Just released a new version of the disk usage visualization terminal tool - VIZEX

So finally got some time during the winter break and release a new version of the terminal disk usage visualization tool called [vizex](https://github.com/bexxmodd/vizex), where you can graphically display each disk usage/availability in the terminal and modify colors and graph types.

In version 1.5.1:

* Added option to display battery information if you are on your laptop
* You can save the output as a JSON or CSV
* Corrected bugs and refactored for better readability

Please, try it out! Any feedback is much appreciated!

rclone vs onedrive client

I'm looking to live continuous sync onedrive to my desktop. Which one is better rclone or the dedicated onedrive client maintained here github.com/abraunegg/onedrive? Both look good.

Energy efficiency with Linux

Hi everyone,

​

I've been using Linux non-continuously for the past 6 years on laptops and tryied some distros (Ubuntu, Xubuntu, Mint, Open SuSE). For me, the best pros of Linux over Windows/MacOS is the highly consistent UI (Windows looks like a time machine with interfaces from XP to 10), privacy and support for programming. Now I have been using Ubuntu continuously for the past 5 months on a master degree program. Ubuntu 20.04 is the first LTS that I really enjoy!

​

But one thing stills sucks on Linux: energy efficiency. In my laptop (Asus VivoBook) I have some 2-4 hours of usage away from the charger with Windows 10 and it's almost impossible see the computer with his vents on max or any heat. On Linux, otherwise, the machine use to make some heat on the keyboard and the battery almost never passes 1.5 hours away from the charger. I'm using CPU Power Manager to limit the frequency of the processor and save some energy, but it's not resolving.

​

The question is: what are the main differences between Windows and Linux in this area? Are there any attention of the developers to this area? I really want to know why Windows even with a lot of background process, high usage and inferior performance achieving better results in the energy efficiency.

eBPF runq latency metric value

I have been looking at the eBPF `runq latency` metric and was wondering for a given application (e.g. containerized microservices) what should be an acceptable range for this metric?

My line of thinking was that because this is essentially a scheduler metric, and the CFS scheduler usually lets the thread run for a few milliseconds time quantum, then an acceptable range would be up to a few orders of magnitude (say 5x). Any thoughts?

Installing Zoom via Wine

Hi
These days, I'm using Zoom every day, but it sucks that the native Linux edition is so much inferior to the Windows one. (It doesn't have push to talk and reactions, for example)

I was thinking: will Windows edition Zoom work well on Wine?

Is there a way to install Zoom via Wine or an other way to get the missing features from Windows on Linux?

I tried the flatpak version too but it's identical to the one found in the repos, and their site.

Also, I tried using installing via Wine but it doesn't recognize my laptop's camera, and meeting links didn't work either.
Have someone succeeded to install Zoom via Wine properly?

i came across what people call the ethical source movement (i dont believe that software licenses will solve the worlds problems)

https://ethicalsource.dev/

while its great that they support human rights i fail to see how this fails to stop human rights violations as its not like countries that violate human rights will all the sudden respect a software license

another issue is that you are expecting that same government that violates people rights to all the sudden enforce your software license and not use your software

Noob question about chown

Sorry about asking this but I'm not sure how to ask such a specific question anywhere else.

​

I used the following to gain read/write permissions on an encrypted thumb drive:

user@user-MacBookAir:/media/truecrypt1$ chown -R $USER .

​

Later, I read that chown -R $USER \~ would revert things. So i used it, then formatted the thumb drive since I was done with it. Now I'm looking and realizing that /media/truecrypt1 wasn't on the thumb drive, but in my file system. Can the commands I used have messed anything up? Can anything have been left compromised?

Implementing something like latte-dock in GTK.

Hello!

I've embarked on a rather stupid journey to program everything in my DE in Rust by myself (display manager, window manager, all apps, etc...). I've gotten pretty far, but I'm stuck on how I might implement something like latte-dock in GTK.

