  • If you'll be given the chance to test your country's next Presidential candidates, what would it be and why?

  • I thought rise of fascism was mainly reponsibility of people who vote for fascists and candidates who have nothing to suggest to fight fascism and make people lives better but I guess I was wrong.

  • Study finds smartphone bans in Dutch schools improved focus

    Jump

  • This is not a demonstration and this does not qualify as a scientific proof. 🤷

    They polled teachers. It ir like I polled religious and conclude that God exists because God speaks to most of the people I polled. This is not science, sorry not sorry.

  • Yeah, except science does not work like that. 😐

  • 1312 is the best PIN code tbh.

  • Quel contenu voudriez-vous voir sur Peertube ?

    Jump

  • Peut-être demander dans le sujet de discussion du forum libre ou créer un sujet parce qu'en commentaires ici, je pense que beaucoup de monde ne verra pas la question !

  • Quel contenu voudriez-vous voir sur Peertube ?

    Jump

  • Je pensais à des types de contenus et non des miroirs (ou migrations) de chaînes YouTube. Du coup plutôt du contenu sciences/vulgarisation ?

    Why am I having back pain nowadays after peeing??

    Jump

  • I've had kidney stone, they would be on the floor already, calling emergencies. It is not only after peeing.

  • J'ai fait appel à une artiste pour peindre mon mur sur le thème de Arcane

    Jump

  • J'y ai pensé mais à part sa page BookAnArtist, je n'ai rien. Je voulais lui demander si elle a un site ou autre mais je n'ai pas eu l'occasion encore (et je pense que la réponse est non).

  • C'est mon bureau. Je suis en télétravail total alors j'ai voulu me faire plaisir. Quand le travail me gonfle, je peux me retourner et regarder le mur ! 😊

  • What was the strangest reason you got in trouble in school?

    Jump

  • It may not be the strangest, but it shows how some teachers just don't like you personnally for no reason. I don't know the English grade system so I was around 14-15yrs old I'd say. Drawing teacher gave me 2 hours of detention which I didn't know (I learned it because I stood in school as my parents couldn't take me early). So I learned that, I had an exercise to draw again the same exercise because my previous drawing was "bad" and he thought I didn't spend enough time on it. Surprise, the girl who has had the greatest grades in art, and happened to be my friend, suggested to draw it for me. So I said yes and she drew for me, I didn't do anything.

    I gave that back to the teacher, he did not even gave me 10/20 (that's how grade works here). So I had a bad grade, I don't remember exactly but he said I had not worked enough as habits.

    Bastard.

  • Smoking should be banned. Full stop. When my neighbours smoke I can't even open my window, I have asthma. The smell attaches to the walls. There is also my kitchen where I cook and I can't enjoy my little place outside because it constantly smells cigarette because they smoke regulary.

    1. Supervise command (run every 2s)

     
        
watch "ls -larth"

    1. Kill program using one port

     
        
sudo fuser -k 8000/tcp

    1. Limit memory usage for following commands

     
        
ulimit -Sv 1000       # 1000 KBs = 1 MB
ulimit -Sv unlimited  # Remove limit

    1. Rename selected files using a regular expression

     
        
rename 's/\.bak$/.txt/' *.bak

    1. Get full path of file

     
        
readlink -f file.txt

    1. List contents of tar.gz and extract only one file

     
        
tar tf file.tgz
tar xf file.tgz static

    1. List files by size

     
        
ls -lS

    1. Nice trace route

     
        
mtr google.com

    1. Find files tips

     
        
find . -size 20c             # By file size (20 bytes)
find . -name "*.gz" -delete  # Delete files
find . -exec echo {} \;      # One file by line
./file1
./file2
./file3
find . -exec echo {} \+      # All in the same line
./file1 ./file2 ./file3

    1. Print text ad infinitum

     
        
yes
yes hello

    1. Who is logged in?

     
        
w

    1. Prepend line number

     
        
ls | nl

    1. Grep with Perl like syntax (allows chars like \t)

     
        
grep -P "\t"

    1. Cat backwards (starting from the end)

     
        
tac file

    1. Check permissions of each directory to a file

    It is useful to detect permissions errors, for example when configuring a web server.

     
        
namei -l /path/to/file.txt

    1. Run command every time a file is modified

     
        
while inotifywait -e close_write document.tex
do
    make
done

    1. Copy to clipboard

     
        
cat file.txt | xclip -selection clipboard

    1. Spell and grammar check in Latex

     
        
detex file.tex | diction -bs

    You may need to install the following: sudo apt-get install diction texlive-extra-utils.

    1. Check resources' usage of command

     
        
/usr/bin/time -v ls

    1. Randomize lines in file

     
        
cat file.txt | sort -R
cat file.txt | sort -R | head  # Pick a random sambple

    Even better (suggested by xearl in Hacker news):

     
        
shuf file.txt

    1. Keep program running after leaving SSH session

    If the program doesn't need any interaction:

     
        
nohup ./script.sh &

    If you need to enter some input manually and then want to leave:

     
        
./script.sh
<Type any input you want>
<Ctrl-Z>          # send process to sleep
jobs -l           # find out the job id
disown -h jobid   # disown job
bg                # continue running in the background

    Of course, you can also use screen or tmux for this purpose.

    1. Run a command for a limited time

     
        
timeout 10s ./script.sh

    Restart every 30 minutes

     
        
while true; do timeout 30m ./script.sh; done

    1. Combine lines from two sorted files

     
        
comm file1 file2

    Prints these three columns:

     
            Lines unique to file1.
    Lines unique to file2.
    Lines both in file1 and file2.

    With options -1, -2, -3, you can remove each of these columns.

    1. Split long file in files with same number of lines

     
        
split -l LINES -d file.txt output_prefix

    1. Flush swap partition

    If a program eats too much memory, the swap can get filled with the rest of the memory and when you go back to normal, everything is slow. Just restart the swap partition to fix it:

     
        
sudo swapoff -a
sudo swapon -a

    1. Fix ext4 file system with problems with its superblock

     
        
sudo fsck.ext4 -f -y /dev/sda1
sudo fsck.ext4 -v /dev/sda1
sudo mke2fs -n /dev/sda1
sudo e2fsck -n <first block number of previous list> /dev/sda1

    1. Create empty file of given size

     
        
fallocate -l 1G test.img

    1. Manipulate PDFs from the command line

    To join, shuffle, select, etc. pdftk is a great tool:

     
        
pdftk *.pdf cat output all.pdf        # Join PDFs together
pdftk A=in.pdf cat A5 output out.pdf  # Extract page from PDF

    You can also manipulate the content with cpdf:

     
        
cpdf -draft in.pdf -o out.pdf      # Remove images
cpdf -blacktext in.pdf -o out.pdf  # Convert all text to black color

    1. Monitor the progress in terms of generated output

    Write random data, encode it in base64 and monitor how fast it is being sent to /dev/null

     
        
cat /dev/urandom | base64 | pv -lbri2 > /dev/null

# pv options:
#   -l,  lines
#   -b,  total counter
#   -r,  show rate
#   -i2, refresh every 2 seconds

    1. Find packages that have a given file in Ubuntu

     
        
apt-file update
apt-file search dir/file.h
