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 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.

We currently support the processing of:

the United States' Global Positioning System (GPS);
the Russian GLONASS system (GLONASS);
the European Union's Galileo system (Galileo);
the Chinese Navigation Satellite System (BeiDou);
the Japanese QZSS develop system (QZSS).
We are actively developing Ginan to have the following capabilities and features:

Precise Orbit & Clock determination of GNSS satellites (GNSS POD);
Precise Point Positioning (PPP) of GNSS stations in network and individual mode;
Real-Time corrections for PPP users;
Analyse full, single and multi-frequency, multi-GNSS data;
Delivering atmospheric products such as ionosphere and troposphere models;
Servicing a wide range of users and receiver types;
Delivering outputs usable and accessible by non-experts;
Providing both a real-time and off-line processing capability;
Delivering both position and integrity information;
Routinely produce IGS final, rapid, ultra-rapid and real-time (RT) products;
Model Ocean Tide Loading (OTL) displacements.
The software consists of two main components: Network Parameter Estimation Algorithm (PEA) and Precise Orbit Determination (POD).

This project allows you to use various hardware security devices to operate GPG and SSH. Instead of keeping your key on your computer and decrypting it with a passphrase when you want to use it, the key is generated and stored on the device and never reaches your computer. Read more about the design on https://github.com/romanz/trezor-agent/blob/master/doc/DESIGN.md

Currently TREZOR One, TREZOR Model T, Keepkey, Ledger Nano S, and OnlyKey are supported.

Scalable from 8-bit to 32-bit microcontroller environments, the primary governing standards in NuttX are Posix and ANSI standards. Additional standard APIs from Unix and other common RTOS’s (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
