So is this the reason behind the absolutely piss-poor availability of the Pi Zero? Almost three months after launch they are still almost impossible to find.

They sold them all, then up until middle of January were making new Zeros and then switched to making rpi3s.

They don't need to compile anything. They just need to update their repos to point at 64 bit (it's all already built) and rebuild the image. virt-install can probably do this in 25 minutes.
As there is no official 64bit kernel they only need to update firmware and drivers.

Okay dumb question.... where are the antennas? There isn't even the cheaper on-pcb one, so I assume we'll have to buy a header/antenna/something to make that wifi/BT actually usable?

The sad thing about the 4 is that it still does not have the crypto extensions. So no accelerated Syncthing.

thanks, ordered one of these!

Played with the new rPi a bit and the performance is good as expected, easily saturates gigabit without encryption, syncthing over LAN to an encrypted USB 3 drive is ~400 Mbit, SMB ~650 Mbit. Pretty decent considering it has to do everything in software.

What is the Syncthing hashrate reported in syncthing.log? It's the lines:
Single thread SHA256 performance is ... using minio/sha256-simd (... using crypto/sha256).
Hashing performance is ...

That's about Intel atom/AMD Kabini level. 4 times faster than Raspberry pi 2. And ten times slower than Rock64 with crypto extensions.

I forget the command, I think you basically have to edit the boot config on a MicroSD card, then once you boot it stays so you can remove the card and plug in the USB. I'm positive the 3B+ is preset that way.

Some raspberrys can boot even without sd card (rpi4 is getting support some time later, brobably next year) but you can follow this: https://www.raspberrypi.org/forums/viewtopic.php?t=44177 (works for all raspberrys)

That way you can use smallest/cheapest sd card (for example 1gb) to boot. And the only time writes to it happen is kernel updates.

There are some other A72 options as well, like the ROCKPro64, but it's still a fairly old microarch. It's at least not that expensive though and it's more appealing than an ARMv7 option.

e2: actually the regular raspberry pi 4 model b has A72 cores on it as well, duh :doh:


Odroid N2 has A73.
ROCKPro64 has A72 with Crypto extensions. Rapsberry pi 4 doesn't have those.

Is there a list anywhere of external 2.5 inch USB hard drives that can definitely be used, unpowered, with later-model Raspberry Pis (e.g. 3B+; 4)? It's weirdly hard to find a definite answer to whether a given model will work - all I ever see is guesswork and speculation.

At least on pi4 (if you are using the official or comparable powerbrick) all of them.

Question: What's the next step up from a raspberry pi that is more powerful and can use a 2.5" ssd? A NUC? Most NUCs are a bit of a big jump in price from a pi.

At this point Raspberry 4 is among the fastest ones (CPU side) in the below 100$. RockPro64 might be faster and has crypto extensions enabled. All other ARM based ones are slower or much more expensive.

What would be the benefit of 64 bit for the typical use cases for a pi? It'd be great to have it but I'm not surprised it's not a priority for them.

Unlike your standard intel and amd processors where 64bit was mainly for more memory, on ARM 64bit brought new instructions and improved performance.

So apparently starting with the pi.... 2? 3? Probably 3 it's possible to boot the pi from USB

How does this impact the pre-4 pi as a functional file server? I believe most of the bottleneck lies with the network sitting on the usb bus, but I think the sd card had some negative consequences as well
SD card is was not a bottleneck for performance. But many writes to the wrong SD cards led to corruption of the cards. For that reason I have been running Raspbian from an USB hdd since pi1.

This might not be something I can do on a Pi (or at all) but I figured y'all would be the best people to ask. I'm looking to scan a bunch of my older books and turn them into ebooks, and it seems like the easiest/cheapest way to do that is to scan each page individually, then convert the img files into PDF, pull the text from said PDF, merge all the PDF files into one big one, then convert it to an epub file. So while none of that is hard, it is tedious and time consuming. So I was wondering if there was a way to automate that somehow with the Pi. I don't mind scanning all the pages, but I'd like to automate the rest of it if I could. Or if there's an easier way, let me know. I know I could buy like a 600$ book scanner, but I am not trying to spend too much money on this.

First i'd suggest researching if there already are ebook versions on :filez:. If not then feeding the images to Finereader or something like that.

Dumb help me use google question: I want an SD card reader on my rpi, which is easy, there's billions of USB options out there. But I want one that has that nice spring loaded push to lock/unlock feature and I'm not sure what that function is actually called.

If it matters, I'm gonna be stripping it out of its case and mounting it in a custom case along with the pi. So if there's a maker version of one of these that would be sweet.

Boot from USB and use the built in one.

If I were in charge I'd have gone with a standard HDMI port for monitor 1 and then had monitor 2 supported through the USB-C port with a dongle. That offers the most compatibility with existing installations while supporting all the same capabilities.

I think that c port on pi4 is only usb2. The boards are built around the Set Top Box SOC Broadcom gives them.

This can cause very unpredictable behavior with at least Windows clients where they can decide to switch over to the secondary based on a single slow response and they will stick there for a period of time meaning that you lose whatever your Pi-Hole or other special DNS configuration was providing.

Depending on your requirements, you may be able to pick up a raspberry pi 400 for $99 and shipping. It's a 4GB rpi 4 (more or less) with a built in keyboard.

It also has the better revision of chip (higher frequency) iirc new batches of regular rpi4 also have that. And a sizeable heatsink.

I'd like to access my pi from my desktop, but I am worried about security. If I enables SSH, is my pi available on the internet or only on LAN? Is it certain that I need to take extra stops to enable access from the internet? I'd only want to access it on lan for the security benefits.

I haven't been able to find answer on google.

For some time the default OS disables password based SSH by default. Only key based is available (you can't brute force or guess that.). Also if your raspberry is behind a router you explicitly need to forward the ssh port. So by default its safe.

Even on the rpi1 you can move the system to an usb stick/drive. And use the sd only to kickstart boot.
