I'm cannot determine if the HEVC hardware decoding is full 10bit or only 8bit. A lot of SDR content is encoded in 10 bit for the space savings (or so I've read).

I asked about this here: https://news.ycombinator.com/item?id=20261086

According to the response I've gotten so far, it will not support HDR or 10 bit. :-( However, the vast majority of SDR content is 8 bit. The few exceptions are mostly a few pirate groups who mostly encode anime.

Edit: this is apparently now in doubt.

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…

The model 3B+ already had this though.

Depends on what you are doing.

Local golang work with docker but mostly as a dumb terminal interfacing with a remote k8s cluster and using the web as a reference.

Can I build and run golang programs natively, or do I need to run them in docker?

(I'm new to all this, also unclear on the "dumb terminal interfacing" scenario... is that specific to using Kubernetes?)

1) They make a low cost computer where they've put significant work into making it more open software wise. Their revenue stream is through the sale of their hardware, why do they need to allow people to make clones? 2) Maybe it's to do with the terms in which they get the camera module? I don't know but I don't see them selling the camera as interoperable. Your comment just seems to exemplify the phrase: "No good de…

Other SBC makers don't have an issue offering full schematics, yet, due to their smaller size, have relatively more to lose from being cloned. Moreover, I hope nobody believes that a lack of full schematics is going to stop people from making clones. Schematics can be reversed with not too much effort. Due to their large audience and brand recognition, rpi actually has less to fear from clones than smaller SBC vendor…

I would buy cheaper RPi clones the same way I do with Arduino clones from China.

You can buy a pretty powerful full computer (networking, video, RAM, etc) that fits on a tiny card for $35. That makes it possible to build all sorts of fun things on next to zero budget - everything from robots to video game emulation systems and tv streaming boxes. The previous 3 versions were already wildly popular, but there were starting to show their age and to be significantly outperformed by Nvidia's Jetson N…

I always feel like I'm missing something. I don't have a single idea where something like this could be useful. Maybe because I don't care about "fun" projects and live a quit minimalistic live style? I must don't have (small) problems with no solutions. Then again, I've also never had an idea for an interesting software side project.

Another way to think about this is that it's the antidote to seamless portless iGlass slabs for $1000. You've got compute, a pile of mainstream ports and wireless interfaces, GPIO pins and an established ecosystem, all for basically no money. It's an open enough platform that kids, adults, startups, schools, and companies have found endless uses for them, ranging from toy projects for learning purposes to production use in for-profit settings. It's a radically different vision of computing vs. the iStore, and one that deeply appeals to all the hackers and makers out there. It's not a product as much as it's a raw material.

Too bad the USB-C slot is only used for supplying power instead of being a proper Thunderbolt slot with support for acting as a USB device or attaching external PCIe cards. But well, that's a thing for the 4+ then I guess...

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.

Has anyone set up a Kubernetes cluster using several RPIs? How did it go? Got any recommendations for distributions, tools, etc.?
