This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:
$mysqli = new mysqli('localhost', '#username', '#password', '#database'); | |
$handle = fopen('sqldump.sql', 'rb'); | |
if ($handle) { | |
while (!feof($handle)) { | |
// This assumes you don't have a row that is > 1MB (1000000) | |
// which is unlikely given the size of your DB | |
// Note that it has a DIRECT effect on your scripts memory | |
// usage. | |
$buffer = stream_get_line($handle, 1000000, ";\n"); |
Possible values for ext-name: | |
bcmath | |
bz2 | |
calendar | |
ctype | |
curl | |
dba | |
dom | |
enchant |

I upgraded my iPhone 5s to iOS 10 and could no longer retrieve photos from it. This was unacceptable for me so I worked at achieving retrieving my photos. This document is my story (on Ubuntu 16.04).
The solution is to compile libimobiledevice and ifuse from source.
