Is there a distro that just installs/werks on a UEFI laptop? I have a 2013 ultrabook and apparently I need to create an EFI partition using windows before I even need to install GNU?

Nah, you can just create the partition during the installation process.
As for the distro, I would suggest:

-Xubuntu if it's your first time trying linux and you want something friendly.
-Devuan if you want something very stable that won't break easily and doesn't have systemd.
-Void if you want rolling release without systemd and like ponies+hardly any documentation.

Linux newfag here. I''m thinking of installing Ubuntu, should I bother with the LTS or use 18.10. Or should I wait until 19.04.

>also why the hell does debian not have sudo installed by default on the fucking desktop version

why? its a clean install

what are some programs to have a minimum level of security on linux?

Debian suddenly isn't loading the window manager on login
what the shit

I'm trying to cut a video without reencoding it on ffmpeg

ffmpeg -ss 00:00:00 -t 00:12:41 -i '/home/User1/Videos/720 (24).mp4' -vcodec copy -acodec copy output.mp4

But I'm getting the error output.mp4: No such file or directory. What am I doing wrong?

Also how do I cut a part from the middle of the video, or have multiple cuts without reencoding?

Try adding your user to the "wheel" group.

Try moving the "-i input-video.mp4" before all the other options
>Also how do I cut a part from the middle of the video, or have multiple cuts without reencoding?
I'm not sure what you mean. Isn't that exactly what the snippet you just posted is supposed to do?

For the record, using the copy codec won't always give you perfect control over where the cut starts and stops. It can be off by a few seconds because it has to cut it on keyframes to avoid re-encoding.
If you need exact times you may have to re-encode.

Also, I usually use -c:v and -c:a instead of -vcodec and -acodec
I assumed they were the same thing since I've seen those before, but I'm not seeing them in the manpage so maybe that's your problem. I would try this command:
ffmpeg -i '/home/User1/Videos/720 (24).mp4' -ss 00:00:00 -t 00:12:41 -c:v copy -c:a copy output.mp4

It worked now

I mean if I want to cut off advertisements in the middle of a video.

>minimum security
Nothing, the system should be pretty solid as-is.
>good security
Configure the internet facing elements according to a guide. This includes tightening down sshd, activating the firewall, and privilege separations.
linode.com/docs/security/securing-your-server/
and others
>high security
Antivirus, AppArmor, SELinux, ACLs, kernel hardening. There's usually no need to bother with this stuff.

How the heck am I supposed to know what each of these is for?

How do I add a fade out effect to the last second of a video without changing anything else with ffmpeg?

So this is more of ricing question, but i need help with i3.
I want to change the title bar and borders of certain windows to a different color, but you can only specify the colors with client.active, client.inactive, etc. globally. Does anyone know how i3 works internally and maybe how to change the source to allow for specifying colors with for_window?

I installed vsftpd and it worked like a charm with self signed certificate and my domain. I recently modified the domain name so regenerated the certificate + modified the vsftpd.conf to reflect the change, but it no longer works. I can get to my machine, have the login prompt, but it gives me error 530, login incorrect.
I tried to reinstall it but same error
Everything I find talks about pam which I don't use or of a potential userlist that I have disabled anyway. Any idea ? It's driving me crazy to not find out what's going on

Best Skype alternative?

discord, but only ironically

I messed around with it a while back to add indicators for tabbed and stacking modes (to 1/3 or 2/3 the left and right borders as the "indicator" color depending on the mode)
It's been a while though, but my patch is in the file x.c. Skimming through it real quick I'd probably guess this is where you'd need to modify:
github.com/i3/i3/blob/next/src/x.c#L499

Although for the record you can already do something similar (pic related) without having to modify the code.

Jow Forums won't let me write it here

Thanks man.
I'm already doing the second option but it honestly looks like shit. I'll look into x.c later today. maybe I manage to not fuck it up.

I have a problem on a Mint machine, awhile after installation i cant update and it says that Firefox is running when its closed. After reboot it breaks and i need to run Fsck manually, anyone that can know why this keeps happening?

Hi anons i am in need of some help.
I am trying to add a route for between two VMs with a VM as a router(all of them are linux).
But when i try to insert the iproute i get a RTLINK:operation not permitted.
What am i doing wrong?

Oh wait i am a retard, a sudo solved everything.

How do I into ISCSI performance? Hyper-V stored on ISCSI freenas machine. The freenas zvol uses standard settings, LZ4 and standard zfs 16k block size. Should I set the ISCSI logical block size to that of ZFS (16k) or what windows will be using (4k).
For that matter, do you adjust the block sizes for the underlying storage or what hyper-v will be doing with it?

HAHA I DID FUCK YEAH
Am i hackerman yet?
god this was annoying
i am a total newbie so doing this was anooying as fuuuuck.

I heard some anons telling me to learn posix shell, so i went to search it, it seems its something not suported anymore? why should i learn it then?

It can produce verbise logs, try doing that. If that doesn't explain it, run it with strace or such.

You shouldn't. However writing shell scripts in fish or zsh dialect rather than bash will not make other people like you if they have to use them. Pretty much prfer even go, perl, python or even scala ammonite to these.

But that's only if you want to publish the scripts.

I see, so there is literally no advantage to learning it if i am not a open source contributing cuck?
Ok thanks!

oh, I thought it was by default and found them to be a little cheap on that. I'll try it.

