Generally, if you plugged a USB modem to a Linux, it identifies the modem, as a USB Storage device. So due to that you can't access internet through your USB Modem.

First you must check whether the  usb-modeswitch is  already   installed in your system.  For that open Terminal and type sudo usb_modeswitch  .

Department for Persons Registration of Sri Lanka

Image
Yesterday I went to the Department for Persons Registration to get new NIC for my lost NIC. I reached there at 9.00 AM. I had to stand in a long que for about 30 minutes. Then they gave me a number card and they told that they will call me to the counter according to that number. They called me at 11.30 AM. I paid the fee. When I gave my file I told them, there is a correction to be made in my name. They told me that it is not a problem, we enter your name as it is in the birth certificate. Then I was standing for a long time, and at last they announced my name at 3.30 PM. Finally I got my NIC but my name was not corrected. What they did was, they copied the details from my old NIC and pasted it in the new card. (CTRL+C, CTRL+V)

Java Byte Code, Interpreter and JIT

Image
Generally, when a program is compiled to an intermediate level and then interpreted  by a virtual machine, it runs slower than it would run if compiled to machine code. However, with Java, the differential between the two is not important for general purpose. Because byte-codes are highly  optimized, the use of byte-code enables the Java Virtual Machine to execute programs much  faster than you might expect. Java is also designed as an interpreted language, so java does not have anything to stop  (on the fly) compilation of byte-code into machine code, to improve  performance. For this reason, the HotSpot technology was introduced after Java’s initial release. HotSpot provides a Just In Time (JIT) compiler for bytecode. When a JIT compiler is part  of the JVM, selected set of bytecode are compiled into executable code in real time,  on a piece, by, piece, demand basis.  It is important to understand that it is not practical to  compile a whole Java program into machine code all a
