You can’t stop a shaken beer can from fizzing over by tapping it, study finds

The best strategy for a shaken beer can is just to wait for the fizz to settle

Anyone who's fallen victim to the old "opening a shaken beer can" prank has likely heard that tapping the side of the can before opening it can keep the beer inside from fizzing over. It's a fun bit of folk wisdom, but apparently the science doesn't bear it out. Danish scientists from the University of Southern Denmark (USD) in Odense put the tapping strategy to the test, and found it really doesn't work. They summarized their findings in a recent paper posted to the physics arXiv.  

Beer is a surprisingly popular subfield of study for scientists. There was a 2011 Irish study on bubble nucleation in stout beers, for instance, and in 2016, scientists demonstrated how beer foam reduces sloshing of beer as it's poured into a glass, as well as enhancing the flavor. Back in 2013, Javier Rodríguez-Rodríguez, a physicist at Carlos III University of Madrid, and several colleagues presented experimental and computer simulation findings of why beer cans foam up so much after being shaken, at a meeting of the American Physical Society's Division of Fluid Dynamics. They concluded that the foaming over stemmed from a series of waves.

"Actually, the laws of physics that control the development of these beer mushroom clouds are the same as [those that drive] the development of the cloud in an atomic bomb," Rodriguez told NPR's The Salt at the time. "Obviously, there's no nuclear stuff in the beer. So the source of the explosion is very different, but the mushroom cloud that you see is very similar."

Start the new year right with terrifying trailer for A Quiet Place Part II

“The people who are left, they’re not the kind of people worth saving.”

Emily Blunt reprises her role as Evelyn Abbott in A Quiet Place: Part II.

Things haven't gotten much better for the beleaguered Abbott family, judging by the first official trailer for A Quiet Place: Part II, the sequel to director (and star) John Krasinski's 2018 breakout sci-fi/horror hit, A Quiet Place. It's an auspicious year for a sequel, given that the original film was set in 2020.

(Major spoilers for the 2018 film A Quiet Place below.)

A Quiet Place had a simple premise: in early 2020, sightless extraterrestrial creatures have wiped out most of the humans and animals on Earth. They hunt by sound, thanks to their hypersensitive hearing, and are difficult to kill because they sport a tough armored skin. (The creature's design was inspired by animal echolocation, prehistoric fish, and the infamous bog people: mummified bodies found in the bogs of northern Europe in particular. They look a bit like the Dementors from the Harry Potter films.)

European Commission Calls Out Canada’s Lacking Copyright Policy

The European Commission has published an updated list of foreign countries with problematic copyright policies. One of the highlighted countries is Canada which, according to the EU, has too broad copyright exceptions. In addition, the EU suggests that Canada should implement a takedown requirement to ensure that infringing content is swiftly removed by online services.

The Canadian Government is no stranger to having its copyright policies critiqued.

The US Trade Representative, for example, has repeatedly placed its northern neighbor on a “watch list” because it fails to properly deter piracy.

While Canada has made several changes to its copyright regime in recent years, many rightsholders are not satisfied. Through political pressure from foreign governments, they hope to urge the country to address what they see as problematic issues.

This doesn’t only take place through the US Government – the European Commission is chiming in as well. Repeating many of the points that were previously highlighted by the USTR, the Commission summarized its main complaints in a report on the protection and enforcement of intellectual property rights in
third countries

“The Canadian IPR system still features certain shortcomings. Despite recent positive developments, a number of issues remain to be addressed, in particular in copyright and related rights as well as in enforcement,” the European Commission writes.

One of the highlighted problems is Canada’s fair dealing rules, which add educational use to the list of copyright infringement exceptions. According to the EU Commission, the language used in the law is too broad, damaging the rights of educational publishers.

“Broad exceptions in copyright law are applied in a way that appears to be detrimental to right holders. EU stakeholders are particularly concerned about the fair dealing exception for educational purposes and the exception for non-commercial user-generated content,” the Commission writes.

The same issue was previously pointed out by the US Government. That’s also true for the second problem, Canada’s lack of a takedown procedure to ensure that infringing content is removed by online service providers.

Canada previously implemented a “notice-and-notice” scheme. This only requires services to alert infringing parties, but it should ideally be complemented with a takedown requirement, the Commission notes.

“Stakeholders indicate that the ‘notice and notice’ regime for online copyright infringements, which came into effect in January 2015, still needs to be supplemented by a ‘notice and take down’ requirement, as well as by other measures to encourage all players to address online infringements in an effective way,” the Commission writes.

“There is currently no requirement for the internet service provider (ISP) or the user to take down infringing material and the only way to enforce a takedown is via the courts,” it adds.

The repeated use of the term “stakeholder” shows that the Commission heavily relies on input from copyright holders. While this is common, it may not be the most balanced approach.

Finally, the Commission also points out that many pirate websites are still hosted in Canada. This is a concern, it writes, as rightsholders are not able to request an injunction to have websites blocked by ISPs.

That last complaint is outdated, as Canada’s Federal Court recently issued the country’s first website blocking order. This is likely because copyright holders already submitted their complaints before that happened.

All in all the complaints are nothing new for Canada’s Government so whether they will make an impact has yet to be seen. The country previously wasn’t very impressed by “one-sided” foreign complaints on its copyright policies.

