Tanpa disadari, foto-foto digital yang kita posting di sebuah blog atau situs komunitas memiliki data-data pribadi. Data ini tersembunyi di balik sistem. Jika salah penggunaan, data yang dibawa foto bisa langsung mengungkap siapa anda.
Itulah yang disebut Metadata. Banyak macamnya, mulai dari data EXIF, IPTC, XMP dan Comments. Semua merupakan data tersembunyi yang mengandung informasi penting yang kadang terlalu pribadi untuk dibagi-bagi. Terlebih saat ini, ketika ponsel sudah memiliki receiver GPS internal, kadang lokasi pengambilan gambar pun ikut tercetak dalam foto kita itu.
Untuk anda yang menganggap ini sebagai suatu yang sangat pribadi, ada beberapa cara yang bisa dilakukan, misalnya menggunakan Photo Detagger dari Tea Vui Huang. Berikut langkah-langkahnya :
Langkah 1 :
Download aplikasi baru yang disebut Photo Detagger di http://teavuihuang.com/photodetagger/PhotoDetagger.jar
Aplikasi ini berektensi java dan hampir kompatible untuk semua ponsel J2ME MIDP 2.0 dari pabrikan Nokia, Samsung dan Sony Ericsson.
Langkah 2 :
Buka aplikasi. Program akan segera membaca semua file gambar yang ada dalam sistem. Terutama file tempat penyimpanan default hasil kamera foto.
Langkah 3:
Klik Option, lalu pilih Check Photo
Anda akan menemukan halaman berisi informasi foto yang dipilih.
Langkah 4:
Klik detag photo untuk memulai proses penghapusan metadata foto yang dipilih. Prosesnya berjalan cepat atau sedikit lambat, tergantung besar file. Setelah selesai muncul notofikasi kurang lebih seperti ini “EXIF photo tags have been removed”
Langkah 5:
Klik OK. Lalu perhatikan perbedaan yang terjadi. Tags EXIF akan hilang dan besaran informasi menjadi 0. anda tidak perlu khawatir akan kehilangan file asli.
Photo Detagger bikinan Tea Vui Huang ini tidak menghapus file asli, tetapi membuat file baru dengan nama sama yang ditambahkan kode tiga angka berurutan sesuai dengan urutan pengerjaan.
Good Luck !!

Manajemen iPod dengan Amarok (PCLOS)
First the problem... This is a Windows iPod with a vfat filesystem. As received, the iPod would automount and I could see it in Konqueror and seemingly add music to it using Amarok.
The problem was when unplugged the iPod didn't think it had any songs. Searching on the web led me to this procedure.
Connect your iPod with the usb cable. Type the following as root in a terminal:
lsusb -v | grep -i Serial
Among other output you will get a line looking like 000A1234567891231.
Copy this line.
Navigate to your_iPod/iPod_Control/Device folder and open the file called SysInfo. Paste the line to the file but append FirewireGuid: so that it finally looks like
"FirewireGuid: 000A1234567891231"
Save and exit.
This allowed me to send and remove songs, and album art with the iPod. The next issue is with eject. The web is full of dire warnings about ejecting your iPod before removing it for fear of corrupting the filestructure. For me, Kde was requiring root privileges to eject the device. This was easily done from konsole but I wanted to use the configurable disconnect button in Amarok. This is what worked for me. As root using kwrite I edited my /etc/sudoers file to include this line "ALL NOPASSWD: /usr/bin/eject /dev/sdb"
This allows anyone to eject /dev/sdb without a password. One would have to modify the above command to reflect where their device is mounted.
So, the config of my disconnect button in Amarok is "sudo eject /dev/sdb"
Hopefully, this will help someone get their iPod working with Amarok in PCLinuxOS.
Edit: Since I posted this I have been cautioned that if one had several USB devices and plugged and unplugged them in a changing order my eject command might be not be specific to the iPod only. I've been doing more testing and though I've been told removable media devices do not use /etc/fstab for instructions this works for me.
I include this line in /etc/fstab:
"/dev/sdb /media/ipod vfat rw,user,noauto 0 0"
I also changed my line in /etc/sudoers to:
"ALL ALL= NOPASSWD: /usr/bin/eject /media/ipod"
And finally, as you might have guessed I changed my disconnect button command to:
"sudo eject /media/ipod"
Testing with a USB stick and the iPod both plugged in shows this command to eject the iPod (no password) and the USB stick is still available.
Can I transfer my album art or videos?
Album art works for me. I think you need to have it in your Amarok collection before you transfer to your iPod. In your collection, drill to the song. There will be an icon that looks like a jewel case. Right click and choose get album art. Pick the one you like then transfer that song to your iPod, the art will come along.
If you have songs with no art you may have to delete the songs from your iPod, get the art, then transfer it back to the the iPod. I've been able to get video on and off the iPod like this.
First get gtkpod, ffmpeg, and winff from Synaptic.
Take some video from whatever source: if you're ambitious you could rip it from a DVD with DVD::rip
Point winff at it as the source. Choose one of the iPod choices in the 'format to convert to' drop down box. Let it do it's magic, then use gtkpod to send it to the iPod. One could use gtkpod for all iPod management, but I prefer the Amarok interface. Unfortunately, Amarok
doesn't seem to be able to transfer video to the iPod. Have Fun!
