    The AI doesn't even need to actually attend the conference. If it knows what kind of stuff you're interested in, it can just generate it.

  • @danjones000 @Matt_Noyes It does not hurt to try to reduce those emissions; reducing any emissions is good.

    But shaming people for using AI as if they are solely responsible for climate change is intellectually dishonest.

    There are plenty of other problems with AI; "burning up the planet" is not a convincing one.

  • Quieting Noisy Resistors

    [Hans Rosenberg] has a new video talking about a nasty side effect of using resistors: noise. If you watch the video below, you’ll learn that there are two sources of resistor noise: Johnson noise, which doesn’t depend on the construction of the resistor, and 1/f noise, which does vary depending on the material and construction of the resistor.

    In simple terms, some resistors use materials that cause electron flow to take different paths through the resistor. That means that different parts of the signal experience slightly different resistance values. In simple applications, it won’t matter much, but in places where noise is an important factor, the 1/f or excess noise contributes more to errors than the Johnson noise at low frequencies.

    [Hans] doesn’t just talk the math. He also built a simple test rig that lets him measure the 1/f noise with some limitations. While you might pretend that all resistors are the same, the test shows that thick film resistors produce much more noise than other types.

    The video shows some rule-of-thumb lists indicating which resistors have better noise figures than others. Of course, resistors are only one source of noise in circuits. But they are so common that it is easy to forget they aren’t as perfect as we pretend in our schematics.

    Want to learn more about noise? We can help. On the other hand, noise isn’t always a bad thing.

  • @danjones000 @Matt_Noyes electricity is only about 1/3 of global emissions. All data centers, including AI datacenters, are only 1% of electricity usage. That makes 0.3% of total emissions.

    Much more emissions are due to cars, meat, cement production and rice cultivation.

    I recognize that AI has a lot of electricity use; it is nothing compared to the other things you do with your time.

    🤦‍♂️UK. ‘Students at the University of Staffordshire have said they feel “robbed of knowledge and enjoyment” after a course they hoped would launch their digital careers turned out to be taught in large part by AI.’Disrespectful to the students https://www.theguardian.com/education/2025/nov/20/university-of-staffordshire-course-taught-in-large-part-by-ai-artificial-intelligence#ai #tech #education

    #ICE arrests #superintendent of #Iowa’s largest school district By Zoe Sottile, Priscilla Alvarez, September 27, 2025 Excerpt: "The school district and #DHS presented starkly divergent portraits of [Superintendent #IanRoberts]. DHS described him as a 'criminal alien' and suggested he was a public safety threat. But at a news conference after his arrest, board president of #DesMoines #PublicSchools Jackie Norris said the superintendent was 'an integral part of our school community' who 'has shown up in ways big and small' for students and staff. And Roberts disclosed his weapon charge, related to a hunting rifle, when he was hired, a district spokesperson told CNN."The arrest spurred a protest outside the federal courthouse in Des Moines. '#Education, not #deportation / Free Dr. Roberts,' read one sign carried by a demonstrator, according to footage from CNN affiliate KCCI. Local education and immigration advocacy groups have rallied behind the superintendent."Read more:https://www.cnn.com/2025/09/26/us/ian-roberts-des-moines-superintendent-arrested-ice?utm_source=firefox-newtab-en-us#FreeDoctorRoberts #FreeDrRoberts #EducationNotDeportation #ICESucks #RacialProfiling #Targeting #authoritarianism #IPreferMyCountryNeatWithoutICE
