Does Linux have any applications where you can run Windows 10 in virtual mode?

I might be running into some issues with tax sofware not supporting Windows 7 in the coming years. My older Windows 7 system isn't robust enough to run Windows 10 efficiently or effectively.

I was thinking if I can run Windows 10 in a virtual environment within Linux where installation of the virtual box would be virtually effortless?

Laptop usage tracking software

Hi linux users,

I recently thought that it would be great to start tracking how long I'm using my laptop. To be more mindfull how much time I spent at front of my computer so I created small soft that is tracking it.

[https://github.com/Migacz85/track-laptop-usage](https://github.com/Migacz85/track-laptop-usage)

I also implemented in this distro more handy way to suspend computer, - for example checking if the user is sitting at front of the computer before doing it.

If you are using arch/manajro It would be great to get some feedback with installation or general working of the noscript issues.

If somebody is on different distro than arch/manajro, and is willing to install this noscript - I would appreciate an simplified installation noscript :)

Why does Nvidia hate Linux so much?

It just never changes. Nvidia has always hated GNU/Linux for some reason. Never really understood why?

Gaming on Linux

Hello all!

I have been wanting to make the switch over to Linux full time. I have a Nvidia 1080ti and Ryzen 7 3700x. I mainly just play games, I play WoW, COD, and Minecraft. I will also play some AAA noscripts. I am wondering what is some practices that others have when switching to Linux and gaming. I would like to rice it out and use a window manager. I have only used Ubuntu server in the past for just operations. I don’t really have a lot of experience with desktop front ends. I love the idea of Arch but just lack some knowledge of it. Anyone have some sweet setups that they would like to discuss??

Windows Subsystem

I am a new user to Linux, my goal is to start using Linux instead of windows for my future usage to the bioinformatics packages on debian, can I switch to linux using the Windows subsystem layer or it's not worth it?

The reason is dual booting is too much resesrching and I am not up for trial and error that may mess up my files as I have already exceeded maximum drive parition slots.

And VMs keep getting stuck at launching 20% which drove me crazy.

Command line - Documentation

Am wondering where I could find some authoritative documentation on what all the various command line arguments/flags etc mean. For example, what the "-i" in "sudo -i" or the "-vvv" in "pulseaudio -vvv" mean.

Borgbackup is amazing.

Hey there,
since many time borgbackup is getting a great place inside many env. Many user replaced their solution with borgbackup and not only on desktop but also on server side. Solution like bacula, bareos are removed due the great simplicity of borg. Other solution like noscripted rsync are always large used by thier creator.

The most important features are deduplication, encryption and compression that don't need a particular effort to be configured and used, simply create the repo and run "borg create" command and it works without configuration..simply amazing. Better, you don't need to open strange services ports you should use only ssh connection.

Many said that its security level is low due the fact that it uses push and not pull method, many criticized the "obscure" file format (this scares me on what to do when the client completely died and how to recover data using the key and the password), other avoid it because prefer that the server pull the data contacting the client and not viceversa, other don't like that the client (if hacked) could remove all backups when only the server should do this (and from my POV it is true. For this there are solution like borg append and ssh command on key to restrict path).

If you don't like how it works by default, like each client push data on a (logically separated) repository, you can use it like a central server (a similar pull method) with a net fs mounted like sshfs, nfs, samba if you like it. You lose some performances but it works.

Currently I'm using noscripted rsync but I'm starting to playing with it.

I don't know what are the next steps speaking of developing features (there is a place where to read what will be implemented in future release?) but it seems promising. I hope that some new features will be: a central server solution (more performant then sshfs), a file catalogue (if not already provided), the ability to see how many different version of a specific file is saved in a temporal arc. What do you like to have as feature in next borg version?

What do you think about it?

You switched from another solution for borg and in what environments? What do you like more on borg and what not?

I'm considering it seriously!

What are the differences between Linux distributions?

I've just started an Ubuntu Linux course, I installed a virtual machine and run it there. While i was
investigating a little more i found tons of Linux distributions and I start wondering about what if I chose the wrong distribution, or if I wanna change from one to other?. Do they have stuff in common?. What are they used for?.

I would really appreciate if someone clear out my doubts! Thanks :)

As a Gentoo user I had to check what gcc flags are in Clear Linux. Here they are:

`CFLAGS="-g -O3 -feliminate-unused-debug-types  -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=32 -Wformat -Wformat-security -m64  -fasynchronous-unwind-tables -Wp,-D_REENTRANT -ftree-loop-distribute-patterns -Wl,-z -Wl,now -Wl,-z -Wl,relro -fno-semantic-interposition -ffat-lto-objects  -fno-trapping-math -Wl,-sort-common -Wl,--enable-new-dtags -mtune=skylake  -Wa,-mbranches-within-32B-boundaries"FFLAGS="-g -O3 -feliminate-unused-debug-types  -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=32 -m64 -fasynchronous-unwind-tables -Wp,-D_REENTRANT -ftree-loop-distribute-patterns -Wl,-z -Wl,now -Wl,-z -Wl,relro -malign-data=abi -fno-semantic-interposition -ftree-vectorize  -ftree-loop-vectorize -Wl,--enable-new-dtags  -Wa,-mbranches-within-32B-boundaries "CFFLAGS="-g -O3 -feliminate-unused-debug-types  -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=32 -m64  -fasynchronous-unwind-tables -Wp,-D_REENTRANT -ftree-loop-distribute-patterns -Wl,-z -Wl,now -Wl,-z -Wl,relro -malign-data=abi -fno-semantic-interposition -ftree-vectorize  -ftree-loop-vectorize  -Wl,-sort-common -Wl,--enable-new-dtags "CXXFLAGS="$CFLAGS -fvisibility-inlines-hidden -Wl,--enable-new-dtags "`

​

\-mtune=skylake fascinates me. Why no other distro uses -mtune?

