Ring Tones in Android

To be able to add and change the ring tones in Android follow these steps:

-To calls: create a folder named "ringtones";
-To messages (notifications): create folder named "notifications";
-To alarms: create folder named "alarms".

I create the folders in "/sdcard/media/audio".

Just put the files .mp3 in the respective folders and the new ring tones are available in the selection lists.

HP Photosmart C4280 Cartridge Problems

If you have an HP Photosmart C4280 Printer, HP might try to rob you… on ink cartridges. If the printer displays a message:

Print cartridge(s) missing or not detected.

It doesn't mean that! You might think that the cartridge is empty or damaged. You couldn't be more WRONG! It just means that HP wants YOU to BUY a NEW CARTRIDGE - but DON'T DO THAT! You cartridge is presumably fine!

Actually you can try to convince the printer that the cartridge is ok by entering the service mode. To do that press buttons in the following sequence:

• Power and Cancel simultanously, then
• Blue, Green, Gray buttons, in turn.

Congrats! You entered the service mode. Now you can read and edit some of the printer settings. Watch the LCD display, it should say sth like:

Support
PlxxFN0724AR

Now, the color buttons mean:

• Blue: next
• Gray: previous
• Green: enter

Which allow you to browse the menu and options.

In order to cure your cartridge press Blue once. You will see Information Menu displayed. Enter the menu by pressing Green. Go to Pen supply, level of Ink (LOI) submenu by pressing 11 times Blue and enter it by pressing Green. Then you can see some ink levels on the display. At this point your job is done. Press Cancel 3 times – it will quit the service mode. And you will notice that the nasty message about the cartridge being missing is gone.

Putting it all together, to reset the message press:

• Power and Cancel simultaneously,
• Blue, Green, Gray, in turn,
• Blue
• Green
• 11 times Blue
• Green
• 3 times cancel.

I found these service codes on the web and accidently i figured out that viewing the ink level resets the nasty message. The drawback is that you need to reset the printer pretty much every print job.

partilhar entre OSX e Ubuntu com VirtualBox

• Com a máquina virtual desligada, selecione a máquina e vá em Settings > Shared Folders
• Adicione um new folder, em Folder Path coloque o caminho da pasta que está na máquina host. Em Folder Name dê um nome para a pasta
• Por exemplo "Share"
  
• Clique em OK e inicialize a máquina virtual
• No ubuntu, crie uma pasta para montar o share.
• Por exemplo "Share"
• Abra o terminal e digite "sudo mount -t vboxsf FolderName PathToMount"
• FolderName é o nome que foi escolhido para a pasta no segundo passo e PathToMount é o caminho do folder criado no ubuntu.
• Por exemplo: mount -t vboxsf Share /home/my_user_name_here/Share

Para não estar sempre a escrever o anterior:

• in Terminal: sudo gedit /etc/fstab
• add to the end of my fstab file
• "Share /home/my_user_name_here/Share vboxsf defaults 0 0"
