    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.

  • Quizzino della domenica: dadi riordinati

    @matematica - Riordinare i dadi non è sempre facile.

  • @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.

    @Sascha thank you Sascha. I used to be stuff like that on my other VPS - which had a Ghost-CLI installation. With YunoHost I don't dare go in the backend to touch anything, lest I disrupt something. I have too many important apps in that installation. I'm not incurring in any extra costs... it's just that a social networking app caches media, avatars and emojis of everyone I follow. I found an old backup from December 2024 when I was only following one account and it was 256 MB! Pruning the list of people I follow - it overlaps with my Mastodon account - may be the way to go 😅​

    @De_TreiasCon "qualche semplificazione c'è" ti riferisci a Yunohost?Sicuramente c'è, mi domandavo se dovendo gestire solo un DB tipo mySQL, un web server tipo Apache (Yunohost non usa Apache) e le 5-6 applicazioni che li usano, avesse senso aggiungere Yunohost.Fino ad ora ho usato solo hosting condiviso quindi nel passare ad un VPS dovrei gestire in più, rispetto ad ora, "solo" gli aggiornamenti del sistema operativo (che però sono automatici), quelli del web server, quelli del DB e configurare il firewall.Il lavoro da fare è questo, quanto sarebbe d'aiuto Yunohost e quanto sarebbe solo un SW in più di cui occuparmi? Non lo so.

    @_elena @christopher ah jellyfin runs fine on a raspberry 3. Just give it a try.Just together with a pi hole on the same pi became a challenge 😉

    Progress update no.3 (perseverance edition) 💪​Several people suggested that I install #YunoHost on my Raspi5 ON TOP of Debian (thank you @jan and @fmors) so I will be trying that tomorrow morning... when my parents are looking after my little one (who's on a 2 week school holiday).This morning I gave up a little too easily because she was playing nearby and my attention was a little scattered.But excited to try out this method tomorrow. Thank you Jan & Fernando 🙏​The Fediverse has THE BEST tech support 😄​
