Wirelessly data synchronize on Android to PC

With the increasing activity of using a smartphone of course the more data we have stored in your phone. We certainly do not want to lose data or file. One way is to backup the data on the phone and the PC. Apple's iPhone has iTunes which works very well in the syncing data and applications with a PC or Mac.

And what about the users of phones-based Android? So far no one special software that can perform backups and syncing job that runs on all kinds of Android phones. During this time, the software used separately and there may be many ways of confusing choices.

Now, the difficulty Android phone users will be resolved by the presence of Cloudless Magic Media Transfer application. These applications can synchronize with either using a wifi connection.

For a successful transfer of data between your Android device and computer, you just need to verify that you the two are connected to a similar Wi-Fi network. In addition, the option for remote sharing needs to be enabled on both computers. After fixing the necessary settings, all you need to do is access Cloudless on your Android. Then you will have to add the required computers.

To do this, you need to:
1. Tap Settings > New
2. Specify the type of sync you will do on the Account Setting screen. Modify settings for Direction, Username, Password, and Workgroup. This is also where you will be adding all users for the sync to be successful.
3. Tap on Shared Folder so you can choose the desired computer and network directory where the sync will be established.
4. Specify what type of file you will be transferring. There will be a number displayed on the Low watermark field. This depicts the number of available MB you need in your SD card storage. If you don’t have enough free space on your SD card, the app will automatically stop transferring files.
5. When you’re done choosing the file, simply tap Verify.

The good thing about opting to go Cloudless is that your data gets automatically synced to all devices added on your list. This happens when you connect to your Wi-Fi network. One thing to note though, is that you need to keep organizing transferred files on your device so you don’t clutter data on the directory. To access your transferred videos and images, you simply have to access it from the Gallery. On the other hand, your mp3 files can be accessed from within the Music app.

If you wish to manually sync data, simply tap on Transfer button found on the homescreen of the app. Be warned that the time required to successfully sync all content will depend on the amount of data and number of added users synced to your device. While the sync is ongoing, you are free to view the status of all uploads and downloads through the notification.

It is important to remember that the app is still on its alpha release. As such, it can be expected that there will still be some things that need to be fixed. One of the things that need to be modified is its interface. There should also be an option for removing a user/computer from a list as well as deleting original file after it has been successfully uploaded. A better support for the notifications can turn Cloudless into an extremely handy app.

Guide to buy the Memory Card Reader/Writer

The device of this one as important as the memory card. Important because it helps us to move data from memory card to your PC or vice versa. All the data we have the photos, work files, school work, could easily switch places because the memory card reader/writer of this.
If we do not have it, try carefully before buying. There are many types and brands of memory card reader/writer is available in various places. What should we expect?

1. Read info specifications listed in product packaging

On certain products are clearly given any memory card that can be read by a card reader and up to how much capacity memory card is capable of reading data. Read the specifications stated on the product packaging. Generally, for products like memory cards are not available manuals, specification information can be easily found on the front and back of packaging products.

2. Is there a card slot compatible with memory cards that we have.

For example, a memory card that we have the type CF (Compact Flash) then look for a memory card reader that provides a slot for CF. Generally the products listed how many card slots are available for various types of memory cards.

3. Buy a memory card that can read many cards in a certain slot, and multi-card read data simultaneously.

There is already a Memory Card Reader/Writer product that is able to read many types of memory card in one slot. For example, a slot can read the two types of cards, Micro SDHC, and a Micro SD (T-Flash). Or a slot that can read data from SD card, SDHC, Mini SD, Mini-SDHC, MMC, and others. Features multi-card reading at the same time would make the job move data becomes easier and faster. There are three types of memory card reader is a single card (1x SD), multi-card (eg 9 in 1), series cards (eg 4x SD)

4. Note the maximum data capacity that can be transferred according to the information contained on product packaging.

My experience, when I want to do the transfer of data using a memory card could not be because the storage capacity of my SD memory card, is a 4 Gb while the memory card reader / writer that I would use only able to accept SD memory cards up to 2 GB maximum.

5. Note also the connection interface

On products that are more recent than previously generally been using a USB type interface 2.o. The transfer of data to use the maximum speed if the memory cards and PC / Mac are both already have a suitable interface connection.

Did you know:
* USB 2.o has a data transfer speeds up to 480 Mbps, 40x faster than USB 1.1 which has a maximum speed of 12 Mbps.

6. Buy as needed

Have you already need a slot for reading data from mobile phone SIM card? If not needed, then the slot is not necessarily exist on the memory card that you will buy. Buy as needed, so you can save money. On certain products targeting the more price-conscious consumers, generally base material product, a USB connector cable is also not too strong and resilient. Consider this before buying, whether the memory cards will be used for "heavy duty" with the routine use every day to transfer the data of thousands of photos, hundreds of Gigabytes of data with the amount, or only occasionally move the photos over the holidays or your favorite mp3 song.

Important note:

Note the location or position when installing the memory card in card slot. If you have not entered your usual misplaced or have not exactly true. Do not be forced to convert because it will damage the foot of the connector or the connector on the card or in part in the card slot memory card reader. In general, memory card reader has been given the image guide mounting the memory card.

For those of you who have experience of the use or want to share a story about a memory card and memory card reader please give comments at the bottom of this article. Thank you.

Tips to block porn sites on mobile phones

Almost all mobile phones can now be used to access the Internet. Especially since social networking sites so loved. Advanced mobile phone owners are no longer confined to adults because many elementary level students use it too.

If Internet access is used to access the site about the lesson, maybe not a problem. But who can guarantee not go accessed pornographic sites. Although the operator on the SIM card already block porn sites but when the Internet on mobile accessed via WiFi, porn sites can be accessed without a hitch.

If it happens, is it possible to block porn sites whose numbers have thousands? Of course there are many paths. One way is to block via the browser used. Want to know step by step, follow the instructions below.

• Basically, block porn sites as well as blocking advertising sites (adds). You can create your own script which contains a list of url's that you want to block and then make the files urlfilter.ini.
  Then the files are placed where the browser application is located. For example, using the Opera Mobile browser 10.10.
  
  
• If you do not want to be bothered in making urlfilter.ini file, the file can be downloaded here. Well, the files are then copied or placed in the folder where the installation location of the Opera Mobile.
  
  
• If you want to add a list of sites, for example http://*porn.*, before opening it with notepad, there are special steps. In Windows Explorer folder options, check the option 'hide extentions for known file types' should be removed. Because when the script is added and the file on save, the format will be a .txt. So, .txt format must be converted back into .ini.
  
  
• The next step is to move files urlfilter.ini was on the phone. On the Symbian phones, if the installation of Opera Mobile on the memory card, the folder is located in E:\system\data\OperaMobile
  Meanwhile, when the installation on the phone memory, the folder located at C:\system\data\OperaMobile.
  
  
• Transferring files can be done in several ways. First, when using a card reader via PC, you can use windows explorer (Windows OS).
  Meanwhile, when directly on the phone, you need an application similar to windows explorer like LCG X-plore because this process can not be done if only using the 'file manager' standard mobile phone.
  
  
• Now you can try and see the difference. For example, when not filtered, the look of a site will appear as usual. Meanwhile, after filtered, the display site will not open at all or popup window will appear 'service unavailable'.
