RLog is a software that provides a flexible message logging facility for C++ programs and libraries.
It is subscription based, meaning you can subscribe to messages of your choice in an number of ways: by hierarchical channel name (e.g. "debug", "debug/ special", "error", etc.), or filename, component name, etc.
Log messages are individually enabled. It is meant to be fast enough to leave in production code - even where it may be called many times, as both the GCC and Intel compilers reduce the logging overhead a few clock cycles if they are dormant (with no subscribers).
Other add-on components can extend subscriptions to external programs, allowing you to enable and collect debugging messages remotely.
Usage:
In order to begin using RLog in your code, you should do the following:
define RLOG_COMPONENT in your build environment. Eg: librlog is built with -DRLOG_COMPONENT="rlog".
You should use a unique name for your program or library (do not use "rlog"). If your program is made up of separate components, then you can define RLOG_COMPONENT as a different name for each component.
(optional) add a call to RLogInit() in your main program startup code. This is not a requirement, however not including it may reduce functionality of external rlog modules.
link with librlog
add subscribers (rlog::StdioNode , rlog::SyslogNode , or your own) to catch any messages you are interested in.
Enhancements:
- Features were added to the StdioNode logger and the build scripts were updated.

PAR::Tutorial is a cross-platform Packaging and Deployment with PAR.

SYNOPSIS

This is a tutorial on PAR, first appeared at the 7th Perl Conference. The HTML version of this tutorial is available online as http://aut.dyndns.org/par-tutorial/.

On Deploying Perl Applications

% sshnuke.pl 10.2.2.2 -rootpw="Z1ON0101"
Perl v5.6.1 required--this is only v5.6.0, stopped at sshnuke.pl line 1.
BEGIN failed--compilation aborted at sshnuke.pl line 1.

Q: "Help! I cant run your program!"
A1: Install Perl & perl -MCPAN -einstall(...)
How do we know which modules are needed?
New versions of CPAN modules may break sshnuke.pl
A2: Install Perl & tar zxf my_perllib.tgz
Possibly overwriting existing modules; not cross-platform at all
A3: Use the executable generated by perlcc sshnuke.pl
Impossible to debug; perlcc usually does not work anyway

2E Programming Language (two es, as in ee, or expression evaluator) is a simple algebraic syntax language. It natively supports expressions (composed of operators and operands), and function definitions, and basically nothing else. Therefore, it can be fairly straight-forward to learn (assuming you are already familiar with general programming constructs).
The language itself is refered to as 2e, however the interpreter is called ee.
An operand can be a literal, such as a numeric value (integer or floating point), a quoted string, a single-quoted character, a variable or a function call. Operators consist of the standard algebraic operators (i.e., *, /, +, -), assignment ("="), logical operators (, =, ==), sub-expression join operator (";"), and a conditional operator pair ("? :") like in C. Also added, is an iterative conditional pair ("?? :").
Heres a couple of examples:
ee -p 2 + 3 * 7
23
In this case, when called with the "-p" flag, the next parameter is evaluated and the final result printed. The "-c" flag does the same thing, but doesnt print the final result (use this when the expression already contains output statements).
ee -c x = 7; y = 11; z = (x * y); print(z; "n")
77
The ";" operator isnt really a statement terminator, it is actually a join operator. It evaluates the left and right expressions, and returns the result of the right hand side. It has the lowest order of precedence, so in general use you can treat it like a statement terminator (however it can be used in the middle of a larger expression, such as within parentheses grouping). It also does double-duty as a function parameter delimeter, such as the print function in the previous example.
The way that the "?" (conditoinal) operator works is as follows:
result = expr_test ? expr_true : expr_false
If expr_test is true (non-zero), then expr_true is evaluated and returned, otherwise expr_false is evaluated and returned. This is just like the inline conditional in C.
Also supported, is the iterative conditional:
result = expr_test ?? expr_true : expr_false
This will evaluate expr_test repeatedly, and as long as it is true, will evaluate expr_true. Once expr_test becomes false, then the final expr_true value is returned as the result of the whole expression. However, if expr_test never was true to begin with, then and only then is expr_false evaluated and returned. Therefore, expr_false can be used for some error handling, for example.
If an operator of lower precedence than ? or ?? is encounterd such as the ";" (join) operator, then a default false target will automatically be assumed. Therefore,
result = expr_test ? expr_true : 0; ...
result = expr_test ? expr_true; ...
are both the same. Heres a more extensive example, highlighting a few more of the operands avaliable. This example also calls the interpreter using the unix "#!" syntax, same as what is used for other scripting languages.
#!/usr/local/bin/ee
# This is a comment
i = 0;
x = 0;
i < 10 ?? ( # Read this as "while i is less than 10"
j = 0;
j < 5 ?? ( # while j < 5
array[i][j] = x; # here we are assigning a value to a 2-dimentional array
j++;
x++
);
i++
)
This example uses the iterative conditional operator to initialize an array. Notice the missing ";" after x++ and i++. this is because they are not followed by an operand (instead, in this case are followed by a closing parenthese). The ";" operator is a binary operator, no different than +, -, *, /, etc. Therefore, it is only used between to operands or two sub-expressions.
Enhancements:
- This release adds a bunch of functions to round out the string handling capabilities of 2e.
- Also added are "anonymous" functions, bitwise operators, and a few code cleanups.

DirectFB is a thin library that provides developers with hardware graphics acceleration, input device handling and abstraction, integrated windowing system with support for translucent windows and multiple display layers on top of the Linux Framebuffer Device.
DirectFB project is a complete hardware abstraction layer with software fallbacks for every graphics operation that is not supported by the underlying hardware. DirectFB adds graphical power to embedded systems and sets a new standard for graphics under Linux.
Main features:
- Rectangle filling/drawing
- Triangle filling/drawing
- Line drawing
- Flat shaded triangles
- Simple blitting
- Stretched blitting
- Textured triangles (perspective correct)
- Blending with an alphachannel (per pixel alpha)
- Blending with an alpha factor (alpha modulation)
- Nine source and destination blend functions
- Porter/Duff rules are supported
- Premultiplied alpha supported
- Colorized blitting (color modulation)
- Source color keying
- Destination color keying
Enhancements:
The time has come
Let it all begin,
Start the future,
Head forward and
Make it happen
This is for you!
