Pharrell Williams, Robin Thicke, and T.I. in the video for "Blurred Lines."

The copyright dispute between “Blurred Lines” song creators Pharrell Williams and Robin Thicke, and the family of Marvin Gaye, will continue on to a higher court.

Earlier this year, Gaye’s family said in court that Williams and Thicke stole critical elements from Gaye's 1977 song “Got To Give It Up” for their 2013 hit “Blurred Lines." A jury agreed with Gaye’s family and awarded them $7.4 million, which was later reduced to $5.3 million. Now, Williams and Thicke are looking to appeal (PDF) that decision in the 9th Circuit Court of Appeals.

The case was unusual because in a pre-trial hearing, the judge ruled that the applicable 1909 copyright law only covered sheet music, not the song’s actual sound. The judge later reversed his decision, ordering Williams and Thicke’s lawyers to produce an audio recording of “Got To Give It Up” that only included a bass line and keyboard chords underneath some vocals from Gaye. This was the only version of “Got To Give It Up” that the jury was permitted to hear to compare with “Blurred Lines."

Microsoft promised to bring its Cortana digital personal assistant to iOS and Android in May this year, and public beta for Android came out in July, with a private iOS beta following a few months later. Now both versions have been released, with Cortana available in the App Store and in the Google Play Store, at least for US users.

Cortana's appointment and flight tracking.

We looked at the Android preview when it first came out. The version shipping today isn't hugely different from what we saw in July. The Cortana app looks essentially the same whether on Windows 10, Windows 10 Mobile, iOS, and Android; search box at the bottom, hamburger menu on the top left, and information cards. Those cards can show appointments, track packages, give you weather information or the latest sports scores, and so on. Cortana requires a Microsoft Account to use, and will sync your various interests and settings between all Cortana-enabled devices.

There are some differences in capabilities due to the API availability of the respective platforms. Neither iOS nor Android supports opening apps or changing settings from within Cortana. On Android, "Hey Cortana" voice activation is supported on the Android home screen, but not system-wide. On iOS there's no hands-free voice activation at all. Missed call notifications are similarly Android- and Windows 10 Mobile-specific: miss a call on your Cortana phone, and your Cortana Windows 10 PC will tell you. You can write an SMS to reply to the caller on your PC, and through the power of Internet syncing, the SMS will get sent to the caller from your phone.

Leaders in both major political parties have increasingly been calling on tech companies to give law enforcement encryption backdoors in the wake of recent terror attacks in Paris and California.

Today, FBI director James Comey has suggested that Silicon Valley isn't faced with a serious technical problem, but rather a "business model problem," according to a report on his comments in The Intercept, based on C-SPAN video of the hearing.

On the face of it, Comey's statement would seem to back away from earlier suggestions that tech companies can and should find a way to allow access to data when law enforcement wanted it, but provide otherwise secure services. Critics have pointed out that any encryption backdoors that can be used by the "good guys" also lead to widespread insecurity, since they can also be exploited by not-so-good guys.

With less than a week to go before a trial, a class-action lawsuit over the copyright status of "Happy Birthday" has been resolved. Details of the settlement, including what kind of uses will be allowed going forward, are not clear.

A short order (PDF) filed yesterday by US Chief District Court Judge George King says that all parties have agreed to a settlement, and it vacates a trial which was scheduled to start on December 15. The key turning point came in September, when King ruled that Warner/Chappell's copyright transfer was invalid because there was no proof it was ever properly transferred from the Hill sisters, who claimed to have written the song.

The trial would have addressed damages issues. Also looming was a late copyright claim by Association for Childhood Education International (ACEI), a children's' charity affiliated with the Hill sisters. ACEI came forward in November to say that if Warner/Chappell didn't own the song, it did. The settlement revealed yesterday resolves all claims by the plaintiffs, Warner/Chappell, and ACEI.

Senator Ted Cruz opens the hearing.

While the eyes of the world are on Paris, where nations are hammering out an agreement to do something about the reality of climate change, the Senate Subcommittee on Space, Science, and Competitiveness once again held a hearing on Tuesday to debate whether climate change is for real. Subcommittee Chairman Ted Cruz (R-Tex.), who is running for his party’s presidential nomination, convened the hearing titled “Data or dogma? Promoting open inquiry in the debate over the magnitude of human impact on Earth’s climate.”

Senator Cruz brought in four witnesses to testify, mostly chosen from the usual suspects that have participated in similar hearings in the past. There were two of the very small handful of climate scientists who express doubts about human responsibility for climate change—Georgia Tech professor and blogger Judith Curry and John Christy from the University of Alabama in Huntsville. William Happer, a retired Princeton physicist and chairman of the George C. Marshall Institute, a conservative think-tank, was also invited to speak. The fourth person brought in to talk climate science was conservative radio host and columnist Mark Steyn. (The last two were keynote speakers at this year’s Heartland Institute conference for climate “skeptics.”)

Senator Cruz opened the hearing with some ironic remarks. “This is a hearing on the science behind the claims of global warming. Now, this is the Science Subcommittee of the Senate Commerce Committee, and we’re hearing from distinguished scientists, sharing their views, their interpretations, their analysis of the data and the evidence. Now, I am the son of two mathematicians—two computer programmers and scientists—and I believe that public policy should follow the actual science, and the actual data and evidence, and not political and partisan claims that run contrary to the science and data and evidence.”
