‘Star Trek: Strange New Worlds’ Gets Muppet Fever In Season 4

Star Trek: Strange New Worlds has done a lot of odd things in the course of its five-season mission. We’ve had musicals, fantasy episodes, full-on horror adventures, and even a murder mystery is on the horizon. Now, the show is boldly going in another kooky direction: a puppet episode. Announced today during Trek‘s blockbuster Hall H panel at San Diego Comic-Con, Jordan Canning (who directed season 2’s “Charades”, but perhaps more crucially here, also directed seven episodes of the Fraggle Rock

Why I do programming

This piece was inspired by this post by Aaron Boodman. I remember myself as a calm, quiet kid, happiest when I had a bunch of wires in my hands. My parents used to give them to me as toys along with a screwdriver and an old cassette player I could take apart and try to put back together. I was three years old. I didn’t know what I was doing, but I loved the feeling of exploring the insides of a machine, trying to understand how it works. In first grade, I was introduced to MS-DOS and Logo with

Turn any diagram image into an editable Draw.io file. No more redrawing

Look, we know there are other tools out there. But we built this one because we needed it ourselves. Here's what makes our image to drawio converter different. It Actually Understands Diagrams Here's the thing - most tools just see shapes and lines. Our image to drawio converter sees diagrams. Feed it a whiteboard photo, and it knows that wobbly rectangle is meant to be a process box. Give it a screenshot, and it figures out which arrows connect to which shapes. We spent months training it on r

Meta Debuts More Instagram Protections for Teen Users. Here's What's New

Meta this week unveiled the latest efforts it's making to bolster the safety of teens and kids on its social media apps, with a particular focus on the teen-skewing Instagram.

"We've added new safety features to DMs in Teen Accounts to give teens more context about the accounts they're messaging and help the

SRAM Has No Chill: Exploiting Power Domain Separation to Steal On-Chip Secrets

1 Introduction An increasingly connected world makes us dependent on computing devices that handle a wide range of security- and privacy-critical operations. We use smartphones and watches to manage bank transactions and store biometric information. On the industrial and government side, embedded devices monitor remote system operations and feed data critical to industrial processes and national defense. Physical access to these devices leads to a wide range of security exploits, including imper

Skydance deal allows Trump’s FCC to “censor speech” and “silence dissent” on CBS

The Federal Communications Commission has approved Skydance's $8 billion acquisition of Paramount, which owns CBS. But the agency's approval drew fiery dissent from the only Democratic commissioner, Anna Gomez, after requiring written commitments from Skydance that allow the government to influence editorial decisions at CBS. Gomez accused the FCC of "imposing never-before-seen controls over newsroom decisions and editorial judgment, in direct violation of the First Amendment and the law." Und

How to use AppleCare One with the iPhone Upgrade Program

Earlier this week, Apple announced an all-new AppleCare One subscription service. AppleCare One lets you get AppleCare coverage on up to three devices for $20 per month. Dan Moren at Six Colors got the answer to a something I’d been wondering: can AppleCare One coexist with the iPhone Upgrade Program? One of the nice benefits of the iPhone Upgrade Program is that you pay a single monthly fee to get a new iPhone each year and AppleCare coverage. Apple spokesperson Anna Mitchell confirmed to Si

Galaxy S25 FE leak reveals new colors, bad news for RAM and storage

TL;DR The upcoming Samsung Galaxy S25 FE could have 8GB of RAM and 128GB or 256GB of internal storage. While these may be sufficient for most people right now, the specs aren’t very future-proof, especially given the pace of development of AI features. Samsung is expected to charge about $700 for the base variant of the Galaxy S25 FE, which makes these specs difficult to digest. Samsung is hard at work on its next launch, which is most likely the Galaxy S25 FE. We’ve seen several specs leak f

FCC approves Skydance's $8 billion Paramount acquisition

Regulators won't stand in the way of Skydance's Paramount acquisition. The Federal Communications Commission has approved the $8 billion purchase of Paramount Global and its subsidiaries, including the parent company of CBS Network. In a statement, FCC Chairman Brendan Carr said he welcomes "Skydance’s commitment to make significant changes at the once storied CBS broadcast network." Skydance, he said, has made written commitments to ensure that its "news and entertainment programming will embod

