How to ask for root password when using sudo

A minimal improvement to your security is asking for a password when you allow normal users to execute privileges command via sudo. Usually, they just type their own password and that allows they to gaing privileged status to execute what you have set in sudo files.

You should consider change this behaviour and ask for root password. Why? it’s too easy IMHO to execute a root command because the user (or impostor) only needs to know one single password and not your root password but someone elses one.

Instead of that setting I prefer to change sudo files to this in the /etc/sudoers:

Defaults rootpw

Before do that, be sure your root password is setted and accomplish a minimul security recommendations. It will not apply in current shells, but the new ones.

Why I remove the AddThis plugin?

I’ve being using the AddThis plugin in WordPress for a quite time. I’ve have decide to eliminate it for coherence reasons.

I started to use Privacy Badger in Firefox and I realize that the AddThis give a way to make easy to share the posts I wrote but the payment is (as many others things that are for free in the Internet) they collect information about the people browsing this site, no matters if the post is shared or not.

So, as long as I’m Free Software Foundation Europe supporter (consider collaborate with FSFE) and I’ll found myself better if erase it. This are my two cents to improve your and my privacy.

Dropbox on its own datacenter

I wrotte in 2015 about Microsoft will buy Dropbox, was I wrong?

Yes and not. There were a serious threat for Dropbox according its depence from Amazon and, and that time, there were doing things togheter with MS that pointed easily to a possible adquisition.

The changes came from both companies; Microsoft started a strong positioning towards Cloud market and Dropbox started to take off from Amazon its infrastructure. Dropbox goes public and economical argues become more and more important. The truth affects both lines: going public and on the other hand keep themselves independent on its own datacenter. They both go togheter.

Why am i going to “play” with a Rasperry Pi? (Update 31/03/2018)

Why am i going to “play” with a Rasperry Pi? Short answer; for educational purposes.

No the little bit more explained why I decide to sset up a Rasperry Pi, but also going to the point:

  • I’m very bad with hardware, so it’s a little bit challenging for me
  • a very good friend gift me its Raspberry Pi 1 (512Mb RAM) and it was collecting dust
  • I may obtain something useful at the end of the process, for instance, a media server, a little NAS, whatever.
  • I’m going to refresh my former sysadmin skills; file system formatting, installing different OS’s flavours, setting up a network, etc.
  • It’s a wide documented process so it keeps my attention in making the right thing, not in solve a new problem never before seen.

So, again, for educational purposes, mixing up fun with refreshing basic skills.

Update 31/03/2018:
Raspian up & running on an Raspberry Pi 1 model. Reasons for Raspbian:

  • Main reason: It forces me to get out of my usual Red Hat / CentOS / Fedora distro to a Debian based one. I hope this helps me in a future for getting the LP1 Certification
  • General purpose (I’m not looking for a particular functinality), I’m satisfied if it acts as a ssh gateway to the rest of home network
  • Well documented, this is a must since learn something new requires make mistakes. For example, I bought a USB – WiFi here you got how seting WiFi up via the command line, because command line always teches more than graphical interfaces IMHO

Jonh Perry Barlow y sus 25 consejos para una vida adulta

John Perry Barlow ha fallecido, fue fundador de la EFF – Electronic Frontier Foundation. Ahora es bastante desconocida en el mundo informático y entre las personas más jovenes, pero recomiendo conocer qué ideas animan la fundación y quién era John Perry Barlow así como otras figuras del momento.

Me conformo con recordar los 25 consejos de John Perry Barlow para una vida adulta (fuente Lifehacker) .

No estoy del todo en sintonía con alguno pero valen la pena. Es un ejemplo de que la tecnología debería estar al servicio de las personas; el hombre es la medida de todas las cosas.