Canada is working on an update of its copyright law. Earlier this year, the Government’s Standing Committee on Industry, Science and Technology clearly rejected a non-judicial site-blocking regime, while it advised keeping the current safe harbor policy intact.

No foolin‘—the 2010s were a crazy decade for tech

Spaceflight lived, software ownership died, and net neutrality lived and died.

Big Bird at the 2013 Qualcomm CES Keynote

Look, we can't do this without at least mentioning the 2013 Qualcomm CES Keynote, perhaps remembered best as "Born Mobile." It had everything: over-enthusiastic millennials, Guillermo del Toro, Maroon 5, NASCAR, surprise Steve Ballmer, and Big Bird in a tie. Watch it sometime. (credit: Lee Hutchinson)

It's been quite a decade. Tech surfed into the 2010s upon a huge wave of optimism and connection (Facebook!) but eventually wiped out on the shoals of cynicism and tribalism (Facebook!). Along the way, we cavorted with porn trolls, wept over the corpse of net neutrality, and stared into the unblinking eye of the digital surveillance state.

Here are the trends and tales that defined the last ten years of tech in the eyes of Ars. Treasure them in your hearts, for one day you might be called upon to retell the Legend of Prenda Law or to let your grandchildren know what it was like to believe in social media as a force for good. And lo, verily, they shall gaze upon you with wide eyes and ask, "No foolin'?" And you can nod sagely and stare off into the far distance and say: "No foolin', kids. I lived it."

Those crazy court cases

It’s hard to look back at any decade in science and technology without a few cameos from the legal system. The 2010s, of course, were no different: Apple v. Samsung just ended a long battle over smartphone feature patents that impacted the marketplace (and company pocketbooks). And Oracle v. Google is about to spill into the 2020s and potentially reverse a disastrous decision regarding software APIs.

FACT Partner Up With UK Copyright Troll Outfit

FACT, an anti-piracy outfit known for taking action on behalf of clients including Sky and the Premier League, has teamed up with copyright troll outfit Hatton and Berkeley. The surprise pairing is revealed in submissions to the UK’s Companies House, which also show that 70% of FACT’s shares are now owned by a company that made a significant loan to FACT.

The Federation Against Copyright Theft, or FACT as it’s more commonly known, has developed a reputation for cracking down on mostly video-based piracy in the UK.

During its recent history, FACT has worked on behalf of the Premier League, Sky, and BT Sport, among others. FACT’s activities in this respect have been fairly broad, from tackling IPTV providers and sellers, creators and distributors of Kodi add-ons, to bringing prosecutions against pub landlords who show live football without an appropriate license.

Recently, however, it appears that FACT has struck up a partnership with H&B Administration LLP, a company closely connected to controversial copyright-trolling activities in the UK.

Given FACT’s traditional modus operandi, of not targeting end-users but going after suppliers and facilitators, the pairing comes as a surprise, to say the least. We recently contacted FACT with a request for comment on the partnership but we received no response.

News of the partnership was made public in a filing to the UK’s Companies House, which reveals that FACT Worldwide Ltd became a member of H&B Administration LLP on September 11, 2019.

 

The addition of FACT means that the LLP now has four officers – the (in)famous Robert Croucher, FACT Worldwide Ltd, Hatton & Berkeley Management Ltd, and TCYK LLC – the company behind the Robert Redford movie, The Company You Keep.

H&B previously targeted UK Internet subscribers demanding cash settlements on behalf of TCYK while making various grand anti-piracy announcements that never lived up to their billing. On November 5, 2019, Companies House described H&B Administration LLP as a “dormant company”.

While FACT didn’t respond to our request for comment, Hatton and Berkeley founder Robert Croucher previously told us that the purpose of H&B Administration LLP is to provide an “insured and administrative wrapper” to mitigate risk when suing pirates.

“I can say that these type of proceedings [cases against alleged infringers] are to be wrapped with an insurance policy hereon providing a level of risk mitigation to rights holders seeking reparation for damages sought at trial,” Croucher said.

Quite why FACT has decided to get into bed with H&B remains open to question but if Croucher’s explanation still stands, limiting risk during litigation is a potential plus for the company.

FACT CEO Kieron Sharp is now listed on H&B’s website as part of the team there conducting “civil and criminal enforcement.” Given FACT’s client base of well-known companies such as the Premier League, Sky and BT Sport – all of which have plenty of funds available for their own litigation, even if a case or two went wrong – the news of the partnership with H&B is indeed curious.

That being said, FACT Worldwide’s latest set of accounts may indicate a need for financial caution.

To the year ended December 31, 2018, FACT Worldwide’s revenues were £1,343,310, resulting in a gross profit of £201,907. However, after administrative expenses were deducted, the company made an operating loss of £393,115.

The accounts also reveal that on May 1, 2019, the company underwent a financial restructuring. A company called Global Due Diligence Limited, which gave FACT Worldwide a loan of £1,428,500, repayable in 4.5 years’ time, also acquired 70% of FACT Worldwide’s share capital.

The big remaining question is whether the image of FACT as a strictly professional targeter of piracy facilitators will be blended or indeed confused with H&B’s less palatable penchant for targeting the man in the street, and whether public perceptions of the parties will be adjusted to suit.
