Enjoying the free edX course on Unix Tools (as a mid level engineer)

Course Link: [https://www.edx.org/course/unix-tools-data-software-and-production-engineering](https://www.edx.org/course/unix-tools-data-software-and-production-engineering)

I just finished the first week of this course and I quite enjoyed it! The best part so far was definitely section 1.5. It says it’s about command line arguments but I just learned so much from that one short video.

* unix wildcards are expanded by the shell so all programs get them equally
* What is the difference between $ and ${} ?
* When to use '' vs "" for noscripts?
* Using the output of a command: $(date) vs \`date\`
* What is a [here document](https://en.wikipedia.org/wiki/Here_document)?

Most of the stuff I’m familiar with but the videos are so concise and well done I don’t even mind watching them. Also just wanted to say that while I do have a few years experience as a software engineer I still find the course to be quite useful. Videos are so short there's not much to lose if you already know it.

Hope someone finds use from this :)

"thanOS"

Surely I'm not the the first one to think about this(or am I?), but is there a linux OS that has Thanos characteristics? Like one click complete data wipe, one click sudo or whatever the genius r/linuxmasterrace can think of to make it more "thanOS". Please make one!

Looking for an open source, multi-platform app that will allow me to remotely teach non-techies SQL (me: Linux, them: Windows 10)

I'd like to teach two, non-techie ladies some basic SQL/DB stuff. We had planned to do this face-to-face but with coronovirus, we now have to do it remotely.

I'm looking for an an open source, multi-platform app to help us with this. I have seen some web-based stuff but to be of any use we would have to pay and as this is all for a charity, their funds won't stretch that far. Any help greatly appreciated.

what are the risk associated with sharing project ideas in regards to patent trolling?

This is something I've been curious about but don't have enough contextual knowledge to figure out how to effectively get an answer. I'm finishing up college (hopefully) in the fall, and while I know the basics of open source patents, and software law, I don't know much about IP laws around abstract ideas for software, other than they exists.

I have a lot of project ideas, and granted some of them might be dunces, but as far as I'm aware a few of those ideas don't have an equivalent implementation in either proprietary or open source software(though some of them do, just not in linux or the open source community), and would fill a niche for users. I want to actually discuss these ideas with other developers, both for the purpose of collaboration and to flesh out the details of implementation.


My concern isn't that other developers are going to take some of these ideas and run with them, I would prefer they did (it means worst case scenario the idea doesn't end with me or my time constraints). Nor am I concerned that someone might implement the idea in proprietary software and make money off of it while contributing nothing to the development of an open source alternative(or that I won't be able to make money off it because of that).

My main concern is in the process of sharing the ideas and discussing them with other developers, I might wind up limiting my ability to work on it in the future, either because another developer creates a proprietary implementation and patents the particular method I was discussing on an open forum, or a NPE will patent the concept premptively as a way of potentially making money if I or any other programmer develops/publishes it. I mainly want to make sure I'm still free to pursue development at my leisure.

for example, as far as I'm aware, the idea of 3d printing isn't patentable, but particular techniques for plastic printing are(even if those techniques have yet to ever be implemented), but I'm unsure how specific the constraints of patenting a technique are.

How much of a risk is this in practice?

What is and isn't patentable when it comes to ideas?

if you are a more seasoned open source programmer, what would you recommend that I freely discuss, and what would you recommend that I avoid disclosing prior to implementation?

Note: Sorry if the noscript is ambigous, I couldn't figure out how to properly word it.

LPT (Linux Pro Tip): Keep your home folder "clean"...

I wonder how many r/linux subscribers did a double take because they're also r/lifeprotips subscribers.

Anyway, I was just listening to a podcast where the hosts went on and on about how to keep your home folder clean. One of the hosts said that they actually reinstall their OS from time to time for this purpose...wait, what? Why?

My solution has always been pretty simple for this: just make a new user. New user = new home folder. Move big files that you know you want to keep so it doesn't take up a bunch of disk space. Dot files are easy enough to move from one user to another. Take your time picking and choosing which files you want to keep. Personally, after I haven't touched my "old" user after a couple months or so, I just save the old user's home folder to my NAS (just in case) and then 'userdel -r olduser'.

Voilà, just like new...because it is new. I've also found it interesting to diff between my new and old users' home folders from time to time to see how my dot files have changed.

Hopefully this keeps some of you from feeling like you need to wipe out your entire hard drive just to clean up your home folder.

Reverse SSH Tunneling, how to access application/services on the raspberry pi?



Hi, so I'm quite new to ssh tunneling, I needed some way to access my raspberry that's connected to 4g network that can't be port-forwarded.

&#x200B;

https://preview.redd.it/rz0gtoouuxn41.jpg?width=1152&format=pjpg&auto=webp&s=d4a5a565a7c876561f0b42db975903d392f94c4d

I've managed to configure autossh on m pi4 to google cloud, and I'm able to ssh into the pi from google cloud.

Only thing I'm not quite sure is how exactly do I access services running on the pi with gui? Like nzbget running on port 3456 or other services running on different ports.

And is it even possible to access other devices (cctv for example) connected to the same router as my pi?

I added the autossh noscript to systemd,

`[Unit]`

`Denoscription=Phone Home Reverse SSH Service`

`ConditionPathExists=|/usr/bin`

[`After=network.target`](https://After=network.target)

&#x200B;

`[Service]`

`User=pi`

`ExecStart=/usr/bin/ssh -NTC -o ServerAliveInterval=60 -o ExitOnForwardFailure=yes -o StrictHostKeyChecking=no -i /home/pi/.ssh/id_rsa -R 6667:localhost:22 pi@googlecloud_ipaddress`

&#x200B;

`# Restart every >2 seconds to avoid StartLimitInterval failure`

`RestartSec=3`

`Restart=always`

&#x200B;

`[Install]`

[`WantedBy=multi-user.target`](https://WantedBy=multi-user.target)

I also found another autossh noscript from raspberrypi forum but I couldn't get it to work which I couldn't post here since external link is not allowed

Idea for a low-cost, low-power, 3d-printed raspberry pi-based backup

My problem is that it's tough to get good backups in remote locations.


So, I'm looking at making a low-power, low-cost backup machine (using ZFS, but you could use it with any others). It seems like the pieces are coming together, and I want to gather some thoughts before I dive in. Let me know how I can improve the design - or if you think there might be others interested.


Spoiler: I'm thinking of using a 3d-printed case.

Installing Linux on an M.2 SSD - a few questions regarding duel booting on my PC, grub bootloader, etc.

I just learned that my [motherboard](https://www.newegg.com/asrock-b450m-pro4/p/N82E16813157843?Item=N82E16813157843) has an M.2 slot to install an M.2 SSD, which I plan to install Linux on

I go back to school this April to pursue a degree and career in Enterprise Networking/IT - not sure specifically which direction I want to go, but as I begin to learn I know I'll notice areas I like more than others.

Anyway - I'd like to start learning Linux to give me a head start. This quarter I am taking a class called Ethical Hacking which uses Kali Linux. I am reading that this is the best way to learn and get comfortable with Linux is to just use it for my daily computing tasks. I know it's pretty easy to install Linux on an a SSD for that matter but that's pretty much it

I keep reading about the "grub bootloader" which I am kind of confused about, so I was hoping I could get some more info regarding it, how to install Linux with it and easily which between each OS. Does the grub bootloader make it so I don't have to jump into the BIOS every time and pick which drive I want to boot from? Does it make that process smoother? Is the grub bootloader automatically installed with any distribution of Linux I choose? Or it something I have to manually install myself once I install the OS? Any other info regarding it is appreciated.
