Not an Ubuntu Topic, but a Humanity Towards Others

Hi, I'm completely sorry to publish this article in the Ubuntu planet, as it's not related to any Ubuntu Topic.

I'm writing to you, requesting your help for one friend, coworker, Laura Cano. She has been indirectly involved in our Ubuntu Honduras Team. (She did the proof reading of our English articles).

She is currently fighting Acute Lymphoblastic Leukemia for the second time. In order to recover she needs a bone marrow transplant. Unfortunately, this procedure is not done in Honduras. Meaning she would have to go abroad to get the transplant done as well as looking for a donor, getting the proper medical examinations, and other expenses. She cannot afford any of these because she is still recovering economically from the first episode.

If you will like to help Laura please feel free to do so: https://www.gofundme.com/laura-cano-medical-fund or sharing this link to your friends will be of great help!

As I mention at the beginning, this is not an Ubuntu Topic, but as the meaning of Ubuntu is Humanity Toward Others, we can help any way to this cause.


PS. If this post violates the policies of the Ubuntu Planet, please let me know, so we can remove it and prevent any issue.

Find which devices are connected to our network

Sometimes, we want to know how many devices are connected to our network. With any Unix OS you get easily know this. For this small tutorial we´re going to use Lubuntu 16.04.

We will use nmap. Nmap (Network Mapper) is a security scanner. It is used to discover hosts and services on a computer network.

For installing it, we first do

sudo apt-get install nmap

If we just need to identify the host names

 sudo nmap -sL
 The result of this command will be

Starting Nmap 7.01 ( https://nmap.org ) at 2016-10-02 12:39 CST
Nmap scan report for
Nmap scan report for
Nmap scan report for
Nmap scan report for
Nmap scan report for
Nmap scan report for

If we need to know the OS of the devices we have connected we do a:

sudo nmap -O
The address depends of your network, you should do a ifconfig for knowing yours.

The result of this command will be something like this:

Nmap scan report for
Host is up (0.0026s latency).
Not shown: 995 closed ports
22/tcp   open  ssh
80/tcp   open  http
3000/tcp open  ppp
3389/tcp open  ms-wbt-server
8080/tcp open  http-proxy
MAC Address: 6C:EC:EB:A5:38:5D (Texas Instruments)
Device type: general purpose
Running: Linux 2.6.X|3.X
OS CPE: cpe:/o:linux:linux_kernel:2.6 cpe:/o:linux:linux_kernel:3
OS details: Linux 2.6.32 - 3.10
Network Distance: 1 hop

 If you will like to read more about nmap, you can do a

man nmap

Using the calculator in the terminal

Hi to all, this is a small issue I had the last days. Use a calculator in the terminal. I have been working and sometimes need to do an arithmetic operation so I decided to open  calc (Ubuntu Calculator Default). But I was wondering, there has to be a way to use a calculator in the CLI. So after some search in the engine I found this question in Ask Ubuntu and tried several options.

I will only write about the  best solution I found for my needs. In the question, you can find several solutions and probably you will find a different solution that will be best for you.

CALC (Arbitrary precision calculator)

Calc is an arbitrary precision arithmetic system that uses a C-like language. Calc is useful as a calculator, an algorithm prototyper and as a mathematical research tool. More importantly, calc provides one with a machine independent means of computation. Calc comes with a rich set of builtin mathematical and programmatic functions.

If you want to install calc you can use the following command:

sudo apt-get install apcalc

Somos soñadores y no ganadores

Este 13 de Agosto del 2016 de mala suerte no ha tenido nada. Después de llevar una clase toda una mañana sobre manejar los conflictos en proyectos ágiles, sentarme y pasar a papel una idea que ya días estaba en la cabeza, la clasificación a semifinales de la selección olímpica me puse a pensar que nosotros los hondureños no somos personas ganadoras. Son pocos o nulos los triunfos a nivel internacional que tenemos, en deporte, ciencia, arte, etc. Pero hay algo que todo catracho tiene. Es un soñador.  Siempre tiene una sueño que seguir, y si se propone lo logra. El problema es trabajarlo, luchar por el, pero si logra superar eso, nadie nos detiene.

Les comparto este pelicula: La Meta de Eliyahu Goldratt
Una pequeña pelicula como muestra los procesos de mejora continua, como una persona lucha por un sueño, que es evitar que cierren la fabrica que el administra,
