journald eats up disk space, limit journald max disk space use

Journald take Gigs of disk space, which is not really needed by desktop users. This is especially the case with Fedora.

#Journald huge space usage fix
sudo journalctl --vacuum-size=100M
sudo journalctl --vacuum-time=10d

sudo sed 's/#SystemMaxUse=/SystemMaxUse=100M/g' -i /etc/systemd/journald.conf

Window manager recommendation?

Hi everyone, so I'm planning on installing endeavour os on my laptop later today and I've seen that the trend these days seem to be window managers instead of DEs, at least based on what I keep seeing on r/unixporn. I was wondering what window manager is recommended for someone who has never used one before, in terms of setup and configuration and just overall ease of use. Also, do window managers support floating windows instead of the regular tiling behaviour? Just wondering since my old laptop has a small screen.

Edit: I plan on installing xfce as well alongside the window manager just because someone else might need to use this laptop

Linux May Have Saved My Life

Very simple: LINUX SAVED MY LIFE

I fell in love with technology a long time ago.

Somehow, I let my dad talk me out of it during high school...

But the interest never fully subsided. In fact, over time I found technology intertwining with my various interests, hobbies, and passions...

Adulthood slowly crept in, and along with it came responsibilities. It wasn't long before I felt like it was too late for me to get more hands-on with tech.

In 2018 I contemplated joining a coding Bootcamp, but the all-day intensive schedule didn't mix well with my work schedule and home life (married with 1 kid).

ENTER LINUX: in May of 2019, a friend/colleague of mine introduced me to a Linux class. I signed up and began class in August of 2019. Prior to this, I dabbled a bit in Ubuntu and Kali Linux, but not properly. This time I was able to learn how to use the command line with CentOS/RHEL.

I took my windows hard drive out of my Lenovo T450, put a new one in, upgraded the ram to 16GB, and switched to CentOS. The year is now 2021 and not only am I fluent in Linux, but I've also completed an AWS Solutions Architect Associate training, and I'm preparing to take exams for several certs. By the end of 2021, my goal is to accept my first tech/IT job and go from there.

Seriously, Linux changed my life, and it helped me truly understand the structure of computers and the key concepts behind information and tech. I am now convinced that kids should be taught the basics of the command line and Linux. ALL KIDS EVERYWHERE... and adults too.

It shouldn't be just for nerds and tech wonks. It should be for everyone.

P.S. Thank you for reading. I haven't shared my thoughts online in quite some years and I had to get past my usual overthinking to come here and just post. I'll be back soon to share other thoughts I have, however incomplete those thoughts may be.

Long Live Linux, in all flavors!

Beginner to Linux

Hello,

I am getting more into coding, and I have started to realize that most things are done on Linux, so, I wanted to buy a Rasberry Pi, now, money is a bit on the weak side right now and so I wanted to get the Rasberry Pi 3, will I need any additional things like an SD card, and also what are the disadvantages of getting a Rasberry Pi 3 rather than a Rasberry Pi 4?

Hooked after a series of book/CD combos circa 1998 exposed teen me to *nix (RH/Mandrake/SuSE) over 22 years ago, I, obligatory "Arch BTW", just learned `cal` outputs a well-formatted calendar. So, r/linux what's your humbling "huh." moment?

Would i have used it had i known about it before now... who's to say! Anyone remember those Linux Book / CD combos? Walnut Hill ring a bell? I loved going to Hasting's and seeing what new book and CD-ROM was waiting there on the single shelf for ~~nerds.~~ PC advocates. :)

Is there any way to do gifs of one line of my nvim?

Hi! I am making my vim cheat sheet and I thought it will be nice to put next to command/key gif which will show that key in action. I don't want to make gif of full size of my window. Many command has effect on small area of text. I want to record as small area of text as needed.

Maybe even a way to write every "state" of gif manually. E.g. showing D key in action:

{1 frame, 100ms} ` I am making my vim {cursor is here}cheat sheet`;

{2 frame, 100ms} `I am making my vim `;

Thanks for any tips.

Is ClamAV Good and Does it Really Track/Collect Data?

I stumbled across ClamAV, which seems like an okay Antivirus for Linux.

It adds a small bit of extra security, especially for emails so it's better than nothing right?

Well, I can't find much info or personal reviews about it on the internet.
And their privacy policy redirects to Ciscos policy, which states that they do collect data etc.

Seems very bad of a Linux AV to collect user data...
But does it really do that and can I turn it off somehow?

I'm kind of a Linux noob...

Thanks for reading!

Anyone still using LXDE in 2021?

As the noscript says basically. I like the idea of a simple, very lightweight DE but development stopped a long time ago now. I know LXQt is supposed to be the successor but it seems to be pretty buggy from what I have read.

Are folk still actually using LXDE and if so, what problems do you have/sacrifice s you have to make?

Linux on ARM future

I'm just curious how serious are popular distros about it.

Knowing that Apple have potential to bend the market to their will in my opinion this can be a great opportunity for Linux to profit from this movement. Please correct me if I'm wrong, but Android is built on Linux, meaning that technically with little twinking android apps can run natively on Linux ARM device. Repercussions of this could be huge, potentially cutting off guard big players like Microsoft once again.

May the history can repeat.
