Running Webex on Ubuntu
Webex running on Ubuntu and other non-Windows platforms is literally a click away, in this case the CMR (Collaboration Meeting Room).
Webex is a fact of life for many people and for many Linux (BSD and other non-Windows) users, it has been a thorn in the side with people going so far as to set up virtual machines just to run Cisco’s collaboration software. While Webex is written in Java, it isn’t so simple to get running everywhere and apparently not all features are available for non-Windows users.
Most likely you are running up against the following message after logging into *.webex.com
Your browser,browser version, or operating system is currently unsupported
This requires the intervention of whoever is administrating the *.webex.com account and they can modify it in the following way.
Using Qemu and Chroot to replace your cross-compile toolchain
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.
Wireless BCM4312 with the 3.10, 3.11, 3.12 and 3.13 kernels
The hybrid driver from Broadcom was updated again in September (2013) with all the previous patches and a few other fixes as well. This brings them up to support linux kernel 3.9, which is very much welcome.
Sadly it breaks again with >= 3.10 with many warnings and errors which isn’t good considering that Ubuntu (13.10) Saucy Salamander is about to be released.
We do have a patch for you though that gets us working again up to the 3.11 kernel.
Chipsets supported by “Broadcom’s IEEE 802.11a/b/g/n hybrid Linux® device driver” are: BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM43224, BCM43225, BCM43227 and BCM43228.
Worldsynth 0.11.0 released
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.
