Weird problem with rc.local on Raspbian 7

If I edit something like rc.local, change passwd, or similar, the change will not persist after a reboot. Everything reverts to the previous version.

Any ideas? Maybe it has entered some kind of mode mapping the live operating system folders like /etc/ to RAM or something. The command df shows correct mount points, so I'm unsure what is causing this.

Of developers and snaps: theming

First of all a disclaimer. Please don't turn this post into a "SnAp SuCkS, uSe ApPiMaGe oR fLaTpAk". I believe that different app formats can coexist and as of now they each have their strengths and weaknesses. What I'd like to concentrate on here is the theming of snap applications.

The question is, why do snap applications behave inconsistently in regards to theming? Let's consider to somewhat big programs, GIMP and Firefox. Gimp respects the system theme (those that are supported, I've tested with yaru, adwaita and the elementary theme) while firefox (ubuntu 19.10) doesn't. Why do they behave differently? Well the answer is simple: the gimp snap is connected to gtk-common-themes whereas firefox (and the majority of snap apps) isn't.

So developers, please connect your snap applications to the [gtk-common-themes](https://forum.snapcraft.io/t/how-to-use-the-system-gtk-theme-via-the-gtk-common-themes-snap/6235) package. Your apps will look a lot more consistent with the rest of the desktop and this will lead to a more pleasant user experience.

Canonical should push BTRFS instead ZFS out-the-linux-tree ?

Why Canonical no help to push and improve BTRFS ?

Why go to ZFS that is out of the Linux tree?

Killing the elephant in the room - the userspace low memory handler ability to gracefully handle low memory pressure

In the summer, there was a thread about the inability of the kernel to gracefully handle low memory: [https://www.reddit.com/r/linux/comments/cmg48b/lets\_talk\_about\_the\_elephant\_in\_the\_room\_the/](https://www.reddit.com/r/linux/comments/cmg48b/lets_talk_about_the_elephant_in_the_room_the/)

Beginner linux projects

Hi all

Looking for some advice on levelling up my linux skills. I'm currently working in a level 1 support role in a mainly linux environment. I do basic troubleshooting and have automated a fair amount of manual tasks in the past. I'm not a whiz kid at noscripting by any means but I would like to improve my skills to the point where I'd like one day down the line to become a linux system administrator.

I have a raspberry pi at home and I'm wondering is there any projects you guys could suggest that would help me towards this goal in the real world. Thanks a lot in advance.

Coming back to Linux...partly.

My home IT estate is Windows Server/7/8.1/10 and some Mac stuff, mainly because those products are how I make my living. I toyed with Ubuntu between 8 and 11 - a decade ago - but it was a bit awkward and I was out of my comfort zone back then. We just didn't get on.

Last night, my sofa laptop (a cheap-ass old Windows Dell Latitude) threw its toys out of its pram, so I had to put in a new hard drive. And I thought, "Heh. Why don't we go for Linux on it?" I went for 18.04.3 LTS.

I'm *impressed*. The setup was clean, configuration/personalisation is easy, the experience is seamless and it runs like a buttered otter. It's still possible to get it all wrong - I trashed my original install trying to install Wine - but it really feels production-ready now for someone like me who is IT-competent but not necessarily knowledgeable about Unix things.

Top Games on Linux

Hi guys,

Im new to Linux, what are the top games I can play?

lsof output looks crazy to me

$ lsof | grep -v PID | awk '{print $2}' | sort | uniq | wc -l

294

$ lsof | wc -l

110829

$ echo "scale=3; 110829 / 294" | bc

376.969

Now I just have a little old laptop. It is already a little surprising that there are 294 processes, but how is it that the average number of files open per process is almost 400???

Recover SD card that does not list with lsblk

Trying to recover a microSD card from my gopro, hoping there are some powerful FOSS tools to help me out!

`lsblk` brings up nothing (as in, only displays the other *known* drives)

`dmesg | grep usb` also only mentions USB drivers

`dmesg | grep sd` only mentions SSD and other known stuff

Both my laptops (HP Stream and Macbook Air - both booted to Arch Linux) behave the same way, so I don't think its the card reader.

All the recovery tools (photorec/testdisk) want a `/dev/sdX` as input, so they don't seem much help. Note: `dmesg` tells me that `sdc` is the Macbook's cardreader.

Funny thing is, when I use a card reader and plug it into my android phone, I get a message to format the card. GoPro (Hero 7) does a similar thing - comes up and says only way to fix is to format which wipes all the data.

So... *some* devices seem to at least recognize the device, which gives me hope.

What should I try from here?
