…interpretive, dynamic, state-changing, attribute value watching… and fun!
The C model compiler has received new features this summer. Here are some of the changes: Move to PyRSL version 2… way faster. keyed timers (now default) simulated time state save reflexive associative (loading) current state (changed before action body runs rather than after) poly to subtype (not supported so flagged as error) persistence of

In October, One Fact’s own Cortland Starrett will be teaching a 2-weeks long (all day each day) xtUML modeling course at Shinshu University in partnership with Takao Futagami and under the guidance of Professor Mizue Kayama. Look for the class syllabus coming soon.
…or Generalization and Specialization. In a modeled system, it is often important to categorize the entities in the system. Shown below a sedan and a sports car are both types of car each having a specialization. A convertible is a specialization of sports car.
Eclipse Oxygen You can breathe easier; BridgePoint is now running on Eclipse Oxygen. We skipped Neon, and it is too soon for Photon. Oxygen keeps the xtUML editor, Verifier and model compilers on a platform that is mature yet fresh. Download a nightly build.
LEGO robots are toys, fun toys. But they also are widely used in the engineering community for research and education. The platform is relatively sophisticated and quite powerful. The LEGO MindStorms EV3 programmable brick is built from a TI Sitara AM1808 (ARM926EJ-S core) running @300 MHz. There are 64MB of RAM, 16MB of onboard flash

Easy Chair Conference season is coming. MODELS 2018 is in Copenhagen in October. xtUML will be represented in the EXE and MDETools workshops. Of course, xtUML Days will be Monday and Tuesday. Most conferences these days use EasyChair to submit and evaluate papers and presentations. We are a fan; it is a great system. See

MC-3020 has a new feature called State Save. A mechanism to capture the present state of all state machine instances is provided through the State Save feature. Once triggered, the current state of each running instance state machine is written to a buffer. Outstanding events from the event queues are also written to the buffer.

xtUML Days 2018 is co-located with MODELS in Copenhagen, Denmark in October. MODELS is increasing its focus on Industrial Modeling while maintaining the academic and research strength of the conference. The graphic highlights the different industrial opportunities at MODELS this year.
We like the BeagleBone Black development board. It is small, fast and runs full Debian Linux. We jacked it in to our network, ssh’d to it and started development. gcc is on-board, so we can edit our source with vim and compile on-board. Anything missing is just an ‘apt install’ command away. BridgePoint xtUML models translated
