Killing the Mauna Loa observatory over irrefutable evidence of increasing CO2

Column When you don't like the message, what do you do? You shoot the messenger, of course. That's the strategy being employed by U.S. President Donald Trump's administration as it works to avoid, ignore, or bury data that prove the reality of anthropogenic global warming and its evil twin climate change. Case in point: The Trump administration recently released its draft budget [PDF] for the country's premier analytical agency focused on Earth systems, the National Oceanic and Atmospheric Adm

Show HN: My GPU Fan Saga – A DIY ATX Fan Controller

Having a problem-solving mindset is incredibly valuable and rewarding, especially when it leads to exciting DIY adventures. My latest experience with a noisy GPU fan turned into just such an opportunity. It guided me through fascinating explorations involving ATX power, MOSFET motor drivers, Pulse Width Modulation (PWM), ATTiny85's bit-banged 1-wire bus, and a DS18B20 temperature sensor. While many ready-made solutions exists, this project provided me with invaluable learning and immense satisfa

Is Your Iced Coffee Making You Dehydrated in the Summer Heat? I Asked the Experts

As the summer sun beats down, we should all stay hydrated, as dehydration can increase our risk of heat exhaustion and heat stroke. However, when I saw the National Weather Service in Las Vegas advising residents across parts of California, Nevada and Arizona to stop drinking caffeine in extreme heat to prevent dehydration, I wondered if that was taking things too far. To find out whether caffeine actually causes dehydration to the point where you need to put your iced coffee down, I consulted

The surprising geography of American left-handedness (2015)

A pre-K teacher in Oklahoma is making news this week after forcing a left-handed 4-year-old boy to write with his right hand. The boy was sent home from school with an article discussing left- and right-handedness. The article mentions historic attitudes toward left-handedness that associate it with evil and the devil. It's written carelessly enough that it isn't clear whether the writer believes left-handedness is still seen as evil or whether that was only the case in the past. Regardless, it

Computer Glitch Grounds Every Alaska Airlines Flight

A computer outage forced Alaska Airlines and its subsidiary Horizon Air to ground all flights Sunday night, halting operations across the board. On Monday, the airline said that operations were coming back online. The airline requested a system-wide ground stop from federal aviation authorities at about 11 p.m. ET on Sunday night. That stop remained in effect until around 2 a.m. ET Monday, when the Federal Aviation Administration confirmed it had been lifted. But disruptions didn’t end there. A

Async I/O on Linux in databases

I've been working on a complex multi-model database for a few weeks now, and recently I took time to simplify and test out an idea I had on a simple key-value database. I started with the basics: A hash table in memory, a simple append-only log for persistence and durability, and the classic fsync() call after every write to the log for durability. It worked, but wasn't as fast as it could be. In Kevo, that's the approach I use, but in Klay (not public yet, but will be open sourced when ready)

EPA says it will eliminate its scientific research arm

The Environmental Protection Agency said on Friday that it would eliminate its scientific research arm and begin firing hundreds of chemists, biologists, toxicologists and other scientists, after denying for months that it intended to do so. The move underscores how the Trump administration is forging ahead with efforts to slash the federal work force and dismantle federal agencies after the Supreme Court allowed these plans to proceed while legal challenges unfold.

Netflix is already using generative AI in its original shows

Netflix admitted during its earnings call on Thursday that it used generative AI to create VFX in The Eternaut, a Netflix original from Argentina that was released in April 2025. The company's co-CEO Ted Sarandos said that generative AI was specifically used for a VFX shot in the post-apocalyptic drama, but the move is one of several ways Netflix is embracing AI. According to Sarandos, the creators of The Eternaut wanted to include a shot of building collapsing in Buenos Aires, and rather than

Trump’s Cabinet Is Cashing in on Crypto

Congress’s big “Crypto Week” might have faded into the background a bit due to cryptic messages Donald Trump left in a birthday note to Jeffrey Epstein, but Republicans in the House and Senate did, in fact, manage to pass a couple of laws that will establish loose, industry-friendly regulations for cryptocurrency. Which means it is a perfect time to be reminded that the Trump administration is packed with people who stand to benefit from cryptocurrency being mainstreamed. Trump himself, of cour

Chinese hackers breached National Guard to steal network configurations

Salt Typhoon is a Chinese state-sponsored hacking group that is believed to be affiliated with China's Ministry of State Security (MSS) intelligence agency. The hacking group has gained notoriety over the past tw

How to Get Foreign Keys Horribly Wrong

Constraints keep the integrity of your system and prevent you from shooting yourself in the foot. Foreign keys are a special type of constraint because, unlike unique, check, and primary keys, they span more than one relation. This makes foreign keys harder to enforce and harder to get right. In this article, I demonstrate common pitfalls, potential optimizations, and implicit behavior related to foreign keys.

Netflix’s first show with generative AI is a sign of what’s to come in TV, film

Netflix used generative AI in an original, scripted series that debuted this year, it revealed this week. Producers used the technology to create a scene in which a building collapses, hinting at the growing use of generative AI in entertainment.

Trump's firing of Democratic FTC commissioner was unlawful, judge rules

Rebecca Kelly Slaughter, one of the Democratic FTC Commissioners President Trump had fired back in March, said she looks forward to getting back to work. US District Judge Loren AliKhan has just ruled that her removal from the agency was "unlawful and without legal effect" and that she was still a "rightful member" of the commission. The judge explained that the firings violated protections that prevent a president from unilaterally removing officials at independent agencies. In her statement a

ChatGPT can now browse and perform web-based tasks for you

In a quick live stream today, OpenAI announced ChatGPT agent, which improves on its promising, but limited Operator feature announced a few months ago. Here’s how it works Operator meets Deep Research What OpenAI did was combine Operator, which already had agentic browsing capabilities, and Deep Research, which can quickly consume, understand, and infer on website content.
