Con oltre 700 bug fixati dalla Beta 2, con questa versione il team di sviluppo chiede di fare un ultimo sforzo e testare in maniera massiccia tutto il sistema, inviando feedback, consigli e quant'altro prima della Release Candidate prevista per il 29 Maggio. Tra le novità più importanti troviamo l'inclusione dell'ultima versione di KDE 4 e l'installer disponibile nel CD live, stile Ubuntu, feature che aspettavo da tempo...

Per l'annuncio, qui!

It is interesting how simple specialised devices cope with their functions much better than a all-in-one PC. Sometimes, I wish to fall asleep with some music on. But how annoying it becomes, when you have to get up in the middle of the night to turn off your PC, which has been playing something all this time. Digital radios have mastered the trick decades ago. Of course there is a way to make a PC do it.

Running linux, I thought that it should be fairly straightforward to shut it down after say half an hour automatically.

Something like shutdown (below) will kill the X. The KDE then will just exit without saving the session. Next time you log on, you will see some session from a distant past. If you do this often, it gets really annoying. Also this requires superuser privileges on some distributions.

[sourcecode language='ruby']
/sbin/shutdown -h now "Power button pressed"
# or
halt
[/sourcecode]

Then how to make KDE quit without calling any dialogs (I am sound asleep by this time and I can't afford to wake up and press 'OK')? There is a way.

[sourcecode language='ruby']
dcop ksmserver ksmserver logout 0 2 2
[/sourcecode]

The three numbers are explained below (see source):

First parameter: confirm
Obey the user's confirmation setting: -1
Don't confirm, shutdown without asking: 0
Always confirm, ask even if the user turned it off: 1
Second parameter: type
Select previous action or the default if it's the first time: -1
Only log out: 0
Log out and reboot the machine: 1
Log out and halt the machine: 2
Third parameter: mode
Select previous mode or the default if it's the first time: -1
Schedule a shutdown (halt or reboot) for the time all active sessions have
exited: 0
Shut down, if no sessions are active. Otherwise do nothing: 1
Force shutdown. Kill any possibly active sessions: 2
Pop up a dialog asking the user what to do if sessions are still active: 3

Ho cambiato idea.

Mi sono infatti ricordato di aver scritto un libro in formato pdf in cui, tra l'altro, si spiega dettagliatamente la configurazione sia di KDE che di Konqueror che uso abitualmente.
Mi sembra ovvio rimandare pertanto gli interessati alla lettura del volumetto (che trovate qui: Linux: come e perché (versione pdf)).

Vi auguro quindi buona lettura.

Cos'è Prism? Beh diciamo che è un browser firefox castrato che permette di navigare in una web-application (google calendar, gmail...wordpress) come se fosse installata nel nostro pc. Ovviamente dobbiamo essere connessi a Internet però! Questo è molto comodo, clicko su una icona e compare la mia web-application senza fronzoli, segnalibri, barre ecc ecc.

Installazione

Beh mi riferisco alle debian derivate come al solito (# = permessi di root)

# apt-get install prism

Uso

Ok ora lo abbiamo, per utenti KDE, nel menù K alla voce Internet. Ad ogni avvio ci chiede quale URL della web-application, che nome darle e il resto delle opzioni diamo tutto flaggato. Ora sul nostro Desktop appare la nostra icona da usare a go go.

Migliorie

Ora mmm che brutto avere un'icona così sul desktop, io voglio tutto ordinato come se fosse una vera e propria applicazione. Ok niente di più facile, tasto destro sopra l'icona della web-application sul desktop, Proprietà,  Applicazione e ci copiamo la stringa di Comando. Ora andiamo ad editare il menu K.

Tasto destro sopra il menù K, Sblocca pannello, Editor Menù ed andiamo ad aggiungere su Internet una nuova voce, basta impostare sul parametro Comando indovinate un po'? Quello che ci siamo copiati dall'altra parte? Che bravi! Da qui cambiamo anche icona clickando sull'icona e scegliendone una di nostro gradimento. Salviamo tutto, cancelliamo pure l'icona dal desktop.

Ora se vogliamo possiamo aggiungere la nostra applicazione sulla applet Esecuzione Rapida  visto che è una applicazione presente nel Menù K, tasto sulla maniglia, Menù di configurazione rapida, Aggiungi applicazione e po vi arrangiate ;-) Dai sto spiegando come ad un utente di Windows!

Sì ma il dizionario Italiano?

Già, io ho provato ad aggiungere quello di Firefox ma non ha funzionato (alla fine prism è un firefox castrato) ma niente da fare. Ho trovato questa guida per Windows e l'ho adattata per Linux.

