Hallo,
weiss jemand ein (Kommandozeilen) Programm zur Rechtschreibpruefung von
XML Dateien?
aspell ist fast was ich brauche, aber leider nicht ganz. aspell -c -H kann
HTML/SGML (und XML) Dokumente pruefen. Nun moechte ich einige Tags (Code,
Kommandos usw) von der Rechtschreibpruefung ausnehmen, aber die
add-sgml-skip Option kann nicht mit XML namespaces umgehen.
Zur Not kann ich die Rechtschreibpruefung von Kate nehmen, aber wenn es
ein Kommandozeilenprogramm gibt, das nativ mit XML umgehen kann, dann waere
das meine erste Wahl.
Danke,
Thomas
Ciao lista,
da quando ho cambiato la versione di Ubuntu ho problemi
a vedere sia a vedere i video su youtube sia a sentire
gli audio in mp3 sui siti web.
Ho la versione Firefo
Ciao lista,
questa settimana su FLOSS weekly hanno parlato di excito:
http://www.excito.com
Mi sembra un buon sistema (fanless, basso consumo, DLNA server, etc.) e mi
sono stupito di non averne mai sentito parlare. Quindi volevo sapere se sono
l'unico :)
Qualcuno di voi ha esperienza con il device / con la distro?
Ciao,
Daniele
P.S. FLOSS weekly è un podcast settimanale che fa la recensione di una
soluzione FLOSS alla settimana (spesso con interviste agli sviluppatori
principali). La pagina dello show è qui: http://twit.tv/floss

Ciao Lista!
Da qualche tempo girava la voce che sarebbe stato possibile per enti ed associazioni diventare affiliati dell'OSI. Da oggi (per quello che so, ma potrebbe essere da qualche giorno fa) si conoscono i dettagli:
http://opensource.org/affiliates/about
Mi domandavo cosa ne pensano i membri di questa lista. Io credo sarebbe bello per il LUG essere in quella lista insieme a wikimedia foundation, debian e molti altri sostenitori attivi del software libero!
Ciao!

Ciao Lista.
Scusate se scrivo in inglese su un argumento molte specializato per
programmatori:
In the last few years there is a new paradigm rising in application
architecture. It is called CQRS, Command Query Responsibility Segregation.
I had the opportunity to implement a first System with this paradigm and
I would like to share my impressions:
In opposition to CRUD (Create Read Update Delete) Systems architectures
it has the following advantages:
Reduction of Complexity: A CQRS System has a clearly separated Read and
Write side thus programs are easer to write both in teams and alone.
High Testability: A CQRS System allows for easy configuration of any
state your application should be for a test.
Unlike other Architectures there is inherently no dependency on the
database to come into a state you need to test.
Real-time Collaboration: Users can manipulate shared Domainlogic and are
instantly aware of the changes. Response to Changes is percieved as fast.
Easily Distributable: Messaging oriented middle-ware is an easy
extension to the base concept of event drivenness.
No Object-Relational Mapping: Whatever OO-language you use: there is the
Problem of Object-relational impedance mismatch (
http://en.wikipedia.org/wiki/Object-relational_impedance_mismatch). This
is gone since all information is persisted in an event stream.
Inherent User insight: the center of the conceptual framework is the
event which represents the fullfilment of a user Intent. It is easy to
know what your user wanted to do with the system. This is not only UX
insight but business performance indicators.
# Has anyone allready an opinion about the topic
# Do you find CQRS interesting? Can we deepen the argument?
Danke fuer das Feedback!
Roland
