A gut feeling review of 2012.

In 2012, we saw some trends:

• an acceleration of work around AMP solvers from sparse recovery into matrix factorization.
• the move towards more complex signal structures (we are moving beyond simply cardinality and power laws and it's a about time) 
• personally a somewhat better understanding of the analysis based approach
• a continuing slew of good solvers (BSBL, any of the AMP solvers)
• more implementation in C++/Python for reconstruction solvers
• The actual use of several places where people exchange views (LinkedIn also here, Google+ and Reddit).
• a few low level interesting hardware development, ghost imaging being one of them but also the potential replacement of the Anger logic, FREAK
• a few new results that render TV-minimization and NMF a more stable theoretical grounding
• a few promising approach such the QTT tensor factorization, manifold signal processing, Protein-DNA interaction.
• a surge in phase retrieval, blind deconvolution approaches
• a surge of code implementations made available by the researchers themselves (36 in the last three months), two or three are on Github. Our field is becoming a trailblazer when it comes to reproducible research.  
• the birth of the RandNLA movement
• some continuing thoughts on post publication peer review process
• a series of compelling videos from GenomeTV
• a series of themes: Predicting the future, accidental cameras, Sunday Morning Insights, some Monthly Reviews
• Curiosity landing on Mars

Finally, with Cable we had fun with the CAI series and expect to continue it into 2013. Like the pirates sailing from one island of knowledge to the other, forward we go. Happy New Year 2013 to y'all.