Prendiamo il file .zip che c'è a quel link, lo unzippiamo nella nostra home e poi diamo

# mv it-IT.aff /usr/lib/xulrunner-1.9b5/dictionaries
# mv it-IT.diff /usr/lib/xulrunner-1.9b5/dictionarie


Ok ora creiamo una web-application provvisoria con URL about:config. Avviate l'applicazione, vi chiederà di andare avanti perché potreste fare danno. Ok ora possiamo cambiare tutto quello che ci serve, ecco come impostare cosa e come.

general.useragent.locale - it-IT
intl.accept_languages - it-it, it, en-us, en
spellchecker.dictionary - it-IT

Bene, ora usciamo, cancelliamo l'applicazione temporanea che abbiamo usato per fare questo ed ora godetevi il dizionario Italiano.

PS non ho provato a trasformare prism in Italiano, i comandi intendo, ma ok...chi se ne frega.

Next screenshot is showing Dolphin (default File manager, replaces Konqueror), Kate (KDE advanced text editor) and Okular (document viewer for KDE4).

Here we can see System monitor (showing CPU Load, Physical memory, Load average and Swap memory), Gwenview (Image viewer), The Konqueror (they call it Swiss-knife) and SpeedCrunch (Simple calculator application).

In next screenshot, KmPlot (A mathematical function plotter), KGoldrunner (An arcade game) and Dragon player (Default video player for KDE4).

KDE4 is something, make you forget VISTA and even OSX.
and this is just the beginning.
KDE4 version you are looking at is KDE 4.0.3
In july KDE 4.1 is coming, based on Qt 4.4,
yes, you are right !!!
The goodness of webkit and phonon integration...
I just can't wait...
By the way,
I'm using Kubuntu-KDE4 as my default OS.
don't remember when I logged in Vista last time. :P

so Download the Live disk, try it...
and If it suits (condition is always TRUE), install it...
and one more thing, If you are afraid of partitions there is WUBI to take you out of trouble..
now you can install Linux distributions (atleast buntus') as normal softwares in windows..
yes, no need to have extra partitions....

After lots of waiting Red Hat Released their latest Desktop/Server version of Fedora Linux ;) Lets take a quick look at its feature :) Fedora is a Linux-based operating system that showcases the latest in free and open source software. Fedora is always free for anyone to use, modify, and distribute. It is built by people across the globe who work together as a community: the Fedora Project. The Fedora Project is open and anyone is welcome to join.

• This release features GNOME 2.22. GNOME now includes a webcam photo and video creation utility called Cheese, improved network filesystem support, a new international clock applet, Google Calendar support and custom email labels in Evolution, a new Remote Desktop Viewer, improved accessibility features, and PolicyKit integration.
• KDE 4.0.3 is available in the KDE Live image as well as the regular DVD.
• Xfce 4.4.2 is available as part of this release.
• NetworkManager 0.7 provides improved mobile broadband support, including GSM and CDMA devices, and now supports multiple devices and ad-hoc networking for sharing connections. It is now enabled by default on installations from DVD, CD, the network, and Live images.
• The Fedora installer, Anaconda, now supports partition resizing for ext2/3, NTFS filesystems, creating and installing to encrypted file systems, improved Rescue Mode with FirstAidKit, independent locations for the second stage installer and the software packages. A redesigned, larger netboot.iso image now features a second stage installer partly for this reason.
• Live USB images now support persistence, so your data and setting changes will be preserved even after rebooting.

• PackageKit, a new set of graphical and console tools, with a framework for cross-distribution software management, has replaced Pirut in this release of Fedora. The PackageKit graphical updater is available instead of Pup. Behind PackageKit, the performance of yum has been significantly improved.
• FreeIPA makes managing auditing, identity and policy processes easier by providing web-based and command line provisioning, and administration tools to ease system administration. FreeIPA combines the power of the Fedora Directory Server with FreeRADIUS, MIT Kerberos, NTP and DNS to provide an easy, out of the box solution.
• Ext4, the next version of the mature and stable ext3 filesystem is available as a option in this release. Ext4 features better performance, higher storage capacity and several other new features.
• This release of Fedora uses Upstart, an event-based replacement for the /sbin/init daemon.
• Firefox 3 brings a number of major improvements including a native look and feel, desktop integration, the new Places replacement for bookmarks, and a re-worked address bar.
• The completely free and open source Java environment OpenJDK 6 is installed by default. IcedTea 7, derived from OpenJDK 1.7, is no longer the default. IcedTea includes a browser plug-in based on GCJ, and is available for both x86 and x86_64 architectures. GCJ is still the default on PPC architecture.
• OpenOffice.org 2.4, with many new features, is available as part of Fedora 9.
• Fedora now includes Perl 5.10.0, which features a smaller memory footprint and other improvements.
• Fedora now includes TeXLive to replace the older, unmaintained TeX distribution.
• Fedora 9 features a 2.6.25 based kernel.
• Kernel crashes can be more automatically reported to Kernel oops bugcount and diagnosed in a friendly way via the kerneloops package installed by default. Crash signatures are commonly referred to as oopses in Linux.
• Work on the start-up and shutdown in X has yielded noticeable improvements.

