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…

Feels like an exponential upgrade.

I agree with your excitement! I've been waiting for this upgrade forever. I keep looking at the other options out there, but while their hardware is great, their software is terrible.

Can't wait to buy this, boot it up, play with it for four hours, then stick it in the same desk drawer with the other Pis I have bought over the years. (The upgrades look great, just my attention span is not so great)

That's silly. RasPis are stupidly useful. I've got: * A Zero W hooked up to a PM2.5 to do air quality monitoring in the house. Just bought a couple more sensors for it (VOC, eCO2, etc), but haven't hooked them up yet. * A 3B+ running the UniFi controller for my home network. * One is running a custom Hue automation I built to shift the color temperature of the lights throughout the day. * One is built into an interne…

Ooooh do you have the code up somewhere for this? I would love to set it up at home :)

I'm super excited as well. I figured out the secret sauce to get a low latency kernel build I was able to get down to 20ms latency but I'm excited to see if this can't get down to 10ms even though 20ms is acceptable low audio latency, already with only 1 gig of ram on a pi3 ardour is usable for multitrack recording, excited to see how this does with 4 gigs.

I recently connected a midi keyboard to our Pi3 and ran Timidity for synthesis. It worked, but unfortunately the notes happen about half a second after you press a key, making it rather useless. Strange, since if you dump the midi events themselves to the console they appear to happen immediately.

I tried teaking alsa and pulseaudio settings, no luck. Also installed jack but never got sound from it. Eight hours on the weekend wasted with nothing to show for it. Any ideas on how to fix this?

Earlier quoted context omitted.

IIRC bootloader and kernel have to be on SD card so you always boot from there but can easily pivot to the USB drive for the root partition.

Nope, it can boot from USB without SD card.

Correction: it seems like RPi4 doesn't boot from USB or Ethernet yet; they will release a firmware update to turn it on.

"Support for these additional bootmodes will be added in the future via optional bootloader updates. The current schedule is to release PXE boot first, then USB boot."

It's fine if that's their requirements, but that wasn't clear originally. It seems that people who care about technology open standards, open source, and open hardware need a clear understanding of Raspberry Pi requirements, and that they're actually getting hardware that is more closed than a typical PC. (Related: Starting over a decade ago, some IBM ThinkPad models infamously whitelisted mini-PCIe cards, so that on…

It was always the requirement. It was designed as a machine to replace the BBC micro. most PCs have BIOS, which is closed source, and difficult to get access to. yes there are opensource alternatives, but they are not entirely practical. Most modern PCs have a TPM, EFI and a whole host of other bits that make opensource drivers exceedingly difficult. Then there is the graphics card, where if you want to actually have…

Although PCs have traditionally had closed-source firmware, this firmware has not typically been used to implement malicious functionality (aside from cases such as the Thinkpad example above), making it historically less of a concern (though this is changing). Vendor lockin doesn't magically become acceptable because kids (nor is it ethical to teach kids that DRM is okay/normal).

Also, define rpi clone - rpi did not invent the SBC genre. Many more open products precede it.

FYI, AMD graphics drivers are fully open now.

That's great, but if you need crypto (because you have LUKS storage and send AES encrypted data over the network, like in a usual NAS case), A53 with aes instructions may be faster than this A72 without one. And so far it seems these cores don't have aes instructions.

Maybe. It has a lot of CPU power relative to IO bandwidth, it should do ok in pure software. Hmm, anyone know if the VideoCore VI would be any good for crypto?

Quick Googling [0] revealed VideoCore VI might have at least some support for Vulkan and/or OpenCL. If this turns out to be true, then yes, VideoCore VI might be able to function as a crypto-coprocessor.

We'll see.

Depending on the purpose, for example if somebody just wants a compact home cloud, the Odroid HC2 could also - still - be considered: https://www.hardkernel.com/shop/odroid-hc2-home-cloud-two/ - Half the RAM but double the cores. I'm waiting for some benchmarks to see if the RPi4 is faster and by how much. - Also Gigabit Ethernet and it works great. My downloads are always at 108-111MB/s for the whole transfer. - Not…

This thing can easily replace my laptop.

For the 4GB model, my very usable if somewhat low-end IBM Thinkpad ~15yrs ago had about 1/10 as much memory. Probably similar on the processor—I bet one core on this is something like 3x as fast as the single-core Celeron I had in that thing. Video capabilities are so much better it'd be hard to even compare them. IO's much faster—5400RPM spinning rust on that laptop, the SDCard's probably a lot faster even, let alone the USB3. The only reason this thing might not make an excellent desktop these days is all the bloated web shit we use.

What's the unifi controller?
