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…

Even so, A72 is a highly-inefficient chip (which is probably why they set such a low clock speed for it). Cortex-A73 would've been much better. But I guess there always has to be at least one obvious lacking in Raspberry Pi generations.

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…

I can't read that article because Medium has decided that I have to login to do so (and possibly sign up).

Needless to say, I won't be reading that link.

Wordpress.com wouldn't have done that with your content. Just saying.

I'm using Rancher's k3s[1] on a Rock64, and it works perfectly. I maxed out the capacity recently and I was looking to add more nodes to my cluster. Looks like the new Rpi 4 would be a good addition ! [1] https://k3s.io/

I'm curious. What do you use it for?

Radarr, Sonarr, Bazarr, Plex, a small Nginx, and soon a Pi-Hole and VPN. It's a great companion for an iPad Pro, so you can also use it as a development machine when coder.com finally release an ARM docker image ! (https://github.com/cdr/code-server/issues/35)

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…

> One is running a custom Hue automation I built to shift the color temperature of the lights throughout the day. Ooooh do you have the code up somewhere for this? I would love to set it up at home :)

Hue has a Labs addon that does this. You can try that easily. Didn't work for me though.

If you have Home Assistant, someone built code for that: https://community.home-assistant.io/t/circadian-light-with-p...

As for mine, it's a total hack job, but for what it's worth: https://gist.github.com/fpgaminer/7840a6f2fb2d3a3be83625d7ac...

I don't do the fancy minute by minute adjustments to the color temperature; just a couple fixed settings for time of day and based on when the sun sets. And I just have it adjust a scene, which I have my Hue switches configured to use when I turn the lights on.

There's no good way to have this system work with, for example, turning on the lights through Alexa/Siri/etc since they won't use the Circadian scene that's been setup. But what I've got works well enough for now.

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.

If they wanted to be open they'd probably transition to RISC_V.

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 pub…

if you run a "home cloud" on a raspberry pi 2/3/4 or an orange pic or something else entirely and it fails, will your "cloud" go down with the hardware? If does go down then it's not cloud, no matter what hardware you're using. In general, my rule of thumb is: what's the upper limit, the capacity or your wallet? If the limit is the capacity, then it's HA. If the limit is your wallet, then it's cloud.

I bought an NVidia Jetson Nano 4GB memory- because I liked the Raspberry Pi so much, but the Pi 3 does not really work as a development machine. The Nano does really pretty well with the addition of a fan, swap space, a good power supply (adafruit). The BIG problem with the Nano is that it is arm64 and the availability of the Arm64 linux things (like Docker images) is limited. I ordered a 4GB Pi4 which seems to have…

That's interesting. Would be a cool use case to carry around a hi-res Chromebook for light use and plug in to a Pi or Jetson for dev work.

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)

Which CO2 sensor did you go with and how happy are you with it, if you don't mind talking about it?

Don't forget to keep it powered while it's in the drawer so you could ssh and build something really awesome. Maybe it's a personality flaw, but I get plenty of satisfaction from just reading blog write-ups if things I could have done with my tech junk, without all the associated time invested. It's much easier to vicariously enjoy projects like these, which is why I think drawer-dwelling is an inevitable destiny for…

My flaw regarding SBCs, is that I want to master the whole stack (what variant of linux.. , how is is written,...), yet I don't have the context to, so I get fed up with almost good use cases and lose interest. That's also why I'm tring microcontrollers, it's back to low level, less shiny projects, but mentally saner.

Any suggestions on microcontrollers? I love my pi but I've been wanting to try my hand at something a little less, desktop-like.

I wish they'd integrate PoE (without the hat). That chip they're using appears to support it. http://www.trxcom.com/Product/product/id/353.html

I guess they needed to drop that and a lot more to hit $35 price target.

The poe hat costs $25 USD so it makes sense they needed to drop it
