Some Symbian application installation files downloaded from OVI Store using "Download OVI Store sis/sisx Installation Files to PC" method post appears to have ".sis.dm" as the file extension. In order to use the installation file to install to any Nokia phone, the content of the installation file need to be modified. Note: By simply renaming the extension will not enable the installation file to install to Nokia phone. Follow these simple steps and you shall get the installable sis/sisx file. By using a test editor, open the ".sis.dm" file. Once opened, you will see in the first 3 lines of the file that looks something like this: --boundary-1 Content-Type: x-epoc/x-sisx-app Content-Transfer-Encoding: binary Delete them! Delete them until before the "z" character. Save As a new file with the same filename but with ".sis" extension. The installation file is ready to install in your Nokia phone.

This is a reference on how to download an entire web site using wget program. This works for both Windows and Linux variant of the program. There are 2 ways to use wget to download a web site. Below are my recommendation of the usage of the wget command. Simple & Easy wget -m [url] Longer & More Control wget \  --recursive \  --no-clobber \  --page-requisites \  --html-extension \  --convert-links \  --domain [url] \  --no-parent Extra Tweak to Avoid Getting Ban By Server Admin Some server admins might ban the download if there are no delay in between downloads and in high speed. The extra option below will probably avoid getting ban from the server admins. --wait= [seconds] --limit-rate= [download speed in 'k']

The Disk Cleanup tool in Windows XP can be use to setup for automated runs. Setting Up Goto Start > Run Run this command: cleanmgr /sageset:1 Setup your clean up options and click OK. This will save your options setting to "1". The set numbers can be from 0 to 65535. Run The Clean Up Using Saved Setting Goto Start > Run Run this command: cleanmgr /sagerun:1 The Disk Clean Up tool will run without any interactive prompts. Automate It Below is a batch file that i have created for myself to schedule to run the Disk Cleanup tool during midnight on my office PC. -------Start Copy From Below-------- echo off echo Start at date /T time /T rem cleanmgr /sageset:1 cleanmgr /sagerun:1 echo ################################ echo # Disk clean up has completed! # echo ################################ echo Stop at date /T time /T pause --------Stop Copy From Above---------

Below is the batch file codes that i have used to schedule to run weekly during midnight on my office desktop. Although this process will take hours to run but HDD defragmentation can actually finish under an hour time if HDD defragmentation scheduled to be run every week, during lunch time. --------start copy from below-------- @echo off echo Defragmentation started: date /T time /T defrag C: -v echo Defragmentation stopped: date /T time /T pause --------stop copy before this line-----

Google does not provide a direct way to import contacts from Facebook. But Yahoo! does provide that functionality. Unfortunately, it only imports email addresses of your Facebook friends. How i wish that it could also import the Date of Birth and telephone numbers. To get the email addresses from your Facebook contacts to Google, simply import them to your Yahoo! mail contacts and transfer them to Google Contacts. Login to your Yahoo! mail. Goto Contacts. Import emails from Facebook. Export all Yahoo! mail contacts to (yahoo csv format). Login to your Gmail. Goto Contacts. Import your exported Yahoo! contacts (csv). Clean up the whole Google Contacts by performing "Find duplicates and merge" from the Google Contacts interface.

From Ubuntu Community Documentation: The swappiness parameter controls the tendency of the kernel to move processes out of physical memory and onto the swap disk. Because disks are much slower than RAM, this can lead to slower response times for system and applications if processes are too aggressively moved out of memory. swappiness can have a value of between 0 and 100 swappiness=0 tells the kernel to avoid swapping processes out of physical memory for as long as possible swappiness=100 tells the kernel to aggressively swap processes out of physical memory and move them to swap cache The default setting in Ubuntu is swappiness=60. Reducing the default value of swappiness will probably improve overall performance for a typical Ubuntu desktop installation. A value of swappiness=10 is recommended, but feel free to experiment. Note : Ubuntu server installations have different performance requirements to desktop systems, and the default value of 60 is likely more suitable. To check the sw

tmpfs is a filesystem that mounted into a Linux Operating System which uses storage space from the physical memory (RAM). The advantage of using tmpfs is to improve file reads and writes performance and reduce writes to HDD and SSD storage system. By reducing HDD writes, HDD will have more opportunities to spin down and thus saving power consumption.  By reducing SSD writes, the lifespan of the SSD can be prolong. Example: Open /etc/fstab file for editing. sudo gedit /etc/fstab Append these lines at the bottom of the file. tmpfs /tmp tmpfs defaults 0 0 tmpfs /var/tmp tmpfs defaults 0 0 tmpfs /var/log tmpfs defaults 0 0 tmpfs /var/log/apt tmpfs defaults 0 0

noatime, nodiratime and relatime are disk mount options to disable access time information updates onto every file or directory the system access. By using these options, disk writing activity can be reduce significantly. This is useful for Solid State Drive (SSD) or to encourage Hard Disk Drive (HDD) to spin down and save power. noatime - Disable access time update of files in HDD. nodiratime - Disable access time update of directories in HDD relatime - Update access time relative to modify or change time. Access time is only updated if the previous access time was earlier than the current modify or change time. Example: Open /etc/fstab for edit. sudo gedit /etc/fstab Append the options to one of the mounted drives. # <file system> <mount point> <type> <options> <dump> <pass> /dev/sda / ext4 errors=remount-ro ,noatime,nodiratime  0 0
