  • Linux Foundation Collaboration Summit - Austin, Texas - April 8th to 10th, 2008 -

    Unlike a lot of the events that I discuss in my Blog, the Linux Foundation Collaboration Summit is a "by invitation only" event with a twist. Normally for "invitation only events", the potential attendee sits by the phone with their prom clothes on, waiting for the call that may or may not come. more>>

    After speaking at the Florida Linux Show on February 11th, I return ever-so-briefly to the New England area to re-pack my bags and head for Sao Paulo, Brazil to attend Campus Party (February 11th to 17th, 2008). more>>

    I am looking for people to modify Etherpad to distribute its Javascript code marked clearly as free software, adding free licenses marked for LibreJS to notice, and source pointers if necessary. See etherpad-lite.

    Please write to me if you do this job, so I can stop looking for someone.

  • health @ Savannah: GNU Health will be at the International Symposium on Open Collaboration, OpenSym 2016 -

    Dear all

    We're proud to announce that Luis Falcon will be an invited speaker at the OpenSym 2016, the 12th International Symposium on Open Collaboration, will take place in Berlin, Germany on August 17-19

    It's a honor to be part of this great event, that puts together researches and practitioners from around the world.

    Thank you very much to OpenSym for having the GNU Health project, and looking forward to meet with the GNU Health and other Free communities in Berlin !

    Following is the abstract of the presentation Luis Falcon will be giving. For more details please visit the OpenSym homepage.

    GNU Health is community-based, Free/Libre Health and Hospital Information System, deployed in many countries around the globe. It merges Social Medicine with state of the art advances in bioinformatics, providing a framework for integrative medicine, governments and Public Health institutions as well as research organizations. In this presentation we will talk about case studies in Public health, integration with other Free Software community projects such as OpenStreetMaps, and the upcoming GNU Health Federation model to interconnect large, heterogeneous health networks. We will present some of the upcoming features on GNU Health, including topics on interoperability and standards (HL7 FHIR) or MyGnuHealth, a mobile application for Personal Health. Finally, we will dedicate a section to the GNU Health functionality on bioinformatics, personalized medicine, clinical genetics, big data, and cooperation with the academia, research institutions and multi-lateral organizations.

  • pspp @ Savannah: PSPP 0.10.2 has been released -

    I'm very pleased to announce the release of a new version of GNU PSPP. PSPP is a program for statistical analysis of sampled data. It is a free replacement for the proprietary program SPSS.

    Changes from 0.10.1 to 0.10.2:

    • CROSSTABS implements a new COUNT subcommand to round case or cell weights.
    • Help will be opened as HTML in default browser if yelp is not available.
    • When plotting scatterplots with only one dataset (the simple case) the colour used for the dataset is now black. The previous default from the Tango palette was too faint to see easily.
    • The varible info dialog could previously only paste a single variable. Now it can paste multiple variables.
    • Bug fixes, including the following:
      • T-test with independent samples GUI crashed with string type variable as group variable.
      • The variable info dialog showed the previous selected variable superimposed with the currently selected one.
      • The GLM command did not properly deal with missing values. This has been fixed.
  • parallel @ Savannah: GNU Parallel 20160722 ('Brexit') released -

    GNU Parallel 20160722 ('Brexit') has been released. It is available for download at:

    Haiku of the month:

    Pipes are fast and good.
    Use them in your programs, too.
    Use GNU Parallel
    -- Ole Tange

    New in this release:

    • env_parallel is now ready for wider testing. It is still beta quality.
    • env_parallel is heavily modified for all shells and testing has been increased.
    • Selectively choosing what to export using --env now works for env_parallel (bash, csh, fish, ksh, pdksh, tcsh, zsh).
    • --round-robin now gives more work to a job that processes faster instead of same amount to all jobs.
    • --pipepart works on block devices on GNU/Linux.
    • Bug fixes and man page updates.

    GNU Parallel - For people who live life in the parallel lane.

    About GNU Parallel

    GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel.

    If you use xargs and tee today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU Parallel can even replace nested loops.

    GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs.

    You can find more about GNU Parallel at:

    You can install GNU Parallel in just 10 seconds with: (wget -O - || curl | bash

    Walk through the tutorial (man parallel_tutorial). Your commandline will love you for it.

    About GNU SQL

    GNU sql aims to give a simple, unified interface for accessing databases through all the different databases' command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries.

    The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.

    When using GNU SQL for a publication please cite:

    About GNU Niceload

    GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.
