SpaceX’s Starlink satellite internet service became the center of a global outage earlier today, with services having resumed soon after.

There are ways around this, but they don’t have the exciting scalability story and worse, they have to rely on a rather non-tech crutch: human input. Smaller language models fine-tuned with actual human-written answers are ultimately better at generating less biased text than a much larger, more powerful system.
And further complicating matters is that models like OpenAI’s GPT-3 don’t always generate text that’s particularly useful because they’re trained to basically “autocomplete” sentences based on a huge trove of text scraped from the internet. They have no knowledge of what a user is asking it to do and what responses they are looking for. “In other words, these models aren’t aligned with their users,” OpenAI said.
Any test of this idea would be to see what happens with pared-down models and a little human input to keep those trimmed neural networks more…humane. This is exactly what OpenAI did with GPT-3 recently when it contracted 40 human contractors to help steer the model’s behavior.
Once the over-excitement recedes we might be able to get a better understanding of what, or who, is creating real value. Bronwyn Williams, a trends analyst and futurist who also serves as Chief Commercial Officer at Carbon Based Lifeforms was keen to stress that as we shift from the Web 2.0 to Web 3.0 world, we are shifting from demonetization to the re-monetization of the digital commons. By that she means, that with Web 2.0 the modus operandum was the offer of services … See more.
Should you offer fractional shares in yourself and your future success?
Humans could live until the ripe old age of 150 years according to recent research – and scientists are racing to work out how.
Harvard geniuses, biohackers and internet billionaires are all looking for ways that humans can crack the code on aging.
WaitButWhy blogger Tim Urban writes “the human body seems programmed to shut itself down somewhere around the century mark, if it hasn’t already”.
An international team, co-led by researchers at The University of Manchester’s National Graphene Institute (NGI) in the UK and the Penn State College of Engineering in the US, has developed a tunable graphene-based platform that allows for fine control over the interaction between light and matter in the terahertz (THz) spectrum to reveal rare phenomena known as exceptional points. The team published their results today in Science.
The work could advance optoelectronic technologies to better generate, control and sense light and potentially communications, according to the researchers. They demonstrated a way to control THz waves, which exist at frequencies between those of microwaves and infrared waves. The feat could contribute to the development of ‘beyond-5G’ wireless technology for high-speed communication networks.
SpaceX’s Starlink satellite internet constellation sees competition inteslify as Amazon’s Kuiper annonces big launch schedule.
Amazon calls it “the largest commercial procurement of launch vehicles in history.” Amazon’s SpaceX-rivaling internet service Project Kuiper has made a major leap towards becoming operational and catching up with SpaceX’s Starlink, which is already populating our skies.
Amazon selects Arianespace, Blue Origin, and ULA as heavy-lift launch partners to deploy the majority of its Project Kuiper satellite constellation.
Stephen Taylor, assistant professor of physics and astronomy and former astronomer at NASA’s Jet Propulsion Laboratory (JPL), said, “Using the pulsars we observe across the Milky Way galaxy, we are trying to be like a spider sitting in stillness in the middle of her web. How well we understand the solar system barycenter is critical as we attempt to sense even the smallest tingle to the web. The solar system barycenter, its center of gravity, is the location where the masses of all planets, moons, and asteroids balance out.”
So, where is the center of the solar system?
It is not in the center of the Sun as many might assume, instead it is closer to the surface of the star. This is due to Jupiter’s mass and our imperfect knowledge of its orbit.
Back in 1,859, long before the internet, a massive geoelectrical storm knocked out the telegraph systems in the world. Reports were given of telegraph operators being shocked, the paper catching fire, and the equipment being operated without the batteries being connected. This was caused by the massive surge of electrical power caused by the storm. These storms occur when a bubble of superheated gas from the sun hits the earth. These storms cause massive damage to our solar system. This occurrence causes a massive surge in electrical activity and damage. Scientists studying these events have concluded that they occur every 500 years. The event in 1,859, known as the Carrington Event, was the most recent. This could mean that in the year 2,359, another storm would wipe out the entire internet.
The Carrington Event was the largest recorded geoelectrical storm, but it wasn’t the first to happen. An even bigger storm happened in our solar system in A.D. 774, based on readings taken from ice core samples in the Antarctic. The solar flare that was launched from the sun during this event in the Antarctic caused the fastest and biggest rise in carbon-14. Carbon-14 is an isotope of Carbon, which is created from the sun and contains highly radioactive material. Though the Carrington Event was measured via observatories at the time, scientists were able to read the rings in the ice taken from the Antarctic event, which is now known as the Miyake event. Based on those readings, the Miyake event was even greater than the Carrington event. The readings of the ice showed a 14% increase in carbon-14. The Carrington event only saw an increase of less than 1% in carbon-14 readings.
Scientists have a rating system that measures the level of geoelectrical storms based on a scale of 1 to 5. The geoelectrical storms are then given a designation of G1 to G5 based on their intensity. The Carrington event was rated a G5. That would have meant the Miyake event was even more catastrophic in our solar system. A storm that was three times smaller than the Carrington event occurred in 1989. This event took place in Quebec, Canada, and caused the full collapse of the Hydro-Quebec electrical grid. The geoelectrical storm was so powerful that it also caused damage to a circuit breaker in New Jersey. This resulted in the grid’s circuit breakers going off, which caused five million people being without power for nine hours. Should an electrical storm like this occur in currently, the damage would be immeasurable.
