Why JPEGs Still Rule the Web After 30 Years

A version of this post originally appeared on Tedium, Ernie Smith’s newsletter, which hunts for the end of the long tail. For roughly three decades, the JPEG has been the World Wide Web’s primary image format. But it wasn’t the one the Web started with. In fact, the first mainstream graphical browser, NCSA Mosaic, didn’t initially support inline JPEG files—just inline GIFs, along with a couple of other formats forgotten to history. However, the JPEG had many advantages over the format it quickl

The X-Men Join the Fight In Your First Look at the Next Issue of ‘Godzilla Destroys the Marvel Universe’

Godzilla’s been having a comics cameo queen moment for a while now, and Marvel has been celebrating the Big G’s 70th anniversary in style with a series of fun one-issue crossovers with a whole host of Marvel heroes, from the Fantastic Four to Spider-Man. But the fun’s over now: Godzilla’s here to stomp over the Marvel Universe for real, and as things get from bad to worse for heroes and villains alike, it’s almost time for mutantkind to enter the fight to save Earth. Gerry Duggan and Javier Gar

No Kings, Just Water

It was a lovely day for a protest until the cops decided to riot. Millions took to the streets on Saturday for No Kings Day, nationwide protests in cities big and small, timed to provide counter-programming for Donald Trump’s own military parade in Washington D.C.—an embarrassing spectacle that coincided with the president’s 79th birthday. Los Angeles, the second largest city in the country, had its own No Kings protest downtown that saw tens of thousands turn out. And it was incredible to witn

DC Studios Has Found Its Clayface

Clayface keeps picking up heat at DC. After a reportedly barnstorming pitch and script from Mike Flanagan, James Gunn and Peter Safran’s DC Studios has run forward to make the Batman rogue one of the first big stars of the new DC universe–and now we know who’s going to be playing him. Deadline reports that Tom Rhys Harries has been cast in the title role in what will now be the third major film out of the rebooted DC universe after Superman and Supergirl (formerly titled Supergirl: Woman of Tom

Rocket Companies Like SpaceX May Soon Pay Per Pound to Use the Sky

The skies may no longer be free for the space industry. Rocket companies like SpaceX and United Launch Alliance (ULA) may soon be required to pay a fee to support FAA oversight and airspace coordination, part of a broader effort to keep up with the growing launch industry. A budget reconciliation bill released by Senator Ted Cruz last week proposes that the Federal Aviation Administration (FAA) begin charging licensing fees to rocket companies starting next year. The collected fees would go int

Stop Waking Up So Often to Pee in the Middle of The Night. Use These 5 Tips, Instead

There's nothing worse than having to get up and leave your warm, cozy bed when the feeling of having to pee disrupts your sleep. What's even worse is if this happens to you multiple times during the night, significantly interfering with your sleep and making it harder for you to get through the next day. CNET Urine production typically decreases when you sleep, allowing 6 to 8 hours of uninterrupted rest. That's why bathroom breaks can be so annoying, preventing you from getting those hours of

“Have we no shame?“: Trump’s NIH grant cuts appallingly illegal, judge rules

The Trump administration has locked horns with a federal judge who ruled on Monday that more than $1 billion in DEI-fueled cuts to federal health research clearly discriminated against racial minorities and LGBTQ+ people. In what The New York Times dubbed a “damning assessment” of Trump’s motives, Judge Williams G. Young ruled from the bench that the cuts were “void and illegal,” saying it was his “duty” to immediately order funding restored. “I would be blind not to call it out,” Young said,

Switch 2 users report online console bans after running personal game “backups”

Earlier this week, the makers of the popular Mig Flash cartridge, which allows users to play Switch games loaded via an SD card without modifying the console itself, issued a firmware update enabling the cards to run original Switch games on the Switch 2. Since then, though, multiple Mig Flash users are reporting that they've seen their Switch 2 consoles banned from Nintendo's online servers, even in cases where the devices were only used to run backups of legitimate games the users purchased th

The Nissan Leaf Is Back and Looking to Make Up Lost Ground

Finally, after 15 years, we have a new 2026 Nissan Leaf coming. As befits the “truckification” of global car markets, it’s no longer a compact hatchback. Now it’s a compact SUV—or, more accurately, a crossover utility vehicle built on passenger-vehicle underpinnings. The new Leaf will offer a range of up to 303 miles, Nissan says, from a 75-kilowatt-hour battery pack powering a 160-kilowatt (214-horsepower) motor that produces 261 pound-feet (354 newton-meters) of torque. That motor drives the

Gardyn Indoor Hydroponic Garden Review: Better Growing Through AI

I'm in the midst of putting together a buying guide of indoor vertical gardening systems, and the Gardyn—the 30-plant Home 4.0, to be exact—was the first tester to arrive at my house. I had it unboxed and set up within a couple of hours, lights on and water pump running. I'm already a pro! I thought. Sure enough, within a couple of weeks, all of Gardyn's proprietary seed-filled yCubes had sprouted, and a couple of weeks after that, I was harvesting bowlfuls of herbs and salad greens. Even thoug

How AI chatbots keep people coming back

Chatbots are increasingly looking to keep people chatting, using familiar tactics that we’ve already seen lead to negative consequences. Sycophancy can make AI chatbots respond in a way that’s overly agreeable or flattering. And while having a digital hype person might not seem like a dangerous thing, it is actually a tactic used by tech companies to keep users talking with their bots and returning to their platforms.

Former NASA Agent Suggests Government Used UFO Theories To Cover "Stealth Technology"

A former NASA official says he thinks the government uses rumors of alien conspiracies to hide its secrets — a suggestion corroborated by a recent bombshell report about military officials spreading UFO disinformation. In an interview with Fox News, Joseph Gutheinz, a former special agent at NASA's inspector general, said that the US military's clandestine operations are likely behind many UFO conspiracy theories. "I believe early on in the 1940s when all these UFO stories started coming up, i
