The latest model in top drawer computing!
I'll definitely get one though. Good specs.

#242The full specs and benchmark link: https://www.raspberrypi.org/magpi/raspberry-pi-4-specs-bench...
Missing: SD card performance benchmark. Previous models could only read about 20 MB/s or so, while the modern SD cards can do 10x (maybe even more) that. Is there any improvement in this? It's pretty important as RPi usually boots off it.
In the video here https://www.raspberrypi.org/magpi/raspberry-pi-4-specs-bench... they said they doubled the SD card performance.

Yes, given the recent discussions how some projects were surprised that many companies are putting non-copyleft licenses to good use of their investors, when they are full compliant with what the license requires from them.
If that's what the license allows that's perfectly fine.
I believe the point was that some people don't think that view point is fine. No one has yet taken ownership of that position apart from possibly the great grandparent

Yes, but you're running off a sloooow sd card which may slow you down a bit if you compile stuff. Other than that it's just a normal linux computer. Mind, I've only done command line and text mode editors, if you want the full desktop and a ram hungry IDE it's going to hurt more.
Another important thing to mention: if you're compiling and logging to the sd card, buy a lot of them because they'll die on you. They're not designed for this many writes.
Why bother with obsolete SD cards then? Here is an SSD for 15€ [0]. Pair it with a 5€ USB to SATA adapter and you're ready to go.

You can boot off a USB drive.
IIRC bootloader and kernel have to be on SD card so you always boot from there but can easily pivot to the USB drive for the root partition.
Not any more! As of the Pi3 you can even netboot! https://www.raspberrypi.org/documentation/hardware/raspberry...

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.
Counter hypothesis because I can’t be bothered to research it fully: Pi: “Hello we wish to buy a $thing” Vendor: “Certainly. We sell $thing for ten dollars per unit if it doesn’t have DRM, or five dollars per unit if it does.”
Not remotely how that works.
Firstly because the rpi foundation is the one manufacturing the camera units. They are buying parts from vendors, not assembled units.
The more components you use, the more expensive a product is to make. They also don't just have DRM chips inseparably piggybacked onto things like CMOS camera sensors.

My understanding is that they mean open in software not hardware.
This doesn't add up either, since they seem to be effectively walling themselves into not opening up some of the software needed to boot rpis, which remains proprietary. See https://news.ycombinator.com/item?id=20261549
The assumption that they would prefer to handicap their main product because of some unknown deal they have on an accessory seems biased to me. The SoCs that they use are Broadcomm ones, a company known for being hostile to open source. Perhaps the fact that they have now sold over 25 million units of what is essentially their old designs that wheren't selling anymore is opening their eyes on the money that can be made. The developer of the new open source gpu driver is a Broadcomm employee.
The point is that for some unknown to us reason they deemed it a good idea to add DRM on a side-project they have. But that doesn't mean they can't make a new camera at some point.

#249>Are you still using VideoCore? >Yes. VideoCore 3D is the only publicly documented 3D graphics core for ARM‑based SoCs, and we want to make Raspberry Pi more open over time, not less. This stated intention and rpi.org's actions are simply not isomorphic. If they want to make Raspberry Pi more open, firstly, why do they publish only abridged (read: fake) schematics? [1] Secondly, why was rpi.org caught adding DRM chip…
My understanding is that they mean open in software not hardware.
That's a bit misleading given the hardware is kind of the selling point here.
