Today I experienced more or less the same problem as reported hereon iBricking when upgrading using iTunes under VirtualBox. I found a way through, though. The problem is that the iPhone “disconnects” from USB during the process, and reconnects again later. Some times with a different “id”. VirtualBox does not automatically attach the iPhone again, and one has to manually watch the sync process and discover that the iPhone has disconnected. If one is quick enough (not that difficult, iTunes seems to be retrying to connect to the iPhone quite patientely), to reconnect the USB device to the virtual machine, then the upgrade can work.

It can help to have a command like the following running in a console window # watch -n 1 lsusb

The usb id’s changed something like

Recovery Mode:
xxx 1293 (I believe to remember).

Reboot (disappeard from usb bus)
Re-appearing as (you need to

during the restore to factory settings and restore from backup.

I did not receive emails, all of a sudden on my Mandriva postfix mail service. I think the reason was that postfix had not been restarted since last update, and when I restarted today (when adding my new domain wemobilize.dk) a bad change from last update got effectuated.

post delivery

The log said:

 status=deferred (connect to mail.efef.dk[/var/lib/imap/socket/lmtp]: No such file or directory)

http://lists.andrew.cmu.edu/pipermail/info-cyrus/2007-September/026838.html gave the hint to disable chrooting the lmtp service, i.e. use:

lmtp  unix    -       -       n       -       -       lmtp

instead of

lmtp  unix    -       -       y       -       -       lmtp

in master.cf.

I wanted to quickly sketch a user interface, and usually I resort to pen and paper for the first iterations, but I wanted to try a RAD tool, to see if that was quicker. I had played with SWTDesigner and netbeans, but non of them were really easy to use for this purpose — to much tied to the generality of their tool kits (SWT and Swing, respectively).

I googled for linux and RAD and found Gambas – http://gambasrad.org/. It seemed well thought out, mature and well documented, so I gave it a whirl. In four hours I had had a working demo for the concept I had in mind, including images, movies (animated gif), sounds, timers, buttons and screens.

I used xvidcap to capture a move of the demo since it by default only produces linux executables (guess it should be able to export windows executables since it can use QT or GTK+, both of runs under windows, as far as I remember).

Recommended! Do you have any other favorite RAD tools?
