Enterprise all your Twisted applications with Ldaptor

2000px-Twisted_Logo_(software).svg

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

For a full review of what has changed, feel free to take a look at our live documentation over at ReadTheDocs: Ldaptor Documentation and the Changelog itself.

VideocoreIV Glamor on your Raspberry Pi

RaspberryPi Logo

Running an X (Xorg) server on your Raspberry Pi is frustrating. You can either use the fbdev or fbturbo driver which will give an un-accelerated 2D environment with swrast 3D (OpenGL) all beating your poor RPi’s CPU. Overclocking it will only help you so much which is a pity considering that there is another layer on the SoC that would be perfect for that but is now unused.

Enter the VideocoreIV (VC4) and Eric Anholt (formally of Intel, now of Broadcom), who are going to breath new life into the RPi. The idea is to offload the 2D rendering, via Glamor, to the VC4 with OpenGL calls. Since a OpenGL stack needs to exist, that means there will be a Direct Rendering Manager (DRM) Linux kernel module and Gallium/DRI module in Mesa.

This is happening now, here is the current status of support via the Piglit test-suite: skip 19102, fail 3866, pass 3146, crash 153, total 26267

Development on the Raspberry Pi

RaspberryPi Logo

Now that I’m a proud owner of a Raspberry Pi, I’ve being really stressing the little guy. There is only but so much a ARMv6 processor, on an microSD with only 512MiB of ram can do, which means that compiling on such a machine is going to take a really long time.

Take for example OpenMW, currently it takes about 4 minutes on a quad-core i7 to compile. You’re in for a treat on the Pi, it will take you at least a day, two days if you realize that half-way through the OOM Killer came through and killed your cc process. This is about the time you start wondering about various ways to improve the situation, such as a larger swap file or using zram.

At this point, I was wondering about other ways compiling binaries and packages for the Pi. There was cross-compiling, but then I would have to set up a full toolchain and recompile all the packages from scratch. That will have to be for another post though as it is another world. Another option is to try virtualizing the Pi and apparently QEMU gets us pretty darn close.

WildMIDI 0.3.7 has been released

WildMIDI

We’re still quite busy with developing 0.4 and thought it was best to backport our fixes into the 0.3 branch. As a result we ended up having an additional 2 releases in the 0.3 branch!

What’s new in this release

We’ve added DOS support in the form of SoundBlaster 16 playback in the player. The other big surprise is MIDI type-2 support, which came as a by-product of fully supporting XMI files like those from The Legend of Kyrandia. The rest of the changes are further enhancements to our build system and bug-fixes.

WildMIDI 0.3.5 has been released

WildMIDI

We have a brand new release on our 0.3 branch! The intent here is to be the bridge between the older 0.2 series and our feature rich 0.4 that is currently under development.

Downloads
Source and binaries can be found on our github release page:
https://github.com/Mindwerks/wildmidi/releases

New and Old Developers

After a few months of development, we’ve really brought WildMIDI a long way. We are rejoined by Chris Ison (Wildcode) who had taken a small break away from development. Another developer has also joined us from uHexen2, Ozkan Sezer, who has contributed quite a lot to the project. Welcome guys! If you want to help out, just create a github account, fork us and send pull requests. Other forms of help are also appreciated, tracking down bugs and new platforms for us to support.
