Proof that the world can be much stranger than we expect.

One of the quietest revolutions of our current century has been the entry of quantum mechanics into our everyday technology. It used to be that quantum effects were confined to physics laboratories and delicate experiments. But modern technology increasingly relies on quantum mechanics for its basic operation, and the importance of quantum effects will only grow in the decades to come. As such, physicist Miguel F. Morales has taken on the herculean task of explaining quantum mechanics to laypeople in this seven-part series (no math, we promise). Below is the sixth story in the series, but you can always find the starting story plus a landing page for the entire series thus far on site.

Throughout our quantum adventures to date, we’ve seen a bunch of interesting quantum effects. So for our last major excursion, let’s venture into a particularly creepy corner of the quantum wood: today, we’re going to see entanglement and measurement order.

Together, these two concepts create some of the most counterintuitive effects in quantum mechanics. They are so counterintuitive that this is probably a good time to re-emphasize that nothing in this series is speculative—everything we’ve seen is backed by hundreds of observations. Sometimes the world is much stranger than we expect it to be.

Covid-19 has upended churchgoing in the US, and, the impacts are not felt equally.

For Clay Scroggins, preaching on Zoom was never part of the plan. As lead pastor at Buckhead Church in Atlanta, he was accustomed to services in a 3,000-seat auditorium, with live music and a jumbotron for people in the back. But God’s plan is often mysterious, so when the city of Atlanta forced him to shut the church’s doors last spring, Scroggins faithfully moved his ministry online. “Ultimately, we were really informed by Jesus' calling for us to love our neighbors,” he says, “and the most loving thing we could do was to continue to meet virtually.”

And continue to meet virtually they have. Sunday sermons are broadcast live and posted to the church’s YouTube channel for congregants to watch anytime. Bible study and small group meetings have moved to Zoom. Buckhead has even managed to replicate spontaneous church lobby “bump-ins” with video chat breakout rooms for some events. Donations, which provide all of the church’s operating income, remain the same, they just come via a digital collection plate. At Buckhead Church, virtual worship is going so well that some parts of it might be here for good. But not every congregation has been so blessed.

Amazon & eBay Make Progress With Their Pirate Streaming Box Problem

After being heavily criticized due to the prevalence of pirate streaming devices offered for sale on their platforms, Amazon and eBay now appear to be getting on top of the problem. While they haven’t been completely eliminated, illegal devices are now much harder to find. The same cannot be said of pirate IPTV subscriptions, however.

From: TF, for the latest news on copyright battles, piracy and more.

Three years ago, “Kodi Box” fever was ripping through piracy circles, with the popular media player persistently linked to infringing addons providing free access to the latest movies and TV shows.

As time progressed the term “Kodi Box” was regularly used to describe any set-top device that could be used to obtain pirated content for free, while Kodi itself found itself playing a diminishing role as more convenient piracy-focused Android apps came to the fore.

While piracy veterans were more than capable of making their own “Kodi Box”, newcomers and those with less time or patience sought out pre-configured devices on platforms such as Amazon and eBay. In 2017, with both platforms (eBay in particular) hosting thousands of listings for these devices, news of a crackdown emerged.

Amazon Announces New Policy

As previously reported, Amazon updated its terms and conditions, noting that no product offered for sale should “promote, suggest the facilitation of, or actively enable the infringement of or unauthorized access to digital media or other protected content.”

More specifically, Amazon stated that “any streaming media player or other device that violates this policy is prohibited from sale on Amazon.”

Then, in the summer of 2017, media reports suggested that eBay had followed suit but three months later there seemed little change on the platform. So-called “Kodi Boxes” and other piracy-configured devices were still easily found using even the most basic of searches.

Given that almost three years have passed since the Amazon announcement, this week we decided to take a fresh look at both platforms. Copyright holders should be broadly pleased with today’s state of play.

Pirate Devices Are Less Readily Found

In common with our tests in 2017, our first port of call was a basic search for the old favorite – “Kodi Box”. Unlike three years ago, when a fully-loaded device and many others like it filled the first set of results (and indeed the first few pages), eBay in both the US and UK produces not a single result for a “fully-loaded” pirate device in the first pages.

In fact, eBay.co.uk shows just five results and six from international sellers, none of which are devices pre-configured for piracy – a big change from 2017. The same is roughly true for eBay.com, which produces way more results but mainly for remote control units for set-top devices, cufflinks, nail polish, and baseball cards.

The term “fully loaded” – another pirate staple – is also dramatically less useful than it once was. It doesn’t really matter how that term is used now either. “Fully loaded boxes” reveals listings for fishing tackle, “fully loaded” returns high-spec cars, “fully loaded Android” shows books, and “fully loaded TV” conjures up Herbie DVDs.

Other once-popular terms are useless too. “Showbox” delivers display cases for watches and “Popcorn Time” reveals listings for popcorn machines. It’s like 2017 never happened. On top, devices that do claim to be “fully loaded” appear to be loaded with Netflix, iPlayer and similar apps – not exactly what pirates are looking for.

While Amazon was always less of a problem, the same is broadly true there as well. It is still possible to find listings for pirate devices but the easy and traditional ways of finding them don’t work like they used to and casual buyers will probably try somewhere else out of frustration.

Big Improvements – With One Caveat

While pre-configured piracy devices are now harder to find on both platforms, it isn’t particularly difficult to find pirate IPTV subscriptions on eBay or Amazon. The former platform is much more helpful since when typing in the text “IPTV” the site provides some automatic suggestions that send people to the appropriate listings.

Again, the situation is vastly improved or degraded (depending on perspective) when compared to 2017 but for those prepared to keep digging, the products people are looking for are still around. That they are considerably harder to find will probably prove a deterrent to novices, and that will be welcomed by copyright holders.
