Connect Huawei Modem Linux - USB Modeswitch

When you connect a USB modem to a Linux system, it often identifies the modem as a USB storage device. As a result, you may not be able to access the internet through the modem. To resolve this issue, you need to change the device's identification mode using the usb-modeswitch package. If your system already has internet access, you can easily install this package.

First, you should check whether usb-modeswitch is already installed on your system. To do this, open the Terminal and type the following command:
sudo usb_modeswitch
If the package is installed, you will see output confirming its presence on your system.


If usb-modeswitch is not installed on your system, you will encounter the following error message:

 bash: usb_modeswitch: command not found

To install usb-modeswitch, you can use the following commands:

 sudo apt-get update
sudo apt-get install usb-modeswitch

If your system currently lacks internet access, you can download the usb-modeswitch package from the links provided below.

 Ubuntu/Lubuntu/Kubuntu (ubuntu base)

 For RPM Base Systems

 Install it through your package manager 
eg - Debian 
dpkg -i usb_modeswitch.deb

Let's discuss how to connect Huawei USB modems. First, you should check if the kernel has already detected the USB modem. To do this, type the following command:

bash
Type lsusb .

If your output includes a 3G/LTE/UMTS/GSM Modem/Network card, then your modem has already been detected.

Even though the modem has been detected, you may still encounter issues connecting via the network manager. If this is the case, you can watch the following YouTube video for assistance:

The first four hexadecimal digits represent the Vendor ID, and the last four hexadecimal digits represent the Device ID.

For Huawei modems, you can use the following command:

lsusb
The 4 first hexadecimal digits are the Vendor ID.
The 4 last hexadecimal digits are the Device ID.

Huawei{

 sudo usb_modeswitch -H -v vender -p product

 eg -

 sudo usb_modeswitch -H -v 12d1 -p 1506

 }

If your modem has been detected but you still cannot connect via the network manager, please refer to the YouTube video linked above.

Department for Persons Registration of Sri Lanka

Yesterday, I went to the Department for Persons Registration to get a new NIC after losing my old one. I arrived at 9:00 AM and had to stand in a long queue for about 30 minutes. They then gave me a number card and told me they would call me to the counter according to that number. They finally called me at 11:30 AM, and I paid the fee. When I handed over my file, I mentioned that there was a correction needed in my name. They assured me that it wouldn't be a problem and that they would enter my name as it appears on my birth certificate. After standing around for a long time, they finally announced my name at 3:30 PM. However, when I received my NIC, I noticed that my name had not been corrected. What they did was simply copy the details from my old NIC and paste them into the new card (CTRL+C, CTRL+V). Usually, if there is an error, it should be corrected through the Deputy Commissioner of the One Day Service. I was very exhausted, so I didn’t bother correcting it and quickly lef...

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 ...