I assume I just pick a different top level, but I have no idea which one to choose, or how to write code for it. I'm obviously not looking for code, just for someone to point me in the right direction.

Hardware Acceleration is working on Google Chrome!

I know Google Chrome isn't popular in Linux masses. But hey it works. I am on Manjaro. Downloaded Google Chrome using aur. Turned on this flags in chrome://flags

ignore-gpu-blocklist
enable-gpu-rasterization
enable-accelerated-video-decode

Installed enhanced-264ify extension. https://chrome.google.com/webstore/detail/enhanced-h264ify/omkfmpieigblcllmkgbflkikinpkodlk

I can see "MojoVideoDecoder" on chrome://media-internals

00:00:09.406 kVideoDecoderName" MojoVideoDecoder"

Also, I installed intel-gpu-tools
sudo pacman -S intel-gpu-tools


and running sudo intel_gpu_top
I can see the Video/0 moving.

So, Google team just enabled Hardware Acceleration without much news?

Why do you have to use Sudo commands to install programs instead of double clicking?

I'm a person who has uses Ubuntu just to watch a movie and that's about it. So my knowledge isn't that great on linux.

I like Ubuntu but I wonder why you have to use Sudo commands to install programs. On Mac and Windows you can just download a file, double click it and there it goes. Why not on Linux?

I have asked this question a couple of times to Linux users but I always get an answer that it is safer. The other answer is that you don't need to install software because (at least on Ubuntu) it is in the software centre. I doubt that both of these answers are correct. A double click can trigger a sudo command or trigger asking for a password . That would be just as safe in my opinion. And not all software is in the Software centre.

I'm not asking this out of complaint but out of curiosity why this way of installing is needed.

What do you guys think about Flutter for development of Linux apps

I'm a flutter developer and a Linux enthusiast so it excites me. I want to know what you guys think about it and why.
For a long time I've wanted to get started with development of applications on Linux and Qt or gtk looks quite intimidating. Having Flutter create Native app for linux would be a game changer

Thoughts on Feren?

I just tried Feren OS out and I've got to say, it's the most aesthetically pleasing distro I've used. Beats elementary by a mile to me on appearance. I'm not a huge fan of Vivaldi being the out-of-box browser, but the whole OS works just as solid as any other Ubuntu-based distro I've used. I'm wondering if anyone else here has tried it, and what your thoughts are? Thinking of switching from Linux Mint.

What are everyones thoughts on Fedora Silverblue?

Found out about fedora silverblue a few weeks ago and I think its probably the most exciting shake up to the linux desktop space there is.

They have an explanation on what silveblue is here but the tldr is they turn the OS in to an immutable image which gets mounted as read only and any user programs and user data are separate from the OS.

The advantages:

Almost impossible to break your OS
Updates become very safe since they do not need to account for your own modifications or migrate previous data, its just a case of swapping the old OS image for the new one
Updates can be easily reverted

Downsides:

Package manager removed since it can no longer insert files in to OS dirs like /bin

Silverblue offers a few alternative workflows for package management.

One being a tool called rpm-ostree which creates an additional layer over the OS image which contains your package. You must reboot to apply the layer though.

The main suggested workflow for applications is now flatpak. Probably controversial but there are some neat advantages to this method

The third being a tool called toolbox which can create and enter podman images which contain a more standard fedora install including dnf which has access to your home directory. Best method for setting up a development env and also has the advantage of allowing multiple separate environments.

What does the community here think? Will some variant of this idea become the default in linux distros?

hey everyone

metasploit isnt working after i did apt-get update/upgrade.

\> Executing “sudo msfdb init && msfconsole”

[sudo\] password for kali1:

[+\] Starting database

[i\] The database appears to be already configured, skipping initialization

Unable to find a spec satisfying metasploit-framework (>= 0) in the set. Perhaps the lockfile is corrupted?

Run `bundle install` to install missing gems.

i ran bundle install and the output was: could not locate gemfile..

if anyone knows whats going on here please let me know
