AppBackup 2.0.2 released!
AppBackup 2.0.2 is out and fixes the following issues:
- Fixed a bug with translations where if something wasn’t translated then nothing would appear in the UI (expected behavior is that the English text would appear instead).
- AppBackup no longer crashes if backuptimes.plist is corrupted or malformed.
Also, the Czech, Japanese, and Korean translations have been updated. The new version should be on Cydia soon.
AppBackup 2.0.1 released
AppBackup 2.0.1 has been released and should be on Cydia soon. It fixes the bug where the app was hanging on the Please Wait screen.
Changes:
- Fixed the problem where AppBackup was hanging on the Please Wait screen for many people.
- Fixed a cosmetic bug with the Please Wait screen.
- Updated Spanish translation.
- ini-to-strings.py now sorts the list of language files before converting them.
AppBackup 2.0 is finally finished!
After a long wait, the new version of AppBackup AppBackup 2.0, is finished and has been submitted to BigBoss. It will show up on Cydia within a day. Here is what has changed in 2.0:
- AppBackup now works on iOS versions 4.3.x and later (and it still works with iOS 3; untested on iOS 2).
- Added a confirmation screen for all actions.
- Redesigned About screen.
- AppBackup has been split into two parts:
- The GUI, written in Objective-C this time.
- A command-line interface in the form of a Python package. (Just type
appbackupat the terminal to use it.) - As a result, the code has been completely rewritten and is much cleaner and object-oriented.
- The FixPermissions utility can now be used by typing appbackup-fix-permissions at the terminal. It is still run automatically in the GUI mode only.
- Updated translations and added new translations for the following languages:
- Czech - Jan Kozánek
- Chinese - goodlook8666
- Greek - Spiros Chistoforos-Libanis
- Japanese - Osamu
- Korean - Joon Ki Hong
- Norwegian - Jan Gerhard Schøpp
- Changed translations format in the source tree.
- Translations are now managed on Transifex (https://www.transifex.net/) and converted to Apple’s Localizable.strings format at build time.
I would like to thank everyone who has been patient while I was working on fixing AppBackup, and I am very sorry it took so long.
AppBackup 1.0.14 is released
I have released AppBackup 1.0.14. This is a SECURITY UPDATE. You should update AS SOON AS POSSIBLE in order to keep your device secure.
AppBackup still does not work on iOS 4.3.x; however you should still update for security reasons. I am in the process of rewriting AppBackup so that it will work on iOS 4.3.x, and I am very sorry for the long wait.
Download or wait for it to show up on BigBoss.
AppBackup 1.0.13 released
I’ve released version 1.0.13 of AppBackup, which brings the following changes with it:
- Added the ability to ignore and un-ignore apps in the backup list and when using the All button.
- Fixed a crash caused by an error in the Dutch translation. (Tim van Neerbos was consulted about the problem string. This bug only affected users who have their language set to Dutch.)
- The unique bundle ID of each app is now displayed under its name in the backup/restore prompt.
Download or wait for it to show up on BigBoss.
"Address already in use" error when OpenVPN is NOT running
So for the past week or so I’ve been trying to set up a dual-stack-payload OpenVPN server. I was playing around with some IPv6 route settings earlier when it started doing this:
$ sudo openvpn /etc/openvpn/server.conf
Wed Aug 31 02:41:06 2011 Herp derp, herpity derp derp...
Wed Aug 31 02:41:06 2011 TCP/UDP: Socket bind failed on local
address [AF_INET]64.71.167.212:1194: Address already in use
Wed Aug 31 02:41:06 2011 Exiting due to fatal error
$ echo "OH FUCK WHY WONT IT WORK!!!!1!1one!!1!"
OH FUCK WHY WONT IT WORK!!!!1!1one!!1!
$ cat /etc/openvpn/up.sh

sysctl -w net.ipv4.ip_forward=1
sysctl -w net.ipv6.conf.all.forwarding=1
ip link set $dev up promisc on mtu $tun_mtu
brctl addif br0 $dev
iptables -t nat -A POSTROUTING -s 10.4.4.0/24 -o eth0 -j MASQUERADE
service radvd restart

