Know about this?
x = [i * 2 for i in [1, 2, 3, 4]]
Be careful. The scope of “i” is not limited to the expression it is used in.

iPhone development: Bits/c++config.h: No such file or directory
Developing for iPhone with some C++ code? Suddenly getting this error after installing a beta SDK?
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.2.sdk/usr/include/c++/4.2.1/bits/stl_algobase.h:65:0 Bits/c++config.h: No such file or directory in /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.2.sdk/usr/include/c++/4.2.1/bits/stl_algobase.h
Note the bolded folder. Change into it and make a symlink from arm-apple-darwin9 to arm-apple-darwin10. Please note that Apple has fixed this already at one upgrade of beta SDK (I had this error before too, but I still didn’t get 4.0 beta 2 so I didn’t check) so it’s reasonable to assume they will do this again.
cd Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.2.sdk/usr/include/c++/4.2.1/
ln -s arm-apple-darwin9 arm-apple-darwin10
PS I don’t think posting this violates any NDA. Especially since origin for this solution is also public.
iTunes: Cannot combine songs into an album?
If you cannot merge songs into a single album, first check that their album name, artist name, and other properties match.
If these are already the same, note that sometimes “foreign symbols” may cause issues. For example, try renaming album “Mačak u vreći” to “Macak u vreci”. If this successfully combines the songs, you can try renaming the album back into its original name.
Croatian ISPs have DNS issues?
Chrome screenshot depicts “nehe.gamedev.net” as opened on Croatian T-Com ISP with their DNS. Black Safari screenshot depicts “nehe.gamedev.net” when using Google’s DNS server.
Reportedly Croatian ISP B-Net also has the same issue.
On B-Net and T-Com, nehe.gamedev.net resolves to 209.62.105.19. Ordinarily it should resolve to 216.185.96.235.
White Safari screenshots depicts what you get when you visit this IP directly. Apparently searchmagnified is not owned by NetworkSolutions because it advertises other registrars.
Could this be some well orchestrated DNS hijack? Or is it just caching gone haywire? (It seems strange that this reputable domain would “revert” to a spyware and ad-troll site and be restored so quickly, but that Croatian ISPs’ DNSs’ would go insane.)
Could it be related to this January 2010 attack against Network Solutions?
From inquiring foreign acquaintances and friends, looks like this is a local problem. Also, here’s some whois and nslookup digging.

Looks like the domain itself is pretty much doing very well! As it stands it looks like it’s truly a DNS hijack, but I’m not exactly a network expert so don’t take my word for it.
Getting GNU/Linux to reboot properly on unibody Macbook from late 2009 (Macbook 6,1)
To get a GNU/Linux to reboot properly and not hang in the final step, you need to pass another parameter to the kernel. You need to pass reboot=pci to Linux.
Currently, Debian and Debian-derivatives such as Ubuntu tend to use Grub2 as the bootloader, by default. You need to:
- edit the /etc/default/grub configuration file, as root, and using your favorite editor
- find line that looks similar to GRUB_CMDLINE_LINUX=””
- if it contained anything inside quotes, don’t delete those commands!
- into the quotes, add reboot=pci but do not delete existing text
- back in command line, run update-grub as root user
It should now work flawlessly!
