best methods for rapid increase in concentration

[electroBeam]

What are the best meditation methods for honing in on your concentration abilities - so that you can meditate with lazer focus, great intensity, and for long periods of time?

Is this method able to enhance your ability beyond meditation? Such as increasing the concentration ability to do mathematical and computer science/programming work?

I would think a vipassana course would be like 'boot camp'. intense but effective. I have never done one tho so I can't say any more.  I belive there are a few vipassana style guided meditations on youtube which would be good to do for a few months before attending the course. sorta like doing some pushup practice before going to a bootcamp will get you more prepared for the real work to come.
