Thanks to you and @kingosticks above for digging up these official accounts. Cursory examination of rpi firmware suggests that this DRM logic is implemented in start.elf, one of the proprietary blobs required to boot an rpi. This is, in itself, significant, since opening this blob would obviously make this restriction easy to circumvent. In other words, rpi have taken design decisions which essentially motivate them…

The same could be said about the VideoCore 4 blob which was used to boot the SoC. And yet they just did get rid of it.

I don't think they got rid of the blob, so much as moved it from the SD card to an onboard SPI flash more like you'd find on a typical PC. It's still there and even more required to boot the board than on previous Pis, but people distributing images no longer have to worry about the licensing and other headaches that were caused by having to include it.

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?

Do you boot Raspbian from a SATA SSD ?

I have the same setup on 2 pis, and even on a 3b+ I've found it's easier to just put a cheap little microSD card in to hold the bootloader than to try to get USB boot working.

The Pi3b+ can boot of USB without any SD card. Can also do this on previous model https://www.raspberrypi.org/documentation/hardware/raspberry... but as you can read, that would make a permanent change to enable via a one time programmable bit and remove the ability to boot from SD card.

Though as you have the 3b+, then you have none of that dilemma and it will just boot, done it myself.

Given the fact that a single Arduino costs about half the price of an RPi... The only reason I would consider buying an Arduino (or similar) is for super-low-power applications.

Yeah, that's what it's meant for. RasPi is a computer, Arduino is a microcontroller. Different tools for different jobs.

Yeah, but my point is that Arduino has a much higher premium than a Raspberry pi.

Otherwise RPi would have been copied a long time ago at a lower price.

The RPI4 w/ 4GB RAM is going to be a very welcomed upgrade in the emulation scene. N64, PS1, Dreamcast and PSP games will run so much smoother.

Does the 4 have a composite output, or is there a hat for it? My game room has a CRT and while I'd love to stick to original hardware, the price of getting it to read games from non-original media (which is getting harder and harder to come by) is pretty high. An RPi 4 could be reasonable alternative.

Plenty of clean food in dumpsters for you to eat too.

> compact home cloud Can we just start calling them servers again?

The distinction in actual usage between using cloud, server, and homelab to describe their setup seems to be rooted in their purpose.

* Home Lab :: Running a partial/full enterprise IT stack for fun and education.

* Home Server :: Running primarily internal services like file storage, backups, media streaming, home automation, maybe some light networking.

* Home Cloud :: Running primarily external services on the public internet to replace 3rd party SaaS services. More often than not this is done with a VPS provider rather than physical hardware in your home.

So maybe you find the terminology annoying since everything is cloud these days but it's genuinely useful to us folks in the forums. You can also call "home cloud" selfhosting if you find it less jarring.

> Gigabit Ethernet! Does it have PoE? Having to deal with one less cable would be nice. Especially given that the latest spec, IEEE 802.3bt from September 2018, now allows for up to 100W per port: * https://en.wikipedia.org/wiki/Power_over_Ethernet

There is an official PoE board that fits the pi 3+ which uses a 4 pin header by the ethernet jack to grab power. The pi 4 appears to have the same header. https://www.raspberrypi.org/products/poe-hat/

I have one of these but am new to RPi. It covers all of the GPIO pins in addition to the four header pins for power. Is there any way to still use the GPIO pins with the PoE hat?

I really wish they'd release a version with dual Ethernet ports. It would make router/firewall use cases a lot easier without the need for clunky USB-ethernet adapters.
