 Steiner
Tree Approximation via Iterative Randomized Rounding.
.
Invited submission to the Journal
of the ACM. Journal version of the STOC'10 paper.
Slides (short). Slides (long).  Bin Packing via Discrepancy of
Permutations. .
Invited submission to TALG SODA'11 special issue.
Remark: This is the journal version of the SODA'11 paper. Since the conjecture of Beck has been disproven few months after SODA'11 by Newman and Nikolov, I recommend to read this journal version instead of the original SODA paper.  A simpler proof
for O(congestion + dilation) packet routing.
