Here is a post about A2 cards on pi:

I am careful enough that I have never accidentally destroyed a disk (yet) even though I have been using dd for a decade now for everything. I was warned that it is called "destroyer of disks". However, as far as I know, there are free disk recovery tools like testdisk. This might help if you destroy...

One alternative solution is to use zram or zswap , which will compress the swap to RAM. In case you want to avoid ware to memory card, or the card is slow. OF course, the compression is going utilize cpu time, but this might be a good trade-off for some use cases. But back to topic: There is definit...

Hi guys, finally I discovered were the problem was. My router is doing bottleneck. It has 100mb/s transfer so having transfers speeds of 12Mb/s is actually good. I need to buy a router that provides 1 gigabit. The ironic thing is that fist answer to you in this thread, suggested exactly that proble...

True. But there's nothing to stop you using both, and last I looked DLNA didn't provide a way to upload new content to the server. And miniDLNA was a huge resource hog with a large library, so much so that it cause my 4B to become completely unresponsive. Interesting, I have run it off a rpi zero f...

I know that Adafruit makes a 1.8" 18-bit Color TFT screen... it has 128x160 pixels.... which is more than 1.3" oleds... but I wonder what a desktop would look like on those... https://www.adafruit.com/product/358 I think your main issue is that you want to show a standard desktop computer interface....

How are they connected to each other? Or do you mean you are trying to have them communicate with each other with connections wired as in the diagram in your post, and not from one to another device directly? Are the onboard resistors activated? Which one is master and which slave?

tpylkko

A 1.3 inch oled display will not have enough resolution (and probably is monochromatic) to make running a desktop on it sensible in any kind of way like you can on a TFT or do you mean to run a serial console?

or use DLNA, which is "MiniDLNA is server software with the aim of being fully compliant with DLNA/UPnP clients. The MiniDNLA daemon serves media files (music, pictures, and video) to clients on a network. Example clients include applications such as totem and xbmc, and devices such as portable medi...

But it probably will not be consuming the absolute theoretical max at all times (because presumably you are playing music or sounds which are intermittently moving the speaker). Also you can do a lot lower the power consumption of the pi depending on what you need. For example you can turn off the h...

Right, ok.

Are you sure? Where exactly has it not been recommended? I have always upgraded from one release to the next That said, I recall that there was enough patches on to the base Debian from RPF in Rasbian that going from strtetch to buster was not just a matter of apt full-upgrade, there were instructio...

You need to look at some of the benchmarks that other people have already done and posted numerous times. As far as I recall, Samsung and Sandisk cards have mostly take then top spot. Also there are many posts in the forum about A2 and all that. I think a general rule of thumb is that the markings o...

the pimoroni speaker pHAT is almost the same price as that speaker, and it has a DAC,, an amplifier and a 2W speaker in RPi zero form factor. however, I am not sure about the power consumption of it (for batteries)

tpylkko

google also has a zoom clone called "meets". so it has a client (and probably a chromium addon) and a webpage for conferencing. I wonder if it would run any better than Duo?

tpylkko

zoom also has a chromium plugin, that has been used on rpi, see:

Zoom has a linux client. But I have no idea if there is a ARM version

EDIT: quick glance appears to only 32-bit and 64-bit x86

I believe that there are software out there that does something almost like this already. For example, GNOME software has software classified on use basis and ratings by users, I believe Ubuntu has something similar. I realize that these don't include rpi specific software, but I am not mentioning t...

This document is a bit old but it tries to list and discuss some of the viruses that have been discovered targeting linux systems: https://help.ubuntu.com/community/Linuxvirus If you browse that stats on pages like https://statistics.securelist.com/en/on-access-scan/day you will notice that most mal...

I don't know what Filestream is or what it does, but when I access google drive through nautilus (the file manager) it works as described in this page:

https://support.google.com/a/answer/7491144?hl=en

So how is it different? What am I missing?

tpylkko

then there is also the pinebook (there is also a tablet and a phone there if you look). In their promotional paragraph in this page, they claim it is like "chromebooks people convert to linux but better".

doesn't raspbian/rpi have the magic sysrq? I have never tried, but this is what corresponds to "alt+ctrl+del" to reboot in case of a lock down on linux computers. Never tried it on rpi...

edit: in case some one does not know what this is about:

it might be expecting another version of the pandas library

This does not answer your question directly, but I wonder if you are aware that you don't need to write a service to monitor the button and issue a shutdown command, because you can do this just by changing the config files for the kernel? You can eve use the same button to wake up the pi (not sure ...

If my memory serves me, ABS allows for many more ways to polish the surface after the print, however. But PLA is more environment friendly. It is true that when you take the part of the printer, it often looks rough, but it is possible to use many post-processing methods with solvents, sanding, heat...
