Awhile back I wrote about how you can set up a cross-compile toolchain for compiling on x86_64 with the Raspberry Pi as a target. There is another, perhaps easier way to do the same thing by using Qemu 2.0 as your backend.
By installing and enabling Qemu support, you can run code compiled for another architecture (that is supported by Qemu) on your native machine. You can then create a Chroot environment, perhaps similar to what you have on your Raspberry Pi, and run it as if it was natively.
WildMIDI 0.4 is released!
It has been two years in development and we’ve pushed WildMIDI 0.4 beyond just MIDI support, we’ve branched out into MIDI like files as well. We’ve worked together with other projects like GStreamer, OpenTESArena, XLEngine (DaggerXL), Thirdeye, ZDoom and more to ask what we can do to make their lives easier, as a result we now support rendering, streaming and playback of many older MIDI-like formats!
What’s new in this release
We’ve added support for KAR (MIDI with Karaoke) files, MIDI Type 2 and many MIDI-like formats such as HMI, HMP, MUS (Id) and XMI! We’ve also expanded our API in libwildmidi to support getting text/karaoke out of files, seeking songs in multi song MIDI Type 2, get errors instead of having a noisy library, setting conversion options, converting MIDI-like files into MIDI files and library now returns a buffer in the Endian format of the host.
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!
I recently upgraded to Ubuntu 15.10 (Wily Weerwolf) which automatically upgraded VirtualBox from 4.3 to 5.0 and broke compatibility with Vagrant 1.6 in the process. Thinking that Vagrant knows about this and they claim VBox 5.0 compatbility, I upgraded to 1.7 and came across the same error!
There is a workaround!
