For those of you with a local Microcenter, the Raspberry Pi Zero Ws is on sale for $3.14 in honor of Pi day. Limit 1 per customer, but didn't give me any grief for buying one on Saturday and one on Sunday, or for bringing my girlfriend both times so she could buy one as well.

So I'm running into an issue that I'm not 100% sure what the root cause is. I am trying to NFS mount my FreeNAS to my pi, and I made a directorycode:code:

I couldn’t resist stopping in to buy yet another ZeroW for $3.14 They used to just keep them in a fishbowl. Now you have to ask a manager who escorted me to the register. It’s $3 dude.

Looking for an sd card for the pi, 128gb. Most of the cards I'm seeing are ~$40 on Amazon, but then there's the Sandisk Extreme card for $65 and then a couple cards that look to just be upsold. For that capacity, is ~$40,45 what I should expect for a quality card that doesn't have complete poo poo speeds?

Sandisk is the can't go wrong brand. $45 for 128gb seems low to me, what speed class are they?

Yes, SD card specifications are a loving disaster. Fortunately the specification group has a handy chart, which literally no one can remember and ends up googling every time they want to buy SD. https://www.sdcard.org/developers/overview/speed_class/

I almost bought one the other day when I saw the price, but then I realized I already have a zero and two zero ws I'm not doing anything with so I don't need any more. They also now have a "Zero WH" which has the pinheader preinstalled, but they want like $13 for it and gently caress that.

For that capacity, is ~$40,45 what I should expect for a quality card that doesn't have complete poo poo speeds? The Pi cannot use the speeds that superfast SD cards provide, because it's all hanging off a USB 2.0-limited interface. The most important thing faster cards can still provide is marginal improvement in IOPS and random read/write, but that's not usually worth the price premium. Essentially you want to at least get a card that can provide 20 megabyte per second read and write for continuous read and write, but anything over 30 megabyte continuous read/write is going to be something you're unlikely to use due to the interface. And checking for the random read/write speeds is usually a waste of time cuz it isn't usually listed, so you need to just find some random guy who's used the card in question to see if they can or have tested that for you. It is of course nice, when you're transferring content onto a card, to have as fast a card as possible because a PC with a proper usb 3.0 based reader on it can take advantage of that to like load on a whole bunch of games or music real quick. But since you're not going to do that all that often it's not going to be worth dropping another like $20+ just for that, you know? fishmech fucked around with this message at 03:12 on Mar 14, 2018 |

Yeah true, but amazon's product descriptions have grown into moldy poo poo over the past few years so that's not really a surprise. I was linking it more so you could squint at the logos on the product itself. My MO for SD cards is to buy whatever sandisk is selling for $50.

PoE is really interesting, and adding a gigabit ethernet port, even if it will max out the USB2.0 speeds, is at least an improvement. I dunno that I'd pick one of these up, even though its a pretty solid refinement or wait for a full fledged Pi4.

Built-in PoE is my biggest want out of a Pi4, but the fact that their hat seems to require active cooling, probably means that’s not happening.

The price of the PoE hat determines how much I care about this. Improved network performance might be nice in a few situations, but the fact that it's shared with USB still makes it hard because most of the applications I have that need bandwidth would be using it to stream data from a USB peripheral. PoE on the other hand would be very nice for a lot of my uses, as long as it's cheaper than just using an external splitter dongle.

xzzy posted:Biggest issue with the pi getting poe is it means I need to replace my router with one that has poe making a $35 purchase at least $100. If you just need a few ports and maybe some basic management features I'm becoming a big fan of these: https://www.amazon.com/TP-Link-Gigabit-Ethernet-Desktop-TL-SG1008P/dp/B00BP0SSAS Pretty cheap, even cheaper if you buy through an Amazon Business account for some reason, and they work reliably unlike their Netgear counterparts. If you want more ports, I like the UniFi products because their management is really nice compared to other lower end switches (where lower end is defined as switches intended to be managed through a web interface rather than a CLI).

I know both Ubiquiti and Mikrotik have products that do this, mostly aimed at the WISP market so the router in the building can power the wireless bridge up on the roof/tower (Ubiquiti also uses this for their GPON ONTs), but I've never really used them because every place I've used PoE has been on the LAN side in a facility large enough to need a separate switch anyways.

Yeah, it's just geeking out. I have a shelf in my basement where my internet comes into the house and my WiFi and Pihole are hanging off the router. Power them both with poe and I could get rid of two wall warts! Mega efficient!

Ah, then yeah it looks like your cheapest option would be this one: https://mikrotik.com/product/RB960PGS Not too bad actually, price wise. There are cheaper variants but they only do passive PoE rather than af/at. I might have to get one of these in and test it out, for $80 it could be very nice in certain environments.

Really looking forward to the day when they pick a new chip architecture and USB-C. They've gotten a lot of use out of broadcom over the years but Arm v7 compilation support is really good these days and not much reason to stick with it at this point.

Their biggest issues really are "no GPU improvements since the very first pi" and "still using a USB system bus. Ideally we can get it set up so the GPU can be semi modern, a normal system bus used for most things standard, and then proper USB c 3.1 support

The system bus is axi. Thus they are stuck with Broadcom and Broadcom hasn't made a new soc yet with non poo poo peripherals since what set top box needs usb 3.0?

They got cheap rear end chips and are now paying for them years down the road. The rpi is also a smashing success. I own 2 and they are fine. It's just not good for streaming 4k or intense compute work but I have other hw for that.

If you want lots of power in a small box, get a NUC or something. If you want to gently caress around with servos or cameras or any other goofy electronics project you can think up, get a pi. The pi is amazing for what it is, not sure why people want it to be a super computer.

You can get an odroid that’s basically the same form factor except 10 bucks more and vastly more competent. If they produced at the scales RPi does it’d be even less.
