Linux is environmentally friendly

Sun, 2017-07-23 10:16

Most people I know buy a computer with Windows, use it for a few years, then when it starts to get slow (because... Windows), they throw it away and buy a new one.

I only use my computer for basic things and I know how to install Linux, therefore I don't need to buy computers. I just take the "old" ones my friends and family are throwing away, install a lightweight distro and... that's it!

Of course I am not the only one. I know some universities do this to provide free computers to their employees. Some associations do this to give computers to inhabitants of poor neighborhoods, along with a basic teaching of the OS. But I think there are still too few of these examples, and more importantly, more people should be aware of this and use linux for this reason!

Maybe I am wrong, but I don't think people presenting Linux and its advantages talk enough about its potential for reusing old hardware. Most often they need to convince non-technical people: this is clearly something non-technical people can relate to:

  • It is less harm made to the environment
  • It is less harm made to one's budget

What functionalities does systemd have that so many things depend on it, and what are the benefits of alternative inits?

Sun, 2017-07-23 09:50

I'm not interested in knowing why systemd supposedly sucks, I'm not savvy enough to get the technical arguments levied against it or for it and I've seen lots of them already in this subreddit.

So supposedly lots of software depends on systemd now. What parts of systemd are they actually using and for what? What did they use before systemd? What benefits/features did systemd bring to the table?

And for those of you who don't use systemd or advocate for other init systems: What alternative inits are there and what are their advantages (and possibly shortcomings)? Basically, tell me about the init system you like, not the one you oppose/dislike.

"Little Backup Box" Help Needed (Photography SD Card Backup Tool)

Sun, 2017-07-23 06:01

I am trying to run Little Backup Box on my Raspberry Pi 3B and have not been able to successfully run it. I believe I have installed it correctly as I have followed the directions to the dot and I see the process in crontab. When I put in any USB device first (I tried multiple USB drives, even with a powered USB hub). Once I plug in my SD card via an adapter, it starts to copy the files to the /media/storage/"card ID that it defined" and does not copy to the USB drive. It then seems like it fills up my OS drive and once that gets full, it powers down. I am running the latest Rasbian Jessie software and have it on an 8gb card.

Does anyone have any experience with this program or with anything in the shell script that could fix this problem?

Thanks for any help/advice!

Raspberry Pi and Samba

Sun, 2017-07-23 05:06

If I wanted to use a raspberry pi with samba for a home file server will I run the risk of SambaCry infecting the server or am I relatively safe?

Is it possible to hook into/observe the Linux filesystem

Sun, 2017-07-23 00:22

Is it possible to get notified of any file system activity and record the details - what I want to do is build a catalog program that stays update dynamically.

So e.g. whenever a file gets created/deleted/moved the code gets notified and updates its catalog index. This would then allow instant lookups among other features.

Programs like iotop, lsof do some things like this so there must be some mechanism for this.

Richard Stallman Linux proportion in GNU/Linux

GNU/Linux proportion

I have been seeing the above image used on slides by RMS in many of his presentations. However, the proportion that he gives to the Linux kernel with respect to the GNU tools is what bothers me.

He seems to always try to give a minor importance to the kernel piece (the part that they failed to develop. GNU Hurd, what a joke...). He even calls the set of GNU tools an operating system! That was missing a small piece of software, which is the kernel.

Is that I'm seeing that aspect in his talks since I'm kind of biased, or it is really the way I'm seeing it.

Why all package managers download all packages first and then install the updates?

Sat, 2017-07-22 11:12

While I was updating my system, I realised that while updating, all the package managers that I used (pacman, apt/apt-get, yum) download all the packages first and then starts installing the updates. It might sound obvious at the first hearing ("of course it needs to download first to be able to install"), but they can also start installing packages as they finish downloading dependencies. It would surely be faster.

Does anyone have an idea why it's not the case, and who would be interested in a proof-of-concept prototype that achieves this panellisation? Thanks!

In terms of Free Software movement, can we describe current world as TiVoized?

Sat, 2017-07-22 11:00
  • AMD and Intel have proprietary firmware in their CPUs that has full access to your RAM and network even when your PC is offline
  • Most modern routers have closed-source components in their firmware (companies use FCC certification as an excuse)
  • GSM modules in smartphones are all closed-source and, in fact, are second operating system working independently and handling your cell data and network
  • both AMD and NVIDIA have closed-source firmware for their GPUs (AMD is better nevertheless for having FLOSS driver and providing recent versions)
  • Most motherboards have proprietary UEFI that also has full access to your hardware
  • For majority of devices in IoT you don't even know what's in there and what it does
  • Android ecosystem is becoming more and more closed with Google mandating no-root with their apps, SafetyNet and depending on proprietary Google Play Services

We have some options here and there, reverse-engineering efforts like Freedreno, Etnaviv or new developments like RISC-V, but everything of that is not yet consumer-ready. So just to make things clear between us, can we assume current hardware world as TiVoized?
