Usar Gmail para cuentas de correo que no son de Google.

Este procedimiento sirve para cuando tenemos una cuenta de Gmail y queremos usar Gmail como servicio para gestionar otras cuentas que no son de Google, sin tener que decir a nuestros contactos que hemos cambiado de correo. Es decir para nuestros contactos no cambia nada: siguen usando nuestra dirección de correo que conocen. Para nosotros cambia que usamos el servicio de Gmail para gestionar este correo y, aunque sigue activo, ya no necesitamos usar el servicio del proveedor original.

Repitiendo este procedimiento se pueden integrar varias cuentas externas en una ÚNICA cuenta gratuita de Gmail. También se puede repetir usando varias cuentas independientes de Gmail gratuito. Si se desea un servicio unificado para la gestión de diversas cuentas de una organización con Gmail, deberá contratarse el servicio de pago "Google Apps".

How to create PDF files from XML using Apache-FOP

XML

Nowadays, XML is the native format of many applications, Oracle APEX for example, partly bases its reporting systen on XML. Middleware as Oracle BPEL, SAP PI, IBM Websphere and of course many Web services are also XML based. XML is also being used as exchange format in business to business transactions, for example for e-Invoicing. In these and many other environments there is often the need to create PDF files from XML.

XSL-FO

In the past PDF files would be created using proprietary reporting tools that would use a database as data source. Additionally these tools are programming language specific. Later on the XSL-FO standard allowed for a better way to do it in many cases.

What is new about XSL-FO?
- it is programming language neutral.
- it is a standard so you are not tied to a vendor.
- it uses XML as data source.

Apache FOP

One implementation of the XSL-FO standard is Apache FOP. One important aspect about this implementation is that the Apache license model allows to use it in commercial environment.

Many free/open source products have a license model that puts strong restrictions on the way you may use the software. Not surprisingly there are software companies that do not allow the use in their code any open source software other than Apache Foundation one. So if you use Apache you know you are on the safe side.

J4L Barcodes 1D for Ruby

I was intrigued about all the buzz around the Rails framework and the Ruby language, so I thought it was the time to check it out by myself and start by learning Ruby. So, as I usually do, I assigned myself some specific learning task: in this case porting the J4L barcoding software from PHP (which in turn was ported from Java).

Money transfer adventure

During 2010 I worked mostly on this project. J.M.E., the web designer, and I worked with Iker Marcaide to develop the first version of the international money transfer web application, which was launched around June, just in time to win the "HiT Barcelona global technological innovation summit". 

As clients started requesting transfers we refined the user interface until October, moment at which the result was compelling enough for investors to pour into the project its first million dollar funding.

Until this point the service was a generic person-to-person money transfer service. With the new investment and subsequent hiring of the first group of employees, the business focus specialized on tuition payments, and a new application was started with a very different workflow.

This initial web application was developed using the Zend Framework.

It was very exciting to participate in this project and contribute to its early success!
