using VideoCore? >Yes. VideoCore 3D is the only publicly documented 3D graphics core for ARM‑based SoCs, and we want to make Raspberry Pi more open over time, not less. This stated intention and rpi.org's actions are simply not isomorphic. If they want to make Raspberry Pi more open, firstly, why do they publish only abridged (read: fake) schematics? [1] Secondly, why was rpi.org caught adding DRM chip…

1) They make a low cost computer where they've put significant work into making it more open software wise. Their revenue stream is through the sale of their hardware, why do they need to allow people to make clones? 2) Maybe it's to do with the terms in which they get the camera module? I don't know but I don't see them selling the camera as interoperable. Your comment just seems to exemplify the phrase: "No good de…

"freeloaders just turn up and demand more."

If this were software, this would be a discussion about open source, would you accuse people of forking an open source project of being freeloaders?
