Cemu has better performance on Linux through Wine than natively on Window$

Lately I have been playing around with cemu, and i saw [this guide](http://compat.cemu.info/wiki/Serfrosts_Cemu_Setup_Guide) suggesting that there is performance to be gained by switching to Linux, so I fired up my Manjaro installation, used [this noscript](https://github.com/CEMULinux/cemutil) and was playing just 5 minutes after that! (I already had the games dumped on another drive)

This really made a difference for me, as on windows I was averaging about 15/18 fps while being CPU bound by my x4 860k, while on Linux i get around 20/28 fps, with the occasional dip in the high 10-15s.

I think we should encourage the cemu team for their efforts, they have a patreon [here](https://www.patreon.com/cemu)!

Maybe we could even go as far as to push for a native Linux port (although the team is small, so it might be more feasible to get them to open source the emulator and fork it with linux support)

So I nuked my root directory

And I don't even know what I did wrong.

I had lots of files and libraries I wanted to put in another system, so what I decided to do was to make a directory in which I reproduced the filesystem hierarchy (/bin, /lib, /usr/bin, etc.), and placed all the files in those folders. I then, inside that directory, created a tarball containing those folders (tar -cvf files.tar *).

I moved that files.tar tarball to the root (/) of my target system, and extracted it there (tar -xvf files.tar). What I expected to happen was for all those files to be placed inside /bin, /lib, /usr/bin, etc. What actually happened is that those files were placed inside those folders, but also that *everything that was inside those folders before was deleted by tar*. So I have completely borked my system.

This might be the first time I do something this dumb, but it certainly won't be the last.

Is it possible (and useful) to enable Meltdown and Spectre mitigations only while browsing?

Hi. I was wondering if this is possible with a noscript? Could I run mitigations=on when my browser starts and runs mitigations=off when it closes? Because I really only worry about JavaScript with regards to those vulnerabilities.

Or since it's a kernel thing I would require a reboot to make things effective?

I am one complete newcomer and would like some guidance.

Thanks!

Looking for a tool that can virtually traverse an entire iptables chain stack (or one chain) in userland

I'm looking for a tool that can take a "packet object" and with it, virtually traverse an iptables chain or the entire iptables filter/nat/mangle stack. Using the TRACE target isn't what I'm looking for, as I need to test offline traffic (for example, replaying from tcpdump captures). Ideally, I should be able to specify incoming interface, L2 src/dst MAC, L3 src/dst IP, protocol, L4 src/dst ports, tcp flags, etc, and view the path the crafted packet takes through all the iptables rulesets, printing each matching rule.


I've seen people ask about something like this in the past, but nobody's asked recently, and nobody's gone back to those threads with new developments.


If this doesn't exist, is there a path to take the iptables/netfilter/conntrack code into a userland library and allow someone to inject crafted packets into it while showing match-logic debugging output?

Will changing a hard drive from an LVM volume system result in data loss?

I'm planning to build a NAS based on Proxmox with four 8TB disks and put it to use as my home NAS. As I don't want any capacity loss due to redundancy or parity, I've decided to create a logical volume from sda1\~sdd1. AFAIK, LVM would work like JBOD and write data consecutively from sda to sdd, so at least data that span two disks should be lost if one of the hard disks failed/got changed according to my understanding. However, there's plenty of articles depicting the method of changing hard disk(s) out there on the Internet, which really confuses me. Anyone can share any thoughts on that plz?

Language switch on GNOME?

Hi people. I'm on a remote farm in Serbia where I'm trying to set up a laptop for my good buddy Slaviča Maksimovic, so he can have foreign volunteers on his farm, because he needs it and loves it. <-- short version.

Slaviča doesn't speak English. I don't speak Serbian so I set up the computer in English (Ubuntu, regular). I'll soon switch it to Serbian so he can actually use it. But he'll run into issues instantly (prediction) and I'm going to need to do a lot of switching back and forth between Serbian and English to help him figure shit out.

Now, all my research about a quick language switcher points to keyboard layouts. But no, I need to be able to switch the system language quickly with maybe a menu entry between the Bluetooth menu and the battery menu. There can't not be something like that. Anyone?

Ubtuntu 19.04 - nVidia 340.107 drivers broken

I have a GeForce 210 GPU in my home server. It has very low TDP which is why I bought it in the first place. However, nVidia legacy 340.107 driver package does not currently work for Kernel 5. The package fails to compile. I saw a user made a patch but I have no idea how to apply it. Has anyone dealt with this and found a fix?

&#x200B;

Failing a possible fix, a possible GPU recommendation would be appreciated. The server has a desktop for web browsing but mainly exists as a Plex Media Server transcoding video. Running i7 Nephlam 920, 8GB DDR3 and the GeForece GT 210 card currently.

&#x200B;

Any help is appreciated.

Git-logger - A classic git punch-card in your terminal!

Hi,

&#x200B;

[Git-logger](https://gitlab.com/CrazyBaboon/git-logger) is a 160 line Bash noscript that replicates the git punch-card that was once available on Github - and it runs in your terminal :)

&#x200B;

The initial release was in 2018, but it had serious limitations when baking large projects. Hopefully these have been solved!

&#x200B;

Here are a few screenshots:

&#x200B;

This new version of git-logger bakes the Linux project (quite large) in around 10 sec (Intel i7-2600):

And, as an example of a small project, here is [Feynman](https://gitlab.com/CrazyBaboon/Feynman):

https://i.redd.it/ookb5jikkca31.png

Simply copy the noscript **git-logger.sh** to the target git folder ([GIMP](https://gitlab.gnome.org/GNOME/gimp) for example) and type:

./git-logger.sh

&#x200B;

&#x200B;

Feedback is greatly appreciated! I hope you enjoy this tool!