The session management support is pretty similar to the one that Opera has. Let's say it's inspired in Opera =). And as everyone likes screenshots, here there is one that shows the new menus for session management:

So you can easily save current session, open one of the saved sessions, or manage current sessions. And only one more item was added to the File Menu, which is the same menu where session management resides in Opera.

The Manage sessions dialog lets you save current session in a new session or in an existing session (overwriting it). It also can rename an existing session, or delete it. Or even open one of those sessions. Quite straightforward if you look at it, actually:

And I have reserved the best part for the end. Proper crash session recovery! Because Konqueror shouldn't, but it can crash sometimes. And it crashes even more when you use KDE trunk. Until now, the only option you had to recover from a crash was using the crash plugin which is sub-optimal.

What I've done is something similar to what Opera, Firefox and many others browsers do: Save session every X seconds (it's configurable via konquerorrc, 10 seconds by default as in firefox). This is done for all konqueror processes, and it's saved in ~/.kde/share/apps/konqueror/autosaved/. Each process saves its session timely there in a file with a name similar to ":1.114" which identifies it. When a konqueror instance is closed cleanly, its file is removed.

Thus, every time a new window or konqueror process is launched, Konqueror reads that directory and asks to DBus if there's any service registered with the name ":1.114", for example, or whatever name have the autosaved files. This is done very fast, because no text parsing or waiting is needed, so the user doesn't feel any delay.

If for some reason there's a file with a name that is not related to a registered dbus service, that means that something wrong happened i.e. a konqueror process crashed or froze. And in that case, you get this nice dialog:

Which allows you to restore session if you want, or not, or even not restoring it now but restoring it later (opening a new konqueror process / window). As David Faure suggested me, it also allows you to check "do not ask again" and always do whatever you choose automatically without asking everytime. Nice isn't it?

There' still some related fixes I want to add to SVN before hard feature freeze, like adding a KAction menu to "Hibernate konqueror", i.e. Save current session and close konqueror, so that next time you open konqueror it can be restored. Also listing the crashed and still not restored sessions (i.e. you clicked in "ask me later") in the sessions menu.

Oh and adding an option to undo closed tab to right click menu of the konqueror tabbar is a must too, I use that option a lot now in firefox and we need it too ;-).

Per prima cosa mi sono procurato Sound Converter che a differenza di ffmpeg non perde la qualità del file e è più facile di utilizzo. Infatti, tramite la sua interfaccia grafica, è possibile selezionare i vari file e non solo! Se si sbircia un pochino tra le impostazioni potremo vedere benissimo alcune chicche davvero utili! Le vedremo insieme successivamente... per ora limitiamoci a installare il programma e a convertire un file di prova. Apriamo il nostro amato terminale e digitiamo:

sudo apt-get install soundconverter

Finita la procedura di installazione posiamo trovare il nostro programma nel menù, ma se vogliamo vedere un po da vicino possiamo benissimo avviarlo da terminale con il solito comando:

soundconverter

Una volta eseguito il programma compare una bella finestra facile e intuitiva: 3 tasti 3 menu e la lista di files da convertire che per ora è vuota. Quando vogliamo aggiungere un file alla lista dei files da convertire clicchiamo su "Add File" e si aprirà la solita finestra di selezione file. Se invece vogliamo convertire i file che sono contenuti in una cartella (anche i file delle sotto cartelle) possiamo cliccare su "Add Folder" e come prima, si aprirà la finestra di selezione della cartella. In fine i nostri file verranno caricati dal programma e analizzati i dati interni! (artista, autore, album, numero traccia ecc...). Quando avremo finito di aggiungere file alla lista potremo cliccare su "Converti" o "Convert" e il programma trasformerà i file da un formato ad un altro. Terminata la procedura automatica avremo i nostri file pronti per l'esecuzione! Vediamo ora le chicche applicabili tramite le impostazioni! Andiamo nel menù a tendina della finestra, in alto a sinistra. Selezioniamo "Modifica > Preferenze". A questo punto si aprirà un'altra finestra di preferenze che ci aiuterà nella trasformazione. Per prima cosa ci viene chiesto dove andranno a finire i file trasformati. Io ho selezionato che i miei file vadano tutti nella cartella con tutti i file musicali e che vengano create le cartelle ./artist/album per avere un ordine preciso ed accurato ma voi potete benissimo scegliere una vostra cartella o un vostro lettore portatile! Poi ci chiede il nome da attribuire ai file convertiti. io ho selezionato "Artis - title" così anche su lettori portatili sarà possibile leggere chiaramente il titolo e l'artista. Per ultima cosa ci viene chiesto il tipo di file finale, ossia il formato di file che si vuole ottenere: abbiamo una vasta scelta tra Ogg Vorbis, MP3, FLAC e WAV. Io ho scelto Ogg Vorbis in quanto è un formato opensource e che ha le stesse caratteristiche degli Mp3 solo che non devo pagare la licenza. Riguardo alla qualità del file non possiamo avere dubbi: High o Very High è la scelta migliore, anche se potete scegliere voi a vostro rischio e pericolo ;-)

