The Digital Millennium Copyright Act has a lot of issues, and one of them is the almost instantaneous way in which content can be removed from the web if a copyright holder thinks it's in violation - it's a pretty classic example of "guilty until proven innocent." That double-edged sword is swinging back at Qualcomm today: the company issued an apology to developers after forcing popular code repository GitHub to remove over 100 repos for violation of copyright.
Shortly after Facebook announced the Chat Heads feature of Facebook Home, the folks behind ParanoidAndroid started expanding that idea into a new take on multitasking. HALO was the result, but it was exclusive to ParanoidAndroid. I say was, because HALO has just been open sourced.
The code has been added to a Github for other ROM developers and curious users to play around with. HALO is still in beta, but the feature set has come along quite well in recent weeks.
A French image processing company by the name of DxO Labs has filed a DMCA takedown request targeting 12 GitHub repositories containing device-specific code for ROMs, most of them maintained by CyanogenMod team members. The notice is vague, only citing:
 I have a good faith belief that the file downloads identified below (by URL) are unlawful under these copyright laws because among other things, the files circumvent effective access controls and/or copyright protection measures;
Content Type: "Custom Firmware" files
Violation(s): Trafficking a device that circumvents effective access controls and/or trafficking a device that circumvents effective copyright protection measures.
Multi-user support is one of the few remaining things a desktop OS can do that Android can't. The "coffee table tablet" use case would greatly benefit from a multi-user setup, as would an enterprise user who wants to keep work and home separate. It's been a top 20 item on the Android bug tracker since the debut of Honeycomb, so there is certainly demand for it.
As we've seen from my previous experiments in sticking my nose where it doesn't belong, Google likes to leave breadcrumbs in shipping products for the astute observer to find, and the multi-user situation is no different.
One of the key aspects of Android is its open-source nature, and one of the biggest players in the open-source community is GitHub. What better way to tie that all together than for GitHub to release an Android app? Probably none.
Clearly GitHub subscribes to a similar school of thought, as it has just released a swish-looking application to the Play store, offering a bunch of nifty features like issue tracking, following your friends' projects, and discussing code with the community.