$ sudo lsof -i ":openvpn"
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
radvd 2486 root 6u IPv4 12816 0t0 TCP srwz.us:openvpn (LISTEN)
radvd 2487 radvd 6u IPv4 12816 0t0 TCP srwz.us:openvpn (LISTEN)
WHAT??? radvd is listening on OpenVPN’s port?
Some background: I was restarting radvd in the up script because it’s set to advertise on tap0, but tap0 doesn’t exist when the system boots, so instead of messing with the init scripts, I decided to just restart radvd in the up script. However, since the up script is executed as a subprocess of OpenVPN, it apparently inherits OpenVPN’s sockets, and radvd in turn inherits the shell script’s sockets, causing problems when you restart OpenVPN (even with SIGHUP, I would assume). *
Now I do have IgnoreIfMissing on; in my radvd.conf file (it’s not the default
yet in the radvd 1.7 that ships with natty), but I didn’t realize that starting
radvd succeeded when tap0 didn’t exist, which is why I was doing it in the up
file. radvd rereads its config file on SIGHUP, so to fix the issue, I simply
changed this line in the up script:
service radvd restart
to:
kill -HUP `cat /var/run/radvd/radvd.pid`
and restarting OpenVPN worked again.
Time to go to bed now. I hope this helps someone.
* Disclaimer: I don’t have 200 years of UNIX experience like some people do, so I may be a little bit wrong about this. But I’m probably right. :)
Forcing DD-WRT to use the desired DNS server
I should NOT have to add
server=74.82.42.42
no-resolv
to my DNSMasq config in DD-WRT in order for it to use the DNS server I want it to and NOT my ISP’s DNS servers with their lack of IPv6 Google and spamming queries for non-existent domains. And yes, I did set the DNS server on the main setup page.

OpenVPN 2.2.1 + IPv6 Payload Patch for CyanogenMod 7.1 RC1
I’ve ported Gert Döring’s IPv6 payload patch for OpenVPN to CyanogenMod. I want to try to get it into the CM source tree someday, but here are the goods in the meantime.
- Binary built for the original CDMA Droid (sholes) on 2011-08-26
- Install to your phone as
/system/xbin/openvpn. - Change owner and group to
rootand permissions to0755. - May work on other ARM phones running CM, although I haven’t tested it on any of them except my Droid 1.
- May not work on other Android ROMs because the paths to ifconfig/route/ip are configured at compile time.
- SHA-256 sum
- Install to your phone as
- CyanogenMod patch (valid as of 2011-08-26)
cd /path/to/cm/source/external/openvpnzcat /path/to/openvpn-2.2.1-ipv6-cm7.1rc1-20110826-1.patch.gz | patch -p1- SHA-256 sum
- GitHub fork of CyanogenMod/android_external_openvpn
- I had to rebase Gert’s patch for OpenVPN 2.2.1. Here it is.
Enjoy! I will not provide support for any of this, so use it at your own risk and don’t come crying to me if it hacks your Facebook and changes your relationship status or something. I really can’t help you with that. :P
Adventures in the Evil Land of iTunes
I was in the U.S. iTunes store in my Windows VM, fruitlessly searching for the album for Ludovico Einaudi’s 2007 iTunes Festival performance (I was using iTunes only because it’s from the iTunes Festival; I avoid anything made by Apple to the fullest extent possible), when I found this:
I was wondering why it would show up in the search results for Einaudi, so I clicked on it only to find this:
Of course, it doesn’t show the full track names in a tooltip, so I go to the Web page for it. Of course, it doesn’t show tooltips either, so I fiddle around with the CSS a bit to widen the column and see this:
I looked back at the page in the iTunes app and noticed that track five is the only popular song on the album. After seeing the full name of the track, it’s little wonder why! XD
P.S. It’s a beautiful album; you should listen to it! (Through a place other than iTunes, of course!) You should also read Anton Batagov’s write-up about his inspiration for the album. (Also, track 4 should say “Arvo Pärt”, not “Arvo Part”.)
P.P.S. Why the fuck do I have to set up a proxy in Ireland hunt down
an obscure music store in New Zealand in order to buy Ludovico’s 2007 iTunes
Festival album‽‽‽
P.P.P.S. Einaudi’s 2013 iTunes Festival concert is fucking epic. If only it were lawfully available for download, and outside of iTunes….
Update (2013-10-02): I was able to get Ludovico’s 2007 iTunes Festival, finally. It only took about six hours of Googling in order to find a music store in New Zealand that didn’t check my billing address to see if I’m in the right country, and then I had to wait about 12 hours for them to manually release the order, and even then their download page was buggy. I really wish the record labels would get their shit together. I should probably do a more detailed blog post about all the troubles I’ve had getting Ludovico’s full discography and how his record labels (yes, he’s actually signed to more than one label) are fucked up.
