  • SC4: Secure Communications in a Very Small Code Base
    SC4 is a secure communications system specifically designed for (relatively) easy auditability by way of a ruthless commitment to simplicity. SC4 provides the functional equivalent of PGP from the end-user's point of view, but implements it in two order of magnitude less code. The cryptographic core of SC4 is Daniel J. Bernstein's TweetNaCl library (<800 LOC). On top of this we have a variety of UI implementations ranging from 1000 to 5000 LOC. One of these has completed a formal audit to date.

  • Google Calendar Command Line Interface
    gcalcli is a Python application that allows you to access your Google Calendar(s) from a command line. It's easy to get your agenda, search for events, add new events, delete events, edit events, see recently updated events, and even import those annoying ICS/vCal invites from Microsoft Exchange and/or other sources. Additionally, gcalcli can be used as a reminder service and execute any application you want when an event is coming up.

    gcalcli uses the Google Calendar API version 3.

  • gLAB Tool Suite — Research group of Astronomy and GEomatics. gAGE — UPC. Universitat Politècnica de Catalunya
    gLAB is a software tool suite developed under an European Space Agency (ESA) Contract by the research group of Astronomy and Geomatics (gAGE) from the Universitat Politecnica de Catalunya (UPC), is an interactive educational multipurpose package to process and analyse GNSS data.

    gLAB performs precise modeling of GNSS observables (pseudorange and carrier phase) at the centimetre level, allowing both standalone GPS positioning and PPP. Every single error contributor may be assessed independently, which, in turn, provides a major educational benefit. gLAB is adapted to a variety of standard formats like RINEX-3.00, SP3, ANTEX and SINEX files, among others. Moreover, functionality is also included for GPS, Galileo and GLONASS, allowing performing some data analysis with real multi-constellation data.

    The gLAB software tool is quite flexible, able to run under Linux, Windows, and Mac operating systems and is provided free of charge by ESA Education Office to universities and GNSS professionals.

  • The Pins They Are A-Changin’
    Some fairly major (and frankly rather overdue) changes are coming in the way that users access the GPIO pins on the Raspberry Pi. The shift will (hopefully) be fairly gradual and, for users of certain libraries, entirely invisible. However, for others they may be quite disruptive. As forewarned is forearmed, hopefully this little article may be of some use to those affected!
