Αλλάζοντας τα φώτα στο Vodafone Joy

Vodafone Joy (Huawei u8120) running Android 2.3.7

Vodafone Joy (Huawei u8120) running Android 2.3.7

Το πιο φτηνό smartphone με Gingerbread 2.3.7!
Οκτώβριος 2012:
Η συσκευή Vodafone Joy άνοιξε για πολλούς το δρόμο προς τις custom ROM, λόγω τιμής και λόγω ευκολίας χειρισμού. Με μερικά απλά βήματα, μπορούσε ο καθένας να πάρει το φτηνότερο smartphone της αγοράς και να το κάνει μια αξιοπρεπή συσκευή.
Ο παρών οδηγός, πιστεύω συνέβαλε στη διάδοσή του, καθώς και στην (αυτο)εκπαίδευση αρκετών χρηστών (20.000 επισκέψεις σε 18 μήνες!) Ευχαριστώ για την ανταπόκριση. Ο δρόμος αυτού του συγκεκριμένου οδηγού όμως, έφτασε στο τέλος του, καθώς δεν πρόκειται να συνεχίσω να τον ενημερώνω.
Πλέον χρησιμοποιώ το Samsung Y Sony Xperia J και σύντομα θα γράψω οδηγίες για την… παραμετροποίησή του!  (https://laspas.gr/2013/01/12/sony-xperia-j/)
Ωστόσο, η ενότητα σχολίων θα παραμείνει ανοιχτή, προκειμένου οι χρήστες του κινητού να μπορούν να συνεχίσουν να ανταλλάσσουν ιδέες και να βρίσκουν απαντήσεις και βοήθεια.

Ιστορικό

Τον περασμένο Οκτώβριο (2010) κατάφερα να καταστρέψω το προηγούμενο κινητό μου, ρίχνοντάς το στα νερά κατά τη διάρκεια μιας βροχερής μέρας στην Αθήνα. Άρχισα λοιπόν να ψάχνω για μια σχετικά φτηνή λύση όσον αφορά το hardware. Ωστόσο, το λειτουργικό ήθελα να είναι Android, καθώς είχα στο μυαλό μου ότι θα ήθελα να ξεκινήσω να γράφω απλές εφαρμογούλες για κινητά.

Ψάχνοντας σε διάφορες ιστοσελίδες με τίτλους του τύπου «10 best budget android phones», σχημάτισα μια αρκετά καλή ιδέα όσον αφορά τις διάφορες εκδόσεις του λειτουργικού και ποιες ήταν οι απαιτήσεις του σε υλικό (πχ ότι για να έτρεχε αξιοπρεπώς η τότε πιο πρόσφατη έκδοση, η Froyo 2.2, θα έπρεπε το κινητό να έχει επεξεργαστή κοντά στο 1GHz).

Δυστυχώς, ο συνδυασμός «αρκετά καλής ανάλυσης», «αρκετά μεγάλης οθόνης», «αρκετά δυνατού επεξεργαστή» και «αρκετά μεγάλης μνήμης», κατέληγε σε τιμές που ήταν «αρκετά παραπέρα» από τον προϋπολογισμό που είχα στο μυαλό μου (δηλαδή κάτι με λιγότερο από 150 ευρώ).

Μετά από δύο απογεύματα ψαξίματος, έγινε το μοιραίο: έπεσα πάνω σε μια συζήτηση στο φόρουμ myphone.gr, ένα τεχνικό φόρουμ το οποίο θεωρώ από τα πιο ειδικευμένα, πλήρη και εμπεριστατωμένα διεθνώς. Το θέμα συζήτησης ήταν για το πρωτοεμφανιζόμενο (τότε, τέλος Οκτωβρίου 2010) Vodafone 845. Ουσιαστικά πρόκειται για μια ευχάριστα απρόσμενη κίνηση της Vodafone, η οποία κυκλοφορεί το Huawei Joy με το δικό της branding και τις εφαρμογές του δικτύου της, σε τιμή «ό,τι-έπρεπε-για-Χριστούγεννα»!

Παρακάτω θα περιγράψω με ποιον τρόπο, αυτό το πάμφθηνο τηλεφωνάκι (γύρω στα 110 ευρώ τότε) έγινε η καλύτερη συσκευή που έχω χρησιμοποιήσει ποτέ. Ευχαριστώ Vodafone!

