On Thursday, a few Twitter users discovered how to hijack an automated tweet bot, dedicated to remote jobs, running on the GPT-3 language model by OpenAI. Using a newly discovered technique called a “prompt injection attack,” they redirected the bot to repeat embarrassing and ridiculous phrases.
The bot is run by Remoteli.io, a site that aggregates remote job opportunities and describes itself as “an OpenAI driven bot which helps you discover remote jobs which allow you to work from anywhere.” It would normally respond to tweets directed to it with generic statements about the positives of remote work. After the exploit went viral and hundreds of people tried the exploit for themselves, the bot shut down late yesterday.

Meteoroid impacts shape planetary surfaces by forming new craters and alter atmospheric composition. During atmospheric entry and impact on the ground, meteoroids excite transient acoustic and seismic waves. However, new crater formation and the associated impact-induced mechanical waves have yet to be observed jointly beyond Earth. Here we report observations of seismic and acoustic waves from the NASA InSight lander’s seismometer that we link to four meteoroid impact events on Mars observed in spacecraft imagery. We analysed arrival times and polarization of seismic and acoustic waves to estimate impact locations, which were subsequently confirmed by orbital imaging of the associated craters. Crater dimensions and estimates of meteoroid trajectories are consistent with waveform modelling of the recorded seismograms. With identified seismic sources, the seismic waves can be used to constrain the structure of the Martian interior, corroborating previous crustal structure models, and constrain scaling relationships between the distance and amplitude of impact-generated seismic waves on Mars, supporting a link between the seismic moment of impacts and the vertical impactor momentum. Our findings demonstrate the capability of planetary seismology to identify impact-generated seismic sources and constrain both impact processes and planetary interiors.

On 4 February 2022, 38 Starlink satellites were destroyed by the geomagnetic storm, which brought significant financial, aerospace and public influences. In this letter, we reveal the space weather process during 3–4 February 2022 geomagnetic disturbances, from the Sun all the way to the satellite orbiting atmosphere. Initiated by an M1.0 class flare and the following coronal mass ejection (CME), a moderate geomagnetic storm was stimulated on 3rd February by the CME arrival at Earth. Subsequently, another moderate storm was triggered on 4th February by the passage of another CME. Model simulations driven by solar wind show that the first geomagnetic storm induced around 20% atmospheric density perturbations at 210 km altitude on 3rd February. The unexpected subsequent storm on 4th February led to a density enhancement of around 20%–30% at around 210 km. The resulting atmospheric drag can be even larger, since the regional density enhancement was over 60% and the satellite orbits were continuously decaying. This event brings forth the urgent requirements of better understanding and accurate prediction of the space weather as well as collaborations between industry and space weather community.

This article tells the story of how photography changed astronomy and how hundreds of astronomers formed the first international scientific collaboration to create the Carte du Ciel (literally, “Map of the Sky”), a complete photographic survey of the sky. That collaboration resulted in a century-long struggle to process thousands of photographic plates taken over decades, with the positions of millions of stars measured by hand to make the largest catalog of the night sky.
Unfortunately, the Carte du Ciel project came at a time when our ability to collect measurements of the natural world was not matched by our capacity to analyze them. And while the project was in progress, new instruments made it possible to study physical processes in distant celestial objects, tempting scientists away from the survey by offering the chance to create new models to explain the world.
For the astronomers working on the Carte du Ciel, no model yet existed that could abstract the positions of millions of stars into a theory of how our galaxy evolved; the researchers instead only had an intuition that photographic techniques could be useful to map the world. They were right, but it took most of a century and the entire careers of many astronomers for their intuition to bear fruit.

Recently, I received a question about which Geiger counter is best suited as a radiation monitor at a weather station. I have been running a uRadmonitor Kit1 for this purpose for several years. However, this kit is not very flexible due to the LAN port, and the measured values can only be stored in a separate, local database via workarounds.
After further research on the Internet, I could not find a suitable design that would meet the requirements of a stationary device as the base of a wireless weather station. A new project idea was born.

i was always bothered by the lack of like official concept art for kim kitsuragi that's available. there's like, three total pictures? which made no sense to me given how he's a main character, he's there with you for most of the game, how can this be all of it. where's the early iterations. alternate designs. turns out it's because they apparently drew him once and were like "oh this is perfect. we can't improve on this. we nailed it" and just moved on

screenshot of text from the Disco Elysium art book. It reads: "Opposite: (163) A monochrome etching of Kim dating back to the early days of pre-production. Kim Kitsuragi, a fan favorite, a man of the people. Kim’s design was a slam dunk from the get-go."

i once joked that given how little insight there is into his creation and how little concept art there was of him, he probably just appeared fully formed in the game one day. apparently i wasn't far off. his portrait is literally from pre-production just with colours slapped on it. "a slam dunk from the get-go". character of all fucking time
