  • Combined with Impala, Kudu is (among other things) an attempt to build a no-apologies analytic DBMS (DataBase Management System) into Hadoop.
  • The analytic RDBMS vendors are beatable. Teradata has a great track record of keeping its product state-of-the-art, but it likes high prices. Most other strong analytic RDBMS products were sold to (or originated by) behemoth companies that seem confused about how to proceed.
  • Predictive models now often get rescored on every click. Sometimes, they even get retrained at short intervals.

  • NGINX is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. NGINX is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption

  • Splice Machine 


  • The standard CIGAR description of pairwise alignment defines three operations: ‘M’ for match/mismatch, ‘I’ for insertion compared with the reference and ‘D’ for deletion. The extended CIGAR proposed in SAM added four more operations: ‘N’ for skipped bases on the reference, ‘S’ for soft clipping, ‘H’ for hard clipping and ‘P’ for padding. These support splicing, clipping, multi-part and padded alignments. Figure 1 shows examples of CIGAR strings for different types of alignments.

  • Time to Event
    The solution has a unique ability to track and analyze time-related events such as time in range and time to survival. When combined with event collections, cohorts can be studied over time.
  • Plugs Easily Into Any IT Environment
    Looking Glass® Clinical Analytics is built on an open architecture, exposing Web Services, component-based, and designed for integration with legacy systems and environments.

  • Lymphoma


    1. Narrow definition and diagnostic, radiation, chemotherapy procedure, or chemotheraputic drugs


    ICD-9 (200*, 201*, 202*)
      ((lymph node biopsy, bone marrow biopsy/aspiration,
      laparascopic staging, path report before radiation/chemo,
      PET scan) 30d before


    ((radiation, chemotherapy procedure) or
      (chemotherapeutic drugs) 30d after)

  • IMEDS is necessary to build on the work Mini-Sentinel and OMOP have completed over the last few years to advance the development of methods for the use and analysis of electronic healthcare data for safety evaluations.