​

Of course it doesn't mean the whole system is compiled with these flags. It might or not but we can't be sure.

I share this as I know many people wonder what makes Clear Linux so fast and this file may give some ideas or to inspire for discussion.

Snap Apps not opening after running a command

Hello! I am a very new Ubuntu/Linux user! Unfortunately, I was having an issue with discord, attempted to fix it, but ended up just breaking all of my Snap Apps. The command I ran was
sudo chown -R $USER:$USER \~/snap
How would I fix this? Should I just do a fresh install? Thank you!

The future of distributed shell commands.

Greetings, comrades.

I'd like to tap into the huge wealth of knowledge and experience contained within the Linux community, for some guidance. Now, I consider myself to be an experienced Linux user, but I've not had much exposure to large scale infrastructure, or real *sysadmin* tasks; I simply don't know your struggles, or the kind of workflow you have, and I want to learn.

I'm trying to take an old, stale, but still very useful tool called [omnissh](https://github.com/rykugur/omnissh), and design a more robust, concurrency-friendly version, which I've named [massh](https://github.com/DiscoRiver/massh). The idea is to be able to perform distributed shell commands to a vast number of hosts, concurrently, for the purpose of either executing tasks, or detecting inconsistencies in output.

The question I have for you, is, as an administrator of large distributed systems, what kind of feautres or behaviour would be useful for you, and what kind of information & feedback would be valuable when trying to run these kinds of commands?

Any information on what kind of things would be important to you when running something like omnissh, or massh, would be extremely useful to me. I appreciate anything you can offer.

Thanks!

If you haven't tried zsh give it a shot. I did today. I can't believe I haven't been using it.

Holy crap. It finally feels like a _modern_ terminal. Pretty sure you can do the same with bash but my god this just seems a leap forward for me. And there are so many awesome super easy to install customizations (I am using prezto its bomb).

Anyway just a quick PSA to all the folks here like me who haven't tried it. Might not be for you but I'm sure a lot of you will be like me today.

Linux existential cry for help. What do you do with Linux? Soliciting all the advice!

I have an obsession. It's Linux. Number 1, because it's free. Number 2, because it's freedom. I feel this is the correct ethos and should be self-evident in this group.

I cut my teeth in IT in the Marine corps as a Solaris sysadmin. After a tour, I went to a for-profit trade college and studied Information Systems Security, with emphasis on Windows enterprise.

I took contract work in the Bay area for a few years as Technical Support Analyst at a finance company and have been in various IT support roles in Windows and Mac environments.

I work at a private 7-12th grade school and have ample time to geek out on research and projects of work-related interests.

Which brings me to Linux.

I liked Solaris a lot \~20 years ago when I started but didn't think much about it. Cut to 10 years ago, I took Linux for a walk, had some trouble with GPU and wireless drivers, and put it on the back burner and stuck with Windows.

Over the last 5 years, Linux ISOs kept finding their way into my Downloads folder and all my extra USB drives (weird, right?), and my gaming rig was always running out of resources on account of poorly managed resources from abandoned VirtualBox VMs.

Then I learned Powershell for work and discovered the weird yet incredibly familiar command line environment, the love-child of Windows bat noscript and Linux. Holy shit, LINUX ALIASES in the Windows ($PS) command line? Old muscle memory comes back... LS instead of DIR?! YESSS. I'm hooked. I can't get enough, leading to picking up Linux again and putting it on as many old bare metal laptops I can find.

Cut to, "whoa, what's this Raspberry Pi thing? I'll take 4, please." "Raspian you say?" Let's do this.

Me roughly 3 years ago: "I should become a developer." Fuck it; I go all in. "Honey, I'm going back to school to get a degree in programming." It's been 3 years and I'm barely getting into the major-related coursework in C++. It's been a slog at one class a semester but it’s still interesting and feels relevant.

Me lately: "oooooh, what's this Arch all about... oh, this is, complicated."

But I've hit a wall and need some advice. I LOVE the process of Linux, from torrenting ISOs, to making them run on the crappiest hardware, to \*trying\* to successfully build vanilla Arch over and over until it's muscle memory, and making custom bash noscripts to set up my tools on a new install. It's all super enjoyable, but as a dad of young children who doesn't game anymore AND goes to school, I'm starting to ask myself what's next beyond the challenges of getting it installed. As a Windows admin, I can't switch to Linux at work, but could certainly do it at home if forced to (Ubuntu 19.10 has been a SUPERB laptop OS), and I could use Visual Studio Code if I needed to for C++ homework. I'm sure I could learn to deploy it in a homelab environment, but that seems like a lot to learn that I'd forget pretty quickly without re-enforcement from real life application.

I've dabbled in cloud stuff and micro services and have felt the "call" to build a website/web app, but web stuff feels like such a morass of potential security vulnerabilities that it scares me away from finishing any tutorials.

Fellow nerds of reddit, please weigh in and tell me what you use Linux for.

Please and thank you. The floor is yours.
