It can even updates the Flickr photos automatically. The bad thing is that this feature is turned on by default when you enable the Flickr service. The default setting is it will update to Flickr every 6 hours, and it will consumes for about 600kb of data transfer. This feature is bad for users that do not subscribe to the unlimited Internet broadband.


How to turn the automatic update feature off?

  1. Press the XpressMusic button.
  2. Select Settings (The bottom third right most icon).
  3. Select Advance.
  4. Disable Use cellular. Disable Use cellular will disallow the phone to use mobile network to connect to Flickr.
  5. Disable Roaming. The phone will not update Flickr outside when you are overseas.
  6. Select Download interval option to Manual.

To count the number of elements occurrences in a list

>>> from collections import Counter
>>> z = ['blue', 'red', 'blue', 'yellow', 'blue', 'red']
>>> Counter(z)
Counter({'blue': 3, 'red': 2, 'yellow': 1})

Count the number of alphabet occurrences in a text

>>> from collections import Counter
>>> Counter("This is a test")
Counter({' ': 3, 's': 3, 'i': 2, 't': 2, 'a': 1, 'e': 1, 'h': 1, 'T': 1})

To find the n most common words in a text

n is the number of most common words to find

For Windows, they can be downloaded from the Info-ZIP Website. This article provides the basic of archiving and compressing files using the command line zip program.


Zip one file

zip filename.zip file_to_compress

Zip multiple files

zip filename.zip file_to_compress1 file_to_compress2 file_to_compress3

Compression options

The compression level ranges from 0 to 9. Level 0 means no compression, 1 compress faster, and 9 compress better. The default is 6.

zip -9 filename.zip file_to_compress

Password protect zip archive

zip -P the_password filename.zip file_to_compress

To be prompted for password instead of specifying the password in the command line, use -e instead of -P.

zip -e filename.zip file_to_compress
Enter password:
Verify password:

Besides, Nokia 5800 also support Assisted GPS (A-GPS), and it is turn on by default.

A-GPS could help the phone to connect to the satellite faster. However, A-GPS requires the internet connection. Therefore, if you are not subscribed to the unlimited broadband package, you may want to disable the A-GPS support.

My ignorance of this issue had cost me a few hundreds Ringgit.

To disable the A-GPS support in Nokia 5800, follow this steps:

  1. Press the white Menu button.
  2. Select Apps.
  3. Select Location.
  4. SelectPositioning.
  5. Select Positioning Methods.
  6. Select Assisted GPS, and select Disable.

It will never be shown in a cell. But, is it possible to display the equal sign in Microsoft Excel?

Actually you can display the equal sign. What you need to do is just add an apostrophe in front of the equal sign, like this:

'=

Once you press Enter, the apostrophe will disappear, leaving the equal sign.

Note: To display the apostrophe, just enter the apostrophe twice.

But, what if we plug more than one thumb drive? How are we going to know which one is the one we that want just by looking at the drive letter.

Fortunately, Windows enable us to give the thumb drive a name.

To give the thumb drive a name, right click on the drive letter, and choose Properties.

In the Properties windows, we can change the name, as shown in Figure 1.

These numbers are easy to remember, nevertheless easy to be broken.

This article will give an idea on how to create a secure, but memorable PIN number.

How to create the PIN number

The technique is so simple. You need to create your own simple algorithm to generate the PIN number, based on the number that you already memorized. In case you forget the PIN number, it can always be generate easily using the algorithm.

An example of algorithm

Let say you want to generate a PIN that consists of six digits.

  1. First create the secret number. Think of a 3 digits number that you won’t forget. For example, if you are born in 1965, you can use 965 as the secret number.
  2. Use your algorithm to create the PIN number.
    Example: Add the secret number in step 1 with the number one, and multiply it back to itself.
    965 * (965 +  1) = 932190
  3. Therefore, your PIN number is 932190.

Different PIN number for different bank

Using this technique, you will have a PIN number that cannot easily be guessed by others. But, what if you want different PIN number for different bank?

You can also create different PIN number for different bank, using the same algorithm and secret number.

Just associate bank1 with 1, bank2 with 2, and bank3 with 3. Then, you can replace the number one in your algorithm with two for bank2 and three for bank3.

Conclusion

This article shows on how to create PIN numbers from one secret number and an algorithm. Using this technique you will only need to remember the secret number, the algorithm and the bank association number.
