On Jeff Dean:http://research.google.com/people/jeff/, simply put, this is one of the sources of Google's awesome stuff. Because this person is really too cow, so there are several jokes about how he has a cow, directly laugh over, and share with you.
1. During His own Google interview, Jeff Dean is asked the implications if P=NP were true. He said, "P = 0 or N = 1." Then, before the interviewer had even finished laughing, Jeff examined Google's public certificate and wrote the private Key on the whiteboard.
When he was interviewed by Google, Jeff Dean was asked if P=NP meant anything. He said, "P=0 or N=1." Then, before all the interviewers had finished laughing, Jeff glanced at Google's public certificate and wrote the corresponding private key on the whiteboard.
2. Compilers don ' t warn Jeff Dean. Jeff Dean warns compilers.
The compiler never compiles a warning to Jeff, but Jeff warns the compiler
3. The rate for which Jeff Dean produces code jumped by a factor of all in late if he upgraded his keyboard to USB 2 .0.
After 2000 years, the speed of Jeff code suddenly soared 40 times times, because he upgraded his keyboard to USB 2.0
4. Jeff Dean builds his code before committing it, but only to the check for compiler and linker bugs.
Jeff will compile them again before committing the code, but only to check that the compiler and linker have bugs.
5. All pointers point to Jeff Dean.
All pointers are pointing to Jeff's
6. Gcc-o4 emails your code to Jeff Dean for a rewrite.
The-o4 optimization option for GCC is to rewrite your code message to Jeff.
7. The speed of light in a vacuum used to is about mph. Then Jeff Dean spent a weekend optimizing physics.
The speed of light in the vacuum was nearly 35 miles per hour, and Jeff spent a weekend tuning the physics a little bit.
8. Jeff Dean was born on December to 1969 at 11:48 PM. It took him twelve minutes to implement his first time counter.
Jeff was born at 11:48 P.M. on December 31, 1969 and then spent a full 12 minutes implementing his first timer. (Background: A timer value in a computer is typically designed to be the number of seconds from January 1, 1970 0:0 0 seconds to current)
9. When Jeff Dean sends an Ethernet frame there is no collisions because the competing frames retreat back to into the BU Ffer memory on their source NIC.
When Jeff sends a packet to the Ethernet, there is never a conflict, because the package that is supposed to conflict with it silently withdraws the buffer
Unsatisfied with constant time, Jeff Dean created the world ' s first O (1/n) algorithm.
Jeff was not satisfied with the time complexity of the constant, so he created the first O (1/n) algorithm in the world. (That is, the less time it takes to solve problems as the size of the problem increases)
