ffmpeg dynamic audio normalization

ffmpeg -i input.m4a -filter:a loudnorm output.mp3

Stylish for TW

For this recipe to work, you will need installed Firefox version 40-48, and Stylish Addon for Firefox.

The following template allows you to right click on an image in order to view it on a new tab or to save it as file, it also removes Moments and Who to follow.

@namespace url(http://www.w3.org/1999/xhtml);

@-moz-document domain("twitter.com") {
#above-timeline-prompt,
.moments,
.translate-button, .GalleryNav,
.js-recommended-followers
{ display:none !important }

}

Stylish for lanacion

 removes annoying header with alpha channel

@namespace url(http://www.w3.org/1999/xhtml);

@-moz-document domain("lanacion.com.ar") {
.anexo , #cabezal
{ display: none !important }

body header#cabezal.transparente + .storytelling::before
{ background: white; height: 0 !important }

}

ffmpeg conversion from h265 to h264

some strange reason, lastest version of VLC doesn't work very well under Slackware. I got sick tired of it and decided to go back to 2.0.7. But a problem arise when I want to watch a video encoded with h265. So I ended up converting them to h264 using a simple command line.

#!/bin/bash

for file in *.mkv
        do ffmpeg  -n -i "${file}" -map 0 -c:a aac -c:s copy -c:v libx264 264/"${file}"
done

Global Stylish for Firefox

Specially imporant when you have a dark theme as desktop in KDE and when Firefox or a web page does not handle all colors properly

@namespace url(http://www.w3.org/1999/xhtml);

input
{ background: white ; color: black !important }
select
{ background: white ; color: black !important }

Funny thing about this is: under Firefox 45 it changes default colors for address bar and search bar.

UnHook EXE

This can be useful when a trojan or virus replaces registry entries for executable files with a custom one.

slackware 14.2 bashrc

Slackware 14.2 has many changes since version 14.0. So far the most annoying to me is the prompt under console and the ls colors.  So I figured I should copy/paste the definitions from 14.0 into a .bashrc

#!/bin/bash
export PATH=$PATH:/home/rudy/bin
export PS1='\u@\h:\w\$ '
export LS_COLORS='no=00:fi=00:di=01;34:ln=01;36:pi=40;33:so=01;35:do=01;35:bd=40;33;01:cd=40;33;01:or=40;31;01:su=37;41:sg=30;43:ca=30;41:tw=30;42:ow=34;42:st=37;44:ex=01;32:*.bat=01;32:*.BAT=01;32:*.btm=01;32:*.BTM=01;32:*.cmd=01;32:*.CMD=01;32:*.com=01;32:*.COM=01;32:*.dll=01;32:*.DLL=01;32:*.exe=01;32:*.EXE=01;32:*.7z=01;31:*.ace=01;31:*.ACE=01;31:*.arj=01;31:*.bz2=01;31:*.cpio=01;31:*.deb=01;31:*.dz=01;31:*.gz=01;31:*.jar=01;31:*.lzh=01;31:*.lzma=01;31:*.rar=01;31:*.RAR=01;31:*.rpm=01;31:*.rz=01;31:*.tar=01;31:*.taz=01;31:*.tb2=01;31:*.tbz2=01;31:*.tbz=01;31:*.tgz=01;31:*.tlz=01;31:*.trz=01;31:*.txz=01;31:*.tz=01;31:*.tz2=01;31:*.xz=01;31:*.z=01;31:*.Z=01;31:*.zip=01;31:*.ZIP=01;31:*.zoo=01;31:*.aac=01;35:*.AAC=01;35:*.anx=01;35:*.asf=01;35:*.ASF=01;35:*.au=01;35:*.axa=01;35:*.axv=01;35:*.avi=01;35:*.AVI=01;35:*.bmp=01;35:*.BMP=01;35:*.divx=01;35:*.DIVX=01;35:*.flac=01;35:*.FLAC=01;35:*.gif=01;35:*.GIF=01;35:*.jpg=01;35:*.JPG=01;35:*.jpeg=01;35:*.JPEG=01;35:*.m2a=01;35:*.M2A=01;35:*.m2v=01;35:*.M2V=01;35:*.m4a=01;35:*.M4A=01;35:*.m4p=01;35:*.M4P=01;35:*.m4v=01;35:*.M4V=01;35:*.mid=01;35:*.midi=01;35:*.mka=01;35:*.mkv=01;35:*.MKV=01;35:*.mov=01;35:*.MOV=01;35:*.mp3=01;35:*.MP3=01;35:*.mp4=01;35:*.MP4=01;35:*.mp4v=01;35:*.mpc=01;35:*.MPC=01;35:*.mpeg=01;35:*.MPEG=01;35:*.mpg=01;35:*.MPG=01;35:*.nuv=01;35:*.oga=01;35:*.ogv=01;35:*.ogx=01;35:*.ogg=01;35:*.OGG=01;35:*.pbm=01;35:*.pgm=01;35:*.png=01;35:*.PNG=01;35:*.ppm=01;35:*.qt=01;35:*.ra=01;35:*.RA=01;35:*.ram=01;35:*.RAM=01;35:*.rm=01;35:*.RM=01;35:*.spx=01;35:*.svg=01;35:*.svgz=01;35:*.tga=01;35:*.TGA=01;35:*.tif=01;35:*.TIF=01;35:*.tiff=01;35:*.TIFF=01;35:*.vob=01;35:*.VOB=01;35:*.wav=01;35:*.WAV=01;35:*.wma=01;35:*.WMA=01;35:*.wmv=01;35:*.WMV=01;35:*.xbm=01;35:*.xcf=01;35:*.xpm=01;35:*.xspf=01;35:*.xwd=01;35:*.XWD=01;35:*.xvid=01;35:'
