On Line Prize Draw
A friend / partner needed an online Prize Draw application to select a random participant to give a gift during the live event on youtube. He asked for help, and wanted that participants provided some information to participate, and did not want free tools with ads.
So I wrote this simple Online Prize Draw web app using HTML, PHP, JavaScript and MySQL.
The source code is here:
https://github.com/rafaelaroca/OnlinePrizeDraw
Usage:
1. Participants must access a link and provide their details, such as name, phone and email
2. The host accesses a page that runs the prize draw
3. All participants area available on the database and the list can be exported to Excel

BIPES Maps – Geographical Information System integrated with BIPES
Some BIPES (www.bipes.net.br) users requested a map feature, allowing sensors to be seen on a map, with real time updates or even moving objects / vehicles on the map controlled from BIPES HTTP Web Requests.
In that way, we have built a simple, yet functional Geographic Information system for BIPES.
Source code is here:
https://github.com/rafaelaroca/bipes_maps/
How to use:
https://bipes.net.br/map/doc.html
Usage example:
1. Define a session ID, and make sure this session is clear for you.
https://bipes.net.br/map/clearSession.php?session=1763
2. Open the map with your session ID
https://bipes.net.br/map/main.php?session=1763
3. Manage the map as you prefer using this interactive interface to create / edit / delete / update markers:
https://bipes.net.br/map/crud/index.php/main/static
https://bipes.net.br/map/crud/index.php/main/dynamic
4. Use our webservices so that your application can update the map:
https://bipes.net.br/map/doc.html
For example, if you want to add a marker to the map:
Icon used:
https://image.flaticon.com/icons/png/512/2540/2540201.png
Add the same icon in another position
Add the same icon in another position, again!
The markers will automatically show on the map!
Now you can also move these markers with updatePosition or change data! Use BIPES HTTP GET Block to interact / control the map!
Happy BIPEing 😉

BIPES meets SAP
SAP company provides Enterprise Resource Planning and other corporate software widely used all over the world in companies of all sizes and types. Today, I found an article on SAP Blogs from Gunter Albrecht describing / showing how he quickly developed an IoT application using BIPES and integrated it with SAP Business Technology Platform (SAP BTP).
He used an ESP32 board, a temperature/moisture sensor and created a block based program on BIPES to send these sensor readings to SAP BTP using secure MQTT connection!
Thank you Gunter for trying BIPES and integrating it with SAP BTP, even for a quick test. We were happy and proud!

Feynman
“You cannot get educated by this self-propagating system in which people study to pass exams, and teach others to pass exams, but nobody knows anything. You learn something by doing it yourself, by asking questions, by thinking, and by experimenting.”
