The solution to Linus' question on resolving undefined macros in the preprocessor to 0, as well as resolving defined macros to their values.
#include <stdio.h>
#define CONFIG_FOO 1
#define CONFIG_NOO 0
#define is_set(macro) is_set_(macro)
#define macrotest_1 ,
#define is_set_(value) is_set__(macrotest_##value)
#define is_set__(comma) is_set___(comma 1, 0)

Latency numbers every programmer should know

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

Hack Hadoop (1.0.3) to compile native libraries on OS X (so rmr does not fall back to non-native)
deps:
brew install md5sha1sum automake snappy hadoop
tweak OS X:
# export JAVA_HOME=$(/usr/libexec/java_home)
hack jvm:
# sudo mkdir -p ${JAVA_HOME}/lib/{i386,x86_64}/server
# sudo ln -s ${JAVA_HOME}/{../Libraries,lib/i386/server}/libjvm.dylib
# sudo ln -s ${JAVA_HOME}/{../Libraries,lib/x86_64/server}/libjvm.dylib
