Planting flags in AI coding territory

Answering this often triggers more questions that shouldn't surprise anyone. Do you have some workable requirements? Have you created meaningful tests aligned with those? Can you understand and fix your code when those tests fail? Are you seeing opportunities to delete code in a way that enhances its value by reducing its liability? In all of these questions, code is ingrained with purpose, hampered by ambiguity, and therefore very much human, even when it lies forgotten in some machine wher

SpaceX Starship explodes during engine test, Musk shares preliminary investigation results

Facepalm: SpaceX was preparing its Starship rocket for a 10th flight test – initially scheduled for June 29 – when it exploded during a static fire at the Starbase launch site in Texas shortly after 11 pm MT on Wednesday. The launch timeline is now unclear following the incident. A video shared by NASA Spaceflight shows a powerful explosion lighting up the Texas night sky during what was supposed to be a routine engine test. Cameron County officials confirmed the incident and said no one was in

SpaceX Starship Explodes in Spectacular Fireball at Texas Test Facility

The upper stage prototype, designated Ship 36, exploded shortly before midnight local time on June 18 during routine preparations for an upcoming test flight. SpaceX is in the midst of preparing for Starship’s next fully integrated test, known as Flight 10. The last several tests haven’t gone well, but this prototype never even left the ground. The explosion—as shown in spectacular footage from NASASpaceFlight.com—occurred at SpaceX’s Massey facility, a test site located several miles from the

SpaceX's Starship explodes on the ground during a routine test

A SpaceX Starship vehicle has exploded yet again, and this time, it happened before it even took off. NASASpaceflight has captured the event in a livestream, wherein you can see the spacecraft (Ship 36) suddenly explode into a fireball after the company tested its forward flap and just before it was supposed to conduct a static fire test. The company said on X that on June 19 at approximately 12AM Eastern time, the Starship it was preparing for its 10th flight test "experienced a major anomaly"

SpaceX's Starship explodes again while still on the ground

SpaceX has made excellent progress with its Starship rocket. The stainless steel vehicle can now explode before even leaving the Earth. The latest setback happened just before a planned static fire this morning. The rocket was fueled ahead of a test firing of its Raptor engines, but abruptly exploded. The explosion occurred on a test stand, and it is unclear how much damage the facility sustained. According to SpaceX, "a safety clear area around the site was maintained throughout the operation

I Spent Weeks Using Orb: It's Unlike Any Internet Speed Test I've Ever Used Before

Internet speed tests aren't just for people who obsess over their internet connection. If you're having an inevitable home internet slowdown, my first recommendation is always to start with a speed test. In fact, I’ve tested and used dozens of internet speed tests -- the market is pretty saturated with them. Ideally, the best internet speed test is one that diagnoses your bandwidth blues as easily as possible -- no ads, no extra features you can’t make sense of and no slowing down your Wi-Fi. S

SpaceX’s next Starship just blew up on its test stand in South Texas

SpaceX's next Starship rocket exploded during a ground test in South Texas late Wednesday, dealing another blow to a program already struggling to overcome three consecutive failures in recent months. The late-night explosion at SpaceX's rocket development complex in Starbase, Texas, destroyed the bullet-shaped upper stage that was slated to launch on the next Starship test flight. The powerful blast set off fires around SpaceX's Massey's Test Site, located a few miles from the company's Starsh

SpaceX’s Starship blows up ahead of 10th test flight

One of SpaceX’s Starship launch vehicles exploded on a test stand in Texas late on Wednesday night, as the company prepared for the tenth test flight of the heavy-lift rocket system. SpaceX said “all personnel are safe and accounted for” in a post on X, and claimed there are “no hazards to residents in surrounding communities.” The company did not provide an explanation for the explosion. It’s not immediately clear what impact this will have on SpaceX’s development of the Starship rocket syste

SpaceX Starship explodes again, this time on the ground

On Wednesday, June 18 at approximately 11 p.m. CT, the Starship preparing for the tenth flight test experienced a major anomaly while on a test stand at Starbase. A safety clear area around the site was maintained throughout the operation and all personnel are safe and accounted for. Our Starbase team is actively working to safe the test site and the immediate surrounding area in conjunction with local officials. There are no hazards to residents in surrounding communities, and we ask that indi