Bug Days are hosted by the KDE Bugsquad approximately once every two weeks. Their purpose is to check back through the large numbers of bugs stored in the KDE Bug Tracking System and investigate how to reproduce them. This means that when developers come to the bug reports to fix them, all the information they need is available on the report and they don't have to spend huge amounts of their time investigating the bugs - they can just focus on fixing them. During each Bug Day, we will focus on one area of KDE in particular. For this Bug Day, we will be focusing on general bugs in Konqueror. More information can be found on the Bug Day 4 Techbase Page.

Helping sort through these bugs now will help greatly in having a polished KDE/konqueror for the Intrepid Ibex. In addition to the KDE triaging procedures, it will help to look through the Konqueror bugs on launchpad and cross link them with the KDE bug you are working on. This is especially helpful if you can find crash reports from apport since they provide all the debugging information the upstream developers will need to fix a crash.

طبعا كل محبي لينكس كانوا مثلي في حالة ترقب لنزول النسخة التاسعة الرسمية من فيدورا .. المسماة سولفر.

و كما هو معروف و لا يحتاج لكثير من التذكير ان فيدورا هي النسخة المحبوبة و المجانية من توزيعة لينكس الاسطورية ريدهات

طبعا ايام زمان كنت استخدم ريدهات 7 و كانت اول اصدارة من لينكس اقوم بتنصيبها و لكن بعد هذه الاصدارة ابتعدت عن ريدهات لاسباب او لاخرى و لم اجرب ريدهات منذ ذلك الوقت حتى نزلت الاصدارة التاسعة من فيدورا و ها انا اعود لزمن الـ RPM بعد زمن طويل ...

التنزيل و التنصيب :

من اول ساعات نزول فيدورا 9 قمت بتنزيل نسخة الكي دي اي 4 لارى المميزات القوية التي وعدنا بها ، من هذا الرابط :

http://fedoraproject.org/en/get-fedora

طبعا رابط الدايركت لم يكن يعمل الا ببطء شديد من كثرة الطلبات فحملت الاصدارة عن طريق التورنت . نسخة اللايف سي دي .

كل شيء جميل اقلاع سلس و عملية تنصيب بواجهة رسومية سهلة حتى لاصغر المبتدئين ..

الدرجة 5-5

سرعة النظام و التعرف على الاجهزة :

لا ادري من قال ان الكي دي اي بطيئة ! سرعة عجيبة و لا ادري هل السر في انها النسخة الجديدة من كي دي اي ! لا اعتقد ذلك فهي ايضا سريعة جدا في اصداراتها السابقة الموجودة على سلاكس و سلاكوير !..

سرعة استجابة بالرغم من انها كانت تعمل على الايف سي دي ، و سرعة في التحكم بالمهمات المتعددة ..

اما التعرف على العتاد فقد  كان مبهرا تعرف على كل شيء اوت اوف ذا باكس @ الصوت 100% ، كرت الشاشة بالدقة المطلوبة ، الوايرلس بكفاءة عالية , التوشباد و و و الخ لم احتج اصلا للدخول الى لوحة تحكم او استخدام سطر الاوامر ..

الدرجة 4-5

الواجهة الرسومية و الثبات :-

اما الواجهة الرسومية فهي ابداع فني و جميل جدا .. اعجبني فيها اشياء كثيرة ... الخلفية و الثيم ساحرة .. خاصية اضافة الويجدتس ممتازة و سهلة و تعطي طابع احترافي لسطح المكتب اعجبني منها القاموس و الساعة و السلايد شو للصور كما هو في الفيستا و ايضا تحفة فنية جميلة اول مرة تمر علي هي القدرة على اضافة ويجدت خاص بعرض كاريكتيرات على سطح المكتب -- مسلية جدا!

و اما الخاصية الجميلة و الرائعة هي الاخرى ! خاصية الكومبيستر للكي دي اي و قد هالني مستواها الرائع فقد تفوق على غريمه في اكس اف سي اي بعشرات المرات و لن ابالغ بمقارنته ببيرل و ميتسي و لكن شيء خيالي حقا جرب بنفسك !..

