Iptables real world scenarios?

Fri, 2018-10-19 05:50

I know Iptables but never actually needed to implement them. Can someone give me any real time scenarios where iptables are useful. Maybe something you have done in your environment for a specific purpose?

What does this command do

Fri, 2018-10-19 05:10

what does sudo apt install -f do? I know it resolved dependencies error but what does the '-f' flag do? I find this subreddit to be fitting to ask.

Hung-up fuse filesystem prevented me from opening a sudo shell (with workaround)

Fri, 2018-10-19 04:26

This morning I mounted a remote borg backup and the filesystem process became unresponsive. This is not my first time dealing with a messed up fuse filesystem so I thought "no problem, I'll sudo -s, kill the process and fusermount -u the mountpoint". But I've recently pimped out my shell prompt (with powerline) and apparently, part of the startup process was getting stuck because of the hung-up filesystem.

I stood there for a while not knowing what to do and then I came up with a cool workaround. I ran sudo python instead, used a non-root terminal I already had open to grep for the offending PID and then did import os; os.kill(pid, 9) and that gave me my system back.

Not a huge deal, I know. But I felt like sharing it with a like-minded community.

Are there plans for making WPS Office open-source? At least the community version.

Fri, 2018-10-19 03:07

At least in something like the open source version of Qt.

I don't know if it's because it's been a good amount of time that I am far from the Windows environment with freeware programs, but I am of the opinion that the software either must be a paid proprietary software or be open sourced once and for all. I hate the possibility in getting "dependent " of a gratis software that suddenly become a paid software. It's just my opinion.

I've noticed that grep doesn't always affect the target file's access time as shown by "ls -lu". How is the access time determined?

Fri, 2018-10-19 02:53

Even in files where grep finds what it's looking for, the access time of that file is not always affected. Try it to see what I mean. Does anyone know why?

What commonly installed program on Ubuntu accesses seemingly random files at seemingly random times?

Fri, 2018-10-19 02:23

I see the accesses with "ls -lu" even for files I haven't used in a long time. And it's not all the files in a directory at the same time, but several of them at a time.

WSL vs dual boot

Fri, 2018-10-19 01:30

I need to use unix shell to run some programs for my studies (computer science, the course is about "high performance computing"), but on my laptop I use Windows 10. I tried using the WSL, and the result seems to be quite sad: the program started at 2:15 PM and it's still running; a friend of mine launched it in some hours after me (on dual boot and with a "worse" CPU) and it already finished.

If you need, I can be more specific about the code I'm running and on my laptop specs.

Ubuntu on Vbox being too slow.

Thu, 2018-10-18 23:59

I recently downloaded a copy of Ubuntu 18 LTS , and installed in Vbox with the configuration given below.

Ram - 4 GB ( allotted to guest OS Ubuntu , host has 8gb ram )

Video memory -128mb ( highest i can allot )

Processors - 1 ( chose 2 and then 3 processors but it was slow then as well )

Pae/nx enabled

Swap memory - 4gb ( primary boot partition - 57 GB )

The animation of windows is super slow, minimizing a win takes 4-5 sec , sometimes it just hangs.

It was a simple installation with only Firefox and some necessary tools. Is there anything I can do ? Has anybody else encountered the issues before.

I have thought of removing gnome fully and use unity as default GUI . Will that help ?

I haven't installed Nvidia graphics card drivers , do they in any way increase my performance ?

Or should i move to Lubuntu or Ubuntu mate.

Will every piece of software that works in ubuntu work in Lubuntu ( i am installing ubuntu for my rails dev , so i don't want to compromise on my performance). If not , will adding the repository links of ubuntu help in that?

Ps - I am open to any suggestions recommending me to opt out for another os , as long as it can support most of the programs i can run on ubuntu.

Sorry , i am beginner so these questions might not make sense !

Ubuntu User statistics

Amount of Linux users / distro

Thu, 2018-10-18 22:22

I was wondering if there are good statistics about the usage of Linux distributions on the desktop. I found some articles saying that 0.5% - 1.5% of desktop computers runs Linux. Let's say it's 1%

I'm wondering about the usage of different distributions, how much of those computers run Ubuntu, Fedora, OpenSuse, Arch, Elementary, Debian, ... I think most Linux desktops will run Ubuntu, but can't find any numbers (it might be a language barrier, English isn't my first language).

On the low adoption of automated testing in FOSS

Thu, 2018-10-18 20:51

For projects of any value and significance, having a comprehensive automated test suite is nowadays considered a standard software engineering practice. Why, then, don't we see more prominent FOSS projects employing this practice?
