New Showcase – Javascript and Flex

Showcase by Danguer, Javascript and Flex IntegrationI’ve uploaded a new example in my showcase, this works using Flex technologies that makes the interface more easy to use but only with javascript are impossible to do.

I’ve used a download example, with normal javascript you cannot check the progress of a downloading into your computer. Of course, as this example could be not seen as of great use (but of course can simplify a lot the usability when your download links are not very clear, or in case of video, etc), this can be extended easily to upload and this is a feature very need on several sites.

Flickr for example uses a Flash uploader tool (along other sites) on a similar way, so you can upload a bunch of images/files and see the progress, making this using pure javascript only can be achieved patching the PHP sources with File Upload monitors, which is not easy and also not allowed on shared hosting, this example it can be used without problems with any normal PHP Server.

Web Dragons: Inside the Myths of Search Engine Technology

This book is an excellent introduction not only about Search Engines and how works, but all which is around it, mainly internet from the view point of find information.

The book also handle information about copyright, future and past of internet development.

Even the authors recommend to start reading on the half, surely you should start from begining ;) , since all the information is clearly explained and easy to read.

If you want to read this book searching for SEO techniques (like I though when I read the title) you won’t find anything here, well it talks about what is considered SPAM and several SEO ‘companies’ still doing like cloaking or hidden text. But the book handles very well every concept, even the Information Retrieval which sometimes can look obscure and only for rocket scientists, here this topic is clearly explained (of course the concepts) to learn how the Search Engines works.

Professional Javascript for Web Developers

This book is a great introduction for Javascript and also for those who know basics of javascript. The book is clearly explained and feature a lot of examples, but unfortunately after the DOM chapter it doesn’t show the output of scripts, but as those are specific on browser and is easy to figure the output.

The books is separated in two parts, one which talks about ECMASCRIPT and features are available on majority of browsers (and their differences).

The second part features advanced features of browsers like drag & drop, XML, Web Services and so on. Unfortunately on this parts are very specific on browser, but the book also works through it to make common objects in javascript.

The main lack is of course AJAX (even it’s discussed not as AJAX briefly in chapter 17), but is comprehensible since the book is from 2005 and the term AJAX was coined on 2005. He propose a method to achieve a bit similar of ajax with hidden frames; by the way this kind of method should be avoided in programming, I said this because I’ve found recently written articles which propose the same; this technique was fine when there was no AJAX developing but now only look as a rusty method to simulate AJAX (and is harder to control).

The author now have written recently a book of AJAX (Professional Ajax, 2nd Edition (Programmer to Programmer)), which surely is worth of read.

In conclusion, this book is excellent to learn and deploy your Javascript skills, but I think the book should be readed deeply until the DOM chapters, later chapters should only take as basic information, since are parts have changed a lot since AJAX.

Communicating Design: Developing Web Site Documentation for Design and Planning

Communicating Design - BookI recently finished reading this excellent book.

Even the first part not clearly explained like other books, the personas chapter is very good to present this good resource. It worth to keep in mind this phrase: “I think our users want this“, which is a common idea in developing / designing I’ve found between several people I know.

The second part keeps you engaged and the third part is very good since as the concepts are already explained the author can connect it through commonly used deliverables: Site Maps, Flow charts, Wireframes, Screen Designs.

The author try to advise some of the deliverables could be outdated in a short term due the fast developing in dynamic web sites, but I think rather to been outdated they will be adapted in newer models. The Software engineering field still using several techniques and ideas from the start of this field some decades ago and only have polish many of their techniques and models (of course also have developed new techniques and models like UML).

Without doubt a book to read and ground several concepts that are of daily use in usability working.



Curso de Tecnologías Web

A partir del lunes 16 de octubre y durante cinco semanas (aproximadamente) estaré dando un curso sobre Tecnologías Web. La idea es que el participante aprenda de todo un poco y tenga ejemplos claros (y sencillos) de código que se utiliza todos los días en la mayoría de proyectos.

El temario se puede consultar aqui:

Se verán temas como videoconferencia y streaming de video (usando Adobe Flex), por supuesto también AJAX, Javascrip, MySQL y PHP =).

El progreso del curso en notas se puede ver aqui (aunque la mayoría serán puestas en la red hasta cuando el curso comience):
