Nokia E71 and E63 are great phones, operating on Symbian S60 series operating systems. Its keyboard is easy to type, the LCD is sharp, the keys position are great and most importantly, the battery last long enough, approximately 5-7 days for an average user like me. The phone also comes with a lot of practical applications, e.g. word processor, spreadsheet, simple note pad, email client and etc.

The phone’s operating systems is also able to upgrade from a normal PC or laptop with USB connectivity. The last upgrade my phone had have significantly improve the responsiveness and also some functionality. e.g. typing the phone book entry on the Home Screen will directly search for it (rather the usually need to access the phone book before able to search), press shift twice will activate the secondary input language and others.

Square any 2 digit number ending in 5.

For example, let’s square 25.

Step 1: Take the first digit and multiply it by itself plus 1. So 2 x 3 = 6.

Step 2: Take the product from Step 1 and concatenate it with 25 on the right to get 625.

Let’s try again. Square 65.

Step 1:  6 x (6+1) = 42.

Step 2: Append 25 to the right of 42 and you get 4225.

Multiply any two digit number by 11.

For example, let’s multiply 78 x 11.

Step 1: Take the number being multiplied by 11 and add the digits together.  So 7 + 8 = 15.

Step 2: Insert a zero between the same two digits.  708.

Step 3: Add the result from Step 1 to the zero of Step 2. In this case we have 15, so we need to carry the 1. An easy way to think about it is 70 + 15 = 85 with the 8 from 708 added at the end for 858.

We call The Rule of 72 (or 69.3 or 70)

If you invest in the stock market and expect your money to earn a return of 5 percent per year, how long will it take for your money to double? If a VC is managing $100 million and limited partners expect a 25 percent annual return, how often do they need to double their money?

The Rule of 72 is a linear approximation — one of the coolest applications of derivatives for the pragmatic businessman. Here is a simple derivation for those of you who care.  For everyone else, simply divide the expected (compounding) return into 69, 70 or 72 to find the number of periods it takes to double. So it will take us roughly 14 years to double our money at a 5 percent expected annual return and the VC will need to double his fund every three years or so in order to hit the target return of his limited partners.

Unless you’re a Firefox power user, you may not be familiar with the about:config page. The Firefox about:config page is not so much a page as it is a somewhat hidden configuration section.

It’s hidden because it’s fairly powerful and not nearly as simple to use as the standard Preferences window. In the about:config page, you have to know what you are doing or you can mess things up a bit. In fact, when you attempt to go to that page for the first time, you have to accept an agreement (which is really just a warning) before you can continue.

How this page works is simple. You reach the page by entering about:config in the address bar. There are entries (one per line) that handle various types of configurations. Each entry has a searchable keyword. The entries can be of Boolean, integer or string value. Entries contain Name, Status, Type and Value. Typically, you will be modifying only the Value, by double-clicking on it and making the change. With all of that in mind, let’s take a look at 10 of the best ways you can “hack” the about:config page. Read more…
