Central America is discovering BeagleBoard!

The title is clear enough! I was on the VI Encuentro Centroamericano of Software Libre and gave a presentation about what is Beagleboard.org and showing some small demos of the BeagleBone Black.

Important refereces about Central America and Open Hardware/Single Board Computers & Microcontrollers

All of this data is according to what people said on Panama.
  • Arduino it's used in 6 countries of Central America as part of their computer science studies or electrical engineer
  • Raspberry Pi is also use on the 7 countries of Central America
  • Just 2 countries of Central America have listen about the BeagleBone Black. (Costa Rica & Honduras)
  • Just 1 country of Central America has work with a BeagleBone Black. (Honduras)

What was my talk about?

Basically my talk was about, what is the Beagleboard.org community and the Beaglebone Black.

  • I will said it again, people love it!
  • They were surprise about the bonescript library,
  • That's basically one of the major problems of other platforms. How to involved Web with Hardware platform.
  • The University of Costa Rica will buy BeagleBone Blacks for next years. (They have listen about the project and were interested on it, but didn't knew about all the capacities it had)
  • Some professors of Panama universities were quite happy to see that they could use this tool on their courses, this is thanks to the bonescript library, it is now easy to request project involving web applications and hardware combined thanks to the BeagleBone Black.

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 192.168.0.1/24  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 192.168.0.0 Nmap scan report for 192.168.0.1 Nmap scan report for 192.168.0.2 Nmap scan report for 192.168.0.3 Nmap scan report for 192.168.0.4 Nmap scan report for 192.168.0.5 If we need to know the OS of the devices we have connected we do a: sudo nmap -O 192.168.0.1/24 The address 192.188.0.1 depends of your network, you should do a ifconfig for knowing yours. The result of this command will be something like this:

Access to AWS Postgres instance in private subnet

I have been working with AWS in the last days and encounter some issues when using RDS.  Generally when you're working in development environment you have setup your database as Publicly accessible and this isn't an issue. But when you're working in Production. So we place the Amazon RDS database into a private subnet. What we need to do for connecting to the database using PgAdmin or other tool? We're going to use one of the most common methods for doing this. You will need to launch an Amazon EC2 instance in the public subnet and then use it as jumping box. So after you have your EC2, you will need to run the following command. See explantion below After this, you will need to configure your PgAdmin. The host name will be your localhost, the port is the same you define in the above command. Maintenance database will be your DB name and the username you have for connecting. Hope this helps you connect to your databases.
