With GrailsCrowd a new community service has seen the world that revolves around the Grails web framework. Here you can log on Grails developers to present their projects and associates are looking for.
As it should (key word: "eat your own dogfoot") he is a Grails application. The colors are pink and light blue is not really my case, but typical web 2.0.

I'm curious if the account at the service impact on grum , my own little Grails project has.

The one with the open source Nagios monitoring well its servers and network components, is well known. The community is very large at around Nagios. But what they do is in the Japanese experiment on himself quite unique. But see for yourself:

The term REST buzzing for quite some time through the Internet. But what exactly REST is and how to implement REST using Java?
This question has been in the JAX session "Java API for RESTful Web Services" Stefan Tilkov believed Innoq and explained to me very naturally. Below I would like to briefly summarize the most important thing for me this session and hope that the entire slides vn Stefan Tilkov can be downloaded from the JAX website soon.

But back to REST.

If you look around the internet a bit to REST, REST, there are many comparisons with other techniques, such as REST vs. SOA, REST vs.. SOAP and REST vs. WS-* (short for the rather wide range of standards in the web environment).
According to Stefan Tilkov REST is comparable to the best of web services, but rather about his experiences, a different approach to high-level SOA to achieve goals.

Originally, the term REST (Re presentational S tate T ransfer) from a dissertation by Roy Fielding (see wikipedia ) is used in today's parlance, but rather in the sense of the whole "RESTful" use the Hypertext Transfer Protocol (HTTP).

After Tilkovs statements, REST can be reduced to five basic points:

  1. all things have an ID, technically implemented through the Internet in unique URI
  2. Things are interconnected
  3. The use of standard methods (uniform interface), the technical methods of HTTP
    GET - for obtaining optional cached information
    PUT - create or modify a known ID
    POST - Create or attach a sub-resource (sub-resource)
    DELETE - (logical) deletion
    HEAD - Display header information (eg size of a file before you load it down)
    OPTIONS - Return of methods that are available on a resource.
  4. Allow the different representation (also called content negotiation), such as XML or JSON string
  5. the stateless communication as it is in the HTTP protocol specifies.

What are the advantages of REST?

  • universal support in any language (eg Java, C, Perl, PHP, Ruby, C #,. NET ...) and many tools (such as wget, curl)
  • A very good scaling
  • real web integration, through the full utilization of HTTP status codes, including its
  • XML support, but also other formats such as JSON (JavaScript Object Notation

However, as applications can be implemented with REST support with JAVA?

Answer: by the Java Specification Request (JSR) number 311, which is to specify a Java API for RESTful Web Services. Stefan Tilkov takes an active part in this Spezikation, the reference implementation JERSEY exists currently in version 0.7.
Is a web framework that implements the Java environment REST very well GRAILS .

That it is worthwhile to deal with RESTful shown by the fact that Google is in the process many of its SOAP interfaces (eg for searches ) REST-based implementation.

If you're traveling, you would not like to do without the internet. Free and commercial hotspots then pave the way to a network. If you want to check before you travel, how best to even come free on the net, it was pretty easy to drahtlosunterwegs.de .

How many actual pages, is also a simple layout drahtlosunterwegs.de. A single search box, you can search for hotspots by city, street or zip code. The results are displayed in red (extra charge) and green (for free) markers on Google Maps Maps that are built into the side.

Are services for IP addresses, there are many localization. But so simple and so good prepared (with a Google Map) I have so far only utrace seen. IP address or host name and off you go.

Utrace Home

First seen at aptgetupdate
