WorldEngine 0.19 has been released! In case you’re wondering, WorldEngine is the combination of two projects: Lands and WorldSynth. The biggest gain in the merge is that we’re now two developers on the same wavelength and we’ve added plate tectonic simulations! As things have become more serious and complicated, we’ve had to write tests suites to cover our bases. We’re currently about 86% code coverage and the tests guarantee reproducibility which aids us in finding regressions. We’ve got many contributions, so having these in place are crucial for project stability.
What’s new in WorldEngine 0.19:
- Speed of generation increased by almost a factor of 3 (due to update to Platec and making heavy use of numpy).
- World-generation is now deterministic, i.e. generation is 100% reproducible.
- Added support for exporting heightmaps using libgdal (see http://www.gdal.org/formats_list.html for possible formats).
- Added the ability to modify temperature and humidity ranges as well as the temperature/precipitation curve.
- Added the ability to generate scatter plots showing temperature and humidity of all terrestrial cells.
- Added small variations to the temperature-map based on basic orbital parameters.
- Added a satellite-like view of the world.
- Added support to save/load worlds in/from HDF5-format.
Murphey had an adage: “Anything that can go wrong, will go wrong.” The best we can do is attempt to anticipate any problems that might come up and keep ‘the machine’ running. From an end-user perspective that means being responsive, even with errors. If there is a network error, we want to know as soon as possible with the guarantee that state of ‘the machine’ was not effected by the error.
We now have per-call deadline and timeouts!
We’re proud to announce the release of 0.6 of TxMongo, which brings SSL support using Twisted’s SSL context factory, “find with cursor” support just like PyMongo, bug fixes and updated unit tests! TxMongo is an asynchronous MongoDB client written for Twisted in Python.
The biggest change is that TxMongo is now sponsored by Amplidata. Through them we were able to get development, bug fixes and Twisted first-party sponsorship online. We now have continuous integration (CI) with a wide matrix of support for py26/py27/pypy using Twisted 12.1 to 14.0 (and trunk). We also now have 78% code coverage with unit testing as a result!
This is also the very last release in the 0.x series before we step over to the “year.release” model used by Twisted, it will also eventually find its way into Twisted’s github organization as a first class library.
You can download TxMongo 0.6.0 and other releases here: TxMongo Github Releases
We’re proud to announce the release of 14.0.0 of Ldaptor, now a first party Twisted project! Ldaptor is an asynchronous LDAP (Lightweight Directory Access Protocol) client and server implementation written for Twisted in Python.
The biggest change is that Ldaptor is now sponsored by Amplidata. Through them we were able to get development, bug fixes and Twisted first-party sponsorship back online. We now have continuous integration (CI) with a wide matrix of support for py26/py27/pypy using Twisted 12.1 to 14.0 (and trunk). We also have about 75% code coverage with unit testing!
You can download 14.0.0 and other releases here: Ldaptor Github Releases
Worldsynth version 0.11.0 is released and can be found on github.
In this release we’ve added an additional algorithm for heightmap generation based on Ken Perlin‘s work in noise generation. We decoupled the sea-level to be configurable based on percentage, which in addition to masks we can now create islands. You can also save your world and open it up later since we use pytables to store our settings, metadata and our data in an open hdf5 format. You can also export your heightmap in 16-bit PNG greyscale or even import from a wide array of images formats as a heightmap. Importing from an image creates a 16-bit precision greyscale heightmap. In addition to this, one commenter ask about Python3 support, well now you have it.