Getting Canon Pixma MP560 to work in Mint 12 amd64 (and Ubuntu 11.10)

canon pixma mp560

canon pixma mp560

Update, December 2012

Moving forward to Mint Nandia (based on Ubuntu 12.10), Michael’s drivers in canon-trunk suport two-sided printing! At last!

Update, May 2012.

Moving forward to Mint Maya (based on Ubuntu 12.04), I found that Michael’s Canon repository did not have a driver version for Precise and that the previous ones used in Oneiric, would not work.

In order to solve this problem, you need to follow these steps:

  • Uninstall the existing canon drivers
  • Remove the existing canon repository from your sources
  • Add the new repository:

[code]sudo add-apt-repository ppa:michael-gruz/canon-trunk
sudo apt-get update[/code]

  • Re-install the drivers corresponding to your printer, with Synaptic. You may have to use the i386 packages if amd64 ones are not available. They will still work!

The perfect linux desktop (part 2): Multimedia support

In this post I’ll list and give installation instructions for the media applications that I have found most useful on my Linux Mint desktop. That should cover photo management, video and music.

1. Photo Organizer

Shotwell

Shotwell photo organizer

OK, this may come as a surprise to some, but if I were you… I’d ditch F-Spot! Really, just uninstall it. There’s a much better application that actually works, and it’s called Shotwell!! It is the default photo organizer in Fedora 13.

I really like the Shotwell project, it does what it’s supposed to do, and it does it well. There’s also a very helpful on-line manual.

The fastest way to install it, is either via the package manager, or by firing up a console and typing:

$ sudo apt-get install shotwell

If, however, you want to make sure that you’ll always have the latest version for your distribution, follow the instructions at their website (check the option for Ubuntu), which are, in short, to fire up a console and enter the code below (you can also drag-n-drop the code, from here to the terminal, line by line!!)

$ sudo add-apt-repository ppa:yorba/ppa
$ sudo apt-get update
$ sudo apt-get install shotwell

2. Video Editing

PiTiVi

PiTiVi video editor

To quote their website, PiTiVi is a free, intuitive and featureful movie editor for the Linux desktop.

For a list of features, take a look at this page. It is a fairly new project, but it shows great potential and it is already full featured and fully usable.

In order to install it, you can use the package manager, or just fire up a console and enter:

$ sudo apt-get install pitivi

In case that you want to use the latest beta version (beware, this may break things), you can add the development repository:

$ sudo add-apt-repository ppa:gwibber-daily/ppa
$ sudo apt-get update
$ sudo apt-get install pitivi

3. Video Transcoding & Converting

WinFF

WinFF 1.1.1 for Ubuntu

When it comes to video transcoding, there’s only one choice on my mind – WinFF. To quote their website:

WinFF is a GUI for the command line video converter, FFMPEG. It will convert most any video file that FFmpeg will convert. WinFF does multiple files in multiple formats at one time. You can for example convert mpeg’s, flv’s, and mov’s, all into avi’s all at once.

WinFF has many presets for output targets and it keeps getting better. You can install it using the package manager, but I recommend getting the latest version, following the procedure below (in a terminal):

$ sudo add-apt-repository ppa:paul-climbing/ppa
$ sudo apt-get install winff

This will work just fine for almost everybody. However, in order to get the absolute maximum out of this program, you may need to get the unstripped versions of ffmpeg. These libraries are available at the medibuntu repository (Multimedia, Entertainment & Distractions In Ubuntu). Please note the disclaimer from their website:

Medibuntu is a repository of packages that cannot be included into the Ubuntu distribution for legal reasons (copyright, license, patent, etc), related to geographical variations in legislation regarding intellectual property, security and other issues.

Patent and copyright laws operate differently depending on which country you are in. Please obtain legal advice if you are unsure whether a particular patent or restriction applies to a media format you wish to use in your country.

See Ubuntu’s Free Software Philosophy and the FreeFormats page for a more comprehensive discussion of these issues.

If you decide to add this repository to your system, give the following commands at a terminal and then do a [code]sudo apt-get update; sudo apt-get upgrade[/code]

Replace $(lsb_release -sc) by the corresponding release of Ubuntu in Linux Mint (click here for the Mint name corresponding to each Ubuntu release). For example, if you are using Linux Mint Isadora, replace “$(lsb_release -sc)” with “lucid”:

$ sudo wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list && sudo apt-get --quiet update && sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring && sudo apt-get --quiet update

$ sudo apt-get --yes install app-install-data-medibuntu apport-hooks-medibuntu

4. DVD Ripping

There are three apps that I like for the task of DVD ripping: AcidRip, DVD::Rip and K9Copy!

