timeline project minimum viable product

It's done: putting foreach loop in the correct place, and one flag variable to display one event to left and the next to right. And drawing the small blue point for each event using PDO connection to database. 
This is the output:

tlmgr Couldn't set up the necessary programs

Compilador: TeX Live 
(lo he obtenido haciendo sudo apt install texlive-full en Debian) Mala idea: el desfase entre el paquete y el CTAN puede volver obsoleto lo que tienes instalado. How to install "vanilla" TeXLive on Debian or Ubuntu?
IDE: TeXStudio

(no recuerdo cómo demonios obtuve la versión en castellano ¿problemas con el alemán?)

Algo salió muy mal, pues no hice nada después de la instalación, ni unas líneas de prueba con un archivo.tex, mucho menos alguna configuración.

Ahora ni siquiera puedo cambiar el tamaño de hoja (aunque parece que TeXStudio sí lo tiene a Letter):

$ sudo tlmgr paper letter

(running on Debian, switching to user mode!)
Cannot determine type of tlpdb from /root/texmf!
cannot setup TLPDB in /root/texmf at /usr/bin/tlmgr line 5713.

$ sudo echo $PATH

$ whereis texlive

$ ls /usr/share/texlive

passing variables using a href tag through foreach loop

Discarding security issues, this works for me:

SOLVED ntfs not configured in kernel

Can't use external hard drive in Oracle Linux 7.

Error mounting /dev/sdb1
EXT: Filesystem type ntfs not configured in kernel

So, this made my day:

1. How to Enable EPEL Repository for RHEL/CentOS 7.x/6.x/5.x, only I switched zabbix for ntfs-3g

2. How To Mount External Hard Drives In Linux, this is not relevant, I picked another name to device: /mnt/win

3. After reboot, File Manager in Gnome 3 showed nothing in EXT Toshiba (!). So, this was useful: How To Mount External Hard Drives In Linux - How To Add Items To The Fstab File In Linux.

4. Reboot

It works!