و اما الثبات فكان مدهشا و يتفوق على كثير من التوزيعات الاخرى ..

الدرجة 5-5

البرامج :-

مكتبة البرامج مهولة و مصنفة تصنيفا جيدا و طريقة تركيبها لا تختلف كثيرا عن النت باكج في الزينوالك او السنتباك منجر في الاوبنتو .. طبعا برامج فيدورا معروفة انها rpm على كل حال اغلب البرامج موجود لها صيغة ار بي ام و لكن ما لم يعجبني في اصدارة كي دي اي انه على الرغم من تواجد الكثير من البرامج الافتراضية و لكنها ليست الخيار المثالي مثلا :

بدل الفايرفوكس لديك كونكويرر ، لا يوجد اوبن اوفيس افتراضيا ، لا يوجد اماروك , .. الخ الخلاصة لم اجد برامجي التي تعودت عليها في اكس اف سي اي و جينوم فكان لزاما علي ان اقوم بعملية طويلة في تنصيب برامجي الافتراضية بدل البرامج الموجودة.

الدرجة 4-5

الخلاصة :

لم يسعني الوقت لتجربة الاصدارة اكثر و اكثر و التعمق في مزاياه مثل الاس اي لينكس و لكن لا بأس اخي الكريم لو تتطلع بشكل مختصر على هذا الرابط لمزيد من المعلومات عن مميزات فيدورا :

http://fedoraproject.org/wiki/Overview

دعم العربية ممتاز و مرونة عالية في تخصيص سطح المكتب و المؤثرات و تنصيب البرامج .. لا ارى انها اصعب من اوبنتو  بكثير !!

اصدارة رائعة استحقت الدرجة النهائية :

4.5 من 5

kdesupport: Failed after 9 seconds.
kdelibs: Failed after 5 seconds.
kdepimlibs: Failed after 2 seconds.
kdebase: Failed after 41 minutes, and 38 seconds.
l10n-kde4/it: Failed after 25 seconds.

In poche parole non sono riuscito (dopo ben 3 lunghi tentativi) a compilare KDE4... il motivo: "cmake non funzionava bene" ... e pure la mia bella macchinuccia era dotata di cmake! A parte questo, vorrei sapere come procede la compilazione da parte di Olympicmew... mistero o ci ha rinunciato? :(
Avrei da sottolineare una cosa: Gnome 2.22 mi ha deluso come KDE4 al primo lancio ufficiale... possibile che debba passare così tanto tempo?

PS: Amo e utilizzo Gnome!

A Red Hat acaba de liberar o novo Sistema Operacional Fedora 9, ontem terça-feira, dia 13 de Maio de 2008, seis meses após o lançamento do Fedora 8 em Novembro de 2007.

O sistema fará a alegria dos usuários, pois o uso em drives portáteis USB ficou muito mais fácil, a sua principal inovação. Com essa nova funcionalidade, imagens do Fedora 9 podem ser adicionadas a um pen drive, sem risco de perda de dados, reparticionamento e reformatação.

Abaixo seguem algumas das principais mudanças no sistema operacional:

- Adição da nova interface gráfica, KDE4.

- Nova ferramenta de busca de arquivos, que ficou muito mais fácil e digamos, “esperta”.

- Integração do OpenJDK6 (Java SDK Standard Edition).

- Melhorias consideráveis no Network Manager, tais como suporte mais amplo a banda larga móvel, múltiplas conexões, e edição e compartilhamento de conexões.

- O Gnome 2.22 conta com o novo World Time Clock, performance bem melhor no seu sistema de arquivos, gerenciamento de energia mais dinâmico, melhorias de integração com bluetooth e suporte direto a podcasts.

Uma boa notícia é que o download do novo sistema operacional já está disponível no site Fedora ProjectWeb.

Divirtam-se!!! Eu já estou fazendo o download da minha imagem!!! =)

E' però mia ferma intenzione continuare ad utilizzare KDE3 il più a lungo possibile anche se questo comporterà l'abbandomo di programmi come KOffice (la cui nuova versione girerà solo su Gnome-QT) in favore di programmi simili, come Open Office per la video scrittura.

Dal momento che uso normalmente Compiz, inizio dal caricamento di quest'ultimo al boot.
Come premessa è ovvio che debba essere inizialmente installato.
Per installarlo basta mettere nel file /etc/apt/sources.list la riga:

deb http://download.tuxfamily.org/shames/debian-sid/desktopfx/unstable/ ./

e con synaptic installare i vari pacchetti di Compiz.
Resta ora da farlo partire al login.

