Chevron and Williams are big winners in the race to power artificial intelligence as they build out gas-fired power plants and pipelines.

Dumanshu Goyal discusses optimizing data layers for low-latency workloads like AI feature stores. Drawing lessons from NASA's Space Shuttle, he explains how proxy architectures introduce hidden CPU costs, elevated tail latencies, and blast-radius risks. He demonstrates how direct-access Valkey architectures achieve microsecond latency, improve resilience, and slash infrastructure costs. By Dumanshu Goyal

At the Black Hat security conference, the AI giant revealed new details about how its agents went rogue, hacked several other companies—and did it all right under the company’s nose.

Builder Journal · Mars Environmental Dynamics Analyzer (MEDA) Virtual Sensor Recovery Ten times in a row I predicted what my next submission would score before I uploaded it. The worst miss was 0.0025 on a number around nineteen. I took that as confirmation that the physics underneath was correct. It was confirmation that I can do arithmetic. Two days before this competition closed I pointed a review at my own endgame, expecting notes about the code. It came back with three errors and none of them were in the code. All three were in my reasoning, and all three had the same shape: I had run something that felt like a measurement and was not one. This is the fourth entry in this series and the one I would keep if I had to burn the other three. The models are competition-specific. This part is not. The competition in one breath Perseverance carries an environmental station called MEDA. Some of its surface pressure readings are missing, and the competition is to reconstruct them. Scored on mean squared error. The wrinkle is the split. Training covers sols 1 through 100, when pressure is climbing toward its seasonal peak. Test covers sols 201 through 300, when it is falling hard toward the aphelion minimum. Sols 101 through 200 do not exist in either file. Every prediction is outside the range the model was fit on. The first entry covers the first submission, which contained no machine learning at all and took the top of the board at 61.04. Six weeks and seven versions later the public score was 18.99. Almost everything in between was selected by one signal. Not cross-validation. Cross-validation here can only hold out sols from the rising limb, so it is structurally blind to the regime I am scored on. The leaderboard was the only thing that could see the falling limb, so the leaderboard picked every scalar that mattered: the residual shrink, the blend weight, a constant seasonal offset, a diurnal scaling. Hold onto that. It becomes the joke about four hundred words from

Nikita Bier was the face of some of the platform's biggest changes.

Although no one captured a direct image of the impact, scientists have detected signals confirming the rocket hit the lunar surface. Orbiters could provide the first images of the crash site in the coming days.

X head of product Nikita Bier is stepping down and says he will move into a role as an advisor, writing that "it's time to pass the torch and demote myself to my natural state: a poster." He shared the update just over a month after celebrating his one-year anniversary on the job, and just […]

Schwartz is well-qualified for the role, but crashed and burned in Senate hearing.

Venture firms are turning to creators to build trust with the next generation of founders before a check is ever written. It’s a trend that’s been building with a16z’s acquisition of Erik Torenberg’s Turpentine podcast and OpenAI’s acquisition of TBPN. Lightspeed Venture Partners just made its own notable hire in that vein, bringing on Claire Zau, a seed investor with a major following on Instagram and […]

Anthropic and OpenAI models’ unprompted actions forced halt to UK cyber tests.

Reddit says the beloved site is used for some "bad behavior."

Security researcher James Kettle tried to push the limit of AI’s hacking abilities—and discovered how effective it can be when combined with human expertise.

The gossip blogger was on TikTok covered in what appeared to be blood and wielding a knifelike object before the platform cut his stream. He’s since been hospitalized.

"The models are forecasting something outside the envelope of anything we have ever observed."

Google's AI brain drain continues.

The owner had already asked for the alert emails to stop. A fix shipped. Then another email landed. Then another. "ong it just ssent me abother email," he said, voice-dictated, unedited. Fifteen minutes later: "go another one." The system was reporting an outage that did not exist. The Transport That Only Ever Failed A 14-PR merge train had just moved every cron producer's alerting off shared email and onto Buzz, a Nostr-relay team chat. One producer per PR, each with its own liveness contract and a bead receipt. It shipped cleanly. But the library backing those producers carried a default that had only one job: fail. AF_BUZZ_CMD = " ${ AF_BUZZ_CMD :- af_default_buzz_post } " af_default_buzz_post returned 1 with "no Buzz transport injected". Every caller that sourced the library (which is every cron producer) exhausted its Buzz retries and fell through to the email floor. The system reported a false Buzz outage while the relay was healthy. It did this 2 to 5 times per hour. Evidence arrived in the logs: 581 dedup markers, a steady stream of "[INTENT ALERT FLOOR: Buzz unreachable]" emails, and sweep.log showing buzz=ok only for the handful of callers invoked through the CLI entrypoint rather than by sourcing the library. That asymmetry was the bug. The CLI had a one-line fixup swapping in the real transport, annotated in a comment as "the library path is unchanged". The library path did not, and the cron producers all take the library path. The fix promoted the real transport to the default for both seams. af_buzz_transport already discovers the installed buzz-notify.sh and already fails closed when it is genuinely missing. The dead CLI fixup was deleted. Fail-closed behavior survives, but now it is conditional on genuine absence rather than on every caller remembering to opt in. Why not migrate callers one at a time? Because the per-caller route leaves the next new producer to rediscover this the same way. Flipping the default fixes the class, not the instance. The

Chinese researchers have shown that AI models have the capacity to act like aggressive and adaptive computer viruses.

Reddit is expanding its moderation tools and building stronger abuse prevention systems that it says could eventually reduce communities’ reliance on karma and account-age requirements, making it easier for legitimate newcomers to participate.

The Cosmos EV is now slated for release in the second half of 2027. CEO Silvio Napoli said he's focused on getting the EV right, as well as its nearer-term robotaxi project with Uber and Nuro.

Company noted for building quantum annealers now also making gate-based hardware.
