  • When I think about what is possible with technical computing and the problems it can overcome in advancing the human race - I feel very very positive. I get the same feeling as when I think about Science - like the anything is possible. I get a similar feeling when I have a multilayer distributed application stopped by multiple debuggers at the exact point where a critical defect occurs - and realizing the solution is on the screen (or multiple screens - if you know me personally). It is hard to describe what exactly it is that is so appealing about my work - it may be the discovery of patterns and how to solve insurmountable problems.

It may be the feeling that nothing is beyond reach with the right amount of judicious technical discovery.

  • Everybody would like to optimized computations in their spare time - but using all available capacity of your servers is not an easy thing to do. Don't let let your multicore processor sit idle or use a small percentage of it's potential - use threads and push your processor to it's limit of parallel computation and use of electrical resources. Pass this very interesting graphic to all your Java, C++, C, Assembly and even Smalltalk friends. Don't worry about locking, deadlock, thread contention, thread scheduling, finished threads waiting on slower threads, data corruption, queuing, synchronization, concurrency issues, data parallel work distribution/merging, heat dissipation, and electicity usage - as everything can be solved.