Io utilizzo il seguente script (un semplice file di testo reso eseguibile e salvato in ~/.kde/Autostart):

#!/bin/bash
sleep 10
kwin --replace&
killall kdesktop &
sleep 10
killall fusion-icon &
sleep 3
fusion-icon &
sleep 27
python -u /home/mario/.screenlets/WidescapeWeather/
WidescapeWeatherScreenlet.py&

sleep 3
wmctrl -n 2&
sleep 1
wmctrl -n 1&

La prima riga indica che è un eseguibile bash.
La seconda riga attende che KDE sia caricato (KDE si ricorda di fusion-icon e disabilita kwin)
La terza riga riabilita kwin (altrimenti poi fusion-icon mi provoca un crash)
La quarta riga mi elimina Kdesktop (che non mi serve e impedisce a Wallpaper-plugin di funzionare)
La quinta riga attende che KDE termini il caricamento dei vari programmi e applets
La sesta riga elimina fusion-icon
La settima riga aspetta per essere certi che fusion-icon sia chiuso
L'ottava riga lancia fusion-icon
La nona riga aspetta che compiz venga competamente avviato
La decima riga lancia la screenlet WidescapeWeather
L'undicesima riga aspetta che WidescapeWeather sia completamente avviato
La dodicesima riga imposta due desktops
La tredicesima riga attende che i due desktop siano avviati
La quattordicesima ed ultima riga imposta un unico desktop

Gli ultimi due comandi servono per evitare che kpager mostri un unico grande desktop al posto dei quattro corrispondenti alla faccia del cubo.
L'esecuzione dello scripi richiede circa un minuto per essere completata ed alla fine il risultato è quello dell'immagine:

Come si vede un desktop che utilizza KDE con due pannelli, uno inferiore ed uno superiore. Con l'applet del tempo posizionata al bordo superiore destro dello schermo (se fosse stata fatta partire prima di caricare Compiz, sarebbe sotto la linea occupata dal pannello superiore).
La peculiarità della mia configurazione di KDE è l'assenza di kdesktop (e quindi di qualsiasi icona sul desktop), la presenza di una barra superiore, a scomparsa, che mi mostra le finestre aperte con la loro anteprima e la configurazione della barra inferiore che mi permette di avere in vista tutto ciò che mi occorre.

Ma su questo ritornerò in un post successivo.

1. Qt requires less LoC (Lines-of-Code) than GTK+. The numbers stated range from 30% to 200%. Also, Qt based code is more readable than GTK+ based code. So, Qt is more productive.
2. Qt has much better documentation, both online as in books. Most GTK+ related educational stuff is outdated. The online reference is there, but not as powerfull as the Qt reference.
3. Both have python bindings, but the same is true for the documentation: The PyQt documentation is much better, both online as in books, as with PyGTK.
4. Qt is natively cross platform and performs well on Linux, Windows and OSX, using their native look and feel. GTK+ is cross platform, but it is said it doesn't perform on Windows very well.
5. Trolltech, the company that developed Qt is acquired by Nokia. This is very troubling. Nobody really knows what this will do to the toolkit. GTK+ is owned by nobody, which is very positive. The Free Qt edition is protected through the Free Qt Foundation, but if Nokia so desires, it will just let it fork and give the community there own version of it. Who will then maintain it? KDE devs? That only means KDE development slowing down even more.
6. All "big" linux vendors (Redhat, Novell, Ubuntu) choose Gnome as their default GUI, and it shows. There is far more polish in the product. Just try Ubuntu 8.04 and then try Kubuntu 8.04. Kubuntu has one maintainer, Ubuntu many.
7. KDE right now is in the transition from KDE3 to KDE4, a massive undertaking. As a result of that, development in KDE3 has ceased mostly, but KDE4 isn't ready yet either. It's mostly a mess.
8. KDE developers are reluctant to replace KHTML with WebKit, while I see this as very important. Browsing the web with KHTML is pretty painfull. Using WebKit will ensure browsing is on par with Safari. Web Developers don't give a damn about KHTML. They do about Safari.
9. The look and feel of non natvie apps like Firefox and openoffice is very ugly in KDE, but look very integrated in Gnome.
10. The general ugly-ness of KDE. Clearly, KDE developers don't care about aesthetics or are not able to make things look good. As a result, a default KDE install doesn't look good. It can be made to look better with modifications, but it is the first impressions that count's. And it is not a good first implession. There is a role for the distro maintainers here too.
11. People rant about the smoothness of Gnome, how well everything is integrated, how polished everything looks. The time it takes within the KDE project to get out something as simple as HTML enabled signatures in KMail is unbelieveable. If I change my font settings or mouse pointers of whatever in Gnome, it changes immediately. In KDE I have to logout/login. Why? When I plugin a iPod in Gnome, it's connected and ready to use in the sound app of Gnome. In KDE (Amarok) is needs to get configured, and then "connected". Why?
12. Word is that OpenOffice under-the-hood is a big mess. It's bloated and takes a long time to start (getting better though). My great hope is that Koffice 2.0 will be great. It has a much cleaner codebase.

