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)

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.

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 imagine the wait must be agonizing! Why not just have a NFS server on your more powerful computer for the Pi to stream the file from? 100 Mbps is easily enough to stream any Bluray.

Not at all. The reason I upgraded my home LAN many years ago was exactly because 100Mbps is not enough to stream 1080p videos.

It does suffice on average, but the bitrate changes a lot within the same file.

That's pretty clever. You should marry her.

Have you tried surfing the web on a Raspberry Pi 3? Even if the 4 is 3 times faster, it’ll be a frustrating experience. Additionally, once you add in all the peripherals for a laptop, the cost is much higher than if you just bought a cheap netbook. 4GB of Ram Pi 4 is $55. $30 for a decent USB C power supply and cord, plus $50 for a display, $15 for keyboard, $15 for mouse, plus $15 for a decent SD card and/or hard dr…

Have you tried web surfing on a low end but modern dual core Intel laptop? It is painful as well. I didn't realize how bad it was until I tried my wife's Best Buy special instead of my supped up dev machine. The average low end device you get at Best Buy is barely usable. You at to at least go up to mid-range to have it not suck.

You are right about Intel but not x86. Get an AMD APU 2400g.

The Raspberry Pi Foundation is a nonprofit.

How are you a non-profit if you pay a salary to you employees and allow your suppliers to make a profit?. They act as a 'low profit' company, but they do make profits.

Are there any single Widely known, Non-Profits Organisation that fits your description?

IIUC, you're saying that, for the Raspberry Pi designers, being open hardware is not only not a requirement, but there's actually requirements to be aggressively closed hardware in some regards?

I don't think one can paint attempting to stop counterfeit cameras (which were aggressively counterfeited) as being aggressively closed hardware. Look Rpi have a clear goal, to get kids coding. Everything, and I mean _everything_ they do is to further that goal. One part of that is to have a platform that is, safe, easy, expandable and _cheap_. A side effect of that is that its mostly open. Now, is it as open as say…

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 only a small set of particular cards could be used, which was very unusual for PC hardware based on open standards. One of the biggest practical reasons to put Coreboot on those ThinkPads is to get rid of the awful whitelisting, so that people could use whatever cards they wanted, including using WiFi cards supporting later standards and working without having to download closed firmware blobs.)

I looked at the dmesg from someones Phoronix testsuite run and it has: [drm] Initialized v3d 1.0.0 20180419 for fec00000.v3d on minor 0 So this is vc5/6, not vc4. Additionally: Vendor: Broadcom (0x14e4) Device: V3D 4.2 (0xffffffff)

Do we know for sure that all VC5/6 SoCs support HDR decoding, or is that still unknown? The Wikipedia page for VideoCore only lists one VC5 SoC and no VC6 SoCs. The Broadcom page for the VC5 SoC is pretty uninformative.

The KMS in this new chip is still the old VC4 HVS (high-speed video scaler). That chip can not output any 10 bit formats.

(But it also wasn't capable of 4k60, so maybe there are some modifications there.)

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

Given the fact that a single Arduino costs about half the price of an RPi... The only reason I would consider buying an Arduino (or similar) is for super-low-power applications.

Yeah, that's what it's meant for. RasPi is a computer, Arduino is a microcontroller. Different tools for different jobs.

Gigabit Ethernet? I'm tempted to grab a few and try running Pi-Hole for my whole organization (~1200 users) and see how that goes. :) I know you can set up Pi-Hole on Ubuntu VMs. But there's something so attractive to me about running it separate from your hypervisors and closer to the core switch on very very cheap hardware.... Been curious about Pi-Hole on my bigger work scale for a while, this may very well tip me…

This seems like it could start replacing cheap firewall hardware. I believe pfsense no longer requires aes-ni (?), so it seems like a good choice for that.
