Have you ever wondered how people manage to write such complicated make files when you struggle to write a simple one? There are several lengthy tutorials on make files available on the internet. But once in a while, I feel there must be a simple ppt or a pdf that has just the basic tutorials for me to refresh my memory if I have forgotten something. Here is the link for the ppt which is simple and easy to understand and may come as handy when you need it.

Interested in appearing for this year's JLPT and don't know what to do? RELAX!! Each metropolitan in India has its own Japanese committee which organizes JLPT exams every year. If you are a Bangalorean, then visit http://www.bnk-india.org/ to know the details of the office where examination forms will be distributed. The application forms will be on sale from 22nd July at the BNK office on Lalbagh Main Road from 11am to 3.30pm Monday - Saturday. The cost per form is Rs.100/- and payable by cash directly at the office, or payable by Demand Draft if you want it by post. The Demand Draft has to be in favour of "JLPT TEST ADMINISTRATIVE COMMITTEE", payable at Bangalore. Last date for submission of exam form is September 20th. After a month or so, you'll be getting your hall ticket which should be carried to the examination venue. Every year, BNK conducts JLPT during the first Sunday of December at Christ college (hosur road, dairy circle).
The exam fees are as below:

N1 & N2  --  Rs.1000/-

N3 -- Rs. 800/-

N4 -- Rs. 700/-

N5 -- Rs. 600/-

So if you haven't already started preparing for the exam, then pull up your socks and ganbatte kudasai!!

Compiler options are parameters you can specify to change the default behavior of the compiler. You can specify options from the command line

TYPES OF OPTIONS

There are two types of names for command line options, short names and long names.
Some options have both.
> short option name consists of one character, and it may have parameters. You specify it with a single dash, for example -e
> long option name consists of one or several words joined by underscores, and it may have parameters. You specify it with double dashes, for example
--char_is_signed.

Compiler options perform a wide variety of functions, such as setting compiler characteristics, describing the object code and compiler output to be produced, and performing some preprocessor functions. You can specify compiler options in one or more of three ways:
> on the command line
> in a configuration file (.cfg)
> in your source program

-c Suppress linking with ld(1) and produce a .o file
for each source file. A single object file can be
named explicitly using the -o option.

-C Prevent the C preprocessor from removing
comments.

-E Run the source file through the C preprocessor,
only. Sends the output to the standard output, or
to a file named with the -o option. Includes the
cpp line numbering information. (See also, the -P
option.)

-g Produce additional symbol table information for
dbx(1) and dbxtool(1). When this option is given,
the -O and -R options are suppressed.

-help Display helpful information about compiler.

-Ipathname Add pathname to the list of directories in which
to search for #include files with relative
filenames (not beginning with slash /). The
preprocessor first searches for #include files in
the directory containing sourcefile, then in
directories named with -I options (if any), and
finally, in /usr/include.

-llibrary Link with object library library (for ld(1)).
This option must follow the sourcefile arguments.

-Ldirectory Add directory to the list of directories contain-
ing object-library routines (for linking using
ld(1).

-M Run only the macro preprocessor on the named C
programs, requesting that it generate makefile
dependencies and send the result to the standard
output (see make(1) for details about makefiles
and dependencies).


-o outputfile
Name the output file outputfile. outputfile must
have the appropriate suffix for the type of file
to be produced by the compilation (see FILES,
below). outputfile cannot be the same as source-
file (the compiler will not overwrite the source
file).

-O[level] Optimize the object code. Ignored when either -g
or -a is used. -O with the level omitted is
equivalent to -O2. level is one of:

1 Do postpass assembly-level optimization
only.

2 Do global optimization prior to code
generation, including loop optimiza-
tions, common subexpression elimination,
copy propagation, and automatic register
allocation. -O2 does not optimize refer-
ences to or definitions of external or
indirect variables.


If the optimizer runs out of memory, it tries to
recover by retrying the current procedure at a
lower level of optimization and resumes subsequent
procedures at the original level.

-P Run the source file through the C preprocessor,
only. Puts the output in a file with a .i suffix.
Does not include cpp-type line number information
in the output

Very useful vi/vim editor cheat sheet for some quick commands ;)

We all use regular expressions in someway or the other. And whenever we do, we break a lot of sweat. So, here is a cheat sheet which I have been using and is very helpful.