I sure hope the KDE project will get on it's feet again. KDE4 looks promising, but it's current state is not good. KDE3 is on a standstill. KDE4 with Koffice2 are my big hope. If it doesn play out well, it will be the death of the KDE project. Right now Gnome is in much better shape.

I _want_ to develop using Python and Qt4. I Like the toolkit and I like the cross platform capability. I already invested in a Qt4 and a PyQt4 book. But, as this post shows, I am in doubt. Should I invest my time in learning (Py)Qt or (Py)GTK?

In my Kubuntu installs I am using Konqueror. I had said that Konqueror is slow. Not anymore, Konqueror is faster than anything I have tried. I don't know what the did but it worked. I do have issues with the KDE 4 version on Konqueror, such as not being able to play streaming audio. I have no such problems with Konqueror in KDE 3.5.9. At work I have installed Safari from Apple to give it a go, but I haven't done any thing with it yet.

I haven't been using Opera since updating my computers, but as soon as I finish this post I'll be installing it on the KDE 4 computer and hopefully It'll have streaming audio working. I'll let you know.

Una de las gracias de esta version, es que al descargar un archivo y abrirlo, nos pregunta con que programa hacerlo.

Es mejor que lo que había antes, pero aun no es tan bueno. El programa lo escogemos para el protocolo, no para "el tipo de archivo", así que todos los archivos locales (interpretados como protocolo file) se agregaran a la lista.

Además, igual es latoso asociar cada tipo a un programa distinto, cuando KDE maneja su propia asociación de archivos (y de antemano). Entonces acá fue donde Amsn me dio una pista:

El comando kfmclient exec /archivo/de/entrada lo que hace es abrir la direccion dada con el programa asociado en KDE. Si es un directorio lo abre en Konqueror o Dolphin. Si el tipo de archivo no está asociado aún, pregunta con que programa abrirlo.

Ahora el problema con Firefox, es que deja escojer "el programa" con que abrir los archivos (ya convenimos que se va a usar kfmclient) pero no deja pasarle argumentos (es necesario el "exec"), por lo tanto mi solución fue la siguiente:

• Creamos un script como root llamado /usr/bin/abrircon, para eso puede ejecutarse:

sudo nano /usr/bin/abrircon

• O sino:

• Le pegamos el siguiente contenido:

#!/bin/bash
kfmclient exec $1

• Finalmente, le damos permiso de ejecución (también como root)

sudo chmod +x /usr/bin/abrircon

Ahora, en Firefox, la proxima vez que queramos abrir un archivo recien bajado, preguntará con que programa abrirlo. Entonces le damos la dirección de nuestro script:

/usr/bin/abrircon

Ojo: Antes de ponerle que "no vuelva a preguntar más", prueben su funciona. Para el próximo archivo, tal vez quieran que no pregunte más.

Si por esas cosas de la vida, ya habian puesto que no preguntara más, lo que se debe hacer es (con Firefox cerrado), es editar un archivo dentro del perfil de firefox, que se ubica en la siguiente carpeta:

~/.mozilla/firefox/<carpeta del perfil>

donde <carpeta del perfil> es un nombre generado aleatoriamente la primera vez que ejecutan Firefox.

El archivo en cuestión se llama mimeTypes.rdf

Se debe buscar la linea que dice

<RDF:Description RDF:about="urn:handler:local:

(La deje incompleta a propósito). Si bajo esa linea hay algo como:

NC:alwaysAsk="false"

Solo se debe cambiar el false por true.

PD: Toda esta tontera no abría sido necesaria si desde el principio el Firefox permitiera pasarle argumentos a los programas escogidos, además de que en ningún panel/menú/opción encontre como desactivar "que no preguntara más" al "abrir un archivo con...".

There are a number of new exciting features to be found in Fedora 9. First, everything is updated to the latest versions, including GNOME 2.22, KDE 4.0.3, and Xfce 4.4.2.

Fedora 9 introduces the new filesystem ext4 as an option. While ext4 remains an experimental filesystem, it may be good to try it out. Like ext3, it remains compatible in both directions (an ext4 filesystem can be mounted as ext3, and vice versa).

Fedora 9 also replaces the System V initd process with an event-based replacement, upstart. Upstart was created and developed for Ubuntu Linux, and has spread to Fedora and Debian. Each process is started through a response to an event, and each process may generate another event.

Fedora 9 has several different spins or variations based on different sets of packages. For example, there could be a KDE spin, a GNOME spin, and a Xfce spin for example. The Fedora project has a page tracking spins for those who might be interested in custom spins.

This version of Fedora introduces support for Jigdo, which is a CD distribution mechanism that the Debian project has used for years. I've not used Jigdo, but the description given in the release notes suggests a large speedup if you have most of the data already.

