Astronomers now say the rocket about to strike the Moon is not a Falcon 9

It’s probable that the impact object comes from a Chinese rocket launched in 2014.

About three weeks ago Ars Technica first reported that astronomers were tracking the upper stage of a Falcon 9 rocket, and were increasingly confident that it would strike the Moon on March 4.

This story set off a firestorm of media activity. Much of this coverage criticized SpaceX for failing to properly dispose of the second stage of its Falcon 9 rocket after the launch of NOAA's Deep Space Climate Observatory mission, or DSCOVR, in 2015. The British tabloids, in particular, had a field day. Even the genteel European Space Agency tut-tutted, noting that it takes care to preserve enough fuel to put spent rocket stages into stable orbits around the Sun.

However, it turns out we were all wrong. A Falcon 9 rocket is not going to, in fact, strike the Moon next month. Instead, it's probably a Chinese rocket.

Review: The Book of Boba Fett is lots of fun but it’s really The Mandalorian 2.5

The series never really figured out whose story it wanted to tell. This is not the way.

When The Book of Boba Fett was still in production, creator Jon Favreau jokingly dubbed the spinoff series "The Mandalorian season 2.5." It turns out that wasn't really a joke. I mean, we knew beforehand The Book of Boba Fett would take place in the same timeline. I just didn't expect that four episodes into a seven-episode season, the focus would abruptly shift from Temuera Morrison's iconic titular character—i.e., the supposed star of the series—and the next two episodes would be spent mostly catching up with our favorite characters from The Mandalorian.  

It was (ahem) an interesting creative choice that generated considerable Internet discussion (and more than a few mocking memes). The good news is that, on the whole, The Book of Boba Fett is still a hella entertaining Star Wars adventure. And it closed the season with an action-packed, crowd-pleasing hour-long action sequence in which Boba and his various allies took on the nefarious Pyke syndicate in a climactic battle—with a squee-worthy heartfelt reunion for good measure.

The bad news is that the series never really figured out whose story it wanted to tell, essentially squandering the promise of the first four episodes by failing to develop its supposedly main character in any meaningful way.

The weekend’s best deals: Kindle Paperwhite, Nintendo Switch, and more

Dealmaster also includes the Google Chromecast, AirPods Pro, and Amazon Fire tablets.

The weekend’s best deals: Kindle Paperwhite, Nintendo Switch, and more

It's the weekend, which means it's time for another Dealmaster. Our latest roundup of the best deals from around the web includes a nice price on Amazon's newest Kindle Paperwhite, as the e-reader is currently down to $110 at various retailers. That's $30 off Amazon's MSRP and the second-lowest price we've tracked. The only time we've seen the device fall lower was around Black Friday, when it was available for $5 less. Amazon includes three months of its Kindle Unlimited ebook service as part of the deal, but be aware that this will be set to auto-renew by default.

We gave the latest Kindle Paperwhite a rave review when it released last year. Compared to its predecessor, it adds a more spacious display (now at 6.8 inches, up from six), a USB-C port, a better frontlight, more consistently responsive performance, and improved battery life (which Amazon rates at roughly 10 weeks per charge). Like the last model, it's waterproof (with an IPX8 rating) and it can connect to Bluetooth headphones and speakers for playing audiobooks. And like all Kindles, it still has access to an enormous library of things to read. It's a bit bigger than the last model, and if you just don't want to lock yourself into Amazon's ecosystem, Kobo's Clara HD is a decent alternative (albeit one without waterproofing and Bluetooth) that's also on sale as of this writing. But for most people, the Paperwhite is the e-reader with the best combination of features and value.

That said, it's worth noting that the Kids version of the Kindle Paperwhite is also on sale for $10 more. Though this variant is marketed towards children, it has all the same features as the standard Paperwhite, plus a case, a longer warranty (two years instead of one), and, most notably, no ads on its lock screen or homepage by default. (The latter is a feature that costs an extra $20 on the standard, ad-supported model.) If you're buying for a young kid specifically, the standard Kindle Kids e-reader is likely a better value, but older readers willing to pay a little extra might want to consider this model instead.

Pirated Oscar Screeners Have Become a Rare Breed

Twenty years ago, screener copies of all Oscar-nominated films leaked online before the official awards ceremony. Today, screeners have become a rare breed. This isn’t only the result of increased anti-piracy protection. In fact, the shift to shorter release windows and streaming premieres likely had a much bigger impact.

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

oscarsThe Oscars are the most anticipated movie awards show of the year, closely followed by hundreds of millions of movie fans around the world.

