Raymond As editor of the Jargon File and author of a few other well-known documents of similar nature, I often get email requests from enthusiastic network newbies asking (in effect) "how can I learn to be a wizardly hacker? ". Back in 1996 I noticed that there didn't seem to be any other FAQs or web documents that addressed this vital question, so I started this one. A lot of hackers now consider it definitive, and I suppose that means it is. Still, I don't claim to be the exclusive authority on this topic; if you don't like what you read here, write your own.

The GNU C Reference Manual This is the GNU C reference manual.
Preface This is a reference manual for the C programming language as implemented by the GNU Compiler Collection (GCC). Specifically, this manual aims to document: The 1989 ANSI C standard, commonly known as “C89” The 1999 ISO C standard, commonly known as “C99”, to the extent that C99 is implemented by GCC The current state of GNU extensions to standard C This manual describes C89 as its baseline. By default, GCC will compile code as C89 plus GNU-specific extensions. Algorithm.
Flow chart of an algorithm (Euclid's algorithm) for calculating the greatest common divisor (g.c.d.) of two numbers a and b in locations named A and B.
The algorithm proceeds by successive subtractions in two loops: IF the test B ≥ A yields "yes" (or true) (more accurately the numberb in location B is greater than or equal to the numbera in location A) THEN, the algorithm specifies B ← B − A (meaning the number b − a replaces the old b). Similarly, IF A > B, THEN A ← A − B. The process terminates when (the contents of) B is 0, yielding the g.c.d. in A. (Algorithm derived from Scott 2009:13; symbols and drawing style from Tausworthe 1977).
In mathematics and computer science, an algorithm ( i/ˈælɡərɪðəm/ AL-gə-ri-dhəm) is a step-by-step procedure for calculations. Informal definition[edit] Operators in C and C++ When not overloaded, for the operators &&, ||, and , (the comma operator), there is a sequence point after the evaluation of the first operand.
C++ also contains the type conversion operators const_cast, static_cast, dynamic_cast, and reinterpret_cast. The formatting of these operators means that their precedence level is unimportant. Table[edit] For the purposes of this table, a, b, and c represent valid values (literals, values from variables, or return value), object names, or lvalues, as appropriate. R, S and T stand for any type(s), and K for a class type or enumerated type. "Can overload" means that the operator can be overloaded in C++.

As we get closer to the New Year, the ritual of making resolutions begins and we all flock to the usual patterns: we want to eat healthier, work out more, get promoted, or spend more time with our kids and family. These are with no doubt worthwhile goals, but I’d like to pose an important challenge for founders: Make learning and development your key resolution in 2013.
If you’re a startup, you are by definition competing with the smartest people in the world – either large companies with more resources than yours or fellow entrepreneurs who are hoping to disrupt large companies. Your knowledge can make the difference between failure and success. Learning a new skill can also increase the chance of serendipity, the “magic” moment when seemingly unrelated concepts form an orignal thought in your head.