Is there a way to easily create an audio recording on linux?
I have a small signal I am playing with my laptop, but I want to store it in a file.
How do I do that?
Parec doesn't seem to capture it, I don't know how to "play" my series of mp3 files correct, "play" and "mpv" doesn't do it.

I am not very good at coding so i tought about going
N=0
if n=0
sudo yum install myeggs
n=n+1
But then everytime it boots it would return N to 0 so it would be for naught, how should i do it?

You don't need to install the same package more than once.
What are you trying to do?

Try Audacity or something? I think you can also do it with pulseaudio or sox.

Its a script but vagrant will run it everytime i vagrant up a VM.
Is there anyway to limit it?

how do i make my laptop into a website server?

>>open port on your rooter

Docker

GLAMP stack.

what if i don't have access to the router

>I''m thinking of installing Ubuntu, should I bother with the LTS or use 18.10. Or should I wait until 19.04.

Use the current LTS

[me again] any free temporary vps?

POSIX is a set of rules on how things should work. A POSIX compatible shell such as bash must support specific rules. The benefit is that your shell script runs on all shells with POSIX compatibility; your POSIX bash script will run on zsh and vice versa. Another benefit is speed: many shells invoked as /bin/sh will run in a lightweight POSIX mode, making scripts execute faster.
However, bash is available everywhere as default shell, and it's easier to write a bash script than going through the pain of making it POSIX compatible and with the use of builtin shell features instead of external processes, you gain speed aswell.

tl;dr learn bash, then get some posix knowledge for cases when you want to publish a widely compatible script

Am I crazy or is my 2017 x1 carbon 7300u gotten slow as literal shit from all the meltdown/microcode patches. Trying to figure out if I need to reinstall my os or get a new laptop.

Variant 3 fix can rape your performance.
Download the spectre-meltdown-checker thingy and run it. It will tell you about it.

You might be interested in this.

how do I make a symbolic link to a directory that is a computer connected to the router (local network)?

you don't.
symlinks point to folders and files, not on network resources. Unless of course you somehow manage to mount the computer to a folder.

someone any similar problem with true transparency?

dumb ricer

it's fun

Oh shit I completely forgot about this thread.

Hey my fellow anons, I got a problem and created a thread earlier describing the problem.
Anyone got an idea?
What are the chances that changing the distro would fix that?

Try dicking around with the wifi module. You can load and unload it on the fly using modprobe. I've had to change a setting in iwlwifi back in the day in order to get better wifi. Maybe it works for you aswell. Ask your search engine.

I used Win10 for about a week holy shit FL Studio is not worth this much pain I'd rather sacrifice a little performance/plugin compatibility and use wine instead. I'm sorry /fglt/ bros I'll never do it again. (win7 is still good though).

I use Void btw™

I will try following this guide then tomorrow.

Do you think that might help or is that a trash site?

"win10privacy" can get rid of most of the "visible" cancer and annoying stuff if you really have to use windows.

Is there FOSS equivalent for OneNote?

nvm, misread manual
urxvt -e mpv

How do you guys handle off-site backups? As far as I can tell, there's no program or service that offers real-time backups.

doesn't just putting 'mpv' on the 'open with' thing work as well? you don't need the urxvt -e part I'm pretty sure

I leave an encrypted usb hard drive with somebody I trust and do not live with. Every few months I swap the drive out with my latest on-site backup, which becomes the new off-site.

Sensitive data that I'd hate to lose in a disaster is also copied to my phone in the meantime, which is always kept with me. The chances of something happening to my computer, my normal backup and my phone simultaneously is small enough that I don't think a solution beyond that is worth the cost/effort.

not in terminal emulator - launches gui
and using --force-window=no plays "in background"
using for audio files

Thanks for the answer. I really want a more frequent backup though. I couldn't stand something like losing several months of work if my place burned down. So the only option for that I see is encrypted cloud backups. It bums me out that there don't seem to be too many options for that, so I guess my best shot is something "standard" like duplicity maybe, scheduled hourly or something like that...

How do you find out the IP adress of devices connected to you computer throug WiFi or RJ45 port?

Debian i386 still ships with a non-PAE kernel you can use on stone age CPUs.

Note: if you can, boot up DSL on that bad boy, allocate partitions and create a swap partition that Debian installer can use asap.

This is unironically a case where recommending something like Tiny Core might be warranted.

32MB RAM is not going to get you anywhere with modern graphical applications.

>32MB RAM is not going to get you anywhere with modern graphical applications.
My OpenWrt router uses 28MiB, no GUI running of course. I think the only way to have GUI with 32MiB is to render it client side, e.g. using a web interface, which OpenWrt does with Luci.

What if the device doesn't use default IP?
Like what if the device IP is something like 10.122.45.2 who would you know that?
Let's assume the device is serving a web page on port 80.

Any suggestions for a DE that's similar to bspwm? I've been running into some issues getting polybar/keybindings/various other things to work. Nothing that can't be solved with a bit of work, but I've got a lot of deadlines approaching and for the time being, I want to switch to something more fleshed out that just works, while also feeling reasonably similar to bspwm.

Windows 3.1 was able to run on 1MB. It's clearly not impossible to have a GUI if you're running ancient, unsupported 90s stuff. Just stupidly obnoxious and not possible with modern applications.

is there some place where i can find some list of some cool themes and desktop enviroments or is it all just "scattered" over the internet

gnome-look.org for themes

I've installed Void, but for some reason I can't get nmtui to see any wireless networks.

Does anyone have any experience setting NetworkManager up on Void?