It’s also a special event for movie pirates. Traditionally, the Oscar winners see a surge in unauthorized downloads. And in anticipation of the big day, pirated copies of award-screeners would often leak early.

From 100% to 9%

In the early 2000s, it was pretty common to see screeners of all Oscar contenders leak online before the winners were announced. This has changed dramatically over the years. In the past decade roughly half of all nominated movies leaked as a screener and, last year, this percentage dropped below 10% for the first time.

New data released by Oscar piracy watcher Andy Baio suggests that the downward trend continues. For all Oscar-nominated films of this year, only three screeners leaked, which is on par with last year’s all-time low.

pirate screener stats

Granted, there are still a few weeks to go before the awards ceremony. However, typically all screeners have come out already in February, so it is safe to say that the downward trend is intact.

The same graph also includes another key statistic. The number of “high-quality” leaks remains very high. These are ripped HD streams or Blu-Rays that are not screeners. Last year, a high-quality copy of all Oscar contenders was available before the awards, and this year 88% leaked already.

Screeners are Rate, Leaks Aren’t

This means that, while screeners rarely leak nowadays, leaks are still quite common. This can in part be explained by a drastically changing movie industry and the rise of streaming services.

Of all films that were nominated for the 94th Academy Awards, more than half premiered on a streaming service. Netflix has a dominant position, but HBO Max and Disney+ contributed to this change as well.

When a film premieres on a streaming service it’s generally available on pirate sites on the same day. These non-existing release windows are different from the months people have to wait for some theatrical-only releases.

As a result, pirates can get their hands on unauthorized copies of the movies much quicker. This effect is nicely illustrated by the median number of days between a movie’s official release and a pirated leak. That number tanked after 2020.

media leak

This doesn’t mean that screeners no longer exist in the streaming era. Depending on the release date, voters still need early access to a Netflix or Disney+ film if it’s not on the platform yet.

‘The Power of the Dog’ Screener

This was also the case for “The Power of the Dog,” which leads the Oscars field this year with 12 nominations. The film, starring Benedict Cumberbatch and Kirsten Dunst, was released on December 1st but a screener copy already leaked last September.

Several other Netflix titles also leaked early but none of them were nominated. These leaks are not necessarily awards screeners. Information we received from the leaker suggests that they are linked to film festival screeners.

The other Oscar-nominated films that had leaked screeners are “Cyrano” and “Drive My Car.” These are not streaming releases but the latter has an interesting angle, as it was leaked by a group that used the “OSCAR” tag. This was prophetic, as the Japanese film received four Oscar nominations.

We expect that the screener heydays will never return. Pirates will still publish them if there’s no high-quality copy online yet but with shorter or non-existing release windows, there are simply fewer opportunities.

Sony invites you to go for the gold with a $3600 Walkman

The Olympics are in full swing in Beijing, but Sony wants you to know that you can bring home a little gold metal of your own in the form of the Walkman NW-WM1ZM2. You don’t have to train for years to get one, but you do need to shell out $3600.

It’s the latest addition to Sony’s High-Resolution Walkman line, which debuted back in 2014.

You could pick one up for about $300 back then. The good news is that you don’t have to shell out twelve times that much for the ostentatious gold WM1ZM2 if you want to immerse yourself in what Sony calls “sublime, nuanced sound.”

You can opt instead for the NW-WM1AM2. It’s priced at a much more reasonable $1300.

Sony says you won’t get quite the same audio experience, however. The WM1ZM2’s gold-plated copper chassis apparently makes the music sound even better than it does coming from the WM1AM2’s workmanlike aluminum body.

So what, exactly, are you getting when you shell out just a little bit more than you would for a pair of iPhone 13 Pro Max 1TB? A quarter of the storage in one of those iPhones, for starters — or 128GB in the case of the more pedestrian WM1AM2. You can, however, add more storage via a micro SD slot.

The top-end WM1ZM2 packs a Kimber Kable to transmit the best possible audio to the Walkman’s balanced headphone jack. Kimber, in case you’re not familiar, has been making ultra-high-end, handcrafted audio cables and components for more than 40 years. By high-end, we’re talking $470 3-foot 3.5mm male-to-male cables.

Both models feature 5-inch full HD touchscreen displays and batteries rated for 30 to 40 hours of FLAC listening. WiFi connectivity comes standard allowing you to stream your high-resolution tunes in addition to playing them back from the internal storage.

Sony may have had its fair share of trouble selling smartphones and laptops over the years, but the company always seems to find a group of consumers willing to line up for its high-end audio products.