The unreasonable effectiveness of fuzzing for porting programs

A simple strategy of having LLMs write fuzz tests and build up a port in topological order seems effective at automating porting from C to Rust. Agents are starting to produce more and more code A week or 2 back, I was reflecting on some code Claude had generated for me and I had a sort of moment of clarity. "Clarity" might be overstating it; more like the type of thought you have in the shower or after a few beers. Anyway. The thought was: LLMs produce more and more code, and they'll eventua

Honda Unexpectedly Enters the Space Race With First Successful Rocket Launch

In a bizarre twist, Honda, the Japanese car manufacturer, has taken its engineering off-road—and into space. The company launched and landed a prototype reusable rocket on Tuesday, June 17, marking a key milestone toward its newfound goal of achieving suborbital spaceflight by 2029. In the surprise announcement, Honda R&D—the company’s research arm—said it successfully completed the first launch and landing test of its 20.6-foot (6.3-meter) experimental reusable launch vehicle after reaching an

Stay on Top of These 6 Blood Tests to Make Sure You're Monitoring Your Health

Having your blood drawn might not be much fun, but regular diagnostic tests of your blood can detect diseases early for treatment and give your doctor and medical providers critical information about how well your body is functioning. The proper frequency of these blood tests depends on your age and personal health status -- the most important thing is to ask your doctor which tests you need and when you need them.

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

Instagram is running another test of a repost feature

Best Meat Thermometers for 2025

James Bricknell/CNET The most important part of any thermometer testing is accuracy. We weight this criteria most heavily when compiling entries to the best list, and it is the most scientific of the tests. We use a medical-grade thermometer as our baseline for accuracy and test the meat probe variance to that temperature. Ice water testing Testing the accuracy of a thermometer usually involves a cup, some ice cubes, and water. Due to the nature of water it can be a liquid and a solid at 32F

Glenn Close Is Joining ‘The Hunger Games’

Confirmed by Lionsgate at CinemaCon Europe this morning (via Deadline), Close and Porter will play Drusilla Sickle and Magno Stift, respectively. Sickle is the sinister Capitol escort to the Tributes from District 12 called up for the 50th Hunger Games–including the

DARPA program sets distance record for power beaming

In a series of recent tests in New Mexico, the Persistent Optical Wireless Energy Relay (POWER) program achieved several new records for transmitting power over distance. The team recorded more than 800 watts of power delivered during a 30-second transmission from a laser 8.6 kilometers (5.3 miles) away. Over the course of the test campaign, more than a megajoule of energy was transferred. Previously, the greatest reported distance records for an appreciable amount of optical power (>1 microwat

No Kings: protests in the eye of the storm

As President Donald Trump kicked off a birthday military parade on the streets of Washington, DC, what’s estimated as roughly 2,000 events were held across the US and beyond — protesting Trump and Elon Musk’s evisceration of government services, an unprecedented crackdown by Immigration and Customs Enforcement (ICE), and countless other actions from the administration in its first five months. Held under the title “No Kings” (with, as you’ll see, one conspicuous exception), they’re the latest in

The Best Water Filter Pitcher for 2025

As mentioned earlier in this article, there are quite a variety of contaminants worth removing from your tap water. The team here at our lab settled on three primary tests to benchmark the efficacy of these filters: TDS, pH and chlorine. Before we began the actual testing process, each pitcher was removed from the packaging, cleaned and then prepared per the manufacturer's instructions. This is very important, as most of these filters utilize activated carbon filtration, which will deposit sedim

RFK Jr. Orders HHS to Give Undocumented Migrants’ Medicaid Data to DHS

With demonstrations ramping up against the Trump administration, this week was all about protests. With President Donald Trump taking the historic step to deploy US Marines and the National Guard to Los Angeles, we dove into the “long-term dangers” of sending troops to LA, as well as what those troops are permitted to do while they’re there. Of course, it’s not just the military getting involved in the LA protests against the heavy crackdowns by Immigration and Customs Enforcement (ICE). There’

Another one for the graveyard: Google to kill Instant Apps in December

Apps used to be the measure of a mobile platform's worth, with Apple and Google dueling over who could list the most items in their respective stores. Today, the numbers don't matter as much—there are enough apps, and Google's attempt to replace parts of the web with apps is going away. Instant Apps, a feature that debuted in 2017, will reportedly be scrapped in December 2025. In its place, you'll just have to use the Internet.