Paramount Has a $1.5 Billion ‘South Park’ Problem

In an interview with Vanity Fair in September, South Park creators Trey Parker and Matt Stone all but swore off satirizing Donald Trump, with Parker noting, “I don’t know what more we could possibly say.” We found out what more they could say yesterday, in brutal fashion. The same day Paramount announced a five-year streaming deal with South Park, including 50 new episodes, the show’s 27th season premiere mercilessly mocked both President Trump and the network for capitulating to his demands, s

She spent 5 years covering tech policy at CNBC, writing about antitrust, privacy, and content moderation reform.

There is no memory safety without thread safety

There is no memory safety without thread safety Memory safety is all the rage these days. But what does the term even mean? That turns out to be harder to nail down than you may think. Typically, people use this term to refer to languages that make sure that there are no use-after-free or out-of-bounds memory accesses in the program. This is then often seen as distinct from other notions of safety such as thread safety, which refers to programs that do not have certain kinds of concurrency bugs

This Simple Bed Frame Took Me Less Than 5 Minutes to Put Together. Yes, I Timed It

CNET's key takeaways The Helix Madison bed frame, available in natural wood or white, is $929 for a queen before sales. It's straightforward to put together and requires no tools. That said, the frame is a little expensive and incompatible with headboards. My beautiful, four-poster bed frame broke a few months ago. Immediately afterward, as I was lying there, slowly sliding to the corner of my mattress that had plummeted to the ground (from a decent height, I might add), I cursed that antiq

PSA: SQLite WAL checksums fail silently and may lose data This is a follow-up post to my PSA: SQLite does not do checksums and PSA: Most databases do not do checksums by default. In the previous posts I mentioned that SQLite does not do checksums by default, but it has checksums in WAL mode. However, on checksum errors, instead of raising error, it drops all the subsequent frames. Even if they are not corrupt. This is not a bug; it’s intentional. SQLite WAL SQLite introduced WAL in 2010.

Americans Are Obsessed With Watching Short Video Dramas From China

My partner recently confessed something to me about his screen-time habits: When he’s giggling at his phone, he’s often watching short English-language soap operas that have begun showing up on his social feeds. The plots are basic, the acting is exaggerated, and the performers are stereotypically good-looking, but the constant twists and turns keep him spellbound and wanting more. I knew exactly where these videos were coming from. It’s been four years since I first heard about the exploding p

Facebook and Instagram icons are seen displayed on an iPhone. Meta on Wednesday introduced new safety features for teen users, including enhanced direct messaging protections to prevent "exploitative content."

Instagram adds new protections for accounts that primarily feature children

These accounts will automatically be placed into the app’s strictest message settings to prevent unwanted messages, and will have the platform’s “Hidden Words” feature enabled to filter offensive comments. The company is also rolling out new safety features for teen accounts. Accounts that will be placed into the new, stricter message settings inclu

More than you wanted to know about how Game Boy cartridges work

More than you wanted to know about how Game Boy cartridges work By Allison Parrish I set out a while ago to make a Game Boy cartridge from scratch. This is not a novel goal; bootleg Game Boy cartridges have existed almost as long as the Game Boy itself has, and there are many third-party cartridges now available for purchase, or that have copyleft designs. But I wanted to know how Game Boy cartridges work. I was also excited to use the PIO functionality of the RP2040 microcontroller. Now, aft

South Park Locks Into Paramount Plus With $1.5B Streaming Deal

Telegram's crypto wallet goes live to its 87 million U.S. users

Telegram users in the U.S. can now send, receive, and manage cryptocurrency directly inside the app — no downloads, extensions, or separate logins required.

Telegram’s crypto wallet launches in the US

Telegram is expanding access to its crypto wallet for its 87 million users in the U.S. The TON wallet, named because it is built on the TON blockchain, is integrated directly into the Telegram app. By existing within the app, Telegram’s crypto wallet is supposed to form an easier onramp for new crypto users.
