    LibreOffice 5.0 released
    The LibreOffice 5.0 release is out. "LibreOffice 5.0 sports a significantly improved user interface, with a
    better management of the screen space and a cleaner look. In addition,
    it offers better interoperability with office suites such as Microsoft
    Office and Apple iWork, thanks to new and improved filters to handle non
    standard formats.    " See this
    post from Michael Meeks     for a detailed description of the work that went
    into this release.

    [$] Fuzzing perf_events
    You might be surprised to learn that starting with Linux 2.6.31 (in 2009) it has been rather easy to crash the Linux kernel. This date marks the introduction of the perf_event subsystem. It is likely that perf_event is not any more prone to errors than any other large kernel subsystem, but it has the distinction of being subjected to intense testing from the perf_fuzzer tool, which methodically probes the interface for bugs.

    [$] "Big data" features coming in PostgreSQL 9.5
    PostgreSQL 9.5 Alpha 2 is due to be released on August 6. Not only
    does the new version support UPSERT, more JSON functionality, and other new
    features we looked at back in July, it also
    has some major enhancements for "big data" workloads. Among these are
    faster sorts, TABLESAMPLE, GROUPING SETS and
    CUBE, BRIN indexes, and Foreign Data Wrapper improvements. Taken
    together, these features strengthen arguments for using PostgreSQL for data
    warehouses, and enable users to continue using it with bigger databases.