It sounds like a very exciting distribution; I'll be looking around my electronic wasteland to see where to install it.

Eh già...ogni volta a rompervi l'anima (se non qualcos'altro) con annunci di future versioni di Linux...ma stavolta la notizia è grossa: Ubuntu 9.04 abbandonerà Gnome e si munirà di KDE 4 (ecco il motivo di KDE 4 in Kubuntu 8.04). Non disperate amanti di Gnome! Dovrete soltanto limitarvi ad abbandonare il classico "ubuntu" per il nuovo "Gubuntu" (ovviamente la G sta per Gnome). In questo modo non esisterà più una sostanziale divisione tra Ubuntu e Kubuntu e quindi si pensa che rimarrà un unica distribuzione, appunto Ubuntu (kde) con l'alternativa di Gubuntu. A questo punto è lecito chiedersi se il progetto xubuntu rimarrà in vita,ma questo lo potremo scoprire nelle prossime puntate...

Pero por el momento estoy usando Gnome gracias a que estoy esperando una versió mas estable de KDE 4.

Por lo que veo hay un progreso muy bueno.

Si instalas el escritorio KDE en Ubuntu para probarlo (ver el post anterior), verás que al iniciarlo por primera vez, está todo en la lengua del imperio. Si quieres sacarte el inglés y ponerlo en cristiano antiguo, solamente tienes que abrir una consola y poner:

sudo apt-get install kde-i18n-es

Reinicias la sesión, y ya debería estar en español.

Sagen er imidlertid den at KDE er et enormt oversættelsesprojekt med mere end 115.000 tekststrenge alene i brugerfladerne - dokumentationen kommer oveni. Oversættelsesarbejdet er næsten altid blevet udført af en enkelt person med sporadiske bidrag. I mange år var det Erik Kjær Pedersen - I de sidste fem måneder har det været mig. Ikke alene skal jeg vedligeholde oversættelserne, men der er også et efterslæb efter næsten et halvt års inaktivitet, som gjorde at KDE4.0.0 blev udgivet uden danske oversættelser.

Derfor er kvalitetssikring en umulighed. Jeg er nødt til at forsøge at oversætte så meget som muligt så hurtigt som muligt. Selv hvis jeg havde tid til korrekturlæsning, ville det ikke hjælpe meget at gøre det selv, da man oftest overser sine egne fejl. Det er min forhåbning at kvaliteten senere kan hæves, når efterslæbet er endeligt indhentet. Jeg fokuserer i øvrigt ret ensidigt på KDE4.x, da der ikke er de store fremtidsperspektiver i KDE3.5.

Du kan hjælpe på flere forskellige måder.

Rapportér fejl. Skriv en e-mail til mschlander [at] opensuse.org eller kontakt "cb400f" via IRC i #dansk-gruppen på Freenode-netværket. Man kan altid finde e-mail-adresse til KDE-oversættere af hvert enkelt program på denne måde: Hjælp -> Om [program] -> Oversættelse

Fejl i KDE3.5 vil kun blive rettet hvis de har væsentlige forståelsesmæssige konsekvenser, men der er betydelig risiko for at de går igen i KDE4.x, så det betaler sig at rapportere dem alligevel.

Hjælp med korrekturlæsning. Alle oversættelserne jeg laver sendes til dansk-gruppens mailingliste hvor enhver kan tilmelde sig og give feedback.

Hjælp med at oversætte. Det er vigtigt, spændende og overkommeligt arbejde. Jeg vurderer at omtrent følgende kvalifikationer er nødvendige:

• Du æælsker KDE
• Du er habil til engelsk
• Du er habil til dansk
• Du er villig til at bruge et par timer eller mere i gennemsnit pr. uge over en længere periode

Det kan også være at du bare gerne vil stå for oversættelsen af et enkelt program, som du er ekspert i og som betyder meget for dig.

Kontakt mig via mail eller IRC som anført ovenfor.

Today I wanted to find out the contents of a QString. "print s", where "s" is a QString, doesn't do much for you, though. The data is stored as an array of ushorts inside a shared data member. But all I want is to print out the string as it would appear if I did "qDebug() << s", for example.

Solution: head over to the kdesdk module, and into the scripts directory, where mountains of useful bits reside. The script you want is kde-devel-gdb.

Now copy this to your home directory and put the line "source ~/kde-devel-gdb" into your ~/.gdbinit file. Or, if you're building KDE in the manner prescribed on techbase, you can just put "source /home/kde-devel/src/KDE/kdesdk/scripts/kde-devel-gdb" into your ~/.gdbinit file.

To use, check out "help user-defined".  For example, to print a QString called s, type "printq4string s".  Ta-da!
