I don't use even one HDMI on RPI why second? Also, it's fricking micro-HDMI why not another TYPE-C?

Type-C are expensive, it's worth the extra cost for the power stability (bad power is what causes most of the problems with previous Pis) but would increase the price if they used them for displays too.

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…

Hmm, I've been using a Pi 3B as a router for ~6 months with no issues like that. I wonder if these were resolved at some point?

I'm wondering if you could power two USB 3.0 2.5" HDD through the Raspberry Pi 4 without requiring external power supplies for them now.

Would be nice to build a NAS with as few cables as possible.

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.

STM32s have great Rust support[0] if that matters to you. Personally I strongly prefer the embedded_hal[1] and RTFM[2] APIs over the Arduino ones, although the peripheral coverage is a fair bit weaker. Their DISCOVERY kits[3] (preassembled boards that are ready to program, just like Arduinos) are ~$20, and also double as programmers if you eventually end up designing your own boards.

What review did you read? Playing video is likely the only thing the PI 3 does really well; even most H265 FHD do play without stuttering on the 3+ although we're close to the board limits. Are you sure the writer didn't use the board the wrong way? Some people still believe that videos should be streamed after being transcoded because that is the only way to watch them on their ridiculously limited smart TV which la…

It wasn't The Verge that originally said the Pi4 struggled to play YouTube videos [1], it was Tom's Hardware [2]. Tom’s Hardware’s review notes that the hardware is able to handle many everyday tasks such as web browsing with up to 15 Chromium tabs, light image editing using GIMP, and document and spreadsheet work using LibreOffice. Unsurprisingly, the sub-$100 miniature PC has its limits. It reportedly struggles wit…

My slightly older Intel NUC struggled hard with YouTube too, until I installed the extension that forces YouTube to serve me h264 content rather than vp9. After that it has been butter smooth.

The OrangePi 3 at $40 is also pretty neat, PCIe 1x, 8GB onboard eMMC, 4x USB 3.0, Bluetooth 5, Wireless AC (pretty sure they beat Raspberry Pi to the punch on this...) and it has mainline kernel support: http://www.orangepi.org/Orange%20Pi%203/

A53 SoC, new RPi4 with A72 is going to run circles around this one.

Unless you are doing disk io and most of your CPU cycles spent on it.

An alternative would have been a powered USB hub.

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…

> * 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. We have neighbors that smoke, and sometimes based upon wind patterns it blows into our yard. Any idea if they have sensors that can pick up this sort of thing so I can close our windows?

Next step. Have the pi auto close your windows

The addition of gigabit ethernet and USB 3.0 means that a Pi no longer feels like a bottleneck in one’s home network. I know that the Pi was invented as an educational product, but thanks to the Linux distribution OSMC it is commonly used as a media center for playing films, music, TV, etc. I have had gigabit internet for a few years now, and every day on average, I torrent a Blu-Ray image onto my main computer. Howe…

> I have had gigabit internet for a few years now

Keep in mind that you are in a very small world there... most people alive today will never have internet that fast, personally i've never had a connection above 6 Mbits in the middle of a city, and I know that's likely above the median globally (keep in mind average is a poor metric due to connections like yours, SDL is still the primary type of endpoint for homes)

My point being, the previous generations USB based ethernet still has massive headroom for the vast majority of peoples internet.

I wish pi-hole was just a tiny bit more polished. I found it takes a lot of work (and knowledge of linux networking) to get up and running properly and stable.

I've run into the same. It often would come back from a reboot without DNS restarted correctly. I never went through a Pi Hole update without having to manually fix things either. A few weeks ago I switched to Ad Guard Home. Has been rock solid since. The big dancehaus it doesn't support the exact same filter files.

Yeah - I found it ironic that out of the box I couldn't get a pi-hole to do DNS lookups. It always took manual fixing.