AcidRip

acidrip

For AcidRip, just go to the package manager and install it, pretty straightforward.

To quote SourceForge:

AcidRip is an automated front end for MPlayer/Mencoder written in Perl, using Gtk2::Perl for a graphical interface. Makes encoding a DVD just one button click!

AcidRip is by far the easiest app for ripping DVDs. It’s main advantage is that, most of the times, in order to encode a DVD into avi, it really only takes one click!

DVD::Rip

dvdrip_clip_zoom

DVD::Rip is an old-school application, at least as far as appearances go. A newbie may easily be intimidated by the user interface, but all in all, it is the most capable ripper. Anything you can imagine that a DVD ripper should do, it does it. You can install it from the package manager.

Just for the fun of it, check out the features list at their website. It’s quite long!!

One final note: in order to get maximum results when handling encrypted DVDs that you have bought and wish to back up, it may do better after you install the library libdvdcss2.

This is a library that you may find at medibuntu, so read the disclaimer and the relevant info further up in the post. You will be able to install libdvdcss2 after you have activated the medibuntu repository.

K9Copy

k9copy_screenshot

Another great application for backing up your DVDs is K9Copy. It is very similar in functionality to the windows program DVDShrink.

You can compress a 9gb DVD so that it will fit on a 4.7gb disk, preserve original menus and even choose which languages or subtitles to back up or leave out. You can also set the output to be an avi or an iso file.

5. CD Ripping

GRip

GRip in action

There’s only one app that I like here: GRip! This is the best app I’ve ever used in order to back up my CDs.

Features list:

  • Full-featured CD player with a small screen footprint in “condensed” mode
  • Database lookup/submission to share track information over the net
  • HTTP proxy support for those behind firewalls
  • Loop, shuffle, and playlist modes
  • Ripping of single, multiple, or partial tracks
  • Encoding of ripped .wav files into MP3 files (as well support for OGG and FLAC)
  • Simultaneous rip and encode
  • Support for multiple encode processes on SMP machines
  • Adding ID3v1/v2 tags to MP3 files
  • Cooperating with DigitalDJ, my SQL-based MP3 jukebox

6. Audio Editing

Audacity

audacity-linux

In my experience, there is no sound editor with so many features, that is so easy to use, at the same time, as is Audacity.

The features list is too long to post!!

7. Music Player & Organizer

Amarok

amarok-2.3.1

For a long time, Amarok (“Wolf” in Native American) had been the only reason for which I had KDE libraries installed on my Gnome machine. Up until 2008. That’s when version 2.0 came out, which I then thought was the worst thing that could happen to the project. Partly because it was completely unusable, partly because I could really not see where the poet was going with it (coding is poetry, right?).

I then tried several other solutions, among which I have to say that Exaile was the next best thing.

Over time, however, Amarok got back on track, and it is now, once again, the only reason for which I keep KDE libraries installed on my Gnome machine.

With Amarok, you will really rediscover your music. Really.

Oh, and by the way, it also has a built-in equalizer!!!

You can install it from the package manager and you’re good to go. However, what kind of geek would you be, if you did not follow the instructions below?

$ sudo add-apt-repository ppa:kubuntu-ppa/backports
$ sudo apt-get update
$ sudo apt-get install amarok
$ sudo aptitude install phonon-backend-xine

In case you have a “need for expeditious velocity”, you can follow the instructions from this excellent post, in order to have Amarok use MySQL as a back-end database. Combined with the embedded help from Amarok itself (in database settings), you get the following example. Replace with your own data and run in a terminal:

[code]sudo apt-get install mysql-server mysql-client[/code]

This will install the database. Make sure you set an administrator password when asked. Then, enter these commands (don’t you just love how efficient the terminal is? :P)

[code]mysql -p -u root
CREATE DATABASE amarokdb;
GRANT ALL PRIVILEGES ON amarokdb.* TO ‘amarokuser’ IDENTIFIED BY ‘password’;
FLUSH PRIVILEGES;
quit[/code]

Finally, fill in the same data in Amarok’s database settings, restart MySQL, then restart Amarok set it to completely rescan the music folder.

Amarok’s functionality can be expanded by scripts. For example, in order to have a nice list of Greek radio stations streaming through Amarok, you can install this script. Just go download and then install through Amarok’s script manager.

Update, November 2010
