Are you sure? I've worked with a myriad of ARM devices, and I would say that despite their small size, Hardkernel are one of the most responsive companies when I have had issues. I say that as both a Gentoo and Kali ARM dev

I'm sure, just check available OS images for their old boards.

Hardware vendors hardly are the best sources for OS images, except maybe for very new boards. When I shop for a board I always look if it is supported by community driven projects such as Armbian, DietPI or even plain Debian.

Take a look here if your board is supported.

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've been using the RPI2 as my HTPC/NAS Using the Pi as a file server can be a bit flaky. The ethernet controller was an USB one, and was neither really stable or took load very well. The new PHY on a dedicated link is probably the single biggest improvement with this new revision. The HEVC is a bit unexpected considering the high license fees and general uncertainties. Let's hope the documentation can be released…

are you speaking about the pi 4 or 2?

I just setup my RockPro64 with 4GB, also PCIex4, have an SSD, going to setup a raid at somepoint when I get it all figured out. The board was a bit more expensive than the pi4, but I am interested in playing around with it.

But it looks like its back ordered for awhile

> The addition of gigabit ethernet and USB 3.0 means that a Pi no longer feels like a bottleneck The model 3B+ already had this though.

The ethernet port on the 3B+ is still attached to the USB hub on the board. In my tests it never gets more than 300 Mbps. The Pi 4 should have true GigE support because it doesn't have that limitation.

How fast does the attached drive write though? Assuming an external spindle drive for storage.

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/

Seems kludge-y. IMHO, if one is going to do one of these types of embedded systems, then PoE should really be part of the design process from the beginning. They're using the Ethernet on the BCM2711, and Broadcom has sadly deemed PoE not needed I guess. The PoE HAT had a bunch of issues: * https://www.theregister.co.uk/2018/09/11/raspberry_pi_poe_ha...

> The PoE HAT had a bunch of issues

They released a new version quite a while ago.

I agree that it would be nice if PoE was built in, but there are better ways to say that than what you said.

Also, the HAT has a transformer (and I assume if they included it, they know what they are doing), which seems like it would be too much for every single Pi to include one.

It doesn't draw anywhere near that. 15W max (for accessories), and 7W in heavy use (without anything other than the board itself).

I just put together a Plex server with the RockPro64 4gb ram, PCI3x4 with 2 sata ports. I booted it up with Dietpi and things are running smooth!

The board is a bit more expensive, but you can probably get it faster than the pi4 at the moment.

The Dietpi community seems to be pretty great, any issues I ran into were answered pretty quickly

Excited too, but $55 + $13.95 shipping = $68.95 is inching closer to the $99 (free shipping) territory of the Jetson Nano.

Does it really compete with the Jetson Nano? I thought it was designed for AI stuff

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 th…

I installed a low-latency kernel on my desktop machine with a midi keyboard over USB, got horrible performance until I got off of Pulseaudio. I had some difficulty with Jack, but Alsa worked great. The main thing is you can't run Alsa and Jack at the same time. Once I was no longer using Pulseaudio, a lot of my problems went away -- I think it's just a really slow interface. I mostly worked off of http://www.tedfelix…

Thanks. I got the feeling there was some buffering happening somewhere, but couldn't turn it off. Wonder how much applies to Rasbian.

How is that Hat $20 when the entire board itself is only $35?

> Raspberry Pi 3 media center Just read theverge review on how the Pi struggles to play a video full screen, even if resolution is 480p. How are then people using it as a media center?

I had no issues using an RPi 3 for my media center, playing 1080p video from an external hd, but my TV is pretty cheap and barebones.
