Pis find illegal images

https://www.bbc.com/news/technology-44525358

An Austrian wrote a system to locate and delete illegal images, based around 3 Pis and some neural net hardware. Total cost: about $300.

Re: Time keeping and accuracy

And, just to cover all the bases, if your Pi *doesn't* have an internet connection (or there is filtering on the connection that blocks access to NTP servers), you can add a Real Time Clock (RTC) module to your Pi.

You might take a look at gimp. If that's too complex, see what LibreOffice can do with it, as it has some image manipulation features.

Re: Power for stacking Pi's

Re: raspberry pi display

I don't buy new monitors for Pis, they cost several times what a Pi does. Things to look for in a monitor for a Pi: 1. HDMI or DVI input (this is the really important item). 2. A size you like. 3. An aspect ratio you like. Ways to get an inexpensive monitor: 1. Any unused monitors you happen to have...

Re: A newb's two problems

The Pi *should* get the monitor geometry from the EDID data. If you have a black border around the desktop, all you need to do is uncomment (that is, remove the '#' and any spaces from the beginning) the line "disable_overscan=1". This can also be done using the desktop comfiguration utility (which ...

You might be able to a equivalent if you hunt around. The RPF PSU cable is fixed to the unit though a molded strain relief. It's not a separate cable.

Re: Cheap Networking

The RJ45 connector has components inside the shell that must be present. You cannot direct wire the Ethernet from board to board. A proper CAT5/6 cable must be used.

Probably best to ask the people who actually wrote that paragraph.
That they mention about the hardware limitations present on RPi3 itself made me ask the question here.
That the Pi first boots the VC4, not the ARM CPUs might have something to do with it.

So long as they're still in the powerbank, probably. I'd be rather more certain of that if the actual output specifications were given (and were suitable). I'm basing the "probably" on the assumption that the output is 5v. I wouldn't recommend disassembling a powerbank unless you are experienced at ...

And just to close the loop on all this, the '|' symbol is an 'or' to some program languages, but in writing commands to be processed by bash it is, as stated "pipe", which means that it takes the output from one process and sends it as input to another process. No logical operations are performed on...

And, no, there is no Pi with an "on board" power switch, though the WD SATA Adapter board for the CM/CM3/CM3L does have one.

Re: Power for stacking Pi's

I read you correctly, you want to wire the Pis in parallel to a common PSU. (I'm hoping I didn't mis-read and you really want to wire them in series because that would require the first Pi to have enough current for all subsequent Pis running through the board and that would--potentially--be nearly ...
