Linux Foundation Certified System Admin (LFCS) course overview and test recommendations
This post is for anyone pursuing your LFCS certification and my experiences having done the online-course and taken my first pass at the test. I'm not looking for any flame wars about the pros or cons of this course vs that course or this cert vs that cert. This just to pass on my experience for anyone else in the same boat in the future.
​
**My Thoughts on + Experience with the "Course"**
* tl;dr: Don't expect to take the course and be prepared for the test.
* I purchased the online-course + test (+retake if necessary) when it was on sale in December
* The course is a glorified pdf with occasional chapter introductions by an instructor.
* You're typically introduced to an idea or set of tools and might get 1 to 3 examples. At the end of the chapter, you're typically given 1 to 5 labs which consist of a couple tasks to do with some of the stuff you learned about. Not very thorough, but the labs were where I felt like I learned the most.
* The tests are usually 1-10 multiple choice questions per chapter that only tell you if you're right or wrong and don't elaborate on why the correct answer was correct.
* There is a forum for questions, and they're well monitored, but typically the answer you're given is to try on a different distro. And don't get me wrong, they were very polite and seem like helpful people.
* The Linux Foundation folks are also strangely hostile at the thought that they should be teaching to what's on the test and that this course should prepare you for the test, despite being bundled with the test.
* If you're strapped for cash, you might get more bang for your buck out of a book on Linux, than the course. That said, the course isn't super expensive, and I certainly didn't feel like I came out of it knowing less than when I started or anything.
* [I found a link online to a practice test](https://training.linuxfoundation.org/wp-content/uploads/2019/04/LFCS-Practice-Questions-v1.0.pdf) the Linux Foundation put out that for some reason wasn't included with my course (or it was and I missed it somehow) that I probably got more use out of than anything else offered by them.
​
**Tips for the test** (The following is in the order I think of them, not necessarily by importance):
1. Know "find" inside and out. Know how to do it with rights, how to do it with dates, how to use the -exec command. If I had known this tool better, I'd have cruised through probably half the test much more quickly.
2. Ensure you know how to create bash noscripts. Not necessarily super complex ones, none of my questions involved using \[ \] or anything.
3. Know "tar" inside and out. These are usually pretty easy questions, but question #X will have 6 sub-parts and can be time consuming if you're looking a lot of stuff up.
4. Brush up on directing STDOUT, STDERR, etc
5. Be real good at creating/editing users/groups
6. Be prepared to use "visudo" and make adjustments to the sudoers file.
7. Be aware how to change your IP, your hostname, your gateway, and ports
8. Don't forget about attributes (lsattr and chattr)
9. You will not be allowed any notes, so don't rely on a cheatsheet or anything, but they do let you use man pages.
​
These are just my thoughts for anyone else who loves Linux, but like me, doesn't have any friends/family who have ever used it to get advice from. Hopefully someone gets some use from this some day.

Does it seem like Linux Desktop Environments have regressed since the mid-2000s?
For those of us who were users back then (or earlier), there was a window compositor known as Compiz. It provided a lot of functionality that's just plain gone in most environments now, even more than a decade later.
Lots of visual effects, such as the more flashy desktop cube, wobbly windows, window opacity, and hundreds of other effects that actually leveraged 3D acceleration hardware instead of letting it languish unused. While most environments have some amount of compositing, it's usually an extremely stripped-down subset of what Compiz could do 10 years ago.
But here's one that vanished which actually increased my productivity moderately: the widget layer. Press a hotkey and a secondary layer superimposes itself over whatever desktop you're in, holding certain pinned widgets (or apps) you want available everywhere, but out of the way until needed. Maybe stash Slack or Discord in there, or some sticky notes. Why not take the idea further and have a different layer per hotkey? While it's possible to do that with desktops, there's a certain benefit to having the additional layer transposed over the current viewport.
Compiz worked perfectly fine for me in an underpowered Samsung NC10 netbook from 2008, and yet there's no equivalent for 2020 hardware. It may be a stretch to say LDEs have outright regressed since 2008, but they've definitely lost something since then, and it's a shame. I think about Compiz fondly every couple years and spend some time looking around at current environments, but always find them missing something (or a lot of somethings).
Unfortunately after Compiz was abandoned, the code wasn't really picked up and integrated into anything else. Canonical adopted it for a while in Unity, but even that's essentially gone now. KDE, Gnome 3, Mate, Cinnamon, etc., all have a bit of visual flair here and there, including Expose-style scaling or desktop views, but it's all very... sanitized. Few options or configuration, and a very "Windows 10" or OSX feel.
Perhaps that's how we know Linux has finally "matured" and that "this year is finally the year of the Linux Desktop". I could be wrong though; let me know if I am. I want to be wrong, actually.

Ive just spent 18 months running Linux on a daily-driver laptop using two USB sticks. These are my observations.
I inherited a relatively high end 15" laptop years ago, and when I swapped out a hard disk I tore the small zif-like socked from the mainboard the hdd attaches to. Its not really practical to repair, so I needed to find an alternative. I thought about a USB install, bur for various reasons not practical to do this with windows 10.
I read about MX linux which is based on Antix and has some development around USB sticks installs so I took the plunge on a USB 3.1 sandisk ultra fit. I chose this because it has a very low side profile - and unlikely to get knocked/ damage usb port when in daily use. The laptop pre-dates 3.1 so the slot was 3.0. Therefore running at 3.0 speeds.
The only other USB based OS experiences I had were unraid and openelec. Both were positive, but they are tiny os's and run pretty much in RAM, so not taxing at all to storage medium. Full-blown desktop os doing grown up computing a different scenario. I really had no idea how that would play out.
The initial install went pretty much as expected. I set up the software I needed and tweaked the OS /desktop to my preferences. After a bit of use (couple days) I was noticing fairly regular micro-pauses while working. Not a deal breaker, but not optimal either.
I figured this was due to disk access load so opted to split /home off onto a second drive. I purchased another 3.1 sandisk and did this, which solved the issue. Subsequently the experience was smooth and responsive.
Use of the machine is mainly document editing, some graphic design, a bit of video editing, lots of internet surfing, some vm stuff.
At the outset I imaged the OS usb, expecting to have to replace it every few months and wanting a quick deployment method.
I carry around a spare in my laptop bag just in case.
In 18 months of near daily use I have swapped out the usb due to failure once. This surprised me TBQH. I did not expect it to be reliable.
Observations:
Speed feels to me faster than a 5400rpm hdd. Seems quicker and more responsive, but have not run any objective measures. It feels like an SSD to use.
OS USB is 32gb and that is - as it turns out - ample room for the os (about 6 months ago I swapped to Ubuntu Server with XFCE as the desktop) - I love this about it. The USB stick was $11AUD.
Reliability has been excellent. Its been reliable, which was NOT what I expected.
\-
Mainly posting this as i have not seen a lot of this sort of thing posted and thought others might be interested to hear how it went. I doubt many people would want to run out and try it, but I hope its interesting for anyone curious.
Linux is an amazing OS to be so versatile. Its allowed me to keep this l aptop going where otherwise I would have been up for either a costly mainboard or machine replacement. I feel really fortunate to have this option and so pleased with the experience.

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!

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.

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?
