Things to know about the Line6 DL4 looper

Line6 DL4 it's an amazing pedal, the delay sounds and even the modulation effect is amazing, but if you are thinking of buying it mainly because of it's looper functionality then you need to know the following things that no one seems to mention:
  • Loop mode it's not true bypass and you'll hear your tone a little darker in this mode.
  • You can't use the delay modelers while on Looper mode, you can only use an echo provided with a few parameters to configure that you can't activate or deactivate with your feet.
  • You can't access looper mode while on stomp mode with your feet without modifications to the unit.
  • Your loops are not stored. If you go to stomp mode or you turn off the device your loops are lost for ever.

If you're cool with that you won't regret of getting this pedal.

Paramore Moving on - cover

This cover was played and recorded in one take with an android phone. Some eq. and reverb was added in Ardour DAW.

Not bad for the small amount of time invested.

Enjoy!

Check if 2 binary files are exactly the same in linux


By comparing the md5sum of two files you can tell if those files have the exact same content or not.

Let's make a quick script:

1
2
3
4
5
#!/bin/bash
md5sum $1 | cut -d' ' -f 1 > /tmp/j
md5sum $2 | cut -d' ' -f 1 > /tmp/k
 
diff -y /tmp/j /tmp/k

#!/bin/bash
md5sum $1 | cut -d' ' -f 1 > /tmp/j
md5sum $2 | cut -d' ' -f 1 > /tmp/k

diff -y /tmp/j /tmp/k

And then we can call it like this diffScript.sh bin1 bin2, where bin1 and bin2 are two files that we want to compare.

View binary file as hex in linux terminal - xxd

Straight from the man page:

 xxd  creates a hex dump of a given file or standard input.  It can also convert a hex dump back to its original binary form.

So a simple xdd file will output something like this:


Add -b flag for getting binary output instead of hex, -i flag to output as C include file style.

KDE network manager not remembering wpa password

I'm using Kxstudio on my desktop PC and it's great for my purposes, I highly recommend Kxstudio for home studio enthusiasts.
But there was a little problem that bugged me from the beginning, and that is that for some reason, the NetworkManager applet would not remember my wpa password.
Every time I turned on the PC I would have to enter the password manually, and that's a real pain with a 35 character password.
nmcli to the rescue!
Add the following line to a file called connectWifi.sh
#!/bin/bash

sudo nmcli dev wifi con "My essid" password my_long_passphrase name "My connection name"
Then make the file executable with the following command
$ chmod +x connectWifi.sh

Then  we add this command to the sudoers file so that we don't have to insert a password every time we use nmcli.
Open the sudoers file with the following command:
$ visudo
And then add at the end of the file the following line:
youruser ALL=(ALL:ALL) NOPASSWD: /usr/bin/nmcli
Replacing youruser with your linux user name.


Finally we add the script to the autostart window located at SystemSettings -> startup & shutdown -> autostart -> Add Script... and navigate to the script file.



And that's it!
