Currently, due to an API change ssh2 will not install via pecl. Despite being a one-line fix, and 5.3 being out for some months now, the maintainers have neglected to make their extension compatible with PHP 5.3
If you recieve an error similar to:
1 2 | /tmp/pear/download/ssh2-0.11.0/ssh2.c:52: error: duplicate "static" /tmp/pear/download/ssh2-0.11.0/ssh2.c: In function "zif_ssh2_methods_negotiated": |
Then you are affected. To fix this, you need to download and extract the ssh2 package:
1 2 | pecl download channel://pecl.php.net/ssh2-<version> tar xvf ssh-<version>.tar |
Open up ssh2-<version>/ssh2.c and look for the following block around line 50:
1 2 3 4 5 6 7 8 | #ifdef ZEND_ENGINE_2 static ZEND_BEGIN_ARG_INFO(php_ssh2_first_arg_force_ref, 0) ZEND_ARG_PASS_INFO(1) ZEND_END_ARG_INFO() #else static unsigned char php_ssh2_first_arg_force_ref[] = { 1, BYREF_FORCE }; #endif |
From that block, you need to remove the first “static” so it looks like this:
1 2 3 4 5 6 7 | #ifdef ZEND_ENGINE_2 ZEND_BEGIN_ARG_INFO(php_ssh2_first_arg_force_ref, 0) ZEND_ARG_PASS_INFO(1) ZEND_END_ARG_INFO() #else static unsigned char php_ssh2_first_arg_force_ref[] = { 1, BYREF_FORCE }; #endif |
After you’ve done this, simply repackage and install:
1 2 | pecl package package.xml pecl install -f ssh2-<version>.tgz |

Often when performing system administration, you will come across a command that needs to be run as a more priviliged user. Depending on what operating system you use, the procedure for opening an elevated command prompt varies. Read the rest of this entry »

Sometimes, you can end up with multiple copies of a directory from different times. If the number of files is small, then comparing the contents is easy. With large directories, telling the difference between them can be nearly impossible.

Sometimes, when messing around with domain names (the DNS system), you’ll mis-type an address, and be unable to access your site for a significant length of time. Assuming that the incorrect entry has not been cached on another DNS server somewhere between you and your host, you can clear the list of cached addresses on your own machine to resolve the problem.
Mixing C++ and Objective-C code using XCode

With the release of the iPhone SDK and the growing popularity of OS X, Objective-C is becoming the language of choice for a significant amount of projects.
One inescapable fact in the programming world is the existence of legacy code. Moving to a new language typically means porting or rewriting existing code entirely in the new language. In the case of Objective-C, most existing C and C++ code can be used directly.
Deploying a KIWI CD/DVD image created with KIWI to a USB drive

KIWI is a new tool released by the people behind OpenSUSE for creating customised distributions. One of the best features of it is that the images created are portable. However, documentation is scant at this time, and the instructions for deploying an ISO image onto a USB device are buried deep in the manual.
The actual process for copying the file is simple, however, identifying the right drive can be tricky.
