To swith to 2G GSM network go to Settings/Wireless and Network/Mobile Networks and check the option ? Use only 2G Networks?.

If in your phone there is no such options try to dial the code *#*#4636#*#* and choose Phone Information, set GSM Only in Set preferred Network Type.

Good luck

To fix it I had to do the following:
1. Reinstall cups-pdf

sudo apt-get purge cups-pdf
sudo apt-get install cups-pdf

note: you have to purge cups-pdf, simple installation does not work.

2. Enable PDF printer

Right click on PDF printer -> Properties -> Policies -> check “Enabled”, Click “Apply”.

To fix the full-screen flash videos bug, you need to preload a library called libGL.so.1 when you start Firefox or Swiftfox. Here is how to do it:

All you have to do is go to Applications > Internet and right click Firefox, then select “Add to panel”. Then right click the newly create icon on your Gnome panel, edit it and in the “Command” field, in front of firefox %u put env LD_PRELOAD=/usr/lib/libGL.so.1

env LD_PRELOAD=/usr/lib/libGL.so.1 firefox %u

I never wanted to do the NVRAM complete reset because I was scared of losing the network MAC address as mentioned at some forums. Controlling the consumable level independently was much more interesting. Here is the step by step instruction:

Get to the standard “Diagnostic mode”:

1. Turn off printer.
2. Turn on printer, while holding the + and ? buttons.
3. The LCD Shows “OKI User”, Scroll to “Engine Diag Mode”, press “enter”.

The display shows “Diag Mode 01.02.02 S-Mode” as mention multiple times on this thread.

At this point you should wait for the initialization cycle to complete. I mean for all the motors and gears to have finished their noises and cycles ? otherwise you will end up with a LCD switching between two different info screens – not a big deal but still annoying.

Now we want to go in “regist mode” by:

1. Pressing the “Online”, “Cancel”, “Enter”, “-” and “Back” AT THE SAME TIME (not in any sequence ? at the same time). Yes! That is 5 buttons.
2. After within two seconds the LCD menu will show “READY”. If it doesn?t, release button and repress buttons again.
3. The buttons release sequence is important. So, read this before letting go your five fingers: Release the “Enter” button first and THEN the four others (for some firmware ?On Line? must be released first). LCD is still showing “READY”.
4. Press the “Online” and “Cancel” button at the same time BRIEFLY. Don?t wait before pressing them after the five fingers sequence otherwise you will miss your time slot.

You can always switch back from the “READY” to the “Diag Mode 01.02.02 S-Mode” menu by pressing the five buttons again.

Don?t laugh. I know it seems a lot of gymnastic. Well I guess they didn?t want the user to find that one easily.

Now you see “Eng Diag Level 2″

Press either the + or ? button until “CONSUMABLE COUNTER SET” is displayed, press the Enter button; you are now in the menu to set various consumables.

1. Press either the + or ? buttons to scroll through the various consumables, at the desired consumable (ie. “K-ID UNIT ?” for the Black Image Drum Unit, “C-Toner” for cyan toner, etc.), press the Enter button and the last digit of the count will start flashing.
2. Press the Cancel button to decrease the digit amount or press the On-line button to increase the digit amount; press the + or ? buttons to move along individual digits in the count. Note that it will not show the remaining but the usage (100% means it is empty).
3. Once the count is at the level you desire, press and hold the On-line, Cancel simultaneously until the numbers stop flashing; you have reset that consumable?s count to the number you specified. Note that you may end up with a different value then the one that was entered when saving. The printer engine is probably jumping to the nearest registered/acceptable value. If someone find a way to save the exact value, let us know.
4. Press the + or ? buttons to move to the next consumable and repeat at step 1
5. Once all consumable counts have been set to desired amounts that are below their end-of-life thresholds, you can use the Back, +, & – buttons to exit through the menus until “INITIALIZING” is displayed. Or turn printer off and on.

You’re finished! Now log in to the web interface with your browser and check to see the remaining life of your consumables.

Good luck.

Solution:
To solve the problem you need to change transfer mode (Control Panel >> System >> Hardware >> Device Manager IDE ATA/ATAPI controllers >> Primary or Secondary IDE Channel) back to DMA and reboot system. If this do not help or if your drive is still in PIO mode simply uninstall the channel and reboot. New hardware will be detected at system booting.

Using -E

When you specify the -E option, the compiler’s preprocessor expands your source module and writes the result to stdout. The preprocessed source contains #line directives, which the compiler uses to determine the source file and line number. For example, to preprocess two source files and write them to stdout, enter the following command:

• cc -E prog1.c prog2.c
• cc -E prog1.c prog2.c

Using -P

When you specify the -P option, the preprocessor expands your source module and directs the output to a .i file instead of stdout. Unlike the -E option, the output from -P does not include #line number directives. By default, the preprocessor creates the name of the output file using the prefix of the source file name with a .i extension. You can change this by using the -ofile option. For example, the following command creates two files named prog1.i and prog2.i, which you can use as input to another compilation:

• cc -P prog1.c prog2.c
• cc -P prog1.c prog2.c

!!! Caution !!!
When you use the -P option, any existing files with the same name and extension are overwritten.

Using -EP

Using the -EP option directs the preprocessor to not include #line directives in the output. -EP is equivalent to -E -P.

• IA-32 Systems: prompt>icc -EP prog1.c prog2.c
• Itanium?-based Systems: prompt>ecc -EP prog1.c prog2.c

Preserving Comments in Preprocessed Source Output

Use the -C option to preserve comments in your preprocessed source output. Comments following preprocessing directives, however, are not preserved.

Codeblocks is great application development platform for serial code, however when it came to Fluid Dynamic you realize that serial code, executed on a single processor is very slow, one of the solution is to use openMP especially for multicore processor, but to do some serious computation you need MPI (Message Passing Interface). Only then, you can run you code on hundreds of processors and your application really take-off.

Unfortunately Codeblocks (my favourite open source IDE) don’t support MPI programs. Hopefully, when this is an open source you can solve the problem by your self.

Here is my solution to run console MPI code from Codeblocks:

First you need to compile you mpi code and link it to mpi library:

Under Windows you need to configure:

In Project/Build options/Linker settings/Add mpi (under linux add m or lm)

In Search directories/Compiler/Add  C:\Program Files\MPICH2\include

In Search directories/Linker/Add  C:\Program Files\MPICH2\lib

In linux you need to compile the code using mpicc go to Setting/Compiler and Debugger… and create a copy of GNU GCC Compiler with new name GNU GCC Compiler MPI. Go to Toolchain executables and replace the gcc and g++ with mpicc and mpicxx. Next step is to change you MPI project building setting to use new compiler setting.

This should compile your parallel code.

Now we need to start the executable using mpiexec or mpirun.

Our console program on windows is executed by cb_console_runner.exe and there is no support for other host program if your project is console application (most of parallel programs are). A few simple modification in cb_console_runner.exe allow to define -mpi argument.

Argument this must be define in Codeblocks menu in Project -> Set programs’ arguments?

-mpi <path to mpiexec> -n <number of processes>

example:

-mpi C:/Progra~1/MPICH2/bin/mpiexec -n 8 

or (for linux)

- mpi /usr/bin/mpiexec -n 8 

You can download source code (main.cpp) and executable for windows and linux of cb_console_runner here:

http://blog.kubiak.co.uk/download/cb_console_runner.zip

Codeblocks project for hello world application in mpi is included (under linux make sure to create GNU GCC Compiler MPI with mpicc and mpicxx, for details see text above).

Thanks for reading and good luck with MPI, you will need it.
