There was discussion on the pihole reddit about it. I'm fairly certain it's a direct competitor, there's really not much difference. There's a bit more usability with PiHole but AdGuard is also trying to make theirs very easy to use/set up. I think the issue is that AdGuard Home is trying to work on a bunch of devices which is gonna be a bitch when PiHole works well on an RPI specifically and thus is easier to make sure is working great. But then again, AdGuard is a business that does well otherwise and PiHole is a bunch of randos relying on donations.

It should be noted that, despite it's name, the pi-hole works on basically any debian-based distribution, and with a bit of work, probably any flavor of linux.

Yeah but the idea behind poo poo designed for RPi like Pi-hole (and Raspbian) is to be super minimalist and tailored specifically to the ultra-low processing capabilities of the Pi. It also means that devs don't need to give too much of a poo poo about varying hardware for end users.

The http server is optional because you can forego the web-interface entirely if you want (and issue commands to daemon via command line - eg: "pihole updateGravity"). It's also not necessary for ad's to be redirected to a valid http server - it's actually more efficient to just TCP-reset them with the following iptables rules (this assumes a lan subnet of 192.168.1.x): code:

The Ubuntu 18.10 blog post mentions expanded graphics support on RPi 3 Model B and B+: "The Linux 4.18 kernel together with updates in Mesa and X.org significantly improve game performance. Graphics support expands to AMD VegaM in the latest Intel Kabylake-G CPUs, Raspberry Pi 3 Model B, B+ and Qualcomm Snapdragon 845." So looks like it may be ahead of Raspbian which is still on Linux 4.14 as of the Oct 9 release. Does this mean Ubuntu 18.10 enables some games/applications that couldn't be run on a RPi before?

There is probably a 1-3% increase in graphics performance, not especially substantial. I think we're going to have wrung most of the performance out of the chip at this point. Probably will be stuck with the same games from now until the end of time, or at least until the raspberry pi 4/5 is released using a moderately modern could. Nvidia tegra x1 (Nintendo switch) or some allwinner (A80 ?) would be interesting, or any Qualcomm chip, especially the snapdragon 600-series would be a massive bump up. I think I saw someone claiming that the x1 was going for $40, is probably a lot cheaper now that Nintendo has bought 20 million so far, and will likely buy another 20 million. But the allwinner run $0.10-3.00

Is running an RPi (or competitor) on battery power a particularly perilous plan? I’ve been considering a portable retropi set up for a long time and think I’m gonna treat myself. SD corruption seems like the biggest threat, but most of the important files (config, saves, etc) can be stored externally.

As long as the battery has a charge it'll work fine. You can get watchdogs that will power the system off cleanly if the power supply is in danger of going dead. I haven't actually done it so can't say how easy/fun it is, but the solution is out there.

Is there a way to do that beyond having a data cable attached to a UPS? I have the apc daemon installed and that shuts down my rpi if power gets too low.

Super easy to tell the Pi to shutdown gracefully when power has been cut after X amount of time or when Y percent of battery life is left. e: accidentally a word Professor of Cats fucked around with this message at 23:46 on Oct 25, 2018 |

Amazon now sells a variety of ESP8266 and ESP32 (which sit somewhere on the spectrum between Arduino and RPi, closer to Arduino) that include an 18650 battery holder + 128x64 OLED display, and charging circuit for ~$12. With the battery you're looking at $15-20 all in. Of course, you have to compile everything from scratch, or figure out how micropython works, which is a level up from RPi.

Regarding battery powered pi - I've run pi's off of portable USB powerbanks before, they seem to last a fair while (longer than using them to charge a phone) though I found some powerbanks put out much more stable voltage than others (a phone is a relatively constant load, a pi not so much). I never did this for long enough to worry about monitoring the charge level, but if you don't mind opening up the powerbank it'd probably be pretty easy to connect one of the pi's pins to either one of the charge indicator lights or direct to a lithium cell for monitoring voltage.

Not sure whether to stick this in here or the general linux thread as I think it's more docker related than Pi specific, but here goes; I'm new to docker and only have passable linux experience. I've got docker and a few containers up and running on a RPi3 running raspbian but all the "-v /home/pi/dockerfig/:" files are created with root ownership rather than my pi user, so I'm forced to sudo edit config files in nano/vim where as I'd prefer to winscp in and edit in Notepad++ Any general thoughts on why this might be, and even better how to fix it for existing and future containers? Edit: running chown on the folder doesn't seem to have messed anything up so far. I love a simple fix. MeKeV fucked around with this message at 23:39 on Nov 5, 2018 |

Anyone have tips for debugging a suddenly unmounted sd card based root partition? I'm SSH'd into my raspberry pi, and all of a sudden, no commands work (ls, cd etc.) with error messages like "-bash: /bin/ls: No such file or directory". I can't read any log messages or use any commands as far as I can tell. I'm at a loss as to what to debug right now.

I'd just reboot it and pray. But bash builtins will still work, like "echo *" can replace ls and "echo $(< filename)" can dump a file. But those are just parlor tricks, just reboot it.

Am I just misguided or are there only a small handful of actual basic GPIO pins on the Rpi? What's the solution if you have a whole bunch of inputs / outputs?

Malloc Voidstar posted:RPi has 26 GPIO pins. So you can reprogram all of them? I was under the impression a lot of them were reserved for specialty TX / RX stuff. E: Just spitballing, 26 / 2 = 13 but minus a handful for GND and constant 5v etc, that's not that much for basic I/O (think switches and relays etc). What if I wanted to pull input from 10 switches and control 10 relays?

Then you wouldn't buy a gimmick computer with most of the relevant specs locked down 6 years ago, whose gimmick was "just make something for $35". It's not a serious GPIO platform, just a relatively cheap and relatively popular one.

You're also not going to be able to turn on a bunch of relays anyway. Depending on the relay, even one is likely to burn out a gpio pin, they're not designed to handle a bunch of current

If you want to run a relay, just put a transistor to stop the current that runs the relay and activate the transistor with the GPIO pin. Seems kind of redundant though.

Switches can be setup as a row/column grid layout like a keyboard, depending on the kind of switch you're working with. If you want a bunch of I/O there's microcontrollers more appropriate for that kind of thing like the atmega 2560: https://store.arduino.cc/usa/arduino-mega-2560-rev3

If you want lots and lots of GPIO pins just get yourself something like the MCP23017 16-channel I2C port expander. $1.25 and a bit of software and you have 16 extra IOs. Use all 127 addresses on the I2C bus and you have 2032 pins. Go nuts
