new install to-do list

this post is a work in progress:

after installing slackware, things to do besides the normal setup like configuring network card:

copy ssh keys from old install
copy /etc/sshd config?
copy .bashrc from old home install or the entire home directory
user groups review? (seems like its no longer needed under Slackware 14.2)
xorgsetup ? only if needed
compat32
libreoffice ?
wine?
firefox 40 (yes I stick to this version until Firefox can fix newer versions problems).


kde: fix nasty konsole prompt, edit Shell: /bin/bash -l

Installing PHP 7 from source

this post assumes you are familiar with Slackware 14.2 and have php 5.6 installed

1. Donwload php from sources, and extract it
2. inside the sources, create a script with this code or copy/paste on bash:
   

   #!/bin/bash
   ./configure \
       --with-config-file-path=/etc \
       --with-config-file-scan-dir=/etc \
       --enable-mbstring \
       --enable-zip \
       --enable-bcmath \
       --enable-pcntl \
       --enable-ftp \
       --enable-exif \
       --enable-calendar \
       --enable-sysvmsg \
       --enable-sysvsem \
       --enable-sysvshm \
       --enable-wddx \
       --enable-intl \
       --with-curl \
       --with-iconv \
       --with-gmp \
       --with-pspell \
       --with-gd \
       --with-jpeg-dir=/usr \
       --with-png-dir=/usr \
       --with-zlib-dir=/usr \
       --with-xpm-dir=/usr \
       --with-freetype-dir=/usr \
       --enable-gd-jis-conv \
       --with-openssl \
       --with-pdo-mysql=/usr \
       --with-gettext=/usr \
       --with-zlib=/usr \
       --with-bz2 \
       --with-apxs2=/usr/bin/apxs \
       --with-mysqli=/usr/bin/mysql_config \
       --with-ldap \
     --with-libdir=lib64

   edit: the long line from above as one line:
   ./configure --with-config-file-path=/etc --with-config-file-scan-dir=/etc --enable-mbstring --enable-zip --enable-bcmath --enable-pcntl --enable-ftp --enable-exif --enable-calendar --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-wddx --enable-intl --with-curl --with-iconv --with-gmp --with-pspell --with-gd --with-jpeg-dir=/usr --with-png-dir=/usr --with-zlib-dir=/usr --with-xpm-dir=/usr --with-freetype-dir=/usr --enable-gd-jis-conv --with-openssl --with-pdo-mysql=/usr --with-gettext=/usr --with-zlib=/usr --with-bz2 --with-apxs2=/usr/bin/apxs --with-mysqli=/usr/bin/mysql_config --with-ldap --with-libdir=lib64
   
   
3. make
4. make test
5. su
6. make install
7. edit /etc/httpd/mod_php.ini and comment lib_php5.so line
8. rc.httpd restart

running ATEM Software Control under Slackware

while this blog has a foolproof method for ubuntu, I believe I took a shortcut and managed to make it work under wine32 because you don't really need to install it to make it work, just like old fashioned software. Besides: installing wine64 just to install ATEM and then install win32 to run it sound more like a hack than a "propper" solution.

In case you dont have it already installed wine:
http://www.slackware.com/~alien/slackbuilds/wine/

1) on a Win setup, make a copy/compressed file of ATEM Software control
2) copy/decompress it on a Slackware box

then cd to the "Blackmagic Design/Blackmagic ATEM Switchers" and do

$ regsvr32 BMDSwitcherAPI.dll 

because if you dont the software will complain for missing DLLs.

and then you can run it:

$ wine ATEM\ Software\ Control.exe

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
